The Hybrid Electric Vehicles (HEVs) have additional powertrain components compared with conventional
vehicles. Thus, to design a Vehicle Thermal Management System (VTMS) architecture and control strategy for a new HEV
powertrain, it is necessary to analyze the energy balance i...
Among road traffic deaths, pedestrian accounted for 22 % of all fatalities in the world, 26 % in Europe, and 22
% in the U.S. To investigate the injury risk of the high-stature population, a Finite Element (FE) model corresponding to a
male 95th percentile (M95) pedestrian was...
Although the automotive industry has been among the sectors that best-understands the importance of drivers’
affect, the focus of design and research in the automotive field has long emphasized the visceral aspects of exterior and interior
design. With the adoption of Advance...
For developing automotive industry, one of the focusing point is reduction of engine friction level to decrease
both engine emissions and fuel consumption. Important part of researchers have focused on cold engine start period, which
has higher friction loses. Shorter warm up ...
In order to study the electric power steering system (EPS) which is suitable for the steering characteristics of
commercial vehicles, the effect of weight on steering performance is analyzed, and a dual-motor full-weight EPS system is
proposed. Firstly, the full-weight assist ...
In this paper, a model for a prediction of conducted emission from vehicular PMSM-drive braking system is
presented. The proposed model is based on the high-frequency circuit model combined with EM simulation. The parameter
for high-frequency circuit modeling is derived from t...
An in-house simulation program is developed that can conveniently be utilized to predict characteristics of
compressible flow in flow network systems comprising multiple flow components. The program consists of two parts, the
flow analysis for computing velocity, pressure, and...
To reduce the calculation time needed to determine the optimal path, the form of the road and the path of an
autonomous vehicle were linearized; additionally, among multiple obstacles, only those that were potentially dangerous were
chosen. By considering the movement of movin...
Since the mode transition performance of power-split DHT (Dedicated Hybrid Transmission) are directly
influenced by torque dynamic characteristic of the brake, the brake pressure should be controlled accurately. In this paper, a
dynamic model of brake and its pressure regulati...
Owing to stricter environmental regulations and greenhouse gas reduction targets, hybrid electric vehicles
(HEVs) have marked a remarkable increase in market share to replace internal combustion engine vehicles (ICEVs). Among
HEVs, powersplit HEVs have attracted increasingly h...
In this study, an optimum design for the combustion system of a genset diesel engine was conducted by using
Design for Six Sigma (DFSS) methodology. As a result of this study, the best combination of design parameters to minimize
the fuel consumption of the genset diesel engin...
In this study, the crash-worthiness of a regular Centurion 2M barrier, which is a type of portable water-filled
barrier (PWFB), is evaluated under different collision conditions. A numerical model of the regular Centurion 2M barrier,
consisting of a plastic shell and water, wa...
The Reinforced Thin-walled Hat-shaped Section (RTHS) beams is widely used in automobile body. The
bending collapse characteristic of the RTHS beams plays an important role in the crashworthiness. The paper focuses on the
theoretical analysis on the bending collapse characteris...
This paper investigates the effects of Hydrotreated vegetable oil (HVO)-diesel blends on combustion
characteristics under various ambient oxygen concentrations and ambient temperatures in a constant volume combustion
chamber (CVCC). Combustion characteristics were presented in...
Construction equipment has consumed a lot of energy with a high workload compared to commercial vehicles
of the same class. So, fuel efficiency is one of the important indicators of merchantability of the construction equipment.
Especially, because forklift has been generally ...
In this paper, an active front steering (AFS) controller with a new variable steering ratio (VSR) map is proposed
to enhance the vehicle stability and consider the driver’s steering comfort. The properties of the steering sensitivity and the
yaw rate gain are investigated and...
Although a 5-cycle testing was adopted to address the gap between the reported fuel economy from
certification tests and fuel economy during real-world driving, the gap still remains and is difficult to be resolved without the
consideration of the fuel consumption influencing ...
Polyoxymethylene dimethyl ethers (PODE) has good application prospects as an alternative to diesel fuel with
a great potential to achieve clean combustion on diesel engines. In current study, the effects of PODE/diesel blends with PODE
volume fraction at 10 %, 20 % and 30 % on...
In recent years, interest in smart and green vehicles has increased. There are many cases where engine net
torque related control is performed when building smart and green car systems. Speed tracking control in autonomous driving,
or optimal transmission shift control is an e...
This work has numerically analyzed the structure of spray flames with various ambient oxygen concentrations.
To realistically predict the spray evaporation characteristics in the high-pressure diesel-like environment, the present study has
employed the high-pressure effective ...
