Abstract:
1. A method for operating a hybrid drive system having multiple drive units, each drive unit having a drive motor and a motor control unit, comprising: activating at least one of the motor control units in order to request a partial drive torque from at least one of the drive units according to a drive strategy; executing by at least one of the motor control units an adaptation function when a predefined condition is present for the adaptation function; determining a frequency of an execution of the adaptation function; and determining whether the determined frequency of the execution of the adaptation function falls below a predefined frequency threshold value, wherein the drive strategy is selected as a function of whether the frequency of the execution of the adaptation function in the at least one motor control unit falls below the predefined frequency threshold value, and wherein the drive strategy is selected as a function of the determined frequency of the execution of the adaptation function in the at least one motor control unit.
