Definitions

  • the present invention relates to an information management system fuel consumption of a motor vehicle engine.
  • the invention relates to such a management system for a vehicle engine equipped with gas purification means its exhaust, whose operation is controlled by a calculator adapted to determine a first quantity of fuel to be injected in the engine for normal operation and a second amount of fuel to inject into the engine to trigger a regeneration means of purification.
  • This regeneration phase must be triggered regularly by example depending on the state of charge of the purification means, by the calculator engine operation control.
  • this regeneration is usually triggered by increasing the amount of fuel injected into the engine to enrich the air / fuel mixture to cause an increase in temperature exhaust gases in order to trigger the regeneration of the means purification, for example by triggering the combustion of particles trapped in a particle filter.
  • this engine consumption information is transmitted to the remainder of the equipment of the vehicle, as for example to the means of management consumption information, through a transmission network embedded information.
  • consumer information management means comprise for example means for displaying the instantaneous consumption information intended for the users of the vehicle and means of calculating average consumption and autonomy of it (as known from the document EP 1 018 449 A2).
  • the object of the invention is therefore to solve these problems.
  • the subject of the invention is a management system of fuel consumption information of a motor vehicle engine equipped with means for purifying the exhaust gases thereof, the operation is controlled by a control computer, adapted to determine a first quantity of fuel to be injected into the engine for its operation normal and a second amount of fuel to be injected into the engine to trigger a regeneration phase of the purification means and connected by an information transmission network to management means consumption information including display means instantaneous consumption information and calculation means of average consumption and vehicle autonomy, characterized in that the calculator is associated with successive transmission means on the network, when a regeneration phase purification means, first and second quantities of fuel determined for receiving means corresponding means of management, to deliver the first quantity of fuel to the display means and the second amount of fuel to the means Calculation.
  • FIG. 1 shows the general structure of a system fuel consumption information management system of an engine of motor vehicle.
  • the motor is designated by the general reference 1 and has an exhaust line designated by the general reference 2, in which are integrated means 3 for purifying the exhaust gases of the engine.
  • These purification means are for example formed by a trap to NOx, a particulate filter, etc.
  • this control computer is then adapted to determine a quantity of fuel to be injected into the engine to meet the motorization needs of the vehicle.
  • This regeneration phase is also triggered by the calculator 4 from trigger information, such as for example from pollutant load purification means or other.
  • control computer of the engine determines another quantity of fuel to be injected into the engine, additional compared to that required for the normal operation of the engine, for cause an enrichment of the air / fuel mixture which results in a increase in the exhaust temperature of it, this increase of temperature being of a nature to favor the regeneration of the means of purification.
  • this calculator engine operation control is also connected to means of management of consumption information, designated by the reference 5 in this figure, these means comprising for example means display of instantaneous engine fuel consumption information designated by the general reference 6 and means for calculating the average consumption vehicle and its autonomy, designated by general reference 7.
  • These display means comprise, for example, an integrated display to the dashboard of the vehicle to deliver a consumption information instant engine to the users of it, while the means of calculation are formed for example by any appropriate calculator.
  • the engine operation control computer and these management means are connected by an information transmission network designated by the general reference 8 in these figures, formed for example by a multiplex network.
  • the engine control computer 4 is associated with means 9 for successive transmission on the network, during a regeneration phase purification means, first and second quantities of fuel determined by the calculator, the first quantity, that is to say that determined for the normal operation of the engine, being intended for the means information display 6 and the second quantity, that is to say the determined quantity for the regeneration of the purification means being intended for the means of calculation 7.
  • the means of management are associated with means of 10, allowing the identification of the nature of the information of amount of fuel received from the calculator, across the network, and to direct them to the corresponding means, that is to say the display means or the calculation means.
  • the display means 6 will receive therefore the first quantity to display it, while the calculation means will receive the second quantity for the rest of the average consumption calculations and autonomy.
  • FIG. 2 illustrates the triggering of a regeneration which is caused as shown in Figure 3, by an increase in the amount of fuel injected into the engine.
  • the transmission is illustrated successively and alternately fuel quantity information injected into the engine for its normal operation or for regeneration.
  • the first and second quantities of fuel emitted on the network are identified by the means of corresponding reception associated with the management means.
  • this information can be associated with information identification numbers which, as illustrated in Figure 5, can be be formed by a data bit associated with the quantity information of fuel, this bit being fixed at a first value for the first quantity of fuel and a second value for the second fuel quantity.
  • the quantity Transmitted is the amount of fuel to be injected for operation normal motor while while the data bit is zero
  • the quantity transmitted is the quantity injected for the regeneration of the means of purification.
  • the display means then receive a consumption information engine, which avoids the problems mentioned above, while that the computing means receive actual consumption information of the motor, during the regeneration phase, which makes it possible to preserve the precision calculating the average consumption of the latter and the vehicle's range.
