The invention relates to an electronically controlled pneumatic service brake system (1) of a vehicle, comprising a pneumatic connection (16a, 16b) which extends between at least one pneumatic output (17a, 17b) of a brake request signal generating means (FBM) and at least one electro-pneumatic control valve (1C-EPM, 2C-EPM; the invention relates to a pneumatic control system (10) between pneumatic control inputs (18, 19a, 19b, 20) of a pneumatic actuator (20, 20a, 20b, 20c According to the invention, an electronically controlled electropneumatic component (24) is arranged in the pneumatic connection (16a, 16b), said electronically controlled electropneumatic component having at least one control pressure input (25, 26) and at least one control pressure output (27, 28), the control pressure input end is used for controlling the input of primary pneumatic control pressure (SD1, SD2) generated by the brake requirement signal generating device (FBM), and the control pressure output end is used for controlling the output of secondary pneumatic control pressure (SD1 *, SD2 *). The secondary pneumatic control pressure is controlled to be input into a pneumatic control input (18, 19a, 19b, 20) of the at least one electro-pneumatic control valve (1C-EPM, 2C-EPM, TCM). The electronically controlled electro-pneumatic component (24) is designed in such a way that the electronically controlled electro-pneumatic component depends only on the primary pneumatic control pressure (SD1, SD2) or only on the secondary electric control signal (SS *) or not only on the primary pneumatic control pressure (SD1, SD2) and also on the secondary electric control signal (SS *). The secondary pneumatic control pressure (SD1 *, SD2 *) is generated, modulated or formed.
本发明涉及一种车辆的电子控制式气动行车制动系统(1),所述行车制动系统具有气动连接部(16a、16b),所述气动连接部架设在制动要求信号产生器件(FBM)的至少一个气动输出端(17a、17b)与所述至少一个电子气动控制阀(1C‑EPM、2C‑EPM;TCM)的气动控制输入端(18、19a、19b、20)之间。根据本发明,在所述气动连接部(16a、16b)中布置有电子控制式电子气动部件(24),所述电子控制式电子气动部件具有至少一个控制压力输入端(25、26)和至少一个控制压力输出端(27、28),所述控制压力输入端用于控制输入由所述制动要求信号产生器件(FBM)产生的初级气动控制压力(SD1、SD2),所述控制压力输出端用于控制输出次级气动控制压力(SD1*、SD2*),所述次级气动控制压力被控制输入到所述至少一个电子气动控制阀(1C‑EPM、2C‑EPM、TCM)的气动控制输入端(18、19a、19b、20)中。所述电子控制式电子气动部件(24)这样构造,使得所述电子控制式电子气动部件仅根据所述初级气动控制压力(SD1、SD2)或者仅根据次级电控制信号(SS*)或者不仅根据所述初级气动控制压力(SD1、SD2)、还根据所述次级电控制信号(SS*),产生、调制或者形成所述次级气动控制压力(SD1*、SD2*)。
