Abstract:
A saddle riding type vehicle that reduces steering pull of a handle caused by a disturbance and also prevents degradation in a steering feeling includes a detector that detects a steering angle of a steering shaft, a steering damper, and a control device. The steering damper is arranged around the steering shaft and includes an electromagnet, a magnetic member, and a magnetic fluid stored in a gap between the electromagnet and the magnetic member. The control device includes a steering angular velocity determiner adapted to determine a steering angular velocity based on a steering angle detected by the detector, an instructor adapted to instruct a supply of current to the electromagnet for a first reference time when the determined steering angular velocity exceeds a first reference velocity and to instruct a stopping or reduction of the current supply after the first reference time elapses, and a driver that supplies the electromagnet with current in response to an instruction from the instructor.
