Wind resistance deceleration system capable of shortening braking distance of vehicle

Abstract

The invention discloses a wind resistance deceleration system capable of shortening the braking distance of a vehicle, the system comprises a start button, a controller and a deceleration system, the deceleration system is composed of a sliding cavity, a sliding column driving device, a sliding column, a servo device and a deceleration parachute; when the vehicle is braked emergently at a high speed, a driver finds that the speed reduction degree of the vehicle is too small, the start button can be pressed down, after the controller receives a start signal, the deceleration system is instructed to work, the deceleration parachute is automatically opened, the vehicle is decelerated through wind resistance, and the wind resistance can be controlled by controlling the opening angle of the deceleration parachute; according to the system, on the basis of not changing the original dynamics of the vehicle, the driving resistance of the vehicle is increased, the braking distance of the vehicle is shortened, the operation such as steering of the driver cannot be affected, meanwhile, the wind resistance can be automatically adjusted, the structure is simple, and the application is easy.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a windage deceleration system for shortening the braking distance when the vehicle is in emergency braking at high speed (vehicle speed greater than 50 km / h). Background technique [0002] Excessive braking distance and inability to stop the car are the main reasons for many safety accidents, especially on high-speed and snowy and slippery roads; The braking distance to stop will also be greater than 30 meters. For example, BYD's Han is equipped with the best braking system. The braking distance per 100 kilometers is 32.8 meters, which is the best indicator in the world at present. The average car is more than 40 meters, or even 50 meters. ; Only rely on the current vehicle chassis braking system, can not solve the problem that the braking distance is too long. When the vehicle is at high speed, if an obstacle suddenly appears in front of the vehicle, even if the brake pedal is...
