Training System for Optimal Braking on a Powered Two Wheeler

Improving rider skills while performing a braking maneuver supported by a real-time training device embedded in the motorcycle represents an innovative strategy to deal with safety issues associated to the use of powered two wheelers. A challenging aspect of the braking trainer system is the estimation of the friction coefficients between wheel and road surface on each wheel. This paper presents the possible methods to evaluate the current and maximum friction coefficients during a braking maneuver. The proposed approach was positively validated through multi-body simulations and experimental data acquired in naturalistic riding conditions.
