基于电控液压制动装置的车辆主动报警/避撞系统

为预防道路尾随相撞事故,开发了一种基于电控液压制动装置的车辆前向报警/避撞系统。该系统根据前方车辆和自车的运动状态,基于碰撞时间实时判断尾随相撞危险度。在危险情况下,系统通过视听觉报警为驾驶员提供警示,并以电控液压制动的方式实现车辆的主动避撞。利用电控液压制动装置搭建了实验平台,对制动压力控制效果进行了验证。将系统安装于试验样车,实车试验结果表明,该系统能为驾驶员提供分级碰撞报警警示和制动辅助,以提高行车安全性。

Vehicle collision warning and avoidance system based on electronic hydraulic brake device

A forward vehicle collision warning and avoidance system was proposed based on the electronic hydraulic brake device to prevent the rear-end collision.The system real-timely judges the dangerous level of rear-end collision with a time-to-collision algorithm based on the running situations of the front vehicle and this vehicle.When the collision possibility is detected,the system warns the driver with vision and hearing warnings and achieves the vehicle active collision avoidance by the electronic hydraulic brake.An experiment platform was established on a real vehicle to verify the brake pressure control effect.Introducing the system in a test vehicle,the test results show that the system provided timely the stepped collision warning and the brake assistance,enhancing the vehicle driving safety.
