Vehicle Message Display Adaptation for Driver Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle information systems fail to provide critical messages to drivers without interfering with safe operation of the vehicle, particularly when the vehicle is in motion, as unconditional output of messages can distract the driver and compromise safety.
Innovation Solution
An information processing apparatus and method that adjusts the display size and content of messages based on the vehicle's traveling state, outputting messages in a reduced second display mode while driving to minimize distraction and ensuring essential travel information remains accessible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If messages are output on a full display area, then information visibility is improved, but driver distraction increases when the vehicle is traveling
Solution Approach 1:
The display area size is dynamically adjusted based on the vehicle's traveling state. When the vehicle is detected to be traveling, the display area for messages is reduced to minimize driver distraction. When the vehicle is stationary, the display area is expanded to improve message visibility. This dynamic adaptation resolves the contradiction by making the display system flexible rather than fixed.
Solution Approach 2:
The patent changes the display parameter (display area size) based on the vehicle's operational state. By detecting whether the vehicle is traveling or stationary and adjusting the display area accordingly, the system optimizes both information visibility and driver safety. This parameter change approach allows the same display system to serve different functions under different conditions.
2Reliability
If message display size is reduced during travel, then driver safety is improved, but information completeness deteriorates
Solution Approach 1:
The system periodically monitors the vehicle's traveling state and adjusts the display area accordingly. During travel, the reduced display area maintains essential safety information while minimizing distraction. When the vehicle stops, the display area expands to provide complete message information. This periodic adjustment based on state changes ensures both safety during motion and information completeness during stationary periods.
Solution Approach 2:
The display system transitions between different display modes (reduced size during travel, full size when stationary) based on real-time detection of vehicle state. This dynamic switching ensures that the appropriate level of information display is provided for each operational context, resolving the contradiction between safety and information completeness.

AI summary
An information processing apparatus for providing information for a driver of a vehicle, the information processing apparatus comprises a controller configured to execute: receiving message data that includes a message to the driver of the vehicle; when receiving the message data, outputting the message on a display area provided on a screen; and changing a size of the display area where the message is outputted, based on whether the vehicle is traveling or not.
