Autonomous Vehicle Stop Location Control for Compliant Passenger Pickup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous driving vehicles face challenges in safely stopping near a prospective passenger due to legal, regulatory, or safety constraints, necessitating the search for an alternative location to allow boarding without violation.
Innovation Solution
A vehicle control system that includes a stop candidate location extraction unit, first and second movement time calculation units, and a standby time calculation unit to determine a suitable stop location based on the passenger's and vehicle's movement times, ensuring the stop time is within allowable limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the autonomous driving vehicle immediately stops near the prospective passenger, then the boarding efficiency is improved, but the vehicle may violate laws or safety regulations
Solution Approach 1:
The vehicle performs preliminary actions by calculating multiple candidate stop locations and their associated standby times before actually stopping. The system proactively identifies safe stopping positions that comply with regulations and prepares the boarding plan in advance, ensuring both efficiency and compliance are maintained from the outset rather than reacting after a violation occurs.
2Reliability
If the vehicle searches for a safe stop location away from the passenger, then compliance with laws is improved, but the boarding time increases
Solution Approach 1:
The system dynamically adjusts the stop location selection based on real-time calculations of standby times and regulatory constraints. Rather than using a fixed rule, the vehicle continuously evaluates multiple candidate locations and selects the optimal one that minimizes boarding time while ensuring compliance, making the stopping strategy adaptive and flexible.
Solution Approach 2:
The system changes the parameter of stop location selection by considering multiple candidate positions with different standby times. By varying the chosen stop location based on calculated parameters (standby time, distance from passenger, regulatory compliance), the system optimizes the balance between compliance and boarding efficiency.
3Reliability
If the vehicle stops at a location requiring the passenger to move further, then safety and legal compliance are improved, but the passenger convenience deteriorates
Solution Approach 1:
The system changes the parameter of stop location selection by considering multiple candidate positions with different standby times. By varying the chosen stop location based on calculated parameters (standby time, distance from passenger, regulatory compliance), the system optimizes the balance between compliance and boarding efficiency.

AI summary
A vehicle control device for controlling a vehicle is configured to stop in response to a request from a prospective passenger and allow the prospective passenger to board. The vehicle control device includes: a stop candidate location extraction unit configured to extract a candidate location for a stop location where the vehicle is to be stopped in order to allow the prospective passenger to board; a first movement time calculation unit configured to calculate a first movement time that is a time required for the prospective passenger to move to the candidate location; a second movement time calculation unit configured to calculate a second movement time that is a time required for the vehicle to move to the candidate location; a standby time calculation unit configured to calculate a standby time of the vehicle at the candidate location based on the first movement time and the second movement time; and a stop location determination unit configured to determine, when the standby time is equal to or shorter than a predetermined allowable stop time at the candidate location, the candidate location as the stop location.
