METHOD AND APPARATUS FOR CONTROLLING HEATING OF ELECTRIC DRIVE SYSTEM OF VEHICLE, HEATING SYSTEM, AND VEHICLE

A method for controlling heating of an electric drive system of a vehicle, the electric drive system includes a motor controller and a motor, and the method includes: determining that the vehicle is in a travelling state; obtaining a rotation speed value and a torque control value of a motor and obtaining a carrier instruction value of a motor controller when receiving a heating instruction; obtaining a first current instruction value based on the rotation speed value and the torque control value, and obtaining a second current instruction value based on the torque control value and the first current instruction value; adjusting a control signal of the motor controller based on at least one of the second current instruction value or a second carrier frequency; and controlling the motor to operate based on the adjusted control signal, so that the electric drive system generates heat.
