Vehicle Diagnostic Device Using Identification Data for Manufacturer-Specific Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for requesting diagnostic data from vehicles are limited by standardized connections, which restrict the amount of data that can be retrieved, such as emission-related data, and do not allow for efficient communication of various diagnostic information.
Innovation Solution
A method and system that utilize a device to request identification data from a vehicle, which is then used to retrieve configuration data from a server for manufacture-specific communication, enabling the retrieval of a wide range of diagnostic data, including sensor information, by switching between standardized and non-standardized communication protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If standardized connection protocols (e.g., ISO15031) are used for vehicle diagnostic communication, then compatibility and ease of operation are improved, but the quantity and variety of retrievable diagnostic data are limited
Solution Approach 1:
The diagnostic device is designed to support multiple communication protocols simultaneously, enabling it to function with both standardized connections (ISO15031) and manufacturer-specific protocols. This multi-functionality allows the device to access a broader range of diagnostic data while maintaining compatibility with standard communication interfaces.
Solution Approach 2:
The device acts as an intermediary between the vehicle's control units and the user's communication device (e.g., smartphone). It retrieves identification data from the vehicle, obtains appropriate configuration data from a server, and then uses this configuration to enable access to manufacturer-specific diagnostic data that would otherwise be inaccessible through standardized protocols alone.
2Adaptability or versatility
If manufacturer-specific communication protocols are implemented, then the variety of diagnostic data accessible is improved, but device complexity and configuration requirements increase
Solution Approach 1:
The system performs preliminary actions by automatically retrieving identification data from the vehicle and then using this data to obtain the appropriate configuration data from a server before actual diagnostic operations begin. This pre-configuration process eliminates the need for manual setup and reduces user burden despite the complexity of supporting multiple protocols.
Solution Approach 2:
The device uses feedback from the vehicle's identification data to dynamically select and configure the appropriate communication protocol. The system continuously adapts its configuration based on the specific vehicle identified, automatically adjusting to the correct protocol without requiring manual intervention from the user.
3Productivity
If vehicle identification data is used to retrieve configuration data from a server, then communication efficiency and data retrieval capability are improved, but additional data transfer steps and system complexity are introduced
Solution Approach 1:
The system performs preliminary data retrieval by obtaining identification data from the vehicle first, then using this identification data to automatically retrieve the appropriate configuration data from a server before actual diagnostic operations begin. This pre-configuration approach streamlines the overall process despite adding an initial data transfer step.

AI summary
In a method for operating a device for requesting diagnostic data of a vehicle and a communication device identification data is requested from the vehicle by the device. In response to receiving the identification data from the vehicle, the identification data is sent to a communication device. In response to receiving the identification data by the communication device configuration data for a vehicle or manufacture specific communication is requested from a configuration server depending on the identification data by the communication device. In response to receiving the configuration data by the communication device, the configuration data is sent to the device. In response to receiving the configuration data by the device, the configuration data is stored in the device for requesting diagnostic data of the vehicle by use of the configuration data for the vehicle or manufacture specific communication.
