Bluetooth Vehicle Access Threshold Control to Prevent False Triggers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle control methods using Bluetooth technology suffer from low intelligentization and accuracy due to the short wavelength of Bluetooth signals, which can be affected by human bodies or objects, leading to frequent and incorrect triggering of unlocking/locking operations.
Innovation Solution
A vehicle control method and apparatus that adjust the parameter thresholds for controlling vehicle operations based on the strength or distance of the Bluetooth signal, increasing the difference between unlocking and locking thresholds to prevent frequent triggering, thereby improving the accuracy and intelligentization of vehicle control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If Bluetooth signal strength threshold is set close to triggering value, then vehicle control responsiveness is improved, but false triggering frequency increases
Solution Approach 1:
The patent dynamically adjusts the Bluetooth signal strength threshold based on vehicle state and environmental conditions. When the vehicle is stationary or moving slowly, a lower threshold is used to reduce false triggering. When the vehicle is moving quickly or in environments with signal interference, a higher threshold is applied to maintain reliability while still responding to legitimate access attempts.
Solution Approach 2:
The threshold parameter is made dynamic rather than fixed, allowing the system to adapt to changing conditions. The threshold automatically adjusts based on vehicle speed, movement state, and signal stability, enabling the system to maintain optimal responsiveness without false triggering across different operating scenarios.
2Measurement precision
If parameter threshold difference between unlocking and locking is small, then control sensitivity is improved, but frequent incorrect triggering occurs
Solution Approach 1:
The patent implements dynamic threshold adjustment where the difference between unlocking and locking thresholds varies based on vehicle state. When the vehicle is stationary, a smaller threshold difference maintains high sensitivity. When the vehicle is moving or signal conditions are poor, a larger threshold difference prevents false triggering while still allowing legitimate operations.
Solution Approach 2:
The threshold difference is made dynamic, automatically expanding or contracting based on real-time conditions. This allows the system to maintain high control sensitivity when needed while preventing frequent incorrect triggering during movement or signal interference, resolving the contradiction between sensitivity and reliability.
3Measurement precision
If Bluetooth wavelength is short, then signal precision is improved, but susceptibility to blocking by objects increases
Solution Approach 1:
The patent adjusts the signal strength threshold parameter based on detected blocking conditions. When objects are detected between the vehicle and electronic device (reducing signal strength), the threshold is dynamically adjusted to account for the blocking, maintaining precision while compensating for the harmful blocking effect.
Solution Approach 2:
The patent converts the harmful effect of signal blocking into useful information. By detecting reduced signal strength caused by blocking objects, the system adjusts its threshold accordingly, using the blocking effect itself as a trigger for parameter adjustment to maintain accurate control.
