This paper presents the theoretical development of a fuzzy logic based controller for navigation of an Ackermann-like driverless car subjected to kinematic and dynamic constraints in a completely unknown dynamic environment. This controller guides the car from its current position to its end position without any collision with static or dynamic obstacles. Simulation results show the effectiveness of the proposed controller.

“…It flexibly connects the vehicle body and the axles, carries the vehicle body; transmits all vertical forces between body and road, including bears the forces between the tires and body, absorbs the shock from the road surface; protects the vehicle from unwanted vibrations and avoids excessive suspension stroke or related hard stop/impact. The suspension plays a key role in the riding comfort and handling stability [1][2][3]. The primary functions of a vehicle suspension system are to isolate a car body from road disturbances in order to provide good ride quality, to keep good road holding, to provide good handling and support the vehicle static weight [4,5].…”

“…Suspensions generally fall into either of two groups-dependent suspensions and independent suspensions. Suspension systems can be divided into passive suspension, semi-active suspension, and active suspension, according to the different control modes used [1]. There are generally three fundamental elements for a typical vehicle suspension system, including springing, damping, and location of the wheel [6].…”

Abstract. In this paper, a robust passive fault-tolerant control (RPFTC) strategy based on / approach and an integral sliding mode passive fault tolerant control (ISMPFTC) strategy based on / approach for vehicle active suspension are presented with considering model uncertainties, loss of actuator effectiveness and time-domain hard constraints of the suspension system. performance index less than and performance index is minimized as the design objective, avoid choosing weighting coefficient. The half-car model is taken as an example, the robust passive fault-tolerant controller and the integral sliding mode passive fault tolerant control law is designed respectively. Three different fault modes are selected. And then compare and analyze the control effect of vertical acceleration of the vehicle body and pitch angular acceleration of passive suspension control, robust passive fault tolerant control and integral sliding mode passive fault tolerant control to verify the feasibility and effectiveness of passive fault tolerant control algorithm of active suspension. The studies we have performed indicated that the passive fault tolerant control strategy of the active suspension can improve the ride comfort of the suspension system.

“…Traditional, passive suspension design is a compromise between two goalsenhancing the vehicle ride comfort or increasing vehicle stability, because, for example, a small amount of suspension damping will provide a more comfortable ride, but it will significantly reduce the vehicle stability. Thus, the current research focuses on electronically controlled suspensions, which are generally divided into semi-active suspensions and active suspensions [1]. At the same time, many control methods have been applied to active and semi-active suspension systems: preview control, adaptive control, optimal control, nonlinear control, H-infinity control, neural network control and fuzzy logic control.…”

Research of vehicle response to road roughness is particularly important when solving problems related to dynamic vehicle stability. In this paper, unevenness of roads is considered as the source of non-linear vibrations of motor vehicles. The vehicle is represented by an equivalent spatial model with seven degrees of freedom. In addition to solving the response by simulating it within a numerical code, quasi-linearization of nonlinear differential equations of motion is carried out. Solutions of quasi-linear differential equations of forced vibrations are determined using the small parameter method and are indispensable for the study of spatial stability of the vehicle. An optimal stabilization for a simplified two-dimensional model was performed. Spatial stability and internal resonance are considered briefly.
