Abstract: PROBLEM TO BE SOLVED: To more effectively suppress vibration of a vehicle that may be generated when starting an internal combustion engine in traveling using an electric travel priority mode.SOLUTION: When the temperature Tw of engine cooling water is under the threshold Tref which is beforehand determined within temperature range required for warm up when starting the engine into operation during travel in an electric travel priority mode, the drive control of the motor MG 2 is carried out by setting a large control gain kv and a large limit torque Tlim, compared with the normal start time (S880, S890), setting a vibration damping torque Tv by the control gain kv and the limit torque Tlim (S900, S910), and correcting the motor torque command Tm2* by the vibration damping torque Tv. Thereby vibration of the vehicle which may be generated when starting the engine can be suppressed, and giving drivers and occupants displeasure and sense of incongruity by vibration of the vehicle can be suppressed.

Abstract: PROBLEM TO BE SOLVED: To restrain sudden change of driving force to a driving shaft based on torque limitation in a lock range of a power generator in a power output device including a 3-axis power input/output device such as a planetary gear mechanism in which three rotational elements are connected to the driving shaft, an output shaft of an internal combustion engine and a rotary shaft of the power generator. SOLUTION: In the lock range in which the absolute value of a motor rotational frequency Nm1 is under a value N1, torque based on an inverter cooling water temperature Tinv is coded to set torque limitation, in an ordinary range in which the absolute value of the motor rotational frequency Nm1 is equal to or more than a value N2, rated maximum torque Tmax is coded to set torque limitation, and in a transition range in which the absolute value of the motor rotational frequency Nm1 is equal to or more than N1 and under the value N2, torque smoothly connecting the torque of the lock range and the rated maximum torque Tmax to a change in the motor rotational frequency Nm1 is set as torque limitation. Thus, even if the motor rotational frequency Nm1 suddenly changes extending between the value N1 and the value N2, a sudden change in torque to the driving shaft can be restrained.

Abstract: PROBLEM TO BE SOLVED: To suppress output of excessive power from a plurality of secondary batteries of a battery apparatus, and to prevent a motor control unit from setting a target second battery apparatus power again without using a target second battery apparatus power received from a main control unit. SOLUTION: A motor ECU controls a motor, in a range where estimated power consumption Pm2* is equal to or less than the full connection power output limit Woutco (S610 to S614). When a power given by subtracting a target slave-side power Pbs* received through communication from an estimated power consumption Pm2* is equal to or less than a corrected power output limit Wout1mo (Wout+ΔW), the motor ECU controls a boost circuit by using the received target slave-side power Pbs* (S650, S660, S662); and when the power (Pm2*-Pbs*) is larger than the corrected power output limit Wout1mo, the motor ECU sets the power (Pm2*-Wout1mo) to the target slave-side power Pbs* again to control the boost circuit (S650 to S662).
