用于混合动力传动系的加速方法
本发明涉及一种用于混合动力传动系(1)的加速方法，其中，该加速方法至少包括按以下顺序进行的以下步骤：a.当在所述传动装置输出轴(4)处存在中等扭矩请求并且在带驱动传动装置(2)上设定较低传动比(5)时，接收加速指令，并且通过所述第一断开式离合器(11)中断内燃发动机(7)与电机(9)之间的扭矩传输；b.使较低传动比(5)以调节梯度(12)朝向较高传动比(6)转换并且使转子轴(10)的转子速度增大；以及c.在步骤b.启动之后，使第一断开式离合器(11)接合以启动ICE轴(8)并且使ICE轴(8)的旋转速度朝向当前转子速度增大。在此提出的加速方法允许在高效使用动力系而没有高功率消耗的情况下使混合动力传动系快速加速。
An acceleration method for a hybrid drivetrain includes providing the hybrid drivetrain, setting an initial torque transmission ratio of a belt-drive transmission to a lower transmission ratio, and opening a first disconnect clutch to interrupt torque transmission between an internal combustion engine and an electric machine. The method also includes receiving an acceleration command, shifting the torque transmission ratio with a transmission adjustment gradient from the lower transmission ratio towards an upper transmission ratio, increasing a rotor speed of a rotor shaft of the electric machine with a rotor shaft adjustment gradient, and engaging a first disconnect clutch to rotate an ICE shaft to start the internal combustion engine and increase a rotational speed of the ICE shaft towards a current rotor speed.
