Vehicular Electronic Device Real-Time Route Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation systems take time to process and update high-definition map data, leading to delays in route changes when a vehicle approaches an intersection, especially when the traveling lane differs from the preset route.
Innovation Solution
A vehicular electronic device equipped with a processor that continuously generates electronic horizon data using HD map data, adjusts the route based on the vehicle's location and traffic signal information, changing the main path to match the traveling lane and upcoming traffic signal, thereby updating the route in real-time before the vehicle enters the intersection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If HD map data is received and processed from a cloud server to generate electronic horizon data, then the route information is updated, but it takes significant time to process the data and update the route
Solution Approach 1:
The system performs preliminary actions by continuously receiving and preprocessing HD map data from the cloud server before it is actually needed. The electronic horizon data is continuously generated and updated in the background, so when a route change is needed at an intersection, the processed data is already available for immediate use, eliminating the need for time-consuming processing at the moment of decision
Solution Approach 2:
The system transitions from static route planning to dynamic continuous updating. The electronic horizon data is continuously generated and updated based on real-time vehicle location and traffic conditions, allowing the route information to adapt dynamically to changing situations without requiring full reprocessing
2Measurement precision
If the system waits for HD map data processing to complete before determining the route at an intersection, then accurate route information is obtained, but the response time for route changes is delayed
Solution Approach 1:
The system continuously generates electronic horizon data and determines potential routes in advance while the vehicle is approaching the intersection. By the time the vehicle reaches the intersection, the route determination is already complete or can be quickly finalized using pre-processed data, ensuring both accuracy and speed
Solution Approach 2:
The route determination process is segmented into multiple stages: continuous background processing of HD map data, preliminary route calculation as the vehicle approaches, and final route selection at the intersection. This segmentation allows different parts of the process to occur at different times, improving overall response speed without sacrificing accuracy
3Adaptability or versatility
If the system processes HD map data for a range not containing the existing route to change the route, then new route options are available, but the processing time increases
Solution Approach 1:
The system dynamically adjusts the scope of HD map data processing based on the vehicle's current location and destination. Instead of always processing the entire map range, the system focuses on relevant areas, continuously updating electronic horizon data only where needed, which maintains route flexibility while reducing processing time
Solution Approach 2:
The system applies different processing quality and detail levels to different geographic areas. High-detail HD map data is processed for the immediate vicinity and planned route, while less critical areas use lower-detail data or are processed less frequently, optimizing the balance between route adaptability and processing efficiency
