Control method of an active suspension of a car
First Claim
1. A control method for an active suspension of a vehicle, the control method comprises the steps of:
- cyclically determining an optimal camber angle of the active suspension; and
driving the active suspension in order to confer the optimal camber angle to the active suspension;
wherein the step of determining the optimal camber angle comprises the further steps of;
determining a slip angle (α
) of a wheel of the active suspension;
determining a vertical force (Fz) weighing on the wheel of the active suspension;
determining a transverse force (Fy) which is transferred to the ground by the wheel of the active suspension; and
determining the optimal camber angle as a function of the transverse force (Fy) which is transferred to the ground by the wheel of the active suspension,wherein the transverse force (Fy), which is transferred to the ground by the wheel of the active suspension, is estimated as a function of the slip angle (α
) of the wheel of the active suspension and as a function of the vertical force (Fz) which weighs on the wheel of the active suspension.

Abstract
A control method for an active suspension of a vehicle, wherein the determination of an optimal camber angle of the active suspension includes the steps of: estimating the slip angle of the wheel of the active suspension; estimating the vertical force which weighs on the wheel of the active suspension; estimating the transverse force which is transferred to the ground by the wheel of the active suspension as a function of the slip angle of the wheel of the active suspension and as a function of the vertical force which weighs on the wheel of the active suspension; and determines the optimal camber angle as a function of the transverse force which is transferred to the ground by the wheel of the active suspension.
