Abstract:
A method to control a road vehicle during a slip of the drive wheels, which are caused to rotate by an internal combustion engine provided with a plurality of cylinders arranged in two banks, and with a plurality of fuel injectors each injecting fuel into a corresponding cylinder. The control method comprises the steps of: detecting a slip of at least one drive wheel; and controlling the internal combustion engine, only during a slip of at least one drive wheel, with a signalling law, which causes the internal combustion engine to work in an abnormal manner so as to generate an abnormal vibration and/or an abnormal noise, which can be perceived by the driver. The internal combustion engine has two twin control units, each of which is associated with a corresponding bank, controls all and the sole injectors of its own bank and actuates the signalling law completely independently of and autonomously from the other control unit.
