System identification is the basis of designing control system, and it is very difficulty to identify the nonlinear system today. A method of fuzzy identification had been provided in reference 1, and another method of using neural networks to identify system had been provided in reference 2. In this paper, Author points out the disadvantages of those(More)
In the light of the conditions that the results of traditional criticality safety vehicle distance are hardly able to guarantee the safety in the sudden reaction of the current vehicle, through studying the conditions of traditional criticality safety distance, considering the impact of abnormal deceleration of the current vehicle on following vehicle, and(More)

In this paper a novel approach for nonlinear system identification is proposed based on adaptive particle swarm optimization. Particle swarm optimization is demonstrated as efficient global search method for complex surfaces, and in order to quick the convergence speed, an adaptive particle swarm optimization strategy was introduced. The proposed method(More)
The improved P-2D HMM is introduced to the driving intentions identification, and the driving intentions identification model based on continuous P-2D HMM was estabLished to identify the driving intention. The vehicle space, speed and lateral acceleration were as inputs, the driving intentions as output. Predict the driving behavior at next period to(More)
A support vector machines (SVM) approach is proposed for grout stratum identification based on the grout instrument measurement datum in the grouting consolidation project. The important features of SVM model are obtained by analysis of grout fluid penetration mechanism integrating with grout physical model for pressure control aim. Then we introduce(More)
Air fuel ratio is a key index affecting power performance and fuel economy and exhaust emissions of the gasoline engine, whose accurate model is the foundation of accuracy air fuel ratio control. Taking HL495 engine as experimental device, a method of indenting air fuel ratio based on Elman neural network was provided in this paper. Experiment results show(More)
Through researching at the traditional linear model of car-following, the paper have found it sensitivity is a fixed value, but in the actual process of driving a vehicle, Sensitivity of driver changes with stimulation. This paper set up a new vehicle-following model taking into account the different sensitivity. Through simulation analysis, results show(More)
