Trip End Estimation Using Mobile Device Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for monitoring vehicle trips lack sufficient information to accurately determine when a trip has concluded, often relying on assumptions rather than actual data.
Innovation Solution
A system that includes a processor and memory configured to receive data from a vehicle and a mobile device, estimating the end of a trip based on updated data from the mobile device when the vehicle stops transmitting, using floating car data and other information to generate a trip log.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the system relies solely on vehicle transmission data at periodic intervals, then the system complexity is reduced, but the accuracy of determining trip end time deteriorates
Solution Approach 1:
The patent introduces a mobile device as an intermediary component that bridges the gap between vehicle transmission data and accurate trip end detection. The mobile device independently monitors vehicle status (through sensors, GPS, or connection status) and provides complementary data when vehicle transmission is unavailable, thereby resolving the contradiction between system simplicity and measurement accuracy.
Solution Approach 2:
The system performs preliminary actions by having the mobile device continuously monitor and record trip-related data in advance, so that when vehicle transmission stops, the trip end can be accurately determined using pre-collected data from the mobile device, rather than waiting for the next scheduled vehicle transmission.
2Loss of time
If the system uses assumptions to determine trip end, then the processing time is reduced, but the reliability of trip logging deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously compares data from the vehicle and mobile device to determine trip status. When vehicle transmission stops, the system uses feedback from mobile device data (such as continued movement detection or connection loss) to reliably confirm trip end, rather than relying on simple assumptions, thus maintaining both time efficiency and reliability.
3Loss of information
If the system collects data from both vehicle and mobile device, then the information completeness improves, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing the mobile device to serve multiple functions: it acts as a backup data source, a trip end detector, and a complement to vehicle transmission. This multi-functionality justifies the added complexity by providing comprehensive information coverage without requiring separate dedicated components for each function.
Data Source
AI summary
Systems and methods for estimating an end of a vehicle trip. The system includes a memory that stores instructions for executing processes for estimating the end of the vehicle trip and a processor configured to execute the instructions. The instructions cause the processor to: receive first data from each of a vehicle and a mobile device connected to the vehicle, the first data being received from the vehicle at periodic intervals; receive updated first data and second data from the mobile device when the mobile device is disconnected from the vehicle; upon failing to receive the first data from the vehicle at a next interval, estimate the end of the vehicle trip based on the updated first data and the second data from the mobile device; and generate a trip log with the estimated end of the vehicle trip.
