    Sliding Mode Control of Vehicle Dynamics

    No full text
    The control of the longitudinal, lateral and vertical dynamics of four-wheeled vehicles, both of conventional type as well as fully-electric, is important not only for general safety of vehicular traffic in general, but also for future automated driving. Groups of vehicles can travel more safely with techniques to avoid collisions due to unintended or unexpected movements of one or more members. Sliding Mode Control of Vehicular Dynamics provides an overview of this important topic. Topics covered include an introduction to sliding mode control; longitudinal vehicle dynamics control via sliding modes generation; sliding mode control of traction and braking in two-wheeled vehicles; lateral vehicle dynamics control via sliding modes generation; stability control of heavy vehicles; sliding mode approach in semi-active suspension control; and observer-based parameter identification for vehicle dynamics assessment. Each chapter introduces the problem formulation and a general overview of its physical aspects, provides a survey of the relevant literature on the topic, and reports on the authors' contributions to solving the control problem

    Minimum sensor second-order sliding longitudinal control of passenger vehicles

    In this paper, a minimum sensor variable structure control strategy for cruise and tracking longitudinal control of vehicles has been proposed. It relies on the generation of “secondorder” sliding regimes, i.e., sliding modes characterized by an identically null derivative of the sliding variable. Because of the lack of measurements, the use of suitably designed observers is exploited in the paper. On the whole, the proposed strategy is designed so as to guarantee a bounded jerk and to avoid too frequent changes between the use of the accelerator and the brake. The control strategy is robust with respect to matched bounded parameters variations, and uncertainties
