Friction Potential Estimation

Project Description

The Tire-road contact is the only connection between a vehicle and the ground and has consequently a crucial influence on the vehicle’s driving behaviour. Due to this fact, the friction potential is an important parameter for all dynamic vehicle control systems such as the anti-lock braking system (ABS) or (motorcycle) stability control system.

Effect-based methods for estimating the friction potential are developed within the project, where the maximum adhesion potential estimation is based on the change of the motorcycle and tire behaviour. For implementation in a vehicle, a real-time capable motorcycle/-tyre model is required that represents the dynamic behaviour of the motorcycle and, in particular, the tire forces and torques at various driving conditions sufficiently well.

Project Goals

Promising estimation methods based on longitudinal excitation using simulations are to be developed in this project to demonstrate their potential. The selected models should also be suitable for implementation in a motorcycle.
