Abstract: Combined with the wavelet analysis, the fuzzy theory and the BP neural network this paper constructs the fault diagnostic method of the wavelet fuzzy BP network. In the process of the automotive fault diagnosis, through comparing the common BP neural network with the wavelet fuzzy BP network, the result indicates that the wavelet fuzzy BP network has the characteristics of higher precision and faster convergence speed etc.

Abstract: According to the super large or heavy vehicle accidents existing wrecker cannot complete the wrecker rescue mission independent problems, puts forward the design of a practical game type crane wrecker. The hoisting mechanism as the research object, the traditional mechanical method is designed and calculated, then the three-dimensional entity model using 3D mechanical design software Solidworks, and imported into the finite element analysis software ANSYS to analyze the static mechanics characteristics of the structure, to improve the local strength of short position. On this basis, a lifting test vehicle prototype, rated load operation and overload operation condition test, and measure its subsidence. With the analysis of the experiment results, show that the design truck lifting organ can meet the demand of the technology.

Abstract: An electric window control system based on low-speed CAN bus has been developed to reduce the wiring harness of vehicle control system, improve the system reliability and cut overall costs. On the basis of requirement analysis of the control system, a CAN application layer communication protocol has been defined. The electric window control system has been designed using Freescale 16-bit single chip microprocessor MCS12DP256 as central processing unit, and the control software has also been developed, in which an integral algorithm was used to realize the anti-pinch function.

Abstract: This paper put forward an automobile intelligent electronic control automatic clutch systems, use the electromagnet controlled by circuit to replace the clutch pedal of manual car. Through the switch, we can automatically control the detachment and combination of the initiative part and the driven part of clutch, which makes the operation of automatic car more convenience.

Abstract: Along with the popularization of artificial intelligence and information technology, the development of automobile industry have been closely combined with information technology, environmental protection and energy saving ideas, promotion and application of electronic control technology, which development cycle becoming shorter and shorter. In this paper, through the analysis of the present application situation and development trend of the automobile electronic technology at present, in order to provide a theoretical reference for the future development of the automobile electronic control technology.

Abstract: Most Automotbile Electric Power Steering (EPS) controller designs are based on a simplified accurate model,however,EPS controller is affected by many nonlinear friction and damping easily, such as road condition,sensor noises and the lateral wind disturbance.These uncertainties affect the accuracy of assist current, the EPS performance and the driving safety. Aimed at the nonlinear MIMO system of electric power steering system,the mechanism and dynamic characteristic of EPS is analysed,and EPS model is developed. Then the fuzzy-neural network controller is designed and the corresponding simulation is performed.The results show that the proposed EPS control strategy can provide good performance of stability and controllability and can increase the anti-jamming capability of vehicle.

Abstract: The role of bill of material (BOM) was firstly introduced. Then, the techniques of how to establish modular BOM in multi-products enterprise was analyzed to realize accuracy and just-in time delivery of materials.

Abstract: I propose to design and test a steer-by-wire system will demonstrate that the physical connection between the steering wheel and the wheels of a car which can be eliminated in favor of a more robust system that allows for easy modifications. The system will mimic regular power steering and the driver will feel no difficulty in adjusting to the new system and yet will benefit from the many advantages of the system. Today’s automobiles benefit more and more from the vast applications of electronic systems. The integration of a steer-by-wire system can enhance these systems notably to a wide range. In particular, the handling and the safety of the cars can be improved significantly. Since a steer-by-wire system is easily modifiable, different drivers will be able to adjust the system to accommodate their styles and this will enhance easy handling. In addition, disabled people and the elderly will benefit immensely from steer-by-wire because they will be able to situate the steering wheel to meet special needs. Traction control systems are very closely tied with driving safety and they can be enhanced with steer-by-wire vastly [3]. For instance, if the car starts sliding and the driver loses control of the car, driven off the steering into the wrong side, the system could interfere and take over controls. Very sudden changes in steering could also be avoided with such a system. Since there are virtually no physical connections between the steering wheel and the wheels, a steer-by-wire system can be implemented on different cars easily. The steering wheel could be placed on either side of a car (or anywhere else). Both of these improvements would reduce costs of production and allow a wider range of designs eminently.
