Abstract
A vehicle is equipped, inter alia, with a main drive engine, an electric motor, an air compressor and with an electric current source. To permit an energy-optimized, functional operation of the air compressor, the air compressor is driven by the main drive engine provided the main drive engine is running at sufficient speed, or otherwise, as required, by an electric motor, for example, via a power take-off transmission. In this context, the air compressor provides the process air required for the operation of a fuel cell that also supplies the electric motor.
