Abstract
A hybrid powertrain system includes reciprocating free-piston internal combustion engines, each including a linear alternator device configured to generate electric power. A control module determines mechanical and electrical power demands responsive to an operator torque request and a state of charge of an energy storage device. The control module operates the torque machine to generate an output torque responsive to the mechanical power demands and operates the reciprocating free-piston internal combustion engines to generate electric power responsive to the electrical power demands.
