A co-simulation platform for ICC (Integrated Chassis control) system was built under the MATLAB and AMEsim environment. A vehicle dynamic model was developed using the MATLAB software, and a dynamic response model for hydraulic brake system was built using the AMESim software. Then, the data exchanged through the AMEsim special interface module and the MATLAB S-function. The co-simulation platform was modified by hardware in the loop experiment. And the modified co-simulation platform was used under the typical condition for the performance of ICC.

Drive torque coordinated control for four wheel independent-drive electric vehicle with differential drive assisted steering system (DDAS) is presented in this paper. Firstly, the technical detail of DDAS system is reviewed. Then a structure composed of two layers coordinating control loop is proposed. Moreover, the control algorithm of each layer is introduced. At last, the simulations of parking at stand still and double-lane-change maneuvering in several different adhesion conditions are performed. The simulation results show that the coordinating control system can ensure the DDAS system to work correctly and correct the bad influence of DDAS system on vehicle stability.

This paper models and studies the dynamic characteristics of slewing system of 80T truck crane. Analyzing the composition and working principle of the hydraulic system, and building the model of slewing system based on AMESim, then testing the model. And the simulation analysis results indicate the factors which affect the dynamic characteristics of the system and propose the measures to improve them. The results show that adopting the bypass circuit makes the shock pressure reduced 18 percent when the system operates;besides, changing the system's control strategy and installing one-way throttle enhance the stability of braking obviously.
Having examined some shortcomings in existing car-following models, this study put forward to a new optimal velocity function (desired velocity) based on the dynamic equilibrium theory. The paper discusses its formati...

Based on the comparison of control effects of PID control and fuzzy control, this dissertation designed hybrid ratio tracking controller combining the advantages of both PID and fuzzy control. Using MATLAB/Simulink, simulation research of typical working conditions was made, such as start up, acceleration and ramp driving. The results showed that the controller has strong capacity of robust and decoupling and good dynamic response and high accuracy control of steady state, and good dynamic stability under the resistance of outside environment.

By the transmission analysis of the traditional symmetrical bevel gear differential which is acted as the power coupler, we had built the mathematic model, and also built the test-bed, and took simulation test by the NEDC condition. First in the traditional differential coupling test, it appeared power transfer of abnormal and component damage. After analysis the results of the rotational speed, torque and friction power, we retrofitted the test, at this time, it did not appear unusual, and also can reliably transfer power and take differential coupling, and improve the sliding friction work and heat concentrated significantly. This validated the feasibility and effectiveness of differential hybrid system applying in hybrid electric vehicle.
