摘要： PROBLEM TO BE SOLVED: To provide a power transmission for vehicles which suppresses the occurrence of relatively sudden variation of the output shaft torque of a power transmission caused when the output rotational speed of an electric differential unit varies. SOLUTION: When the output rotational speed N 18 of a differential unit 11 varies, the deviation value e of the actual rotational speed N E of an engine 8 from a target rotational speed N ELINE is calculated at a predetermined time. The target rotational speed N ELINE is set so that the deviation value e may converge with a predetermined slope. Therefore, in controlling the engine rotational speed by means of, e.g., an electric motor M1, the variation of the output shaft rotational speed of the differential unit 11 can be preferably reduced. Hence, the power transmission 10 can be provided which enables suppression of the occurrence of relatively sudden variation of the output shaft torque caused when the output rotational speed of the differential unit 11 varies.

摘要： PROBLEM TO BE SOLVED: To improve drivability at gear shifting of a transmission section, in a vehicle power transmission device including an electric differential section and the transmission section. SOLUTION: When M1 inertia cancel control is performed at gear shifting of an automatic transmission section 20, a predetermined inertia cancel torque Ti M1 output as a part of M1 torque T M1 during the M1 inertia cancel control is changed based on the vehicle state by a cancel torque changing means 92. Therefore, uniform M1 inertia cancel control is not attained for suppressing change in engine rotation during the gear shifting of the automatic transmission section 20, and the M1 inertia cancel control can be performed according to the vehicle state. For example, the engine rotation speed N E can be changed according to the vehicle state during the gear shifting of the automatic transmission section 20. Therefore, the drivability can be improved during the gear shifting of the automatic transmission section 20. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To concurrently improve fuel economy, ensure responsiveness during garage shift, and miniaturize an electric oil pump in a vehicle power transmission capable of switching a power transmission state and a power transmission cut-off state by engaging and releasing a hydraulic engagement device based on an operation of a switching device capable of selectively switching a driving position and a non-driving position.
SOLUTION: An electric oil pump 106 previously supplies hydraulic pressure while keeping a power transmission cut-off state to a predetermined hydraulic engagement device engaged for switching to a power transmission state during garage shift in a non-driving position by a pre garage shift control means 92, so that oil supply quantity (oil pressure supply quantity) necessary for engaging the predetermined hydraulic engagement device during the garage shift can be reduced and the responsiveness during the garage shift can be easily ensured. Also, a load of the electric oil pump 106 during the garage shift can be reduced, and output from a motor 104 for the electric oil pump can be lowered.
