improvement in braking performance and vehicle stability can be achieved through the use of braking systems whose brake force distribution is variable. electronic braking force distribution has an important and serious role in the vehicle stopping distance and stability. in this paper a new approach will be presented to achieve the braking force distribution strategy for articulated vehicles. f...

This paper presents a power control structure for a brushless permanent magnet electric machine, where both generating and motoring operation modes using the same power stage coexist using a digital control scheme. In the generating mode, desired dynamic output such as constant power and constant torque can be achieved for use in an exercise bicycle, where the input power generated by pedaling ...

Costs for traction energy in DC electric rail transit systems depend on the energy actually demanded in the substations as well as on average power peaks there. Both are strongly influenced by the applied train timetable, because synchronous powering of multiple trains causes high power peaks whereas coordinated powering and braking of trains leads to good usage of regenerative energy from brak...

Abstract: With its large capacity, the total urban rail transit energy consumption is very high; thus, energy saving operations are quite meaningful. The effective use of regenerative braking energy is the mainstream method for improving the efficiency of energy saving. This paper examines the optimization of train dwell time and builds a multiple train operation model for energy conservation o...

In order to improve the downhill regenerative braking control effect of hybrid electric vehicle (HEV), this paper designs a method for (HEV). Firstly, structures system, auxiliary system and eddy current retarder (ECR) are analyzed. Secondly, torque ECR when HEV is calculated. Then, process dynamically analyzed, force distribution constraint realized according relevant laws regulations. Finally...
