Automatic Driving Control Device Route Change Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated driving systems do not adequately address route changes during ongoing automated driving, potentially causing discomfort to drivers and failing to prevent unintended changes in automated driving sections, especially when using auto-rerouting functions or manual intervention.
Innovation Solution
An automated driving control device that includes a navigation system and control unit to determine whether a route change is permissible based on differences in automated driving sections, allowing changes only if intended by the driver, and prohibiting changes if they would alter the automated driving section, thereby maintaining the current route if not permitted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If auto-rerouting function is used to change route automatically during automated driving, then route guidance flexibility is improved, but driver comfort deteriorates due to unintended changes in automated driving sections
Solution Approach 1:
The system applies preliminary anti-action by proactively preventing unwanted route changes. Before allowing a route change via auto-rerouting, the determination unit checks whether the new route's automated driving sections match the current route's sections. If they differ, the route change is blocked, thereby preventing the adverse effect of unintended changes in automated driving sections before they can occur.
Solution Approach 2:
The system implements feedback by continuously monitoring route changes and their impact on automated driving sections. When a route change is detected, the determination unit compares the automated driving sections of the current and new routes, and provides feedback by either permitting or prohibiting the route change based on this comparison, ensuring driver comfort is maintained.
2Adaptability or versatility
If route change is allowed during automated driving, then navigation adaptability is improved, but reliability of automated driving section deteriorates due to unintended changes
Solution Approach 1:
The system prevents reliability deterioration by proactively blocking route changes that would alter automated driving sections. The determination unit performs a preliminary check before allowing any route change, ensuring that only routes with identical automated driving sections are permitted, thereby maintaining the reliability and stability of the automated driving section.
Solution Approach 2:
The system uses feedback control by continuously monitoring route changes and comparing the automated driving sections. When a route change is detected, the feedback mechanism determines whether to permit or prohibit the change based on whether the automated driving sections remain consistent, thus maintaining reliability while allowing appropriate navigation adaptability.
3Extent of automation
If automated driving mode is performed in any generated route, then driving automation extent is improved, but control precision deteriorates due to lack of route change validation
Solution Approach 1:
The system enhances control precision through feedback by implementing a determination unit that validates route changes. Before the automated driving control unit executes a route change, the determination unit provides feedback by comparing the automated driving sections of the current and new routes, ensuring that only validated route changes are permitted, thereby maintaining high control precision.
Solution Approach 2:
The system applies preliminary action by performing route change validation before executing the route change. The determination unit checks whether the new route's automated driving sections match the current route's sections before the automated driving control unit implements the change, ensuring that control precision is maintained through advance validation.

AI summary
Provided is an automatic driving control device advantageous for a vehicle or the like in which a route can be changed during movement to a destination. An automatic driving control device, wherein a navigation device is provided with a route generation unit for generating a second route which is difference from a first route on the basis of predetermined conditions, and a determination unit for determining whether to change from the first route to the second route when an automatic driving permissible interval included in the second route is different from the automatic driving permissible interval included in the first route. When the route has been determined by the determination unit to be changeable from the first route to the second route, a control unit executes an automatic driving mode in the automatic driving permissible interval included in the second route.
