Definitions

  • the invention relates to a method for regulating the pressure in a fuel reservoir of an internal combustion engine, in particular a common rail system. Moreover, the invention relates to a computer program and an apparatus for carrying out this method.
  • Such a method and apparatus are basically known. More specifically, this document teaches to provide at least first and second control circuits for regulating the pressure in a fuel tank.
  • a first control mode only the first control loop is used to regulate the pressure, wherein the pressure in the fuel accumulator is controlled by suitable control of a high pressure pump as a pressure control means.
  • a second control mode is provided in which the pressure control takes place with the aid of the second control circuit via a pressure control valve, which acts directly on the fuel tank.
  • the first or second control mode used for pressure control.
  • a switching process takes place from the first to the second control mode when certain values for the rotational speed or the fuel quantity to be injected are exceeded in a specific operating state of the internal combustion engine.
  • suitable criteria are defined for the complementary switching from the second to the first control mode.
  • WO 03/046357 A1 describes a method for controlling an internal combustion engine, in which a controlled system for regulating the rail pressure at a detected faulty rail pressure sensor separated and transferred to a controlled emergency operation. During the transition phase to controlled emergency operation, the control deviation is specified by a transition function. Based on this prior art, it is therefore an object of the invention to develop a known method for regulating the pressure in a fuel storage of an internal combustion engine and a known computer program and a known device for performing this method such that the course of the rail pressure during a switching between two different control modes are not disturbed in an unacceptable way.
  • This object is achieved by the method claimed in claim 1.
  • This method is characterized in that for carrying out the switching operation involved in the switching control loops are opened by their control devices are controlled instead of the previous input signal for preferably preferably each switching individually predetermined Umschalteingangssignalen, which are designed so that the control devices in the desired manner from a current operating state defined by the current control mode to one by the future control mode defined future operating state.
  • This claimed procedure for performing a switching from a current control mode to a future control mode has the advantage that undesirable disturbances of the rail pressure during the switching operation are avoided. According to the invention, this takes place in such a way that the control circuits involved in the switching operation are continuously transferred from their activated or deactivated operating state during the current control mode into their new activated or deactivated operating state during the future control mode by the switching input signal.
  • the switching input signal advantageously represents individually suitable control values for each switching cycle.
  • a control loop which changes in the context of a switching from an activated to a deactivated operating state or vice versa, opened to perform the switching, that is, the control loop is separated for the duration of the switching operation.
  • the control device of the separated control loop is then no longer operated with the input signal but with the switching input signal, wherein the control value represented by the switching input signal is at least approximately adapted to the last control error supplied to the control device. In this way, a smoother as possible or more homogeneous Transition from the current control mode into the switching process ensured.
  • the switching control signal is formed from the predetermined control values and a rail pressure deviation applied thereto.
  • This rail pressure deviation causes a correction of the fixed predetermined control values with respect to a current pressure situation in the fuel tank 200, wherein depending on the magnitude and sign of this pressure deviation, the speed at which the pressure in the fuel tank 200 is controlled, in view of the current there Drucksituaticn positive being affected.
  • the connection of the rail pressure control deviation also causes the pressure deviation caused by the switching process in the fuel storage 200 to be kept as low as possible.
  • transitions between steady-state control operation and switching operation are further smoothed or homogenized in both directions by monitoring a shift in the operating point caused by the switching input signal during at least that control device which switches from an activated to a deactivated operating state during the switching process reversed changes. It is then advantageous for homogenization purposes, if the transition from the switching operation in the future control mode is actually only carried out by disconnecting the switching input signal and clamping the usual input signal to the regulator device, if at least the monitored control device provided her for the future control mode activated or has reached deactivated operating state.
  • control devices of the two control circuits are each fed with an input signal which not only the control loop associated with the control error, but also the represents a control deviation assigned to each other control loop.

  • the first control circuit ensures that precisely the amount of fuel which is predetermined via a setpoint signal S M-setpoint of the subtraction unit 112 is supplied to the high-pressure pump 210 via the throttle valve 116.
  • the difference formation device 112 performs a constant comparison between the desired fuel quantity requested by the desired quantity signal S M-desired and the flow rate through the throttle valve 116 actually provided and represented by the is-quantity signal S M-ist actual fuel quantity and outputs a possibly detected difference r1 between the target and the actual amount as a quantity deviation.
  • This quantity deviation r1 is output to the control device 114 during steady-state operation of the first control loop as a control deviation in the form of an input signal e1.
  • the amount of fuel actually metered in by the throttle valve 116 in accordance with FIG.
  • the first control circuit 110 initially controls only the fuel quantity supplied to the high-pressure pump 210.
  • the high-pressure pump 210 is connected to the fuel storage 200 via a fuel line 220.
  • the control of the amount of fuel supplied to the fuel reservoir 200 by means of the first control circuit can therefore indirectly also control the pressure in the fuel accumulator.
  • a second control circuit 120 In addition to the first control loop, the device 100 according to FIG. 1 Furthermore, a second control circuit 120. This includes a second difference formation device 122, which a possible deviation between a predetermined target pressure, represented by a signal S D target and that of one.
