Abstract

Engines of modern cars are able to generate quick variations of engine torque if the driver changes the position of the acceleration pedal abruptly. Due to these changes, driveline oscillations may occur and lead to unpleasant longitudinal accelerations in the passenger compartment. Because nowadays the aspect of comfort is an increasing issue, a so called anti-jerk controller is implemented in the electronic control unit to avoid these unpleasant oscillations. The objective of this article is to present a new model predictive anti-jerk controller, which has several advantages to todays anti-jerk controller structure. Time-consuming driving tests during application can be reduced and it is easily possible to adjust different vehicle dynamics by the drivers themselves without extra calibration effort for additional parameter settings. A model of driveline dynamics is presented. The model parameters are estimated from measurement data by means of an Extended Kalman-Filter. A model predictive controller is designed and performance of the control structure has been tested on different diesel cars.
