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. In addition, the transmission devices may each be coupled, on the driven side, to the torque output of the torque overlay device in a torque-resistant manner.

Torque overlay device for a hybrid drive system, and a method for operating such a hybrid drive system

A method is provided for the open-loop or closed-loop control of at least one operating parameter of an electric energy accumulator influencing the aging state of the electric energy accumulator. The method determines the actual aging state of the electric energy accumulator, compares the actual aging state with a target aging state predefined for the momentary age of the energy accumulator, and restricts an operating parameter range permitted for the at least one operating parameter if the actual aging state is worse than the target aging state.
