Compared with traditional guard management, this system uses radio frequency identification technology (RFID) to achieve intelligent access management. When need identification, RFID reader issues a fixed frequency radio. Then label card is stimulated, and returns ID number. By ID number and database information, we have developed a lot of access control management functions, such as staff automatic...
The rapid development of auto shift technology helps improve the control strategy determination of automatic transmission in construction vehicle. The overall shift schedule is defined as the time of shift gear with the change of controlling parameters. The rule should be a unit value. Even if there are many input variables, it has the only one output state. Based on the different designed constructions...
At present the method of detecting traffic affairs through video sequences is epidemic at home and abroad in intelligent transport systems, though improving the accuracy and reducing false alarm rate are the focuses of today's research. This paper proposes an incident detection method based on the steady-state differences of adjacent videos. The method first acquires data on basic features of the...
The finite element model for a commercial vehicle cab body in white is set up. The static stiffness and numerical modal of cab are analyzed. Considering the influence of welding spot on static stiffness, strength and first order modal frequency, the welding spot of cab is divided into two areas based on element strain energy density. And welding spot layout of the two areas are optimized by topology...
In view of the deficiency of the endurance mileage of pure electric vehicle, parameter design and related analysis of powertrain for extended-range electric vehicle including power drive system, energy storage system and range extender were conducted. Based on Matlab/Simulink, model of extended-range electric vehicle was built and simulation was carried out in the NEDC driving cycle. The simulation...
This paper is concerned with how to accurately position and find an optimal path through Vehicle Navigation System. This article designed a vehicle dynamic navigation system based on Internet of Things, by using the improved Ant Colony Algorithm. Through computer simulation, we obtained two simulation figures of static navigation route and dynamic navigation route. Besides, the driving directions...
Based on the analysis of the domestic and foreign research on alcohol ignition interlock devices, this paper puts forward an intelligence prevention system of drink-driving according to alcohol concentration in the drinking driver's breath that can detect the driver whether does he drink when the vehicle stars or runs by using sensor technology, computer technology, control technology, communication...
In order to improve fuel economy and reduce exhaust gas emissions, hybrid and electric vehicles use the electric motor as a generator for regenerative brake during deceleration, which converts kinetic energy of the vehicle into electrical energy. To maximize the recovery of braking energy, special brake system is needed to blend control the regenerative brake force and hydraulic brake force. This...
An important characteristic of electrical vehicle is that there is high voltage of power cycle. The passive safety is very important in electrical vehicle's crash, compared with normal vehicle. First, the crash standard of electrical vehicle is analyzed. Then the crash test's process is researched. With the dummy's injury data of head and thorax and vehicle's acceleration, which come from different...
Different side impact dummy is used depending on different regulations. There are two typical side impact dummies in the world. One is SID dummy used in US side impact test, and the other is Euro SID dummy. Euro SID dummy has two generations, and they are EuroSID-1 and ES-2. There is also another new dummy called ES-2re. This paper try to research ES-2re Rib Extension, and discuss the effect of Rib...
The frame three-dimensional entity model of a formula racing car is established on CATIA software platform, and is analyzed by finite element through the ANSYS software. Through the analysis of the static typical working conditions of the frame (bending and torsion conditions of the frame), find the affluent parts of the strength and stiffness of the frame, reduce the number of pipe fittings and diminish...
This article proposes an improved watershed algorithm based on morphological, using morphological open and close reconstruction to reduce the noise of image. Besides, with the Weber Perception Principle, it divides the morphological gradient image in the form of gray scale and non-linear and marked the gradient image with Watershed Algorithm. So it solved the over-segmentation problem of traditional...
