Voice-Guided Route Object Recognition for Vehicle Maneuver Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional driving support systems fail to intuitively and easily allow users to specify positions and routes for vehicle operations like turning or stopping, as they rely solely on touch input without clear positional specification.
Innovation Solution
A travel information processing apparatus that uses voice input to estimate objects and their positional relationships, outputting image or voice data to confirm user intentions and adjust vehicle routes accordingly, incorporating a microphone, voice recognition, object recognition, and route change identification units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If touch input on display is used to specify vehicle operations, then the system can specify position changes of the subject vehicle, but it cannot specify positions not displayed on the display or traveling routes indicating turning or stopping
Solution Approach 1:
The patent introduces voice recognition as an intermediary interface between the user and the vehicle control system. The voice recognition unit captures user speech, the recognition result generation unit processes the voice data to extract intent, and the travel information process unit translates this into specific vehicle operations. This intermediary layer enables users to specify both displayed and non-displayed positions as well as various traveling routes (turning, stopping) without being constrained by display boundaries or touch interface limitations.
2Ease of operation
If voice input is used to specify objects and routes, then the system can intuitively capture user intent, but the user cannot confirm the correctness of the specified object before execution
Solution Approach 1:
The patent implements a feedback mechanism where the recognition result generation unit outputs the recognized voice commands and interpreted intent back to the user through the display or audio output. The travel information process unit then uses this confirmed feedback to execute the vehicle operations. This allows users to verify that their voice input was correctly interpreted before the vehicle actually performs the maneuver, thereby ensuring reliability while maintaining intuitive operation.

AI summary
A travel information processing apparatus includes a voice input device configured to input voice data of a user, an output device configured to specify an object by estimating from the voice data based on a word extracted from the voice data and indicating the object around a traveling route and a word extracted from the voice data and indicating a positional relationship of the object and output image data or voice data indicating a specified object; and a travel information processor configured to change a traveling motion of a subject vehicle based on the specified object.
