Abstract:
1. A method for controlling deceleration of a motor vehicle having an internal combustion engine with an automated clutch, an accelerator pedal controlling a fuel supply, and a drive train, in which method, when a deceleration is present in which the accelerator pedal is not actuated and the internal combustion engine is connected to the drive train, a deceleration fuel cutoff for stopping the fuel supply is carried out in order to generate a drag torque as a drive torque if the engine speed is higher than a deceleration fuel cutoff threshold (n Sch ), wherein, when a braking request actuated by a brake pedal under a condition wherein the internal combustion engine is uncoupled from the drive train is present, the engine speed is evaluated and an expected engine speed on the basis of the braking request under a condition wherein the internal combustion engine is connected to the drive train is determined; a comparison is carried out between the expected engine speed and the deceleration fuel cutoff threshold (n the internal combustion engine is adjusted to a deceleration mode or a deceleration mode is maintained if the expected or current engine speed is higher than the deceleration fuel cutoff threshold (n
