Quite a lot has been written on active suspension, the topic being suitable for theoretical studies. Unfortunately only a few applicatons have seen the road and even less went into production; by now very few road cars equipped with a real active suspension system are available on the market, and the interest in this kind of application seems to be reduced, perhaps because of high costs and restrictive regulations applied to the race car world. For this reason this paper presents the results of a study conducted on the vertical dynamics of a two wheel car model with a semi active suspension system, a possible alternative to a fully active system to considerably improve suspension performance. Here the damping force of each suspension is obtained by modulating its damping factor according to opportune functions of the system state variables. Thus several of the objectives achievable with a fully active suspension are possible too, without the need for a big amount of energy.
