Abstract
An internal combustion engine (E) has associated control devices (ECU, GSCU, SCU) for controlling the engine in a manner such that the engine delivers a driving torque (CM) which is variable in dependence on predetermined measured parameters, in particular on the position (&agr;) of the accelerator pedal (AP), and sensors (S1, S2) for detecting the position (&agr;) of the accelerator pedal (AP), and the rate of rotation (&ohgr;M) of the shaft (M) of the engine (E) or the forward speed (v) of the motor vehicle, respectively. The control system (ECU, GSCU, SCU) associated with the engine (E) is arranged:—to acquire from the sensors (S1, S2) the position (&agr;) of the accelerator pedal (AP) and the rate of rotation (&ohgr;M) of the engine (E), or the forward speed (v) of the motor vehicle;—to determine, in accordance with predetermined methods, the power (PT) to be applied to the driving wheels in dependence on the measured position (&agr;) of the accelerator pedal (AP) and on the calculated or acquired forward speed (v) of the vehicle, and to calculate, in dependence on the value determined for the power (PT) to be applied to the driving wheels and on the forward speed (…
