Intelligent Parking Assist System (IPAS), also known as the Advanced Parking Guidance System (APGS), is an automatic car parking system technology that assists drivers in parking their vehicle with the help of car parking sensors, rear-view cameras, sonar parking sensors, etc. Many new drivers experience that the driving is easy, but the parking is difficult, therefore the traditional parking assistance system gradually becomes a necessarily safe device for the car parking. However there are still some questions when parking, the reversing radar is also helpless. Therefore video camera parking system is growing more and more popularly.

Operation of Intelligent Parking Assist System (IPAS)

The initial version of the Intelligent Parking Assist System was designed for reverse parallel parking. Driver intervention is not required, as the system estimates the size of the parking space and maneuveres the vehicle appropriately. This can be done by an onboard computer which uses cameras built into the forward and rear of the car. Sensors located at similar locations detects the proximity of nearby vehicles. The dashboard displays an image of the parking lot, and the driver would then have to determine the exact position that the vehicle in the lot via the arrows which appears on the screen. Using the arrows, the user would set the location of the vehicle in the space. When satisfied, the user presses the “Set” button, which then activates the IPAS. The system then takes over steering control to maneuver the vehicle.

The Intelligent Parking Assist System (IPAS) or the Advanced Parking Guidance System (APGS) uses computer processors which are tied to the vehicle’s (sonar warning system) feature, backup camera, and two additional forward sensors on the front side fenders. The sonar park sensors, known as “Intuitive Parking Assist” which includes multiple sensors on the forward and rear bumpers which detect obstacles, allowing the vehicle to sound warnings and calculate optimum steering angles during regular parking. These sensors plus the two additional parking sensors are tied to a central computer processor, which in turn is integrated with the backup camera system to provide the driver parking information.

When the sonar park sensors feature is used, the processors calculate steering angle data which are displayed on the navigation/camera touchscreen along with obstacle information. The Intelligent Parking Assist System expands on this capability and is accessible when the vehicle is shifted to reverse (which automatically activates the backup camera). When in reverse, the backup camera screen features parking buttons which can be used to activate automated parking procedures. When the Intelligent Parking Assist System is activated, the central processor calculates the optimum parallel or reverse park steering angles and then interfaces with the Electric Power Steering systems of the vehicle to guide the car into the parking spot.
