Brief description of the piloting of an oil pump is to improve a service temperature in the passenger compartment of a motor vehicle and the engine computer corresponding

摘要

The present invention relates mainly to a process for the piloting of an oil pump (3) is driven at variable capacity intended to be supplied with oil under pressure of the elements in movement of a heat engine (1) of a motor vehicle via an oil circuit (1), characterized in that it comprises the step to operate the oil pump (3) in a controlled mechanically so as to maximize the pressure in the oil circuit (1), when at least one of the following conditions is satisfied: - an external temperature is lower than a first adjustable threshold and / or a temperature in a passenger compartment of the vehicle is less than a second adjustable threshold, and / or - a strategy of degradation of a combustion efficiency of the thermal engine (1) is activated in order to increase the temperature inside the passenger compartment. The present invention also relates to the engine computer corresponding.
