Vehicle Stop Position Control for Door Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems fail to ensure that vehicles can stop at positions that are suitable for users to easily get in or out, as the determined stop positions may not consider the availability of space around the vehicle doors or the presence of obstacles.
Innovation Solution
A vehicle control device with a stop position determination module that uses map data to identify safe and obstacle-free areas within a predetermined distance from the destination, ensuring a suitable space for users to enter or exit the vehicle, and an abnormality detection module that adjusts the stop position based on detected issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle stops at a position determined by map information specifying non-stop regions, then the vehicle can avoid stopping in prohibited areas, but the stop position may not be suitable for users to easily get in or out of the vehicle
Solution Approach 1:
The system performs preliminary actions by determining the stop position in advance while considering both map information and door space requirements. The stop position determination unit calculates the appropriate stop position before the vehicle arrives, ensuring that the vehicle will stop at a location that satisfies both prohibition rules and user accessibility needs.
Solution Approach 2:
The system adds another dimension to stop position determination by considering the spatial relationship between the vehicle door and surrounding obstacles. Instead of only considering the vehicle's position on the road, the system evaluates the three-dimensional space around the door to ensure sufficient clearance for user access.
2Stability of the object's composition
If the vehicle stops at a position determined by state-amount representative value and variability, then the vehicle can stop at positions with stable environmental conditions, but the stop position may still not provide adequate space for users to get in or out
Solution Approach 1:
The system performs preliminary determination of the stop position by evaluating both environmental stability and door space requirements simultaneously. The stop position determination unit calculates the appropriate stop position in advance, ensuring that the vehicle will stop at a location that satisfies both stability criteria and user accessibility needs.
Solution Approach 2:
The system adds another dimension to stop position determination by evaluating the spatial clearance around the vehicle door. Instead of only considering environmental stability metrics, the system also assesses the three-dimensional space required for user access to the vehicle.
3Ease of operation
If the vehicle stops closer to the destination to improve user convenience, then users can more easily access the vehicle, but the vehicle may stop in unsafe regions or near obstacles
Solution Approach 1:
The system performs preliminary determination of the stop position by evaluating both user accessibility and safety requirements. The stop position determination unit calculates the appropriate stop position in advance, ensuring that the vehicle will stop at a location that provides sufficient door space while avoiding obstacles and unsafe regions.
Solution Approach 2:
The system adds another dimension to stop position determination by evaluating the spatial clearance around the vehicle door. Instead of only considering proximity to destination, the system assesses the three-dimensional space required for user access while maintaining safety margins from obstacles.
4Adaptability or versatility
If the vehicle stops at positions without considering door space requirements, then the vehicle can stop at any position within the allowed region, but the space for users to get in or out may be blocked by obstacles
Solution Approach 1:
The system performs preliminary determination of the stop position by evaluating both flexibility and door space requirements. The stop position determination unit calculates the appropriate stop position in advance, ensuring that the vehicle will stop at a location that allows for obstacle-free user access.
Solution Approach 2:
The system adds another dimension to stop position determination by evaluating the spatial clearance around the vehicle door. Instead of only considering whether the position is within allowed regions, the system assesses the three-dimensional space required for user access to the vehicle.

AI summary
A vehicle control device includes: a stop position determination portion configured to determine a stop position at which a vehicle is stopped for a user to get in the vehicle or get off the vehicle so that a space for the user to get in or get off the vehicle is secured around a door of the vehicle, the door being used by the user when the user gets in or gets off the vehicle; and a driving controlling portion configured to perform an automatic driving control on the vehicle so that the vehicle stops at the stop position.
