Abstract:
1. A method for controlling a vehicle park lock system, comprising: receiving, at a controller of the vehicle, the controller including one or more processors, a first request to calibrate the park lock system of the vehicle; commanding, by the controller, a first actuator to move a second actuator to maximum engagement and maximum disengagement positions in response to receiving the first request, the second actuator being configured to engage/disengage a park pawl of the park lock system with/from a park gear of a transmission of the vehicle, the maximum engagement position indicating a maximum engagement of the park pawl with the park gear, the maximum disengagement position indicating a maximum disengagement of the park pawl from the park gear; determining, at the controller, full engagement and full disengagement positions for the second actuator based on the maximum engagement and maximum disengagement positions, the full engagement position indicating full engagement but less than the maximum engagement of the park pawl with the park gear, the full disengagement position indicating full disengagement but less than maximum disengagement of the park pawl from the park gear; and controlling, by the controller, the first actuator to move the second actuator to engage/disengage the park pawl with/from the park gear using the full engagement and full disengagement positions, respectively.
