Automated Vehicle Stop Control for Passenger-Aware Pickup Approach
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passengers, especially vulnerable pedestrians and those carrying heavy baggage, experience discomfort and fear due to the unpredictable movement of automated vehicles approaching and stopping in pick-up and drop-off areas, as existing automated drive systems do not account for passenger types, leading to inadequate convenience and safety.
Innovation Solution
An automated drive device and method that identifies passenger types before approaching a pick-up and drop-off area, adjusting its behavior to perform specific approaching and stopping operations, such as varying the entry position and alignment of the vehicle entrance, to match the feeling and convenience of the passengers, prioritizing vulnerable pedestrians and those with heavy baggage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the vehicle approaches the pick-up and drop-off area at a fixed position and manner, then the automated drive operation is simple and efficient, but vulnerable pedestrians feel afraid and uncomfortable due to unpredictable vehicle movement
Solution Approach 1:
The system performs passenger type recognition before the vehicle reaches the pick-up and drop-off area, allowing the automated drive device to pre-adjust its approaching behavior. This preliminary identification enables the vehicle to switch to appropriate approaching patterns (first or second pattern) in advance, reducing passenger fear while maintaining operational efficiency.
Solution Approach 2:
The automated drive device dynamically switches between different approaching patterns based on the identified passenger type. The system adjusts vehicle speed, positioning, and approaching trajectory in real-time according to whether vulnerable pedestrians are present, making the vehicle behavior adaptable rather than fixed, thereby reducing passenger discomfort without excessive complexity.
2Object-affected harmful factors
If the vehicle varies its approaching position and direction, then passenger comfort and safety are improved, but the stopping precision and alignment with waiting positions may be compromised
Solution Approach 1:
The system determines the appropriate approaching pattern in advance based on passenger type recognition. By pre-planning the approaching trajectory and stopping position, the system ensures that even when varying the approach, the vehicle will stop at the correct position aligned with the waiting position, maintaining stopping precision while improving passenger comfort.
Solution Approach 2:
The system changes operational parameters (approach speed, positioning coordinates, trajectory angle) based on the identified passenger type. When vulnerable pedestrians are detected, the system adjusts these parameters to create a gentler approach pattern, while still ensuring the vehicle stops at the precise location aligned with the waiting position through coordinated control.

AI summary
An automated drive device that automatically stops a vehicle in a pick-up and drop-off area in which a passenger gets and off the vehicle includes at least one processor and at least one memory that stores a program and information to be read by the at least one processor. The processor is configured to acquire the type of the passenger before the vehicle reaches the pick-up and drop-off area as a first process. The processor is configured to change a behavior for stopping the vehicle in the pick-up and drop-off area in accordance with the type of the passenger as a second process.
