Abstract: PROBLEM TO BE SOLVED: To select an electric-motor reversing mode or a transmission reversing mode to obtain a proper drive force at the reversing of a vehicle.SOLUTION: When a transfer (T/F) is in a Hi-range (small reduction ratio) and the number of revolutions of a second motor generator MG2 does not become large at the reversing, an electric-motor reverse is selected and startability is improved by securing the drive force necessary for the reversing start. On the other hand, when the transfer is in a Lo-range (when the reduction ratio is large) and the number of revolutions of the second motor generator MG2 become large, the transmission reverse is selected to obtain a large drive force at the acceleration of a vehicle speed by the power of an engine or the like, and thus traveling performance is improved.

Abstract: PROBLEM TO BE SOLVED: To reduce shock in switching of a driving power source from a second driving power source to a first driving power source (or in switching from regeneration by a motor to engine driving) in a controller for a vehicle driving device having an engine and a motor as the driving power sources and a transmission part for improving drivability. SOLUTION: When the driving force source is switched from a second electric motor MG2 to the engine 10 due to increase in a vehicle velocity, for example, first of all a gear ratio of a continuously variable transmission part 30 is changed to that (a high gear ratio) matching the engine 10, and after changing the gear ratio, the engine 10 is started. In this way, shock in switching is reduced. Furthermore, drivability can be improved by securing driving torque when torque of the second electric motor MG2 is temporarily increased according to the gear ratio of the continuously variable transmission part 30 during transition of the switching.

Abstract: PROBLEM TO BE SOLVED: To improve response to engine start, in a controller for a vehicle driving device provided with an engine, an electric motor, and a transmission. SOLUTION: A controller for a vehicle driving device increases a shift speed so that shift of the continuously variable transmission part 30 is quickly completed when the start of the engine is requested, and ignites the engine 10 after the completion of the shift of the continuously variable transmission part 30 (or after the shift speed at the final stage of the shift decreases below a predetermined value). By performing such speed change control, delay in the engine start is minimized, and thus, for example, delay in generation of output torque with respect to stepping-on of an accelerator pedal is reduced.
