Vehicle Information Processing Device Answer Display Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle information processing systems cannot display answers to occupant questions at appropriate times during vehicle travel, as they only provide voice synthesis and do not consider displaying information when the vehicle is in motion.
Innovation Solution
An information processing device that acquires question information and vehicle state information, stores answer information including images when the vehicle is traveling, and outputs it when the vehicle is stopped, allowing for timely display of answers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the system displays answer information on a monitor during vehicle travel, then the occupant can confirm the answer visually, but display restriction prevents this during traveling
Solution Approach 1:
The system performs preliminary actions by acquiring and storing answer information in advance when the vehicle is traveling, before the actual display is needed. This allows the information to be ready for immediate display once the vehicle stops, eliminating the loss of information while avoiding display restrictions during travel.
Solution Approach 2:
The system dynamically adjusts its operation based on vehicle state (traveling vs. stopped). During traveling, it performs data acquisition and storage operations; when stopped, it switches to display operations. This dynamic adaptation resolves the contradiction by allowing information processing at appropriate times based on vehicle conditions.
2Loss of information
If the system provides only voice synthesis output, then the system is simple, but the occupant cannot visually confirm the answer
Solution Approach 1:
The system prepares answer information in advance by acquiring and storing it during vehicle travel, so that when the vehicle stops, the information is already ready for display. This preliminary preparation eliminates the need for complex real-time processing during stop conditions, reducing overall system complexity while enabling visual confirmation.
3Reliability
If the system stores answer information during traveling, then the information is ready for display when stopped, but requires additional storage processing
Solution Approach 1:
The system performs the action of acquiring and storing answer information in advance during vehicle travel, before the display is actually needed. This preliminary preparation ensures reliable information delivery when the vehicle stops, while the storage mechanism itself remains relatively simple (temporary storage in memory), balancing reliability with acceptable complexity.

AI summary
An information processing device acquires question information. The information processing device acquires vehicle state information representing a state of the vehicle. The information processing device acquires answer information in response to the question information, the answer information including an image for display. The information processing device, in a case in which the vehicle state information represents that the vehicle is traveling, stores the answer information in a storage. The information processing device, in a case in which the information processing device acquires vehicle state information representing that the vehicle is stopped, outputs the answer information stored in the storage.
