The invention provides a vehicle-mounted sensor signal validity judgment method and device, electronic equipment and a vehicle, after the vehicle is started and before the vehicle runs, a to-be-judged sensor carries out signal collection under the current situation of the vehicle to obtain a to-be-judged time domain signal, and the to-be-judged time domain signal is converted into a to-be-judged frequency domain signal. And extracting a target signal from the to-be-determined frequency domain signal, wherein the target signal has a matched frequency band with a pre-calibrated basic frequency band signal. As the scene corresponding to the calibration test is the same as the actual application scene in the scheme, the difference value between the target signal and the basic frequency band signal should be small theoretically. And if the difference value between the target signal and the basic frequency band signal is greater than a preset threshold value, the time domain signal to be judged can be determined to be an invalid value, and the validity of the vehicle-mounted sensor can be judged through the scheme.

    本申请提供了一种车载传感器信号有效性判定方法、装置、电子设备及车辆,车辆启动后行驶前,通过待判定传感器在车辆当前情形下进行信号采集得到待判定时域信号,并将待判定时域信号转换为待判定频域信号。从待判定频域信号中提取出目标信号,目标信号与预先标定得到的基础频段信号具有匹配的频段。因为标定试验对应的场景和本方案中的实际应用场景是相同的,所以理论上目标信号与基础频段信号之间的差异值应当较小。如果目标信号与基础频段信号的差异值大于预先规定好的设定阈值,则可以确定待判定时域信号为无效值,通过本方案可以对车载传感器的有效性进行判定。
