A vehicle rear collision avoidance control system and control method

Abstract

The invention discloses a vehicle rear-direction anti-collision control system. The system comprises an information acquisition module used for collecting the distance and relative speed between a current vehicle and a rear vehicle and the distance between the current vehicle and a front vehicle, an information processing module used for acquiring the information collected by the information acquisition module and judging whether the current vehicle has the rear-end risk due to the rear vehicle or not, an information output module used for sending early warning information when the current vehicle has the rear-end risk, an electronic throttle control device used for controlling vehicle acceleration, and a positioning module used for determining the position of the vehicle. Meanwhile, the invention further provides a vehicle rear-direction anti-collision control method.

Description

Technical field [0001] The invention belongs to the technical field of automobile anti-collision control, and particularly relates to an automobile backward anti-collision control system and control method. Background technique [0002] With the increase in car ownership, there are more and more cars on the road, and the corresponding car collision accidents will inevitably increase. Therefore, it is of great significance to study car anti-collision systems. [0003] At this stage, the anti-collision system is mainly researched on the forward anti-collision of automobiles. The backward anti-collision technology at this stage is mainly researched on backward warning, but there is no control of the vehicle, so that collision accidents are still prone to occur when the driver of the following vehicle does not react or does not see the warning device. Therefore, the present invention proposes A vehicle rearward collision avoidance control system that can warn the driver when the vehic...

AI Technical Summary

Problems solved by technology

The rearward collision prevention technology is mainly researched at the present stage on the rearward warning, but there is no control of the vehicle, so that the driver of the rear car is still prone to collision accidents when he does not react or sees the warning device, so the present invention proposes A car rearward anti-collision control system is developed, which can warn the driver when the rear car may collide with the front car and let the front car accelerate to keep a safe distance from the rear car, actively avoiding the accident of two cars colliding , if necessary, the rear of the front car will send a warning signal to remind the rear car to control the speed to prevent collision
