    • Three-position solenoid valve which outputs an output pressure and can adopt exhaust, overlapping and supply positions. The output pressure is detected by an output pressure sensor and is fed back to a fuzzy control unit. Based on the difference between the output pressure and the command pressure corresponding to the pressure command signal from the brake control unit, such fuzzy control unit calculates a command current value for controlling the three-position solenoid valve by fuzzy reasoning. The command current value can adopt an essentially continuous value, and consequently the three-position solenoid valve can adopt a gentle exhaust state or a gentle supply state. In this way, sudden changes in the output pressure can be suppressed and the output pressure can be made to converge rapidly on the command pressure and eliminate overshoot and undershoot.
    • 三位置电磁阀输出输出压力,可采用排气,重叠和供油位置。 输出压力由输出压力传感器检测并反馈到模糊控制单元。 基于与来自制动控制单元的压力指令信号对应的输出压力和指令压力的差异,这种模糊控制单元通过模糊推理来计算控制三位置电磁阀的指令电流值。 指令电流值可以采用基本上连续的值,因此三位置电磁阀可以采取温和的排气状态或温和的供给状态。 以这种方式,可以抑制输出压力的突然变化,并且可以使输出压力快速收敛于指令压力,并消除过冲和下冲。
