Abstract: A speed control method for controlling the speed of an autonomous vehicle provided with at least one autonomous driving module and one geolocation module, the vehicle being capable of following a route, which is predefined and segmented according to at least one segmentation comprising of a plurality of segments, each associated with: an interval of geolocation data; and a set of values for nominal maximum travel speed of the autonomous vehicle, each speed value being associated with a distinct time slot; the method comprising: the acquisition, from the on-board geolocation module, of an instantaneous geolocation data item of the autonomous vehicle associated with a time instant; as a function of the instantaneous geo-location data item and the time instant, the determination, of the segment currently being traversed and/or to be traversed, and of the associated nominal maximum speed value.
