  • DE 42 14 648 AI shows a system for controlling an internal combustion engine with a turbocharger, the air mass in the intake manifold being determined via the engine speed, the amount of fuel to be injected, a recirculated exhaust gas amount and from the power of the compressor and the turbine of the turbocharger.
  • the invention is based on the object of determining further operating variables of an internal combustion engine without the use of special sensors. Advantages of the invention
  • the ambient air pressure can be determined from the compressor map by specifying the turbine speed, the charge air pressure and the air mass flow supplied to the compressor. Or it can be determined from the compressor map, the turbine speed given the ambient pressure, the charge air pressure and the air mass flow supplied to the compressor.

  • the turbine 4 in the exhaust gas duct 3 is bridged by a bypass 6, in which a controllable valve 7 is located.
  • a number of sensors are provided for detecting various operating variables of the internal combustion engine.
  • a temperature sensor 9 in the intake pipe 2 which measures the ambient air temperature tu
  • a sensor 10 for example HFM sensor
  • an air pressure sensor 11 is arranged in the intake manifold 2 and measures the ambient air pressure ud. The ambient air pressure ud is measured by means of the sensor 11 in the air flow direction in front of an air filter 12, whereas the air mass sensor 10 and the temperature sensor 9 are arranged in the air flow direction behind the air filter 12.
  • Speed sensor 13 is provided, which detects the turbine speed nt. All the sensor signals ld, tu, Im, ud and nt mentioned are fed to a control unit 14 via signal lines (shown in dashed lines).
  • the ambient air pressure is a parameter that is used, for example, to calculate the height-dependent response speed of the exhaust gas turbocharger to release the adaptation of the boost pressure regulator or to limit the compressor pressure ratio to protect against compressor pumps and against overspeed in height or to switch off ON-Board diagnostic functions above one certain height or to correct the load detection parameters (e.g. residual gas pressure in the cylinder).
  • the function diagram shown in FIG. 3 illustrates how an ambient air pressure ud * is determined by the control unit 14 instead of the measured ambient air pressure ud.
  • the data of a compressor map KF are stored in the control unit 14.
  • FIG. 2 shows an exemplary compressor map - is usually provided by the manufacturer of the exhaust gas turbocharger. It provides a clear relationship between the air mass Im fed to the compressor, the compressor pressure ratio - this is the quotient of the air pressure on the pressure side and the air pressure on the suction side of the compressor - and the turbine speed nt.
  • the compressor map in FIG. 2 makes it clear that with increasing turbine speed nt (e.g. starting at a speed of 60,000 and ending at a speed of 180,000) the ratio between the air pressure ld on the pressure side and the air pressure sd on the suction side of the compressor 5 increases ,

  • block KF in which the compressor map of the turbocharger is stored, is supplied with the air mass Im measured by sensor 10 and the turbine speed nt detected by sensor 13. From these two values, the block KF derives the third map size from the compressor map, namely the ratio of the air pressure ld (boost pressure) on the pressure side of the compressor and the air pressure sd on the suction side of the compressor 5. This air pressure ratio ld / sd divided by the charge pressure ld measured by the sensor 8, so that after a subsequent reciprocal formation in block KW, the air pressure sd is available on the suction side of the compressor. Actually, the air pressure sd on the suction side of the compressor would correspond to the ambient air pressure ud * to be determined.

  • the actual ambient air pressure ud * is obtained from the air pressure sd derived from the compressor map KF. This can now be used in the control process for the internal combustion engine.
  • FIG. 4 shows a functional diagram according to which the turbine speed nt can be determined if the sensor 13 is to be dispensed with.
  • the block KF in which the compressor map is stored, the air mass Im measured by the sensor 10 and the ratio of the boost pressure ld, which is detected on the pressure side of the compressor 5 by the sensor 8, and the air pressure sd on the suction side of the compressor 5 supplied.
  • the compressor map KF can then be used Derive turbine speed nt *.
  • the ratio of the boost pressure ld and the air pressure sd on the suction side of the compressor 5 can, for. B. be formed by means of a multiplier MP, which multiples the boost pressure ld measured by the sensor 8 with the reciprocal value of the air pressure sd formed by the block KW on the suction side of the compressor 5.
  • the air pressure sd on the suction side of the compressor 5 actually corresponds to the ambient air pressure ud, which is detected by the sensor 11.
  • the correction values kl and k2 already described above are formed here, which compensate for the two influences by subtractively superimposing the ambient air pressure ud measured by the sensor 11 in the connection points V3 and V4, in which case then the air pressure sd actually prevailing on the suction side of the compressor 5 results.
  • the variables derived from the compressor map KF, as described with reference to FIGS. 3 and 4, namely the ambient air pressure ud * and the turbine speed nt * can also be used to diagnose the fault of an existing sensor 11, which measures the ambient air pressure ud, or a sensor 13, which the turbine speed nt detected, are used. Such a fault diagnosis can run according to the functional diagram shown in FIG. 5.
  • the subtractor DF is used to determine the offset between the measured ambient pressure ud and the ambient pressure ud * derived from the compressor map or between the measured turbine speed nt and the turbine speed derived from the compressor map nt *.

Abstract

L'invention concerne un procédé selon lequel, à l'aide d'un champ de caractéristiques de compresseur détecté pour un turbocompresseur, lequel indique la relation entre la vitesse de turbine (nt), le rapport entre les pressions d'air (ld, sd) du côté compression et du côté aspiration du compresseur et le courant massique d'air (lm) s'écoulant dans le tuyau d'aspiration, du côté aspiration du compresseur, une de ces grandeurs est dérivée une fois les autres grandeurs données. On fait ainsi l'économie, pour ces grandeurs dérivées, de capteurs correspondants. En outre, lesdites grandeurs dérivées peuvent être utilisées pour le diagnostic des capteurs mesurant les mêmes grandeurs.
