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.
Claims13
(canceled)
A recreational vehicle, comprising:
- a plurality of ground engaging members;
- a frame supported by the plurality of ground engaging members;
- a plurality of suspensions, wherein each of the plurality of suspensions couples a ground engaging member, from the plurality of ground engaging members, to the frame, wherein the plurality of suspensions includes a plurality of adjustable shock absorbers;
- at least one sensor positioned on the recreational vehicle and configured to provide sensor information to a controller;
- and
- the controller operatively coupled to the at least one sensor and the plurality of adjustable shock absorbers, wherein the controller is configured to:
- receive, from the at least one sensor, the sensor information;
- determine, based on the sensor information, a braking event corresponding to the recreational vehicle;
- and
- provide, to at least one of the plurality of adjustable shock absorbers and based on the braking event, one or more commands to result in a decrease of a damping characteristic of the at least one of the plurality of adjustable shock absorbers.

A recreational vehicle comprising:
- a plurality of ground engaging members;
- a frame supported by the plurality of ground engaging members;
- a plurality of suspensions, wherein each of the plurality of suspensions couples a ground engaging member, from the plurality of ground engaging members, to the frame, wherein the plurality of suspensions includes a plurality of adjustable shock absorbers;
- a first sensor positioned on the recreational vehicle and configured to provide braking information to a controller;
- and
- a second sensor positioned on the recreational vehicle and configured to provide acceleration information to the controller;
- the controller operatively coupled to the first sensor, the second sensor, and the plurality of adjustable shock absorbers, wherein the controller is configured to:
- receive, from the first sensor, the braking information;
- receive, from the second sensor, the acceleration information;
- determine a braking event corresponding to the recreational vehicle based on the braking information;
- determine, based on the acceleration information, an amount to reduce a damping characteristic of an adjustable shock absorber from the plurality of adjustable shock absorbers;
- and
- provide, to the adjustable shock absorber and based on the braking event, one or more first commands to result in an adjustment of the damping characteristic of the adjustable shock absorber to the determined amount.
