Automated Vehicle Stopping Position Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle stopping systems do not always select the most appropriate position for stopping, particularly when considering the width of the road shoulder and the presence of surrounding vehicles, which can affect traffic flow and safety.
Innovation Solution
A control apparatus for vehicles that includes sensors to detect the vehicle's surroundings and a travel controller to select a target stop position based on criteria such as vehicle speed, presence of surrounding vehicles, and positional relationships, allowing for automated stopping in a latitudinal direction relative to the vehicle's movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the vehicle stops at the position with the largest road shoulder width, then the influence on other vehicles is reduced, but the stopping position may not be the most appropriate considering surrounding vehicles and traffic conditions
Solution Approach 1:
The stopping position selection is made dynamic by continuously monitoring multiple parameters including vehicle speed, presence of surrounding vehicles, and positional relationships. The system adapts the target stop position based on real-time conditions rather than relying on a fixed criterion like maximum shoulder width alone.
Solution Approach 2:
The system changes the selection criteria from a single parameter (shoulder width) to multiple parameters including speed comparisons with threshold values, detection of surrounding vehicles, and analysis of positional relationships. This multi-parameter approach allows more appropriate stopping position selection.
2Device complexity
If the vehicle uses simple stopping criteria based only on road shoulder width, then the control system is simpler, but the stopping position selection is less accurate and reliable
Solution Approach 1:
The travel controller is designed to perform multiple functions: it not only selects stopping positions but also monitors vehicle speed, detects surrounding vehicles, and evaluates positional relationships. This multi-functional approach improves stopping accuracy without requiring entirely separate systems.
Solution Approach 2:
The system uses the vehicle's existing sensors and control capabilities to perform stopping position selection, leveraging already-available data about vehicle speed, position, and surrounding environment rather than requiring completely new detection systems.
3Ease of manufacture
If the vehicle does not consider surrounding vehicles and positional relationships, then the control system is simpler to implement, but the safety and appropriateness of stopping positions is compromised
Solution Approach 1:
The system continuously monitors the presence of surrounding vehicles and positional relationships, using this feedback information to adjust the target stop position selection. This feedback mechanism ensures safety without requiring overly complex manual intervention systems.

AI summary
A control apparatus for performing travel control of a vehicle comprises a sensor configured to detect a state around the vehicle, and a travel controller configured to perform travel control for automated driving based on a detection result of the sensor. The travel controller is configured to, in a case where a predetermined condition is satisfied, select a target stop position located in a latitudinal direction with respect to a direction in which the vehicle moves, according to selection criteria, and to stop the vehicle at the target stop position. The selection criteria include a comparison between a speed of the vehicle and a threshold speed.
