Title:
MOTOR POSITION SIGNAL FAULT DETERMINATION METHOD, DEVICE, SYSTEM, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/032380
Kind Code:
A1
Abstract:
A motor position signal fault determination method, a device, a system, and a vehicle. The motor position signal fault determination method provided by embodiments of the present disclosure comprises: acquiring an electric signal output by a position sensor, the position sensor being used for acquiring an angle of a motor; on the basis of the electric signal, calculating a first angle of the motor by using a first algorithm; on the basis of the electric signal, calculating a second angle of the motor by using a second algorithm; and when a difference between the first angle and the second angle is less than or equal to a preset value, determining that a position signal of the motor has no fault.
