Abstract

Driveline oscillations, known as 'driveline jerking , 'driveline judder or 'Bonanza effect , may occur by load changes in modern series-production cars. They cause horizontal accelerations in the chassis and the passenger compartment, which may lessen comfort and driveability to an unacceptable extent. These oscillations are usually reduced by so-called 'anti-jerk functions , which combine feedback and feedforward control. In practice, the anti-jerk controller parameters are experimentally optimized to combine comfort with sportiness. Such a procedure requires time-consuming driving tests. Alternatively, this paper proposes a model-based approach. The optimal values for feedback control are investigated by simulation in order to reduce time-expensive driving experiments. The simulation is based on a model of driveline dynamics. The model parameters are estimated from measurement data by means of an Extended Kalman-Filter or a non-linear least-squares optimization procedure. Besides the modelling and identification approach, the results of the model-based controller design are presented. The concept has been validated experimentally on different diesel cars.
