Roll angle plausibility detection

摘要

A vehicle safety system (20) includes a controller (24) that verifies the plausibility of a roll angle indication obtained by processing a roll angular rate sensor (26) output. The controller (24) determines whether an acceleration value corresponding to the roll angle indication is within an expected range. In a disclosed example, the controller (24) utilizes a vertical acceleration value and a first expected range and a lateral acceleration value and a second expected range. When both of the acceleration values are outside of the respective expected range, the controller determines that the roll angle indication is invalid.
