The invention relates to a brake system (100) for a motor vehicle, comprising electromechanical wheel brakes (104, 106, 108, 110), a brake actuation unit (112) and a central brake control unit (102), the wheel brakes (104, 106, 108, 110) each having a local brake control unit (118, 120, 122, 124). The central brake control unit (102) is directly connected via a first data connection (154) to the brake operating unit (112) and to the local brake control unit (118, 120, 122, 124) of the wheel brakes (104, 106, 108, 110), and the brake operating unit (112) is directly connected via a second data connection (156) to the local brake control unit (118, 120, 122, 124) of at least one wheel brake (104, 106, 108, 110). In a normal operating mode of the brake system (100), the central brake control unit (102) is configured to determine at least one braking demand in dependence on first operating information of the brake operating unit (112), in particular received via the first data connection (154), and to transmit a control signal corresponding to the braking demand to the wheel brakes (104, 106, 108, 108). The present invention relates to a local brake control unit (118, 120, 122, 124) for a vehicle (100, 110). In a backup level operating mode of the brake system (100), the local brake control units (118, 120, 122, 124) of the wheel brakes (104, 106, 108, 110) are configured to actuate the respective wheel brakes (104, 106, 108, 110) based on second operating information of the brake operating unit (112) received via the second data connection (156).
本发明涉及一种用于机动车辆的制动系统(100),该制动系统具有机电式车轮制动器(104,106,108,110)、制动器操作单元(112)和中央制动器控制单元(102),其中,这些车轮制动器(104,106,108,110)分别具有本地制动器控制单元(118,120,122,124)。该中央制动器控制单元(102)经由第一数据连接(154)直接连接到制动器操作单元(112)以及这些车轮制动器(104,106,108,110)的本地制动器控制单元(118,120,122,124),而该制动器操作单元(112)经由第二数据连接(156)直接连接到至少一个车轮制动器(104,106,108,110)的本地制动器控制单元(118,120,122,124)。在该制动系统(100)的正常操作模式下,该中央制动器控制单元(102)被配置为根据尤其是经由该第一数据连接(154)接收的该制动器操作单元(112)的第一操作信息来确定至少一个制动需求,并将与该制动需求相对应的控制信号传输到这些车轮制动器(104,106,108,110)的本地制动器控制单元(118,120,122,124)。在该制动系统(100)的后备液位操作模式下,这些车轮制动器(104,106,108,110)的本地制动器控制单元(118,120,122,124)被配置为基于经由该第二数据连接(156)接收的该制动器操作单元(112)的第二操作信息来驱控相应的车轮制动器(104,106,108,110)。
