The vehicle control system based on Network communication becomes increasingly complicated recently. The traditional research only focuses on the improvement of network communication quality or system control performance. The network configuration had been carried out to study the vehicle chassis integrated control system. Based on the MATLAB/Simulink and TrueTime Toolbox, the distributed CAN network...
This paper deals with a hierarchical architecture of the Engine Control Unit (ECU) made-up of two levels: the higher one, called powertrain level, computes the current and the future torque demands; The lower level, called engine level, uses these information to provide an appropriate motor control. In continuous-time framework, a H2-control design with preview is proposed for the lower level and...
The control of car following is essential to its safety and its operational efficiency. For this purpose, this paper builds a linear, continuous and time-delay model of car following. And then, presents a controller based on an adaptive network fuzzy inference system (ANFIS) for the car-following collision avoidance system to adaptively control the speed of the vehicle. The relative distance and relative...
The safety and comfort control of vehicles in certain cases is considered in this paper. We hope to use detectors plus advanced control methods to realize the satisfactory tracking control, even the proper velocity and acceleration control of vehicles. Because of the intrinsically nonlinear, highly plant uncertain of vehicles and closely interconnected among vehicles, here the method based on the...
This brief investigates the problem of robust sampled-data H∞ control for active vehicle suspension systems. By using an input delay approach, the active vehicle suspension system with sampling measurements is transformed into a continuous-time system with a delay in the state. The transformed system contains non-differentiable time-varying state delay and polytopic parameter uncertainties. A Lyapunov...
In this article we study a two-level driver model composed of one anticipatory and one compensatory control. The anticipatory control, executed in an open loop, is based mainly on the standard linear equations for the lateral dynamics of the vehicle. The compensatory control, executed in a closed loop, uses N PID controllers for the correction of lateral deviation, and other N PID controllers for...
In this paper, a decentralized overlapping static output feedback law is proposed to control a linear time-invariant (LTI) interconnected system. It is assumed that an overlapping information flow structure is given which determines which output measurements are available for any local control agent. Uncertain transmission delay is also considered in communication links among different subsystems...
This paper considers a design problem of controllers for our developed networked control system based on state predictive control. Our developed system consists of a wireless vehicle, a router in a computer network and a computer as the controller. Because the router has an AQM mechanism to keep the queue size constant, our networked control system can be described as linear systems with an input...
The work in this paper focuses on stabilization in the presence of delayed and intermittent communication in the coordinated control of multiple vehicles. Without prediction of the system evolution during the communication and sensing delays, an alternative to the design of stabilizing controllers based on state gain selection is constructed. The technique consists of an abbreviated zero order hold,...
In this paper an active brake control to reduce the rollover risk of heavy vehicles is proposed. The brake system is activated when the vehicle comes close to rolling over. In order to enhance the performance of the active brake, the braking algorithm is extended with an estimation procedure of the side force coefficient in order to use it in control. The estimated value of the side force coefficient...
