Abstract: A driving force control system for improving energy efficiency under a motor-drive mode. The control system selects the motor-drive mode from a single motor-mode where a vehicle is powered by any one of the rotary devices, and a dual motor-mode where the vehicle is powered by both rotary devices. The driving force control system is configured to select the single-motor mode rather than the dual-motor mode, provided that an increment of an energy consumption to establish the dual-motor mode is larger than a decrement of the energy consumption to be achieved by the dual-moor mode, under a driving condition where a required driving force can be achieved by either the single-motor mode or the dual-motor mode.

Abstract: A hybrid vehicle includes a clutch and a transmission unit configured to be able to switch into a neutral state. The hybrid vehicle is able to transmit power of an engine through any one of a first path through which power is transmitted from the engine to a first MG via a transmission unit and a differential unit and another second path through which power is transmitted from the engine to the first MG. The clutch is provided in the second path, and switches between an engaged state and a released state. The controller controls the engine, the first MG, the transmission unit and the clutch. The controller sets the transmission unit to a non-neutral state, sets the clutch to the engaged state, and then causes the vehicle to travel by using driving force from the first MG and driving force from the second MG.
