Abstract:
1. A drivetrain controller for a motor vehicle, the motor vehicle including an energy store and a drivetrain having two drive units and a gearbox, said drivetrain controller comprising: decentralized control units for generating setting signals for the two drive units and the gearbox of the drivetrain; a pedal interpretation unit for receiving a driver command parameter characterizing a driver's command and determining a torque set value in response to the driver command parameter; a status manager having a plurality of stored set operating states for the drivetrain, each of said plurality of stored set operating states being associated with control signals characterizing said each of said plurality of stored set operating states, said status manager receiving a signal indicating a charge state of the energy store and being connected to said pedal interpretation unit for selecting a selected set operating state from said plurality of set operating states for the drivetrain in response to the torque set value and the charge state of the energy store; and a torque manager connected to said status manager and said pedal interpretation unit for controlling each of the decentralized control units in response to the torque set value and the control signals associated with the selected set operating state for the drivetrain.
