“…An integrated automatic engine stop/start system shows a 3.4% improvement in fuel economy. A BeltAlternator-Starter (BAS) system [20,21] or Belt-IntegratedStarter-Generator (B-ISG) [22], modified to include an automatic stop/start system and full accessory electrification is the recommended mild hybridization technology for midterm integration. Simulation result of this system integrated into an M1078 indicates a 10.2% improvement in fuel economy when compared to the base model.…”

This paper reports the planning efforts and preliminary results of increasing fuel economy in the current fleet of medium-duty tactical truck. A strategic plan was developed through investigation of current and future technology offerings from original equipment manufacturers and after market suppliers. Research efforts consisted of an initial phase where a broad range of integration candidates were collected and a secondary phase where in-depth analysis was conducted to target those to be considered for inclusion in the strategic plan. The strategic plan lays out the integrated technologies in the near term including auxiliary electrification of engine cooling fan and hydrogen injection. For the mid-term time frame, the plan involves implementing an engine stop/start system and electrifying other auxiliaries. The final step in the plan is the development and implementation of a full hybrid population. The preliminary results include simulation of the electric cooling fan and mild hybrid powertrain, and experimental test of hydrogen injection.

“…When the machine is meant to do just starting and generating or little more, the technical consensus has been to place it on the belt drive, simply replacing the alternator [85,[95][96][97][98][99][100][101][102][103][104][105] (Fig. 21), as opposed to in-line with the engine which is more of a hybrid-vehicle topology.…”

“…Further, the use of PM brushless and induction topologies for hybrid and electric vehicles has generated significant developments for these motors in automotive applications, facilitating their introduction in starter-generator applications. PM brushless machines have therefore been considered [85,100], even switched-reluctance [85], although induction appears to have a significant lead in challenging the Lundell [85,[97][98]100,102], reaching production [104][105]. Although both PM and induction machines are well adapted to the application, induction seems to have an edge due to several factors: Primarily, lower cost (no magnets); also, given the very wide speed range (1 to 10), larger than in hybrid and electricpropulsion applications, PM machines lose some of their efficiency advantage as many operating points require field weakening in which operating mode the PM machine is a field-excited machine just like the induction.…”

The electrification of the automobile has a long history. Electric and hybrid vehicles are actually only a small part of it, albeit presently the most visible and the one getting the most attention in popular media. This paper will focus on the rest of the story, that is, aspects of transportation electrification other than hybrid or fully-electric propulsion systems. Recent progress (last 10-20 years) and current work on the electrification of road transport, from chassis to powertrains, will be reviewed with a focus on electromechanical systems. In the process, the numerous challenges engineers have overcome or have yet to solve will be highlighted, thus illustrating the many different ways electrical engineering is making its mark in providing more performant, more efficient, safer, and more pleasant means of personal transportation.

A transmission from the engine crank to the main transmission with variable reduction ratio is desirable for the hybrid electric vehicles, especially for micro/mild hybrid vehicles with auto start-stop function, for the sake of reducing the design requirements for integrated starter-generator and thus reducing the cost. This paper presents a solution to the issue by introducing a Controller-Free Ratio-Variable gearbox. Unlike other solutions, the proposed gearbox avoids from using actuators to change gear ratios but realize the function in a purely mechanical and fully automatic way. This feature reduces system complexity and improves system stability, as electronic-based info sensing and actuating are not as robust in the engine compartment. Also, the feature allows to change gear ratio faster and thus better protecting integrated starter-generator from over speeding. In this paper, the principle of the gearbox is explained and its performance under different conditions is studied.
