The wheel driving torque on four-wheel-drive electric vehicles (4WDEVs) can be modulated precisely and continuously, therefore maneuverability energy-saving control carried out at the same time. In this paper, a distribution strategy is developed based multi-objective optimization to improve vehicle reduce energy consumption. high-layer of presented method, sliding mode used calculate desired yaw moment due model inaccuracy parameter error. low-layer, mathematical programming with penalty...
A hierarchical control algorithm of direct yaw moment for four-wheel independently actuated (FWIA) electric ground vehicles is presented. Sliding mode adopted to yield the desired in higher layer due possible modeling inaccuracies and parametric uncertainties. The conditional integrator approach employed overcome chattering issue, which enables a smooth transition proportional + integral-like controller, with antiwindup, when system entering boundary layer. lower level given allocate four...
The sliding mode observer can be used to gather vehicle state information precisely and timely, therefore maneuverability energy-saving control carried out at the same time. In this paper, a based on seven degree of freedom model (7Dof-based observer) improves observation accuracy information. An optimized acceleration feedback (Accelerometer-based reduces error under tire nonlinear adhesion limit conditions. proposed observers could reduce calculation cost, optimization results are sent...
In order to solve the problem of no power coupling in independent driven vehicle, liquid viscous (LVC) has been chosen from several couplings.The performance characteristic LVC and vehicle steering have analyzed, for target designed.Then lateral simulation with conducted.The results show that used as bad effect on performance, handling stability improved.
The simulation of electronic control function failure has been utilized broadly as an evaluation method when determining the Automotive Safety Integrity Level (ASIL). driver model is quite critical in ASIL simulation. A new that can consider drivers different driving skills proposed this paper. It simulate overall performance vehicles by adjusting parameters, with which impact a certain and are evaluated. This paper taken regenerative braking object double-lane-change scenario to typical...
In this paper we consider the problem of modeling and control a computer controlled brake system. The model is developed using series experiments conducted on test bench which contains full scale subsystem Lincoln town car actuator designed by Ford Motor Company. has form first order nonlinear system with nonlinearities lumped in coefficients. controller design makes use standard feedback linearization technique along intuitive modifications to meet closed loop performance specifications....
