The invention relates to an electro-hydraulic brake control device (1) for a motor vehicle, comprising at least two first output ports (4a, 4b) and two second output ports (4c, 4d) for at least four hydraulically actuatable wheel brakes (5a-5d), the invention relates to a hydraulic system (1) comprising first and second output ports (4a-4d), an electrically controllable hydraulic pressure source (2), a first electronically controlled regulating unit (A), a second electronically controlled regulating unit (B), a pressure medium reservoir (3), each first and second output port (4a-4d) having an inlet valve (6a-6d); each of the first and second output ports (4a-4d) has an outlet valve (7a-7d), via which each output port (4a-4d) is connected to the pressure medium reservoir (3), in which the pressure source (2) is formed by a cylinder-piston assembly having a pressure chamber (30), the piston (31) of which can be pushed back and forth by an electromechanical actuator (32, 33), the pressure chamber (30) is connected via a first electrically actuatable pressure-conducting valve (9, 19) to a brake line section (60) to which the at least four inlet valves (6a-6d) are connected, an electrical and/or electronic module is provided, which is configured, in the event of a failure of the first electronic control regulating unit (A), to control the brake line section (60) by means of the at least four inlet valves (6a-6d). Wherein, in the event of a failure of the second electronic control regulating unit (B), the electromechanical actuator (32) is actuated by the second electronic control regulating unit (B) and establishes a pressure for actuating the wheel brakes (5a-5d), and in the event of a failure of the second electronic control regulating unit (B), the electromechanical actuator (32) is actuated by the first electronic control regulating unit (A) and establishes a pressure for actuating the wheel brakes (5a-5d).
本发明涉及一种用于机动车的电液式制动控制器(1),包括用于至少四个可液压致动的车轮制动器(5a‑5d)的至少两个第一输出端口(4a,4b)和两个第二输出端口(4c,4d)、可电控的液压压力源(2)、第一电子控制调节单元(A)、第二电子控制调节单元(B)、压力介质储存器(3)、每个第一、第二输出端口(4a‑4d)各自具有的入口阀(6a‑6d);每个第一、第二输出端口(4a‑4d)各自具有的出口阀(7a‑7d),各输出端口(4a‑4d)经由相应的出口阀连接到压力介质储存器(3),其中,压力源(2)由具有压力室(30)的缸‑活塞组件形成,该缸‑活塞组件的活塞(31)可以由机电致动器(32,33)来回推动,其中,压力室(30)经由可电致动的第一压力导通阀(9,19)连接到制动管线区段(60),该至少四个入口阀(6a‑6d)连接到所述制动管线区段,其中,设置有电气和/或电子模块,所述电气和/或电子模块被配置为,在第一电子控制调节单元(A)失效的情况下,机电致动器由第二电子控制调节单元(B)操控并建立用于致动车轮制动器(5a‑5d)的压力,在第二电子控制调节单元(B)失效的情况下,机电致动器(32)由第一电子控制调节单元(A)操控并建立用于致动车轮制动器(5a‑5d)的压力。
