A method for controlling a reversible DC-DC converter of a motor (5) vehicle provided with a power train comprising an internal combustion engine (2) mechanically connected to an electric machine (3) powered by an inverter (4), the inverter (4) being electrically connected to at least one low-voltage battery (7) by way of the reversible DC-DC converter (5), the DC-DC converter (5) furthermore being connected to auxiliary equipment (8). The method comprises the following steps: the difference between a setpoint and an estimate of the power at the terminals of the DC-DC converter (5) is determined, and a voltage setpoint at the terminals of the DC-DC converter (5) is determined as a function of the difference determined, and of a tolerance value such that the voltage setpoint is able to be determined when the current flowing at the terminals of the DC-DC converter is zero.
