Vehicle Periphery Display With Virtual Path Collision Cue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing periphery monitoring devices do not effectively allow drivers to intuitively grasp the positional relation between a detected object and their vehicle, especially when the object is on a collision course, leading to potential contact.
Innovation Solution
A periphery monitoring device that acquires the current steering angle and captures images of the vehicle's surroundings, displaying a synthesized image with a virtual vehicle image superimposed on the actual vehicle image, allowing the virtual vehicle to move towards the detected object and change display forms based on proximity, enabling intuitive recognition of potential collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a virtual vehicle image is displayed to show the future position of the vehicle, then driver awareness of potential collisions is improved, but display complexity and information overload increase
Solution Approach 1:
The virtual vehicle image dynamically changes its display state based on the detection results. When an object is detected on the expected course, the virtual vehicle image is displayed to show the future position. When no object is detected or the object is not on the course, the virtual vehicle image is hidden. This dynamic adjustment resolves the contradiction by making the display complexity adaptive rather than static.
Solution Approach 2:
The system calculates the expected course of wheels in advance and determines the future position of the vehicle before displaying the virtual vehicle image. This preliminary calculation allows the system to proactively display warning information before a collision actually occurs, improving driver awareness while maintaining controlled display complexity through pre-computed trajectories.
2Reliability
If the virtual vehicle image is continuously displayed, then the driver can always see the future vehicle position, but it becomes difficult to distinguish whether an object is on the collision course
Solution Approach 1:
The display system dynamically adjusts the visibility of the virtual vehicle image based on whether an object is detected on the expected course. When an object is present, the virtual vehicle image is displayed to indicate potential collision. When no object is present, the virtual vehicle image is hidden to avoid obscuring the view. This dynamic on/off switching resolves the contradiction by making the display state conditional rather than continuous.
Solution Approach 2:
The system applies different display qualities to different situations: the virtual vehicle image is displayed only in the specific local condition when an object is detected on the expected course, rather than uniformly across all situations. This localized application of the display feature maintains position recognition information while preserving collision course information.

AI summary
A periphery monitoring device includes: an acquisition section (401) acquiring a steering angle of a vehicle (1); an image acquisition section (400) acquiring a captured image from an image capturing section (15) that captures an image of a periphery of the vehicle; a detection section (402) acquiring detection information of an object (O) around the vehicle; and a control section (403) causing a display section (8) to display a synthesized image including a vehicle image (G1) showing the vehicle and a periphery image (G2) showing the periphery of the vehicle based on the captured image. When the object is detected on a course of the vehicle traveling at the steering angle by a predetermined distance, the control section causes a virtual vehicle image (G5) to be displayed in the synthesized image to be superimposed on a course to the object with a position of the vehicle as a reference.
