摘要： A braking control system for a motor vehicle in which various braking controls, including an antiskid braking control and a traction control, are realized comprehensively, accurately and smoothly without being based on the slip factor of a wheel. The actual wheel speed (Wvr) of the rear wheel side is detected, and the desired wheel speed (Wrf) of the front wheel side is set so as to be lower than the actual wheel speed (Wvr). Besides, the actual wheel speed (Wvf) of the front wheel side is detected, and the deviation (ef) between the actual wheel speed (Wvf) and the desired wheel speed (Wrf) is detected. Subsequently, the desired braking torque (Nrf) of the front wheel side is calculated from the deviation (ef) and the actual wheel speed (Wvf). Further, the desired braking torque (Nrr) of the rear wheel side is set on the basis of the desired braking torque (Nrf). The braking pressure of the braking apparatus is controlled so as to establish the desired braking torques (Nrf) and (Nrr).

摘要： A braking force control system for a motor vehicle, in which a hydraulic pressure control device controls a hydraulic pressure generated by the master cylinder or the pump, in such a way that a target braking torque (Nr in FIG. 1) is calculated from a target slip factor (Sr) and an actual slip factor (S), the target braking torque (Nr) is converted into a target braking hydraulic pressure (Pr), and that an estimative braking hydraulic pressure (P) currently under action is calculated by the use of a hydraulic pressure model, while the controlled variable of the hydraulic pressure control device is calculated from the estimative braking hydraulic pressure (P) and the target braking hydraulic pressure (Pr) by the use of a reverse hydraulic pressure model. Thus, the hydraulic pressure can be controlled in conformity with the actual motion state of the motor vehicle.
