Abstract:
1. A control apparatus for a hybrid vehicle, comprising: a power transmission mechanism that is constituted by one or more of planetary gear units, that transmits a driving force developed in an engine to a drive axle and whose dynamic characteristic is represented in revolution two-degrees-of-freedom system; a first motor/generator that supplies a power to the drive axle via the power transmission mechanism; a second motor/generator that supplies the power at least one of directly and via the power transmission mechanism to the drive axle; a target driving force generating section that calculates a target driving power and a target driving torque from at least one of detected values and estimated values of both of a vehicle speed and an accelerator opening angle; a target engine speed calculating section that calculates a target engine speed from the target driving power; and a target torque calculating section that sets target values of motor torques of the first and second motors/generators and of an engine torque from at least one of revolution speed variation rates of any two revolution elements of the power transmission mechanism and a running resistance torque, the target engine speed, an engine speed, the target driving power, and the target driving torque in such a manner that no excessive lack in the driving torque for the target driving torque occurs and a deviation between the target engine speed and the engine speed is decreased.
