A method for the assistance of a motor vehicle driver during a drive off maneuver

A method for the assistance to a motor-vehicle driver (1) during a drive-off manoeuvre, wherein the motor vehicle (1) comprises: - an internal-combustion engine (2); - a transmission, connected to the internal-combustion engine (2) by means of a clutch that can be operated by the driver, said transmission further comprising a gearbox that can be operated by the driver; - an engine-control unit, operatively connected to the internal-combustion engine (2) and including an engine-r.p.m. controller (32); - a first pedal (8) for the actuation of the clutch between a disengaged position, in which the transmission is uncoupled from the internal-combustion engine, and an engaged position, in which the transmission is coupled to the internal-combustion engine; - a second pedal (10) for actuating a braking system of the motor vehicle (1); - first sensor means (14), designed to detect a position of the first pedal (8); - second sensor means (16), designed to detect a position of the second pedal (10); - third sensor means (22), designed to detect an advancement speed of the motor vehicle (V vehicle ); and - fourth sensor means (24), designed to detect an acceleration of the motor vehicle (1). The method comprises: - a first step of recognition of a start of a drive-off manoeuvre as a function of signals (S 14, S16, S22) coming from the first, second, and third sensor means (14, 16, 22); - a second step (30) of calculation of a value of target rotational speed of the drive-off manoeuvre (n obj,do ); - a third step of sending of the value of target rotational speed of the drive-off manoeuvre (n obj,do ) to the engine-r.p.m. controller (32); - a fourth step of calculation of a gain of the engine-r.p.m. controller (32) as a function of a signal (S24) coming from the fourth sensor means; and - a fifth step of calculation of a value of target torque (T obj ) by the engine-r.p.m. controller (32) to maintain a rotational speed of the internal-combustion engine equal to the value of target rotational speed of the drive-off manoeuvre (n obj,do ), wherein the second, third, fourth, and fifth steps develop if in said first step a beginning of a drive-off manoeuvre is recognized and are repeated in sequence until the end of the drive-off manoeuvre.
