Title:
MOTOR TORQUE ZERO-CROSSING PARAMETER PROCESSING METHOD AND SYSTEM, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/206074
Kind Code:
A1
Abstract:
The present application discloses a motor torque zero-crossing parameter processing method and system, and a vehicle. The motor torque zero-crossing parameter processing method comprises: determining that a torque zero-crossing process needs to be executed; determining preset environmental parameters, and determining fixed parameters and variable parameters of the torque zero-crossing process under the preset environmental parameters; respectively executing the torque zero-crossing process multiple times by using multiple variable parameters in a preset range of the variable parameters, obtaining evaluation parameters of the torque zero-crossing process executed each time, recording an optimal value among all the evaluation parameters, and using the variable parameter corresponding to the optimal value as an optimal parameter among the multiple variable parameters; and returning to execute the determination that a torque zero-crossing process needs to be executed, until the optimal parameter under all the preset environmental parameters is obtained.
