Solution Overview

Problem

Current vehicle telematics systems lack effective means to detect unauthorized movement, which can lead to theft and delayed recovery of stolen vehicles.

Innovation Solution

A method and apparatus utilizing a vehicle telematics unit with a sensor to measure and monitor the resting angle of a vehicle, sending an alert if an unauthorized change in angle exceeds a predetermined threshold or persists beyond a set time, leveraging wireless communication to notify authorities or owners.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If vehicle telematics systems monitor multiple parameters continuously, then detection capability improves, but energy consumption increases

Engineering Contradiction:

Improveunauthorized movement detection capabilityVSAvoidtelematics unit energy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system implements periodic monitoring of vehicle resting angle at predetermined intervals rather than continuous monitoring. The telematics unit wakes from low-power mode at scheduled times to check the angle sensor, maintaining detection capability while significantly reducing energy consumption during idle periods.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system establishes a baseline resting angle measurement when the vehicle is first parked and remains stationary. This preliminary measurement is stored and used for comparison in subsequent monitoring cycles, enabling the system to detect deviations without requiring continuous active sensing.

Inventive Principle:

Principle #10Preliminary action

2Loss of time

If the system sends alerts for every angle change, then response time improves, but false alarms increase

Engineering Contradiction:

Improvealert response timeVSAvoidalert accuracy

Core Design Contradiction:

Loss of timeVSReliability

Solution Approach 1:

The alert threshold is made dynamic rather than fixed. The system adapts the threshold based on the specific vehicle context, considering factors like parking duration, location characteristics, and environmental conditions. This allows the system to maintain high sensitivity for genuine theft attempts while tolerating normal variations such as uneven parking surfaces.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback mechanisms where alert history and vehicle response patterns are analyzed to refine future alert behavior. If repeated minor angle changes occur without triggering actual theft, the system learns to adjust its sensitivity, reducing false alarms while maintaining effective detection of genuine threats.

Inventive Principle:

Principle #23Feedback

AI summary

A system and method for detecting unauthorized vehicle movement that includes measuring a resting angle of a vehicle using a vehicle sensor; thereafter, detecting a change in the measured resting angle of the vehicle; determining that the detected change is not authorized; and sending an alert message based on the determination via a vehicle telematics unit.
