The invention provides a vehicle sensor fault diagnosis method and a vehicle control method, and the method comprises the steps: obtaining a measurement value of at least one target sensor on a vehicle; observing the measured value of at least one target sensor by using an observer to obtain a corresponding estimated value; calculating a sequence standard deviation of measurement values of at least one target sensor; calculating a first residual sequence between the estimated value of at least one target sensor and the corresponding measured value; and performing fault diagnosis on the corresponding target sensor according to the sequence standard deviation and the first residual sequence corresponding to the target sensor to obtain a fault degree. According to the embodiment of the invention, the fault degree of the vehicle sensor can be diagnosed.
本申请提供一种车辆传感器故障诊断方法和车辆控制方法,其中,车辆传感器故障诊断方法包括:获取车辆上至少一个目标传感器的测量值;采用观测器对至少一个所述目标传感器的测量值进行观测,得到对应的估计值;计算至少一个所述目标传感器的测量值的序列标准差;以及,计算至少一个所述目标传感器的估计值与对应测量值之间的第一残差序列;根据所述目标传感器对应的序列标准差和第一残差序列,对对应的目标传感器进行故障诊断,得到故障程度。本发明实施例可以对车辆传感器的故障程度进行诊断。
