Abstract

A process for controlling a drive train with an internal combustion engine, a transmission and an automatically actuated brake system. In the event of a defect of the transmission, retardation is effected by means of the automatically actuated brake system in order to avoid impermissibly high speeds in the drive train.

Claims (4)

1. A process for controlling a drive train of a motor vehicle with an internal combustion engine, an automated parallel shift transmission with first and second partial drive trains, and an automatic brake system, the process comprising:

detecting a blocked gear in the first partial drive train of the automated parallel shift transmission while the vehicle is in motion; and,

operating the automatic brake system to retard the motor vehicle, wherein:

when the transmission input shaft of the first partial drive train is accelerated when the second partial drive train is operated with a gear with a higher ratio than the blocked gear.
