General Motors Automatic Park Assist Technology
Automatic Park Assist is a General Motors active safety technology that helps the driver parallel and perpendicular park their vehicle nearly automatically. The system finds a space and automatically steers the vehicle into the parking space while the driver follows text commands, selects gears, and performs all of the braking and acceleration.
How It Works
Automatic Park Assist uses Front Park Assist and Rear Park Assist ultrasonic sensors on the vehicle, as well as one left and one right ultrasonic sensor mounted on the side of the vehicle toward the front. The system finds a parking space when the vehicle is traveling at or below 18 mph (30 km/h) in a Forward gear and steers the vehicle into a parking space in Forward and Reverse gears when traveling at or below 6 mph (10 km/h).
The system works in the following sequence:
- Driver presses Automatic Park Assist button, activating the system to search for a parallel parking space
- Press and hold the same button to switch between parallel and perpendicular parking modes
- System automatically looks for parking spots on the right
- To find a parking spot on the left, the driver must activate the left turn signal
- System provides step-by-step using beeps and instructions in the instrument cluster, such as “stop”, “drive in reverse”, and “parking complete”
- The vehicle does all the necessary steering
- The driver shifts into Forward and Reverse gears and applies throttle
- During the parking process, the system continues to display object detection warnings (such as distance to object messages) and pulses from the Safety Alert Seat (or low-pitched beeps)
- When parking is completed, Automatic Steering and Automatic Parking Assist are turned off
