1. A method for reducing a driving power of a vehicle drive, comprising:
- detecting a temperature difference between a temperature of at least one component of the vehicle drive and a predetermined temperature threshold value;
detecting an instantaneous driving state of the vehicle drive;
determining whether the instantaneous driving state allows for a reduction in the driving power; and
reducing the driving power of the vehicle drive for lowering the temperature of the at least one component, in order to increase the temperature difference if the instantaneous driving state allows for the reduction in the driving power,wherein for determining whether the instantaneous driving state allows for the reduction in the driving power, the instantaneous driving state is compared with at least one reference driving state from a plurality of reference driving states,wherein at least one of;
(i) the plurality of reference driving states includes at least two of a constant driving state, a braked driving state, a recuperation state, and an accelerated driving state at an acceleration below a predefined acceleration threshold value; and
(ii) the plurality of reference driving states are stored in one of an electronic memory and a lookup table, and wherein the electronic memory and lookup table include an indication whether a particular driving state of the reference driving states is suitable or unsuitable for performing the power reduction.

Abstract
A method for reducing a driving power of a vehicle drive includes detecting a temperature difference between a temperature of at least one component of the vehicle drive and a temperature threshold value, detecting an instantaneous driving state of the vehicle drive, establishing whether or not the instantaneous driving state allows for a reduction in the driving power of the vehicle drive, and reducing the driving power of the vehicle drive for lowering the temperature of the at least one component in order to increase the temperature difference if the instantaneous driving state allows for the reduced driving power.
