The invention relates chiefly to a method for controlling a controlled variable-stroke oil pump (3) intended to supply pressurized oil to the moving parts of a motor vehicle combustion engine (1) via an oil circuit (1), characterized in that it comprises the step of running the oil pump (3) in a mechanically regulated mode so as to maximize a pressure in said oil circuit (1) when at least one of the following conditions is met: - an outside temperature is lower than a first calibratable threshold and/or a temperature in a passenger compartment of the vehicle is lower than a second calibratable threshold; and/or - a combustion engine (1) downgraded combustion output strategy has been activated in order to raise the temperature inside the passenger compartment. Another subject of the invention is the corresponding engine management system.
