    • PROBLEM TO BE SOLVED: To improve practicability of a hydraulic brake system, in which a boosting linear valve 26 and a decompression linear valve 28 control pressure of hydraulic fluid supplied from a high pressure source device 22 and a brake control system 12 generates brake force whose magnitude depends on the controlled pressure.SOLUTION: The hydraulic brake system can selectively executes, as control of exciting current supplied to a boosting linear valve and a decompression linear valve: a feedback control based on deviation between actual servo pressure Pand target servo pressure; and a feedforward control, based on the target servo pressure, to be performed by achieving a valve opening/closing equilibrium state of the boosting linear valve and the decompression linear valve. The feedforward control supplies the boosting linear valve and the decompression linear valve with larger exciting current than the preset exciting current according to a relationship between the servo pressure and the exciting current in the valve opening/closing equilibrium state. Thereby securing sufficient brake force even in the feedforward control.

    • PROBLEM TO BE SOLVED: To make, as low as possible, a probability of switching to a backup mode in the case of detection of leakage abnormality of an ABS pressure reducing valve.SOLUTION: A pressure-increasing linear control valve is opened, with a master cut valve and a regulator cut valve closed and with a communication valve opened, to raise pressure until control pressure reaches P1 (S13-S14). Then, the pressure-increasing linear control valve is opened with the communication valve closed to raise the pressure again (S15-S16). If the control pressure drops, it is determined that the ABS pressure reducing valve has leakage abnormality (S17-S25). In this case, refreshing processing (S30) for allowing operating fluid to pass through the ABS pressure reducing valve is carried out without switching to the backup mode, and only when it is determined through subsequent reinspection (S90) that the abnormality is not removed, the mode is switched to the backup mode.

      解决方案:打开增压线性控制阀,主切断阀和调节器截止阀关闭,连通阀打开,以升高压力,直到控制压力达到P1(S13-S14)。 然后,增压线性控制阀打开,连通阀关闭,再次升高压力(S15-S16)。 如果控制压力下降,则确定ABS减压阀具有泄漏异常(S17-S25)。 在这种情况下,执行用于使工作流体通过ABS减压阀的刷新处理(S30)而不切换到备用模式,并且仅当通过后续的再次检查(S90)确定异常未被去除时, 模式切换到备份模式。 版权所有(C)2013,JPO&INPIT
