AR Parking Start Region Projection for One-Move Parking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assistance systems do not effectively guide drivers to a beneficial starting position for parking, making the process complex and potentially risky.
Innovation Solution
An electronic computing apparatus determines a starting region on the road for parking, which is projected into the driver's field of view using augmented reality or laser beams, providing a demarcated area for easy alignment and collision avoidance, and optionally assisted parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a parking assistance device displays guiding images on a display unit, then parking guidance information is provided, but the driver cannot easily estimate the distance to the starting region
Solution Approach 1:
The patent introduces an intermediary element - the augmented reality projection of the starting region directly onto the road surface - that bridges the gap between the driver and the actual parking location. This projection serves as a visual mediator that provides both location information and distance estimation simultaneously, eliminating the need for the driver to mentally calculate distances from a separate display.
Solution Approach 2:
The patent replaces the traditional mechanical/display-based information presentation system with an optical projection system using augmented reality. Instead of displaying abstract graphical information on a screen that requires interpretation, the system projects visual cues directly onto the road surface, allowing the driver to perceive distance and location intuitively through natural vision.
2Loss of information
If the starting region is displayed on a display apparatus representation, then parking guidance is provided, but the driver's attention is diverted from the road
Solution Approach 1:
The patent transitions the display of starting region information from a two-dimensional display screen to a three-dimensional spatial projection directly on the road surface. By moving the information display into the driver's actual field of view on the road rather than on a separate screen, the system eliminates the need for the driver to shift attention between the road and the display, thereby maintaining both information delivery and safety.
3Loss of information
If traditional parking assistance systems are used, then parking guidance is provided, but the parking process becomes complex and potentially risky
Solution Approach 1:
The patent employs color-coded visual indicators in the augmented reality projection to convey different types of information about the starting region and parking status. By using color changes to encode information (e.g., different colors for different parking spaces, statuses, or guidance levels), the system simplifies the visual interface and reduces the cognitive complexity for the driver while maintaining comprehensive information delivery.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables simple and precise parking by allowing drivers to easily align their vehicle with the starting region, reducing the risk of accidents and simplifying the parking maneuver.
Implementation Method 1
the starting region is projected by means of augmented reality into a windscreen of the motor vehicle or else is output by means of laser beams onto the road within the field of view of the driver
Data Source
AI summary
The disclosure relates to a method for outputting a starting region for a parking process of a motor vehicle, in which the starting region for the motor vehicle on a road is determined for at least one determined parking space, starting from which region it is possible for the motor vehicle to be parked in the parking space in one go, and the starting region is output overlying the road in a field of view of the driver.
