Vehicle Agent Intent Inference Using State-Aware Question Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle agent processing devices, such as those described in JP-A No. 2001-141500, face limitations in inferring the intent of user questions with sufficient precision when searching an owner's manual, particularly in understanding the context provided by the vehicle's state information.
Innovation Solution
An agent device and system that includes a processor configured to receive state information from a vehicle and user questions, perform inference processing using trained models generated from past vehicle states and expressions, and acquire responses based on inferred intent, enhancing inference precision by considering the vehicle's state and utilizing vehicle control communication information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the vehicle agent processing device uses basic question processing without considering vehicle state information, then the device complexity is reduced, but the intent inference precision deteriorates
Solution Approach 1:
The patent combines question information from the user with state information from the vehicle into a unified processing framework. The processor integrates both types of information simultaneously, merging them into a combined input for the inference processing, thereby improving intent inference precision while managing complexity through unified handling
Solution Approach 2:
The processor is designed to handle multiple types of input (question information and state information) through a single inference processing mechanism. This multi-functional approach allows the same processing unit to analyze both user queries and vehicle state data, improving inference accuracy without proportionally increasing device complexity
2Reliability
If the agent device processes only question information without state information, then the processing speed is maintained, but the response accuracy to contextual questions deteriorates
Solution Approach 1:
The system performs preliminary acquisition of state information from the vehicle before processing the user's question. By having the state information readily available and pre-processed, the system can quickly integrate it with the question during inference processing, improving response accuracy without significant time loss
Solution Approach 2:
The inference processing continuously utilizes both question information and state information in an integrated manner. The processor maintains continuous access to both data streams and processes them together throughout the inquiry handling, ensuring consistent response accuracy while maintaining efficient processing flow

AI summary
An agent device that receives state information regarding a state of a vehicle from the vehicle, and receive a question from a user as question information; performs inference processing for the received question information and the received state information in order to infer an intent of the question; and acquires a response to the question based on the inferred intent.
