Vehicle Presentation Control for Anticipating Large Behavior Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles controlled by a vehicle control device, occupants experience anxiety due to the difficulty in anticipating large behavior changes, such as lane changes, as the information presentation does not effectively convey the magnitude of upcoming changes, leading to uncertainty and anxiety.
Innovation Solution
A presentation control device that acquires a travel plan indicating the vehicle's control actions and determines if the control target values for acceleration/deceleration or steering are beyond a threshold, allowing for advanced presentation of the vehicle's control actions via an information presentation device, enabling occupants to anticipate large behavior changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle control device controls the behavior of the vehicle as gently as possible, then the comfort of the occupant is improved, but the occupant cannot recognize in advance the occurrence of a scheduled large behavior change, leading to anxiety
Solution Approach 1:
The system performs preliminary action by presenting information about scheduled behavior changes in advance to the occupant. The presentation execution section displays the scheduled behavior change information before the actual behavior change occurs, allowing the occupant to anticipate and mentally prepare for the upcoming change, thereby reducing anxiety while maintaining gentle vehicle control
2Measurement precision
If information presentation follows the actual behavior change of the vehicle, then the information is accurate, but the change per unit time is too small for the occupant to image the magnitude of the behavior change
Solution Approach 1:
The system displays scheduled behavior change information in advance, showing the magnitude and nature of upcoming changes before they occur. This preliminary presentation allows the occupant to understand the full extent of the scheduled change, making the information both accurate and comprehensible
Solution Approach 2:
The system dynamically adjusts the information presentation based on the characteristics of the scheduled behavior change. By presenting information about future changes with appropriate timing and magnitude representation, the system makes the subtle changes perceivable and understandable to the occupant

AI summary
A presentation control device controlling an information presentation device in a vehicle equipped with a vehicle control device for controlling an acceleration-deceleration function or a steering function, includes: a plan acquisition section that acquires a travel plan indicating a control content of the vehicle; a behavior change determination section that determines whether a control target value relating to a magnitude of a behavior change included in the travel plan is larger than an advance threshold; and a presentation execution section that presents the control content to the occupant using the information presentation device in accordance with the behavior change occurring in the vehicle when the control target value is smaller than the advance threshold, and presents the control content temporarily in advance of an actual behavior change when the control target value is larger than the advance threshold.
