In recent years, eco-driving for hybrid electric vehicles (HEVs) has been studied with the emerging connected and automated vehicle (CAV) technologies to improve mobility, fuel economy safety of HEVs. This paper develops a hierarchical control strategy HEV platoons consisting CAVs human-driven (HDVs) at signalized intersections. For each platoon, speed trajectories are optimized in upper layer ...

Along with the common goal of reducing fuel consumption for vehicles, the hybrid electric vehicle stands out as a mean for more fuel efficient driving. Besides the conventional combustion engine and fuel tank, the hybrid electric vehicle is also equipped with an electric motor and a battery for propulsion. Car manufacturers are presently working to provide the markets with the next step of this...

In order to realize optimal power distribution between proton exchange membrane fuel cell and supercapacitor in hybrid electric tram, an online extremum seeking-based optimized energy management strategy is proposed this work. Considering that the a complex nonlinear system, its performance will vary as external parameters change, so it necessary consider state of stack. An seeking algorithm in...

Abstract In order to improve the economy of hybrid electric-electric ship, parallel electric ship is taken as research object, and an energy control strategy based on minimum equivalent fuel consumption proposed. The efficiency factor its correction function are used maintain balance battery power, target optimization adjusted power rate battery, thereby realizing for traveling ship. Finally, M...

Abstract Greenhouse gases jeopardize world’s climate. A significant amount of these pollutants is produced by road vehicles, so their producers are forced to reduce emissions significantly. This means that every car manufacturer expanding electrified vehicle range. Fully electric vehicles the best way for long-term elimination greenhouse production in transport. However, short term it not possi...

Fuel cell hybrid electric vehicles (FCEVs) are mainly electrified by the fuel (FC) system. As a supplementary power source, battery or supercapacitor (SC) is employed (besides FC) to enhance response due slow dynamics of FC. Indeed, performance system depends on required distribution manner among sources, which managed energy management strategy (EMS). This paper considers an FCEV based proton ...

Improvements in hybrid electric vehicle fuel economy with reduced emissions strongly depend on their supervisory control strategy. In order to develop an efficient real-time supervisory control strategy for a series hybrid electric bus, the proposed equivalent fuel consumption optimal control strategy is compared with two popular strategies, thermostat and power follower, using backward simulat...

We assume that an individual invests in a financial market with one riskless and one risky asset, with the latter’s price following a diffusion with stochastic volatility. Given the rate of consumption, we find the optimal investment strategy for the individual who wishes to minimize the probability of going bankrupt. To solve this minimization problem, we use techniques from stochastic optimal...

load management and cost optimization are among the important factors in trigenerationsystems and combined cooling, heating and power (cchp) systems. in this study, an innovative cchpsystem uses a gas turbine as the prime mover and has a heat recovery steam generator (hrsg) in addition toan auxiliary boiler, electric and absorption chillers. the system is tied with the bulk electric grid; to ex...

The present work is concerned with the development of a new algorithm for determination of the equilibrium composition of gaseous detonations. The elements balance equations, and the second law of thermodynamics (i.e., the minimization of the Gibbs free energy of products), are used to determine the equilibrium composition of the detonation products. To minimize the Gibbs free energy with tradi...
