Method for operating drive chain of motor vehicle, involves detecting metrologically or analytically temperature of catalyzer of drive chain during throttle cutoff by temperature model

摘要

The method involves detecting metrologically or analytically a temperature of a catalyzer of a drive chain during a throttle cutoff by a temperature model. A drive aggregate of the control device is carried out from operation mode of the throttle cutoff into the operation mode of an impulsive light depending on the temperature of the catalyzer. An auxiliary consumer of a motor vehicle is actively closed, which provides a brake movement in the drive chain.
