A vehicle control method that uses flow manipulation for gust response suppression was developed. A separation enhancement control technique that uses air injection is proposed. The yaw moment values for various aerodynamic side slip angles of a scale model car were measured. The results show that the proposed system reduces the yaw moment caused by a crosswind disturbance by 20 %. Additionally, the effective condition of air injection was examined using a fundamental wind tunnel test. Furthermore, a real-time modeling method is proposed for the flow condition around the car. A simple flow modeling method that uses a complex velocity potential is introduced, and the experimental results are compared with the theoretical results and discussed.
