Vehicle Remote Control System Maintenance Warning Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle remote control systems cannot distinguish between a detached wire due to theft and intentional detachment during maintenance, leading to unnecessary warnings and activation restrictions.
Innovation Solution
A vehicle remote control system that includes a processing suppression unit to prevent warnings if the vehicle is in a maintenance state, even if voltage information cannot be acquired, by determining the vehicle's state through position information and control information, and suppressing warning transmission accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system transmits warnings when voltage information cannot be acquired, then vehicle security monitoring is improved, but false alarms during maintenance work increase
Solution Approach 1:
The system performs preliminary action by setting a maintenance flag before maintenance work begins. This flag is set in advance through terminal device operations or geofence detection, allowing the system to preemptively suppress warning transmissions during scheduled maintenance periods, thereby preventing false alarms while maintaining security monitoring capability.
Solution Approach 2:
The system applies dynamics by making the warning transmission function conditional and adjustable based on vehicle state. The processing suppression unit dynamically controls the warning unit's operation based on the maintenance flag status, allowing the system to adapt its behavior between normal operation (warnings enabled) and maintenance mode (warnings suppressed), resolving the contradiction between security monitoring and false alarm prevention.
2Object-generated harmful factors
If the system suppresses warnings during maintenance state, then false alarms are reduced, but the ability to detect actual abnormalities may be compromised
Solution Approach 1:
The system uses preliminary action by setting a time-limited maintenance flag that automatically expires after a predetermined period. This ensures that warning suppression is temporary and controlled, allowing the system to maintain reliability by automatically resuming normal warning transmission if maintenance is not completed within the expected timeframe, thus preventing permanent loss of abnormality detection capability.
Solution Approach 2:
The system implements feedback through the time-limited maintenance flag mechanism. The flag's automatic expiration provides a feedback loop that monitors maintenance progress and triggers a review of the suppression state, ensuring that the system returns to normal warning transmission mode if maintenance is delayed or abnormal conditions persist, thereby maintaining detection reliability.

AI summary
A vehicle remote control system includes a vehicle and a server configured to remote-control the vehicle via a communication device. The communication device comprises: an acquisition unit configured to acquire control information representing a control state of the vehicle from a control device configured to control the vehicle and voltage information from a power supply device configured to supply power to the vehicle; a transmission unit configured to transmit the control information and the voltage information to the server; a warning unit configured to, if the voltage information cannot be acquired, transmit a warning for notifying an abnormality of the vehicle to the server; and a processing suppression unit configured to, if the vehicle is in a maintenance state, suppress processing of the warning unit such that the warning is not transmitted.
