Vehicle Control Device for Autonomous Getting-Off Position Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passengers in autonomously travelable vehicles face difficulty in designating an appropriate getting-off position near the destination, especially when they are not well-informed about the traffic conditions, as all places around the destination can be potential getting-off positions.
Innovation Solution
A vehicle control device equipped with a vehicle controller, image display, and getting-off position detector that displays the periphery of the destination, including prohibited stopping regions, allows passengers to input their desired getting-off position, and the vehicle moves to stop at a suitable location based on passenger input, ensuring safety and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all places in the vicinity of the destination are designated as potential getting-off positions, then the passenger has more freedom to choose, but the passenger has difficulty in quickly recognizing an appropriate place to get off
Solution Approach 1:
The display device displays images of the destination periphery with different visual characteristics for different regions. Specifically, regions where stopping is permitted are displayed with one visual style while regions where stopping is prohibited are displayed with a different visual style (e.g., hatched patterns or different colors). This local differentiation helps passengers quickly identify appropriate getting-off positions among all potential locations, resolving the contradiction between providing freedom of choice and enabling easy designation.
2Adaptability or versatility
If the passenger designates a getting-off position within a prohibited stopping region, then the passenger's choice is respected, but the vehicle cannot stop at the designated position due to traffic regulations
Solution Approach 1:
The system performs preliminary identification of prohibited stopping regions by analyzing periphery information (such as road markings, signs, or map data) before the passenger designates a getting-off position. The display device then visually indicates these prohibited regions to the passenger. This preliminary action prevents the passenger from designating positions where stopping is prohibited, thereby maintaining both passenger choice and the reliability of being able to stop at the designated position.
Solution Approach 2:
When the passenger designates a getting-off position, the system provides immediate feedback by checking whether the designated position is within a prohibited stopping region. If it is, the system notifies the passenger and prevents the vehicle from stopping there. This feedback mechanism ensures that passenger choices are respected only when they comply with traffic regulations, maintaining both adaptability and reliability.
3Loss of time
If the vehicle stops at a position close to the destination, then the passenger's destination requirement is met, but the vehicle may stop in a prohibited region
Solution Approach 1:
The system pre-identifies prohibited stopping regions in the vicinity of the destination using periphery information detection and map data analysis. Before the vehicle approaches the destination, the display device shows these prohibited regions to the passenger. This preliminary identification allows the vehicle to plan its stopping approach in advance, ensuring it stops close to the destination while avoiding prohibited regions, thus minimizing both time loss and regulatory violations.

AI summary
A vehicle control device that controls a vehicle configured to transport a passenger to a destination by autonomous traveling, the vehicle control device includes a vehicle controller configured to control operation of the vehicle, an image display configured to display an image of a periphery of the destination to the passenger via an output device, and a getting-off position detector configured to detect a desired getting-off position designated by the passenger via an input device. The image shows a region where stopping is prohibited, and the vehicle controller is configured to cause the vehicle to stop at the desired getting-off position.
