Fault protection method, fault protection system and vehicle

The embodiment of the invention relates to a fault protection method, a fault protection system and a vehicle. The method comprises the following steps: performing fault detection in a formation automatic driving state; under the condition that a preset fault is detected, a main state machine is controlled to enter a fault protection degradation state from an automatic driving state, and a control line control chassis is controlled to execute side parking processing under the fault protection degradation state; wherein the preset fault comprises at least one of failure of an automatic driving controller and failure of a drive-by-wire chassis. By the adoption of the method, when the automatic driving system or the vehicle fails, safety measures can be provided so as to reduce risks caused by faults and failures. 本公开实施例涉及一种故障保护方法、故障保护系统和车辆。所述方法包括：在编队自动驾驶状态下，进行故障检测；在检测到预设故障的情况下，控制主状态机从自动驾驶状态进入故障保护降级状态，并在所述故障保护降级状态下控制线控底盘执行靠边停车处理；其中，所述预设故障包括自动驾驶控制器失效和线控底盘失效中的至少一种。采用本方法能够在自动驾驶系统或车辆在出现失效时，能够提供安全措施，以降低故障和失效导致的风险。
