Abstract
Comfort is an increasingly important issue when buying a car. Modern Diesel engines generate a high engine torque already at low engine speed, which may cause oscillations in the drive line of the vehicle. These oscillations are experienced as unpleasant jerking by the driver. The objective of this article is to present a control concept that prevents the driveline from oscillating, a so-called Anti-Jerk Control.A theoretical model of the drivetrain of a car will be presented, the parameters of which are identified by measured data. As a measure for the oscillations in the driveline the difference between engine speed and wheel speed is used. A controller is designed with help of the root locus technique. The controller concept is evaluated on a test car with a diesel engine. Test results will be presented.
