Vehicle Accessory Geofence Control for Proximity Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems fail to efficiently manage vehicle functions based on the operator's proximity, leading to unnecessary energy consumption and potential safety hazards, as they often require location-independent signal transmission, which can result in premature activation of vehicle systems and decreased user satisfaction due to cumbersome operation.
Innovation Solution
Implementing a system where a vehicle accessory transmits location data to a mobile device, allowing it to generate virtual geofences, which enables intelligent control of vehicle functions only when the operator is near, thereby optimizing energy use and convenience by triggering functions like starting the vehicle or unlocking doors based on the operator's location and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle functions are activated based on location-independent signal transmission, then vehicle security and control reliability are improved, but energy consumption increases and user convenience deteriorates
Solution Approach 1:
The system performs preliminary actions by activating vehicle functions in advance based on geofence detection. When the mobile device enters the geofence area, the system proactively activates vehicle functions (such as unlocking doors or starting the engine) before the user actually reaches the vehicle, eliminating the need for manual activation and reducing energy waste from premature activation.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring the mobile device's location relative to the geofence boundaries. This real-time feedback enables the system to intelligently determine when to activate vehicle functions based on actual proximity, ensuring reliable control while optimizing energy consumption by avoiding unnecessary activations.
2Reliability
If vehicle functions are activated based on location-independent signal transmission, then control reliability is improved, but user convenience and operational efficiency deteriorate
Solution Approach 1:
The system enables self-service operation by automatically detecting when the user approaches the vehicle through geofence technology and autonomously activating the required vehicle functions. This eliminates the need for manual intervention, making the system more convenient and intuitive while maintaining reliable control through location-based triggering.
3Reliability
If location-independent signal transmission is used, then vehicle security is improved, but energy consumption increases due to premature activation
Solution Approach 1:
The system performs preliminary activation of vehicle functions only when the mobile device enters the geofence area, which is closer to the actual vehicle location. This preliminary action based on proximity reduces energy waste from premature activation while maintaining security through reliable location-based control.
Solution Approach 2:
The system dynamically adjusts vehicle function activation based on the mobile device's real-time location relative to the geofence. This dynamic approach ensures that functions are activated only when appropriate, optimizing energy consumption while maintaining security through adaptive control.

AI summary
A vehicle accessory can transmit a first signal to a mobile device, the first signal including a location of a vehicle. The mobile device can monitor its own location. The mobile device can assess whether one or more location-based criteria have been satisfied based on the location of the mobile device and the location of the vehicle. Upon determining that a location-based criterion has been satisfied, the mobile device can transmit a second signal to the vehicle accessory indicating that a function of the vehicle is to be controlled. Thus, for example, the mobile device can activate or de-activate vehicle features (e.g., door locking, vehicle defrosting, etc.) in a manner that capitalizes on efficient signal transmission.
