Method for determining states of a system by means of an estimation filter, in which first state values are determined by calculating a mean value of a probability distribution for the states, in which a probability for deviation for the case that the first state values deviate from the actual states of the system is calculated, and in which the states of the system are measured as state data. In the method the first state values are corrected by means of the state data then, if the probability for deviation is larger than a threshold.

A method and apparatus for determining positioning information for driver compliance. The apparatus comprising a an electronic processor connected to an electronic control unit and a transceiver and configured to receive the vehicle data from the electronic control unit, determine whether the apparatus includes a local source of positioning information, determine whether a positioning information from the local source of positioning information meets or exceeds an accuracy threshold and an availability threshold, if the apparatus includes the local source of positioning information, and send a request to the portable communication device for additional positioning information if the apparatus does not include the local source of positioning information, or the positioning information from the local source of positioning information does not meet or exceed the accuracy threshold, the availability threshold, or both.

A method for determining load cycles uses a first buffer containing a first value of a physical variable in a first position and a second value thereof in a second position. A measured third value is stored in a third position. A Rainflow filter is applied, it is checked whether a point of inflection results between the first value and the third value. If the second value forms a point of inflection, then the first position is overwritten with the second value, the second position is overwritten with the third value, the second value is discretized and stored as the last entry in a second buffer. If a second-from-last entry and third-from-last entry form a load cycle, then these values are registered in a Rainfall matrix and removed from the second buffer, and the second buffer is again checked for a load cycle.
