Abstract

A device for controlling a starting procedure of a motor vehicle for initiating a movement of the motor vehicle includes a controller which receives as input, signals generated by an engine shaft speed sensor, a driving speed sensor, a transmission shaft speed sensor, a transmission output shaft speed sensor, and an accelerator pedal position sensor. The controller is operatively connected to the engine for increasing the engine speed above a minimum threshold value when the driver signals his desire for a racing start. The controller is also operatively connected to a clutch activation device for deliberately producing a slip of the driving wheels and for controlling the slip of the driving wheels by controlling a slip of the clutch after a starting time point signaled by the driver.
