    Abstract: PROBLEM TO BE SOLVED: To suppress unexpected variations in the torque of a driving shaft, while outputting more appropriate torque from a motor when changing gear change ratio of a transmission and also outputting the torque from the motor which is equipped with the motor which outputs power to a driving shaft via the transmission. SOLUTION: When the transmission is not under gear change, its gear change ratio Gr is calculated assuming that input rotation speed Nm2 is the rotation speed for control Nm2*; and when it is under gear change, its gear change ratio Gr is calculated by assuming that the deviation ΔNm2, corresponding to a time-derivative component of the rotation speed Nm2 multiplied by a gain km and added to the rotation speed Nm2 as the rotation speed for control Nm2* (S130-S160). Torque instructions Tm1* and Tm2* of motors MG1 and MG2 are set by using these so that the engine is operated by an operation point, represented by a target rotation speed Ne* and a target torque Te* and the engine, and the motors MG1 and MG2 are controlled.

    Abstract: PROBLEM TO BE SOLVED: To make it possible to start an internal combustion engine into operation, even if it is attempted to start the internal combustion engine, by cranking within the range of output restriction of a secondary battery in cold and failed to start. SOLUTION: If it is attempted to start the engine into operation in colds but cannot start, the engine is started by clanking by outputting from the motor MG1, the torque restricted by the torque restriction Tm1max set as the torque larger than the torque required to rotate the engine at least starting minimum rotation speed Nref in the colds based on output limitation Wout of a battery at that time, irrespective of the battery voltage Vb turning into under the lower limit voltage Vmin (S240-S320). As a result, the engine can be started into operation, even if starting of the engine fails in cold periods. COPYRIGHT: (C)2009,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To suppress shock which may be produced by sudden change in the temporal change of output torque from a motor, along with the suppression of sudden change of time change of output torque from the motor. SOLUTION: When the motor MG 1 is controlled by a torque instruction Tm1* which sets an engine to operate at target rotation speed Ne*, and when a temporary torque Tm2tmp calculated so that a demanding torque Tr* might be output to a driving shaft is not in ranges of torque restriction Tm2min and Tm2max based on I/O restriction of battery Win and Wout, restrictions for control Tconmin and Tconmax are set by output torque of the motor MG 2 (last time instruction Tm2*) and torque restriction Tm2min and Tm2max (S200). Thereby the torque instruction Tm2* of the motor MG 2 is set by restricting the temporary torque Tm2tmp (S210). As a result, sudden change of the temporal change of output torque of the motor MG 2 is suppressed, and the shock which may be produced at the time can be suppressed. COPYRIGHT: (C)2009,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To quickly respond to rapid change of a required driving force during the Lo-Hi shift of a gear stage of a transmission. SOLUTION: When shifting a gear stage of a transmission transferring a torque of a motor MG2 to a driving shaft in the Lo-Hi shift while an accelerator is off or an accelerator pedal is slightly stepped on, an engine is operated at or higher than the shift minimum rotation speed Nchg of a rotation speed higher than an idling rotation speed Nidl (S150, S200). Thereby, the engine may quickly output a large torque from the engine and may quickly output large power by means of a ring gear shaft 32a as the driving shaft. Since the rotation speed Nm1 of a motor MG1 may be decreased, the motor MG1 may reduce the power to charge and discharge a battery. As a result, the charge and discharge due to excess electric power of the battery may be suppressed. COPYRIGHT: (C)2007,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To stabilize vehicle speed V during travel at vehicle speed V near maximum vehicle speed and inhibit the deterioration of operation feeling of a driver at that time. SOLUTION: Control vehicle speed Vhis is established with including hysteresis in relation to vehicle speed V (S160-S180) and torque correction value k is established based on control vehicle speed Vhis (S190), execution torque T* is established by correcting demand torque Tr* with using the torque correction value k (S200), and execution torque T* is output of an axle by controlling an engine and two motors, when vehicle speed V is threshold value Vref or higher. Consequently, frequent fluctuation of execution torque T* with accompanying slight increase and decrease of vehicle speed V can be inhibited and vehicle sped V can be stabilized at vehicle speed V near the maximum vehicle speed. As a result, the deterioration of operation feeling of the driver at vehicle speed V near the maximum vehicle speed can be inhibited. COPYRIGHT: (C)2007,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a device for outputting power from a motor via a transmission to a driving shaft, making it possible to change the shift stage of the transmission when impossible to change it with the synchronization of the rotating speed of the motor. SOLUTION: When the shift stage of the transmisision is changed to increase the rotating speed Nm2 of the motor (S300), constant pressure stand-by is performed by using stand-by pressures Pb1, Pb2 of brakes B1, B2 which are set to be greater as the output limit of a battery is smaller (S350) and the rotating speed Nm2 of the motor is increased to a rotating speed Nm2* after changed by the semi-engagement of positive torque of the motor with the brakes B1, B2. Thus, even when the output limit of the battery is smaller to make it impossible to change the shift stage with the synchronization of the rotating speed of the motor before/after changing the shift stage, the semi-engagement with the brakes B1, B2 is used to change the shift stage.
