摘要： In a method for determining a power limiting value for an electric machine in a vehicle, the electric machine being assigned an energy storage device, an intermediate power value is calculated from a maximally allowable current of the energy storage device and an instantaneous voltage. A corrected intermediate power value is determined by adding at least one power loss to the intermediate power value. A first correction value is determined for reducing the absolute value of the corrected intermediate power value if an instantaneous power of the energy storage device is greater than the absolute value of the calculated intermediate power value. The power limiting value is determined by superimposing the first correction value on the corrected intermediate power value.
