Cruise control systems for motor vehicles

Speed ​​control apparatus for motor vehicles, with a regulator (10) for outputting a corresponding to the current torque demand request signal ((A) and with a motor controller (22) for controlling an internal combustion engine (26) in response to the request signal, wherein said engine controller (22) is a fuel cut-off function comprises FCO) and a hysteresis module (20) for the fuel cut, characterized in that the hysteresis module (20) is adapted only to activate the fuel cut, when the request signal (a) a first threshold value (S2) below and deactivating the fuel cut, when the request signal exceeds a higher second threshold value (S3).
