Automated Vehicle Stop-Space Selection for Pick-Up and Drop-Off
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated driving systems lack an effective method to determine an appropriate stop space in predetermined pick-up and drop-off areas, which affects user convenience and time efficiency.
Innovation Solution
An automated driving system that includes a processor to control the vehicle's stop position based on surrounding situation information, prioritizing upstream areas for drop-off and downstream areas for pick-up to ensure efficient user access and vehicle departure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the automated driving vehicle stops in the standard stop space, then the stop position is fixed and predictable, but the stop space may not be available when other vehicles are present
Solution Approach 1:
The system dynamically adjusts the stop position based on real-time availability. When the standard stop space is unavailable, the processor automatically selects alternative stop spaces in the upstream or downstream areas, making the stop position flexible rather than fixed.
Solution Approach 2:
The system changes the stop position parameter based on the availability of the standard stop space. The processor determines whether the standard stop space is available and switches between the standard position and alternative positions (upstream or downstream) accordingly.
2Loss of time
If the automated driving vehicle stops in the upstream area for drop-off, then the user can quickly get off the vehicle, but the vehicle cannot utilize the standard stop space efficiently
Solution Approach 1:
The system applies different stop position strategies based on the local situation. When the standard stop space is unavailable, it selectively uses upstream areas for drop-off operations to minimize user disembarkation time, while preserving downstream areas for pick-up operations to maintain vehicle turnover efficiency.
Solution Approach 2:
The processor determines in advance whether the standard stop space is available before the vehicle arrives. If unavailable, it pre-determines the alternative stop position (upstream or downstream) based on whether the operation is drop-off or pick-up, allowing the vehicle to stop immediately without delay.
3Loss of time
If the automated driving vehicle stops in the downstream area for pick-up, then the vehicle can depart quickly after user boards, but the user has to wait longer for the vehicle to arrive
Solution Approach 1:
The system applies different stop position strategies based on the local situation. When the standard stop space is unavailable, it selectively uses downstream areas for pick-up operations to minimize vehicle departure time and waiting time, while preserving upstream areas for drop-off operations to maintain user convenience.
Solution Approach 2:
The processor determines in advance whether the standard stop space is available before the vehicle arrives. If unavailable, it pre-determines the alternative stop position (upstream or downstream) based on whether the operation is drop-off or pick-up, allowing the vehicle to stop immediately without delay.
4Device complexity
If the automated driving system uses a fixed stop position, then the control is simple, but the system cannot adapt to unavailable stop spaces
Solution Approach 1:
The system dynamically adjusts the stop position based on real-time availability. When the standard stop space is unavailable, the processor automatically selects alternative stop spaces in the upstream or downstream areas, making the stop position flexible rather than fixed.
Solution Approach 2:
The system changes the stop position parameter based on the availability of the standard stop space. The processor determines whether the standard stop space is available and switches between the standard position and alternative positions (upstream or downstream) accordingly.

AI summary
A pick-up and drop-off area, which is a predetermined area in which an automated driving vehicle stops to pick up or drop off a user, includes a downstream area existing downstream of a standard stop space and an upstream area existing upstream of the standard stop space. An automated driving system controls the automated driving vehicle so as to stop in a target stop space in the pick-up and drop-off area. When the standard stop space is available, the standard stop space is set as the target stop space. When the standard stop space is not available for the automated driving vehicle to stop to drop off the user, the automated driving system searches for an upstream available space in the upstream area and preferentially sets the upstream available space as the target stop space.
