Researchers focus on enhancing the aerodynamic performance of autonomous vehicles by reducing drag induced by externally mounted sensors such as cameras and light detection and ranging instruments. After establishing an automated computational platform, they combined the experimental design with a substitute model and an optimization algorithm to improve the structural shapes of AV sensors. They then performed simulations of both the baseline an…

Autonomous vehicles (AVs) are becoming an integral part of modern transportation, thanks to advancements in information technology and artificial intelligence. These innovations have made it possible for AVs to handle tasks like logistics delivery and low-speed public transportation. However, challenges remain, particularly in enhancing their aerodynamic performance, which is critical for reduci

If you live in one of the roughly dozen US cities where autonomous vehicles are present, you likely recognize them by their eye-catching, spinning tops. These high-tech flappers are filled with sensors—usually a mix of LiDAR, radar, and cameras—that serve as the eyes and ears for AVs to map the world around them. But those sensor stacks are often bulky, which can impede a car’s ability to cut through the air around it. That hindrance can force t…

Deformation control volumes are set for the front sensor, front-side sensor, roof sensor, and rear-side sensor, which affect the aerodynamic drag coefficient. The sensor shapes can be modified by adjusting the control points. Credit: Yiping Wang Thanks to the rapid progress of information technology and artificial intelligence, autonomous vehicle technology has been taking off. In fact, AVs are now advanced enough that they are being used for lo…
