Claim 26:
27. A vehicle having:
a frame;
a suspension located between a plurality of ground engaging members and the frame, 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 further including a stabilizer bar linkage coupled between a first portion of the suspension and the frame;
a plurality of vehicle condition sensors,
a user interface,
a controller operable to control operation of the suspension, the controller including instructions thereon that when interpreted by the controller cause the controller to:
receive 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;
receive a plurality of inputs from the plurality of vehicle condition sensors including a z-axis acceleration sensor;
detect positive vertical acceleration via the input from the z-axis acceleration sensor;
determine when the vehicle is in a landing condition, the landing condition being determined when the input from the z-axis acceleration sensor indicates z-acceleration of greater than a first threshold that is sustained for a time greater than a second threshold;
operate the damping control according to the landing condition when a landing condition is determined, wherein in the landing 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;
operate the damping control according to the landing condition, wherein in the landing condition the controller increases rebound damping; and
operate the stabilizer bar linkage based on the user selected mode to adjust a stiffness of the stabilizer bar linkage.
