    • A drive unit for a motor vehicle having a hybrid drive, includes an internal-combustion engine, an electrical rotating machine with a pertaining energy accumulator, a transmission unit, and a control unit. The transmission unit includes at least one starting gear position which can be operated only and exclusively when defined conditions exist during a starting operation from the stationary position of the vehicle. For this purpose, the control unit is constructed such that, as a function of the charge condition of the energy accumulator, the starting operation takes place in a standard gear position of the first ratio, or the starting operation takes place in the starting gear position with a ratio of the transmission unit different from the first ratio.
    • 具有混合动力驱动的机动车辆的驱动单元包括内燃机,带有相关蓄能器的旋转电机,传动单元和控制单元。 变速器单元包括至少一个起动档位,该起动档位只有在来自车辆的静止位置的起动操作期间存在限定条件时才可以被操作。 为此,控制单元被构造成使得根据能量蓄能器的充电状态的函数,启动操作在第一比例的标准档位中进行,或者起动操作发生在起动档位 传动单元的比率与第一比率不同。
