Abstract

Die Erfindung betrifft ein Verfahren zum Steuern der Energieversorgung eines Kraftfahrzeugmotors, bei dem in Abhängigkeit von der Abweichung zwischen dem jeweils aktuellen Betriebszustand des Fahrzeugs und einem gewünschten Betriebszustand Steuersignale (Xn) unter Berücksichtigung von Signalen mindestens zweier ein Steuerelement (5,8) überwachender Sensoren (S1,S2,S3,S4) an ein Stellglied (5) abgegeben werden, welches die Energieversorgung des Kraftfahrzeugmotors steuert, wobei im Fall einer Störung des Signals eines der Sensoren (S1,S2,S3,S4) das ungestörte Signal des jeweils anderen Sensors (S1,S2,S3,S4) zur Ermittlung der an das Stellglied (5) abgegebenen Steuersignale solange benutzt wird, bis die durch das ungestörte Signal angegebene gewünschte Veränderung des Betriebszustandes einen auf den jeweiligen Betriebszustand bezogenen Grenzwert (P(g),R(rpm,g)) überschreitet, und wobei im Fall des Überschreitens des Grenzwertes (P(g),R(rpm,g)) die Steuersignale (Xn) für das Stellglied (5) nach Art eines PI-Reglers bestimmt werden, wobei der Startwert (iT0) für den Integralanteil (iTn [n=0...m]) der Regelung gleich einem Anfangswert (R) bestimmt wird, welcher dem Betriebszustand des Fahrzeugs zum Zeitpunkt des Überschreitens zugeordnet ist.

Figure 00000001
The invention relates to a method for controlling the energy supply of a motor vehicle engine, in which, depending on the deviation between the current operating state of the vehicle and a desired operating state, control signals (X n ) taking into account signals from at least two sensors monitoring a control element (5, 8) (S1, S2, S3, S4) to an actuator (5) which controls the energy supply of the motor vehicle engine, wherein in the event of a fault in the signal of one of the sensors (S1, S2, S3, S4) the undisturbed signal of the other Sensor (S1, S2, S3, S4) is used to determine the control signals output to the actuator (5) until the desired change in the operating state indicated by the undisturbed signal is a limit value (P (g), R (rpm, g)), and if the limit value (P (g), R (rpm, g)) is exceeded, the control signals (X n ) for d he actuator (5) can be determined in the manner of a PI controller, the start value (iT 0 ) for the integral component (iT n [n = 0 ... m] ) of the control being determined equal to an initial value (R) which corresponds to the Operating state of the vehicle is assigned at the time of exceeding.
