Abstract: PROBLEM TO BE SOLVED: To prevent an unexpected driving force from being output when the torque transfer of a transmission is not sufficient and to deal with such a situation more appropriately. SOLUTION: If the high pressure generating system of a hydraulic circuit in the transmission fails and the torque transfer capacity of the transmission is not sufficient, the line pressure of the hydraulic circuit is fixed at low pressure and shifts are inhibited to limit the torque of a motor MG 2 (S160-S180). During a motor-driven mode, the start of the engine is inhibited (S200). During an engine-driven mode, the intermittent operation of the engine is inhibited (S230). In this way, the torque of the motor MG 2 can be transferred within the range of the torque transfer capacity of the transmission and the output of unexpected torque can be avoided at the start of the engine. As a result, a situation in which the torque transfer capacity of the transmission is insufficient can be dealt with more appropriately. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To prevent members of a transmission 60 from wearing, in an automobile 20 in which an engine 22, a motor MG 1 and a drive shaft 32a are connected to a power distribution integrating mechanism 30 and in which a motor MG 2 is connected to the drive shaft 32a via the transmission 60 so that the speed of the transmission 60 is changed by means of the number of revolutions of the motor MG 2 and the number of revolutions of the drive shaft 32a. SOLUTION: When the number of revolutions of the drive shaft 32a cannot be estimated based on the number of revolutions of the engine 22 and the number of revolutions of the motor MG 1, the transmission 60 is not allowed to change speeds. If the transmission 60 is shifted using the number of revolutions of the drive shaft 32a that is detected by a sensor 36 and the number of revolutions of the motor MG 2 while the number of revolutions of the drive shaft 32a cannot be estimated, in the event of failure of the sensor 36 during the shift and members of the transmission 60 could wear due to the non-smooth shift, because the number of revolutions of the drive shaft 32a cannot be used; in this state, the transmission 60 is not allowed to shift so as to avoid such a trouble.

Abstract: PROBLEM TO BE SOLVED: To properly suppress a change in an output power when changing a transmission ratio of a stepwise shift portion of a power transmission device.SOLUTION: A power transmission device includes a stepwise shift portion with an engaging element engaged by an operating pressure. When a transmission ratio of the stepwise shift portion is changed, a transmission ratio change timing input control for controlling an input torque inputted in the stepwise shift portion is executed so that a change of an output power from the stepwise shift portion becomes zero or almost zero. When a deviation between an actual input torque and a target input torque in input torque control in changing a transmission of the stepwise shift portion is larger than a predetermined deviation, the operating pressure is corrected before the input torque control in changing the transmission ratio.

SOLUTION: In an automobile where an engine, a first motor and a driving shaft are connected to a planetary gear mechanism, and a second motor is connected via a transmission to the driving shaft, when the number of revolutions of the driving shaft cannot be detected during speed change, and an engine revolution deviation ΔNe is a threshold Nref or more (S120, S140, S240), the rotational frequency Nr* for control is set under the consideration of not only the current number of revolutions Ne and the number of revolutions Nm1 of the first motor but also the previous number of revolutions (previous Ne) of the engine and the number of revolutions (previous Nm1) of the first motor (S250). Then, the number of revolutions Nm2* of the second motor after speed change is set by using the number of revolutions Nr* for control and the change gear stage of the transmission is changed according to the synchronization of the number of revolutions Nm2 of the second motor.
