摘要：
A powertrain includes an electro-mechanical transmission mechanically-operatively coupled to an internal combustion engine and first and second electric machines adapted to selectively transmit mechanical power to an output member. An apparatus for controlling the powertrain includes the first and second electric machines, a first electric machine cooling circuit directing a cooling hydraulic flow to the first electric machine, a second electric machine cooling circuit directing a cooling hydraulic flow to the second electric machine, a hydraulic control system receiving a hydraulic flow and selectively channeling the hydraulic flow to the first and second electric machine cooling circuits, and an active electric machine cooling control system monitoring temperatures of the first and second electric machines, monitoring operation of the hydraulic control system, and selectively controlling the hydraulic control system.
