That automotive and technology are closely linked is a fact. That the technology applied to cars has significantly improved their efficiency and performance at a mechanical level, too. But another aspect in which the technology has been massively implemented and which perhaps is not given the importance it deserves, is in the security systems, both active and passive. Thanks to the new systems developed by the manufacturers, we are facing the generation of the safest cars ever manufactured.
Next, we will review the most current and innovative security systems applied by most modern cars and that take driving safety to a new level.
Traffic sign reading system
Virtually all manufacturers incorporate in their latest models a remote recognition system for traffic signs, so that the car interprets them and adapts its operation to the circumstances. Often offered in combination with adaptive cruise control systems.
Involuntary lane change notice
The system alerts the driver when the driver inadvertently leaves the path of the lane in which he is driving and invades an adjacent lane without signaling it. This system saves lives because it prevents the driver from invading the opposite lane on, for example, a secondary road, and the acoustic warning system is sufficient to alert the driver instantly.
The active suspension is responsible for independently managing and controlling the damping on each of the wheels. The objective: to maximize the contact of the tire with the road at all times, improving the stability and grip of the car, regardless of the floor. If we look closely, the importance of the tires being in contact with the ground and not skidding is crucial, and several of the most popular safety systems are designed for this.
The system works from the data collected by various sets of sensors (on wheels and shock absorbers, gyroscopic sensors) and controls the shock absorbers (with pneumatic or hydraulic systems inside), whose function is to vary the hardness of the shock absorber.
Every driver will know that it is a big problem when traveling on the motorway or highway and, before a maneuver such as overtaking, you have a completely blind rearview zone. In very particular cases it may be that, when deciding to change lanes, there is just a vehicle in that blind spot. It is at these moments where the detection system works, which by means of light signals indicates that another vehicle is behind ours although we cannot see it, avoiding the probable collision.
Emergency braking assistance
The emergency braking assistance system is quite simple to understand. In collaboration with ABS, the system detects when we are carrying out emergency braking (due to the speed at which we release the accelerator to fully depress the brake, for example), and makes the necessary calculations to exert the greatest possible stopping power at every moment.
This measure, aimed at reducing pedestrian accidents, is capable of detecting if any pedestrian crosses the car’s path, to which it responds with emergency braking to avoid being run over, thus helping to save many lives, especially in cities and areas where high population density and circulation coexist.
This system, with the help of sensors and radars (the same as the parking sensors), calculates the environment of the vehicle, thus allowing it to calculate the optimal safety distances at all times and the car to automatically adapt to traffic circumstances, avoiding mostly range collisions.
Also, the new rear-view mirrors by the camera are condemning the life of traditional mirrors. In addition to the mirrors that automatically eliminate reflections, there are also the mirrors that are actually high-resolution screens that inform what is happening behind the vehicle but with the advantage of eliminating blind spots.
Systems have also been developed to automatically detect signs of driver fatigue or fatigue, which scan features and movements of the steering wheel to determine if you are tired to drive, thereby issuing a warning signal that recommends taking a break.
The constant technological evolution in the steering and suspension systems has currently made elements as advanced as electronic power steering increasingly common in production vehicles.
So, if today these systems can operate autonomously during maneuvers such as parking, and there are adaptive suspension systems to achieve the best result in each terrain condition or type of driving… what is the next step?
Advances in management systems
As for the improvements related to the steering of the cars, we have seen an evolution that takes us from the traditional mechanical steering, hydraulic steering or electro-hydraulic steering, to end in the current electric steering, where despite all the electronic management, it continues There is a mechanical connection between the steering wheel and the steering rack, something that disappears in the Steer-by-wire direction.
This technology, in which the electronics gain weight over the mechanical parts, is already common in the acceleration system, where we did not find the gas cable, which traditionally linked the pedal with the throttle or the injection pump. Thus, at present, the cable has disappeared and in its place are angular sensors that measure the position of the pedal; This information is received by a processor, which opens the throttle valve by means of an actuator motor, or sends a signal to the injection computer (in the case of Diesel).
Going back to advances in direction, the sensors on the steering wheel measure movements by the driver. This information is sent to one or up to three processors, which control actuators in the direction in order to maintain the direction of the vehicle in accordance with the movements of the driver, eliminating the mechanical connection between steering wheel and rack, generating greater performance, automation, comfort, and better optimization of space.
