Torque Pedal for a Car with a Continuously Variable Transmission

For a new concept of a hybrid drive line developed at the Swiss Federal Institute of Technology (ETH), a torque pedal interpretation for the accelerator pedal is investigated. For this purpose, based on a simple nonlinear model of the drive line, a robust nonlinear controller is developed. The controller consists of a nonlinear feedforward controller supported by a nonlinear estimator and a simple linear feedback controller. The robust performance of the control system developed is confirmed by simulations.
