Method for unlocking a rotor shaft, which strikes and is clamped against a form-fitting element of a locking actuator in a load-related manner, of an electric motor without restriction, computer program, computer program product, system and vehicle

A method for unlocking a rotor shaft of an electric motor, which strikes and is clamped against a form-fitting element of a locking actuator in a load-related manner, without restriction, to drive a vehicle, comprising:

• positioning the rotor shaft from a striking position to a rotational angle position in which it was previously locked without restriction by the form-fitting element to release the rotor shaft;
• recording an absolute position of the rotor shaft by a rotor (shaft) position sensor;
• and
• moving the form-fitting element out of the rotor shaft in a stroke movement.

A computer program product, comprising program code stored on a nontransient computer-readable data carrier in order to perform a method when the program code is executed on a computer for unlocking a rotor shaft of an electric motor, which strikes and is clamped against a form-fitting element of a locking actuator in a load-related manner, without restriction, to drive a vehicle, comprising:

• positioning the rotor shaft from a striking position to a rotational angle position in which it was previously locked without restriction by the form-fitting element in order to release the rotor shaft;
• recording an absolute position of the rotor shaft by a rotor (shaft) position sensor;
• and
• moving the form-fitting element out of the rotor shaft in a stroke movement.
