Vehicle Movement Authorization for In-Car and Remote Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to appropriately determine user execution authority for vehicle functions when the user is both inside and outside the vehicle, leading to potential time-consuming authentication processes and risks of information leakage.
Innovation Solution
A control system and method that includes a control device in the vehicle and a user-carried information terminal, which perform separate determination processing for movement control based on the user's presence, ensuring secure and efficient execution of vehicle functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If personal authentication is executed through communication between smartphone and vehicle for remote operation, then user can be authenticated outside the vehicle, but authentication time increases and information leakage risk arises
Solution Approach 1:
The system performs authentication in advance by determining user execution authority before the remote operation begins. The control device stores authentication results and uses them during remote operation, eliminating the need for real-time communication authentication and thus reducing authentication time.
Solution Approach 2:
The authentication function is extracted from the communication process between smartphone and vehicle. Instead of performing authentication through communication during remote operation, the system separates authentication into a preliminary determination process that stores results locally, thereby reducing both authentication time and information leakage risk.
2Adaptability or versatility
If personal authentication is executed through communication between smartphone and vehicle for remote operation, then user can be authenticated outside the vehicle, but information leakage risk increases
Solution Approach 1:
The authentication function is extracted from the communication process between smartphone and vehicle. Instead of performing authentication through communication during remote operation, the system separates authentication into a preliminary determination process that stores results locally, thereby reducing both authentication time and information leakage risk.
Solution Approach 2:
The control device acts as an intermediary that performs determination processing locally rather than through direct smartphone-vehicle communication. This intermediary approach allows authentication to be performed without transmitting sensitive personal information between devices, thus reducing information leakage risk.
3Reliability
If separate determination processing is performed for inside and outside vehicle operations, then user execution authority can be appropriately determined, but system complexity increases
Solution Approach 1:
The control device performs multiple functions: it determines user execution authority for both inside-vehicle and outside-vehicle operations, stores authentication results, and executes movement control based on these results. This multi-functional approach consolidates what could be separate systems into a single control device, maintaining reliability while managing complexity.
Solution Approach 2:
The system merges the determination processing for inside-vehicle and outside-vehicle operations into a single control device. Instead of having separate authentication systems for different operation modes, the control device handles both scenarios through unified determination processing and result storage, simplifying the overall system architecture.

AI summary
A system of a moving object includes a controller and an information terminal carriable by the user of the moving object. The controller is configured to execute first control for moving the moving object in a state where a user is present in the moving object; and execute second control for moving the moving object in a state where the user is not present in the moving object. In response to a first request, the controller executes first processing for determining execution authority of the user for the first control, and executes the first control based on a result of the first processing, and in response to a second request, the information terminal executes second processing for determining execution authority of the user for the second control, and causes the moving object to execute the second control based on a result of the second processing.
