The invention discloses a pure electric vehicle motor active heating control method based on a driving motor controller, which utilizes the original configuration of a pure electric vehicle to enable the motor to run at low efficiency by controlling the switch of an IGBT (Insulated Gate Bipolar Translator), thereby realizing stable heating. Besides, the current total battery power, the current motor current value, the current power supply input power, the current PTC heating power and the current compressor power are obtained by taking a heating power request and a torque request on a bus as targets, and a torque instruction and a heating instruction are closed at the same time by taking torque priority as a principle, so that the current of a motor is controlled; closed-loop output of continuous heating power of the motor in the running process of the vehicle is achieved, and then heat is brought to a power battery and a passenger compartment through a whole vehicle heat management system. The driving motor controller serves as a control main body for active heating, a corresponding strategy algorithm is matched, a stable and reliable heat source can be generated, additional hardware cost does not need to be increased, and energy can be provided for battery preheating and passenger compartment heating in the static state and the driving state.
