Abstract:
A rough road detection system for a vehicle comprises a first acceleration sensor that measures vertical acceleration of a component of the vehicle. An adaptive acceleration limits module determines a first acceleration limit based upon a speed of the vehicle. A limit comparison module generates a rough road signal based on a comparison of the first acceleration limit from the adaptive acceleration limits module and the measured acceleration from the first acceleration sensor.