To ensure the safety of these systems, which are completely dependent on electronic management, up to three processors are used in vehicles that use this technology, and they are also provided with a clutch that will link the steering wheel with the rack in the event that detects any error or fault in the system.
Advances in suspension systems
As far as suspension is concerned, adaptive suspension systems and roll control systems have been vastly improved in recent years. Thus, the pneumatic systems have evolved to the point of converting the car into an SUV or sports car, increasing or decreasing the ground clearance as well as the suspension setting at the driver’s discretion. In automatic mode, the same system is in charge of “reading” the road to detect irregularities and thus anticipate and adapt to circumstances. Radars located in the front of the vehicle send the readings of the pavement to the suspension calculator, which determines, according to the programmed parameters, the best instantaneous suspension configuration.
Also, magnetic suspensions, as they are popularly known, are gaining ground. These systems consist of shock absorbers filled with ferrofluid, which, when subjected to a magnetic load, varies its density, thus varying the behavior of the shock absorber. The different sensors of the vehicle are in charge of giving the necessary information to the computer so that it determines the magnetic load to which the ferrofluids of the shock absorbers must be subjected, in order to instantly adapt the behavior of the car suspension.
As for the active roll control, systems similar to those previously described are applied to counteract as much as possible the role of the body with respect to the ground. These systems harden or soften the spheres or stabilizer dampers on the opposite side to which the curve is traced, thus compensating for annoying rocking and achieving greater comfort and performance.
The tips made by experts, who explains how we should perform the cleaning of our car’s engine, where to have more caution and the benefits of having every mechanical component clean.
The cleaning of the engine is divided into several steps. If you follow them with caution, you will get a propeller with a new appearance, thus avoiding corrosion or any other problem that may arise due to dirt. There is also a special emphasis on the type of car, differentiating between the types of engines since the coatings and the parts in the air vary from one to another. These tips are linked to those of cleaning the upholstery, and the keys to wash the car correctly, with which you will have the car as new.
Step 1: Do not scratch the car during cleaning
The first recommendation is to cover with a towel or rag the areas of the car that we will support during cleaning, to avoid scratching the car with the belt or anything else.
Step 2: Check the motor temperature
It must be checked if the engine is cold, warm or hot. In most cases the logical thing is to clean the engine at a temperature between cold and warm, but in others it is advisable to clean it with the hottest engine. This case would be if the engine takes a lot without cleaning or accumulates much dirt. The higher the temperature, the easier it will be for the dirt to dissipate.
Once the temperature has been checked, a pressurized air machine can be used to remove the dirt that remains in the body covered by the hood. Normally these areas fill with leaves of the trees and take a lot of dust, so that the pressure air in those nooks and crannies is the best solution.
Step 3: Waterproof the delicate areas of the engine
This step is one of the most important to avoid that a simple cleaning becomes a breakdown. We must cover with plastic and help us with insulating tape to waterproof well the areas of the engine that can be affected badly by water.
All electrical components, battery, distributor, carburetors, filters … must be covered with plastic so that the water never reaches them. If this happens it can lead to a fault for the motor. We must also take care to remove greases from the areas where they are needed.
Step 4: Wet the engine without water under pressure
In this step we must wet the engine in a smooth way and spread over all areas.
Step 5: Apply a multi-purpose cleaner
Once the entire engine is wet, we can apply a multi-purpose cleaner, and with the help of a brush start distributing and cleaning the entire engine. It is important to distribute the entire cleaner before it evaporates or dries on any part, working all the time with the wet motor. For less accessible areas it is recommended that we use smaller brushes and thus reach any side.
Once we have done everything, we will have to wet everything again to finish cleaning the engine.
Step 6: Drying the motor
Now it would be time to dry the engine, which can be done with air or with simple towels, making sure that everything is dry.
Step 7: Remove the plastics that we put
It is time to remove all the plastic with which we waterproof the areas critical to the water, taking special care to remove them in not spilling the water that remains on them. It would be a pity that after cleaning and good insulation of these areas, water was dropped on some unwanted part when removing them.
It would be convenient to pass a towel to make sure everything is dry, and so the water does not reach any of these areas once the plastics have been removed.
Step 8: Polish plastics and wait to start the engine
Once dry everything can be used to pass some polish to the areas with plastics, so that everything is shinier after cleaning.
