Embodiment Construction

[0059] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0060] Such as figure 1 The illustrated embodiment is a car tire blowout prevention rear-end collision control device. The car is provided with a yaw rate sensor 1 and a vehicle speed sensor 2, including a tire pressure detection module 3 respectively arranged in each tire, which is arranged in the compartment The controller 4 and the first wireless transceiver module 5 for receiving tire pressure signals are arranged at the rear vehicle detector 6 at the rear of the compartment; the tire pressure detection module includes a microprocessor 7, a second wireless transceiver module 8 and a sensor module 9. The microprocessor is electrically connected to the second wireless transceiver module and the sensor module respectively; the controller is connected to the tire pressure detection module, the first wireless transceiver module, the vehicle spee...

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...
