A method and a control unit for operating a hybrid vehicle, in which at least two units, of which at least one is an internal combustion engine, supply torque for a hybrid vehicle drive. It is provided that an overall required reserve torque be ascertained, and boundary values of currently available reserve torque of each individual unit be determined.

1. A method for operating a hybrid vehicle in which at least two units, of which at least one is an internal combustion engine, supply torque for a hybrid vehicle drive, comprising: ascertaining an overall required reserve torque;determining boundary values of currently available reserve torques of each individual one of the at least two units;in the internal combustion engine, determining a reserve torque that is able to be achieved by increasing an air charge at a simultaneous ignition timing adjustment, the determining of the reserve torque being performed while taking into account a combustibility limit of a fuel;in the case of at least one electric motor as another one of the at least two units, drawing upon as one of the boundary values at least one of a maximum torque, a minimum torque, and a state of charge of an energy store, which supplies the electric motor with driving power;making an apportionment of the overall reserve torque to individual ones of the at least two units within the determined boundary values, as a function of limits of currently available reserve torques; anddetermining an overall gain of a controller having at least one of an overall proportional component and an overall derivative component apportioned to the at least two units corresponding to the apportionment of the overall reserve torque. 2. A control unit for operating a hybrid vehicle in which at least two units, of which at least one is an internal combustion engine, supply torque for a hybrid vehicle drive, comprising: an arrangement for ascertaining an overall required reserve torque;an arrangement for determining boundary values of currently available reserve torques of each individual one of the at least two units;an arrangement for determining, in the internal combustion engine, a reserve torque that is able to be achieved by increasing an air charge at a simultaneous ignition timing adjustment, the determining of the reserve torque being performed while taking into account a combustibility limit of a fuel;in the case of at least one electric motor as another one of the at least two units, an arrangement for drawing upon as one of the boundary values at least one of a maximum torque, a minimum torque, and a state of charge of an energy store, which supplies the electric motor with driving power;an arrangement for making an apportionment of the overall reserve torque to individual ones of the at least two units within the determined boundary values, as a function of limits of currently available reserve torques; andan arrangement for determining an overall gain of a controller having at least one of an overall proportional component and an overall derivative component apportioned to the at least two units corresponding to the apportionment of the overall reserve torque.
