Abstract:
A method for controlling deceleration of a motor vehicle having an internal combustion engine with an automated clutch, in which method, when a deceleration is present, a deceleration fuel cutoff 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 wherein when a braking request is present, the effect of the engine speed is evaluated, a comparison is carried out between the expected engine speed or the current engine speed and the deceleration fuel cutoff threshold, and the internal combustion engine is adjusted to a deceleration mode or a deceleration fuel mode is maintained only if the expected or current engine speed is higher than the deceleration fuel cutoff threshold.
