Solution Overview
Problem
Current vehicles lack a comprehensive ecosystem that integrates physical and mental comforts, failing to create a seamless and intuitive user experience by not fully considering the vehicle as an environment that operates seamlessly with electronic devices.
Innovation Solution
A vehicle ecosystem that combines physical and mental comfort features with electronic devices, using a communication system to create a universal bus and hotspot, allowing applications, data, and multimedia information to be shared between the vehicle and other devices, with operating systems managing critical vehicle tasks and infotainment functions independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operating systems are integrated to manage both critical vehicle tasks and infotainment functions, then system functionality and user experience are improved, but system complexity increases
Solution Approach 1:
The patent divides the vehicle's computing system into multiple independent operating systems: a first operating system dedicated to critical vehicle tasks (safety, control, monitoring) and a second operating system dedicated to infotainment functions (media, navigation, communication). This segmentation allows each OS to be optimized for its specific purpose while reducing interference between critical and non-critical functions, thereby managing complexity through functional separation.
Solution Approach 2:
The patent creates a unified vehicle ecosystem where multiple operating systems and electronic devices can coexist and communicate through a common framework. The system provides universal interfaces and protocols that allow diverse devices (mobile phones, tablets, wearables) to integrate with the vehicle's infotainment and control systems, enabling multi-functionality without proportionally increasing complexity.
2Ease of operation
If a comprehensive vehicle ecosystem integrating multiple devices and systems is created, then user comfort and convenience are improved, but device complexity increases
Solution Approach 1:
The patent introduces intermediary components including a communication system with a universal bus and hotspot that mediate between multiple electronic devices and the vehicle's control systems. These intermediaries provide standardized interfaces and protocols, allowing devices to communicate seamlessly without requiring complex direct integrations between each device pair, thus simplifying the overall system architecture while enabling comprehensive device integration.
Solution Approach 2:
The patent implements a nested architecture where the vehicle ecosystem contains multiple layers of integration: the vehicle platform nests infotainment systems, which in turn nest mobile device connections and applications. This hierarchical nesting allows complex functionality to be organized in manageable layers, where each layer operates semi-independently but contributes to the overall integrated experience, reducing perceived complexity for users.
3Ease of manufacture
If operating systems share a common microprocessor to reduce hardware complexity, then manufacturing cost is reduced, but system reliability may be affected
Solution Approach 1:
The patent assigns different operating systems to execute on a common microprocessor but implements logical segmentation through virtualization or time-sliced execution. Critical vehicle tasks are isolated from infotainment operations through separate execution environments, ensuring that failures in the infotainment system do not compromise critical functions. This maintains hardware simplicity while preserving reliability through software-level isolation.
Solution Approach 2:
The patent implements protective measures by designing the multi-operating system architecture to prevent cascading failures. The system includes isolation mechanisms and error containment protocols that cushion against potential reliability issues, ensuring that problems in one operating system or application do not propagate to other critical systems, thereby maintaining overall system reliability despite shared hardware resources.
Data Source
AI summary
A vehicle communication system and method for allowing a user device to stream content to a vehicle display is provided. The communication system receives a request from the user device, approves or denies a user request to connect to the vehicle display, and facilitates streaming of an application running on the user device to the vehicle display.
