Autonomous Route Generation Integrating Map and Sensor Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing route generation systems face challenges in generating reliable routes for regions undetectable by vehicle-mounted detectors and rely heavily on outdated or incomplete map data, leading to incomplete or unreliable route control for autonomous vehicles.
Innovation Solution
A route generation device and method that combines autonomous route generation based on real-time surrounding information with map route acquisition from a database, integrating the two to create a highly reliable and complete route by compensating missing parts and adjusting weights based on information accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If route is generated only based on map data, then route coverage is improved, but route reliability deteriorates due to outdated or incomplete map data
Solution Approach 1:
The patent combines map route information with autonomous route information detected by vehicle-mounted detectors to generate integrated route information. This merging approach allows the system to benefit from both the comprehensive coverage of map data and the real-time accuracy of autonomous detection, resolving the contradiction between route coverage and route reliability.
2Measurement precision
If route is generated only based on vehicle-mounted detector information, then route accuracy in detectable regions is improved, but route completeness deteriorates due to undetectable regions
Solution Approach 1:
The patent integrates autonomous route information from vehicle-mounted detectors with map route information to create comprehensive integrated route information. This combination compensates for the limitations of autonomous detection in undetectable regions while maintaining the high accuracy of detector-based routing in detectable regions, thus resolving the contradiction between route accuracy and route completeness.
3Adaptability or versatility
If autonomous route generation is used, then real-time adaptability is improved, but system complexity increases due to integration requirements
Solution Approach 1:
The patent introduces an integrated route information generator as an intermediary component that combines map route information and autonomous route information. This mediator integrates multiple information sources and generates unified integrated route information, reducing the complexity of direct integration between multiple systems while maintaining real-time adaptability.

AI summary
A route generation device includes: an autonomous route generator configured to generate, based on surrounding information around an own vehicle detected by a vehicle-mounted detector, an expected autonomous route along which the own vehicle is to travel; a map route acquirer configured to acquire an expected map route along which the own vehicle is to travel based on map data; and an integrated route generator configured to generate an integrated route using the autonomous route and the map route.
