  • Patent number: 9330061
    Abstract: Method and control device for determining a steering angle of a motor vehicle, wherein a theoretical steering angle is calculated by a vehicle model and a measured steering angle is determined with a steering angle sensor, and the difference between the measured and theoretical steering angles is determined, wherein at least one data record including a number of successive measured values is acquired, and a correction constant for the measured steering angle is determined from the mean value of the differences between the theoretical steering angle and the measured steering angle. According to the invention, a confidence level, which changes incrementally between successive data records, is calculated by travel conditions present during the acquisition of the data record and/or an analysis of the data record.

  • Patent number: 8509994
    Abstract: In a method for determining a steering angle for a vehicle, a steering angle is determined using a single-track model of the vehicle, wherein the steering angle is corrected only if the difference between the derivative of a measured steering lock angle and the derivative of a calculated steering lock angle is below a threshold value. Otherwise the measurement is repeated.

  • Patent number: 7920981
    Abstract: The invention relates to a method of calibrating a sensor, in particular a yaw rate sensor, in which sensor values (Ysensor) and associated temperature values (T) are stored in the shape of reference points in a non-volatile memory of the sensor, in which case the values (Ysensor, T) are determined during a calibration mode in which the sensor is exposed to a predefined temperature profile. In order to further improve the accuracy of the calibration, the invention discloses that the values (Ysensor, T) determined in the calibration mode are used to determine coefficients (C0, . . . , Cn-1, Cn) of a polynomial of nth order, and these coefficients are stored.

  • Publication number: 20070208524
    Abstract: A method serves to compensate the offset of a sensor signal, in particular of an acceleration sensor detecting movements in the driving direction of a vehicle (longitudinal acceleration sensor). The offset of the signal during the lifetime of the vehicle adapted by means of a long-duration offset filter (LZOF). More particularly, the measuring signal for determining the offset, preferably, is not filtered in response to time but in response to travel.

  • Patent number: 6625527
    Abstract: A sensor system with monitoring device wherein the sensor system includes at least two redundant sensors for gathering a process reference variable or process measured variable of a process, and in that the monitoring device includes a first subtractor for producing a first difference between the sensor output signals, a first and a second differentiator for the time derivative of the sensor output signals, a second subtractor for producing a second difference between the differentiated sensor output signals, and a fault analysis device by which the first and the second difference is respectively compared with a predeterminable first or second threshold value, and a fault message is produced when at least one of the differences exceeds the threshold value concerned.
