The invention relates to a redundancy control emergency braking method and system, and relates to the technical field of vehicle braking, and the redundancy control emergency braking method comprises the following steps: detecting a front-end obstacle of a target vehicle according to a preset detection time interval, and obtaining a corresponding obstacle spacing distance and a current obstacle speed; when the barrier spacing distance is smaller than a preset maximum safe car-following distance first threshold value, comparing the barrier spacing distance obtained by the next detection of the barrier sensing module at the next moment with a preset maximum safe car-following distance second threshold value; and when the barrier spacing distance at the next moment is smaller than a second threshold value of the maximum safe car following distance, generating an emergency braking instruction. The obstacle at the front end of the vehicle is detected, emergency braking with a redundancy control function is carried out on the vehicle in combination with different preset threshold values of the maximum safe vehicle following distance, the safety performance of the vehicle is improved to a certain degree, and the reliability of the emergency braking function is improved.
本申请涉及一种冗余控制的紧急刹车方法及系统,涉及车辆制动技术领域,该冗余控制的紧急刹车方法包括以下步骤:按照预设的探测时间间隔对目标车辆的前端障碍物进行探测,并获得对应的障碍物间隔距离以及障碍物当前速度;当障碍物间隔距离小于预设的最大安全跟车距离第一阈值时,将障碍感知模块下一次探测获得的后一时刻障碍物间隔距离与预设的最大安全跟车距离第二阈值进行比对,当后一时刻障碍物间隔距离小于最大安全跟车距离第二阈值时生成紧急刹车指令。本申请对车辆前端障碍物进行探测,结合预设的最大安全跟车距离的不同阈值,对车辆进行具有冗余控制功能的紧急制动,在一定程度上提高车辆的安全性能,提高紧急制动功能的可靠性。
