    摘要: A drive system for a motor vehicle comprising an internal-combustion engine, an electric machine coupled to the internal-combustion engine, and a transmission device through which a ratio change can be implemented without a tractive power interruption is described. Also described is a control device for controlling the electric machine and for controlling the transmission device. The control device is constructed such that, in the event of a braking demand, the demanded total braking torque is at least proportionally provided by the electric machine, and, in the case of an existing braking demand with a constant total braking torque and a change of the transmission ratio implemented in the presence of this braking demand, the electric machine is controlled such that the total braking torque changing because of the ratio change is at least partially compensated, so that a constant total braking torque according to the braking demand is maintained.
