Method and apparatus for determining offset-values using a histogram

Values for an output signal in a vehicle sensor are determined. The range of values for the output signal is divided in two sub-areas viz. interval and class. The values for the output signal are allocated to the sub-areas. Numerical ranges are determined to represent the number of values for the output signal allocated to the sub-areas An Independent claim is also included for a device for determining an offset value for an output signal in a vehicle sensor for detecting vehicle movement.
