Abstract: A transmission for a hydraulic hybrid motor vehicle includes a planetary gear train (30) capable of differential operation. The planetary gear train has a first element (32) linked to an internal combustion engine (34), a second element (40) linked to drive wheels (22) of the vehicle, and a third element (36) linked to a hydraulic pump (64). The transmission (1) further includes a hydraulic machine which drives the drive wheels (22) by way of a link between the third element (36) of the planetary gear train (30) and the hydraulic pump (64). This link includes a speed reducer (38, 60) that provides, when the whole of the planetary gear train is rotating at the same speed, a reduction in the speed of rotation of the pump relative to that of the internal combustion engine (34) that is greater than a value of approximately two.

Abstract: The power-transmission device has an input shaft, an output shaft, a gear mechanism, and a motor. The gear mechanism includes a plurality of planetary gear mechanisms and a mode-switching mechanism, and transmits the rotations of the input shaft to the output shaft. The mode-switching mechanism selectively switches the drive-power transmission path of the power-transmission device between a plurality of modes. The motor is connected to the rotating elements of the planetary gear mechanisms. A target-input-torque determination unit determines the target input torque, which is a target value for the torque to be inputted to the power-transmission device. The target-output-torque determination unit determines the target output torque, which is a target value for the torque to be outputted from the power-transmission device. The command-torque determination unit uses the torque balance information to determine torque commands to the motor from the target input torque and the target output torque.

Abstract: Transition is made from a motor single-drive mode to a motor dual-drive mode while there is a margin in torque output from a motor MG2 with respect to rated torque. With this, the torque of the motor MG1 is changed slowly in the motor dual-drive mode, whereby it is possible to suppress the generation of vibration (shock) due to torsion of a damper and to compensate for a shortage of the torque of the motor MG1 due to slow change processing with an increase in torque from the motor MG2. As a result, it is possible to achieve both of reduction of a shock due to the torque of the motor MG1 and output of required torque to a drive shaft.
