Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle testing and diagnosis processes are inefficient, lacking a unified solution for seamless communication and data transfer between vehicle components, developers, and server systems, which hinders effective access, analysis, and management of vehicle data.
Innovation Solution
A processing unit with multiple communication interfaces for wireless data transfer (e.g., Bluetooth, WLAN, NFC, 3G/4G/5G) that enables keyless vehicle access, receives and processes vehicle entry and analysis data, and transfers provision data to servers or mobile devices, allowing developers to access and update vehicle functions remotely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional vehicle testing and diagnosis processes are used, then vehicle functions can be tested, but the processes are inefficient and lack unified communication between vehicle components, developers, and server systems
Solution Approach 1:
The system is segmented into three distinct communication interfaces: a first interface for wireless communication between the processing unit and server apparatus, a second interface for wireless communication with mobile apparatus, and a third interface for communication with the vehicle bus network. This segmentation allows each interface to handle specific communication tasks independently, improving testing efficiency while managing complexity through modular architecture
Solution Approach 2:
The processing unit is designed with multi-functional capability to perform both vehicle testing and diagnosis operations through a unified platform. It can receive vehicle entry data for access authorization, process vehicle analysis data from the bus network, and transfer provision data to servers or mobile devices, consolidating multiple functions into a single processing unit
2Ease of operation
If developers need to access vehicle data for testing and diagnosis, then vehicle analysis can be performed, but current processes lack seamless communication and data transfer capabilities
Solution Approach 1:
The processing unit acts as an intermediary device between the vehicle bus network, mobile apparatus, and server apparatus. It receives vehicle analysis data from the bus network, processes it, and transfers provision data to external systems through wireless interfaces, ensuring reliable data transfer while enabling easy developer access to vehicle information
Solution Approach 2:
The processing unit pre-processes vehicle analysis data received from the bus network before transfer, converting it into provision data format suitable for external systems. This preliminary processing ensures data integrity and reduces transfer complexity, enabling seamless communication without information loss
3Adaptability or versatility
If keyless access and remote data transfer are implemented, then vehicle access and updates are simplified, but communication infrastructure complexity increases
Solution Approach 1:
The processing unit implements universal communication capability through multiple wireless interfaces that can handle both keyless access authentication and remote data transfer operations. The first interface communicates with server apparatus for remote updates, the second interface handles mobile apparatus for keyless access, demonstrating multi-functional adaptability
Solution Approach 2:
Communication functions are segmented into distinct interfaces: the first interface for server communication, the second for mobile device communication, and the third for vehicle bus network communication. This segmentation provides access flexibility while managing complexity through specialized dedicated channels for each communication type

AI summary
A processing unit includes a first communication interface that is designed for communication with a server device and/or a mobile device. The processing unit also has a second communication interface, which is designed for communication with the mobile device. The processing unit further has an internal communication interface of the processing unit, which is designed for communication with a vehicle bus network of the vehicle. The processing unit is designed to receive vehicle access data, which is representative of an access authorization of a driver to the vehicle via the second communication interface. The processing unit is also designed to determine depending on the vehicle access data a release signal for enabling a use of the vehicle and to provide it to the internal communication interface. The processing unit is also designed to receive vehicle analysis data via the internal communication interface.
