Abstract

In a method for operating a load-dependent power-generating system which supplies electric energy to at least one electric drive motor in a vehicle, a performance setpoint value is determined for the electric drive motor from an accelerator pedal position, and a power request is made to the power-generating system before a torque request to the drive motor. Dynamic movement parameters of the accelerator pedal are also used to calculate the performance setpoint value.
