AI Technical Summary
Existing fog environment testing equipment cannot measure visibility at multiple points, resulting in a bias in the degree of fog environment simulation and making it difficult to comprehensively evaluate the vehicle's perception and response capabilities in complex fog environments.
Employing a height-adjustable visibility meter and fog delivery assembly, the height of the visibility meter within the test hood is adjusted via a lifting push rod. Combined with multi-point nozzles and uniform fog distribution, this ensures the accuracy of visibility measurements and the realism of environmental simulation.
It enables visibility measurement at different altitudes, improves the relevance and accuracy of fog environment testing, adapts to the testing needs of different vehicle models, and has versatility and efficient fog control.
