Vehicle Driving Assistance Device with Superimposed Front Pattern
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle driving assistance devices do not effectively provide driving assistance by combining the display of the forward view of a vehicle, lacking comprehensive support for the driver in navigating and maintaining safe distances or avoiding obstacles.
Innovation Solution
A vehicle driving assistance device that includes a display unit to superimpose a front pattern shaped like the vehicle's front on the forward view image, along with a controller to manage the display and provide driving assistance information, using a combination of main and sub-front patterns to enhance visibility and notification of the vehicle's state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional vehicle display device displays only the rearward view image, then the device structure remains simple, but the driving assistance capability is insufficient
Solution Approach 1:
The patent combines the forward view display and rearward view display into a single integrated display system. The display unit simultaneously presents the forward view image with superimposed front pattern and the rearward view image with superimposed rear pattern, merging multiple viewing functions into one unified interface that enhances driving assistance without proportionally increasing device complexity
Solution Approach 2:
The display unit is designed to perform multiple functions: displaying forward view, rearward view, vehicle position indicators (front and rear patterns), and driving assistance information. This multi-functional approach allows a single display system to provide comprehensive driving assistance coverage for both forward and backward directions
2Ease of operation
If the forward view image is displayed without a vehicle position indicator, then the display is simple, but the driver cannot intuitively understand the vehicle's position in the forward view
Solution Approach 1:
The front pattern is a simplified graphical representation (copy) of the vehicle's front view, superimposed on the forward image to indicate vehicle position. This graphical copy provides intuitive position information without requiring complex real-time 3D rendering or detailed vehicle model replication
Solution Approach 2:
The front pattern and rear pattern use distinct visual characteristics (such as color, brightness, or graphical style) to clearly differentiate vehicle position indicators from the actual road scene, enhancing the driver's ability to quickly recognize vehicle position without confusion
3Loss of information
If driving assistance information is not displayed, then the display unit shows only basic images, but the driver receives no notifications about driving state
Solution Approach 1:
The controller processes driving state information and provides visual feedback by displaying driving assistance information on the display unit. This feedback mechanism notifies the driver of the vehicle's driving state, such as lane position, distance to obstacles, or system status, creating a closed-loop information system

AI summary
A vehicle driving assistance device can include a display unit that displays a front pattern that is shaped like a vehicle front of a vehicle and is positioned within a forward view, and to superimpose the front pattern on a forward image that is an image of the forward view of the vehicle. A controller can be provided that can execute a process of controlling the display unit and causing the display unit to display driving assistance information for the vehicle, using the front pattern.
