Abstract
Disclosed is a method for controlling a module for driving a transistor of a DC-DC voltage converter allowing at least one fuel injector of a motor-vehicle internal combustion engine to be controlled. The method includes a step of measuring the amplitude of the current flowing through that of the first switch or of the second switch that is in the on state, a step of determining the electric charge transported by the current, and a step of interrupting the operation of the drive module when the determined electric charge is higher than a preset maximum electric-charge threshold.
