- Abstract
- Presented in this paper is a 48 V-powernet-based powertrain structure with a front-wheel drive system that includes an engine and a 48 V BSG and a rear-wheel drive system driven by a traction motor without a mechanical link to the front-drive axle. The power distribution algorithm of the hybrid supervisory controller includes an electric drive mode by the rear-wheel drive motor as well as a hybrid electric control mode between the engine and the two drive motors. The results of the fuel economy simulation for the 4 WD 48 V mild hybrid system that was performed in the study are presented in this paper, along with the results of the analysis of the varying of the capacity of the rear-drive motor from 5 to 15 kW. The fuel efficiency improvement of the front engine is also compared with that of the BSG.This paper introduces a power distribution algorithm for the mild hybrid drive system model, and presents a design guideline for selecting the capacity of the rear-drive motor based on the simulation results for fuel economy and efficiency improvement.
