1. A drive system for a vehicle, comprising:
a first electromagnetic device directly coupled to a first planetary gear set; and
a second electromagnetic device directly coupled to a second planetary gear set;
wherein:
the first planetary gear set is directly coupled to a primary mover of the vehicle via a connecting shaft;
the first planetary gear set and the second planetary gear set are radially aligned with the connecting shaft;
in a first mode of operation, a clutch is engaged to couple the second planetary gear set to the first planetary gear set and a brake is disengaged to allow rotation of the second planetary gear set;
in a second mode of operation, the brake is engaged to limit rotation of the second planetary gear set and the clutch is disengaged; and
in a third mode of operation, both the clutch and the brake are disengaged such that the connecting shaft is driven by the primary mover without providing output power to tractive elements of the vehicle.
