The invention provides a single-cavity redundant drive-by-wire hydraulic brake system and a vehicle, and the single-cavity redundant drive-by-wire hydraulic brake system comprises a single-cavity main cylinder, a pedal simulator, a piston pump, at least one plunger pump and at least one brake wheel cylinder; the oil cavity liquid inlet end of the piston pump is connected with the liquid storage tank, and the oil cavity liquid inlet end of the plunger pump is connected with an oil cavity of the single-cavity main cylinder, the liquid storage tank and an oil cavity of the piston pump. An oil cavity of the brake wheel cylinder is connected with an oil cavity of the single-cavity main cylinder, an oil cavity of the piston pump and an oil cavity of the plunger pump, and the piston pump, the plunger pump and the single-cavity main cylinder are used for adjusting the pressure of the oil cavity of the brake wheel cylinder so that the brake wheel cylinder can brake wheels. According to the single-cavity redundant drive-by-wire hydraulic braking system and the vehicle, oil in the liquid storage tank can directly enter the oil cavity of the plunger pump and does not need to pass through an oil way of a piston pump and other components, and therefore the influence of the cut-off effect is avoided, and the pressure building speed of the plunger pump is increased.

    本公开提出一种单腔冗余线控液压制动系统和车辆,其中,单腔冗余线控液压制动系统,包括:单腔主缸、踏板模拟器、活塞泵、至少一个柱塞泵和至少一个制动轮缸;其中,活塞泵的油腔进液端和储液罐相连,且柱塞泵的油腔进液端分别与单腔主缸的油腔、储液罐和活塞泵的油腔相连;制动轮缸的油腔分别与单腔主缸的油腔、活塞泵的油腔和柱塞泵的油腔相连,且活塞泵、柱塞泵和单腔主缸用于调节制动轮缸的油腔压力,以使制动轮缸制动车轮。在本公开的一种单腔冗余线控液压制动系统和车辆中,储液罐中的油液能够直接进入到柱塞泵的油腔中,而无需经过活塞泵等部件的油路,从而避免了截流效应的影响,进而提高了柱塞泵的建压速度。
