The invention relates to a driving power system for a vehicle having wheels (R1-R4), comprising: a main control unit (M-ECU) for detecting and/or generating steering and braking commands; at least two hydraulically actuatable wheel brakes (RB1-RB4), each wheel brake being associated with a respective one of the wheels (R1-R4); at least one electric traction motor having a traction motor control unit, the traction motors (TM1, TM2) for driving at least one of the wheels (R1-R4), the main control unit being communicatively connected to the traction motor control unit for controlling the traction motors (TM1, TM2) to execute steering and braking commands; the invention relates to a driving power system, in particular a main control unit (M-ECU), comprising at least one (first) electro-hydraulic pressure supply unit (BM1), in which a brake pressure control valve in the form of a dedicated solenoid valve (MV2k), which valve can be closed in particular, and one of the outlet valves (AV1-AV4) are associated with at least one hydraulically actuatable wheel brake (RB1-RB4), in which the driving power system, in particular the main control unit (M-ECU), is connected to at least one (first) electro-hydraulic pressure supply unit (BM1). And a dedicated solenoid valve (MV2k) configured to selectively release pressure in the at least one hydraulically actuatable wheel brake by means of the associated outlet valve or by means of the dedicated solenoid valve (MV2k).
本发明涉及一种用于具有车轮(R1‑R4)的车辆的行驶动力系统,包括:用于检测和/或生成转向命令及制动命令的主控制单元(M‑ECU);至少两个可液压致动的车轮制动器(RB1‑RB4),其中,每个车轮制动器分别与车轮(R1‑R4)中的一个车轮相关联;至少一个具有牵引电机控制单元的电牵引电机,其中,牵引电机(TM1、TM2)用于驱动车轮(R1‑R4)中的至少一个车轮,主控制单元与牵引电机控制单元通信连接,以控制牵引电机(TM1、TM2)来执行转向命令和制动命令;以及至少一个(第一)电液压力供应单元(BM1),其中,一种专用电磁阀(MV2k)形式的制动压力调节阀(该阀尤其能够紧闭)以及出口阀(AV1‑AV4)中的一个出口阀与至少一个可液压致动的车轮制动器(RB1‑RB4)相关联,其中,该行驶动力系统,尤其是主控制单元(M‑ECU),被配置为能够通过相关联的出口阀或者通过专用电磁阀(MV2k)有选择性地释放至少一个可液压致动的车轮制动器中的压力。
