With the increasing numbers and importance of Electronic Control Units (ECUs) in modern automobiles, there is a need to monitor system and signal integrity to enable desired system behavior. Among the various signals in a vehicle, those associated with torque commands must be prioritized over others while preserving signal integrity as they have a large impact on meeting the powertrain performa...

The goal of this investigation is to propose a series/parallel hybrid electric power system for ultralight aviation designed improve safety and, possibly, reduce fuel consumption. consists Wankel engine, two machines, battery, and planetary gear set, all acquired from the automotive market. After preliminary design based on takeoff power, simulated over typical flight mission in case engine fai...

Among the auxiliary loads in light-duty vehicles, air conditioning system is single largest energy consumer. For electrified impact of heating and cooling becomes even more significant, as they compete with powertrain for battery use can significantly reduce range or performance. While considerable work has been made field optimal management vehicles optimization vehicle velocity eco-driving, f...

This work concerns the study and the modeling of hybrid Proton Exchange Membrane (PEM) Fuel Cell electric vehicle. In fact, the paper deals with the model description of the powertrain which includes two energy sources: a PEM Fuel Cell as a primary source and a supercapacitor as a secondary source. The architecture is two degrees of freedom permitting a stability of the DC bus voltage. The hybr...

The high efficiency of the flywheel hybrid powertrain, as well its power characteristics, can help to meet energy/power conversion needs, which may prove be promising. Moreover, powertrain reduce dependence on batteries. This paper presents EC-BERS in order capture more mechanical than rated power, and charge/discharge cycles battery. In this new energy recovery system, maximum torque obtained ...

Fuel cell-battery hybrid systems for the powertrain, which have advantage of emission-free power generation and adapt to material transport emission reduction, are investigated. Based on characteristics fuel cell system electric forklift truck powertrain system, this work defines design principle control strategy improve overall performance economy. A simulation platform vehicles has been estab...

We present the verification of a benchmark powertrain control system using the hybrid system verification tool C2E2. This model comes from a suite of benchmarks that were posed as a challenge problem for the hybrid systems community, and to our knowledge, we are reporting its first verification. For this work, we implemented the algorithm reported in [9] in C2E2, to automatically compute local ...
