The invention relates to a fault diagnosis and fault tolerant control method for automobile electronic stable control system sensors. The method includes the steps that a fault diagnosis system of the automobile electronic stable control system sensors is arranged; a steering wheel turn angle threshold value, a yaw velocity threshold value, a lateral acceleration threshold value and a time threshold value are set; a steering wheel turn angle actual value is measured, a steering wheel turn angle estimation value is estimated, and a steering wheel turn angle residual error is calculated; the steering wheel turn angle residual error and the steering wheel turn angle threshold value are compared to determine whether a fault occurs on the steering wheel turn angle sensor. A yaw velocity actual value is measured, a yaw velocity estimation value is estimated, and a yaw velocity residual error and the yaw velocity threshold value are compared to determine whether a fault occurs on the yaw velocity sensor. A lateral acceleration actual value is measured, a lateral acceleration estimation value is estimated, and a lateral acceleration residual error and the lateral acceleration threshold value are compared to determine whether a fault occurs on the lateral acceleration sensor. The method can be widely applied to automobile sensor fault diagnosis and fault tolerant control.
