Analysis of Counter-steering Phenomenon on Motorcycle Dynamics by Scale Modeling

We propose an application of robotics technology to the motion analysis of motorcycles in order to decrease the risk of serious traffic accidents. This paper presents the experimental results with the electric motorcycle model equipped with the DCT mechanism (DCT ; Damping unit, Counter-steering angle, Temporary input), and also shows the results of simulation based on the Sharp* refined model that include the rolling resistance of the front tyre, round profile of tyres and the centrifugal force. In addition, we propose a measuring system for rolling angle of motorcycles with wireless camera. The experimental result of counter-steering phenomenon coincides with the result of simulation qualitatively, and confirms that the DCT mechanism is very useful equipment for data sampling of motorcycles.
