The invention discloses a vehicle speed signal processing method and device, a vehicle control unit and a vehicle, and the method comprises the steps: receiving a vehicle speed processing instruction of the vehicle; when it is detected that the vehicle speed sensor of the vehicle fails, whether related signals sent by electronic components, related to the vehicle speed, of the vehicle are lost or invalid or not is judged according to the preset priority; and if the related signal of the electronic component with the current priority is valid, generating a whole vehicle speed signal by the related signal. Therefore, the problem that in the prior art, after the vehicle speed sensor and the wheel speed sensor fail at the same time, the vehicle cannot obtain the vehicle speed signal replacement value, so that the vehicle runs in the fault state, and traffic accidents are likely to happen is solved, and the safety of the vehicle is effectively improved.

    本申请公开了一种车速信号处理方法、装置、整车控制器及汽车,其中,方法包括:接收汽车的车速处理指令;在检测到汽车的车速传感器失效时,根据预设优先级判断汽车的与车速相关的电子部件发送的相关信号是否丢失或无效;若当前优先级的电子部件的相关信号有效,则由相关信号生成整车车速信号。由此,解决了相关技术中车速传感器和轮速传感器同时失效后车辆将无法获得车速信号替代值,导致车辆在故障状态下行车,极易发生交通事故的问题,有效提高车辆的安全性。
