    • A wheel slip ratio correction apparatus is disclosed which includes a calculation unit for calculating a slip ratio of each wheel when the brakes are not applied to either a front wheel or a rear wheel of a mobile vehicle such as a motorcycle. The calculation unit calculates a difference between a front wheel slip ratio and a rear wheel slip ratio, and changes in the slip ratio difference, which occur within a predetermined time period, are monitored by detecting if the slip ratio difference is stable and is within a predetermined range for a predetermined period of time. If the slip ratio difference is stable and is within the predetermined range for the predetermined period of time, a correction value, dependent upon the slip ratio difference, is subtracted from the greater of the front wheel slip ratio and rear wheel slip ratio so that any undesirable difference between the front and rear wheel slip ratios may be eliminated.

    • An estimated vehicle speed detection apparatus for motorcycles calculates an estimated vehicle speed based on a front wheel speed and a rear wheel speed and applies antilock brake control to each of front and rear wheels based on a calculated estimated vehicle speed. The apparatus includes a memory for storing the estimated vehicle speed at the time an application of antilock brake control to either the front or rear wheel is started, or an application of brakes to either the front or rear wheel starts. The apparatus further includes a calculation unit for comparing the front wheel speed and the rear wheel speed to calculate the estimated vehicle speed based on the higher of the front wheel speed or the rear wheel speed, while antilock brake control is applied to the front or rear wheel or either a front brake or a rear brake is applied.

    • An antilock brake control device controls the brake pressure of first and second rear wheels in accordance with one of a select-low mode and an independent mode. The select-low mode is carried out when the sum of the slip rates of the first and second rear wheels exceeds a predetermined value, and the independent mode is carried out when the sum of the slip rates of the first and second rear wheels is less than the predetermined value. In the select-low mode, control of the brake pressure applied to the first and second rear wheels is carried out in accordance with the rotation of the one of the first and second rear wheels having the slower wheel speed. In the independent mode, the braking control of each of the first and second rear wheels is independently carried out in accordance with the rotation of the first and second rear wheels, respectively.

    • Automotive hydraulic pressure brake system with a stroke simulator is proposed which while the electric control system is functioning properly, the supply of hydraulic pressure from a master cylinder is cut off and hydraulic pressure is generated by a power pump. This improves response upon rapid pressure increase while minimizing the increase of pedal stroke and the worsening of the pedal feeling. A bypass is provided to communicate the master cylinder to the wheel cylinders while bypassing an on-off valve to be closed during ordinary braking. A shut-off valve is provided in the bypass and a check valve or a relief valve for allowing only a fluid flow from the master cylinder toward the wheel brake cylinders is provided.
