System for sensing vehicle global and relative attitudes using suspension height sensors

摘要

A control system (18) for an automotive vehicle includes a lateral acceleration sensor (32), a yaw rate sensor (28), a longitudinal acceleration sensor (36), and suspension height sensors (50a-50d). The controller (26) determines a roll characteristic from the first angular rate signal, the suspension height signal, and the lateral acceleration signal and a pitch characteristic from the first angular rate signal, the suspension height signal and the longitudinal acceleration signal.
