Vehicle Communication Device Timing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle communication systems face issues with increased communication costs and inconvenient notification of failed vehicle accessory manipulations due to reliance on mobile communication networks and data relay stations, leading to inaccurate or missed notifications when the user is near the vehicle.
Innovation Solution
A vehicle communication device that establishes a wireless communication line with a mobile terminal, generates and transmits output timing specifying information to notify the user of accessory manipulation states at appropriate times, ensuring timely notification of failed manipulations by defining the output timing as when the user separates from the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If wireless communication is used to transmit manipulation state information from the vehicle to the mobile terminal, then communication costs are reduced, but notification accuracy deteriorates due to variable radio wave areas and accidental transmissions when the user is near the vehicle
Solution Approach 1:
The system performs preliminary detection of the communication state between the vehicle and mobile terminal before transmitting manipulation state information. By detecting whether the mobile terminal is within the radio wave area in advance, the system determines the appropriate output timing for notifications, ensuring accurate delivery only when the user has actually separated from the vehicle.
Solution Approach 2:
The system continuously monitors the communication state and uses this feedback to dynamically adjust the notification timing. By detecting changes in radio wave area and communication connectivity, the system adapts the output timing of manipulation state information to match the actual separation of the user from the vehicle, preventing both accidental and missed notifications.
2Ease of operation
If the communication line is established between the vehicle and mobile terminal, then information transmission is enabled, but the system cannot distinguish between intentional user presence and accidental proximity
Solution Approach 1:
The system performs preliminary detection of communication state changes to determine when the mobile terminal has actually separated from the vehicle. By monitoring the establishment and dissolution of communication lines in advance, the system can accurately identify the timing of user separation, distinguishing intentional absence from accidental proximity.
