The invention relates to a method for operating a hybrid vehicle having an electric machine (3), an internal combustion engine (2), a disconnect clutch (4) connected between the internal combustion engine (2) and the electric machine (3), a transmission (5) connected between the electric machine (3) and an output (6) and having a shift element (7), and optionally a hydrodynamic starting element (8) connected between the electric machine (3) and the transmission (5), the clutch (4) is at least partially closed in order to start the internal combustion engine (2) starting from an electric-only drive, in order to pull the internal combustion engine (2) by means of the electric machine (3), and one of the shift elements (7, 10) arranged between the electric machine (3) and the output (6) is slipped, in order to start the internal combustion engine (2) starting from the electric-only drive, and in order to start the internal combustion engine (2) starting from the electric-only drive, the clutch (4) is at least partially closed in order to pull the internal combustion engine (2) by means of the clutch (4). The method is used for slip decoupling. According to whether the starting process of the hybrid vehicle is executed and whether the transmission is transitioned from the torque transmission state to the non-torque transmission state or from the non-torque transmission state to the torque transmission state, the hybrid vehicle is started. And specifying a shift element to be used for slip decoupling and its decoupling differential depending on whether a shift is performed in the transmission and depending on whether the hybrid vehicle has a hydrodynamic starting element.
本发明涉及一种用于运行混合动力车辆的方法,所述混合动力车辆具有电机(3)、内燃机(2)、连接在内燃机(2)和电机(3)之间的分离离合器(4)、连接在电机(3)和输出端(6)之间且具有切换元件(7)的变速器(5)和可选的连接在电机(3)和变速器(5)之间的液力起动元件(8),该液力起动元件具有变矩器(9)和构造为变矩器锁止离合器(10)的另一切换元件,为了从纯电动行驶出发启动内燃机(2),分离离合器(4)至少部分地闭合,以便通过电机(3)牵引内燃机(2),并且使设置在电机(3)和输出端(6)之间的切换元件(7、10)之一进入打滑,以用于打滑解耦。根据是否在执行混合动力车辆的起动过程,并且根据变速器是否从传递扭矩状态转换到非传递扭矩状态或从非传递扭矩状态转换到传递扭矩状态,并且根据是否在变速器中执行换挡并且根据混合动力车辆是否具有液力起动元件来规定要用于打滑解耦的切换元件及其解耦差速。
