VEHICLE BRAKING SYSTEM FOR DRIVE WHEELS, HAVING MEANS FOR DELAYING COMMENCEMENT OF BRAKE PRESSURE CHANGE

摘要

A braking system including a hydraulically operated brake for braking a drive wheel of a motor vehicle, a slip detector for detecting an amount of slip of the drive Wheel, and a pressure-regulating controller for increasing or decreasing a fluid pressure to be applied to the brake, in response to each output signal of the slip detector, whose value indicates a pressure-increase or pressure-decrease condition which requires an increase or decrease in the fluid pressure, respectively, such that the amount of slip of the drive wheel is maintained within an optimum range. The braking system incorporates a device for commanding the pressure-regulating controller to delay commencement to increase and/or decrease the fluid pressure to be applied to the brake, with respect to a part of the occurrences of the pressure-increase condition and/or the pressure-decrease condition, for a predetermined time duration as measured from a point of time at which the pressure-increase and/or said pressure-decrease condition is/are established.
