Vehicle Display Control for Clear Deceleration Mode Differentiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing advanced driver-assistance systems (ADAS) in vehicles do not effectively distinguish between different deceleration assistance modes, leading to potential driver confusion due to similar control behaviors being perceived as the same, necessitating clearer display formats for deceleration assistance.
Innovation Solution
A display control device and method that adjusts the display format of deceleration assistance images to match the display format of the driving mode image, using color, thickness, or size to differentiate between deceleration assistance modes such as deceleration assistance, adaptive cruise control, and congestion following, ensuring easy recognition by the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If deceleration assistance is provided across multiple driving assistance modes (deceleration assistance mode, ACC mode, congestion following mode), then the versatility and usefulness of the driving assistance system is improved, but the driver may become confused about which specific mode is active due to similar control behaviors
Solution Approach 1:
The patent applies local quality by making the deceleration assistance image have different display formats (color, thickness, size) depending on the specific driving assistance mode. The deceleration assistance image is displayed in a first display format when deceleration assistance mode is active, and in a second display format when ACC mode or congestion following mode is active. This localized differentiation in display properties allows the driver to distinguish between modes while maintaining consistent deceleration assistance functionality across modes.
2Loss of information
If different display formats are used for deceleration assistance images in different driving assistance modes, then the clarity of mode identification is improved, but the complexity of the display system increases due to managing multiple display formats
Solution Approach 1:
The display control device implements local quality by applying different display formats selectively to the deceleration assistance image based on the active driving assistance mode. The control unit changes at least one display format parameter (color, thickness, or size) of the deceleration assistance image according to the detected mode, allowing clear mode differentiation without requiring completely separate display elements for each mode.
