METHOD AND DEVICE FOR THE THERMAL PROTECTION OF AN ELECTRIC BODY OF A MOTOR VEHICLE

摘要

The invention relates to a device for the thermal protection of at least one electric body (2, 3, 4) of a motor vehicle provided with an electric motor (3), said device comprising means (5, 6) for measuring a threshold temperature of said electric body (2) and a rotational speed of the electric motor (3), and a torque limiting means (7) that can produce a torque threshold for the electric motor (3) and comprises a power determining means (9) for determining a maximum mechanical power according to the threshold temperature, said torque threshold being produced according to the rotational speed of the electric motor (3) and the maximum mechanical power determined.
