A control device according to the invention for operating a road-coupled hybrid vehicle is provided with at least one electronic control unit, a first drive unit associated with a main axle and a second drive unit associated with a secondary axle. The drive unit of the main axle has at least one internal combustion engine and an automatic transmission. The drive unit of the secondary axle has at least one electric drive motor. The control unit is designed to receive, as input variables, a predetermined total target creeping moment and a command for switching from a single-axle operation to a dual-axle operation with a predetermined all-wheel factor. The control unit then sets a predetermined target torque for the internal combustion engine of the main axle according to the all-wheel factor. The control unit also detects the actual clutch torque of the transmission thus generated. If a functional module of the control unit determines a difference between an actual clutch torque and a total target creep torque, the functional module presets a corresponding target torque for an electric drive motor of the secondary axle in order to compensate for the difference.
根据本发明的用于运行道路耦合的混合动力车辆的控制装置配备有至少一个电子控制单元、配设给主车桥的第一驱动单元和配设给副车桥的第二驱动单元。主车桥的驱动单元具有至少一个内燃机和自动变速器。副车桥的驱动单元具有至少一个电驱动马达。所述控制单元被设计为接收预设的总目标蠕行力矩和用于以预设的全轮因子从单车桥运行切换到双车桥运行的命令作为输入变量。然后,控制单元根据全轮因子为主车桥的内燃机调设预设的目标扭矩。所述控制单元还检测变速器的由此产生的实际离合器力矩。如果所述控制单元的功能模块确定了实际离合器力矩与总目标蠕行力矩之间的差值,则该功能模块为副车桥的电驱动马达预设相应的目标扭矩,以补偿所述差值。
