Vehicle Maneuver Projection System for Danger Zone Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to effectively warn both drivers and other road users of potential danger areas created by a vehicle's upcoming driving maneuvers, particularly for large vehicles like buses and trucks, as existing solutions do not accurately depict the future traffic area, leaving users uncertain about the actual danger zone.
Innovation Solution
A procedure that uses sensors to determine the vehicle's steering angle and direction of travel, feeding this information into a control system to project the future traffic area onto the ground using a light projection, allowing both drivers and other users to visualize the danger zone, with the option to include additional graphic information like stop symbols for enhanced clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If signal sources are provided on the vehicle to warn road users of dangers, then the information situation of road users is improved, but the actual danger area remains unclear to them
Solution Approach 1:
The patent projects a light pattern onto the ground that replicates the future occupied traffic area. This optical copy allows road users to see exactly where the vehicle will be, transforming abstract warning signals into a precise visual representation of the danger zone.
Solution Approach 2:
The patent transitions from providing only auditory or simple visual warnings to projecting a two-dimensional light pattern onto the ground plane. This adds a spatial dimension to the warning system, allowing road users to perceive the extent and location of the danger area directly on the surface they are traveling on.
2Loss of information
If the future traffic area is projected onto the ground, then both drivers and road users recognize the danger area, but the system complexity increases
Solution Approach 1:
The patent uses a single projection system that serves multiple functions: it provides spatial information to road users, confirms the danger area to the driver, and can potentially indicate different maneuver types. This multi-functionality reduces the need for separate warning systems for different user groups.
Solution Approach 2:
The projection system automatically determines the future occupied traffic area using the vehicle's existing sensor data and steering model, then displays it without requiring manual input. The system serves itself by utilizing already-available vehicle data to create the warning display.

Function Achieved in This Case
This solution enables immediate recognition of potential collisions by both drivers and other road users, allowing them to take necessary precautions and preventing accidents by clearly delineating the danger area before a maneuver occurs.
Implementation Method 1
at least one projection facility (4.1 to 4.4), which is obtained in this way, controls at least one projection facility in such a way that at least part of the future traffic area is visible through a light projection on the floor area surrounding the vehicle is made

AI summary
The invention relates to a method and an arrangement for warning road users of potential danger zones created by a vehicle performing or intending to perform a driving maneuver. A control unit (8) is provided which uses at least one steering angle sensor (10) to query the steering angle of the vehicle, queries the direction of travel from a gear selector (11), and, using a steering model of the vehicle accessible to the control unit (8), cyclically determines a traffic area from the steering angle and the direction of travel that will be occupied in the future if the steering angle is maintained within a predefinable time and speed. It is further provided that at least one projection device (4.1, 4.2, 4.3, 4.8) uses the information thus obtained about the traffic area that will be occupied in the future to display a visual representation of the vehicle.4) is controlled in such a way that at least part of the future occupied traffic space is made visible by a light projection onto the ground surface surrounding the vehicle.
