Mobile Vehicle Security Control via BCM Authentication Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle security systems do not effectively leverage mobile devices for comprehensive control of vehicle security features beyond basic functions like unlocking doors.
Innovation Solution
A method and device that utilize embedded software to monitor vehicle conditions and authentication signals, enabling/disabling security schemes via the body control module (BCM) based on predefined settings, using a mobile device to control features like brake activation, light shows, horn honking, and time/distance/speed limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile device control is expanded to comprehensive vehicle security features, then control versatility is improved, but system complexity increases
Solution Approach 1:
The mobile device is designed to perform multiple vehicle control functions through a single unified interface. The system enables the mobile device to control diverse security features including brake activation, accelerator pedal control, steering wheel lock, horn, lights, and alarm systems, replacing the need for multiple separate control devices or interfaces.
Solution Approach 2:
The system introduces an intermediary control architecture where the mobile device communicates with vehicle control modules through established communication protocols. This intermediary layer manages the complexity by handling authentication, signal translation, and coordination between the mobile device and various vehicle subsystems, shielding the user from underlying system complexity.
2Reliability
If authentication verification is required before enabling security schemes, then security reliability is improved, but operation time increases
Solution Approach 1:
The system performs authentication verification in advance before enabling security schemes. The mobile device must successfully authenticate with the vehicle system before any security control functions become active. This preliminary authentication ensures that only authorized users can access security features, preventing unauthorized activation while maintaining efficient operation once authenticated.
Solution Approach 2:
The system implements feedback mechanisms where the vehicle control system responds to authentication attempts from the mobile device. Successful authentication triggers immediate enablement of security schemes, while failed attempts prevent activation. This feedback loop ensures security reliability by confirming authorized access before allowing control, while the automated nature minimizes time loss.

AI summary
A method for mobile device control of vehicle security features that includes monitoring the status of predetermined vehicle conditions of a vehicle. In response to detecting the activation of one or more of the predetermined vehicle conditions, the method also includes monitoring the vehicle to detect an execution of one or more preset authentication verification signals for the vehicle. In response to detecting no execution of any preset authentication verification signals for the vehicle, the method also includes, based on the predetermined vehicle settings, sending a security enablement command to the body control module (BCM) of the vehicle via the embedded software, and based on the security enablement command, enabling one or more security schemes via the BCM.
