Method and device for controlling rear-end collision of vehicles in time of tire burst

Abstract

The invention discloses a method and a device for controlling rear-end collision of vehicles in time of tire burst. The method includes: a rear vehicle detector detects, at certain time intervals, relative speed and relative distance L between a vehicle body and a rear vehicle as well as position coordinates of the rear vehicle corresponding to the vehicle body; a speed sensor detects the speed of the vehicle body, a transverse angular velocity sensor detects transverse angular velocity of the vehicle self, and a tire pressure sensor detects tire pressure; a controller sequentially calculates maximum deceleration that can be executed on different rear vehicles; according to maximum deceleration speed control, the controller controls the vehicle self to slow down within the maximum deceleration control speed through a vehicle power system and a brake producing device. By the method and the device, the vehicle self can be controlled to be braked to slow down in time of the tire burst according the speed of the same and the rear vehicle as well as the distance from the rear vehicle.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to a device capable of controlling the deceleration of the own vehicle in real time according to the relative speed, the relative distance and the change of the yaw angular velocity between the vehicle and the rear vehicle after the vehicle tire blows out. A car tire blowout anti-tail collision control method and control device for effectively preventing rear-end collisions of rear vehicles. Background technique [0002] With the development of electronic sensing technology and vehicle dynamic control technology, various active safety systems are being widely developed. Various active safety systems can be divided into two types of functions according to whether they intervene in driving: early warning functions and control functions. Among them, the vehicle tire blowout monitoring and control system (BMCS) is more common in the active safety system with control functions...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to overcome the fact that the vehicle tire blowout control device in the prior art cannot control the deceleration of the vehicle in real time according to the relative speed and relative distance between the vehicle and the vehicle behind. The lack of rear-end collision of the own car provides a car that can control the deceleration of the own car in real time according to the relative speed, relative distance and yaw angular velocity between the own car and the rear vehicle, and effectively prevent the rear-end collision of the rear vehicle.
