Abstract: Systems and methods are provided for detecting the departure of a vehicle from a set of land boundaries. A boundary determination component is configured to determine an associated set of lane boundaries for a vehicle. A kinematic sensor is configured to measure at least one kinematic parameter associated with the vehicle. A lane departure warning system is configured to determine if the vehicle is crossing one of the determined set of lane boundaries from the at least one kinematic parameter and provide a response signal if the vehicle is crossing one of the determined set of lane boundaries.

Abstract: The reliability of a pressure sensor is improved either by utilization of redundant components. A pair of pressure sensors are mounted upon a single pressure sensor diaphragm. Each of the pressure sensors is connected to one of a pair of signal conditioning circuits. The gain of one of the signal conditioning circuits is a fraction of the gain of the other signal conditioning circuit. The outputs of each of the signal conditioning circuits are compared to a corresponding threshold. If both of the output signals exceed the corresponding threshold, it is determined that a malfunction of the pressure sensor has occured.

Abstract: The reliability of a pressure sensor is improved either by utilization of redundant composants. A pair of pressure sensors are mounted upon a single pressure sensor diaphragm. The pressure signals generated by the pressure sensors are compared and, if the difference between the signals exceeds a predetermined threshold, it is determined that a malfunction of the pressure sensor has ocurred. Alternately, additional diagnostic testing may be included to detect a malfunctioning sensor.
