    摘要： PROBLEM TO BE SOLVED: To provide a control device that can properly and at an early time, achieve a slip state of a second engagement device, when controlling the second engagement device to the slip state while a first engagement device is under a released state.SOLUTION: There is provided the control device 3 for controlling a drive device 1 wherein the first engagement device CS, a rotary electric machine 12, and the second engagement device C1 are provided in this order on a power transmission path connecting an input member I and an output member O. The control device includes: a loss torque estimation part 47 which derives an estimated loss torque which is an estimated value of a loss torque caused by the drag resistance of the first engagement device CS when the first engagement device CS is in a released state; and a specific slip time hydraulic control part 45b which, when the first engagement device CS is in a released state and a specific slip control is executed to make the second engagement device C1 in a slip state, sets a supply hydraulic pressure to the second engagement device C1 so that a transmission torque capacity of the second engagement device C1 becomes the capacity corresponding to an estimated input torque determined as a difference between the output torque of the rotary electric machine 12 and the estimated loss torque.

    摘要： PROBLEM TO BE SOLVED: To provide a controller for a vehicle driving device having a differential condition change-over device provided with an electric differential part for controlling a differential condition by an electric motor and switching into the differential condition or non-differential condition to prevent the reduction of durability of the differential condition change-over device. SOLUTION: This controller for the vehicle driving device includes a stand-by control means 106 for switching and controlling the differential condition change-over device (CO, BO) into stand-by control based on a switching line diagram provided with a stand-by region where the differential condition change-over device (CO, BO) is put in a condition immediately before starting its engagement between a differential region and a lock region. When the differential condition change-over device (CO, BO) enters the stand-by region from the differential region, this device gets into the condition immediately before starting its engagement. Consequently, the differential condition change-over device (CO, BO) has sufficient torque capacity immediately after engine torque is increased, and the reduction of durability of this device can be prevented.

    摘要翻译： 要解决的问题：提供一种具有差动状态转换装置的车辆驱动装置的控制装置，该差速条件转换装置设置有用于通过电动机控制差动状态的电动差速部件并切换到差动状态或非差动 条件以防止差动状态转换装置的耐久性降低。 解决方案：用于车辆驱动装置的该控制器包括一个备用控制装置106，用于根据设有一个开关线图的开关线图将差分状态转换装置（CO，BO）切换和控制为待机控制 备用区域，其中差分条件转换装置（CO，BO）处于紧接着在差动区域和锁定区域之间的接合之前的状态。 当差分条件转换装置（CO，BO）从差分区域进入待机区域时，该装置在开始接合之前立即进入状态。 因此，差速条件转换装置（CO，BO）在发动机扭矩增加后立即具有足够的扭矩容量，并且可以防止该装置的耐用性的降低。 版权所有（C）2008，JPO＆INPIT