In many cases it is advisable to wait a couple of hours after cleaning to restart the engine. After that time, it is advisable to start the car and leave it on for two or three minutes, watching and hearing the engine to know if there is any noise or something that is not correct after cleaning.
At this point you will have the engine shining as the first day, safe from corrosion, avoiding breakdowns, and therefore a safer and more reliable car.
We know that many of you are crazy about your cars and want to take care of them every day more, in order to have a nice car at the same time as the day in all aspects of mechanics and safety.
The market is in good health and, although the WLTP will arrive in September and will be a big challenge for dealers and manufacturers, according to experts, it will continue to grow.
In the Spanish market, the SUVs have a great part of the responsibility of the success, although the king is still the Lion, the compact one of Seat and the utilitarian also tread very strong. These are the 10 most sold cars in 2018 and their prices.
The León is the favorite car of the Spaniards, betting on it 21,204 times this 2018. Its arguments are an attractive design, several levels of equipment to adapt to any customer, sports versions such as the FR and the Cupra, an efficient mechanical offer and with low consumption and a reasonable price range that starts from the 18,270 euros of version 1.2 TSI of 110 HP with Reference finish, up to 35,970 of Leon Cupra of 300 HP with DSG change. For the most demanding there is the version Cupra R, limited series, 310 hp and DSG exchange for 46,375 euros.
The Ibiza copies the formula of the success of its bigger brother on a smaller scale and with a more contained price. It is a very practical car for its size and very interesting for its quality and its equipment, in addition to its levels of finish and versions. 19,519 people bought a car that starts at 13,560 euros of its most basic version, up to 21,250 of the model with a 1.6 TDI engine of 95 HP with DSG change and Excellence finish. For lovers of sportsmanship, the Ibiza FR with 150 hp TSI 1.5 engine will let you discover how ferocious an Ibiza can be for 19,620 Euros.
The first brother of the Seat Ibiza, with which he shares a platform, the German compact was the target of 17,183 buyers, who bet on the effectiveness and quality that all Volkswagens promise. With a bet similar to that of the Ibiza, its price range rises from 12,800 Euros of the Polo Edition 1.0 of 65 hp, to 24,305 of the radical Polo GTI with 2.0 TSI engine and 200 hp, a power that can move its little more of 1,300 kilos in an incredible way. For 17,680 Euros a hybrid version of gas and gasoline of 90 HP of power is offered.
There are always representatives of Dacia among the best sellers. 16,728 people went in search of a Sandero during the first semester of this year. Its main coat is a considerable level of equipment for 9,745 Euros. Its most expensive version starts at 12,830 Euros.
The most famous Volkswagen vehicle was purchased by 16,551 people. Its great reputation, quality, and finishes make it an object of desire of many people. 18,635 Euros costs its most affordable version, 110 hp with 1.0 TSI engine, and 34,325 Euros variant GTI with a 2.0 TSI 230 hp.
Citroën offers comfort and safety in its entire offer, and with each model, they improve these sections. That’s what 16,385 people sought when they bought the French compact, whose two versions, 99 hp diesel and 110 hp gasoline, start at 15,590 Euros.
The first SUV on the list, and unique, is the Qashqai, the Nissan SUV. The 15,949 buyers found themselves with an all-around reference in the market. The Qashqai is available from 22,000 Euros in its version of 116 hp power, a price that can rise to 32,000 Euros with its variant of 163 hp.
It was the big surprise of the market in Spain and it was even the best sold in the country in March. The most classic Fiat fell in love with 15,925 people, who took an urban of 12,510 euros in its most basic version. The top of the range, with a 95 HP Multijet engine, costs 18,310 euros.
The Clio has always been very popular in the market, where it directly rivals the Polo and the Ibiza. His proposal, which convinced 15,708 interested, is to offer a 1.2 engine 73 hp for 12,095 Euros. Although the most demanding will find a very playful variant in the Clio Renault Sport Trophy Energy for 24,920 Euros, which will offer 220 hp.
With a proposal very similar to the Golf and the Lion, its great rivals, 15,155 people opted for the French compact, which starts, in its version of 101 HP, of 17,152 Euros. For 31,900 Euros, action lovers will find in the Megane RS, a great option, thanks to the 280 hp delivered and its aggressive image.
