Innovation Solution
A system utilizing artificial intelligence, including machine learning and natural language processing, that integrates vehicle-based and cloud-based data sources to provide vocal, visual, and tactile interactions, proactive notifications, and charge authorization, allowing for user-directed and vehicle-directed interactions, cognitive load management, and personalized experiences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system integrates multiple data sources and AI processing capabilities to provide proactive assistance, then the assistant's responsiveness and personalization improve, but the system complexity increases
Solution Approach 1:
The system is divided into distinct functional modules: data collection module that gathers information from multiple sources, AI processing module that analyzes the data, cognitive load assessment module that evaluates user state, and interaction module that delivers personalized assistance. This segmentation allows each component to be optimized independently while maintaining overall system adaptability.
Solution Approach 2:
The system performs preliminary actions by continuously collecting and pre-processing data from multiple sources in the background, assessing cognitive load proactively, and preparing personalized responses before users explicitly request them. This enables the assistant to provide timely, relevant assistance without waiting for user initiation, thereby improving responsiveness without proportionally increasing perceived complexity.
2Reliability
If the system provides comprehensive notifications and information to users, then user awareness and safety improve, but cognitive load on the user increases
Solution Approach 1:
The notification system dynamically adjusts its behavior based on real-time cognitive load assessment. When cognitive load is high, the system reduces notification frequency and prioritizes only critical safety information. When cognitive load is low, the system can provide more comprehensive information and proactive assistance. This dynamic adaptation maintains user safety while preventing cognitive overload.
Solution Approach 2:
The system continuously monitors user responses and cognitive load indicators, using this feedback to adjust notification strategies. If users appear overwhelmed or do not respond to notifications, the system learns to modify its communication approach, reducing harmful cognitive load while maintaining essential safety communications.
3Ease of operation
If the system processes and responds to user commands in real-time, then user convenience improves, but processing time and computational resources increase
Solution Approach 1:
The system performs preliminary data processing and pattern recognition in the background before user commands are fully processed. By pre-analyzing data streams and preparing potential responses, the system can provide real-time user convenience without incurring full processing costs for every interaction, thereby reducing effective processing time.
Solution Approach 2:
The system dynamically changes processing parameters based on command priority and context. High-priority commands receive full computational resources for immediate processing, while lower-priority commands are queued or processed with reduced resource allocation. This parameter adjustment maintains user convenience for critical operations while managing overall processing time and computational load.
Data Source
AI summary
The present disclosure relates to an automotive virtual personal assistant configured to provide intelligent support to a user, mindful of the user environment both in and out of a vehicle. Further, the automotive virtual personal assistant is configured to contextualize user-specific vehicle-based and cloud-based data to intimately interact with the user and predict future user actions. Vehicle-based data may include spoken natural language, visible and infrared camera video, as well as on-board sensors of the type commonly found in vehicles. Cloud-based data may include web searchable content and connectivity to personal user accounts, fully integrated to provide an attentive and predictive user experience. In contextualizing and communicating these data, the automotive virtual personal assistant provides improved safety and an enhanced user experience.
