To provide a vehicular driving device equipped with a torque distributor that controls torque distribution ratios of front and rear wheels, which can switch a two-wheel driving mode to a four-wheel driving mode, while preventing switching of the two-wheel driving mode to the four-wheel driving mode from being complicated.SOLUTION: In switching an EV travelling mode which is a two-wheel driving mode to a four-wheel driving mode, an electronic control device 130 switches a transfer 28 to a power source separation four-wheel driving mode, when the power source separation four-wheel driving mode can be set, which can control torque distribution ratios Rx to front wheels 14 and to rear wheels 16 to required torque distribution ratios Rxdem so that the EV travelling mode can be switched to the four-wheel driving mode of driving the front wheels 14 and the rear wheels 16, while preventing switching of the EV travelling mode of driving the front wheels 14 to the four-wheel driving mode from being complicated.SELECTED DRAWING: Figure 1 【課題】前後輪のトルク分配比を制御するトルク分配装置を備える車両用駆動装置において、二輪駆動モードから四輪駆動モードへの切替が複雑になることを抑制しつつ、四輪駆動モードへの切替が可能になる車両用駆動装置を提供する。【解決手段】電子制御装置１３０は、二輪駆動モードであるＥＶ走行モードから四輪駆動モードへ切り替えるに当たり、動力源分離四輪駆動モードが設定可能であるときにはトランスファ２８を動力源分離四輪駆動モードに切り替えるため、前輪１４を駆動するＥＶ走行モードからの複雑な切り替えを抑えつつ、前輪１４及び後輪１６へのトルク分配比Ｒxを要求トルク分配比Ｒxdemに制御して前輪１４及び後輪１６を駆動する四輪駆動モードに切り替えることができる。【選択図】図１
