Automotive Network Anti-Theft Control for Remote Ignition Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-theft systems for vehicles lack remote control functionality and rely on electromechanical devices, which are costly to install and maintain, and do not provide a high level of security as they can be physically circumvented or require direct user intervention.
Innovation Solution
A software-based anti-theft security device that connects directly to the automotive network, using modular hardware with various wireless communication technologies to send commands to the vehicle's embedded systems, preventing ignition or limiting vehicle performance, and remains active even if the device is removed, eliminating the need for electromechanical switches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electromechanical devices are used for anti-theft systems, then the system can physically block vehicle operation, but the installation and maintenance costs increase and the system can be physically circumvented
Solution Approach 1:
The patent replaces electromechanical blocking devices with software-based control that operates through the vehicle's existing electronic network. Instead of using mechanical locks or electrical relays to physically block ignition, the system injects malicious code or alters software parameters to prevent the engine control unit from authorizing startup, thereby substituting mechanical/electrical hardware with software-based security mechanisms
Solution Approach 2:
The patent introduces an intermediary software layer that operates between the user input and the vehicle's ignition system. This software intermediary monitors and controls ignition authorization by manipulating electronic signals and software parameters, acting as a mediator that can remotely enable or disable vehicle operation without requiring direct physical intervention in the ignition mechanism
2Reliability
If electromechanical devices are used for anti-theft systems, then the system can block vehicle operation, but remote control functionality is lost and user intervention is required
Solution Approach 1:
The patent implements self-service functionality where the anti-theft system automatically monitors vehicle status, detects unauthorized attempts, and executes blocking actions without requiring continuous user intervention. The system includes automated alert mechanisms that notify owners of suspicious activity and can autonomously engage software-based locks, enabling the system to serve itself in maintaining security
Solution Approach 2:
The patent introduces a remote communication intermediary that connects the vehicle's software-based anti-theft system to the owner's device. This intermediary enables remote control by transmitting vehicle status and receiving authorization commands, allowing the owner to enable or disable the anti-theft function from a distance without requiring physical presence or direct interaction with the vehicle
3Reliability
If software-based control is implemented on the automotive network, then remote control and high security are achieved, but the device requires integration with embedded systems
Solution Approach 1:
The patent implements a universal software-based control system that can operate across different vehicle platforms by interfacing with the automotive network's existing communication protocols. The system is designed to be platform-agnostic, capable of injecting and executing security functions through standard OBD ports and common diagnostic interfaces, thereby reducing integration complexity while maintaining high security across diverse vehicle types
Solution Approach 2:
The patent replaces complex physical integration of electromechanical devices with software-based integration that leverages the vehicle's existing electronic architecture. By substituting hardware installation with software deployment through standard communication interfaces, the system reduces integration complexity while achieving comparable or superior security through the vehicle's own embedded systems

AI summary
ROAD VEHICLES ANTI-THEFT SECURITY DEVICE BASED ON AUTOMOTIVE EMBEDDED SYSTEMS SOFTWARE presents itself as an anti-theft device for the automotive field, acting as a tool to aid in the recovery and protection of the asset. In technical terms, it is an electronic device connected to an embedded automotive network, which can take actions autonomously or receive remote commands to avoid the next ignition cycles and/or adding limitations regarding the performance and nominal working load of the protected vehicles. The modular hardware allows it to be coupled with different expansion boards that allows the adoption of several wireless data transmission technologies such as GPRS, GSM, LTE, WiFi, Bluetooth, LoRa, ZigBee, SigFox and satellite communication. Due to its technical features, the effect of anti-theft activation via software remains active even when the transgressor removes the device completely from the vehicle. The Over-The-Air (OTA) update feature makes it possible to load new security strategies in the hardware, consequently increasing the difficulty of carrying out vehicle's theft. These features differs it from the alternatives found in the state of the art, the current solutions performs the anti-theft task with the aid of electromechanical device, normally the well-known relays. In addition, the proposed device supports performance limitation and remote shutdown of the protected vehicle, features that accredit it to the post of invention.
