ABSTRACT:
A fuzzy controller for Anti-Skid Brake System which utilizes fuzzy rules to avoid skidding and spinning of a vehicle during braking. The fuzzy controller includes: a solenoid valve installed in the brake device disposed on a wheel of the vehicle, capable of adjusting the brake torque exerted on the wheel; a sensor disposed on the wheel of the vehicle, for sensing dynamic states of the wheel in a real time manner and subsequently sending the dynamic states out of the wheel; a CPU coupled to the sensor, for processing data concerning the dynamic states coming from the sensor and sending the processed dynamic states data out; a fuzzy calculation circuit coupled to the CPU and provided with fuzzy rules stored therein, for receiving processed dynamic states data from the CPU and calculating the processed dynamic states data based on fuzzy rules stored therein and subsequently feeding calculated results back to the CPU so as to enable the CPU to send driving signals out in accordance with the calculated results; and a driving circuit coupled to the CPU and the solenoid valve, for receiving driving signals from the CPU and driving the solenoid valve to adjust the brake torque exerted on the wheel to obtain maximum largest frictional force between the wheel and the road during braking.
