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...
For the bus has serious impact on the intersection running effective, the paper gives a new passenger car equivalent method for the bus according to the bus's time-space characteristics. When the bus arrives and departs the intersection without stopping, the passenger car equivalent is set as the section of highway, when the bus passes the intersection experiencing stop, the passenger car equivalent...
Based on ultrasonic principle, the car rain protection airproof performance test method was proposed after the main problems of the current artificial rain test were put forward. In the new method, the detection and evaluation was separated which means that the real-time detection, in the use of ultrasonic, could be achieved as the car enter the venue and according to the on-site analysis of the collected...
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...
It is a crucial part for ATMS to accurately identify and forecast traffic state from real-time traffic data. To improve the identification rate of traffic state, multisource information should be used. The multisource information fusion method is important. Information fusion is divided into three levels, i.e. data level, feature level, and decision level. In traffic congestion identification, many...
