Vehicle Window Accentuation for Obstacle Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers often steer towards obstacles due to the psychological effect of looking where they want to avoid, leading to collisions and accidents, as existing methods require the driver to focus on both the obstacle and the swerving trajectory, reducing their ability to react effectively.
Innovation Solution
A driver assistance system that visually distracts from the obstacle by highlighting a swerving area through a warning signal, using sensors and accentuation devices like headlights or displays to create a virtual gate, directing the driver's attention to the safe path while obscuring the obstacle's view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the driver looks at the obstacle to identify it, then the driver can recognize the hazard, but the driver steers towards the obstacle due to psychological effect, worsening collision avoidance
Solution Approach 1:
The patent extracts the obstacle from the driver's visual field by having the accentuation device cover or obscure the obstacle's image on the windshield. This allows the driver to receive obstacle information through the warning signal without directly viewing the obstacle, thereby preventing the psychological effect of steering towards it while maintaining hazard awareness.
Solution Approach 2:
The patent introduces an intermediary system consisting of the sensor device, processor device, and accentuation device. This intermediary processes the obstacle information and presents it to the driver in a transformed way (through warning signals and covered representations) that conveys hazard information without triggering the harmful psychological steering response.
2Ease of operation
If the driver focuses on the calculated avoidance trajectory displayed on screen, then the driver can follow the swerving path, but the driver loses time concentrating on the trajectory and cannot react quickly enough
Solution Approach 1:
The patent extracts the trajectory guidance information from a separate display screen and integrates it directly into the driver's field of view on the windshield. The accentuation device highlights the swerving area and target corridor directly where the driver looks, eliminating the need to shift attention to a separate display and reducing reaction time.
Solution Approach 2:
The patent merges the hazard warning, trajectory guidance, and obstacle coverage functions into a single integrated display system on the windshield. The warning signal, covered obstacle representation, and accentuated swerving area are combined in one visual field, allowing the driver to receive all necessary information simultaneously without dividing attention.

AI summary
This disclosure relates to a method for assisting a user of a motor vehicle when swerving around an obstacle on a movement path of the motor vehicle. A driver assistance device carries out the following: providing a warning signal which describes an object on the movement path and a collision area which is visible through a window, preferably a vehicle window of the motor vehicle in which the object is located; defining a swerving area visible through the vehicle window, in which a swerving point for travelling around the object is visible, generating an accentuation signal, which describes a measure for accentuating the swerving area, and transmitting the accentuation signal to an accentuation device. Depending on the accentuation signal, the measure for accentuating the swerving area is carried out. The accentuation device can control a heads-up display, a monitor integrated into the vehicle window and/or a headlight.
