Claim 0:
1. A damping control method for a vehicle having a suspension located between a plurality of ground engaging members and a vehicle frame, a controller, a plurality of vehicle condition sensors, and a user interface, the suspension including a plurality of adjustable shock absorbers including a front right shock absorber, a front left shock absorber, and at least one rear shock absorber and the suspension further including a stabilizer bar linkage coupled between a first portion of the suspension and the vehicle frame, the damping control method comprising:
receiving with the controller a user input from the user interface to provide a user selected mode of damping operation for the plurality of adjustable shock absorbers during operation of the vehicle;
receiving with the controller a plurality of inputs from the plurality of vehicle condition sensors including a z-axis acceleration sensor;
determining with the controller when the vehicle is in an airborne event, the airborne event being determined when the input from the z-axis acceleration sensor indicates z-acceleration of less than a first threshold that is sustained for a time greater than a second threshold to identify the airborne event;
operating the damping control according to an airborne condition when the airborne event is determined, wherein in the airborne condition the controller defines damping characteristics of the plurality of adjustable shock absorbers based on condition modifiers including the user selected mode and z-axis acceleration;
operating the damping control according to the airborne condition, wherein in the airborne condition the controller increases compression damping as a function of detected duration of the airborne event; and
operating the stabilizer bar linkage based on at least one of (i) the user selected mode and (ii) at least one of the plurality of inputs from the plurality of vehicle condition sensors to adjust a stiffness of the stabilizer bar linkage.
