1. 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, automatically and without driver interaction, cycle 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.
