1. An antiskid brake control system for a vehicle, comprising;
- sensing means for sensing behaviors of a vehicle body and a vehicle wheel of the vehicle,preparing means connected with said sensing means for determining parameters representing the behaviors of the vehicle body and wheel,fuzzy inference means for storing predetermined membership functions each of which is a function of one of said parameters, determining values of said membership functions by using said parameters, and determining a manipulated quantity in accordance with said values of said membership functions, andmodulator means for varying a brake actuation force applied to said vehicle wheel in accordance with said manipulated quantity.

Abstract
An antiskid brake control system of a vehicle includes a detecting section for sensing or estimating various parameters such as vehicle speed, wheel speed, wheel slip rate, first time derivatives of the vehicle speed and wheel speed, and second time derivative of the vehicle speed and wheel speed, a control section for determining a manipulated quantity by a fuzzy inference based on the values of the parameters, and a modulator section for varying a brake fluid pressure in accordance with the manipulated quantity.
