Augmented Reality Driver Assistance Display Merging Subsystems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driver assistance systems in vehicles often present inconsistent and incomplete environmental information to drivers due to independent operation of subsystems, leading to overlapping but incomplete views, especially during parking and maneuvering tasks.
Innovation Solution
A driver assistance system that combines first and second assistance subsystems to generate and display augmented reality content, superimposing images from multiple camera-based systems to provide a unified, coherent, and informative view of the vehicle's surroundings, including virtual markers and trajectories, on a single display device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple assistance subsystems operate independently with separate displays, then each subsystem can provide specialized information, but the driver receives inconsistent and incomplete environmental information across different display locations
Solution Approach 1:
The patent merges multiple assistance subsystems (electronic rear-view mirror system and view system) into a single integrated display location. The first image from the electronic mirror subsystem and second image from the view system are combined and displayed together on one display device, eliminating information inconsistency and providing a comprehensive environmental view without requiring multiple separate displays.
Solution Approach 2:
The integrated display device serves multiple functions simultaneously: it displays the electronic rear-view mirror image, the view system image, and combines them into a unified augmented reality presentation. This multi-functional approach replaces multiple specialized displays with a single universal display that provides all necessary environmental information.
2Adaptability or versatility
If electronic mirrors and view systems display overlapping areas, then the driver can see the same area from different perspectives, but distance markers and auxiliary lines are missing from one of the views
Solution Approach 1:
The patent combines the electronic mirror image and view system image in a way that preserves the perspective advantages of both while supplementing each with the other's unique information. The display device shows both images simultaneously or in combination, ensuring that distance markers from the view system are visible alongside the electronic mirror's perspective, eliminating the problem of missing assistance information.
Solution Approach 2:
Different regions of the display are optimized to show different types of information: one area displays the electronic mirror image with its perspective advantages, while another area or overlay displays the view system image with distance markers and auxiliary lines. This local optimization ensures that each type of assistance information is visible in the most appropriate context.
3Ease of operation
If separate display locations are used for different assistance subsystems, then each subsystem can be optimized independently, but the driver must switch between displays to get complete information
Solution Approach 1:
The patent merges all assistance subsystem information into a single display location, allowing the driver to access complete environmental information in one place. The integrated display shows both the electronic mirror image and view system image simultaneously, eliminating the need to switch between displays and reducing the time required to gather complete information about the vehicle's surroundings.

AI summary
A driver assistance system for a motor vehicle having a first assistance subsystem for capturing a first sub-area of an environment of the motor vehicle and having a second assistance subsystem for capturing a second sub-area of the environment. The first assistance subsystem is configured to generate a first image of the first sub-area and the second assistance subsystem is configured to generate a second image of the second sub-area. The driver assistance system has a display device for displaying at least the first image. The display device being configured to display a first augmented reality, the first augmented reality being generated by superimposition of the first image with first assistance information of the first assistance subsystem as the first augmented reality content and by superimposition with second assistance information of the second assistance subsystem as the second augmented reality content.
