A method for evaluating the deceleration law of a vehicle including an accelerator pedal, a brake pedal, and a powertrain including an engine, a gearbox and a unit for disconnecting the engine and gearbox, the deceleration law being defined for a discrete state of the powertrain. The method includes a first step of evaluating driving parameters, including measuring the speed (v) of the vehicle, evaluating the engaged gearbox ratio, evaluating the state of closure of the disconnecting unit, detecting the position of the accelerator pedal, detecting the position of the brake pedal, evaluating the slope (a) of the road on which the vehicle is traveling, evaluating the mass (m) of the vehicle. If the accelerator pedal is in a released position and if the brake pedal is in a released position, a second step including recording the speed (v) of the vehicle and the slope (a) of the road. A third step of computing a first coefficient (f0′), a second coefficient (f1′) and a third coefficient (f2′) of the deceleration law representing the forces F(v) being exerted on the vehicle, with the exception of the gravitational forces being exerted on the vehicle, according to the equation:F(v)=f0′+f1′*v+f2′*v2.
