Vehicle Central Locking Auto-Unlock via Geoposition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing central locking systems for motor vehicles are complex and do not adequately balance safety and comfort, particularly in scenarios where automatic unlocking is desired without manual intervention.
Innovation Solution
A method for operating a central locking apparatus that uses a portable mobile terminal to emit its geoposition, which is detected and evaluated by the vehicle's control device to determine if it is within a predetermined region, thereby automatically unlocking the system when the terminal is within that region, enhancing safety and comfort by ensuring only authorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic locking is activated when driving above a minimum speed, then safety during driving is improved, but ease of operation deteriorates as manual unlocking is required
Solution Approach 1:
The central locking system automatically unlocks itself when the vehicle stops and a portable terminal is detected in the predetermined region, eliminating the need for manual intervention by the driver or occupants. The system serves itself by monitoring its own locked state and autonomously transitioning to unlocked state based on detected conditions.
Solution Approach 2:
The control device continuously receives geoposition data from portable terminals and evaluates whether the terminal is within the predetermined region. This feedback loop enables the system to automatically transition from locked to unlocked state when appropriate conditions are met, replacing manual operation.
2Ease of operation
If automatic unlocking is implemented without manual intervention, then ease of operation is improved, but device complexity increases due to additional detection and control mechanisms
Solution Approach 1:
The control device performs multiple functions: it monitors vehicle speed for automatic locking, receives geoposition data from portable terminals, evaluates whether terminals are in the predetermined region, and triggers automatic unlocking. By consolidating these functions in a single control device, the patent avoids adding separate complex subsystems.
Solution Approach 2:
The portable terminal acts as an intermediary carrier that conveys geoposition information to the vehicle's detection device. This intermediary approach allows the system to obtain location data without requiring direct complex communication infrastructure or additional sensors in the vehicle.
3Ease of operation
If geoposition detection is used for automatic unlocking, then ease of operation and comfort are improved, but measurement precision requirements increase to ensure accurate region detection
Solution Approach 1:
Instead of requiring high-precision global positioning, the patent defines a local predetermined region (such as near the vehicle) where unlocking should occur. The system evaluates whether the portable terminal is within this local area, reducing the measurement precision requirements compared to global coordinate-based systems.
Solution Approach 2:
The system uses a predetermined region with a radius that extends beyond the exact vehicle position. This excessive coverage area ensures that even if geoposition measurement has some error, the terminal will still be detected as within the region when the user is near the vehicle, maintaining reliability without requiring high precision.

AI summary
The invention relates to a method for operating a central locking apparatus of a motor vehicle, which is locked by a central locking system of the central locking apparatus as a result of driving above a minimum speed threshold, and is then decelerated to below the minimum speed, wherein in order to subsequently unlock the central locking system, an instantaneous geoposition (GP) emitted from a portable mobile terminal, is first received by means of a detection device of the central locking apparatus. The emitted instantaneous geoposition (GP) of the portable mobile terminal is subsequently evaluated by means of a control device of the central locking apparatus, wherein when evaluating the instantaneous geoposition (GP), the control device checks whether the emitted instantaneous geoposition (GP) is within a delimited, predetermined region, which is stored in the control device. The central locking system is finally unlocked when the emitted instantaneous geoposition (GP) is within the delimited, predetermined region.
