This paper makes an effort to define an optimal electrical architecture for a 12V BSG system for a mid- sized diesel engine, with the help of functional validation tests and specific test cases developed by the authors. The first few sections of the paper explain various modes of a 12V BSG hybrid operations namely-ESS, torque assist and recuperation on a reference vehicle. Set of test cases have been developed to explain 12V BSG behavior as a DC motor during ESS and torque- assist mode of operation and as a 3-phase generator during regenerative coasting mode. In the final section, an optimized electrical architecture of 12V BSG system is proposed for mid-sized diesel engine with manual transmission, based on objective measurement of test cases and a Pugh Comparison matrix of various feasible architectures.

“…This may then be used as a basis for the development of the more advanced engine control strategies. These may include the model-predictive control-based idle speed control system [32], characterized by superior engine speed control performance, or a selforganizing fuzzy control system coupled with the equivalent consumption minimization strategy based on BSG utilization, which has shown about 15% fuel consumption reduction compared to the conventional automotive power train [33].…”

In order to meet the increasingly stricter emissions’ regulations, road vehicles require additional technologies aimed at the reduction of emissions from the internal combustion engine (ICE). A favorable solution from the standpoint of costs and simplicity of integration is a 48-V electrical architecture utilizing a low-voltage/high-power induction machine, which operates as the so-called engine belt starter generator (BSG) coupled via a timing belt with the ICE crankshaft within a P0 mild hybrid power train and used for starting up and boosting of the ICE power output, as well as for recuperating kinetic energy during vehicle deceleration. The aim of this work was to design a vibration damping system for the belt transmission within the so-called front end accessory drive (FEAD), which couples the BSG with the ICE crankshaft and to test the control system by means of simulations for realistic operating regimes of the P0 mild hybrid power train in order to show the functionality of the proposed approach in terms of mild hybrid vehicle performance improvement. Simulation results have pointed out effective attenuation of belt compliance-related vibrations using the proposed active damping control, with vibration magnitude reduced between three and five times compared to the default case during engine start-up phase. They have indicated the realistic belt slippage effects during engine start-up phase and have illustrated the effectiveness of the FEAD torque boosting capability with 30% gain in acceleration during vehicle launch.

“…Belt-driven starter generators (BSGs), integrated starter generators and fully mixed drive motor and generator systems (Bonthu et al , 2016) are the three modes of HEVs system. The BSG is a micro-oil-electric hybrid system, which can reduce the fuel consumption, emissions and application costs (Guan et al , 2015). Consequently, the BSGs are suitable for HEVs.…”

Purpose Inductance, torque and iron loss are the key parameters of switched reluctance motors for belt-driven starter generators. This paper aims to present the analysis of a segmented rotor switched reluctance motor (SSRM) with three types of winding connections for hybrid electric vehicle applications by using a two-dimensional finite element method. Design/methodology/approach The rotor of the studied SSRM consists of a series of discrete segments, while the stator is made up of exciting and auxiliary teeth. First, the concept and structures of the different winding connections are introduced. Then, the magnetic flux path of the three types of winding connections for the SSRM is described. Second, the magnetic flux distributions in the three parts, i.e. the stator yoke, the stator tooth and the rotor segment, are described in detail to calculate the iron losses. Third, three SSRMs with the different winding arrangements are analyzed and compared to evaluate the distinct features of the studied SSRM. The analysis and comparison mainly include self-inductances, mutual inductances, phase currents, output torque and iron loss. Findings It is found that the self-inductances of the three types of winding connections are almost equal, and only the SSRM1 has a positive mutual inductance. In addition, the current waveforms of SSRM1 and SSRM2 are regular. However, it is irregular in SSRM3. It is shown that SSRM1 has better characteristics, such as higher output torque, high power density, lower torque ripple and iron loss. Originality/value This paper proposes and analyzes three novel winding connections for the SSRM to provide guidance for enhancing the output torque and reducing the iron loss to achieve high efficiency.
