This paper investigates asymmetric hardening behavior of the magnesium alloy sheet of AZ31B at different
strain rates when deformation is large. Tensile tests are carried out at the quasi-static state of 0.001 s–1 and the intermediate
strain rate of 100 s–1 utilizing the In...
Reconstruction of car accidents is a complex task, with many unknown variables. Among the parameters used
to assess the accident severity, in case of a frontal collision between two vehicles, are the change in velocity (delta-v) and the
Energy Equivalent Speed (EES). The EES i...
This paper proposes a novel supervisory control for a parallel hybrid electric vehicles (HEVs) with a
transmission-mounted electric drive (TMED). The proposed control includes an optimal power distribution algorithm that uses
a modified equivalent consumption minimization stra...
This paper focuses on the path-tracking controller design for autonomous ground vehicles (AGVs) using fourwheel
steering (4WS) and direct yaw-moment control (DYC) systems. In order to deal with the parametric uncertainties, a
linear parameter-varying (LPV) H∞ controller is de...
This study aims to reduce the severity of injuries caused by and the frequency of rear-end vehicle collisions.
A better collision prediction method is proposed by means of millimeter-wave radar sensors able to rapidly detect potential
collisions and alert drivers. Implementati...
This research investigates the spray characteristics of gasoline-biodiesel blended fuels (GB), which expected to
be utilized in a gasoline compression ignition engine. Commercial gasoline blended with 0 ~20 % by volume of biodiesel,
called GB00 - GB20, were used to experimen...
For predictive powertrain control, accurate prediction of vehicle speed is required. As vehicle speed prediction
is affected by the driver’s response to numerous driving conditions under uncertainty, the development of an accurate model
is quite challenging. This paper propos...
The lasting high fuel cost has recently inspired the resurgence in drag reduction research for vehicles, which
calls for a thorough understanding of the vehicle wake. The acknowledged MIRA fastback vehicle model is characterized by
similar real vehicle geometry, thus it is esp...
Today, the use of electric vehicles (EVs) is increasing. Electric motors, which are used as the power source in
EVs, have better torque-speed characteristics than traditional engines. However, electric motors also have a low speed torque
limitation; moreover, their energy effi...
Hybrid gears made of steel and fiber-reinforced polymeric composite material are recently attracting electric
vehicle designers’ attention due to their possible advantages such as lightweight and lessened transfer of noise and vibration
for automotive transmissions. Polymeric...
The aim of this study was to establish a test method with improved reliability and reproducibility for the
accelerated weathering test of automotive interior materials. For this purpose, this study measured the spectral power
distribution (SPD) of the glass used in actual vehi...
The effects of wheel rotation, rim coverage area, fan spokes, spoke sharpness, and tread pattern on the flow
field and drag coefficient of a passenger vehicle were investigated. Force measurements and wake surveys were taken on a 1/
5th scale passenger vehicle at a Reynolds nu...
A simulation model of a diesel engine is widely applied to evaluate the engine controller before a vehicle test
because controller error can be observed by the engine model. For diesel engine modeling, an adiabatic model is commonly
used to express intake manifold pressure bec...
Tire Inflation Pressure Loss Rate (IPLR) test is a widely accepted test method to evaluate the tire pressure
retention performance, which helps increase fuel economy and prevent premature tire failures. At present, an IPLR test usually
lasts for several months, which greatly r...
This research aimed to develop the 3D finite element model of non-pneumatic tire (NPT) for designing the
proper radial spoke. The NPT was cut using waterjet cutting technique to prepare the appropriate test specimens. The
hyperelastic constitutive models were used to model the...
This paper mainly concerns the thermo-mechanical analysis to evaluate the process parameters in the hot press
forming with the 22MnB5 sheet such as the austenitization temperature, transport and quenching time for enhancing the
efficiency in the production cycle. It is noted t...
This paper describes steering returnability by analyzing forces applied to kingpin axis in limit cornering
conditions. The steering returnability is related to forces applied to kingpin axis. These forces are classified by its source: Tire
force and steering force. Tire force ...
Urea selective catalytic reduction (SCR) is the primary technology used to reduce the nitrogen oxides (NOx) of
diesel engine exhaust. To meet the requirements of an SCR system, a novel type of miniature diaphragm pump was designed.
Based on the theory of large deflection of an...
The high power consumption of the automatic transmission oil pump has led to the undertaking of efficiency
improvement studies over a number of decades. For the unique idea of the present paper, a single automatic transmission oil
pump was adopted to satisfy the requirements o...
The main purpose of this research work is to demonstrate the effective plasma of capacitive discharge ignition (CDI) comparing with conventional ignition discharge. A constant volume combustion chamber (CVCC) with a volume of 450 cm3 is developed to study thermochemical combusti...
