A method for regulating the buoyancy of an underwater vehicle in such a way that it substantially exhibits a predetermined target buoyancy Fc when it is immersed in a volume of liquid delimited by a first surface and a second surface, along a vertical axis, the method includes starting from an initial buoyancy of the vehicle that keeps the vehicle at the level of the first surface, a first step of modifying the density of the vehicle so that it moves closer to the second surface, the first step being implemented as far as a second step of detecting the crossing, by the vehicle, of a predetermined non-zero threshold on distance with respect to the first surface, along the vertical axis, then a third step of modifying the density of the vehicle until the vehicle exhibits substantially the target buoyancy.