Tips and Tricks to Clean Your Car
In the world there are two kinds of people: those who wash the car every week and those who wash it once every two or three months – and give thanks. However, identify yourself with the first or second group, Detail King brings you some tricks to keep your car clean as long as you cannot (or want to) take it to the car wash. So do not hesitate to follow these simple tips.
- Clean up useless objects
Surely, if you enter your vehicle willing to take out things you do not need, you will end up filling a good bag. And is that we usually accumulate debris in the glove compartment or in any other nook of the car. By removing all these things that you do not need, the feeling of cleanliness will increase considerably.
- Shake the carpets
The carpets that cover the floor of our car look like a dirt magnet. Sand, mud and even moisture pass from our shoes to carpets, so pulling them out and shaking them against the outside floor is always a good idea.
Pass a vacuum inside the car, both carpets and seats; often help avoid the feeling of dirt and odors that may accumulate in the interior of the vehicle.
- Buy an air freshener
Placing an air freshener in the car is always a good idea, because entering it and smelling it well will help create a clean and relaxed atmosphere, creating a feeling of absolute freshness.
- Use a cloth
Sometimes, when it costs to demist the glasses of the car, we help with the hand to do it faster. Error. In case of rain or temperature drops, the best option is to help with a rag to improve the vision without dirtying the moon. And, of course, nothing to do drawings in the crystals, although sometimes it is difficult to leave aside our most childish part.
- Do not eat inside the car
It is essential that you avoid consuming food that can fall or drinks that can spill its liquid inside the vehicle, causing stains difficult to eliminate. In addition, the smell will also be impregnated in the car. Tobacco smoke will also act in the same way.
You arrive at the gas station and while you are refueling you notice the prohibition signs. And you think, it’s obviously dangerous to smoke from contact with high-flammability substances. But, why is it prohibited to use the mobile phone with the vehicle stopped at the gas station? Can it also cause a fire?
And then you think if you remember any case in which a gas station has exploded by the use of the mobile phone. You search the internet, and you get supposedly real cases of portals of very dubious credibility. Therefore, you ask yourself: will not it be an urban myth that mobile waves are capable of creating an explosion?
What science says?
Here is the answer: Yes, it’s an urban myth. Or rather, a yes with very specific characteristics.
As confirmed by the scientific community (and common sense) to produce a reaction that leads to ignition, it is necessary to give a spark that comes in contact with flammable substances. More specifically, with the steam emitted by gasoline mixed with air.
Therefore, the radiation emitted by the mobiles is not capable of causing this reaction. The odds of this happening, while not zero, are tiny. It would be dangerous, for example, if we had problems with the battery and that sparks flew from it. In that case, the mobile itself would be very dangerous. But if this is not the case, carry it in your pocket and call you while you are refueling will not make the gas station jump through the air.
To make you more relaxed, the Mythbusters program, known in our country as Mythbusters , conducted an experiment to check what happened if you used your phone at a gas station. Spoiler alert: Nothing .
The real danger: static electricity
It is curious that despite being repeatedly convinced of the danger of using a mobile phone, many do not know that the real danger we must know is the effect of static electricity. This is capable of causing an electric shock coming into contact with sufficient intensity can cause a reaction with the air and flammable substances contained in it.
While the chances of this happening, and in general that a gas station is set on fire, are very low, they are already greater than that caused by the radiation emitted by a mobile phone.
Therefore, it is recommended that when leaving to refuel, before touching the mouth of the tank, touch for a few seconds a metal part like the roof of the car. This way we will release part of the static electricity contained in us.
Summer is approaching and we are already having the first days with an overwhelming heat, with thermometers marking temperatures above 30 degrees. In addition to protecting your car from the sun and monitoring the problems with air conditioning, there are also tricks for the air conditioning to cool properly without involving a greater expenditure of fuel, as well as to extend its life and start to give failures at the most inappropriate moment and finish with the cabin turned into a furnace.
And is that air conditioning affects the consumption of the vehicle. While it is on, a compressor sucks the refrigerant gas and passes it to a condenser, where it returns to liquid state in a radiator… until the expansion valve, where it goes back to gas and cools down. After cooling the air, it passes thanks to a fan through the grilles of the dashboard aerators … and back to start.
