Backup method for chassis steering system of unmanned automotive

The invention discloses a backup method for a chassis steering system of an unmanned automotive. The backup method for the chassis steering system of the unmanned automotive comprises the steps of initialization, obtaining external information and intelligent decision, fault detection, steering system performance degradation, system execution control command and the like, so that backup work of avehicle steering system is realized, and occurrence of the phenomena of traffic accidents or traffic jams due to the immediate standstill of a vehicle after the vehicle steering system goes wrong is avoided. 本发明公开了种无人驾驶汽车底盘转向系统备份方法，包括：初始化、获取外部信息与智能决策、故障检测、转向系统性能降级以及系统执行控制指令等步骤，从而实现车辆转向系统的备份工作，防止车辆转向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。
