Vehicle Access Control via Mobile Transmitter Presence Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle access systems require users to manually actuate a door handle, which can be inconvenient, especially when carrying items, as they need to free a hand to unlock the vehicle.
Innovation Solution
A method that detects a mobile identification transmitter within a specific access region around the vehicle, measures the user's presence, and automatically unlocks the vehicle after a predetermined duration, allowing users to terminate the process with a signal, enhancing convenience and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user manually actuates a door handle to unlock the vehicle, then the vehicle access system provides security control, but the user convenience deteriorates when hands are occupied with shopping items
Solution Approach 1:
The system automatically detects the user's approach via mobile identification transmitter and performs unlocking without requiring manual door handle actuation. The control device autonomously determines when to unlock based on detection of the mobile identification transmitter in the access region, eliminating the need for the user to manually operate the door handle.
Solution Approach 2:
The mechanical action of manually actuating the door handle is replaced by an electronic detection and control system. The system uses mobile identification transmitters, inquiry signals, and automated control logic to substitute the mechanical user action with an automated electronic process.
2Ease of operation
If the vehicle unlocks automatically when a mobile identification transmitter is detected in the access region, then user convenience improves, but the risk of accidental opening increases
Solution Approach 1:
The system performs preliminary detection and verification actions before executing the unlocking command. It first detects the mobile identification transmitter in the access region, then monitors for a predetermined period to confirm intentional user presence, and only then proceeds with unlocking if no termination signal is received.
Solution Approach 2:
The system continuously monitors the access region for the mobile identification transmitter and provides feedback through the unlocking control logic. It detects the presence signal, evaluates it against predetermined criteria, and adjusts the unlocking decision based on whether the transmitter remains in the access region for the required duration without termination.
3Reliability
If the system requires the user to stay in the access region for a predetermined duration before unlocking, then accidental opening is prevented, but the access time increases
Solution Approach 1:
The system uses periodic detection intervals to monitor the mobile identification transmitter's presence in the access region. Instead of continuous monitoring, it checks at predetermined time intervals whether the transmitter is still present, allowing the user to complete the authentication process relatively quickly while still ensuring intentional access.
Data Source
AI summary
A method for controlling at least one locking element of a vehicle is disclosed. A mobile identification transmitter is detected at a position in a certain access region around the vehicle. Furthermore, a user signal is output to a user carrying the mobile identification transmitter after the mobile identification transmitter has stayed at the position for a first predetermined duration. In addition, the at least one locking element is unlocked/opened after the mobile identification transmitter further stays at the position for a second predetermined duration after the user signal is output. For the targeted control of the automatic unlocking or opening of the vehicle door, the process of unlocking or opening is terminated if a termination signal from the user is detected within the second predetermined duration.
