Automatic skid reduction control method and device for a braking system

摘要

An automatic brake controlling method and device for applying brake pedal forces to a wheel of a moving vehicle, includes acceleration detecting apparatus for detecting the acceleration of a moving vehicle; wheel velocity detecting apparatus for detecting a wheel speed of the moving vehicle; feedback apparatus for computing the vehicle velocity by integrating the detected acceleration, comparing the vehicle velocity and the wheel velocity, feeding back the difference signal between the vehicle velocity and the wheel velocity, and memorizing the difference signal; auxiliary feedback apparatus for feeding back an electrical signal according to the difference signal; computing apparatus for computing whether a slip ratio of said wheel velocity to said vehicle velocity is larger than a predetermined value or not; and controlling apparatus for controlling the brake force to a reduced level whenever said slip ratio is larger than said predetermined value on the application of the brake, thereby compensating the operational error of said integrator apparatus when the brake is gently applied for a long time.