All this process of removing heat from the air by mechanical processes (drawing air from the outside or recalculating the passenger compartment) spends energy, which comes from the car engine, which must make more effort : in addition to moving the vehicle, the engine You must operate the compressor. This extra effort translates into an increase in consumption between 5 and 20% (a few tenths in consumption, although it varies depending on the type of car).
And yes, benefits are lost, but you will only notice it in cars with small engines and demanding a lot of air conditioning. It is also true that some modern vehicles choose to disconnect the air conditioner if the pedal is pressed fully, so as not to compromise safety by demanding maximum power.
It is obvious that the more we try to lower the interior temperature, it will cost more energy (fuel in this case), to reach it. Therefore, using tricks to cool a car quickly can save some fuel.
Do you get to the car and discover that it is like an oven? To help the air conditioning to work, it is ideal that during the first minutes circulating proceed to open the window a little. Yes, at the same time you turn on the air conditioner. As hot air weighs less than cold, it tends to go up. That way you help it to go away and be replaced by the cold more quickly. After a while, you can proceed to close them.
In our tips to spend less fuel we already tell you that lowering the windows of the car worsens aerodynamics. That will make the car spend more … but that aerodynamic loss is not too big if the speed is low. According to several studies, the critical moment is at 80-90 km / h (from there, the air that enters “slows down” the car.) Hence, in urban journeys at a lower speed, you spend less fuel with the down windows that use background air conditioning to cool the car.
Sometimes, when the heat is a lot, lowering the windows is not enough to guarantee a comfortable temperature … but opening them will renew the hot air of the car, lowering a few degrees to the passenger compartment and making the compressor work less … spending less fuel.
Have you used it in winter?
Like any component in the car, getting it to work regularly is a guarantee that it will work when needed. So do not hesitate to use it for actions like demisting the crystals in winter. In addition to gaining security (it is much faster to gain visibility), you ensure that it is not damaged by lack of use.
Do not force it
To prevent the air conditioning from spoiling, it is also vital to avoid working at maximum power. In this sense, remember the first two points to lower the temperature of the passenger compartment before starting the road … and once underway, be rational with its use. Nor do you have to freeze. The ideal temperature inside the car should be around 22 degrees. Anything lower than that temperature is an unnecessary expense of fuel.
The cars of today do not suffer as before the problems of starting in cold, but in New Zealand a good part of the car park is more than 8 years old and suffers in the cold winters. First of all, if a car is in perfect condition should not have problems at the time of starting but the fact is that the lack of fine tuning plays tricks on many occasions.
Recently we talked about some solutions so that winter does not spoil your car and today we will focus on the moment of the start. Because if the maintenance of the car has not been exemplary and the problems with the start-up appear, we leave you some tips that can help and that can be applied to the vast majority of vehicles.
It goes without saying that if the car is indoors you have many more chances of starting your car without problems, although this is not always possible. In the event that you have to park on the street, it is best to find a place not very exposed, that is sheltered from the wind and if possible under the street lighting, that something can help.
The Car battery is one of the elements that suffers more problems in winter . A very cold battery has much less starting power than a hotter one. So, a good hot and dry cloth on the battery a few minutes before starting can be an interesting first option. In the event that the battery is broken, we share these tips to buy a new one.
For extreme cases, it is important to know that less viscous (more fluid) oil facilitates cold start. This practice is more widespread in competition engines taking into account the temperature of the place where it runs. Another option is multigrade oils, capable of achieving a better viscosity to start without problems in winter.
In diesel cars, you can operate heaters a couple of times; Even if you abuse a little battery, the starter must surely work less. It will always be necessary to wait until the heater warning light goes off (in the form of a spring), to try again.
In gasoline engines taking good care of the spark plugs should not have problems with the start. This element serves to produce the spark that ignites the engine and if its state is not correct it is likely that there are problems to start. In a gasoline car will have the advantage of not needing as much time at idle as in a diesel.
If it is a carburetion engine you can try to take two or three quick and hard strokes before hitting the contact. You will help to prime the carburetor and facilitate the start.
Periodically change the air filters and fuel filters to facilitate starting. Some time ago we talked about the different filters that cars have and some keys for their correct maintenance. In fact, the particulate filter in diesel cars is one of the most common problems.
If you cannot start the car you just have to look for a small fall in the street and leave the car in neutral, with the inertia you will get speed and it is at that moment when you put the second gear and the car should start.
