METHOD AND APPARATUS FOR INHIBITING VEHICLE VIBRATION DURING SELF-HEATING PROCESS OF BATTERY, AND AUTOMOBILE

Abstract: a method for inhibiting vehicle vibration during self-heating of a battery, the method is applicable to a vehicle including a power battery pack, a first motor, and a second motor. the method includes: controlling the power battery pack to output a drive current to the first motor to drive the first motor to rotate, where when the first motor rotates, the first motor drives the second motor to rotate; controlling the power battery pack to output a self-heating current to the second motor to self-heat a power battery; obtaining a real-time rotation speed of the first motor; and controlling a fundamental frequency of the self-heating current according to the real-time rotation speed, to stagger the fundamental frequency and the real-time rotation speed.
