Advanced motorcycle-infrastructure-driver roll angle profile for loss control prevention

In this paper, we present a new method for the calculation of the maximum roll angle of a motorcycle authorized during driving in curve situation. The proposed approach takes into account the three elements of the driving situation which are the vehicle the driver and the infrastructure. The vehicle dynamics are represented by a dynamic four degrees of freedom model which include longitudinal and lateral dynamics of the motorcycle. The driver behaviour considers his ability in deceleration taking into account his mobilized friction while the infrastructure characteristics introduce a precise definition of the road geometry and the maximal available friction.
