Abstract
The present invention pertains to a device for controlling a valve of an internal combustion engine, the device comprising an electromechanical actuator equipped with a magnet, and a processor controlling a defluxing current generating a magnetic field opposed to the magnetic field of the magnet, characterized in that it comprises means for controlling this defluxing current as a function of the open time of the valve and means for determining the rapidity of opening and/or closing of the valve from this open time, the controlled defluxing current ensuring the determined rapidity of opening and/or closing.
