Solution Overview
Problem
Current communication devices for motor vehicles do not effectively extend their functional range to provide real-time operating data to drivers during autonomous drive modes, limiting driver information and control integration with mobile apparatuses.
Innovation Solution
A communication device and method that transmit operating data from motor vehicle components to a mobile apparatus within the vehicle, allowing data display only during autonomous drive modes, with adaptive display areas and modes for enhanced driver information and control, using an interface device connected to navigation, cameras, and drive control units, enabling real-time video and navigation data presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If operating data is continuously displayed on the mobile apparatus during both manual and autonomous drive modes, then driver information availability is improved, but driver distraction and safety risks increase during manual driving
Solution Approach 1:
The mobile apparatus dynamically switches between a first operating mode (during autonomous driving) and a second operating mode (during manual driving). The interface device detects the drive mode and automatically adjusts the display behavior, enabling operating data visualization only when the vehicle is in autonomous drive mode, thereby eliminating driver distraction while maintaining information availability when needed
2Loss of information
If the communication device provides real-time operating data transmission to mobile apparatus, then driver awareness during autonomous driving is improved, but system complexity increases
Solution Approach 1:
The interface device serves multiple functions: it detects the drive mode (manual or autonomous), manages the communication connection between the mobile apparatus and vehicle systems, controls the operating mode switching of the mobile apparatus, and regulates data transmission. This multi-functionality reduces the need for separate dedicated components, thereby managing system complexity while enabling real-time operating data transmission
3Object-affected harmful factors
If the mobile apparatus is restricted to second operating mode during manual driving, then driver safety is improved, but functional versatility of the communication device is reduced
Solution Approach 1:
The system periodically transitions between operating modes based on the drive mode. During manual driving, the mobile apparatus operates in the second mode (restricted functionality). When autonomous driving is activated, it switches to the first mode (full functionality with operating data display). This periodic switching ensures driver safety during manual operation while maximizing functional versatility during autonomous operation
