The invention relates to the technical field of automobile braking, and discloses a drive-by-wire electronic hydraulic braking system suitable for a minicar. The system mainly comprises a liquid storage tank, a braking master cylinder, a displacement sensor, an electronic control unit and a hydraulic execution unit. Wherein the hydraulic execution unit comprises a pressure regulating normally-closed valve, an emergency braking normally-open valve, a plunger pump, a decoupling plunger pump and a motor; a vacuum booster and a vacuum pump are not used, and assistance is provided for braking in the mode that a motor drives a plunger pump. The electromagnetic valve is used for controlling the braking pressure so as to realize the braking function; and the product has the characteristics of small size, low cost, high brake speed and good durability.

    本发明公开了一种涉及汽车制动技术领域、适用于微型汽车的线控电子液压制动系统,系统主要包括储液罐、制动主缸、位移传感器、电子控制单元、液压执行单元;其中,液压执行单元包括调压常闭阀、紧急制动常开阀、柱塞泵、解耦柱塞泵、电机;不使用真空助力器、真空泵,采用电机驱动柱塞泵的方式为制动提供助力;用电磁阀控制制动压力的大小从而实现制动功能;具有体积小、成本低、制动速度快、耐久性好的特点。
