Definitions

  • the invention relates to a method for checking the plausibility of a parameter which is included in the operation of a vehicle system of a motor vehicle, wherein the parameter detected by a first sensor is checked for plausibility with a second sensor which also detects the parameter by checking a first sensor signal of the first sensor with a second sensor signal of the second sensor.
  • the invention further relates to a control device, a computer program product and a data carrier.
  • Vehicle systems are usually provided for motor vehicles to support a driver when operating the respective motor vehicle.
  • a vehicle system also intervenes in the actual operation as a safety system in order to avoid critical operating states by executing safety functions or to ensure safe operation of the motor vehicle in the event of malfunctions.
  • a regulation or control of such a safety function usually takes place on the basis of parameters that are recorded by corresponding sensors in the motor vehicle.
  • sensors can also fail or transmit incorrect information, which would also result in incorrect execution of the respective safety function, reliable operation of the sensors must also be monitored when operating a safety system in a motor vehicle.
  • DE 10 2005 048 015 A1 describes a method for checking the plausibility of a parameter, whereby the method can be used in a vehicle system of a motor vehicle, such as an ESP system, an airbag system, a driver assistance system (ACC) or similar.
  • a parameter is determined which is necessary for carrying out a control or regulation of a respective function of the vehicle system
  • DE 10 2005 048 015 A1 also specifies redundant monitoring as a possibility, in which a sensor signal from one sensor is checked using a different sensor signal.
  • the object of the present invention is to design a plausibility check of a parameter in the simplest and at the same time most reliable manner possible.
  • a method is used to check the plausibility of a parameter which is included in the operation of a vehicle system of a motor vehicle.
  • the parameter detected by a first sensor is checked for plausibility with a second sensor which also detects the parameter by checking a first sensor signal of the first sensor with a second sensor signal of the second sensor.
  • the parameter is therefore detected by a first sensor and a second sensor, whereby the parameter is determined from a first sensor signal of the first sensor and checked for plausibility using the second sensor.
  • the first sensor signal of the first sensor is checked against a second sensor signal of the second sensor.
  • Both sensors are used to directly record the parameter, whereby these recordings are preferably carried out independently of each other for the purpose of plausibility.
  • the two sensors are each provided in a corresponding area, for example both directly on a component on which the parameter can be directly recorded.
  • the invention now includes the technical teaching that the check is carried out by forming a difference signal between the first sensor signal and the second sensor signal and comparing it with at least one threshold value. A measure is then carried out if the difference signal exceeds the at least one threshold value continuously for longer than a period of time associated with the at least one threshold value.
  • the first sensor signal is checked against the second sensor signal by creating a signal as the difference between the first sensor signal of the first sensor and the second sensor signal of the second sensor, with this difference signal then being compared with at least one threshold value. If the difference signal exceeds the at least one threshold value, a measure is started if the threshold value is continuously exceeded and after the elapse of a period of time associated with the threshold value.
  • the procedure according to the invention has the advantage that it enables the plausibility of the parameter to be checked in a simple and at the same time reliable manner. This is because by forming the difference signal and comparing this difference signal with the at least one threshold value, it is possible to check whether there is a deviation between the detection of the parameter via the first sensor and the detection of the parameter via the second sensor of a magnitude that indicates an inconsistency in the detection, for example an incorrect measurement or even a defect in one of the sensors or a defect in a cable. Even if the at least one threshold value is exceeded by the difference signal, a measure is only initiated if the at least one threshold value is continuously exceeded for longer than a predetermined period of time that is assigned to the at least one threshold value.
  • the respective time period thus represents a corresponding filter time.
  • the difference signal is compared with a first threshold value and a second threshold value, the measure being carried out when the difference signal either exceeds the first threshold value continuously for longer than a first period of time associated with the first threshold value duration or the second threshold value is continuously exceeded for longer than a second duration associated with the second threshold value.
  • different conditions can advantageously be defined for initiating the measure by assigning a suitable threshold value with a suitable duration to the respective condition.
  • the second threshold value was selected to be greater than the first threshold value and the first time period was selected to be greater than the second time period.
  • the measure can also be carried out using the second threshold value and the associated second time period if larger deviations between the sensor signals are detected, although these larger deviations do not have to last as long as the first threshold value and the first time period. For example, this can be used to detect a defect in a cable or something similar.
  • the comparisons of the difference signal with the first threshold value and the second threshold value are carried out in parallel. This has the advantage that if one of the threshold values is exceeded for a correspondingly long period of time, the measure is initiated immediately.
  • the comparisons can also be carried out consecutively by first comparing the difference signal with the first threshold value or first comparing the difference signal with the second threshold value.
  • a request for emergency operation is generated as a measure in which safe operation of the motor vehicle is carried out. If it is detected that the difference signal exceeds the at least one threshold value continuously for longer than the time period assigned to the at least one threshold value, the system switches to emergency operation in which safe operation of the motor vehicle is guaranteed in any case. is guaranteed.

Abstract

L'invention concerne un procédé de contrôle de la vraisemblance d'un paramètre impliqué dans le fonctionnement d'un système de véhicule d'un véhicule automobile, la vraisemblance du paramètre détecté par un premier capteur étant contrôlée au moyen d'un second capteur, qui détecte également le paramètre, par l'examen d'un premier signal de capteur (n(S1)) en provenance du premier capteur avec un second signal de capteur (n(S2)) en provenance du second capteur. Afin de rendre le contrôle de la vraisemblance aussi fiable que possible, un signal différentiel (Δn) entre le premier signal de capteur (n(S1)) et le second signal de capteur (n(S2)) est formé et comparé à au moins une valeur de seuil (thd1, thd2). Une mesure est effectuée si le signal différentiel (Δn) dépasse ladite valeur de seuil (thd1, thd2) en continu pendant une durée supérieure à une durée particulière (tft1, tft2) associée à ladite valeur de seuil (thd1, thd2).
