Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles face challenges in determining their exact position in real-time due to the limitations of GPS solutions, which do not provide dynamic and accurate data on road features and objects, hindering navigation and high-definition map data collection.
Innovation Solution
A system and method for route planning and trip monitoring that involves selecting a digital map route, adding electronic navigation instructions, and distributing them to an in-vehicle navigation device, which determines the vehicle's location and alerts deviations from the planned route, using sensors like LIDAR and cameras for precise lane-specific data collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS solutions are used for position determination, then the system is simple and widely available, but the position accuracy and real-time performance are insufficient for autonomous driving
Solution Approach 1:
The patent combines multiple positioning technologies (GPS, LIDAR, cameras, inertial sensors) into an integrated navigation system that fuses data from various sources to achieve high-precision real-time position determination, resolving the contradiction between accuracy and complexity by making the complex system work together synergistically
Solution Approach 2:
The patent introduces HD maps as an intermediary reference framework that enables precise position determination by matching sensor data against pre-collected high-definition map features, allowing accurate positioning without relying solely on GPS while managing system complexity through a structured approach
2Reliability
If manual route monitoring is used during data collection trips, then the system is simple to implement, but route deviation errors increase and data collection accuracy decreases
Solution Approach 1:
The patent implements a real-time feedback system where the in-vehicle navigation device continuously monitors vehicle position against the planned route, detects deviations, and provides immediate feedback to operators, ensuring high route following accuracy while managing complexity through automated monitoring
Solution Approach 2:
The navigation device performs self-monitoring of route compliance and automatically generates alerts when deviations occur, reducing the need for manual monitoring while maintaining high reliability through automated detection and notification systems
3Stability of the object's composition
If vehicles strictly follow pre-planned routes, then data collection consistency is improved, but the ability to adapt to real-time conditions is reduced
Solution Approach 1:
The patent creates a dynamic route management system where the planned route serves as a stable baseline for consistent data collection, but the system allows real-time adjustments when deviations are detected or conditions change, balancing consistency with adaptability through controlled flexibility
Solution Approach 2:
The patent performs preliminary route planning to establish consistent data collection paths, then applies real-time adjustments when necessary, allowing the system to maintain planned route stability while adapting to actual driving conditions through pre-established flexibility mechanisms

AI summary
The present disclosure provides a data processing system, method, and device for monitoring a high definition map data collection trip. A current vehicle location is determined. Whether the vehicle is following a planned route linked to a data collection trip, based on the current vehicle location is determined. On a condition that the vehicle is not following the planned route, a reason why the vehicle is not following the planned route is determined. An alert is generated, displayed on an in-vehicle navigation device, and uploaded with the reason to a command center.
