Preventive or preventive security systems are used extensively in modern vehicles. Major road companies are setting their own models for their own integrated development.
The Integrated Safety Warning System includes:
- Elements of vehicle passive safety (body design, bumper, belts and airbags, front panel members, head restraints, etc.);
- Electronic safety systems that assess the road situation and driver actions and shall be connected to the threat of an accident (cruise control, exchange rate stability system, emergency braking system).
The study of emergency road situations, drivers ' actions and consequences of accidents has inspired experts to new development of security systems. One such system was the post-crash braking system.
New developments
Studies of one of the biggest European auto clubs, the German ADAC, have shown that a quarter of all accidents do not end with one collision. After the first strike comes the next collision with a second, third car or an obstacle. This is because the driver is disoriented, too traumatized, or unconscious. He just can't stop at a time like this.
The German company Continental presented its new development called Post Crash Braking Technology (PCBT). It is an electronic security system that eliminates repeated collisions after the first strike, smoothly stopping the car. This development will complement the company's complex security system, Conti Guard, which was created by the company earlier.
Working principles
The main goal of the system is not to give a car that was already hit by the first strike and may have lost control, move on and make collisions.
The system is managed by an electronic control unit. She works in conjunction with other security systems in the car. The sensors and the transmitting devices are engaged in exchange rate and passive safety systems.
The system's passive safety sensors are triggered after the impact. The information that the collision occurred is transmitted to the exchange rate stability system. The exchange rate stability system forms control impulses that affect the valves of the braking system. The car's trajectory is stabilizing and the car stops. The system does not block the brakes, and the machine does not overdrive the brakes.
It is noteworthy that the system is included only in the event of a driver's inactivity. If the driver has not lost the ability to drive and presses the pedal, the system is not switched on. Not only does the brake, but also the accelerator monitor, because it is possible for the driver to manoeuvre. Also, control of the situation is returned to the driver if he started operating after the system has been powered on.
First application
The first car on which the system is used is the Volkswagen Golf 7. The presentation of the model took place in Berlin in September 2012 and the serial production started in 2013.
