increased competition on the automotive market has forced companies to research alternative strategies to classical passive suspension systems. In order to improve handling and comfort performance, instead of a conventional static spring and damper system, semi-active and active systems are being

In this paper, we demonstrate a novel hybrid control synthesis approach using an automotive suspension system. Discrete abstractions are used to approximate the continuous dynamics and emphasis is placed on the nondeterministic nature of the abstracting models. The regulator problem for hybrid systems is formulated for safety specifications and algorithms for control design are presented.

This paper proposes a novel approach to the verification of hybrid systems based on linear and mixed-integer linear programming. Models are described using the Mixed Logical Dynamical (MLD) formalism introduced in [5]. The proposed technique is demonstrated on a verification case study for an automotive suspension system.

This paper reviews recent automotive applications of sliding mode control. The design methods discussed include sliding mode optimization, integral sliding mode and higher order sliding mode. Examples of applications of conventional sliding mode as well as advanced techniques in vehicle suspension control, engine throttle position control, parameter estimation and fault diagnosis are summarized.

The estimation of road excitation profile is important for evaluation of vehicle stability and vehicle suspension performance for autonomous vehicle control systems. In this work, the nonlinear dynamics of the active automotive system that is excited by the unknown road excitation profile are considered for modeling. To address the issue of estimation of road profile, we develop an adaptive sup...

In paper, the virtual prototype of the rolling – guiding – suspension system of an off-road vehicle is presented. The prototype has been made with the MBS software ADAMS, and takes into consideration the geometric restrictions as well as the nonlinear characteristics of the elastic and damping elements. The experiment designed is one frequently carried by the automotive manufacturers, namely dy...

Automobiles are required to be even lighter for further achieving environmental protection through fuel economy improvement, as well as safety feature enhancement and drivability improvement. Automotive suspensions are also required to reduce their weight and thus more aluminum is being adopted. Aluminum forgings, in particular, are often applied because of their significant weight reduction ef...
