REGULATING THE SPEED OF A TURNING VEHICLE BASED ON THE SPEED SETPOINT

摘要

A method is intended to regulate the speed of a vehicle with at least partially automated driving and knowing the radius of curvature of a future portion that it is about to take on its travel lane. This method comprises a step (10-90) in which the speed of the vehicle is regulated as a function of a speed setpoint and, in the event of detection of a radius of curvature of the future portion representative of a bend, it is determined a maximum transverse acceleration that the vehicle can undergo in the bend as a function of the speed setpoint, then a maximum speed that the vehicle would have in the bend if it were subjected to this maximum transverse acceleration in the presence of the radius of curvature detected, then we imposes a deceleration phase on the vehicle up to a deceleration speed chosen as a function of this determined maximum speed.
