METHOD FOR HEATING A MOTOR VEHICLE

A method for heating a motor vehicle having a three-phase electric motor as a traction motor includes providing a pulse-controlled inverter for supplying power to the electric motor and providing a coolant circuit for cooling the electric motor and the pulse-controlled inverter using coolant, the coolant circuit using the coolant to supply heat to a heat exchanger for heating a passenger compartment and/or a vehicle battery, wherein when the electric motor is stationary, a positive d current and/or negative d current is controlled in a d-axis, with the result that heat loss is generated, the heat loss being introduced into the coolant.
