The invention discloses a vehicle speed signal diagnosis method, device and equipment and a storage medium. Comprising the steps that vehicle speed related signals of a current vehicle are obtained, and the vehicle speed related signals comprise a vehicle speed signal and an acceleration signal; generating an electrical fault diagnosis result according to the vehicle speed related signal; and when the electrical fault diagnosis result is normal diagnosis, generating a vehicle speed signal diagnosis result according to the vehicle speed related signal. The electrical fault diagnosis result is determined through the vehicle speed signal and the acceleration signal of the current vehicle, and when the electrical fault diagnosis result is normal, the vehicle speed signal diagnosis result is generated through the vehicle speed related signal, so that the rationality fault of the vehicle speed signal can be accurately diagnosed; the vehicle performance can be degraded to enter a relatively safe state, so that the safety of personnel and the vehicle is ensured, the application range is wider, and even if the vehicle is in a gear shifting process or in a tunnel or other places with weak GPS signals, diagnosis can be normally carried out without interruption.
本发明公开了一种车速信号诊断方法、装置、设备及存储介质。包括:获取当前车辆的车速相关信号,其中,车速相关信号包括车速信号和加速度信号;根据车速相关信号生成电气类故障诊断结果;当电气类故障诊断结果为诊断正常时,根据车速相关信号生成车速信号诊断结果。通过当前车辆的车速信号和加速度信号确定电气类故障诊断结果,当电气类故障诊断结果为诊断正常时,通过车速相关信号生成车速信号诊断结果,可以准确的诊断出车速信号的合理性故障,并且可以使车辆性能降级以进入一个相对安全的状态,进而保证人员、车辆的安全,并且适用范围更广,即便车辆处于换挡过程中或者处于隧道等GPS信号较弱的地方,诊断也能够正常进行,无需中断诊断。
