Title:
METHOD AND APPARATUS FOR DETERMINING POSITION ANGLE OF MOTOR, AND ELECTRONIC DEVICE AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/240917
Kind Code:
A1
Abstract:
The present disclosure relates to a method and apparatus for determining a position angle of a motor, and an electronic device and a vehicle. The method comprises: obtaining a resolver angle signal sampled by a motor in a current period, and obtaining a resolver angle signal, that is represented not to be interfered, located in a sampling period before the current period; determining, according to the change trend presented by all the obtained resolver angle signals, whether the resolver angle signal sampled in the current sampling period is interfered; and when it is determined that the resolver angle signal sampled in the current sampling period is interfered, determining a position angle of the motor in the current sampling period according to a first reference value and a second reference value. Filtering processing is not needed, the real-time performance of the resolver angle signal is ensured, and the problem that the control accuracy and stability of a vehicle system are affected by the resolver angle signal subjected to electromagnetic interference is solved.
