Parallel Park Out Assist Operation
Parallel park out assist is available immediately after a parallel park was completed or after an ignition on. The driver must activate the active park assist system by pressing the active park assist switch once, using the turn signal before the system measures the location, select the side to exit the parking spot. Once the turn signal status is received from the SCCM, the IPMA verifies the indicated side is clear by analyzing the clearance around the vehicle using input from the active park assist sensors and the parking aid sensors. When the indicated side is clear of obstructions, the centerstack infotainment display shows a message informing the driver to remove hands from the steering wheel and shift to neutral, depending on the detected clearances to the front and rear of the vehicle. After the transmission is shifted and no driver input torque on the steering wheel is detected (driver has removed their hands from the wheel), the system slowly pulls out of the parking spot. The IPMA sends the active park assist steering angle request to the PSCM to turn the wheels to an angle which steers the vehicle out of the parallel 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 that the parallel park out assist maneuvers are complete when a clear path to exit the parking space is detected. When the maneuver is complete, a chime is played and the centerstack infotainment display shows a message informing the driver to take control of the steering. It remains the responsibility of the driver to check for safe conditions when entering traffic from a parking space.
The parallel park out assist system is only for exiting parallel spots.
