A Control System of Vehicle Rear-end Anti-collision

This paper puts forward a control method of vehicle rear-end anti-collision security system from the point of view of ensuring the traffic safety. The system makes full use of the electromagnetic devices which are installed on the trail of leading vehicle and the head of following vehicle. It uses the principle of electromagnetic repulsion of the same. When the leading vehicle suddenly slows down or has an emergency stopping, the devices open at the same time to increase the deceleration of following vehicle to set up an automatic auxiliary braking system. The purpose of the method is to avoid the driver´s reaction delay and ensure the car safety immediately. Meanwhile, it can improve the efficiency of deceleration. This paper analyses the feasibility of the method from two aspects: safety distance and deceleration efficiency.
