Development of fuel cell hybrid powertrain research platform based on dynamic testbed 总被引:1,自引:0,他引:1
An experimental research platform based on a dynamic testbed is developed and applied for fuel cell hybrid powertrain integration
and control. A driver brake model is added to the dynamic testbed to simulate the braking process of an electric vehicle.
Sub-systems of the fuel cell hybrid powertrain are tested, and characteristic parameters are obtained. A simulation platform
is constructed in LabVIEW environment, and its validity is verified by dynamic test results. A real time control system is
developed with an embedded PC for the function of rapid control prototyping. Using this platform, fuel cell battery hybrid
and fuel cell supercapacitor hybrid configurations are investigated. This platform provides a powerful tool for fuel cell
powertrain research and development. 相似文献

This research concerns the design of a powertrain system for a plug-in parallel diesel hybrid electric bus equipped with a
continuously variable transmission (CVT) and presents a new design paradigm for the plug-in hybrid electric bus (HEB). The
criteria and method for selecting and sizing powertrain components equipped in the plug-in HEB are presented. The plug-in
HEB is designed to overcome the vulnerable limitations of driving range and performance of a purely electric vehicle (EV),
and it is also designed to improve the fuel economy and exhaust emissions of conventional buses and conventional HEBs. Optimization
of the control strategy for the complicated and interconnected propulsion system in the plug-in parallel HEB is one of the
most significant factors for achieving higher fuel economy and lower exhaust emissions in the hybrid electric vehicle (HEV).
In this research, the proposed control strategy was simulated to prove its validity using the ADVISOR (advanced vehicle simulator)
analysis simulation tool. 相似文献

A controller for a diesel hybrid electric vehicle based on a V-cycle development approach is investigated in this paper. The
hardware and infra program of the Hybrid Control Unit (HCU) are discussed in detail. The hardware system is designed based
on circuit simulation; while the infra system is written with assemble language. Time sharing mode, buffer sharing mode and
multi-task schedule method are used to ensure real-time communication in the infra program design. Based on multi-thread technology,
hardware in loop test system is also designed. The hardware in loop and bench tests show that the controller could meet the
requirements of the hybrid electric vehicle (HEV) and communicate in real-time. Circuit simulation, HCU, infra program and
hardware in loop test form the effective V-cycle development platform to design a hardware system for a diesel HEV controller. 相似文献
