Abstract
What is described is a control system for controlling the driving-away maneuver in a motor vehicle provided with a gearbox comprising a primary input shaft which can be coupled to a drive shaft of a propulsion system of the vehicle by means of a servo-assisted friction clutch, wherein a control unit receives at its input signals indicating a command imparted by the driver of the motor vehicle by operating the accelerator pedal, and generates—on the basis of a mathematical reference model—reference torque request signals indicating the reference torques requested from the drive shaft and from the friction clutch during the driving-away manoeuvre, and also generates—by comparison between signals indicating the estimated angular velocities of the drive shaft and of the primary gear shaft, and detected signals indicating the actual angular velocities of the drive shaft and of the primary gear shaft—corresponding corrective contributions, in such a way as to construct command signals for controlling torque actuator devices of the propulsion system and of the friction clutch, for controlling the driving-away manoeuvre in the motor vehicle.
