Driveline oscillation control by using a dry clutch system

The reduction of vehicle driveline vibrations such as shuffle and shunt by controlling a dry clutch system is studied in this paper. For this purpose a dynamic model for the driveline of a typical passenger car including backlash, clutch friction model and tire slip is developed. A linear controller is designed for the clutch control and damping of driveline vibrations. The results of this research show that by using a dry clutch system, vehicle longitudinal vibrations can be controlled effectively. Moreover, this method does not have the disadvantages of other solutions including deteriorating air pollution and vehicle performance. In addition it involves low costs especially in cars with automated manual transmission system (AMT).
