Cabin Acceleration Display Layout for Intuitive Vehicle Motion Cues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems require attention to the driver seat area to understand vehicle movements, which can be inconvenient and may lead to confusion or motion sickness during acceleration or turns.
Innovation Solution
A vehicle display control device that predicts acceleration directions based on planned travel paths, periphery information, and acceleration sensor data, and displays these directions at various cabin locations using light patterns, colors, and arrows to intuitively inform occupants without needing to focus on the driver seat.

Engineering Contradiction Analysis
1Loss of information
If acceleration direction is displayed at the driver seat area using existing systems, then vehicle movement information is provided to the driver, but the driver must pay attention to the driver seat area which causes inconvenience and may lead to confusion or motion sickness
Solution Approach 1:
The patent projects acceleration direction information from the traditional driver seat area onto multiple surfaces in the vehicle cabin including the windshield, side windows, and interior trim members. This spatial redistribution of display locations allows drivers to perceive vehicle movement information in their peripheral vision without needing to focus on the instrument panel area, thereby reducing cognitive load and preventing motion sickness while maintaining information delivery.
2Ease of operation
If acceleration direction is displayed at multiple display portions in the vehicle cabin, then intuitive understanding of vehicle movements is achieved without attention to driver seat, but the device complexity increases
Solution Approach 1:
The patent employs projection technology that can be integrated into existing vehicle display systems, using the same projection mechanism to display acceleration direction information across multiple surfaces (windshield, side windows, interior trim). This multi-functional approach allows a single projection system to serve multiple display locations simultaneously, reducing the need for separate display devices at each location and thereby limiting the increase in device complexity while achieving intuitive understanding throughout the cabin.

AI summary
A vehicle display control device (10,70,80) includes: an acceleration prediction section (64) that predicts a direction of an acceleration acting on a vehicle (12,72,82) based on information including at least one of: information regarding a planned travel path of the vehicle (12,72,82), information acquired from a periphery information detection sensor (56) that detects information regarding a vehicle periphery, or information acquired from an acceleration sensor (54) that detects an acceleration of the vehicle (12,72,82); and a display control section (66) that, in a case in which an acceleration predicted by the acceleration prediction section is greater than a predetermined threshold, displays a direction of the predicted acceleration at a display portion in a vehicle cabin.
