In-Vehicle Voice Command Routing for Low-Load System Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-vehicle computing systems face limitations in supporting complex voice control due to the utilization of majority processing and memory resources for basic functionalities, making it difficult to effectively control vehicle components through voice commands.
Innovation Solution
Leveraging the processing and memory resources of a mobile device positioned within the vehicle to provide sophisticated voice control by routing vocal commands to either the in-vehicle virtual personal assistant or a mobile device's virtual personal assistant, allowing for advanced control of vehicle systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the in-vehicle computing system uses its own processing resources for voice control, then voice control functionality is integrated, but the system cannot support complex voice control due to limited processing and memory resources
Solution Approach 1:
The patent introduces a mobile device as an intermediary component that bridges the in-vehicle computing system and voice control processing. The mobile device receives voice commands from the in-vehicle system, processes them using its own computing resources, and returns control signals to actuate vehicle components. This intermediary approach allows complex voice control functionality without overloading the in-vehicle computing system's limited resources.
2Adaptability or versatility
If the in-vehicle computing system allocates more resources to voice control, then voice control sophistication improves, but basic functionality performance deteriorates
Solution Approach 1:
The patent segments the voice control processing function from the in-vehicle computing system and relocates it to a mobile device. This segmentation allows the in-vehicle system to maintain its basic functionalities with dedicated resources while the mobile device handles sophisticated voice control processing independently, preventing resource contention and performance degradation.
3Ease of operation
If the system integrates all control functions in one system, then control integration is achieved, but the system becomes overly complex for user operation
Solution Approach 1:
The patent replaces the traditional mechanical/control interface complexity with a voice-based acoustic interface. Instead of requiring users to navigate complex menus or operate multiple controls, the system accepts natural voice commands that are processed by the mobile device and translated into appropriate control actions, significantly simplifying user interaction despite the underlying system complexity.
