  • Torque overlay device for a hybrid drive system, and a method for operating such a hybrid drive system
    Patent number: 9845088
    Abstract: The invention relates to a torque overlay device for use in a hybrid drive system for motor vehicles having an internal combustion engine, an electric motor and the torque overlay device, wherein a torque of the internal combustion engine and of the electric motor are overlaid using the torque overlay device. The torque overlay device is connected, on the output side, to a driven element of the vehicle, and includes a first and a second torque input and a torque output, as well as a first transmission device and a second transmission device. The electric motor can be coupled to the first torque input in a torque-resistant manner, and the internal combustion engine can be coupled to the second torque input in a torque resistant manner, where the first torque input is connected to the first transmission device and the second torque input is connected to the second transmission device, both in a torque-resistant manner.
