摘要： A vehicular drive system switchable between a continuously-variable and step-variable shifting states, and a control device for controlling the vehicular drive system so as to reduce a shifting shock of an automatic transmission included in the drive system, which takes place due to an overlap control involving a switching control of the drive system and a shifting control of the automatic transmission.Execution-timing control means 82 is provided to command switching control means 50 and step-variable shifting control means 54 to sequentially execute a switching control by the switching control means to switch transmission mechanism 10 between an electrically established continuously-variable shifting state and a step-variable shifting state, and a shifting control by the step-variable shifting control means to shift an automatic transmission portion 20, even when an overlap control involving the switching control and the shifting control is required, whereby the switching and shifting controls can be rapidly completed. Since the transmission mechanism 10 is not switched during the shifting control of the automatic transmission portion 20, the input speed of the automatic transmission portion 20 will not change due to the switching control, apart from a change of the input speed as a result of the shifting control, making it possible to prevent the complicated shifting control and reduce the consequent shifting shock.

摘要： A vehicular transmission mechanism switchable between a continuously-variable shifting state and a step-variable shifting state, and a control device for controlling an operation of switching of the shifting state of the transmission mechanism so as to reduce its switching shock and improve the durability of coupling devices. The transmission mechanism 10 is switchable between the electrically established continuously-variable shifting state and the step-variable shifting state, by selective releasing and engaging actions of switching clutch C0 and brake B0, which are controlled by switching control means 50. Upon switching to the continuously-variable shifting state by the releasing action of the switching clutch C0 or brake B0 under the control of switching control means 50, first electric motor M1 is controlled by electric motor control means 82 such that a reaction torque is generated by the first electric motor, so that a reaction torque of the switching clutch C0 or brake B0 is adequately replaced by the reaction torque of the first electric motor M1, so as to reduce the switching shock upon switching of the transmission mechanism, and a difference between input and output speeds of the coupling device is reduced with a result of reduction of a load on the coupling device in its partially engaged state, and a consequent improvement in the durability of the coupling device.

摘要： Vehicular drive system which is small-sized and/or improved in its fuel economy. A power distributing mechanism 16, which is provided with a differential-state switching device in the form of a switching clutch C0 and a switching brake B0, is switchable by the switching device between a differential state (continuously-variable shifting state) in which the mechanism is operable as an electrically controlled continuously variable transmission, and a fixed-speed-ratio shifting state in which the mechanism is operable as a transmission having a fixed speed ratio or ratios. The power distributing mechanism 16 is placed in the fixed-speed-ratio shifting state during a high-speed running of the vehicle or a high-speed operation of engine 8, so that the output of the engine 8 is transmitted to drive wheels 38 primarily through a mechanical power transmitting path, whereby fuel economy of the vehicle is improved owing to reduction of a loss of conversion of a mechanical energy into an electric energy. The mechanism 16 is also placed in the fixed-speed-ratio shifting state during a high-output operation of the engine 8, so that the required electric reaction of first electric motor M1 can be reduced, whereby the required size of the first electric motor M1, and the required size of the drive system 10 including the electric motor M1 can be reduced.
