Autonomous Vehicle Stop Request Routing Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic driving vehicles face challenges in determining whether to stop at a passenger's requested location en route to their destination, especially when multiple passengers have different destinations, requiring a system to manage stop requests and route adjustments efficiently.
Innovation Solution
A driving support apparatus and system that includes a communication device and processor to determine stop locations, generate driving routes, and calculate stop times, allowing for appropriate vehicle stops based on passenger requests, while considering the routes and arrival times of other passengers, and dispatching vehicles when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the automatic driving vehicle stops at the passenger's requested location, then the passenger's need is satisfied, but the arrival time at the destination is delayed
Solution Approach 1:
The system dynamically adjusts the vehicle's route and stopping behavior based on real-time conditions. When a stop request is received, the control device calculates whether the stop time is within the allocated time budget, and dynamically modifies the driving route to include the stop location if feasible, otherwise maintains the original route to meet the arrival deadline.
2Adaptability or versatility
If the vehicle accommodates stop requests from multiple passengers with different destinations, then passenger satisfaction is improved, but the route planning complexity increases
Solution Approach 1:
The system segments the passenger group into those who will alight at the stop location and those who will continue to the original destination. It then generates separate driving routes: a first driving route from the current location to the stop location, and a second driving route from the stop location to the original destination, allowing independent optimization of each segment.
Solution Approach 2:
The control device pre-calculates the stop time required at the stop location and compares it with the allocated time before committing to the route modification. This preliminary assessment prevents unnecessary route changes that would fail to meet arrival deadlines.
3Reliability
If the vehicle maintains the original driving route to meet the target arrival time, then punctuality is ensured, but passenger requests for stops are not fulfilled
Solution Approach 1:
The system implements a feedback mechanism where the control device continuously monitors the relationship between calculated stop time and allocated time. Based on this feedback, it decides whether to modify the driving route to accommodate the stop request or to maintain the original route to ensure punctual arrival, and communicates this decision to the passenger.

AI summary
A driving support apparatus includes a communication device configured to communicate with a vehicle-mounted device installed in a vehicle that's under automatic driving control; and a processor configured to determine, upon receiving a stop request by a passenger who is riding in the vehicle from a mobile terminal of the passenger or the vehicle-mounted device of the vehicle through the communication device, a stop location in accordance with the stop request; generate a driving route of the vehicle from a present location of the vehicle to the stop location; and calculate a stop time required to stop the vehicle at the stop location, based on the driving route to the stop location, and when the stop time is less than an allocated time for the stop request, send a stop command for moving the vehicle to the stop location to the vehicle-mounted device of the vehicle through the communication device.
