Parking Aid System (With Active Park Assist): Overview Ford Kuga II

Active Park Assist Operation

Note. Refer to the Owner's Literature for active park assist and graphical centerstack infotainment displays.

Note. Aftermarket or modified audio systems may disable necessary audible warnings.

The PAM communicates with several modules to control the functions of the active park assist system.

When the active park assist switch is pressed, the centerstack infotainment display shows a message that the active park assist is searching for a parking space on the left or right side. The multifunction switch turn signal input determines the side of vehicle in which the driver is searching for a parking space. If the turn signal is not active, the active park assist system defaults to searching on the passenger side of the vehicle.

The system measures the available parking spaces and their surroundings as the operator drives by to determine if the vehicle can be maneuvered into the available parking space. The minimum parking space length that the active park assist system identifies is approximately 1.2 times the length of the vehicle and is determined by inputs from the active park assist sensors and the wheel rotation data.

After a parking space has been located, a chime sounds 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 PAM , the system will request the driver to stop, shift to the transmission into reverse and remove hands from the steering wheel. After the transmission is in reverse and no driver input torque is detected on the steering wheel by the PSCM , the active park assist system takes control of the steering and prompts the driver to begin backing into the parking space. The active park assist system sounds audio tones and issues commands through the centerstack infotainment display instructing the driver to back up and pull forward as necessary while the system controls the steering to position the vehicle within the detected parking space. The operator maintains full control of the gear shifting, accelerator and brakes during active park assist maneuvers.

The PAM determines that the active park maneuvers are completed based on the final vehicle alignment. The vehicle should be located approximately 0 to 304.8 mm (12 in) from the street curb if a curb is detected, otherwise the system aligns the vehicle to the front vehicle. When the active park assist maneuver is complete, the centerstack infotainment display displays an active park assist finished message followed by an audible chime.

Pressing and releasing the active park assist switch at any time during an active park assist maneuver disables the active park assist system. If the system is disabled by the operator after the system starts to control the steering, the centerstack infotainment display displays an active park assist canceled message followed by a warning chime.

The active park assist system utilizes steering angle inputs, vehicle wheel roll count, wheel direction, active park assist sensor inputs, vehicle speed and transmission selection to calculate vehicle position and distance in relation to the parking space. The inputs are used by the PAM to command the steering system to assist with the steering wheel control to maneuver the vehicle into the parking space.

If an input module fault or other system concern is present, the active park assist system is disabled or prevents the system from activating. An active park assist fault message is displayed by the centerstack infotainment display and a DTC is set in the PAM .

Certain conditions can cause the active park assist system to incorrectly align the vehicle in the parking space

1. A spare tire installed or one of the tires on the vehicle has significantly more or less tread wear than the other tires.
2. The vehicle has been equipped with various accessories (cycle rack, trailer) which are not recognized by the active park assist system.
3. The factory-installed tire size is not used on the vehicle.
4. Poor ambient weather conditions such as heavy rain or snow.
5. The active park assist sensors are damaged or obstructed.
6. The curb along the parking space is irregular.
7. The vehicle or objects bordering the space are not positioned correctly.
8. The parking space dimensions or parked object positions have changed after the vehicle has initially passed the parking space.
9. The ambient temperature changes quickly such as the vehicle driven from a heated garage into the cold or just leaving a car wash before the system was activated.
10. One of the surrounding parked vehicles has an elevated or overhanging attachment such as a salt spreader or a large truck bed, that the sensors cannot detect.
