The invention provides an automatic driving redundant power supply system and a vehicle automatic driving control method and device, and relates to the technical field of automatic driving. According to the specific scheme, the automatic driving redundant power supply system comprises a main power supply branch and a first redundant power supply branch, and the main power supply branch and the first redundant power supply branch are connected in parallel and are both connected with a vehicle-mounted power supply and a vehicle body drive-by-wire execution unit; the automatic driving redundant power supply system further comprises a second redundant power supply branch circuit, and the second redundant power supply branch circuit is provided with a standby power supply unit and a safety redundant drive-by-wire execution unit. And under the condition that the vehicle-mounted power supply fails, the vehicle body drive-by-wire execution unit is controlled through the second redundant power supply branch. According to the scheme, through the design that the second redundant power supply branch is added to the automatic driving redundant power supply system, when the vehicle-mounted power supply fails, the vehicle body drive-by-wire execution unit is controlled through the second redundant power supply branch, the failure probability of the automatic driving vehicle can be effectively reduced, and the safety of the automatic driving vehicle is improved.

    本公开提供了一种自动驾驶冗余供电系统、车辆自动驾驶控制方法和装置,涉及自动驾驶技术领域。具体方案:自动驾驶冗余供电系统包括主供电支路和第一冗余供电支路,主供电支路和第一冗余供电支路并联,且均与车载供电电源和车身线控执行单元连接;自动驾驶冗余供电系统还包括:第二冗余供电支路,第二冗余供电支路上设有备用电源单元和安全冗余线控执行单元;在车载供电电源失效的情况下,通过第二冗余供电支路控制车身线控执行单元。本公开的方案,通过为自动驾驶冗余供电系统添加第二冗余供电支路的设计,在车载供电电源失效时,通过第二冗余供电支路控制车身线控执行单元,能够有效降低自动驾驶车辆的失效概率,提高自动驾驶车辆的安全性。
