direct yaw moment control systems (dyc) can maintain the vehicle in the driver’s desired path by distributing the asymmetric longitudinal forces and the generation of the control yaw moment (cym). in order to achieve the superior control performance, intelligent usage of lateral forces is also required. the lateral wheel forces have an indirect effect on the cym and based upon their directions,...

in this article, vehicle cornering stability and brake stabilization via bifurcation analysis has been investigated. in order to extract the governing equations of motion, a nonlinear four-wheeled vehicle model with two degrees of freedom has been developed. using the continuation software package matcont a stability analysis based on phase plane analysis and bifurcation of equilibrium is perfo...

Direct yaw moment control is an effective means to enhance vehicle stability and handling. The majority of the latest direct yaw moment control works employ sliding mode control to generate the target yaw moment. This paper proposes a new sliding mode-based direct yaw moment control method for simultaneous tracking of desired yaw rate and vehicle side-slip for electric and hybrid vehicles equip...

non-linear characteristic of tire forces is the main cause of vehicle lateral dynamics instability, while direct yaw moment control is an effective method to recover the vehicle stability. in this paper, an optimal linear quadratic regulator (lqr) controller for roll-yaw dynamics to articulated heavy vehicles is developed. for this purpose, the equations of motion obtained by the matlab softwar...

Direct Yaw moment Control systems (DYC) can maintain the vehicle in the driver’s desired path by distributing the asymmetric longitudinal forces and the generation of the Control Yaw Moment (CYM). In order to achieve the superior control performance, intelligent usage of lateral forces is also required. The lateral wheel forces have an indirect effect on the CYM and based upon their directio...

The yaw moment control is the most efficient method for improving vehicle handling and stability. A corrective yaw moment should be applied to the vehicle in order to modify the dynamic behaviour of vehicle. This corrective yaw moment is related to the interaction between the tires and road. Therefore generating corrective yaw moment independent from the tire-road interactions is noteworthy. In...

By considering a four-wheel-motor EV, the present paper addresses the EV stabilization using the advantages of electrical motorized wheels incorporation. The decoupling of the control of the active steering control (AFS) and the direct yaw moment control (DYC) as a way of controlling the vehicle’s body slip angle and its yaw rate simultaneously, also allows the stabilization of the lateral moti...

This paper suggests a nonlinear control law to stabilize the rolling motion of missiles. Based on the analysis of rolling moment characteristics due to pitch/yaw control cross-coupling, we propose a conjecture that the moment is described by the bilinear form of pitch/yaw acceleration and yaw/pitch control. The conjecture fits a set of wind tunnel test data and leads to a bilinear control law. ...

Nowadays, using advanced vehicle control and safety systems in vehicles is growing rapidly. In this regard, in recent years new control systems, called VDC, have been introduced. These systems stabilize vehicle yaw motion, by yaw moment resulted from tire controlling forces. In this paper, an adaptive optimal controller applied to a vehicle to obtain a satisfactory lateral and yaw stability. To...

Electric vehicles with independently controlled drivetrains allow torque vectoring, which enhances active safety and handling qualities. This article proposes an approach for the concurrent control of yaw rate sideslip angle based on a single-input single-output (SISO) controller. With SISO formulation, reference is first defined according to vehicle requirements then corrected actual angle. Th...
