The influence of footpegs forces in lane change maneuver

Der Einfluss vom Druck auf die Fussrast beim Fahrspurwechsel

This paper illustrates a novel approach for the study of the lane change maneuver. The purpose is to study the contribution given by the rider through the movement of the body as forces applied on footpegs. A specific instrumentation on motorcycle is required to collect the necessary data during the test session. Over the classical sensors usually applied on Powered Two-Wheelers (PTW), customized load cells have been developed to substitute the original footpegs. The tests have been done by professional riders in a track appositely built with the aim to compare the obtained results with the ones given from similar motorcycles. In this way it has been possible to calculate the Koch index and the Lane Change roll index as described in literature. These indexes consider the action of the rider (as the torque transmitted by the handlebar) and the reaction of the motorcycle (as the roll rate of the motorcycle) normalized by the speed. The main novelty introduced in this work is to study the behavior of the motorcycle (as roll rate) due to the torque applied on handlebar and to the forces applied on footpegs. Tests results show that these forces should be considered for a better identification of the rider’s actions involved in lane change maneuvers. According to the development work done, similar considerations could be extended to the effects produced by the rider through the seat. In this way all the forces and torques applied by the rider on motorcycles will be correctly considered. (A)
