Abstract:
1. A hybrid powertrain comprising: an engine having a crankshaft; a motor/generator; a belt drive train operatively connectable to the crankshaft and to the motor/generator for establishing a driving connection therebetween; a gear train operatively connected to the crankshaft separately from the belt drive train; a starter mechanism controllable to selectively establish a driving connection to the crankshaft through the gear train; at least one actuator activatable to establish the driving connection between the engine and the motor/generator via the gear train; a first energy storage device operable within a first range of operating voltage; a first switching device controllable for selectively establishing electrical power flow between the first energy storage device and the motor/generator; wherein no energy storage device is continuously operatively connected to the motor/generator; a control system having at least one electronic controller operatively connected to and controlling the engine, the motor/generator, the starter mechanism, the first switching device, and said at least one actuator; wherein said at least one electronic controller executes a stored algorithm and controls the hybrid powertrain in accordance with the stored algorithm to establish any one of multiple operating modes in at least partial dependence upon at least one of a parameter of the first energy storage device, a parameter of the control system, a parameter of the motor/generator, and a parameter of said at least one actuator.
