In a method for operating a hybrid drive system having multiple drive units each having a drive motor and a motor control unit, the motor control units are activatable in order to request partial drive torques from the drive units according to a drive strategy. At least one of the motor control units is configured to execute an adaptation function when an adaptation function condition is present. The drive strategy is selected as a function of a frequency of an execution of the adaptation function in the motor control unit.

Method and device for operating a hybrid drive system

In a method and a device for operating a drive unit, a first output variable of the drive unit is restricted; a setpoint value of a second output variable of the drive unit is specified; and an actual value of the second output variable of the drive unit is determined. The setpoint value is compared with the actual value, and if it is determined that the actual value does not exceed the setpoint value, then the first output variable is restricted to a first value. If it is determined that the actual value exceeds the setpoint value, then the first output variable is restricted to a second value smaller than the first value.

Method and device for operating a drive unit

A method for ascertaining information about a device that has been exposed to a temperature, permitting a simple and reliable means of ascertaining information about the aging of the device. The temperature of the device is determined. Depending on the temperature or the temperature change achieved by the device, at least one counter is incremented. Information about the aging of the device is ascertained as a function of the counter reading achieved.
