Drivetrain controller for a motor vehicle with at least two power units and a gear-box
First Claim
1. Drivetrain controller for a motor vehicle with at least two drive units (1, 3) and a gearbox (7), comprising decentralized control units (2, 5, 8) for generating the setting signals for the drive units (1, 3) and the gearbox (7), a pedal interpretation unit (20) for determining a torque set value from a parameter characterizing the driver'"'"'s command characterized by a status manager (22) for specifying a set operating state for the drivetrain as a function of the torque set value and the charge state of an energy store (4) and a torque manager (23) for generating control signals for the decentralized control units (2, 5, 8) as a function of the torque set value and the specified set operating state for the drivetrain.

Abstract
A torque set value is determined in a pedal interpretation unit (20) from a parameter which characterises 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.
