A device for controlling the engine (108) of a vehicle comprising an accelerator pedal (101) and an engine speed control circuit (102, 103, 106, 109) comprising in particular: a circuit (103) for closed-loop control of the engine speed, a circuit (102) for interpreting the position of the accelerator pedal, which supplies an engine speed setpoint to the circuit (103) for closed-loop control of the engine speed depending on the position of the accelerator pedal (101), a circuit (106) for estimating loads external to the vehicle, characterized in that it is provided with a circuit (109) for estimating maximum speed which gives a maximum engine speed likely to be reached by the engine as a function of the estimate of external loads supplied by the circuit (106) for estimating external loads and in that this maximum speed is supplied to the circuit (102) for interpreting the position of the accelerator pedal and makes the engine speed setpoint vary independently of the position of the accelerator pedal (101), so as to reproduce some of the sensations usually felt by the driver when the engine is torque controlled. The invention also covers the associated method.
