This paper aims at proposing an improved generalized dynamic rollover threshold of multi-axial vehicles based on lateral load transfer ratio (LTR) and providing the foundation for rollover prediction. The study is carried out by utilizing vehicle handling dynamics to build a vehicle rollover model, which takes into account the characteristics of suspension and limit equilibrium of tires' lifting-off...
Probes coupling signal is usually ignored in traditional near-field imaging simulation, which has effect on the imaging result. This paper corrects the problem by adding coupling items in scattering equation and modifying the distance between transceiver and target. Image changing with the coupling signal and the coupling distance is investigated. Background subtraction technique is used in the simulations...
In this paper, the features of electrical power steering and semi-active suspension systems have been done a more in-depth study. In order to achieve the common objective of improving the ride comfort and handing stability of automobile, an integrated control strategy was proposed to achieve the control of electrical power steering and semi-active suspension systems. In a well on the basis of experimental...
The engine brake characters and its influence factors are introduced, and the experiment of engine brake performance is expounded. The necessity of control continuously variable transmission (CVT) ratio during engine braking is discussed. When engine braking, the engine brake torque based on object velocity is estimated. With the characteristics curve of the engine brake torque and engine speed-brake...
TCP-friendly congestion control is the key technique in next-generation-networks. An effective congestion control which uses the predominance of dynamic thresholds self- adaptive TCP-friendly congestion control (DATFCC) is proposed. The size of the receiver buffer butter was dynamically adjusted according to the state of the networks, the dropping probability was determined by the type and the size...
Environmental pollution, traffic accident and so on, all these externality problems caused by transportation conflicted with the accepted social sustainable development. Many countries adopted the pollution control, transportation regulation or other restrictive policy to solve the problems, but on the whole had little effect. To show new thoughts to this problem, the paper studies the measures by...
After introducing the features and requirements in an industrial control networks, the properties of several wireless media access control protocols such as MACA, MACAW, IEEE802.il and WTRP are analyzed. An innovative MAC protocol based on token control is proposed to suit the requirements of WICN (Wireless Industrial Control Network). Logical ring under wireless link is defined; mechanisms of token...
