Mobile Telematics Control Using Vehicle Identifier Trip Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telematics systems face challenges in accurately and timely detecting trip starts, leading to delayed activation of safety features and increased exposure during initial moments of a trip, particularly due to reliance on GPS-based methods and user-dependent activation, which can result in missed events like crashes.
Innovation Solution
A mobile device-based system that uses a unique vehicle identifier, such as a Bluetooth Device Address, to detect vehicle presence without requiring pairing, enabling immediate activation of telematics features by switching to a high-power mode upon trip start detection, thereby enhancing sensor precision and reducing battery consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If GPS-based methods are used to detect trip start, then device compatibility is improved, but detection timeliness deteriorates
Solution Approach 1:
The mobile device performs preliminary actions by continuously monitoring for vehicle system identifiers and preparing to switch to vehicle mode immediately upon detection. The device pre-loads necessary sensor configurations and telematics features, enabling instantaneous activation without GPS processing delays when a trip start is detected through identifier recognition.
2Use of energy by moving object
If user-dependent activation is used, then power consumption is reduced, but reliability of safety feature activation deteriorates
Solution Approach 1:
The mobile device serves itself by automatically detecting vehicle system identifiers and autonomously switching to vehicle mode without requiring user intervention. The device self-configures sensors and activates telematics features based on identifier detection, ensuring reliable safety feature activation while consuming power only when necessary, thereby eliminating the trade-off between automatic and manual activation.
3Reliability
If telematics features are activated continuously, then detection reliability is improved, but battery consumption increases
Solution Approach 1:
The mobile device dynamically adjusts its operational state by switching between non-vehicle mode and vehicle mode based on real-time detection of vehicle system identifiers. In non-vehicle mode, sensors operate at low power or remain inactive. Upon identifier detection, the device transitions to vehicle mode, activating high-precision sensors and telematics features only when needed, thereby maintaining detection reliability while minimizing battery consumption through adaptive power management.
Data Source
AI summary
The method performed by a mobile device includes receiving, by a communication receiver of the mobile device over a communication channel, a system identifier that uniquely identifies a vehicle system of a vehicle, detecting a vehicle trip start condition based on a pre-defined association between the system identifier and the mobile device, based on detecting the vehicle trip start condition, operating the mobile device in a vehicle mode comprising activating at least one telematics feature, and detecting vehicle telematics data generated by a telematics data sensor.
