Abstract

In a method for controlling a hybrid drive which is driven by an internal combustion engine designed as a first drive unit, and by a second drive unit, the internal combustion engine and the second drive unit contribute individually or jointly to the drive of the vehicle, and pollutant emissions are kept at the lowest possible level in all operating states of the hybrid drive. At least one control function for the internal combustion engine is carried out by a coordination unit which determines the point in time at which the internal combustion engine or the drive unit alone, or the internal combustion engine and the drive unit simultaneously, contribute to the drive of the vehicle.
