ABSTRACT:
A motor vehicle starter is cut out automatically as soon as the engine is running by itself. The cut-out is controlled by a method in which the starter supply voltage is measured and the starter is cut out when this voltage reaches a threshold value. On closing of the ignition switch, but before any power is supplied to the starter, the starter supply voltage is measured for several values of current in at least one circuit in the wiring network of the vehicle connected to the vehicle battery. The value of the threshold voltage is then calculated from these measurements, as a function of parameters that characterize the electrical circuitry of the vehicle at the time of starting the engine, at least one of these parameters being capable of being determined from the current measurements.
