Electrically operable final drive powertrain, method for controlling a final drive powertrain, computer program product and control unit for controlling a final drive powertrain

A method for controlling a final drive powertrain of a motor vehicle that includes an electric machine which can be coupled to a vehicle wheel of the motor vehicle in a torque-transmitting manner, a transmission assembly arranged in the torque flow between the vehicle wheel and the electric machine, a brake for braking the vehicle wheel, a first clutch arranged in the torque flow between the electric machine and the brake via which the brake can coupled and decoupled from the torque flow, and a second clutch arranged in the torque flow between (1) the electric machine and the transmission assembly or (2) the brake and the transmission assembly, the second clutch being operable to couple and decouple the transmission assembly from the torque flow, comprising the steps of:

• entering a first operating state, wherein the first clutch is in a decoupled state, the second clutch is in a decoupled state, and the brake is released;
• entering a second operating state, wherein the second clutch is coupled and the brake is released;
• entering a third operating state, wherein the first clutch is in a coupled state, the second clutch is in the coupled state, and the brake is actuated;
• and
• entering a fourth operating state, wherein the first clutch is in the decoupled state, the second clutch is in a coupled state, and the brake is actuated.

An electrically operable drive powertrain for a motor vehicle, comprising:

• an electric machine which can be coupled to at least one vehicle wheel of the motor vehicle in a torque-transmitting manner;
• a transmission assembly arranged in the torque flow between the vehicle wheel and the electric machine;
• a brake via which the vehicle wheel can be braked;
• a first clutch arranged in the torque flow between the electric machine and the brake and operable to couple and decouple the brake from the torque flow;
• and
• a second clutch operable to couple and decouple the transmission assembly from the torque flow.
