Abstract:
1. A method of estimating values outside of sensor limits comprising the steps of: a. determining an actual slope from measured data values indicative of vehicle operation within sensor limits; b. determining an estimated slope based on the actual slope; c. estimating data values outside of the sensor limit based on the estimated slope, wherein the estimated slope is determined as a percentage of the actual slope that is less than 100% of the actual slope and the estimated data values are determined until an actual measured data value fails within sensor limits, d. indicating a first condition in response to the measured data value being within a first range within the sensor limits; e. indicating a second condition in response to the estimated data value being within a second range outside of the sensor limits; and f. transmitting a signal indicative of one of the first and second conditions for use by a system.
