This article establishes the mathematical model of automobile anti-lock braking system (ABS) in the Simulink environment and tracks the research and simulation of the ABS established mathematical model, which is based on the control module with the PID controller. From the simulation curve, we can verify automobile ABS with good braking performance and direction maneuverability. © 2012 World Scientific Publishing Company. Source

The determination principle of the transmission and the gear number in the electric vehicle driving system are studied in this paper. The results show that the rated power or torque and speed of the motor must reasonably match the parameters of transmission system. A type of electric vehicle is taken as the research object. Two of the five manual transmission speeds gears are calculated and analyzed, which are the equilibrium diagram of the driving force and the driving resistance force between the second gear and the third gear. The single gear-driven scheme of the fixed speed ratio reducer is proposed to replace the heavy mechanical gear reducer. It can reduce the mass of the whole vehicle and increase the driving distance from the theorem. Appling the simulation software Advanced Vehicle Simulator (ADVISOR) of electric vehicle to simulate the vehicle power performance and continued mileage, it verifies that the parameters determination principle and the method of the proposed drive system are correct. © 2012 World Scientific Publishing Company.

Based on Landsat ETM+ remote sensing data and historical geography analysis, this paper studied structural characteristics and driving factors for polder (artificial dike-surrounded field) landscapes in the East Chaohu Area of Anhui Province, China. According to the characteristics of polder structure and spectral analysis of typical objects, differential methods were used to gain structural characteristics of polder landscape in this area. The results indicated that the spatial structural characteristics of polder landscape could be divided into six categories: polygon-shaped structure, jaggies-shaped structure, dendritic-shaped structure, feather-shaped structure, cricoid fan-shaped structure, and rectangular-shaped structure. All six landscape structures were formed by the long-term human exploitation of farmland, reflecting different natural and social functions of polder's construction. Finally, combined with regional environment and historical literature, this paper synthetically analyzed the five main driving factors of this artificial field development. © 2013 IEEE. Source

To resolve the problems of small module gear measurement with traditional methods, a new method for measuring the tooth profile deviations of small module gear using the optical image measuring instrument is put forward. According to the ISO 1328-1, the mathematical models of total profile deviation, profile form deviation and profile slope deviation are proposed. The involute profile measurement schemes are given. The results show that tooth profile coordinate values of small module gear can be measured automatically and effectively with the optical image measuring instrument, and the provided method has higher precision of getting measuring points and less fitting error of tooth profile. © (2013) Trans Tech Publications, Switzerland.

The present rear-end collision accident proportion on the road increases day after day, car collision avoidance system is more and more paid attention. Analysising the existing car collision avoidance system, we propose a car anti-collision algorithm based on safe distance model in this paper. This method takes the influence factors of safety distance for main parameters which fully considers the speed change and the acceleration change of the car 1 and the car 2. It may realize real-time information acquisition and warning judgment according to the state of car 2, the car could automatic braking if necessary. VB simulation shows that the algorithm can effectively avoid collision, also automatically maintain the distance between vehicles, and lay a foundation for further research on the unmanned car. © (2011) Trans Tech Publications.
