Driving Stability of Closed Loop Tractor-semitrailer Vehicle System with Optimal Driver Model

摘要：

A quasi-linear driver model was developed, and a closed loop tractor-semitrailer vehicle system composed of the driver model and a tractor-semitrailer vehicle model of 3degrees-of-freedom were proposed. The stability of closed loop vehicle system was studied by simulating the system with different parameter values. A roots-locating numerical method was used to identify critical speed of the system. Some simulation of closed loop vehicle system were made in Matlab and the results shown that drivers inherent time delay, a semitrailers load and driving speed make important role in stability of closed loop tractor-semi trailer.
