Innovation Solution
A vehicle control system that allows users to customize distance thresholds for locking and unlocking doors through wireless communication between a vehicle control apparatus and a portable device, using signal strength measurements to set personalized thresholds for Walk Away Lock and Welcome Entry functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed distance thresholds are used for door locking and unlocking, then the system is simple to implement, but the system cannot be customized to meet different user needs
Solution Approach 1:
The system automatically determines the distance threshold by having the user perform simple operations (approaching the vehicle, getting in, or getting out) while the system measures the signal strength at those moments. This self-service approach eliminates the need for manual threshold configuration while still providing customization based on user behavior patterns.
Solution Approach 2:
The system continuously monitors the signal strength between the portable device and the vehicle control apparatus, and uses this feedback to automatically set appropriate distance thresholds. The feedback loop allows the system to adapt to different users and situations without requiring manual intervention.
2Ease of operation
If manual configuration of distance thresholds is implemented, then user customization is enabled, but the operation becomes complex and time-consuming
Solution Approach 1:
The system performs threshold configuration automatically without requiring users to manually input values or navigate complex menus. Users simply need to perform natural actions like approaching or leaving the vehicle, and the system handles the measurement and configuration process automatically, minimizing both operational complexity and time investment.
Solution Approach 2:
The system performs the threshold setting action automatically during normal vehicle operations (when the user approaches, enters, or exits the vehicle). This preliminary automation of the configuration process eliminates the need for separate setup procedures, making the system easy to operate from the start.
3Adaptability or versatility
If fixed threshold values are used, then the system is reliable and secure, but the system cannot adapt to different user preferences and situations
Solution Approach 1:
The system continuously monitors signal strength and uses this feedback to dynamically adjust distance thresholds while maintaining security. The feedback mechanism ensures that door control decisions are based on real-time conditions and authenticated user actions, preserving reliability while enabling adaptability to different users and situations.

Implementation Method 1
The portable device measures a signal strength of a second signal received from the vehicle control apparatus
Data Source
AI summary
A vehicle control system includes a vehicle control apparatus, a first portable device, and a second portable device. The first portable device transmits a first signal to the vehicle control apparatus based on the fact that a first operation by a user is performed on the second portable device. When the vehicle control apparatus receives the first signal from the first portable device, the vehicle control apparatus intermittently transmits a second signal to the first portable device. The first portable device measures a signal strength of the second signal received from the vehicle control apparatus, based on the fact that a second operation by the user is performed on the second portable device after the first operation. The vehicle control apparatus or the first portable device sets, as a distance threshold, a distance between the first portable device and the vehicle calculated from the measured signal strength.
