    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 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 improve fuel economy and responsiveness of driving force to be outputted to a drive shaft, and to suppress the occurrence of vibration or abnormal noise. SOLUTION: When request torque Tr* to be output to a drive shaft (ring gear shaft), when an accelerator is turned off exceeds a value 0, request torque Tr* is reduced by using a rate value Trt2 which is smaller than a rate value Trt1 (S160). A value calculated by subtracting a correction revolution speed ΔN, based on input/output restrictions Win, Wout of a battery 50 from the revolution speed, corresponding to a shift position SP or a speed V is set as a target revolution speed Ne* of an engine 22 (S170, S180). As a result, it is possible to suppress the discharge power of a battery from exceeding the output restriction Wout, and to suppress the occurrence of abnormal noise, such as, the rattling sounds of a gear, or vibration due to the rapid change of the torque of the drive shaft.

    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.
