More Information
Summary:An apparatus and a method for controlling operation of a vehicle includes a controller having a processor and a tangible, non-transitory memory. The vehicle includes a park assembly with a park actuator motor having an actuator shaft. The vehicle has a park mode and an out-of-park mode. The controller is configured to determine if the park actuator motor has reached an out-of-park position when a shift command to the out-of-park mode is received. The controller is configured to obtain and store at least one dynamic parameter associated with the park actuator motor prior to the detent member reaching the out-of-park position. The method includes determining a load factor based on the dynamic parameter over time when at least one of a predefined time threshold and a predefined motor position threshold is reached. Operation of the vehicle is controlled based at least partially on the load factor.
