Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control system tests in automated driving assistance systems face challenges in evaluating vehicle behavior in real-time due to the use of virtual objects and sensors that cannot be directly visually recognized, making it difficult to assess the appropriateness of vehicle responses to virtual detections.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If virtual objects and virtual sensors are used for testing vehicle control systems, then the preparation period is reduced and various travel environments can be simulated, but the detection results cannot be visually recognized in real-time, making it difficult to evaluate vehicle behavior
Solution Approach 1:
The patent introduces an image generation unit as an intermediary that converts invisible virtual sensor detection data into visible image data. This mediator translates the undetectable virtual object information into a form that can be visually perceived, allowing observers to see the detection results without requiring physical virtual objects or sensors
Solution Approach 2:
The patent creates a visual copy of the virtual sensor's detection results by generating images that represent the detection data. Instead of using the actual virtual sensor output directly, the system produces an image representation that copies the essential information in a visually accessible format
2Ease of manufacture
If virtual sensors are used to detect virtual objects, then the system can operate without physical sensors and objects, but the search waves and reflected waves cannot be visually recognized, preventing real-time evaluation
Solution Approach 1:
The patent replaces the physical mechanical sensor system with a computational image generation system. Instead of using actual sensors that transmit physical waves, the system uses image generation units that computationally simulate and visualize the wave travel states, substituting physical detection with optical visualization
3Adaptability or versatility
If virtual objects are arranged on a real field for testing, then various travel environments can be created without physical reconfiguration, but the detection results remain invisible to occupants and observers
Solution Approach 1:
The patent uses color and visual representation changes to make invisible detection data visible. The image generation unit creates visual representations with different colors and intensities to represent various detection states, allowing observers to perceive the virtual object detection results through color-coded visual feedback
Data Source
AI summary
A vehicle operation simulator system includes: a virtual object arrangement unit arranging a virtual object on a real field; a virtual object detection unit detecting the virtual object by, using a virtual sensor installed at a predetermined installation position in a predetermined installation direction in a vehicle, pseudo-simulating transmission of a search wave from the installation position to surroundings of the vehicle along the installation direction and reception of a reflected wave of the search wave reflected by the virtual object around the vehicle; and an image visual recognition unit causing the real field to be visually recognized, the real field being superimposed with at least one of a search wave image indicating a travel state of the search wave transmitted from the virtual sensor and a reflected wave image indicating a travel state of the reflected wave when the search wave is reflected by the virtual object.
