Pilotless automobile chassis power supply system backup method

The invention discloses a pilotless automobile chassis power supply system backup method which comprises the steps of initialization, acquisition of external information and intelligent decision making, fault detection, system performance reduction, control instruction execution of a system and the like. Accordingly, backup work of a vehicle power supply system is achieved, and the phenomenon is prevented that instant vehicle invalidation occurs after a vehicle power supply system goes wrong and accordingly traffic accidents or traffic jam is caused. 本发明公开了种无人驾驶汽车底盘供电系统备份方法，包括：初始化、获取外部信息与智能决策、故障检测、系统性能降级、系统执行控制指令等步骤，从而实现车辆供电系统的备份工作，防止车辆供电系统出现问题后车辆立即瘫痪，造成交通事故或交通拥堵的现象发生。
