Vehicle Detection Range Projection for Pedestrian Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle travel control systems do not effectively communicate the detection range of obstacles to pedestrians or other vehicles, as the attention-arousing patterns projected onto the road surface do not represent the vehicle's detection capabilities.
Innovation Solution
A vehicle travel control method and apparatus that uses pattern display devices to visually indicate the detection range of objects on the road surface, allowing pedestrians and others to recognize whether they are within the vehicle's detection range by adjusting the pattern size and position based on the object's proximity and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a predetermined pattern is projected onto the road surface to arouse attention, then the attention of other vehicles and pedestrians is aroused, but the detection range for objects cannot be recognized by pedestrians
Solution Approach 1:
The pattern display device changes the color or luminance of the projected pattern to indicate different detection states. When an object is detected, the pattern color or brightness changes to communicate the detection status to pedestrians, making the detection range visible and understandable.
Solution Approach 2:
The projected pattern dynamically adjusts its properties (position, size, shape, or intensity) based on the detected object's location and distance. The pattern is displayed at positions corresponding to the detection range, and its characteristics change in real-time to reflect the vehicle's detection capability and status.
2Loss of information
If the pattern size and position are adjusted based on object proximity and movement, then the detection range recognition is improved, but the device complexity increases
Solution Approach 1:
The system uses feedback from the object detector to automatically adjust the pattern display. The object detector provides real-time information about detected objects, and this feedback is used to control the pattern's position, size, and intensity, creating a closed-loop system that simplifies the control mechanism while maintaining high information transmission effectiveness.
Solution Approach 2:
The pattern display device serves multiple functions: it arouses attention, indicates detection range, communicates object detection status, and provides spatial information about the detection zone. By making the pattern display multi-functional, the system reduces the need for separate devices for each function, thereby managing complexity while achieving multiple goals.

AI summary
The disclosure includes, when controlling a vehicle (V) having an autonomous travel control function to travel autonomously, detecting whether or not an object (H) is present around the vehicle and displaying a predetermined pattern corresponding to a detection range at a certain position on a road surface toward the detection range so that the predetermined pattern is visible.
