Abstract
PURPOSE:To improve the start-up of a between-cars deceleration by providing a means to detect the variation width of a frictional coefficient on a road surface, and carrying out a small pressurization for the correction of a frictional coefficient variation when this variation width has become more than a predetermined value. CONSTITUTION:A brake pressure control actuator 3 conducts the pressurization, maintenance and depressurization of the brake pressure of the brake 4i of each car wheel on the basis of the result of the decision of a main brake pressure controller 15 and an integration type brake pressure controller 16. Hereupon, the integration type brake pressure controller 16 is equipped with a timer function and a counter function, and when, for example, the brake pressure of the right and left front wheels has not been depressurized over a predetermined time, it is decided that a frictional coefficient on a road surface has become rapidly larger than a predetermined variation width. In this instance, a small pressurization command for the correction of a frictional coefficient variation is issued, thus heightening quickly the brake pressure, and the deceleration shortage of a car body at the time of moving onto a hard to slip road surface is dissolved.
