Abstract
A damping control system for a vehicle having a suspension located between a plurality of ground engaging members and a vehicle frame includes at least one adjustable shock absorber having an adjustable damping profile.
Claims12
A recreational vehicle, comprising
- a plurality of ground engaging members;
- a frame supported by the plurality of ground engaging members;
- at least one suspension coupling the plurality of ground engaging members to the frame, the at least one suspension including at least one adjustable shock absorber configurable in a plurality of ride modes each having an associated damping profile, the plurality of the ride modes including a first ride mode and a second ride mode;
- a plurality of vehicle condition sensors supported by the plurality of ground engaging members;
- and
- at least one controller operatively coupled to the at least one adjustable shock absorber and the plurality of vehicle condition sensors, the at least one controller receives a plurality of inputs from the plurality of vehicle condition sensors, wherein in each of the first ride mode and the second ride mode the at least one controller adjusts a damping characteristic of the least one adjustable shock absorber based on a plurality of inputs from the plurality of vehicle condition sensors, further wherein the at least one controller determines if the at least one adjustable shock absorber may be reconfigured from the first ride mode of the plurality of ride modes to the second ride mode of the plurality of ride modes by determining if a first condition is satisfied, if the first condition is satisfied then configuring the at least one adjustable shock absorber in the second ride mode, if the first condition is not satisfied then determining if a second condition is satisfied, if the second condition is satisfied then configuring the at least one adjustable shock absorber in the second ride mode, if both the first condition and the second condition are not satisfied remaining in the first ride mode, wherein only one of the first condition and the second condition is based on at least one of the plurality of inputs from the plurality of vehicle condition sensors.

A recreational vehicle, comprising
- a plurality of ground engaging members;
- a frame supported by the plurality of ground engaging members;
- an operator interface including at least one input to select one of a plurality of ride modes, the plurality of ride modes including a first ride mode and a second ride mode;
- at least one suspension coupling the plurality of ground engaging members to the frame, the at least one suspension including at least one adjustable shock absorber having an associated damping profile for each of the first ride mode and the second ride mode;
- a plurality of vehicle condition sensors supported by the plurality of ground engaging members;
- and
- at least one controller operatively coupled to the at least one adjustable shock absorber and the plurality of vehicle condition sensors, the at least one controller receiving a plurality of inputs from the plurality of vehicle condition sensors, wherein in response to a request received through the at least one input of the operator interface to change from the first ride mode to the second ride mode the at least one controller determining if the at least one adjustable shock may be reconfigured from the first ride mode of the plurality of ride modes to the second ride mode of the plurality of ride modes by determining if a first condition is satisfied, if the first condition is satisfied then configuring the at least one shock absorber in the second ride mode, if the first condition is not satisfied then determining if a second condition is satisfied, if the second condition is satisfied then configuring the at least one shock absorber in the second ride mode, if both the first condition and the second condition are not satisfied remaining in the first ride mode, wherein only one of the first condition and the second condition is based on at least one of a plurality of inputs from the plurality of vehicle condition sensors.
