Vehicle Access Identifier Buffering Commands During Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automatic access and start systems for motor vehicles cannot simultaneously manage communication for identifier authentication and processing of commands from the identifier's bearer during data exchange phases, leading to potential misinterpretation of command execution.
Innovation Solution
The system includes a hands-free identifier that stores commands entered by the bearer during detection and authentication phases and transmits them after authentication is complete, allowing the system to process these commands without repetition and preventing misinterpretation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle transmits interrogation signals at regular intervals for identifier authentication, then the authentication process can be completed, but commands entered by the bearer during data exchange phases may be lost or misinterpreted
Solution Approach 1:
The system performs preliminary actions by detecting and buffering commands during the authentication data exchange phases before the authentication is complete. The buffer temporarily stores these commands so they are not lost during the authentication process, and processes them afterward, thus preventing information loss while maintaining authentication reliability.
2Ease of operation
If the system processes commands immediately during data exchange phases, then user responsiveness is improved, but authentication accuracy may be compromised
Solution Approach 1:
The system detects and buffers commands in advance during the authentication process without processing them immediately. This preliminary buffering ensures authentication accuracy is maintained while still capturing all user commands for subsequent processing, thus resolving the contradiction between responsiveness and accuracy.
Solution Approach 2:
The buffer acts as an intermediary between command input and command processing. It temporarily holds commands during authentication, allowing the authentication process to complete accurately while preserving all user commands for later processing, thus maintaining both authentication precision and operational responsiveness.
3Productivity
If multiple interrogation signals are transmitted in quick succession, then authentication efficiency is improved, but the probability of command loss during communication increases
Solution Approach 1:
The system performs preliminary detection and buffering of commands during the rapid authentication exchange, ensuring that even if commands are entered during the quick succession of interrogation signals, they are captured and stored in the buffer before processing, thus preventing loss while maintaining high authentication speed.

AI summary
The invention concerns an automatic access and starting system for a motor vehicle, comprising an on-board access management system and at least one identifier (3) such as an electronic key, the access management system being configured to detect and authenticate the identifier (3) when it is close to the vehicle (1), the identifier (3) being configured to emit an authentication signal in response to an interrogation signal emitted by the management and access system, the identifier (3) comprising a memory for storing an instruction relative to a command issued by the carrier of the identifier (3) if this command is issued during the phase of detection and authentication by the on-board system, the instruction being stored temporarily in order for the identifier to be able to emit a signal related to the command when the detection and authentication phase is complete.
