摘要:
The invention proposes a method for identifying unstable driving states, wherein the method comprises the following steps: a) detecting whether the magnitude of a difference between a first value of a driving state variable, which value is detected by means of a first sensor, and a second value of the driving state variable, which value is calculated from measured values of at least one further sensor, increases over time, b) filtering the difference by means of a delay element after it has been established that the difference has increased, c) comparing the filtered difference and the unfiltered difference, d) establishing the presence of an unstable driving state when the comparison shows that a deviation between the filtered difference and the unfiltered difference exceeds a predefined threshold value. The method enables an unstable driving state to be identified even when a driving state variable has an offset error which is of the desired size.

Method for determining a value of a defined reference point of a first variable which is measured using an incrementally measuring sensor of a motor vehicle. The method is characterized in that intermediate values of the defined reference point are determined in at least two detection modules using at least one second measured variable, wherein each detection module is matched to the determination of the value of the defined reference point of the first variable in a predefined driving situation, a quality level is determined for each intermediate value determined, the quality levels of the intermediate values determined are compared and the value of the defined reference point is determined from the intermediate values determined in accordance with the result of the comparison of the quality levels. The invention also relates to a device which is suitable for carrying out the method.

The invention relates to a method for controlling a process, according to which an actuation parameter is formed in accordance with a control deviation that is determined by comparing a set-point value with a real value of a control variable. The inventive method is characterized in that the real value of the control variable is determined based on a first process model while it is additionally verified whether there is a need for control (10) by determining control needs (20, 30, 40) based on values of the control variable, which are identified by means of additional process models, and associating said control needs (20, 30, 40) with each other by means of logic operations.
