Automated Vehicle Return Control for Left-Behind Belongings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automatic driving vehicles, users often leave belongings behind when exiting in a hurry, and distinguishing personal items from those of other passengers is difficult, leading to significant time spent retrieving lost items through lost-and-found offices.
Innovation Solution
A driving support apparatus and system that includes a communication device and processor to send a return command for the vehicle to move back to the user's exit location when the required return time is less than an available return time, calculated based on the user's exit time and passenger destination information, allowing for efficient retrieval of left-behind belongings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle returns to the exit location, then belongings can be retrieved, but the vehicle is away from the passenger's destination
Solution Approach 1:
The system dynamically determines whether returning to exit location is appropriate by evaluating the relationship between predicted return time and elapsed time since user exit. Only when predicted return time is within the available window does the system command the return, optimizing between belongings retrieval and minimizing unnecessary travel
Solution Approach 2:
The determination unit acts as an intermediary between the user's return request and the vehicle's actual return action. It mediates by evaluating multiple conditions (passenger destination, current location, time constraints) and only permits return when conditions are satisfied, preventing unnecessary vehicle movements
2Ease of operation
If the system allows return requests at any time, then user convenience is improved, but vehicle efficiency decreases due to unnecessary returns
Solution Approach 1:
The system implements feedback control by continuously monitoring vehicle location, passenger destination, and elapsed time since user exit. The determination unit uses this feedback to dynamically adjust whether return requests are approved, preventing unnecessary returns while maintaining user convenience when returns are appropriate
Solution Approach 2:
The system dynamically evaluates return requests based on real-time conditions rather than uniformly approving or rejecting all requests. The determination unit adjusts its decision-making based on the relationship between predicted return time and elapsed time, optimizing vehicle efficiency while maintaining user convenience

AI summary
A driving support apparatus that includes a communication device configured to communicate with a vehicle-mounted device installed in a vehicle that is under automatic driving control and a mobile terminal of a user of the vehicle, and a processor configured to send, upon receiving a return request for moving the vehicle to an exit location at which the user has exited the vehicle, from the mobile terminal through the communication device, a return command for moving the vehicle to the exit location to the vehicle-mounted device through the communication device, when a return time required to move the vehicle to the exit location is less than an available return time, the available return time being calculated based on an expected arrival time at which the vehicle is expected to arrive at a destination of a passenger different from the user.
