Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

[0023] Such as figure 1 The anti-rear collision safety system with early warning and protection functions shown includes a radar controller unit 1, a light controller unit 2, a hazard warning light 3, a human-computer interaction unit 4, an active safety belt unit 5 and an active seat unit 6 . The radar controller unit 1 is respectively connected with the lighting controller unit 2 , the human-computer interaction unit 4 , the active safety belt unit 5 and the active seat unit 6 , and the lighting controller unit 2 is connected with the hazard warning light 3 .

[0024] The radar controller unit 1 is used to continuously detect the speed and distance of the rear vehicle relative to the vehicle, and calculate the pre-collision time TTC between the rear vehicle and the vehicle, and compare the pre-collision time TTC with the preset first collision time Tmax Compared with th...

Abstract

The invention discloses a rear-end collision preventing safety system and method with early warning and protecting functions. The system comprises a radar controller unit, a lamplight controller unit, a danger warning lamp, a man-machine interaction unit, an active safety belt unit and an active seat unit. The radar controller unit is connected with the lamplight controller unit, the man-machine interaction unit, the active safety belt unit and the active seat unit. The lamplight controller unit is connected with the danger warning lamp. By the adoption of the system and method, rear-end collisions can be reduced, and when a rear-end collision cannot be avoided, harm caused by the collision to a driver and passengers can be reduced.

Description

technical field [0001] The invention belongs to the safe driving technology of automobiles, and in particular relates to a rear-end collision prevention safety system and method with early warning and protection functions. Background technique [0002] With the continuous growth of car ownership, the importance of car safety issues to consumers is becoming more and more prominent. According to investigations, a considerable number of car accidents are caused by rear-end collisions, and most rear-end collisions are caused by the emergency braking of the vehicle in front. More and more cars are equipped with forward anti-collision systems. When the front anti-collision system sends an alarm, the driver of the vehicle will perform emergency braking within 1-2 seconds, which is very slow for the rear vehicles. Short, it is likely to cause the car to be rear-ended. If the car can send an alarm to the rear car in time before emergency braking, the driver of the rear vehicle can ...
