In this research, fuzzy technique was considered to control an active suspension. The main targets in this study are elimination of the body bounce and pitch in normal ride and roll attitude as well as its bounce resulting from road bumps, on individual tires by using suspension system in both side of car and both axles. In order to have the ability to(More)
A driver-assistance system (DAS) that combines an automatic road departure avoidance (RDA) system with the driver's steering input is presented. The system is based on a closed-loop driver decision estimator (DDE), which establishes the risk of road departure. If a road departure is likely to occur, the RDA system intervenes by correcting the steering(More)

A driving simulator experiment is presented investigating different road departure prevention (RDP) setups. To induce the risk of road departure, thirty test drivers were asked to avoid a pylon-confined area (obstacle) while keeping the vehicle within the road limits. The RDP system intervened by applying a haptic-feedback (i.e., haptic shared control)(More)
The chief purpose of this research is to identify the variable vehicle parameters considering the important role of these data in vehicle active safety systems. Generally, implementing sensors to measure these parameters could raise the cost of the product. Parameters of the reference sedan car we focus on are total mass of the car, yaw moment of inertia(More)
Four wheel steering vehicles are being used increasingly due to high performance and stability that they bring to the vehicles. In this paper a novel high performance four wheel steered vehicle model is considered which is optimally controlled during a lane change manoeuvre in high speeds. The specific configuration of this work is a novel technique for(More)
An integrated vehicle dynamics control system is developed in this paper by a combination of active front steering (AFS) and direct yaw-moment control (DYC) based on fuzzy logic control. The control system has a hierarchical structure consisting of two layers. A fuzzy logic controller is used in the upper layer (yaw rate controller) to keep the yaw rate in(More)
developed in this paper by a combination of active front steering (AFS) and direct yaw-moment control (DYC) based on fuzzy logic control. The control system has a hierarchical structure consisting of two layers. A fuzzy logic controller is used in the upper layer (yaw rate controller) to keep the yaw rate in its desired value. The yaw rate error and its(More)
Media access control (MAC) protocol design is a challenging problem in wireless ad hoc networks. Network resource management like battery life and bandwidth are two design factors in these networks. Some power control MAC protocols try to increase throughput or decrease energy consumption or both of them. We propose a power control scheme based on number of(More)
