The invention relates to a driving power system for a vehicle, comprising: a main control unit (M-ECU) for detecting and/or generating steering and braking commands; a brake system having a first electro-hydraulic pressure supply unit (DV1) and a second electro-hydraulic pressure supply unit (DV2); four hydraulically driven wheel brakes (RB1-RB4) associated with the wheels (R1-R4); an electrically driven brake pressure control valve (EV1-EV4, AV1-AV4, SV1-SV4); and a steering actuator (EPS), in particular an electric motor, for driving at least one axle. Wherein the driving power system is configured to: execute at least one steering command, in particular during normal operation, to actuate the at least one pressure supply unit (DV1, DV2) and the steering actuator (EPS); and/or during normal operation a brake command is executed to at least actuate the second pressure supply unit (DV2) and at least actuate the brake pressure regulating valves (EV1-EV4, AV1-AV4, SV1-SV4), and in a (first) failure situation at least actuate the first pressure supply unit (DV1) and at least actuate the brake pressure regulating valves (EV1-EV4, AV1-AV4, SV1-SV4) for wheel-specific pressure regulation.
本发明涉及一种用于车辆的行驶动力系统,包括:用于检测和/或生成转向命令和制动命令的主控制单元(M‑ECU);具有第一电液压力供给单元(DV1)和第二电液压力供给单元(DV2)的制动系统;分配给车轮(R1‑R4)的四个液压驱动的车轮制动器(RB1‑RB4);电驱动的制动压力调节阀(EV1‑EV4、AV1‑AV4、SV1‑SV4);以及一种,特别是电动的,用于驱动至少一个车轴的转向致动器(EPS)。其中,行驶动力系统用于:执行至少一个转向命令,特别是在正常运行期间,以致动至少一个压力供给单元(DV1、DV2)和转向致动器(EPS);和/或在正常运行期间执行制动命令,以至少致动第二压力供给单元(DV2)和至少致动制动压力调节阀(EV1‑EV4、AV1‑AV4、SV1‑SV4),以及在(第一)故障情况下,至少致动第一压力供给单元(DV1)和至少致动制动压力调节阀(EV1‑EV4、AV1‑AV4、SV1‑SV4)以进行车轮特定压力调节。
