  • Publication number: 20250132708
    Abstract: Provided are a method for determining a fault in a position signal of a motor, a device, a system, and a vehicle. According to embodiments of the present disclosure, the method for determining the fault in the position signal of the motor includes: acquiring an electrical signal outputted by a position sensor, the position sensor being configured to acquire an angle of the motor; calculating a first angle of the motor based on the electrical signal by using a first algorithm; calculating a second angle of the motor based on the electrical signal by using a second algorithm, and in response to a difference between the first angle and the second angle being smaller than or equal to a predetermined value, determining that there is a fault in the position signal of the motor.
