Control apparatus for controlling driving device of vehicle
First Claim
1. A control apparatus for controlling a driving device of a vehicle, the driving device including a transmission system including (A) a non-step speed change portion which includes (a1) a differential device including a first rotary element connected to an engine, a second rotary element connected to a first electric motor, and a third rotary element connected to a transmission member, and (a2) a second electric motor provided in a power transmission path between the transmission member and a plurality of drive wheels, and which functions as an electric, continuously variable transmission, and (B) a stepwise speed change portion which constitutes a portion of the power transmission path and functions as a stepwise automatic transmission, the control apparatus comprising:
- a differential-state switching device which is associated with the differential device and selectively switches the differential device to a differential state thereof in which the non-step speed change portion can operate as the electric continuously variable transmission, and to a non-differential state thereof in which the non-step speed change portion cannot operate as the electric continuously variable transmission; and
a rotation speed synchronization controller which, when a stepwise speed change control of the transmission system is performed, performs, with at least one of the first and second electric motors, a synchronization control of respective rotation speeds of the first, second, and third rotary elements, to respective rotation speeds thereof after completion of the stepwise speed change control.
