Vehicle Exterior Display for Automated Driving Difficulty Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated driving technologies do not effectively utilize information about the difficulty level of automated traveling control, limiting its usefulness for drivers and external observers.
Innovation Solution
A display control device that acquires the difficulty level of automated traveling control and causes a display device to visually convey this information to external observers, using sensors and vehicle-to-vehicle communication to determine and display the level, enabling informed actions by nearby drivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If attention calling notification is made to the driver based on automated driving difficulty level, then driver awareness is improved, but the driver becomes accustomed to the notification and its effectiveness decreases
Solution Approach 1:
The notification system dynamically changes its behavior based on the driver's response patterns. When the driver pays attention to notifications, the system varies the notification methods (visual, auditory, haptic) and timing to prevent habituation. The notification strategy adapts in real-time to maintain effectiveness.
Solution Approach 2:
The system monitors driver responses to notifications and uses this feedback to adjust future notification strategies. By detecting whether the driver is paying attention or becoming accustomed, the system modifies notification intensity, frequency, and modality to maintain optimal alertness without causing habituation.
2Adaptability or versatility
If difficulty level information is only presented to the driver, then driver information needs are met, but external observers cannot understand the automated driving state
Solution Approach 1:
The notification system serves multiple functions simultaneously: it informs the driver of automated driving difficulty levels while also providing this information to external observers through vehicle exterior displays. This multi-functional approach ensures both driver awareness and external communication without requiring separate systems.
Solution Approach 2:
The vehicle exterior display acts as an intermediary that translates internal automated driving state information into externally visible indicators. This mediator communicates the difficulty level to pedestrians, cyclists, and other road users, enabling them to understand the vehicle's automated driving state and adjust their behavior accordingly.
3Reliability
If automated driving information is displayed externally, then external observer understanding is improved, but device complexity increases
Solution Approach 1:
The system merges the interior driver display and exterior observer display into a unified notification system. Both displays share the same information source and control logic, allowing the difficulty level information to be simultaneously presented to drivers and external observers without requiring completely separate hardware and software systems.

Described is a display control device that acquires a difficulty level of an automated traveling control of a mobile object. A display device for visual recognition by a person outside the mobile object whose difficulty level has been acquired is caused to perform display according to the acquired difficulty level.
