Hybrid electric tracked bulldozers use engine and ultracapacitor as the power sources for propulsion, and the fuel economy performance highly depend on the coordination of all subsystems. In this paper, a model predictive controller is developed to reduce the fuel consumption of hybrid electric tracked bulldozers. As an optimization-based approach, the model predictive controller usually requires...
This paper presents an anti-idling regenerative auxiliary power system for service vehicles. The energy storage system in the regenerative auxiliary power system is able to electrify the auxiliary systems so as to achieve anti-idling. Service vehicles (e.g. delivery trucks or public buses) generally have predetermined routes, thus it is feasible and profitable to utilize a model predictive control...
This paper presents a novel anti-idling system, namely, a regenerative auxiliary power system (RAPS) for service vehicles. Auxiliary devices, such as a refrigeration system in a food delivery truck, require the engine to idle for providing auxiliary power while the truck stops for loading or unloading. By electrifying auxiliary systems, a battery pack can supply the auxiliary load, thereby reducing...
