A method for controlling four semi-active suspensions of a vehicle comprising the steps of: determining, for each semi-active suspension, a first and a second signal representative of the acceleration and speed of the sprung mass; determining, for a pair of semi-active suspensions arranged on one side of the vehicle a third and a four signal representative of the acceleration and pitch speed; calculating for each semi-active suspension, a first damping coefficient as a function of the difference between the first and second signal squared; calculating for each semi-active suspension, a second damping coefficient as a function of the difference between the third and the four signal squared; for each semi-active suspension, comparing the first and the second damping coefficient for determining the higher coefficient; ; applying to each force generator device, an electronic control signal indicative of the respective high damping coefficient.

Abstract

A method for controlling four semi-active suspensions of a vehicle comprising the steps of: determining, for each semi-active suspension, a first and a second signal representative of the acceleration and speed of the sprung mass; determining, for a pair of semi-active suspensions arranged on one side of the vehicle a third and a four signal representative of the acceleration and pitch speed; calculating for each semi-active suspension, a first damping coefficient as a function of the difference between the first and second signal squared; calculating for each semi-active suspension, a second damping coefficient as a function of the difference between the third and the four signal squared; for each semi-active suspension, comparing the first and the second damping coefficient for determining the higher coefficient; ; applying to each force generator device, an electronic control signal indicative of the respective high damping coefficient.
