Abstract

The invention provides an electrically-driven active heating control method and equipment, and the method comprises the steps: obtaining motor parameters of a driving motor in an electrically-driven system, determining a target excitation current according to the motor parameters and a preset motor torque algorithm, and controlling the driving motor to emit heat under the effect of the target excitation current, the output torque of the driving motor meets a preset condition, and then the three-phase current of the driving motor is determined according to the target excitation current, the preset torque current and the current rotor position. The target excitation current is controlled through the preset motor torque algorithm, and the preset torque current is controlled, so that the three-phase current is redistributed, and the output torque of the motor is zero under the condition that the target excitation current and the preset torque current are not zero; therefore, the total heating power of the motor is improved.

Description

technical field [0001] The present application relates to the technical field of electric vehicle drive, and in particular, to a method and device for active heating control of an electric drive. Background technique [0002] Electric vehicles are powered by on-board power and use motors to drive the car. Electric vehicles have been developing rapidly and continuously around the world because of their obvious advantages of cleanliness and energy saving. However, the performance of electric vehicles is seriously attenuated in low temperature environment, which greatly affects the convenience of vehicle use. Therefore, a scheme of active heating of electric vehicle motors is proposed. [0003] In the prior art, by controlling the torque current to be zero in the parking condition to ensure that the output torque of the motor is zero, and at the same time controlling the excitation current to be non-zero, the excitation current is heated in the motor winding and the electronic...
