Riding simulation system

Abstract

This invention provides a riding simulation system comprising a base, a support, a handlebar, at least one pressure sensor, a processor, and a motor. The support is rotatable relative to the base about a first axis for tilting rotation. The handlebar is rotatable relative to the support about a second axis for yaw rotation. The at least one pressure sensor senses a tilting thrust applied by a user to the handlebar. The processor generates a control signal based on the tilting thrust. The motor provides rotational resistance to the yaw rotation of the handlebar and adjusts the rotational resistance according to the control signal, wherein the rotational resistance decreases as the tilting thrust increases.
