Process for dynamically adjusting the power for a vehicle having a fuel cell

摘要

The invention provides a process for dynamically adjusting the power of an electric driving unit of a vehicle which is supplied with electric energy by a fuel cell, the power of the fuel cell or the provided fuel cell current being controlled by means of the supplied air volume flow. The air volume flow is adjusted by the rotational speed of a compressor, a desired rotational speed value being predetermined for the compressor based on an accelerator pedal demand. Simultaneously, based on the measured air flow volume, the actually available fuel cell current is determined and therefrom a corrected accelerator pedal demand is determined. During the starting operation, the accelerator pedal demand is supplied directly to the driving unit, whereas, at higher rotational speeds, it is limited by the corrected accelerator pedal demand.
