    • A brake control system includes devices for determining wheel r.p.m. for determining an acceleration rate of the wheel r.p.m. and generating a signal when the determined acceleration rate becomes equal to or greater than a predetermined value, and for determining a target wheel r.p.m. based on the wheel r.p.m. The target wheel determining device is operatively responsive to detection of the peak of the coefficient of friction. A control device is provided for controlling applying and releasing of fluid pressure to wheel cylinders for skid controlling the wheel deceleration rate. The target wheel r.p.m. determining device determines the rate of deceleration of wheel r.p.m. based on the difference of wheel r.p.m. between the detection time of a peak of the coefficient of friction and the detection time of the immediately preceding peak and on the length of the period between detections of the peaks. The device thereby determines the target wheel r.p.m. by subtracting a deceleration value, obtained as a function of the determined rate of deceleration, from the wheel r.p.m. determined at the time of detecting of the peaks of the coefficient of friction.

    • An acceleration sensor acts on the variable-frequency pulses of a speed sensor signal to recognize any variation of the pulse period thereof and to produce an output indicative of the magnitude of the detected variation to within a fixed degree of accuracy. The periods of groups of known, variable number pulse groups are measured with reference to a fixed-frequency clock pulse signal and the measurement periods of successive groups of equal numbers of pulses are compared. If the difference between pulse group periods is zero or less than a predetermined value, the number of pulses in each group is increased in order to increase the total number of clock pulses during the measurement interval. The number of pulses per group is increased until the difference between measured periods exceeds the predetermined value or until the number of pulses per group reaches a predetermined maximum. Acceleration rate calculations and memory control procedures are designed to take into account the variation of the number of pulses per group.

    • Disclosed is a brake control system for an automotive vehicle for controlling application and release of brake pressure in order to prevent the vehicle from skidding. The system includes a sensing circuit for determining wheel r.p.m., a deceleration detecting circuit for determining a deceleration rate of the wheel r.p.m. and generating a signal when the determined deceleration rate becomes equal to or greater than a predetermined value, a target wheel speed circuit for determining a target wheel r.p.m. based on the wheel r.p.m. and operative responsive to detection of a peak of the coefficient of friction between the vehicle wheel and the road, and a control circuit for controlling application and release of brake fluid pressure to wheel cylinders for controlling the wheel deceleration rate. The target wheel speed circuit is operative to determine a rate of deceleration of wheel r.p.m. based on the difference in wheel r.p.m. between the time of detecting the peak coefficient of friction and the time of detecting the immediately preceding peak. The target wheel r.p.m. is further based on the length of time between detection of the peaks and is determined by subtracting a deceleration value, based on the determined rate of deceleration, from the wheel r.p.m. determined at the time of detecting of the peak of coefficient of friction.
