Perpendicular Parking Operation

WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

The perpendicular parking feature is available when the active park assist system has been activated (the active park assist switch is pressed twice) and the IPMA has determined the driver is attempting to maneuver the vehicle into a perpendicular parking space. Using the front active park assist sensors, the multifunction turn signal input from the SCCM, the IPMA begins searching for a parking space. If the turn signal is not active, the IPMA defaults to searching on the passenger side of the vehicle.

The system measures the available parking spaces and its surroundings as the operator drives by to determine if the vehicle can be maneuvered into the available parking space. The IPMA uses inputs from the front active park assist sensors and the wheel speed and rotation data message to find an acceptable parking space. After a space has been located, a chime is sounded through the audio system and the centerstack infotainment display shows a message informing the driver that a parking space has been located on the left or right side and requesting the driver to pull forward to park. After the driver moves the vehicle forward to the appropriate start position as determined by the IPMA, the system requests the driver to stop, shift the transmission into neutral and remove hands from the steering wheel. The IPMA sends the active park assist steering angle request to the PSCM to turn the wheels to an angle which steers the vehicle into the perpendicular parking space on the desired side. A vehicle gear and speed request is sent from the IPMA to the PCM. When needed the PCM will send a brake request to the ABS module to slow or stop the vehicle.

The IPMA determines the perpendicular parking maneuvers are completed based on the final vehicle alignment. The perpendicular parking aid system attempts to center the vehicle between the two vehicles and align the end vehicle angle with the angle of the parked vehicles. If only one vehicle is detected, the system aligns with that vehicle at a distance of 70 to 90 cm (28 to 35 in) in North America and South America or 55 to 75 cm (22 to 30 in) in Europe and Asia Pacific. When the active park assist maneuver is complete, the centerstack infotainment display displays an active park assist finished message followed by an audible chime.
