Development of Riding Simulator for Analyzing Rider Behavior

Most riding simulators adopt the motorcycle model that uses steering torque as an input. In this paper, we propose a motorcycle model that uses steering angle as an input. This is because normally, examinees require a long time to get used to the common steering torque type riding simulator. We checked the validity of our steering angle model by analyzing the frequency response of the model and comparing it to the linearized BikeSim model. The results show that the value of yaw rate and the roll angle coincides with the linearized BikeSim model results of a motorcycle constantly circling, when the steering torque input period is under 0.1 [s-1]. We also measured the steering angle, the speed, the roll angle and the yaw rate of the motorcycle in the practical riding test. These parameters lead us to our algorithm calculating the roll angle and the yaw rate from steering angle and speed. We applied the algorithm to the riding pattern data that simulates the situation of turning in an intersection. The results showed that the calculated data of roll angle and yaw rate are almost the same as the measured data. From these results, this proposed model can be said that it is appropriate to be used in a riding simulator for analyzing rider behavior.
