Autonomous Route Control Using History Switching by Travel Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving systems lack the ability to generate optimal travel routes that balance reliance on stored route history with real-time environmental data, particularly in complex or unfamiliar environments.
Innovation Solution
A control device and method that switches between using stored route history and real-time external environment recognition data based on the specific conditions of the travel area, employing separate control units for different sections of the journey to optimize route generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a travel route is generated based on stored route history, then the vehicle can efficiently navigate familiar areas, but the system lacks adaptability to generate optimal routes in complex or unfamiliar environments
Solution Approach 1:
The system dynamically switches between two operational modes: using stored route history for familiar areas and generating routes based on real-time external environment recognition data for unfamiliar or complex areas. This dynamic adaptation allows the navigation system to optimize performance based on the specific characteristics of the current travel area, thereby resolving the contradiction between navigation efficiency and route generation adaptability.
2Stability of the object's composition
If the system always uses stored route history for navigation, then route consistency is maintained, but the system cannot adapt to changing environmental conditions or optimize routes in real-time
Solution Approach 1:
The navigation space is segmented into two categories: familiar areas where stored route history is applicable and unfamiliar or complex areas where real-time route generation is required. This segmentation allows the system to maintain route consistency in familiar areas while enabling real-time optimization in areas where stored history is insufficient, thus resolving the contradiction between route consistency and real-time adaptability.
3Adaptability or versatility
If the system switches between route history usage and real-time route generation, then adaptability improves, but system complexity increases
Solution Approach 1:
The system performs preliminary classification of travel areas into familiar and unfamiliar categories before route generation. By pre-establishing this classification framework and the corresponding control logic, the system simplifies the decision-making process during actual navigation, reducing the operational complexity despite the enhanced adaptability provided by dual-mode route generation.

AI summary
A control device for a moving object, the control device includes: an external environment recognition unit configured to acquire external environment recognition data of the moving object; a storage unit configured to store a route history of the route used when the moving object moves to a target position; and a movement control unit configured to perform movement control of moving the moving object to the target position along a section to the target position. The movement control unit switches a usage mode of the route history in the movement control in a first section included in the section in which it is difficult to move without referring to the route history and a second section that is included in the section and that is different from the first section, and generates a travel route.
