The invention relates to a dedicated hybrid drive train (1) of a motor vehicle, having a drive unit (4) consisting of a first electric machine (EM1) and an internal combustion engine (ICE), and a second electric machine (EM2), and a method for controlling the dedicated hybrid drive train, the drive unit (4) can be connected by means of a first disconnect clutch (C1) to a transmission (8) and the second electric machine (EM2) can be connected by means of a second disconnect clutch (C2) to the transmission, which is operatively connected to the drive wheels, and the energy accumulator (17) drives the electric machines (EM1, EM2) and can be charged by having the electric machines as a generator. In order to increase the performance and efficiency of the hybrid drive train (1), the transmission (8) has two thermal transmission stages (11, 12), which can be alternately connected by means of a first disconnect clutch (C1), and an electric transmission stage (9), which can be connected by means of a second disconnect clutch (C2), the hybrid drive train (1) is controlled as a function of a driver torque request, a state of charge of the energy accumulator (17) and a driving speed of the motor vehicle.
本发明涉及一种机动车辆的专用混合动力传动系(1)以及用于控制该专用混合动力传动系的方法,该专用混合动力传动系具有由第一电机(EM1)和内燃发动机(ICE)组成的驱动单元(4)以及第二电机(EM2),其中,驱动单元(4)可以借助于第一断开式离合器(C1)连接至传动装置(8)并且第二电机(EM2)可以借助于第二断开式离合器(C2)连接至传动装置,该传动装置操作性地连接至驱动轮,并且蓄能器(17)驱动电机(EM1、EM2)并且可以通过使电机作为发电机进行充电。为了提高混合动力传动系(1)的性能和效率,传动装置(8)具有可以借助于第一断开式离合器(C1)交替连接的两个热传动级(11、12)和可以借助于第二断开式离合器(C2)连接的电传动级(9),其中,混合动力传动系(1)根据驾驶员扭矩请求、蓄能器(17)的充电状态和机动车辆的行驶速度进行控制。
