Abstract:
1. A method for controlling the electric pump ( 22 ) of an engine of a vehicle said engine being comprised of a clutch, gears and a motor, said pump adapted to supply pressurised operating fluid to at least one actuator ( 10 , 12 ) of an automatic robot transmission ( 1 ) comprised of said clutch and gears in order to cause the opening/closing of the clutch and/or the selection and engagement of the gears, in which the voltage supplied to the electric pump is carried out in order to cause the electric pump to rotate, characterised in that it comprises the step of regulating said voltage as a function of a different operating condition monitored in the vehicle during which a different voltage is generated (V 1 , V 2 , V 3 , V 4 , V 5 , V 6 and V 7 ) for the motor of the electric pump so as to obtain respective different speeds of rotation (n 1 ,n 2 , n 3 , n 4 , n 5 , n 6 and n 7 ), each said different voltage being selected in conjunction with a respective operating situation detected in the vehicle.
