Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems for autonomous vehicles and mobile devices face challenges in accurately identifying and navigating to pickup and drop-off locations, especially in environments where GPS is unreliable, and lack effective user interaction and augmented reality features for enhanced control.
Innovation Solution
The implementation of an augmented reality system that uses HD maps, object recognition, and AI models to provide precise navigation through overlays on mobile devices and vehicle displays, enabling accurate identification of locations and hand-off points between autonomous and human-driven modes, utilizing sensors like LIDAR and cameras for environment understanding and 3D mapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS is used for navigation, then the system is simple and easy to operate, but the location accuracy deteriorates in environments where GPS is unreliable
Solution Approach 1:
The patent combines multiple navigation systems (GPS, HD maps, LIDAR, cameras, inertial sensors) into an integrated navigation system that fuses data from all sources to achieve accurate location identification even when GPS is unreliable, thereby resolving the contradiction between location accuracy and system complexity
Solution Approach 2:
The navigation system is designed to perform multiple functions: GPS-based navigation, HD map matching, LIDAR-based 3D mapping, object recognition, and inertial navigation. This multi-functional approach allows the system to maintain location accuracy across different environments without requiring separate dedicated systems
2Ease of operation
If traditional navigation systems are used, then the device complexity is low, but the user interaction and identification effectiveness deteriorate
Solution Approach 1:
The patent introduces an augmented reality interface as an intermediary between the navigation system and the user. This AR interface overlays virtual information (pickup/drop-off zones, hand-off points, navigation cues) onto the real-world view, making complex navigation information easily interpretable and improving user interaction effectiveness
Solution Approach 2:
The AR interface uses color coding to convey different types of information: green overlays indicate safe pickup/drop-off zones, red overlays indicate hand-off points, and other colors represent different navigation states. This visual encoding simplifies user interpretation of complex navigation data
3Ease of operation
If AR overlays are added to enhance navigation, then the user interaction improves, but the device complexity increases
Solution Approach 1:
The AR overlay system is segmented into distinct functional modules: pickup/drop-off zone identification, hand-off point marking, navigation path display, and real-time object tracking. Each module processes specific types of information independently, which manages complexity while maintaining comprehensive navigation enhancement

AI summary
An augmented navigational system is provided for autonomous vehicles. The augmented navigational system may further be coupled to an artificial intelligence system that provides object recognition and image recognition. A machine learning system may provide further feedback as to whether the pickup and drop off location was appropriate, and whether the recognition of one or more objects was appropriate.
