Vehicle Object Overlay for Automatic Driving Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle display systems for automatic driving lack clarity in conveying the future behavior of the vehicle, making it difficult for drivers to understand the vehicle's position and planned actions, and fail to provide notifications for high automatic braking states when not predicted.
Innovation Solution
A display control apparatus that acquires a vehicle's travel control plan and predicts its future position, overlaying a vehicle object on a landscape to visually represent the vehicle's future movement, enhancing the driver's understanding of the vehicle's planned actions and providing timely notifications for high automatic braking states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simplified notification method is used to convey vehicle behavior, then the device complexity is reduced, but the clarity and concreteness of the information provided to the driver deteriorates
Solution Approach 1:
The patent creates a virtual copy of the vehicle (virtual vehicle marker) that mirrors the actual vehicle's future position and behavior. This virtual representation is displayed on the HUD to convey detailed information about the vehicle's planned actions without requiring complex physical notification devices. The virtual vehicle marker includes visual elements that represent the vehicle's future position, orientation, and intended maneuvers, providing concrete spatial information to the driver.
Solution Approach 2:
The patent transitions from conventional 2D display notifications to a 3D spatial representation by projecting the virtual vehicle marker onto the HUD at the appropriate spatial location corresponding to the vehicle's future position. This dimensional enhancement allows the driver to perceive the vehicle's future behavior in the context of the actual driving environment, providing more intuitive and concrete spatial awareness.
2Reliability
If the notification system only activates under predicted conditions, then the false alarm rate is reduced, but the timeliness of notifications for unexpected high-risk situations deteriorates
Solution Approach 1:
The notification system dynamically adjusts its activation criteria based on the automatic braking state. When a high automatic braking state is detected, the system immediately activates the virtual vehicle marker notification regardless of whether the condition was predicted, ensuring timely awareness. The system continuously monitors braking states and adapts its notification behavior in real-time, balancing reliability with responsiveness to unexpected situations.
3Loss of information
If detailed information about future vehicle behavior is provided, then the driver's understanding improves, but the information processing load on the driver increases
Solution Approach 1:
The patent segments the information about future vehicle behavior into distinct visual elements within the virtual vehicle marker. The marker is divided into components that represent different aspects such as future position, orientation, and intended maneuvers. This segmentation allows the driver to process information in manageable units rather than receiving a single complex data stream, reducing cognitive load while maintaining information completeness.

AI summary
A display control apparatus controls a display used in a vehicle which can travel with automatic driving. The display control apparatus includes an information acquirer and a controller. The information acquirer acquires information of a travel control plan generated by an automatic driving control device of the vehicle. The controller acquires a future position which is a position of the vehicle after an elapse of a predetermined time from a current position of the vehicle from a future movement of the vehicle planned by the travel control plan, and controls the display so that a user is visually provided with the future position of the vehicle by overlapping a vehicle object which is a display object imitating a vehicle shape with a landscape relating to the future position which is acquired.
