Abstract
According to the control method, the power/torque that can be supplied by an electric drive motor in a vehicle is handled by setting and adjusting a maximum available level for the power/torque that can actually be supplied; the adjustment includes a reduction of the maximum available level from a peak value to a nominal value after the electric drive motor has supplied an actual power/torque equal to said peak value for a predetermined amount of time.
Claims14
A control method for handling power/torque of an electric drive motor (13) in a vehicle (1), the method comprising the step of setting and adjusting a maximum available threshold (L) for an actual power/torque that can be supplied by said electric drive motor (13) in response to a power/torque request made by a driver of said vehicle;
- the adjustment comprising a reduction of said maximum available threshold (L) from a peak value (L1) to a nominal value (L2);
- characterized in that said maximum available threshold (L) is reduced from said peak value (L1) to said nominal value (L2) after said electric drive motor (13) has supplied an actual power/torque equal to said peak value (L1) for a given amount of time (I).
