Abstract
A damping control system for a vehicle having a suspension located between a plurality of ground engaging members and a vehicle frame are disclosed. The vehicle including at least one adjustable shock absorber having an adjustable damping characteristic.
Claims20
A vehicle comprising:
- a plurality of ground engaging members including a first portion on a left side of a vertical longitudinal centerline plane of the vehicle and a second portion on a right side of the vertical longitudinal centerline plane of the vehicle;
- a frame supported by the plurality of ground engaging members;
- an operator area including an operator seat supported by the frame;
- a left side suspension comprising a first arm moveably coupling a first ground engaging member of the first portion of the plurality of ground engaging members to the frame;
- a first electronically controlled shock absorber having a first end moveably coupled to the left side suspension and a second end moveably coupled to the frame;
- a right side suspension comprising a second arm moveably coupling a first ground engaging member of the second portion of the plurality of ground engaging members to the frame;
- a second electronically controlled shock absorber having a first end moveably coupled to the right side suspension and a second end moveably coupled to the frame;
- a sway bar moveably coupled to the frame, the sway bar having a first end moveably coupled to the left side suspension and a second end moveably coupled to the right side suspension;
- a third electronically controlled shock absorber positioned to operatively couple to the sway bar on a first end and to one of the first arm of the left side suspension and the second arm of the right side suspension on a second end independent of the respective first electronically controlled shock absorber and the second electronically controlled shock absorber;
- and
- an electronic controller operatively coupled to the first electronically controlled shock absorber, the second electronically controlled shock absorber, and the third electronically controlled shock absorber, the electronic controller setting a first characteristic of the first electronically controlled shock absorber, a second characteristic of the second electronically controlled shock absorber, and a third characteristic of the third electronically controlled shock absorber.
