A power distribution system is provided that ensures safe operation of an automobile in an autonomous mode. The system includes a plurality of power rails including a pair of safety critical power rails. Safety switches, vehicle sensors (e.g., vehicle position and obstacle sensors), vehicle actuators (e.g., brake and steering actuators), and autonomous control units are associated with each safety critical power rail. If a fault is detected during vehicle initialization or general operation, the safety switch in which the fault is detected opens and the particular power rail is disconnected from the general power rail and the remaining safety critical power rails. The remaining safety critical power rails can then provide power to a sufficient number of sensors, actuators, and controllers to allow the vehicle to safely and autonomously complete an emergency stop at the roadside.

    提供了一种配电系统,其确保汽车能够在自主模式下安全运行。该系统包括多个电力轨,其包括一对安全关键电力轨。安全开关、车辆传感器(例如车辆位置和障碍物传感器)、车辆致动器(例如制动和转向致动器)和自主控制单元与每个安全关键电力轨相关。如果在车辆初始化或一般操作期间检测到故障,检测到故障的安全开关打开,并且该特定电力轨与通用电力轨以及其余安全关键电力轨断开。然后,其余安全关键电力轨能够向足够数量的传感器、致动器和控制器提供电力,以允许汽车安全且自主地完成在路边的紧急停靠。
