Vehicle Data Transmission via Geofence Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for communicating vehicle data require manual intervention and are inefficient, leading to increased time and costs during service operations.
Innovation Solution
A method that automatically determines if a vehicle is in a predefined service facility area, using existing communication interfaces and position signals to transmit vehicle data to a collection device, which can then make this data available to the service facility, potentially using radio networks or RFID for verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual connection using a diagnostic connector is used to read vehicle data, then data can be obtained during service, but the process requires manual intervention and increases time and costs
Solution Approach 1:
The system automatically transmits vehicle data to the service facility before the vehicle arrives or upon arrival, so that data is already available when the service technician begins work. This preliminary data transmission eliminates the need for manual data reading during the service appointment, reducing service time and costs.
2Productivity
If automatic data transmission is implemented, then service efficiency improves, but additional communication infrastructure and position determination systems are required
Solution Approach 1:
The invention utilizes existing multi-functional components in modern vehicles: the radio device serves both entertainment/communication purposes and data transmission to the service facility; the navigation system provides position information for geofence detection while also serving its primary navigation function. This multi-functionality approach avoids adding dedicated separate systems, thereby limiting the increase in device complexity.
3Loss of time
If position-based automatic transmission is used, then data is available promptly upon arrival, but position determination and geofence verification systems are needed
Solution Approach 1:
The navigation system's position determination capability is repurposed for geofence verification. The same GPS receiver and positioning algorithms used for navigation also provide the position data needed to determine whether the vehicle has entered the service facility's geofence area, eliminating the need for a separate position determination system.
4Ease of manufacture
If existing radio and navigation systems are utilized for data transmission, then no additional hardware costs are required, but the systems must support bidirectional communication and position signaling
Solution Approach 1:
The system dynamically adapts the communication capabilities of existing radio and navigation systems for data transmission purposes. The radio device transitions between its standard entertainment/communication modes and a diagnostic data transmission mode. The navigation system dynamically provides position data to the control unit for geofence verification, enabling the system to flexibly meet communication requirements without hardware modifications.
Data Source
AI summary
A method for communicating vehicle data relating to a vehicle automatically determines whether a vehicle is in a predefined surrounding area of a service facility. If this has been detected, a predefined set of vehicle data is provided via a communication interface of the vehicle for transmission to a vehicle data collection device. The set of vehicle data received by the vehicle data collection device is at least partially made available to the service facility.
