Problems solved by technology
However, the jet direction of the traditional blowing device is often not adjustable, and only a fixed jet angle is selected.
However, many studies have shown that the effect of angle on aerodynamic drag varies widely in different situations

Description
technical field [0001] The invention relates to an automobile aerodynamic drag increase control system, in particular to an automobile aerodynamic drag increase control system and method based on a variable-angle air blowing device. Background technique [0002] When a car is running at high speed or on a downhill road, its braking performance is closely related to driving safety. Increasing the driving resistance during the braking process of the car and reducing the braking distance of the car play an important role in driving safety. Studies have shown that for a typical passenger car, when the vehicle speed exceeds 60km / h, nearly 50% of the driving resistance comes from aerodynamic resistance, and the aerodynamic resistance is linearly proportional to the square of the vehicle speed. It can be seen that increasing the aerodynamic resistance of the car is of great significance to the safety of the car braking process, especially in the emergency braking state. [0003] ...
