SPThe present disclosure provides an electro-hydraulic brake system and a pressure supply unit therefor. The electro-hydraulic brake system includes a master cylinder (MC) fluidly coupled to an MC fluid passage and configured to supply fluid into the MC fluid passage in response to a pressing force on a brake pedal. A pressure supply unit (PSU) includes an electric motor and a PSU piston disposed within a piston bore, the PSU piston being movable by the electric motor through the piston bore and dividing the piston bore into a first chamber and a second chamber. A pedal feel simulator (PFE) includes a PFE piston movable through the PFE bore and separating the upper chamber from the lower chamber. In response to compression of the PFE, fluid is transferred from a lower chamber of the PFE to a second chamber of the PSU. The MC fluid passage provides a fluid path from the master cylinder to the upper chamber of the PFE.
本公开提供一种电液制动系统及用于其的压力供应单元。一种电液制动系统包括主缸(MC),其流体地联接到MC流体通路并且被配置为响应于制动踏板上的按压力而将流体供应到MC流体通路中。压力供应单元(PSU)包括电动马达和设置在活塞孔内的PSU活塞,PSU活塞可由电动马达移动通过活塞孔并将活塞孔分成第一腔室和第二腔室。踏板感觉模拟器(PFE)包括可移动通过PFE孔并将上腔室与下腔室分隔开的PFE活塞。响应于PFE的压缩,流体从PFE的下腔室传送到PSU的第二腔室。MC流体通路提供从主缸到PFE的上腔室的流体路径。
