A method for controlling a hybrid drive of a vehicle, the hybrid drive including an internal combustion engine and at least one electric machine as the drive motors, and the output shafts of the drive motors being operatively connectable to a drive train of the vehicle. It is proposed that in response to a negative torque demand on the drive train of the vehicle (braking), the at least one electric machine and the transmission are controlled in generating operating mode based on characteristic maps.

What is claimed is: 1. A method for controlling a hybrid drive of a vehicle, the hybrid drive including an internal combustion engine and at least one electric machine as drive motors, and output shafts of the drive motors being operatively connectable to a drive train of the vehicle, the method comprising: in response to a negative torque demand on the drive train of the vehicle, controlling the at least one electric machine in generating an operating mode based on a control map; wherein the control map is bounded by limit curves which limit an operating range of a brake energy regeneration, a minimum limit curve defining a transition between a purely regenerative operation including active input of electric power into a vehicle electrical system and a purely regenerative operation including an electric power demand placed on the vehicle electrical system, and a maximum limit curve defining a transition between a purely regenerative operation including active input of electric power into the vehicle electrical system and a combined regenerative and mechanical operation, and wherein the maximum limit curve is a function of the vehicle speed, and at each speed has a value which is a lower of: (a) a maximum torque of the at least one electric machine and (b) a torque at which a maximum battery current can be produced. 2. The method as recited in claim 1, wherein the at least one electric machine is controlled as a function of a desired brake torque and a vehicle speed. 3. The method as recited in claim 1, wherein control is via a regeneration strategy block that receives required signals via an interface and that has function modules that generate control signals for the at least one electric machine. 4. The method as recited in claim 3, further comprising: causing a brake module selector to selectively activate different operating modes for braking as a function of the required signals present at the interface. 5. The method as recited in claim 1, wherein the available operating modes are purely regenerative braking, combined regenerative and mechanical braking, and purely mechanical braking. 6. The method as recited in claim 1, wherein a unit control specifies, as control signals, at least one of a desired torque and a desired speed for the at least one electric machine. 7. The method as recited in claim 6, further comprising: reading the control signals out from a control map. 8. The method as recited in claim 7, further comprising: taking into account a maximum generator current of the at least one electric machine as a parameter in the control signals. 9. The method as recited in claim 1, further comprising: causing a shift logic to select a transmission stage of a transmission that allows the at least one electric machine to achieve an optimum regenerative efficiency. 10. The method as recited in claim 9, wherein the shift logic uses shift maps. 11. The method as recited in claim 9, wherein the shift logic takes into account actual transmission stages specified by a higher-level vehicle control system, and, in the case of deviations of more than one transmission stage, corrects the transmission stages for regenerative braking. 12. The method as recited in claim 9, wherein the shift logic takes into account a gradient of a desired deceleration torque. 13. The method as recited in claim 1, further comprising: at least one of calculating and determining at least one of the control map and a shift map based on specific actual parameters of a hybrid drive. 14. The method as recited in claim 1, further comprising: storing the control map and a shift map in the vehicle in a control unit that can be accessed by a regeneration strategy block.
