Vehicle Security System with Smart Device Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle security systems are often bypassed or compromised, allowing unauthorized access to vehicles, and there is a need for an independent security system that can authorize access and prevent unauthorized use.
Innovation Solution
A vehicle security system that combines a vehicle security device with a user's smart device for bi-directional communication, providing a two-step authentication process using wireless signals to control vehicle functions such as door locks, alarms, and engine immobilization, offering an additional layer of security beyond traditional keys and fobs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional vehicle security systems (keys and fobs) are used, then ease of operation is maintained, but reliability of security is compromised due to bypassing and unauthorized access
Solution Approach 1:
The security system is divided into separate functional modules: a sensor module for detecting access attempts, a communication module for wireless messaging, and a control module for executing security actions. This segmentation allows each component to be optimized independently while maintaining overall system reliability without excessive complexity.
Solution Approach 2:
A wireless communication intermediary (smart device) is introduced between the user and the vehicle security system. This intermediary enables two-step authentication and provides an additional layer of verification without requiring direct physical interaction with traditional keys or fobs, thereby enhancing security reliability while maintaining ease of operation.
2Object-affected harmful factors
If existing OEM vehicle security systems are bypassed, then unauthorized access is enabled, but the alarm is not activated and undue attention is avoided
Solution Approach 1:
The system performs preliminary authentication actions through wireless message exchange before granting physical access. The smart device and vehicle security system verify each other's credentials in advance, preventing unauthorized access attempts from succeeding while allowing legitimate users convenient access without forced entry tools.
Solution Approach 2:
The system implements continuous feedback monitoring of vehicle access parameters through sensors that detect door handles, lock mechanisms, and other access points. This real-time feedback enables the system to identify bypass attempts and activate appropriate security responses, maintaining both security effectiveness and operational convenience.

AI summary
A vehicle authorization system with a transmitter/receiver capable of activating vehicle functions operably connected to the vehicle, a wireless transmitter/receiver for an authorized vehicle operator that receives communications from the vehicle transmitter/receiver, a sensor in the vehicle security transmitter/receiver that detects at least one vehicle access parameter via an electronic signal, wherein the vehicle transmitter/receiver communicates with the wireless transmitter/receiver responsive to the sensor detecting a second signal associated with the access parameter to affirm a verification signal from the wireless transmitter/receiver that upon verification permits vehicle access by the operator or upon improper or no response activates a vehicle function to prevent access or vehicle operation. The invention consists of a vehicle security device that can both monitor and control vehicle systems, and a user's smart device. The invention is combined with the existing vehicle keys and fobs to provide a two-step authentication.
