Vehicle Display Device for Occluded Object Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face challenges in detecting hidden objects around vehicles, such as preceding vehicles, pedestrians, and road structures, which can lead to accidents due to obstructed visibility, especially at high speeds.
Innovation Solution
A display apparatus for vehicles that includes a processor and display unit to show graphic objects corresponding to hidden objects, using information from external sensors to project augmented reality images on the windshield, ensuring the driver's awareness of potential hazards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver relies on direct visual observation, then the driver can see clearly visible objects, but hidden objects obstructed by terrain or other vehicles cannot be detected
Solution Approach 1:
The patent introduces a display unit as an intermediary between the hidden object and the driver's visual system. Sensors detect hidden objects, and the display unit presents this information in the driver's field of view, mediating the detection process to overcome physical obstructions without requiring the driver to leave their position or change the vehicle's structure significantly
Solution Approach 2:
The system creates a visual copy or representation of hidden objects through graphic objects displayed on the display unit. Instead of requiring direct observation of the actual hidden object, the system generates a replicated visual indicator that conveys the presence, position, and nature of the hidden object, allowing the driver to perceive information that would otherwise be inaccessible
2Loss of information
If graphic objects are displayed to show hidden objects, then driver awareness of hidden objects is improved, but the system complexity increases due to sensors and processing units
Solution Approach 1:
The display unit serves multiple functions: it displays hidden objects, provides navigation information, and can show various types of alerts and warnings. By making the display unit multi-functional, the patent reduces the need for separate dedicated systems for each function, thereby managing complexity while maintaining comprehensive information provision
Solution Approach 2:
The system integrates sensor data processing and graphic object generation within the same control architecture that manages the display unit. The processor that controls the display also processes sensor information and generates appropriate visual representations, allowing the system to serve itself rather than requiring separate dedicated components for each processing stage
3Measurement precision
If multiple sensors and electronic devices are provided for object detection, then the detection capability is improved, but the device complexity and cost increase
Solution Approach 1:
The system dynamically adjusts which sensors are active and how their data is processed based on driving conditions, vehicle speed, and detected object types. This dynamic operation allows the system to achieve high detection precision when needed while reducing complexity during normal driving conditions, optimizing the balance between performance and simplicity

AI summary
Disclosed is a display apparatus for vehicle comprising: a display unit; an interface unit; and a processor configured to receive information on a first object and a second object positioned outside a vehicle through the interface unit, and control the display unit to display a graphic object corresponding to the first object, when the second object is positioned between the vehicle and the first object.
