in this paper, an adaptive rule based controller for an anti-lock regenerative braking system (arbs) of a series hybrid electric bus (sheb) has been proposed. the proposed controller integrates the regenerative braking and wheel anti-lock functions by controlling the electric motor of the hybrid vehicle, without using any conventional mechanical anti-lock braking system. the performance of the ...

Nonlinear hunting speeds of railway vehicles running on a tangent track are analytically obtained using Hopf bifurcation theory in this paper. The railway vehicle model consists of nonlinear primary yaw dampers, nonlinear flange contact stiffness as well as the clearance between the wheel flange and rail tread. Linear and nonlinear critical speeds are obtained using Bogoliubov method. A compreh...

The article analyzes the motion of a wheelset along path unequal length with shaft wear rails. authors have studied influence an external disturbing force on parametric system “wheel-rail”. considered problem is solved basis mathematical model interaction pair wheels and rail, taking into account additive effect stiffness rail vehicle. It shown that elasticity track in longitudinal direction al...

A major research gap is the relative ridership performance of Bus Rapid Transit (BRT), Light Rail Transit (LRT), and streetcar (SC). This paper assesses ridership influences of 101 routes in Australia, Europe, and North America using multiple regression examining the influence of transit mode, vehicle capacity, service level, employment/residential density, car ownership, speed, stop spacing, r...

Detecting unexpected obstacles and avoiding collisions is an important task for any autonomous mobile system. This article describes GANESHA (Grid based Approach for Navigation by Evidence Storage and Histogram Analysis), a system using sonar that we implemented for the autonomous land vehicle Navlab. The general hardware configuration of the system is shown, followed by a description of how th...
