Deceleration Target Display Logic for Driver Assistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving assistance systems fail to accurately notify occupants of changes in deceleration targets, leading to potential misrecognition of the current target for deceleration assistance, which can cause confusion and safety issues.
Innovation Solution
A driving assistance apparatus with a controller that manages a display system to differentiate between primary and secondary deceleration targets by displaying first notification information for the current target in a prominent area and secondary notification information for previously relevant targets in a less visible area, ensuring the occupant remains aware of both.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display apparatus continues to display the first deceleration object that is not the current target for deceleration assistance process, then the occupant remains aware of all detected objects, but the occupant may erroneously recognize the deceleration object that is the target for the deceleration assistance process
Solution Approach 1:
The patent applies local quality by differentiating the display characteristics of the first deceleration object from the second deceleration object. The first object (previously targeted) is displayed with reduced visibility or in a different visual style compared to the second object (current target), allowing the occupant to distinguish which object is the active target while still being aware of other detected objects.
Solution Approach 2:
The patent segments the information display by separating the notification of the current target object from the notification of other detected objects. This segmentation allows the system to provide differentiated visual feedback, where the current target receives prominent display treatment while other objects are displayed in a manner that indicates they are not the active target.
2Reliability
If the display apparatus displays only the current target deceleration object, then the target recognition accuracy is improved, but the occupant loses awareness of other relevant detected objects
Solution Approach 1:
The patent merges multiple pieces of information on the display apparatus by showing both the current target object and other detected objects simultaneously. This combining approach ensures the occupant receives comprehensive information about all detected deceleration objects while the visual differentiation maintains clear target identification.
3Loss of information
If the display apparatus displays multiple deceleration objects simultaneously, then complete information is provided to the occupant, but the display complexity and potential for occupant confusion increases
Solution Approach 1:
The patent reduces display complexity by applying local quality differentiation, where the current target object is highlighted with distinct visual characteristics while other objects are displayed with subdued characteristics. This approach maintains information completeness while simplifying the visual hierarchy and reducing potential occupant confusion.

AI summary
A driving assistance apparatus includes a controller programmed to perform a deceleration assistance process of assisting in decelerating a vehicle before the vehicle arrives at a deceleration object, and to control a display apparatus to display, in a first display area, first notification information for notifying an occupant of the vehicle of the deceleration object that is a target for the deceleration assistance process. When a first object and a second object that is different from the first object are both detected as the deceleration object and the second object is the target for the deceleration assistance process but the first object is not the target for the deceleration assistance process, the controller is programmed to control the display apparatus to display, in a second display area, second notification information for notifying the occupant of the first object, the second display area is different from the first display area.
