Vehicle Communication System with Hands-Free Audio Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems in vehicles lack seamless integration of vehicle data and network data management, particularly in providing hands-free and immersive communication experiences for drivers, with limited ability to convert and prioritize information in real-time.
Innovation Solution
A vehicle communication system with a control unit connected to a vehicle data bus and a mobile communication device, enabling the conversion of vehicle and network data into audible speech, and offering features like hands-free email, enhanced caller ID, and unified information management through text-to-speech technology and voice commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mobile communication device processes and displays all network data in self-contained mode, then the device maintains operational independence, but the driver cannot receive hands-free communication assistance while driving
Solution Approach 1:
The patent merges the mobile communication device with the vehicle's existing hands-free communication system. The mobile device integrates with the vehicle's microphone, speaker, and audio processing capabilities, allowing the driver to receive calls, messages, and notifications hands-free through the vehicle's audio system rather than holding or looking at the mobile device.
Solution Approach 2:
The system provides multi-functionality by combining mobile communication capabilities with vehicle audio system capabilities. The integrated system can handle voice calls, text messages, email notifications, and vehicle information display through a unified interface that leverages both the mobile device's connectivity and the vehicle's audio output.
2Loss of information
If the system converts all vehicle data and network data to audible speech, then the driver receives comprehensive information, but the driver becomes overwhelmed by information overload
Solution Approach 1:
The system applies local quality by providing different types of information through different channels based on their importance and nature. Critical safety-related vehicle data is presented through visual displays on the dashboard, while non-critical communication information (emails, messages) is converted to audible speech. The system selectively routes information based on its priority and type.
Solution Approach 2:
The system uses partial action by converting only selected network data to audible speech rather than all data. It prioritizes converting email content and non-urgent communications to speech while leaving visual display for more complex information. The system also allows the driver to selectively enable or disable speech conversion for different types of information.
3Adaptability or versatility
If the system integrates multiple data sources and conversion capabilities, then the communication experience becomes more immersive, but the processing time and system complexity increase
Solution Approach 1:
The system performs preliminary action by pre-processing and categorizing incoming data as it arrives from various sources. Email messages are pre-analyzed to determine their importance and suitability for speech conversion. The system pre-loads translation dictionaries and speech synthesis templates, so when the driver requests information conversion, the processing time is minimized because the groundwork has already been done.
Data Source
AI summary
A vehicle communication system includes a control unit in a vehicle, a vehicle data bus operable to transmit vehicle data to the control unit, and a mobile communication device having data network access. The mobile device has a self-contained mode in which the mobile communication device processes and displays the network data received via the data network and in which the control unit transmits the vehicle data to the mobile communication device. The mobile communication device also has an immersive mode in which the control unit processes the network data received via the data network and in which the control unit converts the vehicle data to audible speech and plays the audible speech in the vehicle.
