Direct yaw moment control (DYC) is the most potential chassis control method applied to electric vehicles (EV). In this paper, three stability controllers aimed at different targets based on sliding mode control (SMC) are designed: Yaw rate controller improves the vehicle stability by controlling the yaw rate; Slip angle controller is aimed at maintaining a minimum side slip angle; United controller...
Genetic algorithm is one important method for solving vehicle routing problem. Genetic algorithm has the special advantages in solving vehicle routing problem. A genetic algorithm for logistics vehicle routing problem is designed and implemented in this paper. At the same time the key technologies such as the implementing of the genetic algorithm based on natural number encode in the logistics vehicles...
Within this paper, the modality of vehicle frame is analyzed by finite element software of ALGOR, and carrying out the first 10 steps natural frequency resonance and vibration model. Using mode of two-degree-of-freedom vehicle vibration builds system's movement differential equation and simulates the frame's vibration by Simulink module of Matlab. Then make a dynamic response simulation for vehicle...
In this paper, the ANSYS is used to establish a three-dimensional model of brake drums, and then simulate the process of the brake drums' temperature rising through the forcing of boundary loads and initial conditions. After that the author reveal temperature field distribution of the brake drum brake element model, then verify the accuracy of model by an experiment, which lay a theoretical foundation...
With the assumption that NSV suffers the violent changes of aerodynamic paameters and the outside disturbance in hypersonic condition, to achieve high precision, an (fuzzy disturbance observer)FDO is designed which improves the approximation ability of the observer on-line. The strict proof of the Lyapunov stability is provided simutanously.
Detecting vehicles from video sequence is very challenging due to the wide varieties of vehicle appearances and the complexity of the backgrounds. At present, many algorithms in the image recognition have a narrow applicability and a weak real-time. Aiming at this problem, a recognition method which was combined by features extraction using Gabor wavelet and BP neural network algorithm for the classification...
