    摘要: The controller includes motor control means for controlling the drive RPM of a motor generator to reach a specified RPM less than the idle RPM when the braking condition of a foot brake is detected by a brake-operating-state detecting means while a motor generator is being rotated at an idle RPM or more. This reduces uncomfortable shock which tends to occur because of a change in the rotation of the motor during braking as much as possible to improve drive feeling.

    摘要: A shift control apparatus controlling a stepped transmission. The apparatus is configured with a gear ratio setting unit, and a shift speed change determining unit. A shift speed change predicting unit predicts in advance a change of shift speed by the shift speed change determining unit based on the set gear ratio, a rate of change in the set gear ratio, and an engagement preparation time which is a time needed for engagement preparation of the friction engagement element. A shift control unit controls a hydraulic actuator so that engagement preparation of a friction engagement element to be engaged is performed when a change of shift speed is predicted, and controls the hydraulic actuator so that a hydraulic pressure needed for engaging the friction engagement element is supplied to a hydraulic servo when a change of shift speed is determined by the shift speed change determining unit.

    摘要: When the shift stage of a transmission is not being changed, a change gear ratio Gr of a transmission is calculated by setting an inputted rotation speed Nm2 as a control rotation speed Nm2*, and when the shift stage of the transmission is being changed, the change gear ratio Gr is calculated by setting the rotation speed that is obtained by adding a value obtained by multiplying a difference ΔNm2, which corresponds to the time differential component of the rotation speed Nm2, by a gain km to the rotation speed Nm2 (S130 to S160). By using these, torque commands Tm1* and Tm2* of motors MG1 and MG2 are set so that the engine is operated at an operation point represented by a target rotation speed Ne* and a target torque Te*, by which the engine and the motors MG1 and MG2 are controlled.
