Suspension system with improved ability to avoid getting stuck or get unstuck

A vehicle control system comprising:

• a vehicle sensor assembly measuring vehicle motion parameters;
• a wheel speed sensor associated with one or more wheels of the vehicle to determine a wheel speed of each of the one or more wheels;
• a controller operably coupled to the vehicle sensor assembly and the wheel speed sensor to:
• determine a proximity to a stuck condition based on the vehicle motion parameters and the wheel speed;
• generate a notification to a driver of the vehicle in response to the proximity to the stuck condition indicating that the vehicle is either in a stuck condition or a nearly stuck condition;
• and
• responsive to driver selection of an unstuck mode, execute an unstuck algorithm to automatically control operation of the vehicle to achieve a free condition,
• wherein generating the notification comprises informing the driver of an automatic response initiated in response to the proximity to the stuck condition indicating that the vehicle is in a nearly stuck condition,
• wherein the system further comprises a suspension position sensor,
• wherein the automatic response comprises initiating a change to a suspension component based on suspension information provided by the suspension position sensor, and
• wherein the change to the suspension component comprises connecting or disconnecting an anti-roll bar (ARB) or increasing a spring rate of air springs.

A method of controlling a vehicle comprising:

• determining a proximity to a stuck condition based on measured vehicle motion parameters and a wheel speed measured by a wheel speed sensor associated with one or more wheels of the vehicle;
• generating a notification to a driver of the vehicle in response to the proximity to the stuck condition indicating that the vehicle is either in a stuck condition or a nearly stuck condition;
• and
• responsive to driver selection of an unstuck mode, automatically and without driver interaction, cycling through execution of a multi-modal algorithm in which each mode of the multi-modal algorithm employs, when executed, a different strategy for advancing the vehicle to a free condition while an actuator remains actuated.
