Abstract
A hybrid powertrain has a prime mover with a drive member and a multi-speed transmission with an input member and an output member. A first motor/generator is continuously connected for common rotation with the drive member. A second motor/generator is continuously connected for common rotation with the input member. A damper is connected with the input member, and a damper clutch is selectively engageable to connect the first motor/generator and the drive member for common rotation with the second motor/generator and the input member through the damper. The hybrid powertrain includes a controller operatively connected to the motor/generators and the damper clutch. The controller is configured to establish at least a hybrid series operating mode and a hybrid parallel operating mode.
