Graphical Gauge Hosting Mobile Apps for Vehicle HMI
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Human Machine Interfaces (HMIs) in vehicles require significant development and licensing costs for custom navigation and GPS systems, limiting their competitiveness due to lower production volumes and inability to share display resources with mobile platforms like Android and iOS.
Innovation Solution
A graphical instrument or gauge that hosts applications from a mobile application platform, allowing mixed graphical information from native and guest systems to be displayed on a single interface, with a transparency layer enabling coexistence and user interaction without requiring re-invention of mobile applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a native operating system is used to support custom navigation and GPS systems, then the system can be fully customized to meet end customer needs, but significant development time, debugging effort, and licensing fees are required
Solution Approach 1:
The HMI construction is designed to support multiple operating systems (native OS and mobile platforms like Android and iOS) simultaneously, allowing the same hardware platform to serve both custom vehicle-specific applications and general-purpose mobile applications without requiring separate development efforts
Solution Approach 2:
A dual-OS architecture is introduced as an intermediary layer that enables communication and resource sharing between the native operating system and mobile application platforms, allowing navigation and GPS functionality to be accessed through familiar mobile applications while maintaining integration with vehicle systems
2Adaptability or versatility
If mobile application platforms are integrated into the HMI, then familiar mobile applications can be displayed, but display resources and user feedback resources cannot be shared with the native operating system
Solution Approach 1:
The display resources and user feedback resources of the mobile application platform are merged with those of the native operating system at the hardware level, allowing both systems to simultaneously access the same display, touchscreen, and audio resources without requiring duplicate components
Solution Approach 2:
The system transitions from a single-OS architecture to a multi-OS architecture, adding a new dimension of operational capability that allows mobile applications and native applications to coexist and share resources through a unified resource management layer
3Adaptability or versatility
If custom graphical gauges are developed to meet end customer needs, then vehicle status information can be fully customized, but the system requires significant development effort and cannot leverage existing mobile applications
Solution Approach 1:
The HMI platform is designed to universally support both custom native applications and standard mobile applications, eliminating the need to reinvent mobile applications for each vehicle platform while maintaining the ability to display custom vehicle status information through integrated graphical gauges
Data Source
AI summary
An interface panel or graphical gauge that can host applications from a mobile application platform and display content from the hosted applications on a display of the graphical gauge. The interface panel may include a native operating system supporting an interface application that generates interface graphical output fed by the native operating system to a graphics controller. The interface control system may be configured to support a guest system that generates guest graphical output fed to the graphics controller. The guest graphical output is representative of graphic information generated by the mobile application platform.
