Abstract: Presented are electric drive unit (EDU) assemblies with integrated power electronics, methods for making/operating such EDU assemblies, and motor vehicles equipped with such EDU assemblies. An EDU assembly includes an outer housing that mounts to a vehicle body. The EDU outer housing has internal motor and transmission chambers and an external cavity. A traction motor is mounted inside the motor chamber and drives one or more vehicle wheels to thereby propel the vehicle. A gear train is mounted inside the transmission chamber and drivingly connects the traction motor to the vehicle wheels. An integrated power electronics (IPE) unit, which is operable to control the traction motor, includes an IPE outer housing with a housing chassis mounted inside the external cavity, and a main housing mounted on the housing chassis to define therebetween a power electronics (PE) chamber. Multiple integrated circuit (IC) PE modules are mounted inside the PE chamber.

Abstract: A hydraulic assembly includes a pump that is bi-rotationally driven by an output shaft of a transmission or transaxle and a hydraulic circuit that includes a pressure actuated control valve and a plurality of check valves. The check valves are arranged so that, regardless of the direction of rotation of the pump, the suction side of the pump is always in fluid communication with a sump and the pressure side of the pump is always in fluid communication with one of the inlet ports of the spool valve. In one direction of rotation of the pump, pressure in a line is supplied to a control port of a control valve to translate a control element to connect an outlet of the pump to the fluid system of the transmission or transaxle. In the other direction of rotation, no pressure is supplied to the control port and the control element, biased by a spring, connects the other outlet of the pump to the fluid system of the transmission.

Abstract: A two mode automatic transmission for a motor vehicle includes a variable ratio component, a plurality of planetary gear assemblies, a chain drive assembly and a plurality of torque transmitting devices. A first planetary gear assembly is associated with an input shaft, a first clutch and a first brake and provides forward and reverse gears. The variable ratio component is driven by the output of the first planetary gear assembly and drives the second planetary gear assembly. The second planetary gear assembly, which may be either a simple or compound planetary assembly, is associated with a second clutch and a second brake and drives the chain drive assembly. The output of the chain drive assembly drives a third planetary gear assembly which is associated with an output shaft.
