V2X Radio Theft Deterrent Using Dynamic BSM Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle theft remains a significant issue due to the limitations of existing technologies, including Vehicle-to-Anything (V2X) radios and car alarm systems, which struggle to effectively deter theft and conserve battery life when a vehicle is parked, leading to potential battery drainage and false alarms.
Innovation Solution
A deterrent system that integrates software into V2X radios and car alarm systems, utilizing Basic Safety Messages (BSMs) to notify nearby vehicles and smartphones of potential theft, while modifying the transmission rate to conserve battery life and prevent false alarms, by periodically pinging the alarm system and adjusting the transmission interval based on battery charge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the V2X radio transmits BSMs at a high periodic interval (e.g., every 0.10 seconds), then the security monitoring capability is improved, but the battery life deteriorates due to excessive energy consumption
Solution Approach 1:
The transmission interval is made dynamic rather than fixed. The system automatically adjusts the BSM transmission interval based on the vehicle's operational state: using shorter intervals (e.g., 0.10 seconds) when the vehicle is in motion or security risk is high, and longer intervals when parked or battery charge is low, thus optimizing both security monitoring and energy consumption
Solution Approach 2:
The system changes the transmission parameter (time interval) based on operational conditions. By monitoring vehicle state and battery charge level, the system modifies the BSM transmission frequency parameter to balance security requirements with energy conservation, preventing battery drainage while maintaining adequate security surveillance
2Reliability
If the V2X radio remains active continuously to detect criminal activity, then the detection capability is improved, but the battery drainage increases
Solution Approach 1:
Instead of continuous operation, the V2X radio performs periodic BSM transmissions at configurable intervals. The system transmits security status updates at regular periods (adjustable based on conditions) rather than continuously monitoring and transmitting, significantly reducing energy consumption while maintaining adequate detection capability for security events
Solution Approach 2:
The radio's operational state is made dynamic, switching between active transmission modes based on detected conditions. The system activates high-frequency monitoring only when security risks are detected or the vehicle is in use, and transitions to low-power periodic transmissions or standby mode when conditions are normal, optimizing the balance between detection capability and energy conservation

AI summary
The disclosure includes embodiments for theft deterrent for a connected vehicle using Basic Safety Message (BSM)-based Vehicle-to-Anything (V2X) communication. In some embodiments, a method includes receiving, by a V2X radio, a wireless message that is transmitted by a first connected vehicle whose ignition is disengaged. In some embodiments, the method includes determining, based on a payload of the wireless message, that the first connected vehicle is being subjected to criminal activity. In some embodiments, the method includes taking a remedial action responsive to determining that the first connected vehicle is being subjected to criminal activity. In some embodiments, the remedial action is operable to deter the occurrence of the criminal activity (i.e., stop the first connected vehicle from being stolen) or gather visual evidence of the criminal activity.
