The present invention relates to a selective differential drive for a vehicle. A driving system includes a first driving train and a second driving train, which are connected by a differential assembly. Each driving train includes a motor, an output gear, and a clutch assembly engaging the output gear with each half shaft and releasing the engagement from the half shaft. The differential assembly is formed to connect a first half shaft and a second half shaft and formed to connect and disconnect a first output gear and the first half shaft. The differential assembly includes an actuator for engaging a side gear, a spider gear set, and a differential casing with the first output gear and releasing the engagement from the first output gear. A control system operates the actuator of the differential assembly and/or the clutch assembly to achieve one or more driving modes about each driving shaft. The control system determines a first driving mode and controls the clutch assembly and the differential assembly. Also, the control system controls one or more motors. For example, the driving mode includes torque vectoring, complete locking, single motor, and neutral.

    구동 시스템은 디퍼렌셜 조립체에 의해 결합되는 제1 구동 트레인 및 제2 구동 트레인을 포함한다. 각각의 구동 트레인은 모터, 출력 기어, 및 출력 기어를 각각의 하프샤프트와 맞물리게 하고 그로부터 맞물림해제시키는 클러치 조립체를 포함한다. 디퍼렌셜 조립체는 제1 하프샤프트와 제2 하프샤프트를 결합시키도록, 그리고 제1 출력 기어와 제1 하프샤프트를 연결/연결해제시키도록 구성된다. 디퍼렌셜 조립체는, 예를 들어, 사이드 기어, 스파이더 기어세트, 및 디퍼렌셜 케이싱을 제1 출력 기어와 맞물리게 하고 그로부터 맞물림해제시키기 위한 액추에이터를 포함한다. 제어 시스템은 각각의 구동 축에 대한 하나 이상의 구동 모드를 달성하기 위해 클러치 조립체 및/또는 디퍼렌셜 조립체의 액추에이터를 작동시키도록 구성된다. 제어 시스템은 제1 구동 모드를 결정하고, 클러치 조립체 및 디퍼렌셜 조립체를 제어하며, 하나 이상의 모터를 제어한다. 구동 모드는, 예를 들어, 토크 벡터링, 완전 로킹, 단일 모터, 및 중립을 포함한다.
