Vehicle Display Control for Adaptive Driving Information Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-level automated driving scenarios where a driver is not required to monitor the surroundings, existing systems reduce travel-related information displayed to the driver, leading to decreased convenience due to insufficient information during non-monitoring-obligation automated driving.
Innovation Solution
A vehicle display control device and method that identifies the vehicle's situation to selectively reduce travel-related information on the dashboard, ensuring that essential information is maintained even during non-monitoring-obligation automated driving, thereby enhancing driver convenience.

If travel-related information is reduced during non-monitoring-obligation automated driving, then the automated driving function is improved, but driver convenience deteriorates
Solution Approach 1:
The display control device dynamically adjusts the amount of travel-related information displayed based on the identified vehicle situation. During non-monitoring-obligation automated driving, the system reduces information display when the vehicle is in a stable state (e.g., cruising on highway), but suppresses this reduction when the vehicle enters situations requiring driver awareness (e.g., approaching intersections, adverse weather). This dynamic adjustment resolves the contradiction by making the automation adaptive to contextual needs.
Solution Approach 2:
The system changes the parameter of information display quantity based on vehicle situation parameters. When the vehicle situation indicates stable automated driving conditions, the information display parameter is reduced. When situation parameters indicate potential risks or complex environments, the display parameter is increased to maintain driver convenience and awareness, thus resolving the contradiction between automation and ease of operation.

AI summary
Disclosed is a technique of controlling display of travel related information on an indicator provided in a vehicle that can be switched between non-monitoring-obligation automated driving and monitoring-obligation driving. The non-monitoring-obligation automated driving is automated driving without a surrounding monitoring obligation. The monitoring-obligation driving is driving with the surrounding monitoring obligation. In the method, the travel related information displayed during the non-monitoring-obligation automated driving is reduced compared to the travel related information displayed during the monitoring-obligation driving. Reduction of the travel related information is suppressed based on an identified vehicle situation during the non-monitoring-obligation automated driving.
