Abstract
A method for controlling a temperature of an electric motor in a vehicle drive train via a fluid supply device having a closed fluid circuit with a fluid pump for conveying a fluid flow, which is to be supplied to the electric motor and which in the process alters its operating temperature. The method comprising comparing one actual value of a safety characteristic value of the electric motor to a predetermined limit value of the safety characteristic value. The method further comprising controlling the fluid flow by switching the fluid supply device between a first operating state and a second operating state at least according to the comparison. In the first operating state, the fluid flow is adjusted according to a predetermined operating characteristic value of the electric motor. In the second operating state, the fluid flow is adjusted so as to be higher than in the first operating state.
