Air suspension control

An air suspension system for a vehicle, comprising:

• one or more air springs;
• a controller configured to:
• determine a change in a roughness of a ground surface associated with the vehicle;
• modify a height adjustment tolerance for the suspension system in response to the determined change in roughness, wherein a height adjustment is enacted by changing an amount of air contained by the one or more air springs;
• facilitate modification of the suspension system based on the determined height adjustment tolerance;
• determine a twist of the suspension system based upon a difference between a first lateral displacement difference of a front axle of the vehicle and a second lateral displacement difference of a rear axle of the vehicle;
• and
• determine a subsequent height adjustment parameter for the suspension system based on at least the determined twist.

A method, comprising:

• determining, using a controller, a change in a roughness of a ground surface associated with a vehicle, the roughness determined based on ride height;
• modifying, using the controller, a height adjustment tolerance for a suspension system of the vehicle based on the determined change in roughness;
• facilitating a modification of the suspension system based on the determined height adjustment tolerance;
• determining a twist of the suspension system based upon a difference between a first lateral displacement difference of a front axle of the vehicle and a second lateral displacement difference of a rear axle of the vehicle;
• and
• determining a subsequent height adjustment parameter based at least on the determined twist.
