Vehicle Control Device Prioritizes Recognizable Deceleration Targets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle control systems, when multiple conditions for automatic deceleration are met simultaneously, the driver may experience discomfort due to difficulty in visually recognizing the object triggering the second condition, leading to potential confusion and increased display area requirements for showing both objects.
Innovation Solution
The vehicle control device prioritizes displaying information about the object easier for the driver to recognize, using a processor that determines the relevance of objects within specific visually recognizable areas, and executes deceleration control based on predefined conditions, displaying only the image of the second object when the first object is outside the driver's visual area, thus avoiding confusion and reducing the need for a large display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If images representing both the first object and the second object are displayed on the display device when multiple deceleration conditions are met simultaneously, then the driver can understand the deceleration control triggers, but the driver may experience discomfort if the first object is outside the visual recognition area and the second object is inside it
Solution Approach 1:
The patent extracts and displays only the object that is within the driver's visual recognition area when multiple objects are detected. The processor determines the visual recognition area based on the camera's field of view and selectively displays only the relevant object (the second object inside area A1) while excluding objects outside the visual area (the first object in area A2), thus resolving the contradiction between information completeness and driver comfort.
2Loss of information
If images representing both the first object and the second object are displayed simultaneously, then all deceleration triggers are shown, but a relatively large display area is required
Solution Approach 1:
The patent extracts and displays only the necessary object information - specifically the object within the visual recognition area. By filtering out the object outside the visual area (first object) and displaying only the object inside the visual area (second object), the system maintains information completeness for the driver's perspective while significantly reducing the required display area.
3Loss of information
If the processor displays information about objects triggered by deceleration conditions, then the driver can understand the control reasons, but driver discomfort occurs when the displayed object cannot be visually recognized
Solution Approach 1:
The patent extracts the object that is actually visible to the driver (second object within area A1) and displays only that object. By removing the invisible object (first object in area A2) from the display, the system ensures that all displayed information corresponds to objects the driver can visually recognize, thereby maintaining information transparency while eliminating the harmful effect of driver discomfort.
Solution Approach 2:
The patent applies different display strategies based on the local property of object positions - objects within the visual recognition area (area A1) are displayed, while objects outside this area (area A2) are not displayed. This local quality approach ensures that information is provided only where it can be effectively perceived by the driver, resolving the contradiction between information transparency and driver comfort.

AI summary
The processor, under circumstances where both the first and second conditions that decelerate the own vehicle are met, and deceleration control triggered by the establishment of the first condition is being preferentially executed, controls the image display. This happens when the first target involved in the establishment of the first condition is located outside a specific area extending forward from the own vehicle, which is a part of the detection area of the forward sensor and set as an area visible to the driver. Simultaneously, if the second target involved in the establishment of the second condition is located inside this specific area, the processor displays the second information about the second target on the image display device and does not display the first information about the first target.
