Abstract
A process for controlling the speed of a vehicle travelling on a slope is disclosed. The vehicle is equipped with an electronic system which, through active brake intervention, adjusts the speed of the vehicle to a predetermined constant hill descent speed upon actuation of a hill descent control mode. The process comprises generating in the electronic system a continuously variable desired speed, and upon actuation of said hill descent control mode, the desired speed is continuously adjusted until it is equal to the predetermined constant hill descent speed. While the desired speed is being adjusted, the vehicle speed is continuously adjusted through active brake intervention until it is equal to the desired speed, so that after a transition period, the vehicle speed is equal to the predetermined constant hill descent speed.
