Abstract
In braking situations, excessive braking torque inputs can cause large pitching motions of a motorcycle, and it may result rear wheel lifting problems. In this paper, riding experiments are conducted on rapid deceleration conditions, and the motion of the motorcycle is analyzed based on the experimental results. The rear suspension mechanism of the test vehicle is modeled and included in a thirteen-degrees-of-freedom rider-motorcycle model, and parameter identification of the rider-motorcycle model is performed. By carrying out simulations, and using the measured brake oil pressure data to braking torque inputs, it is demonstrated that the simulation results are consistent with the experimental results, even if the rear wheel lifting is caused by excessive braking torque inputs.
