Overview - Active Park Assist

NOTE: Vehicles equipped with active park assist use a different parking aid sensor. The IPMA supplies a 12v reference voltage and a ground. The signal circuit is a LIN used to communicate the sensor data with the IPMA.

The active park assist system is a supplementary parking system that assists the operator with the task of parking in three ways:

Parallel Park Assist is activated by pushing the active park assist switch - Detects the available parking space and automatically maneuvers the vehicle into the space by controlling the steering, accelerator, brakes and gear selection.
Perpendicular Park Assist is activated by pushing the active park assist switch - Detects an available parking space and automatically maneuvers the vehicle into the space by controlling the steering, accelerator, brakes and gear selection.
Parallel Park Out Assist is activated by pushing the active park assist switch - Analyzes the parking space currently occupied by the vehicle and automatically maneuvers the vehicle out of the space by controlling the steering, accelerator, brakes and gear selection.

The system visually and/or audibly instructs the operator to park the vehicle through messages in the centerstack infotainment display and audio system warning chimes.

The IPMA uses input from the active park assist sensors, parking aid sensors and a geometrical equation to determine whether the vehicle fits in the parking space and to determine the correct steering angles to request from the PSCM during the parking maneuvers. The system visually and/or audibly instructs the operator to park the vehicle through messages in the centerstack infotainment display and audio system warning chimes. The Active Park Assist system then maneuvers the vehicle into the desired parking space or maneuvers out of the parking space.
