The invention relates to a driving assistance method which is intended for use on a slope. According to the invention, the vehicle comprises an accelerometer which can measure a longitudinal acceleration of the vehicle as measured longitudinal acceleration. The inventive method comprises the following steps consisting in: determining the instantaneous value of the slope (p) on which the vehicle is positioned, by calculating an instantaneous longitudinal acceleration from the measurements taken by wheel speed sensors, and, subsequently, comparing the instantaneous longitudinal acceleration with the longitudinal acceleration measured by the accelerometer; determining (156) a theoretical brake torque (Γth) as a function of the slope such that the vehicle reaches a desired speed (Vo); correcting (162) the theoretical brake torque value in order to obtain a target brake torque (Γ C ); and emitting (163) a signal corresponding to the target brake torque in the direction of the brake regulation system.
