Body leaning control system, and a saddle riding type vehicle having the same
First Claim
Patent Images
1. A body leaning control system for a saddle riding type vehicle capable of making turns by leaning a vehicle body, the body leaning control system comprising:
- a support mechanism arranged to support at least a pair of traveling members that contact a traveling surface and are provided at opposite sides of the vehicle body to be movable up and down relative to the vehicle body;
a resistance applying mechanism arranged to apply to the support mechanism a resistance to up-and-down motions of the pair of traveling members;
a lean amount acquiring device arranged to detect information on a lean amount of the vehicle body;
a controller arranged to perform control, based on detection results received from the lean amount acquiring device, to set the resistance of the resistance applying mechanism to a first resistance when the lean amount of the vehicle body exceeds a first angle, and to set the resistance of the resistance applying mechanism to a second resistance smaller than the first resistance when the lean amount of the vehicle body is equal to or less than the first angle; and
a vehicle speed detecting device arranged to detect a vehicle speed;
whereinthe controller is arranged to set the first angle to include a region where the first angle increases with the vehicle speed, based on a detection result received from the vehicle speed detecting device.

Abstract
A body leaning control system includes a support mechanism arranged to support a pair of wheels to be movable up and down relative to a vehicle body, a resistance applying mechanism arranged to apply to the support mechanism a resistance to up-and-down motions of the pair of wheels, a lean amount acquiring device arranged to detect a lean amount of the vehicle body, and a controller arranged, based on detection results received from the lean amount acquiring device, to set the resistance of the resistance applying mechanism to a first resistance when the lean amount of the vehicle body exceeds a first angle, and to set the resistance of the resistance applying mechanism to a second resistance smaller than the first resistance when the lean amount of the vehicle body is at the first angle or less. This system can conveniently inhibit the vehicle body from leaning in excess of the first angle.
