Abstract

The drive train controller is used to calculate the position of the accelerator pedal which is interpreted as the wheel torque or transmission output torque desired by the driver, in order to calculate setpoint values for the torque to be output by the drive train. It contains a control circuit in which the desired wheel torque is evaluated, together with further operating parameters of the motor vehicle, in a fuzzy system. It outputs an output signal by which the wheel torque to be exerted on the roadway by the wheels of a motor vehicle is defined.
