Abstract:
1. A split series-parallel hybrid dual-power drive system operable alternatively as a series power drive system or a parallel power drive system, comprising: a first drive system for driving a first load, the first drive system including an engine and a first dynamo-electric unit, the engine having a rotary part coupled to the first dynamo-electric unit directly or through a first transmission unit and coupled to the first load directly or through a second transmission unit; a second drive system for driving a second load, the second drive system including a second dynamo-electric unit, the second load being coupled to the second dynamo-electric unit directly or through the first transmission unit or through at least one of a fourth clutch and a fourth transmission unit; a control interface for receiving at least one of a manual input and an input of a control signal to control the operation of the system; a redundant rechargeable device controlled by a start switch to drive a starter motor that is coupled to the engine; a second clutch provided between and coupled to the engine and the first dynamo-electric unit; a drive control unit for controlling the first drive system, the second drive system, and the second clutches; and wherein when the system operates as the series power drive system, a portion of a rotational kinetic energy from the engine drives the first load through a transmission unit, another portion of the rotational kinetic energy from the engine drives the first dynamo-electric unit to operate as a generator, and power from the first dynamo-electric unit drives the second dynamo-electric unit through a control unit to function as a motor for driving the second load.
