Definitions

  • the invention relates to a method for determining a load spectrum for a transmission in motor vehicles according to the preamble of patent claim 1.
  • load spectra ie to determine time-varying loads, usually in the form of vibrations.
  • load spectra for a transmission are determined based on the actual engine torque from the engine control or based on a measured by a torque sensor transmission torque.
  • moments of inertia and moments of inertia of the gear load are not detected.
  • the installation of a torque sensor is complicated and expensive and thus unsuitable for widespread use in the vehicle fleet. It is an object of the invention to develop the method of the type mentioned in such a way that a more accurate determination of the load collective is possible.
  • the transmission torque at the transmission input is calculated continuously from predetermined operating parameters in order to determine the load spectrum. From the continuously calculated gear torque values, a matrix is created in which the frequency of occurrence of a gear torque in a defined gear torque class is entered and stored for each gear.
  • the respective stored values of the matrix are preferably stored in a non-volatile memory at each switch-off operation of the motor vehicle operation.
  • the stored values of the matrix are read out of the non-volatile memory during an on-site visit to the vehicle-external evaluation.
  • This evaluation can preferably be used as a basis for a targeted new transmission development.
  • Fig. 3 shows a comparison of the previously used Motoristmoment and the invention calculated gear torque when changing gear with manual switch for determining a load spectrum
  • Fig. 4 shows a comparison of the Motoristmoment previously used and the invention calculated gear torque when changing gear with automatic transmission and converter to determine a load collective.
  • the engine speed nMot and the actual engine torque MMot are detected or determined in an engine operating parameter function block 1.
  • the rotational speeds of the drive wheels nHA here the rear wheels determined.
  • the rotational speed of the drive wheels nHA is calculated together with the engine speed nMot in a gait determination block 3 to determine the respective current gear.
  • the transmission torque Md is calculated in dependence on the operating parameters MMot, nMot and other operating parameters, which will be discussed in more detail below.
  • the values of the matrix respectively stored in the RAM 6 are stored in each non-volatile operation of the motor vehicle operation (eg "terminal 15 off") in a non-volatile memory 7.
  • the stored values of the matrix for example, at a workshop visit from the non-volatile Memory 7 to the vehicle external evaluation, for example, read by means of a diagnostic tester 8.
  • the functional blocks 1 to 8 for carrying out the method according to the invention can be realized as a new program module in an electronic engine control unit or electronic transmission control unit which is present anyway in any case.
  • engine here is understood to mean a motor vehicle drive motor, such as an internal combustion engine or an electric motor.
  • Gear torque [Nm] actual engine torque [Nm] - moment of inertia_ crankshaft [kgm 2 ] * d (engine speed) / dt [rad / s 2 ]
  • This algorithm is suitable for powertrains with dual mass flywheel (DMF) in the frequency range ⁇ 10 Hz.
  • DMF dual mass flywheel
  • This limit is given on the one hand by the sampling limitation to 100 Hz due to the given CPU power currently used engine control units and on the other hand by the transmission behavior of the ZMS, because the function of the method is guaranteed only in subcritical ZMS operation.

  • This algorithm when implemented in a current engine or transmission control device, allows for the detection of the transmission torque Md at the transmission input after the turbine in the frequency range ⁇ 10 Hz because of the already mentioned sampling limit of 100 Hz due to the given CPU power of currently used engine control devices.
  • 4 shows the comparison of the pure engine actual torque MMot with the gear torque Md calculated according to the invention, which is almost equal to the real gear torque, for an automatic transmission with an open and closed converter clutch and during its closing operation.
  • the quality of the formula results largely depends on the quality and conditioning of the engine signals in the engine control unit.
  • the inertia components for accelerating the crankshaft including the flywheel and the clutch are taken into account.
  • the alternation portion of the transmission load due to the cyclical torque output of the reciprocating engine and due to intrinsic shapes of the drive train, such as jerking, etc. is detected.
  • the torque load of the transmission in the real vehicle can be determined nationwide with high quality based on existing signals from the engine control without additional torque sensors.
  • an exact dimensioning and design of the transmission is possible, which possibly leads to weight reduction and cost savings without sacrificing function and strength.

Abstract

Selon l'invention, le couple d'entraînement à l'entrée de la boîte de vitesse est calculé de façon continue à partir de paramètres opérationnels prédéfinis afin de déterminer l'ensemble des charges d'une boîte de vitesse pour des véhicules automobiles. A partir des valeurs du couple d'entraînement calculées de façon continue, on établit une matrice dans laquelle on inscrit et enregistre, pour chaque vitesse, la fréquence d'apparition d'un couple d'entraînement dans une classe définie de couple d'entraînement. De préférence, les valeurs enregistrées de la matrice sont déposées chacune dans une mémoire non volatile à chaque opération d'arrêt du fonctionnement du véhicule et analysées en dehors du véhicule dans le but de développer de nouvelles boîtes de vitesse.
