    • A drive system has an electrically controlled differential portion (11) in which a differential state between an input-shaft rotation speed and an output-shaft rotation speed is controlled upon controlling a first electric motor (M1), and a shifting portion (20) and a second electric motor (M2) disposed in a power transmitting path between the electrically controlled differential portion and drive wheels (34). In a control device for controlling the drive system, a rotation direction of an output shaft (18) of the shifting portion is able to be determined without increasing the number of component parts such as a rotation speed sensor. The control device includes rotation direction determination means (86) for determining a rotation direction of an output shaft (22) of an automatic shifting portion (20) based on an engagement of a given coupling element and a detected result of rotation direction detection means (92). This enables the rotation direction of the output shaft 22 of the automatic shifting portion (20) to be suitably detected without increasing the number of component parts such as the rotation speed sensor.
    • 驱动系统具有电控差动部(11),其中通过控制第一电动机(M 1)来控制输入轴转速与输出轴转速之间的差动状态,以及变速部(20) )和设置在电气控制差速部分和驱动轮(34)之间的动力传递路径中的第二电动机(M 2)。 在用于控制驱动系统的控制装置中,能够确定变速部分的输出轴(18)的旋转方向,而不增加诸如转速传感器的部件的数量。 控制装置包括旋转方向确定装置(86),用于基于给定的联接元件的接合和旋转方向检测装置的检测结果确定自动变速部分(20)的输出轴(22)的旋转方向(86) 92)。 这样可以适当地检测自动变速部分(20)的输出轴22的旋转方向,而不增加旋转速度传感器等部件的数量。
