Abstract
PURPOSE: To control wheel speed to maintain an instantaneous value of a coefficient of friction of road surface μ close to the maximum value by calculating the value by an equation of motion which is based on electric signals each of which corresponds to wheel speed acceleration and deceleration, a brake torque, and a wheel weighting.
CONSTITUTION: A signal to judge increase or decrease of an output signal of coefficient of friction of road surface μ by discriminating whether a differential value is positive or negative by differentiating μ of coefficient of friction of the road surface detecting device 5 at a coefficient of friction increase or decrease discriminating part 6. At an actuator control part, responding to a μ reduction discriminating signal, a reduction in brake hydraulic pressure is instructed when the brake hydraulic pressure has been increased, and an actuator control signal is generated to increase when the pressure has been reducing. Being thus constituted, wheel speed is controlled to maintain the coefficient of friction of road surface μ close to the maximum value. When the same control signal keeps on being generated for longer than a set period of time and μ signal wouldn't change in the direction of increase, a timer part 9 switches control signal to the control part 7.
