ABSTRACT:
A system for detecting hazardous conditions during operation of a vehicle. In one embodiment, the system includes a plurality of sensors that monitor a plurality of conditions and transmit condition signals each representing a measure of a condition. A plurality of rate determination circuits is coupled to the sensors and continually receives the condition signals, wherein each rate determination circuit calculates rates of change for the condition, including a baseline rate of change, and outputs a potential hazard value representing a deviation of a rate of change from the baseline rate that exceeds a predetermined threshold value. An evaluation circuit receives the potential hazard value, calculates a new potential hazard value using the potential hazard value and a rate of change for at least one associated condition and determines whether an actual hazard exists by comparing the new potential hazard value with a stored value that corresponds to the condition.
