Remote Vehicle Starting Prohibition System for Drunk Driving Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for preventing drunk driving rely solely on the user's willpower, which is not always effective in preventing accidents, as they may still choose to drive after consuming alcohol.
Innovation Solution
A system that includes a server connected to vehicles, user terminals, and designated driver service companies, where users can remotely prohibit their vehicle from starting using an application, ensuring only a third party can drive after a designated period, thereby reducing the likelihood of drunk driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanism relies only on user willpower to prevent drunk driving, then the system remains simple and easy to operate, but the effectiveness in preventing drunk driving is insufficient
Solution Approach 1:
The patent introduces a server as an intermediary between the vehicle and the user. The server receives prohibition requests from user terminals and manages the starting prohibition status remotely. This mediator approach allows the system to achieve effective drunk driving prevention through centralized management without requiring complex modifications to the vehicle itself, resolving the contradiction between reliability and device complexity.
Solution Approach 2:
The system segments the drunk driving prevention function into separate components: user terminal for initiating prohibition, server for managing prohibition status, and vehicle for executing starting prohibition. This segmentation allows each component to remain relatively simple while the integrated system achieves high reliability in preventing drunk driving.
2Reliability
If the vehicle starting is prohibited remotely through a server, then the effectiveness in preventing drunk driving is improved, but the ease of operation deteriorates due to requiring third-party cancellation
Solution Approach 1:
The system applies preliminary anti-action by pre-prohibiting vehicle starting before the user potentially drives while drunk. The user can remotely prohibit starting before leaving or before consuming alcohol, and the prohibition remains in effect until a third party cancels it. This preliminary measure ensures that even if the user intends to drive, the vehicle cannot be started, thus improving reliability while maintaining operational control through predefined cancellation mechanisms.
3Reliability
If the prohibition period is extended to ensure safety, then the reliability of preventing drunk driving is improved, but the loss of time for legitimate use increases
Solution Approach 1:
The system implements feedback mechanisms where the server notifies relevant parties about the prohibition status and cancellation status. The third party who cancels the prohibition receives confirmation, and the user can check the status through the user terminal. This feedback loop ensures that the prohibition period is appropriately managed - extended enough to ensure safety but reduced promptly when legitimate use is needed, thus balancing reliability and time loss.

AI summary
A system includes a unit to obtain starting prohibition information including first user identification information and vehicle identification information; a prohibiting unit to, when a first user identified by the first user identification information is a user permitted to prohibit a vehicle from starting, prohibit a vehicle identified by the vehicle identification information in the starting prohibition information from starting; a unit to obtain prohibition cancel information including second user identification information and vehicle identification information; and a unit to, when a second user identified by the second user identification information is a user permitted to cancel prohibition of starting of a vehicle and a vehicle identified by the vehicle identification information in the prohibition cancel information is the vehicle prohibited by the prohibiting unit from starting, cancel the prohibition of the starting of the vehicle identified by the vehicle identification information in the prohibition cancel information.
