Remote Flashing Bypass Module for Vehicle Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern vehicle security systems, such as transponder-based immobilizers, complicate the installation of remote starter apparatuses, reducing car security if a bypass module is required, as they necessitate the presence of an RF key or chip within the vehicle, which can be exploited by thieves.
Innovation Solution
A method and system for remotely flashing an external module by electronically transferring and processing firmware or software to enable communication with the vehicle's security device, allowing secure engine starting without compromising the vehicle's security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a bypass module is installed to allow remote starter to work with transponder-based immobilizers, then the remote starter functionality is enabled, but the vehicle security level is reduced
Solution Approach 1:
The patent introduces a bypass module as an intermediary device that mediates between the remote starter and the transponder-based immobilizer system. This module captures and processes the RF signal from the key, extracting the identification code and transmitting it to the immobilizer system through authorized channels, thereby enabling remote start functionality while maintaining security protocols
Solution Approach 2:
The bypass module segments the security verification process by separating the RF signal capture function from the authentication function. The module captures the RF signal independently, then transmits only the necessary identification data to the immobilizer system, allowing remote operation without compromising the core security verification mechanism
2Reliability
If an RF key or chip is required to be present within the vehicle for the engine to start, then the immobilizer security is maintained, but the ease of operation for remote starters is reduced
Solution Approach 1:
The bypass module serves as an intermediary that captures the RF signal from the key outside the vehicle and transmits the authentication data through authorized channels, eliminating the need for the key to be physically present inside the vehicle while maintaining security
Solution Approach 2:
The patent replaces the mechanical requirement of physical key insertion and presence within the vehicle with an electronic RF signal capture and transmission system, allowing remote operation while maintaining the security integrity of the immobilizer system
3Adaptability or versatility
If a bypass module is installed to enable external module communication with security device, then the remote starter works seamlessly, but the device complexity increases
Solution Approach 1:
The bypass module is designed with multi-functionality, serving as both an RF signal capturer and an authentication data transmitter. By consolidating these functions into a single device, the system achieves external module communication capability without proportionally increasing overall system complexity
Solution Approach 2:
The bypass module autonomously captures the RF signal, processes the authentication data, and transmits it to the immobilizer system without requiring external intervention or complex configuration, thereby reducing the operational complexity despite adding communication capability
