Abstract
In order to improve the safety of road vehicles, various active safety systems have been proposed and developed. These active safety systems include active forward / backward steering, differential braking, active roll moment control, etc. In essence, the longitudinal, transverse and vertical dynamics of the vehicle are controlled from the perspective of tire mechanics, which has the disadvantage that the tire is easy to be saturated under limit conditions. This paper summarizes the control schemes of active aerodynamics to improve vehicle handling stability. When the vehicle is running at high speed, aerodynamics has a great influence on the vehicle, which greatly reduces the handling stability of the vehicle. Low handling stability may lead to unstable motion patterns. In order to improve the lateral stability, various control schemes considering relevant performance measures are designed and evaluated by numerical simulation or experimental methods. This paper focuses on the active aerodynamic control scheme, analyzes its characteristics, and determines the future research work.
