Vehicle AR Display Cues for Forward-Reverse Parking Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality (AR) technologies for vehicle guidance, particularly in parking and charging scenarios, lack intuitiveness and completeness, making it difficult for inexperienced drivers to navigate and accurately park or charge their vehicles, especially in complex spaces.
Innovation Solution
An AR display device that uses ADAS sensing data and control data to provide a more intuitive AR graphic interface, allowing real-time guidance by recognizing the vehicle's location and state, searching for optimal parking or charging areas, and dynamically updating the interface to guide the vehicle through forward and reverse driving states, preventing prohibited directions and offering route guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing AR technology is used for route guidance, then AR images can be displayed, but the guidance is not intuitive and difficult to distinguish from other AR features
Solution Approach 1:
The patent segments the AR guidance system into distinct components: route guidance arrows are separated from parking/charging space markers, and further divided into forward driving indicators and reverse driving indicators. Each segment has unique visual characteristics (color, shape, position) that make them easily distinguishable. For example, route guidance uses arrows overlaid on the road surface, while parking spaces are marked with rectangular boundaries and charging stations with circular markers.
Solution Approach 2:
The patent employs color coding to differentiate various AR guidance features. Route guidance arrows use specific colors to indicate direction, while parking spaces and charging stations use distinct color schemes. The system also uses color changes to indicate different driving states (forward/reverse) and to highlight important information, making the guidance intuitive and easily distinguishable from other AR features.
2Measurement precision
If AR guidance is provided for parking in complicated spaces, then parking locations can be identified, but inexperienced drivers still have difficulty finding desired locations
Solution Approach 1:
The system performs preliminary actions by pre-identifying and marking parking and charging spaces before the driver arrives. The AR display shows available parking spaces and charging stations in advance with clear visual markers, allowing inexperienced drivers to plan their approach. The system also pre-calculates the optimal path to the selected space and prepares guidance instructions beforehand.
Solution Approach 2:
The patent introduces an intermediary AR interface that mediates between the complex parking space environment and the driver. This interface provides simplified visual markers for parking spaces and charging stations, overlaying them on the real-world view through the windshield. The intermediary layer translates complex spatial information into intuitive visual cues that are easy to interpret.
3Manufacturing precision
If the AR graphic interface is updated in real time to guide driving states, then accurate guidance is provided, but the system complexity increases
Solution Approach 1:
The patent implements dynamic AR graphics that automatically adapt to the vehicle's driving state. The system detects whether the vehicle is moving forward or in reverse and dynamically updates the AR display to show appropriate guidance arrows and markers. When the vehicle reverses, the AR interface switches to show reverse driving guidance, and when moving forward, it displays forward guidance. This dynamic adaptation provides accurate guidance without requiring complex manual adjustments.
4Adaptability or versatility
If the AR system provides comprehensive guidance for both route and parking/charging, then complete information is provided, but the interface becomes less intuitive
Solution Approach 1:
The patent segments the comprehensive guidance information into distinct visual categories: route guidance (arrows on road), parking space markers (rectangular boundaries), and charging station markers (circular markers). Each segment serves a specific function and is visually differentiated, allowing the system to provide complete information while maintaining interface intuitiveness through clear visual hierarchy and separation.

AI summary
An Augmented Reality, AR, display device (800) interoperating with a vehicle and a method for operating the same are disclosed. An AR display device (800) according to the present disclosure can provide an intuitive AR route to a parking available area or charging available area in a parking lot or charging station based on ADAS sensing data of a vehicle and/or control data of a parking lot/charging station. It is recognized that the vehicle has arrived in from of a selected parking space or charger, and an AR graphic interface can be changed in real time to sequentially guide forward driving, a change point to reverse driving, and reverse driving to the vehicle in correspondence to a current driving state of the vehicle, such that the vehicle can be parked accurately in the parking space or in front of the charger.
