Vehicle Passive Locking Prevention via Remote Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automotive security systems with passive locking features can inadvertently lock a remote control inside a vehicle, causing inconvenience and cost to the user, as they passively lock the vehicle even if the remote control is left inside.
Innovation Solution
A security system with a passive locking prevention device that detects the presence of a remote control using an electromagnetic field disturbance device or RFID tag, preventing the vehicle from passively locking and alerting the user if the remote control is within the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If passive locking is enabled to automatically lock doors after user exits, then vehicle security is improved, but the risk of locking remote control inside the vehicle increases
Solution Approach 1:
The detection device performs preliminary detection of the remote control's presence inside the vehicle before the passive locking function is executed. If the remote control is detected inside the vehicle, the system prevents the automatic locking action from occurring, thereby avoiding the harmful effect of locking the remote control inside while still maintaining the security benefit of automatic locking when appropriate.
2Measurement precision
If detection range extends beyond vehicle interior, then remote control detection reliability improves, but false detection of external objects increases
Solution Approach 1:
The detection device is configured with a detection range that is specifically oriented and limited to the vehicle interior space. The detection field is localized to the region where the remote control would be if left inside the vehicle, rather than extending broadly to detect objects outside the vehicle. This localized detection approach maintains high reliability for detecting remote controls inside the vehicle while avoiding false detections of external objects.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents the vehicle from automatically locking when the remote control is inside, ensuring the user's convenience by alerting them if the vehicle is not passively locked, thus avoiding the scenario of locking the remote control inside.
Implementation Method 1
The detection device preferably has a detection range extending only to the inside of the vehicle. The detection device can be an electromagnetic field disturbance device.
Implementation Method 2
The remote control further includes an emission device, such as an RFID tag. The passive locking prevention device comprises a detection device preferably located within the passenger compartment of the vehicle for detecting an emission from the emission device.
Data Source
AI summary
A security system is disclosed having a base controller, a base transceiver, a remote control, and a passive locking prevention device. The passive locking prevention device includes a detection device preferably located within the passenger compartment of the vehicle for detecting the remote control. The detection device preferably has a detection range extending only to the inside of the vehicle. The passive locking prevention device is configured such that the vehicle will not passively lock when the passive locking prevention device detects the remote control. The passive locking prevention device can be connected to the base controller via a wired or wireless connection. The remote control can contain an emission device that emits a detectable signal by the detection device, and upon such detection, the vehicle is prevented from locking. The system can visibly or audibly alert a vehicle owner if the vehicle is not passively locked.
