—High fuel consumption cost results in drivers’ economic burden. Plug-In Hybrid Electric Vehicles (PHEVs) consume two fuel sources (i.e., gasoline and electricity energy sources) with floating prices. To reduce drivers’ total fuel cost, recommending economical routes to them becomes one of the effective methods. In this paper, we present a novel economical path-planning framework called Eco-Route, which consists of two phases. In the first phase, we build a driving route cost model (DRCM) for each PHEV (and driver) under the energy management strategy, based on driving condition and vehicles’ parameters. In the second phase, with the real-time traffic information collected via the mobile crowdsensing manner, we are able to estimate and compare the driving cost among the shortest and the fastest routes for a given PHEV, and then recommend the driver with the more economical one. We evaluate the two-phase framework using 8 different PHEVs simulated in Matlab/Simulink, and the real-world datasets consisting of the road network, POI and GPS trajectory data generated by 559 taxis in seven days in Beijing, China. Experimental results demonstrate that the proposed model achieves good accuracy, with a mean cost error of less 8% when paths length is longer than 5 km. Moreover, users could save about 9% driving cost on average if driving along suggested routes in our case studies. Copyright © 2018, The Authors. All rights reserved.

The electric vehicle market has witnessed a big growth spurt as a result of the promotion of the transportation electrification in the global. Among electric vehicles, electric passenger cars are the most promising fleet to achieve the global climate target in the next decades, which will lead to a vast potential public charging market. Therefore, evaluating the economy of operating the charging infrastructure from the operator's perspective is especially required. The paper aims at providing an economic evaluation of charging infrastructure in public places in China. In the proposed method, the initial investment cost, the subsidy, the operating revenue and the operating cost are all modeled in detail. Using the proposed model, two scenarios representing the electric vehicle charging in the work place and in the fast charging station are assumed, and the cost and revenue of charging operators are calculated and compared. It is shown that under our assumption the payback period of the charging infrastructure in the work place is much shorter than that of fast charging station. Because the calculated payback period of fast charging station is more than ten years, current fast charging stations are unlikely to profit, and the promotion of the fast charging stations requires further policy support and smart grid technology development. © Published under licence by IOP Publishing Ltd.

For the coach industry, rapid modeling and efficient optimization methods are desirable for structure modeling and optimization based on simplified structures, especially for use early in the concept phase and with capabilities of accurately expressing the mechanical properties of structure and with flexible section forms. However, the present dimension-based methods cannot easily meet these requirements. To achieve these goals, the property-based modeling （PBM） beam modeling method is studied based on the PBM theory and in conjunction with the characteristics of coach structure of taking beam as the main component. For a beam component of concrete length, its mechanical characteristics are primarily affected by the section properties. Four section parameters are adopted to describe the mechanical properties of a beam, including the section area, the principal moments of inertia about the two principal axles, and the torsion constant of the section. Based on the equivalent stiffness strategy, expressions for the above section parameters are derived, and the PBM beam element is implemented in HyperMesh software. A case is realized using this method, in which the structure of a passenger coach is simplified. The model precision is validated by comparing the basic performance of the total structure with that of the original structure, including the bending and torsion stiffness and the first-order bending and torsional modal frequencies. Sensitivity analysis is conducted to choose design variables. The optimal Latin hypercube experiment design is adopted to sample the test points, and polynomial response surfaces are used to fit these points. To improve the bending and torsion stiffness and the first-order torsional frequency and taking the allowable maximum stresses of the braking and left turning conditions as constraints, the multi-objective optimization of the structure is conducted using the NSGA-II genetic algorithm on the ISIGHT platform. The result of the Paret

This paper describes a novel power management control strategy of battery and supercapacitor hybrid energy storage system to improve system efficiency and battery lifetime. In the presented research, the high and low frequency power demand in the load is separated by a Haar wavelet transform algorithm to overcome the problem of battery overload work and associated degeneration in battery lifetime resulting from an ineffective distribution between battery and supercapacitor. The purpose of frequency distribution is that the supercapacitor is used to share high frequency power components of load power demand to smooth the power demand applied to battery. However, the sole frequency control often fails to realize the optimal utilization of supercapacitor because of the uncertain variation in the driving cycle. Therefore, the power demand distributed to supercapacitor is designed to be changeable along with the variation of its voltage, which is another important advantage of the proposed control strategy. The idea is to utilize different decomposition levels of wavelet transform algorithm, which is adjusted by using a fuzzy-logic controller to reduce the adverse influence of both high frequency transition and peak power from the load power demand on battery system. Finally, simulation is conducted to verify the effectiveness of the proposed strategy. © Copyright 2016 SAE International.

In the paper, Adaptive Model Predictive control Strategy(AMPC) for HEB is designed based on battery state of charge(SOC) programming. The reference SOC is calculated based on dynamic programming algorithm(DP). According to the reference SOC(SOCref), control thresholds are adjusted to make the real SOC following the SOCref by parameter adaptive algorithm. The dynamic model of HEB is established by Simulink and AVL Cruise. simulation results are shown that the energy consumption generated by the proposed strategy is significantly lower than that of the Rule-Based(RB) strategy and the economic performance of HEB can be improved.

In recent years, hardware-in-the-loop (HIL) test becomes an effective approach in the design of automotive electronics. One issue of HIL system is that most commercial HIL products are very expensive. With careful analysis of the ECU functionality and reasonable use of the hardware resources, it is possible to realize a HIL system to fully satisfy the test requirements with much lower cost in many cases. In this paper, the possibilities to reduce the cost of current HIL systems are discussed. As a case study, the development of a low cost HIL system for a pure electric vehicle controller is presented, the modeling of the vehicle is introduced and the hardware and software implementations are given. Finally, the feasibility of the proposed HIL system is validated by experimental results.

In this paper, the shift quality evaluation methods of stepped automatic transmission are analyzed first. Then the evaluation criteria of the shift quality are established based on the power-on up-shift of Dual Clutch Transmission (DCT). Finally, the shift quality objective evaluation method of DCT under ideal shift process is proposed. Comparison tests show that the proposed objective evaluation method is in good agreement with the subjective evaluation methods. The model provides a new shift quality evaluation approach for stepped automatic transmission. ©, 2015, Editorial Board of Jilin University. All right reserved.

Vision-based Advanced Driver Assistance Systems has achieved rapid growth in recent years. Since vehicle field testing under various driving scenarios can be costly, tedious, unrepeatable, and often dangerous, simulation has thus become an effective means that reduces or partially replaces the conventional field testing in the early development stage. However, most of the commercial tools are lack of elaborate lens/sensor models for the vehicle mounted cameras. This paper presents the system-based camera modeling method integrated virtual environment for vision-based ADAS design, development and testing. We present how to simulate two types of cameras with virtual 3D models and graphic render: Pinhole camera and Fisheye camera. We also give out an application named Envelope based on pinhole camera model which refers to the coverage of Field-of-Views (FOVs) of one or more cameras projected to a specific plane. Some preliminary simulation results demonstrate the correctness and effectiveness of the system-based camera modeling method. In the future, other camera's effects could be simulated based on this modeling framework. Copyright © 2015 SAE International.
