The disclosure relates to a method for freeing at least one locked wheel of a vehicle. One step of the method relates to identifying a locking scenario comprising the identification of the at least one locked wheel. A further method step is selecting a wheel freeing strategy being suitable for the identified locking scenario. Another step is directed to applying the selected wheel freeing strategy. Furthermore, the disclosure is directed to a propulsion system for a vehicle having at least one wheel. The propulsion system comprises at least one propulsion actuator. Moreover, at least one wheel speed sensor is provided, the wheel speed sensor being configured for detecting the rotational speed of the at least one wheel. Additionally, the propulsion system has at least one brake unit being configured for braking the at least one wheel and a control unit being configured for performing the above method.
