Abstract
A vehicle includes an engine, a drive axle, a multi-mode transmission, and a controller coupled to the multi-mode transmission. The multi-mode transmission includes a first gear set having a first planetary gear carrier and a second gear set having a second planetary gear carrier, the first planetary gear carrier and the second planetary gear carrier being rotatably coupled, a first motor/generator coupled to the first gear set, a second motor/generator coupled to the second gear set and selectively coupled to the engine, a brake positioned to selectively limit a rotational movement of a ring gear of the second gear set when engaged, a first clutch, and a second clutch. The controller is configured to engage the second clutch, the brake, and the first clutch to selectively reconfigure the multi-mode transmission to an intermediate shift mode of operation.
