Abstract
A method for operating a drive-train (1) of a motor vehicle having an internal combustion engine, a transmission connected between the internal combustion engine and a drive output, and a brake assembly. While the motor vehicle is traveling, if a manual command is given or if defined operating conditions exist, the drive-train (1) is operated in a coasting mode, in which the drive-train (1) is disengaged and the internal combustion engine is turned off. If the internal combustion engine, turned off for the coasting mode, fails to restart despite the existence of a signal to restart the internal combustion engine, a braking process is initiated automatically.
