Definitions

  • the present invention relates to a method for supplying electrical equipment such as an electromagnetic actuator that can be used in particular for actuating motor vehicle thermal engine valves.
  • Such an electromagnetic actuator is incorporated in a supply network in which it is connected via a capacitive element to a voltage converter which is itself connected to an accumulator and to an alternator and which is regulated in voltage. and limited in current.
  • the operation of the electromagnetic actuator generates on the output network of the voltage converter current calls which are reflected in the input of the voltage converter. This results in current peaks whose characteristics are incompatible with the response time of the alternator so that, the alternator can not provide the necessary current, it is taken from the accumulator. However, these peaks of high amplitude current causes a heating of the accumulator which makes the standard accumulators unsuitable for such use.
  • the document FR 2 766 005 A discloses a method of powering an electrical equipment according to the preamble of claim 1.
  • An object of the invention is to provide an economical and efficient way to supply such an electrical equipment optimally.
  • the current regulation of the voltage converter which is thereby controlled as a current generator makes it possible to maintain the current supplied by the accumulator at the input of the voltage converter at a substantially constant value. This makes it possible to have a minimum volume of the capacitive element.
  • the average intensity is evaluated in a predictive manner from control data of the actuator.
  • the intensity reference is thus obtained by anticipation.
  • This calculation method makes it possible to obtain the intensity setpoint in a simple manner and to avoid using as a setpoint a periodically measured intensity which requires having a fast regulation and a high capacity as a reserve of energy in the event of sudden variation of the current.
  • the intensity setpoint is equal to the evaluated average intensity plus a correction factor for an output voltage of the converter which is rising and lower than an upper voltage limit, and the intensity setpoint is equal to at the rated average intensity minus the correction factor for a converter output voltage that is down and higher than a lower voltage limit.
  • the correction factor is determined in such a way that the input current of the converter is maintained within a determined range compatible with the characteristics of the accumulator and that the output voltage of the converter is maintained in a determined range compatible with the characteristics of the equipment. This makes it possible to limit the frequency of calculation of the setpoint.
  • the correction factor corresponds to an imprecision of the evaluation of the average intensity and is preferably equal to about 10% of the average intensity evaluated.
  • the correction factor makes it possible to compensate for any differences between the average intensity evaluated and the average intensity actually consumed.
  • the correction factor thus makes it possible to determine a range of average intensities at which the average intensity actually consumed has a high probability of belonging.
  • the process according to the invention is here intended to supply an electromagnetic actuator that can be used to actuate valves of a thermal engine of a motor vehicle.
  • Such an actuator comprises electromagnetic coils which, when excited, attract a pallet of which at least one valve is secured to bring and maintain the valve in the open position and in the closed position.
  • the current necessary for the excitation of the coils must be supplied to them in the form of peaks of high amplitude and of short duration according to an excitation frequency determined by a computer of the vehicle which drives the actuator in current.
  • control data function such as depression of the accelerator pedal, engine speed, vehicle speed and more generally engine load parameters.
  • the electromagnetic actuator 1 is connected to a supply circuit 2 which comprises an accumulator 3 connected to a voltage converter 4.
  • the accumulator 3 delivers a voltage of the order of 12 volts and is connected to an alternator not shown to be recharged.
  • the voltage converter 4 is arranged to convert the input voltage from 12 volts to an output voltage of the order of 42 volts.
  • the voltage converter 4 is connected to the electromagnetic actuator 1 by a capacitive element 5 arranged to allow storage of the energy supplied by the voltage converter 4.
  • the method according to the invention consists in regulating the voltage converter 4 in current from an intensity reference corresponding to a mean intensity between two peaks.
  • the average intensity is evaluated predictively from the voltage in the accumulator 3 and the peak power that will be consumed over a predetermined cycle time. This power depends on the engine speed which can be deduced from the control data of the actuator used by the vehicle computer.
  • the voltage converter thus controlled forms a current generator that is slaved to the average power that will be consumed during the next thermal cycle.
  • Regulation is carried out in a conventional manner by modulating the input voltage of the converter as a function of the current measured at the output of the converter.
  • the intensity setpoint is thus equal to the evaluated average intensity plus the correction factor for an output voltage of the converter which is rising and which is lower than an upper limit of voltage, and the intensity setpoint is equal to l the rated average intensity minus the correction factor for a down converter output voltage that is greater than a lower voltage limit.
  • This correction factor corresponds to an uncertainty as to the moment of appearance of the next intensity peak, that is to say a possible difference between the average intensity evaluated and the average intensity actually consumed.
  • the correction factor is approximately 10% of the average intensity evaluated.
  • the output voltage of the converter varies.
  • the actuator being driven current, variations in the voltage are not a problem. These variations, however, are maintained in the range delimited by the lower and upper voltage limits. These limits are determined so that the corresponding voltage range is compatible with the characteristics of the actuator. For example, if the characteristics of the actuator allow operation in a voltage range between 30 volts and 50 volts, a lower limit equal to about 34 volts and an upper limit equal to about 44 volts is chosen.
  • correction factor is equal to 10% in the example described, it may have a different value. It is also possible to do without a correction factor.
  • the lower and upper limits of voltage can also be modified, in particular be closer or more distant from each other depending on the characteristics of the equipment to be powered.
  • the invention is not limited to the supply of an electromagnetic actuator but can be used to power any electrical equipment operating in a pulsed mode.
  • the invention can be applied to a flashing system of the projectors of the vehicle.
