Vehicle anti-collision system and vehicle anti-collision method

Abstract

A vehicle anti-collision system comprises a vehicle speed sensing unit, a distance measuring sensing unit, an electronic parking brake unit and a control unit. The vehicle speed sensing unit is used for sensing the speed of a vehicle; the distance measuring sensing unit is used for sensing the relevant distance from an obstacle around the vehicle to the vehicle; the control unit is used for calculating a period of time in which the vehicle will collide with the obstacle according to the speed of the vehicle, and the relevant distance from the obstacle to the vehicle, and controlling the electronic parking brake unit to provide brake assistance for the vehicle when the collision duration is not longer than a period of brake time. The electronic parking brake unit is arranged and matched with the vehicle speed sensing unit and the distance measuring sensing unit, brake assistance can be executed to avoid the vehicle collision situation at the condition of low-speed reversing or parking, and the arrangement cost of the system can be reduced.

Description

technical field [0001] The invention relates to an anti-collision system and method, in particular to a vehicle anti-collision system and method. Background technique [0002] When the driver sits inside the car, due to the limited view angle of the human eye, it is impossible to take into account all directions at the same time, especially when parking and reversing, often because the driver does not pay attention or the sight cannot be taken into account at the same time, it is easy to have a collision. Therefore, how to prevent vehicle collisions is one of the main research goals of manufacturers. [0003] The early vehicle collision avoidance technology is passive safety warning. When the vehicle is too close to an obstacle, it will generate a warning to remind the driver to pay attention. At present, it has evolved into active automatic emergency braking, and most of them use hydraulic brake control system or electronic stability system ( Electronic Stability Program, ...

[0003] The early vehicle collision avoidance technology is passive safety warning. When the vehicle is too close to an obstacle, it will generate a warning to remind the driver to pay attention. At present, it has evolved into active automatic emergency braking, and most of them use hydraulic brake control system or electronic stability system ( Electronic Stability Program, abbreviated as ESP, also known as electronic body stabilization system) is used with a distance sensor. However, whether it is a hydraulic brake control system or an electronic stability system, both have problems of high cost and complicated control methods
