REGULATION OF THE SPEED OF A VEHICLE WHEN OVERTAKING ON A BEND

A method is intended to regulate the speed of an at least partially automated vehicle traveling on a first traffic lane adjacent to a second traffic lane. This method comprises a step (-) in which, if a radius of curvature of a future portion representative of a bend is detected, a phase of deceleration to a first deceleration speed adapted to the radius of curvature is imposed on the first vehicle unless it is in the course of overtaking a second vehicle traveling in the second traffic lane, since in that case a current speed of the second vehicle is determined and then, if the first deceleration speed is less than this current speed, the first deceleration speed is replaced with a second deceleration speed greater than this current speed.
