Disclosed is a method intended to regulate the speed of a vehicle with at least partially automated driving and knowing the radius of curvature of a future segment which it is about to take on its route. This method comprises a step (-) which involves regulating the speed of the vehicle in accordance with a speed setpoint and, in the event that a radius of curvature of the future segment representative of a bend is detected, determining a maximum transverse acceleration that the vehicle can undergo in the bend depending on the speed setpoint, then a maximum speed that the vehicle would have in the bend if it underwent this maximum transverse acceleration in the presence of the detected radius of curvature, then imposing a deceleration phase on the vehicle until a deceleration speed chosen as a function of this determined maximum speed is reached.

Control of the speed of a vehicle when cornering in accordance with the speed setpoint

A method is intended to regulate the speed of an at least partially self-driving vehicle, knowing the radius of curvature of a future position it is preparing to take on a course along which it is travelling. This method comprises a step (-) in which the speed is regulated as a function of a speed set point and, if a radius of curvature of the future position which is representative of a curve is detected, a phase of deceleration down to a chosen speed followed by a phase of acceleration until the speed setpoint is obtained are imposed on the vehicle. In this step (-), when the driver imposes acceleration on his vehicle during the deceleration phase, this deceleration phase is halted and then another phase of acceleration until the speed set point is obtained is imposed on the vehicle.
