1. A method for using autonomous vehicle assistance for freeing a vehicle from a stuck condition, comprising:
receiving sensor data from a vehicle sensor indicating a condition of the vehicle, wherein the sensor data comprises throttle data associated with a throttle control circuit of the vehicle and vehicle movement data associated with a position determination system of the vehicle;
when the throttle data identifies application of a throttle and the vehicle movement data identifies no forward or backward movement of the vehicle, determining from the sensor data that the vehicle is in the stuck condition;
obtaining a learned solution for freeing the vehicle from the stuck condition, the learned solution comprising a vehicle extrication technique output from a machine learning algorithm trained using data from at least one previously employed vehicle extrication technique and comprises a level of successful vehicle extrication of the at least one previously employed vehicle extrication technique; and
taking over at least partial control of the vehicle from its operator and applying the learned solution to the vehicle to extricate the vehicle from the stuck condition, wherein application of the learned solution operates the vehicle to rock the vehicle from the stuck condition using timing of gear shifts or an adjusted application of torque to drive wheels of the vehicle.
