Abstract
A vehicle suspension system () includes a suspension (). A lateral acceleration sensor () generates a lateral acceleration signal. A roll rate sensor () generates a roll rate signal. A controller () detects an irregularity in the suspension in response to the lateral acceleration signal and the roll rate signal. A method of detecting suspension irregularities in a vehicle () includes the generating of a lateral acceleration signal and a roll rate signal. Roll angle is determined in response to the lateral acceleration signal and roll rate signal. A roll gradient, a roll acceleration coefficient, and a roll damping parameter are determined in response to at least the roll angle. The roll gradient, the roll acceleration coefficient, and the roll damping parameter are compared to associated nominal values. A suspension irregularity is indicated in response to the comparison.
