General Motors Front And Rear Park Assist Technology
Front and Rear Park Assist is a General Motors active safety technology that helps the driver park their vehicle and avoid crashing into nearby objects during low-speed vehicle maneuvering when driving forward or backing.
How It Works
Front and Rear Park Assist is activated when the vehicles is traveling at speeds below 5 mph (8 km/h).
The system provides “distance-to-object” and object location alerts to help the driver park and avoid crashing into nearby objects during low-speed maneuvering by using 4 ultrasonic sensors mounted on the front bumper and 4 ultrasonic sensors mounted on the rear bumper. The sensors have the following ranges:
- Front: up to 4 feet (1.3 meters)
- Rear: up to 8 feet (2.4 meters)
The sensors are capable of detecting objects within a zone of 10 inches (25 cm) off ground and below bumper level.
The vehicle’s instrument cluster shows locations for front- or rear-detected objects close to the vehicle. As the vehicle gets closer to the object:
- More bars illuminate, with bar color changing from yellow to amber to red, and
- The interval between rear object detection beeps becomes shorter
When a vehicle is equipped with Front and Rear Park Assist as well as with the Rear Vision Camera, a warning triangle on the camera screen shows where the nearest object has been detected. As the object gets closer, this triangle changes from amber to red and increases in size.
The system also delivers repeated “both side” seat pulses or front or rear beeps when the vehicle is in what is considered to be the “close zone”:
- Forward gear “close zone” is within 1 foot (0.3 meters)
- Reverse gear “close zone” is within 2 feet (0.6 meters)
When an object is first detected while backing, the system delivers 2 “both side” seat pulses or a single rear beep. Rear detection beeps are low-pitched and front detection beeps are high-pitched.
Turning The System On & Off
Front and Rear Park Assist can be toggled on or off using:
- A hard switch (button) with an LED indicator, with a lit LED indicator indicating an ON setting, or
- An option in the vehicle setting menu
