    Abstract: PROBLEM TO BE SOLVED: To improve a feeling of operation in down-shift regardless of the input restriction of an electricity accumulating device. SOLUTION: When a shift position SP is changed from a D position to an S position, or down-shift is performed at the S position (S160), braking side torque is made to act on a driving shaft by the motoring of an engine by a first motor and a second motor, and request torque Tr* is output within the range of input/output restriction Win and Wout of a battery (S220 to S280), and torque which can not be output from the second motor since it exceeds the input restriction Win of the battery among the request torque Tr* is output to the driving shaft by a hydraulic brake for traveling (S290). Thus, it is possible to output torque Td (T) for down-shift giving a feeling of operation similar to shift feeling in a type of motor vehicle equipped with a stepped automatic shift to a driver (S170 to S210), and to improve the feeling of operation in down-shift regardless of input restriction Win.

    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 perform control considering drive requirement of a driver, in a vehicle having a motor that can output power to an axle shaft. SOLUTION: When a torque exceeding a predetermined value is outputted from a motor for a predetermined time while a vehicle is in a stop state while outputting a corresponding torque based on the opening of an accelerator Acc, the torque from the motor 22 is reduced with a torque reduction ratio Rd2 to move the vehicle backward (Steps S300-S410). When the phase where the motor current is concentrated is switched (Step S330), a torque command Tm2* is set so as to increase the torque from the motor MG2 with the torque increase ratio Ri set based on the opening of the accelerator Acc in the stop state and an estimated gradient value θ (Steps S450-S470, S390-S410).

    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

    解决方案：当加速器关闭或加速踏板稍微踩踏时，将Lo-Hi换档中的马达MG2的转矩传递到驱动轴的变速器的齿轮级移动时，发动机在 高于怠速转速Nid1的转速的转速最小转速Nchg（S150，S200）。 因此，发动机可以快速地从发动机输出大的扭矩，并且可以通过作为驱动轴的环形齿轮轴32a快速输出大的动力。 由于电动机MG1的转速Nm1可能降低，所以电动机MG1可以减小电池的充放电功率。 结果，可以抑制由于电池的过剩电力引起的充电和放电。 版权所有（C）2007，JPO＆INPIT
