-This paper presents the control of a Permanent Magnet Electric Variable Transmission (PM-EVT) for Hybrid Electric Vehicles (HEVs). Consisting of two electric machines, the EVT realizes the power split function in an electromagnetic way rather than in a mechanical way. A specific PM-EVT has been designed for Toyota Prius II. The control scheme of the entire vehicle is deduced using the Energetic Macroscopic Representation methodology. The energy management strategy yields local control references. A specific attention is paid for the field weakening for wide speed range. Simulation results are provided to illustrate the EVT modeling and control.

“…1 Vinot et al 2 use optimal offline management with discrete dynamic programming to evaluate the fuel consumption in the global design process of an EVT, aiming at minimizing fuel consumption and the number of battery cells. Kessels et al 3 face the optimization of the power flow by means of an integrated powertrain control considering the efficiency of all powertrain components, aiming at energy efficiency. Similarly, other authors focus on different transmission layouts, for example, series 4 or parallel 5 hybrid architectures, always limiting to fuel economy or low emission aspects; Delkhosh et al 6 present a control strategy that can be used only for hybrid vehicles with Continuously Variable Transmission (CVT), proposing an optimization for different driving cycles.…”

This article deals with the dynamic behavior of a passenger car equipped with an electrically variable transmission, which is analyzed both in time and frequency domains. After deriving the dynamic equations in the state-space form for both open-and closed-loop systems, a methodology for objectively evaluating the drivability of this over-actuated system is proposed. Several simulation results are presented with the aim of highlighting the transient response to fast engine torque changes and the effect of the generator speed controller calibration on the system dynamics. Moreover, the influence of the ratio between electrical and thermal power on the frequency response is discussed. The proposed analysis, which is based on a simple static torque split between internal combustion engine and propulsion electric motor, depicts the dynamic signature of the electrically variable transmission powertrain system, without any additional drivability filter. Hence, these results can constitute the base for the design of dynamic torque splitting aimed at optimizing the longitudinal vehicle response to the driver's acceleration demand.

“…The application of convex optimization to the design and operation of electrified powertrains is not new. The potential of using convex optimization in this context was pointed out already in the late 90s in [14], and more recently [15], [16], [17], [18], [19]. In these studies, convex optimization was used to compute the optimal energy management, either over an entire driving cycle or, as an ingredient of a predictive control scheme, over a limited time horizon.…”

The electrification of road transport is accelerating globally, propelled by a mix of environmental concerns, legislative mandates, and business opportunities. Relying to a larger extent on electricity in the transportation sector provides new opportunities to reduce CO 2 emissions, fossil fuel consumption, and local air pollution by improving energy efficiency and employing renewable energy. As part of this development, leading vehicle manufacturers are currently making a substantial effort to provide Hybrid Electric Vehicles (HEVs), Plug-in Hybrid Electric Vehicles (PHEVs), and pure Electric Vehicles (EVs) to the market. This potentially major change in the transportation system entails significant challenges, [1], [2]. The technology in several vital areas, such as components for electric energy storage and electric drives, needs to be developed further. Effective control design tools are also needed to master the increased complexity of the new powertrains. This increased complexity concerns both design and operation of vehicles, and the interplay between vehicles and the infrastructure, such as the electric grid and systems for navigation and traffic information. There are several interesting control design issues related to vehicle electrification. In this article, we will focus on some of these issues for two common powertrain configurations, known as series and parallel, respectively; see "Hybrid Electric Powertrains" for an introductory description. The two configurations share a common characteristic, namely the additional degree of freedom compared to a conventional powertrain. In response to the driver's power demand, as expressed by the accelerator command, there is a need for the control system to arbitrate
