Vehicle State Alerts via Ear-Mounted Terminal for Secure Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle notification systems fail to securely and effectively notify users that their vehicle is in an undesirable state, such as unlocked or unsecured, without alerting third parties, which can lead to security issues and inefficient battery charging.
Innovation Solution
A vehicle state presentation system that includes a terminal device with an ear-mounted unit for wireless communication with the vehicle, providing notifications through sound or vibration to the user when they leave the vehicle, ensuring the user is aware of the vehicle's state without third-party awareness, and allowing remote control to adjust the vehicle's state to a secure condition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If notification is performed through sound from speaker or visual display in the vehicle, then user can notice the vehicle state, but third party can also perceive the notification which compromises security
Solution Approach 1:
The patent introduces a mobile terminal as an intermediary device between the vehicle and the user. The vehicle sends notification signals to the mobile terminal, which then relays the notification to the user through the ear-mounted device. This intermediary approach allows the user to receive notifications without public displays or speakers in the vehicle, preventing third-party awareness while maintaining effective user notification.
2Loss of information
If notification is performed by call transmission or mail transmission to mobile terminal, then user can be notified, but user is likely not to notice the notification
Solution Approach 1:
The patent employs vibration feedback through the ear-mounted output unit to notify the user. The vibration provides a tactile sensation that is difficult to ignore, ensuring the user notices the notification immediately. This is combined with sound output to create a multi-sensory notification system that is far more effective than silent call or mail notifications.
3Ease of operation
If user leaves vehicle in non-secure state, then user convenience is maintained, but security risk increases and battery charging efficiency decreases
Solution Approach 1:
The system performs preliminary monitoring of vehicle state (door locking, window closing, lamp status) before the user leaves. When a non-secure state is detected, the system proactively sends notification signals to the user's mobile terminal before the user completely departs. This allows the user to return and correct the state (lock door, close window, turn off lamps) before leaving, thereby maintaining security and energy efficiency while preserving user convenience.

AI summary
A terminal device separate from a vehicle includes a receiver that receives a notification signal from the vehicle indicating that the vehicle is in a first state different from a second state, a notification unit that notifies a user of the terminal device of the first state based on the notification signal, an input unit that receives, from the user of the terminal device, an input commanding the first state to be maintained, and a transmitter that transmits a signal to the vehicle based on the input received by the input unit. The vehicle includes a control unit that performs control that maintains the first state after lapse of a predetermined time from a time that the notification unit of the terminal device notifies of the first state of the vehicle when a reception unit of the vehicle receives the signal transmitted from the transmitter within the predetermined time.
