Patent ID: 7654933

Claim:
A split serial-parallel hybrid dual power drive system, comprising: a first drive system ( 1001 ), including: an active rotational power source ( 100 ); a first dynamo-electrical unit ( 101 ) configured to be driven by said active rotational power source; at least one first load; a first transmission configured to transmit rotational kinetic energy to said at least one first load; and at least one first clutch ( 112 ) configured to selectively transmit rotational kinetic energy between said first dynamo-electrical unit and said first transmission; and a second drive system ( 1002 ), including: at least one second load; a single second transmission configured to drive each at least one second load; and at least one second dynamo-electrical unit ( 103 ) configured to drive at least one second load; and a second clutch ( 132 ) configured to selectively transmit rotational kinetic energy between said active rotational power source and said second drive system, wherein each said at least one second load is configured to be selectively driven directly either by said second transmission or by a respective said second dynamo-electrical unit.
