Abstract
A technique includes receiving, at a controller of a vehicle, the controller including one or more processors, a first request to calibrate a park lock system of the vehicle. The calibration can include commanding, by the controller, a first actuator to move a second actuator to maximum engagement/disengagement positions indicating maximum engagement/disengagement of a park pawl with/from a park gear of a transmission. The calibration can include determining, at the controller, full engagement/disengagement positions for the second actuator based on the maximum engagement/disengagement positions. The controller can then control the engagement/disengagement of the park lock system using the full engagement/disengagement positions for the second actuator, respectively.
