Intelligent Vehicle In-Loop Test System with Rotary Drum and Virtual Projection

The patent replaces the mechanical limitation of a program-controlled electric vehicle with a virtual reality simulation system. The high-speed oncoming vehicle scenarios are simulated through visual projection and virtual environment creation, allowing the test vehicle to experience high-speed approach scenarios without requiring a physically high-speed target vehicle. This resolves the contradiction by substituting physical mechanical speed limitations with virtual environmental simulation.

The patent creates virtual copies of high-speed target vehicles through projection systems and virtual reality environments. Instead of using a physical electric vehicle that cannot achieve high speeds, the system projects virtual images of high-speed oncoming vehicles and creates corresponding virtual environmental parameters (wind resistance, audio cues, etc.) to replicate the sensory experience of high-speed approach scenarios.

The patent transforms the fixed test platform into a dynamic system with multiple degrees of freedom. The test vehicle platform is equipped with rotation mechanisms that allow autonomous rotation and positioning, enabling the vehicle to simulate lane changes, curve driving, and other complex movements. The system dynamically adjusts the platform orientation and position based on the simulated driving scenario requirements.

The patent creates a multi-functional test platform that can perform multiple operations: longitudinal movement simulation, transverse movement simulation, autonomous rotation, and virtual environment projection. This universal platform replaces the need for multiple separate test devices, achieving high adaptability for various driving scenarios while managing complexity through integrated design.

The patent introduces a virtual reality environment as an intermediary between the static test platform and the sensor devices. The virtual environment projects realistic road scenes, lane markings, and environmental features that move and change according to the simulated vehicle motion. This intermediary allows the sensors to detect and record data as if in a real dynamic environment, while the physical platform remains relatively simple.

The patent adds a virtual dimension to the physical test environment. By projecting three-dimensional virtual road environments and lane markings that move and transform according to simulated vehicle motion, the system creates a multi-layered testing space where sensors can detect both virtual and physical stimuli, achieving high measurement precision without requiring complex physical environmental changes.
