Vehicle Travel Mode Transition Using Map-Environment Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving systems fail to smoothly transition from general travel assistance to specific region travel assistance when a vehicle enters a predetermined area, such as transitioning from general road travel to private land travel.
Innovation Solution
A vehicle control device and method that includes an external environment recognition unit and a storage unit to determine a travel condition based on map information and external environment information, allowing smooth transition to a second travel mode when the vehicle enters a determination area, enabling travel in a travelable area based on stored map information and real-time environmental data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vehicle uses general travel assistance on general roads, then the vehicle can travel autonomously using basic routing information, but the vehicle cannot smoothly transition to specific region travel assistance when entering predetermined areas
Solution Approach 1:
The system performs preliminary actions by determining travel conditions and preparing for mode transition before the vehicle actually enters the predetermined area. The control device evaluates whether external environment information and map information satisfy matching conditions in advance, allowing smooth transition to specific region travel assistance when the vehicle enters the travelable area.
Solution Approach 2:
The system implements dynamic adaptability by enabling the vehicle to switch between first travel mode (general travel assistance) and second travel mode (specific region travel assistance) based on real-time conditions. The travel mode is not fixed but dynamically adjusted according to whether the vehicle is in a predetermined area and whether travel conditions are satisfied, making the system adaptable to different operational contexts.
2Reliability
If the vehicle transitions to specific region travel assistance using stored route history, then the vehicle can navigate private lands effectively, but the transition from general travel assistance is not smooth
Solution Approach 1:
The system uses feedback mechanisms by continuously monitoring whether external environment information obtained by the external environment recognition unit and map information stored in the storage unit satisfy a predetermined matching condition. This feedback loop ensures that transition to the second travel mode occurs only when conditions are appropriate, maintaining navigation reliability while ensuring smooth transition.
Solution Approach 2:
The control device acts as an intermediary that mediates between general travel assistance and specific region travel assistance. It evaluates travel conditions including matching between external environment information and map information, and only transitions to the second travel mode when both the matching condition is satisfied and the vehicle enters the travelable area, ensuring smooth and reliable mode transition.
3Reliability
If the vehicle uses external environment recognition and map information matching to determine travel conditions, then the vehicle can safely navigate specific regions, but the system requires complex information processing
Solution Approach 1:
The system applies local quality by using different information processing approaches for different regions. In general areas, basic travel assistance is provided, but when the vehicle enters a predetermined area, the system activates more sophisticated processing that matches external environment information with stored map information. This localized enhancement ensures safe navigation in specific regions without requiring complex processing everywhere.
Solution Approach 2:
The system changes processing parameters based on location and context. When determining travel conditions in predetermined areas, the control device evaluates whether external environment information and map information satisfy matching conditions. This parameter-based approach (checking matching conditions) provides reliable navigation in specific regions while keeping the overall system manageable by only activating detailed processing when needed.

AI summary
A vehicle control device includes: a processor configured to perform travel control for moving a vehicle to a target position and to transition between a first and a second travel mode, the vehicle including an external environment recognition unit and a storage unit configured to store map information on a region including a predetermined determination area and a travelable area where traveling in the second travel mode is possible. The processor determines, in response to the vehicle entering the determination area while the vehicle is traveling in the first travel mode, a travel condition in the second travel mode, the travel condition including whether external environment information and the map information satisfy a predetermined matching condition, transition, in response to determining that the travel condition is satisfied and the vehicle enters the travelable area, to the second travel mode, and cause the vehicle to travel in the second travel mode.
