In-Vehicle Presentation Plan Creation for Driver Leeway
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle information systems fail to determine optimal information presentation timing and amount based on future destinations and paths, and do not consider the characteristics of various output devices, leading to inadequate information presentation.
Innovation Solution
A presentation plan creation apparatus that sets paths to destinations, divides them by road type, predicts driving behavior proportions, acquires device leeway data, and creates a presentation plan by selecting suitable output devices and paths based on required leeway and viewing time, ensuring information is presented effectively and safely during travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If information presentation timing is determined only using current state (driving load), then the system is simple to operate, but future information presentation timing cannot be determined in advance
Solution Approach 1:
The system performs preliminary actions by determining the travel path and predicting driving load variations in advance before the actual journey. This allows the information presentation timing to be planned ahead rather than reactively determined during driving, resolving the contradiction between advance timing determination and system simplicity.
Solution Approach 2:
The system dynamically adjusts information presentation timing based on predicted driving load variations along different path sections. By making the timing adaptive to predicted conditions rather than static or purely reactive, the system achieves both advance planning capability and appropriate responsiveness.
2Reliability
If driving leeway is predicted from driver's behavior, then information timing can be optimized, but characteristics of various output devices cannot be considered
Solution Approach 1:
The system applies local quality by determining appropriate information presentation timing for each specific output device (center display, head-up display, speaker) based on their individual characteristics. Each device receives customized timing recommendations suited to its display properties and driver interaction patterns, achieving both reliability and device-specific adaptability.
Solution Approach 2:
The system segments the information presentation strategy by device type, creating separate timing recommendations for different output devices rather than a unified approach. This segmentation allows each device to be optimized independently for its specific characteristics while maintaining overall system coherence.
3Productivity
If a plurality of output devices are used, then information can be presented through multiple channels, but information suitable for characteristics of respective output devices cannot be presented
Solution Approach 1:
The system ensures each output device receives information optimized for its specific characteristics by determining device-appropriate presentation timing. The center display, head-up display, and speaker each receive customized timing recommendations based on their display properties and driver interaction patterns, achieving both multi-device capability and device-specific optimization.

AI summary
The present invention aims to create an information presentation plan suitable for characteristics of output devices in view of driver's driving leeway. A presentation plan creation apparatus of the present invention includes: a driving behavior proportion prediction unit that predicts a driving behavior proportion, for each divided path; a device leeway acquisition unit that acquires device leeway data; a presentation item extraction unit that acquires presentation item data; and a presentation plan creation unit that creates a presentation plan in line with a selection condition. The selection condition is that a time of performing, on the selected path, any of the driving behaviors that allows the leeway of the selected device to be equal to or greater than the required leeway required to present the presentation item is equal to or longer than the required viewing time required to view the presentation item.
