Abstract

A pressure sensor module for a vehicle includes a sensing element module, a sampling module, a filtering module, and a monitoring module. The sensing element module measures a pressure of a fluid and outputs a pressure signal based on the pressure. The sampling module samples the pressure signal. The filtering module receives at least one filter coefficient from a control module and determines a filtered pressure based on at least one of the samples. The monitoring module receives a condition monitoring request from the control module, receives a predetermined value from the control module, and notifies the control module when a condition is satisfied based on a comparison of the predetermined value and one of the filtered pressure and a parameter determined based on the pressure signal.
