Model based traction control with friction adaption for preventing drivetrain vibration during powerhop acceleration process of front-wheel-drive vehicles

This article presents a control strategy for drivetrain oscillations induced by driving force variation during heavy acceleration processes. The main advance of this approach is the early detection of an impending oscillation from the beginning of the acceleration process. The main challenge is the absence of evaluable vehicle sensor signals at standstill. Therefore the algorithm relies on a physical model. In conjunction with an interpretation of the driver’s input, the algorithm is able to predict the vehicle state in a certain timeframe. In the first part, the physical model which is used to describe the phenomenon sufficiently is introduced. In the following, a comparison between measurements and simulation is given to illustrate the model quality. Finally, the effectiveness of the new approach is demonstrated on the basis of real driving manoeuvres.     «
