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.
Claims12
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 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 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 the sway bar to one of the left side suspension and the right side suspension;
- 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.

A vehicle comprising:
- a plurality of ground engaging members;
- a frame supported by the plurality of ground engaging members;
- an operator area including an operator seat supported by the frame;
- a first suspension moveably coupling a first ground engaging member to the frame;
- a first electronically controlled shock absorber having a first end moveably coupled to first suspension and a second end moveably coupled to the frame;
- a first sensor supported by the vehicle to monitor a first characteristic;
- and
- an electronic controller operatively coupled to the first electronically controlled shock absorber to control a damping characteristic of the first electronically controlled shock absorber, the electronic controller being operatively coupled to the first sensor and controlling the damping characteristic of the first electronically controlled shock absorber based at least on a frequency characteristic based on the monitored first characteristic.
