Steering damper control apparatus, and a saddle riding type vehicle having the same

摘要

In a steering damper control apparatus, when a command value output unit detects an idle spin of a rear wheel, a damper driver increases a damping force of an MR damper to be higher than a damping force thereof used when the rear wheel is not spinning idly. Therefore, skidding of the rear wheel is prevented to prevent a posture change of a motorcycle. As a result, a driving direction of the rear wheel deviating from a traveling direction is prevented to efficiently use the drive of the rear wheel during traveling.

主权项

1. A steering damper control apparatus to control a steering damping force, the steering damper control apparatus comprising:
a damper having an adjustable steering damping force; an idle spin detecting device that detects an idle spin of a rear wheel; and a damping force adjusting device that adjusts the damping force of the damper to be higher when the idle spin detecting device detects an idle spin than the damping force of the damper when the rear wheel is not in an idle spin; wherein the idle spin detecting device includes:
a front wheel rotational frequency detecting device that detects a rotational frequency of a front wheel;a rear wheel rotational frequency detecting device that detects a rotational frequency of the rear wheel;a difference calculating device that calculates a difference in rotational frequency between the front wheel and the rear wheel; anda distinguishing device that distinguishes an occurrence of an idle spin based on the difference; the distinguishing device includes a storage device that stores a first threshold value, and distinguishes an occurrence of an idle spin based on the difference having exceeded the first threshold value; the storage device includes, stored therein, a second threshold value larger than the first threshold value; and the damping force adjusting device increases the damping force to a maximum when the difference in rotational frequency between the front wheel and the rear wheel is equal to or larger than the second threshold value.
