Title:
SADDLE RIDING TYPE VEHICLE AND STEERING DAMPER DEVICE UTILIZED FOR SADDLE RIDING TYPE VEHICLE
Document Type and Number:
Japanese Patent JP2012025181
Kind Code:
A
Abstract:

To provide a saddle riding type vehicle which suppresses deflection of a handle caused by a disturbance and also prevents a degradation in steering feeling.

The saddle riding type vehicle includes: a detection device 26, which detects a steering angle of a steering shaft 24; a steering damper 30, and a control device 40. The steering damper 30 is arranged around the steering shaft 24 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 40 includes: a steering angular velocity determination means, which determines a steering angular velocity based on a steering angle detected by the detection device 26; an instructor, which instructs a supply of a current to the electromagnet for a first reference time when the determined steering angular velocity exceeds a first reference velocity and instructs a stopping or reduction of the current supply after the lapse of the first reference time; and a drive device, which supplies the electromagnet with a current in response to an instruction from the instructor.
