Definitions

  • the invention relates to a method for operating an internal combustion engine of a vehicle, in which by means of sensors and a drive control engine characteristics, in particular the position of pistons in individual cylinders and the speed are determined, wherein an electric motor (electric motor) with the internal combustion engine is coupled.
  • the invention further relates to a computer program product, a control for a drive of a vehicle and a maintenance device with a display and an interface to the controller.
  • An internal combustion engine draws in ambient air with open inlet valves per cylinder, adds fuel to the subsequently compressed ambient air and ignites the fuel-air mixture. In the gasoline engine this is done with the help of a spark.
  • the diesel engine is able to ignite the fuel-air mixture independently.
  • the internal combustion engine is coupled to an electric motor, which can simultaneously serve as a generator for generating electrical energy for the electric power network of a vehicle. It is known to control the internal combustion engine of a vehicle by means of a drive control and sensors coupled thereto. The drive control determines when starting the position of the piston in the individual cylinders and knows the speed of the engine.
  • the internal combustion engine must be free from mechanical damage or high wear in the best possible functional condition, firstly to be able to suck in ambient air and second, in order to be able to compress it.
  • DE 102 36 617 A1 describes a method for operating an internal combustion engine, in which the pressure in a combustion chamber of at least one cylinder is detected at least temporarily during operation of the internal combustion engine by means of a pressure sensor.
  • the maximum value of the pressure in the combustion chamber of the cylinder is determined, which occurs during a power stroke in which the cylinder is not working. The cylinder does not work in the starting phase, in pure overrun mode and cylinder deactivation due to low power demand.
  • the object of the invention is to develop a method, a computer program, a control and a maintenance device of the type mentioned above such that a "health status", in particular a compressibility, of the internal combustion engine can be ascertained quickly, simply and advantageously, already during vehicle operation.

  • the inventive method has the advantage that expensive pressure sensors in combustion chambers are not necessary.
  • the problems arising from the provision of pressure sensors in combustion chambers, such as shielding the pressure sensors from the heat in the combustion chambers and an additional sealing of the pressure sensors in each combustion chamber thus completely eliminated. Since a modern drive control for a combustion engine is torque guided, accurate engine characteristics of the engine such as speed and torque of the drive control are known. Torque-guided means that the driver, upon actuation of the accelerator pedal, detects a requested torque on the drive control, as a result of which the internal combustion engine is controlled.
  • the stored reference values can for example be specified individually for each vehicle in the production process and factory-adjusted to individual manufacturing tolerances.
  • the diagnostic procedure can either execute the drive control itself or a higher-level control.

The prerequisite is that the controller of the electric machine can provide information about the speed and the torque in an interface.

This determines the state of health of each individual cylinder.
  • the actual values of the electric motor are read out when the internal combustion engine is idling or the vehicle is at a standstill and no torques are delivered to the drive wheels. At idling, the measurement result can be determined more accurately, since, firstly, any rotational speeds can be set for the purpose of diagnosis and, secondly, torque-reducing elements, such as the drive wheels, less distort the torque to be measured.
  • the torque values of the electric motor can be read out in an operating state in which the internal combustion engine without fuel injection from the electric motor, in particular at an idling speed, is towed.

  • an electronic evaluation of the electric motor with a more sensitive range than for the operating condition when the electric motor works as a generator is formed. It is understood that the electric motor that tows the internal combustion engine works as a starter.
  • the electric motor can either be designed as a single machine with two functions, ie working as a starter and generator, or the electric motor can also include two machines, one is exclusively intended for generator operation and at least one other works as an electric motor and the Combustion engine starts or supports the combustion engine in a hybrid operation.
  • the diagnostic method is not executed each time when starting the internal combustion engine in a vehicle, but the diagnostic method is performed in special situations, in particular at equal intervals in terms of time and / or with respect to a same distance traveled. Such intervals are known, for example, for other in-vehicle equipment such as changing engine oil or calibrating tachometers, etc.
  • the intervals for carrying out the diagnostic procedure can be shortened should errors in the compression behavior of the internal combustion engine occur.

  • a controller in particular by a hybrid drive controller, which switches off and / or releases certain functions on the drive or drive train during the measurement of the torque values of the electric motor.
  • the method is implemented in a vehicle with hybrid drive.
  • This has the advantage that in a vehicle with hybrid drive substantially all components are present and the method requires no significant additional components, but only by a computer program product that runs in a controller, can be realized.
  • a hybrid vehicle includes an electric machine whose operating characteristics are known to a controller since the electric machine and the internal combustion engine are controlled by a moment coordinator of a hybrid drive controller to jointly or alone provide certain torques at particular driveline speeds.
  • the compression torque of a coupled internal combustion engine can be determined. For example, in a start-stop phase, in which the electric machine rotates the stopped internal combustion engine via a separating clutch to idle speed of the internal combustion engine and the transmission in the drive train is selected to be neutral or disengaged, so that no adhesion to the drive wheels exists and the vehicle is stationary.
  • a compression loss can occur due to a leaky cylinder-piston mating. So that engine oil is sucked in and burned or the air-fuel mixture gets into the crankcase.

Abstract

L'invention concerne un procédé de fonctionnement d'un moteur à combustion interne (1) d'un véhicule, dans lequel des paramètres de moteur, en particulier la position des pistons (20) dans les différents cylindres et la vitesse de rotation, sont déterminés au moyen de capteurs et d'une commande d'entraînement (6), un moteur électrique (machine électrique) (4) étant couplé au moteur à combustion interne (1). L'invention a pour but de constater rapidement et simplement pendant le fonctionnement du véhicule, une aptitude au fonctionnement du moteur à combustion interne, en particulier la capacité de compression du moteur à combustion interne (1). A cet effet, des valeurs instantanées déterminées à partir des paramètres de fonctionnement de la machine électrique (4) sont définies en tant que procédé de diagnostic et évaluées de manière synchronisée avec les paramètres de moteur. Les valeurs instantanées sont comparées aux valeurs de référence enregistrées et si les valeurs instantanées se situent en dehors d'une plage acceptable fixée, on en conclut que le comportement de compression comporte des erreurs.
