Vehicle Security Monitoring for Partial Unlock Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle security systems fail to effectively warn users of the danger of unauthorized access to parked vehicles when the vehicle is only partially unlocked, as they primarily focus on detecting unauthorized access rather than preventing it by alerting the user before an incident occurs.
Innovation Solution
A process and device that determine if a vehicle is partially unlocked, locate it using GPS or similar systems, compare this location to predetermined safe areas, and wirelessly transmit a warning to a mobile unit if it is not in a safe location, allowing for optical, acoustic, or haptic alerts and optional remote locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle is left partially unlocked for convenience, then ease of operation is improved, but security against unauthorized access deteriorates
Solution Approach 1:
The system performs preliminary monitoring of the vehicle's locked state and location before unauthorized access can occur. By continuously checking whether the vehicle is partially unlocked and comparing its location against predetermined safe areas, the system enables the user to lock the vehicle remotely before leaving, thus preventing rather than just detecting theft
Solution Approach 2:
The system establishes a feedback loop where the monitoring device continuously reports the vehicle's locked state and location to the user's mobile device. This real-time feedback enables the user to make informed decisions about locking the vehicle and provides ongoing security status updates, allowing corrective action before unauthorized access occurs
2Reliability
If the vehicle is fully locked for security, then security against unauthorized access is improved, but ease of operation deteriorates
Solution Approach 1:
The monitoring device automatically performs the security monitoring function without requiring continuous user intervention. The system self-monitors the vehicle's locked state, tracks its location, compares it with safe areas, and autonomously determines when to send warnings to the user's mobile device, freeing the user from manual security checks while maintaining high security
3Reliability
If remote monitoring and warning systems are implemented, then security against unauthorized access is improved, but device complexity increases
Solution Approach 1:
The monitoring device leverages existing multi-functional components: the vehicle's central locking system provides both locking functionality and locked-state detection, the GPS navigation system provides both navigation and location tracking, and the mobile device provides both communication and alert functions. By repurposing these existing systems rather than adding dedicated components, the solution achieves enhanced security while minimizing additional device complexity
Solution Approach 2:
The system uses the user's existing mobile device as an intermediary between the vehicle's monitoring system and the user. Rather than requiring a dedicated complex alarm system with multiple components, the mobile device serves as a simple mediator that receives location and locked-state data and delivers warnings, significantly reducing overall system complexity while maintaining effective security monitoring

AI summary
The invention concerns a process and assistance system for warning of an unauthorized access to a parked vehicle. The process includes a first step for providing a communication as to whether the vehicle is at least partially unlocked. In a second step, in the case of an affirmative communication, the transmission of the current location of the vehicle takes place. In a third step, a comparison is made between the current location with at least one predetermined home location. In a fourth step, in the case in which the current location does not correspond with at least one home location, a wireless transmission of a warning signal to a mobile unit is given. In a fifth step, following the receipt of the warning signal by the mobile unit, a warning that is perceptible optically and/or acoustically and/or haptically is undertaken.
