Abstract

A torque set value is determined in a pedal interpretation unit (20) from a parameter which characterizes the drivers command. Operating parameters for the vehicle are evaluated and classified in a driver and situation recognition unit (21). A set operating status for the drivetrain is fixed in a status manager (22), depending upon the torque set value and the output signals from the driver and situation recognition unit. Control signals for remote control units (2, 5, 8) for the drive units and for the gearbox (7) are then generated in a torque manager (23), dependent upon the torque set value and the set operating status.
