AI Technical Summary
Existing motor pulse width modulation control methods only consider the speed and torque of the motor, which cannot meet the requirements of the vehicle's NVH, electronic component lifespan and handling performance, resulting in lower overall vehicle efficiency, handling and comfort.
Different pulse width modulation strategies, such as DPWM, CPWM and ACPWM, are adopted according to different motor operating modes to optimize current harmonics and switching frequency, so as to meet the different needs of the whole vehicle and improve the efficiency, handling and comfort of the whole vehicle.
By adjusting the pulse width modulation strategy, optimizing current harmonics and switching frequency, the vehicle's range, torque quality, and NVH performance were improved, motor switching losses were reduced, and the vehicle's handling and comfort were enhanced.
