    摘要： A vehicle includes an engine, a drive axle, a multi-mode transmission, and a controller. 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, a first motor/generator coupled to the first gear set, a second motor/generator electrically coupled to the first motor/generator and coupled to the second gear set, a brake selectively limiting movement of a portion of the second gear set, and a clutch selectively rotationally coupling the second motor/generator to the engine. The first gear set is coupled to the engine, and the planetary gear carriers are rotatably coupled. The controller is configured to selectively configure the multi-mode transmission into an active neutral startup mode of operation by engaging the clutch and the brake such that at least one of the first motor/generator and the second motor/generator produces a voltage.

    摘要： 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 selectively transition the multi-mode transmission between a mid range mode of operation and a high range mode of operation via an intermediate shift mode of operation.

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, a first motor/generator coupled to the first gear set, a second motor/generator coupled to the second gear set and selectively coupled to a connecting shaft, a brake positioned to selectively limit a rotational movement of a ring gear of the second gear set when engaged, a first clutch selectively rotationally coupling the first gear set and the second gear set to the drive axle when engaged, and a second clutch selectively rotationally coupling the second motor/generator to the connecting shaft when engaged. The controller is configured to engage the brake and the clutches to selectively reconfigure the multi-mode transmission to an intermediate shift mode of operation.
