The invention relates to the technical field of vehicles, and provides a vehicle automatic driving safety control method and system. A working micro-control unit in the system determines a vehicle motion preliminary decision based on first sensing data and vehicle driving planning information; based on the working state of the system-on-chip and the working state of the guarding micro-control unit, determining an allowable output type of a vehicle motion preliminary decision, and obtaining a vehicle motion control instruction; and then, the guarding micro-control unit determines the vehicle driving safety state based on the current vehicle driving information, the first sensing data, the vehicle motion control instruction and the working state of the working micro-control unit, and if the vehicle driving safety state is dangerous, a braking instruction is output. The cost increase is small, more motion decision sets are realized, and the driving safety and the function reliability are improved. The working state of the working micro-control unit system is monitored, a certain decision-making ability is still kept in case of safety failure, and soft exit of the automatic driving function is realized.
本申请涉及车辆技术领域,提出了一种车辆自动驾驶安全控制方法及系统,该系统中工作微控制单元基于第一感知数据和车辆行驶规划信息确定车辆运动初步决策,基于片上系统工作状态和守护微控制单元工作状态确定车辆运动初步决策的允许输出种类,得到车辆运动控制指令,然后通过守护微控制单元基于当前车辆行驶信息、第一感知数据、车辆运动控制指令和工作微控制单元工作状态确定车辆行驶安全状态,若车辆行驶安全状态为危险,输出刹车指令。在成本增加较小,实现了更多的运动决策集,提升了驾驶安全性和功能可靠性。监测工作微控制单元系统的工作状态,在安全失败仍然保持一定的决策能力,实现自动驾驶功能的软退出。
