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.
