A yaw moment control based on fuzzy logic is proposed to deal with high nonlinearity in vehicle dynamic systems. The developed controller generates the suitable additional yaw moment which is obtained from the differential longitudinal braking forces in driving wheels so that the vehicle follows the target values of the yaw rate and the sideslip angle. A(More)
BACKGROUND Traumatic cervical spinal cord injury with subaxial fracture and dislocation not only indicates a highly unstable spine but can also induce life-threatening complications. This makes first aid critically important before any definitive operative procedure is undertaken. The present study analyzes the various first aid measures and operative(More)
Antilock braking system (ABS) is an important part to improve the automobile's active safety. In general, ABS is designed to achieve maximum negative acceleration by preventing the wheels from locking. Researches show that the friction between road and tire is a nonlinear function of wheel slip. In this paper, to deal with the strong nonlinearity in the(More)
This paper examines the feasibility of proposed control for independent four-wheel drive electric vehicle. According to vehicle longitudinal velocity and the tire-road condition, a new method to determine the target value, i.e., vehicle yaw rate and side slip angle, is presented. The effectiveness of the designed controller based on sliding mode control is(More)
In this paper, a quarter dynamic model of a two wheel drive electric vehicle is established and an acceleration slip regulation (ASR) algorithm based on fuzzy PID control is realized. The fuzzy PID control system for wheel slip regulation at its optimum value is designed and simulation has been carried with Matlab/Simulink. The simulation results show that(More)
The anti-lock braking system (ABS) can improve the safety of the vehicle. As the ABS assisted device, electronic brake force distribution (EBD) can automatically regulate the braking force distribution among the wheels of the vehicle, so that the wheels can reach the start condition of ABS at the same time, which can make better performance on braking(More)
A direct yaw moment control (DYC) method based on optimal and predictive control is proposed in this paper. The 8-degree-of-freedom model of electric vehicle and the non-linear Unitire model have been developed. The simulation results verified the validity of control strategy. The control method of electric vehicle put forward in this paper can reduce the(More)
In the actual satellite positioning and navigation system, multi-path effects not only cause distortion of the pseudo-random codes and navigation messages, but also cause the carrier phase distortion. For the problem of acquisition of BOC signals spreading in the multipath fading channel, a comparison between acquisition performances of different channels(More)
Multiple sequence magnetic resonance imaging (MRI) is often hampered by noise and misalignment. The wavelet de-noising lacks directivity and does not preserve image details, which limits its effectiveness. To solve the problem, an adaptive threshold de-noising method based on wavelet transformation is employed. As to misalignment, a registration method(More)
Computer technology has radically changed the work of dictionary compilation and brought about a revolution in the writing of dictionaries. Computer-based corpora have an important effect on work of modern lexicography. The article has discussed the shortcomings and disadvantage of pre-electronic corpora in lexicography. It has exposited the effect of(More)
