摘要： PROBLEM TO BE SOLVED: To provide a control device of an automatic transmission for a vehicle for restraining the occurrence of a shock while improving shift responsiveness.SOLUTION: In a down-shift of the automatic transmission 20 in a state of stepping an accelerator, any of a clutch-to-clutch shift for advancing the shift by gradually reducing engaging pressure of a clutch C or a brake B released by the shift and a rotational synchronous shift for advancing the shift by reducing the engaging pressure of the clutch C or the brake B quicker than in the clutch-to-clutch shift, is selected based on output shaft torque Tof the automatic transmission 20. Since an area of selecting the rotational synchronous shift is set on the lower side of the output shaft torque than an area of selecting the clutch-to-clutch shift, a shift of laying stress on a shift speed and a shift of laying stress on a shift shock can be properly and selectively performed in response to the output shaft torque T.

摘要： PROBLEM TO BE SOLVED: To improve drivability when shifting a transmission part, in a vehicle power transmission device including an electric differential part and the transmission part. SOLUTION: In engine load mode or motoring mode, where a first electric motor M1 is torque-controlled with an engine speed N E (an engine operating point) as a target value, a second electric motor M2 is torque-controlled such that fluctuation of an input torque of the automatic transmission part 20 is suppressed. In the automatic transmission part 20, coast-downshifting is likely to proceed later than in autonomous state or engine stop state where the first electric motor M1 is not torque-controlled, while an engagement-side engagement pressure during coast-downshifting of the automatic transmission part 20 is increased, thereby securing the same transmission progress (transmission responsiveness) as that in the engine stop state or autonomous state.

摘要： PROBLEM TO BE SOLVED: To provide a controller for suppressing influence of a difference in a vehicle speed to improve driving force responsiveness, in a vehicular power transmission device having electric motors connected to an engine. SOLUTION: When a charging restriction decision means 96 decides that required engine output P ER cannot be generated in the engine 8 due to the restriction on generation power of a first electric motor M1, a third electric motor control means 98 executes third electric motor discharge control for generating third electric motor torque T M3 under another condition. Accordingly, even at a low vehicle speed, i.e., even when power consumption of a second electric motor M2 is low, the third electric motor M3 functions as a motor, so that the power generated by the first electric motor M1 is consumed, and the restriction on the generation power of the first electric motor M1 is relaxed or eliminated. Thereby, the power generated by the first electric motor M1 is prevented from being largely restricted by the vehicle speed, and the required engine output P ER can be generated in the engine 8 to improve the driving force responsiveness.

摘要： PROBLEM TO BE SOLVED: To provide a control device, restraining a durability decrease of a differential part and its related parts by preventing a rotating element of the differential part from reaching a high-speed rotation in a vehicular power transmitting apparatus including the differential part. SOLUTION: A rotation stop determining means 72 makes a query as to whether a first rotary element RE1 is lowered in a rotation speed to be stopped during an engine drive mode. If the answer is YES and a differential-portion rotation speed determining means 74 makes a positive determination, then engaging-element control-executing means 78 executes engaging element control. This allows a third rotary element RE3 of the differential portion 11, connected to drive wheels 38 via an engaging element of an automatic shifting portion 20, to approach a state available to freewheel. This prevents a secondary rotary element RE2 and a first electric motor M1 from reaching high-speed rotations caused by a decrease in rotation speed of the first rotary element RE1 in a stop direction and a differential action of the differential portion 11. This enables the prevention of a durability decrease of a power distributing mechanism 16 and the first electric motor M1. COPYRIGHT: (C)2009,JPO&INPIT
