Vehicle needs suspension and steering systems with different features to fit different driving conditions. In normal straight driving condition, soft suspension and heavy steering systems are needed to achieve better ride comfort and straight line driving stability; in turning conditions, hard suspension and lightweight steering systems are needed to get better handing stability. The semi-active suspension system with Magneto-Rheological dampers can improve the ride comfort and handling performance of vehicle. Electrical power steering system is developed rapidly due to its portable and flexible operations as well as stable steering performance. In this paper, the features of electrical power steering and semi-active suspension systems have been done a more in-depth study, and an integrated control strategy was proposed to achieve the coordinated control of these two electric control systems arises in order to improve the ride comfort and ensure the steering stability in cornering situation. In a well on the basis of experimental data, the mathematical model of electrical power steering and semi-active suspension systems were adopted to predict the characteristics of these two electric systems. The numerical simulation results show that the integrated control strategy is effective and successful in improving the overall performances such as rapid electrical power steering and good body post regulation. The primary goal of this paper is to create an effective, reliable and safe integrated control strategy for steering and suspension systems that improves the ride comfort as well as handing stability. © 2012 SAE International.

The steering torque variation which is an important evaluation index of the vehicle handling stability directly influences the feeling of driving. The objective of this chapter is to optimize the hard points and the phase angle of steering column assembly in order to reduce the torque variation to the minimum, and improve the vehicle handling stability. In this chapter, the formulas for accurate calculation of the angular velocity ratio and the torque variation in double cross universal joints system are deduced according to the transmission analysis of single cross universal joint. Based on the study of the formula for approximate calculation of the rotational angle deviation in double cross universal joints system and the calculation of the torque variation using MATLAB software, an effective optimization method of the phase angle which could be applied to reduce the angular velocity ratio and the torque variation is obtained. The torque variation could be calculated exactly and reduced to the minimum by using the optimization method and formulas in the early stage of steering column assembly layout. The formulas and optimization method could also be applied to other cross universal joints transmission system. © 2013 Springer-Verlag. Source

The chapter discussed the method of power distribution of passenger vehicle, and indicated the key points of power distribution. Via analyzing the property of electronic and electrical parts in vehicle, we ascertain the load characteristics of electronic and electrical parts, define the load types of different electronic and electrical parts, define the application strategy of fuses and the original power distribution draft. According to the numbers and power of load, calculate the capability of fuse and choose the type of fuse. Then, via the capability of fuse, calculate the diameter of wire connecting with the fuse. Finally, summarize all the information to design the particular power distribution drawing. The process method and key points of power distribution discussed in the chapter are based on an economical car of FAW R&D Center, and the design result is validated by the economical car. The chapter mainly discussed common fuse and wire diameter selection, did not contain some special fuse such as main fuse selection principle or contain the layout and number of fuse. Nowadays, there're few articles about the power distribution study. However, this chapter discussed the power distribution systematically in order to assist the design of power distribution and guide the engineering design of power distribution of passenger vehicle. Power distribution is the key point of electrical system design. The chapter discussed the process, method and key points of power distribution. It is verified by an Economic car. This chapter discussed the power distribution in order to assist the design of power distribution and be helpful of the engineering design of power distribution about passenger vehicle. © 2013 Springer-Verlag.

With the development of the car industry and the rising of consumer's requirements for comfort, brake noise gradually becomes one of the important factors to appraise the comfort of vehicle. This paper, aiming at solving the noise problem of the passenger car, researches the mechanism of brake noise's generation and the ways to optimize it in order to reduce the noise. The brake noise is tested according to the road test standard. The frequency and intensity of the noise are recorded in the vehicle test. At the same time, the relation of speed and the noise's frequency is recorded. The brake noise is divided into Squeal noise and Groan noise based on the test results of the car. Squeal noise: It is important to collect more information in the dynamometer which used suspension assembly to analyze the character of noise. The noise mechanism is analyzed and the optimum direction is found through the computer CAE technique. Groan noise: Based on the calculation and analysis of the test results, the main influencing factors of the noise are found and the optimum scheme is designed. Finally the performance of brake noise is validated in the dynamometer and the vehicle test. Computer analysis and test results show that Squeal noise is caused by the resonance of the brake system. In this paper, brake noise is reduced by reducing the stiffness of the brake disc by an average of 5%, optimizing the inherent character of the brake system and improving the stability of the brake system. Based on the test and the analysis, the main cause of the Groan noise is that the structure of brake pad and brake disc's ventilation is designed with defects. Groan noise is related to the structure of brake pad and brake disc's ventilation. It is effective to reduce noise by optimizing brake pad's structure. © Springer-Verlag 2013. Source

To predict vertical step passability of wheeled vehicle and get driveline torque, this paper presented a unified obstacle crossing model. The model could simulate climbing process of any given axle of a vehicle with any axles. Factors such as adhesion coefficient difference between climbing wheel and rolling wheel, suspension bound and rebound limits, wheel liftoff were considered. Passability criteria of simulation results was discussed. The model was validated through tests. Influence of suspension bound limits on driveline torque was analyzed. ©, 2015, China Mechanical Engineering Magazine Office. All right reserved. Source
