By solving driver’s optimal handling input, this paper presents a novel Lane Changing Assistance System
(LCAS) which can provide guidance for driver’s lane changing behavior. In addition, vehicle handling inverse dynamics
method is proposed to solve driver’s optimal handl...
A ground-effect diffuser is an upwardly-inclined section of an automobile’s underbody which increases
aerodynamic performance by generating downforce. To understand the diffuser flow physics (force behaviour, surface and offsurface
flow features), we established the near-wake...
Hydrogen and oxygen fuel obtained from water electrolysis mainly contains H2 and O2, usually abbreviated to
HHO. The compositional characteristics of HHO were analyzed by gas chromatography-mass spectrometry (GC-MS). The
influence of HHO on the combustion process in the cylind...
The introduction of electromagnetic valve actuators (EMVA) benefits engine fuel economy, torque
performance and reduction of emissions. Meanwhile, it complicates the controller for the purpose of regulating the additional
freedom degrees of intake valvetrain, such as valve lif...
This paper proposes a method using screw theory to find the twist of a rigid body of a mechanism. For this, a
geometric method to determine the screws and reciprocal screws associated with kinematic joints and links is introduced. This
geometric method provides a simple way to...
This paper deals with a novel clutch mechanism for transmission applications, which aims at easy application
of the transmission as the micro-electric vehicle models expand in variety. The new mechanism actuated by the torque and
rotational inertia of the traction motor instea...
This paper presents an efficient and extensive exploratory search for lightweight side-door intrusion-bar
assembly design concepts using the approach previously developed by the author. The study aimed to discover latent
dependence or other relationships between the geometry b...
A vehicle disk brake, which has cross drilled hole patterns on a frictional surface for improving cooling and
braking performance, has propensity to cause crack problem under the harsh braking condition. In this study, the finite element
analysis by using ABAQUS was adopted to...
An accelerometer replaced an in-cylinder pressure sensor to detect the combustion status. The correlation
between the vibration on an engine block caused by direct combustion as well as the combustion status was analyzed. The
direct combustion vibration was determined. The dir...
The factors in fatal injuries to cyclists in collisions with five different types of vehicles were examined using
data from the Institute for Traffic Accident Research and Data Analysis in Japan for the period 2004 ~ 2013. The vehicle types
were sedans, minivans, box vans, lig...
The simulation of the liquid- and gas-phase properties of aerated-liquid jets in various quiescent and cross flow
conditions are presented in the study. For simplicity, water is used as the liquid for all test conditions. The effect of various
air-to-liquid ratios under super-...
This paper is devoted to the design and first implementation of a new head and neck safety device (NHNS) for
race of motorcycles. The system aims to mitigate the effects of crash forces acting along almost every direction with respect
to the head. The system is composed by a h...
To enhance the 48 V mild hybrid electric vehicle performance using a smaller capacity and lower voltage
battery than the full hybrid electric vehicle, a novel power management strategy needs to be established that considers the
characteristics and limitations of the components...
The semi-active suspension (SAS) system has been one of the most attractive topics due to its simplicity and
effectiveness in the control of vehicle dynamics. This research proposes a cuckoo search optimized proportional-integral–
derivative (CS-PID) strategy for the damping ...
This paper presents an analysis of the possibility to evaluate full vehicle crashworthiness simulations
automatically. Nowadays the evaluation of full vehicle crashworthiness simulations is done by only a few hard numerical
criteria and a lot of soft criteria which get evaluat...
The paper presents the change of the interior noise according to the lamination angles of the carbon fiber in the
carbon-fiber reinforced plastic (CFRP) laminated composite plate. In the previous paper, the charateristics of the sound
radiated from a CFRP plate was studied in ...
For an Extended-Range Electric Vehicle (E-REV), the misfire failure of the range extender can result in
working condition deterioration, mileage decrease, vibration and noise increase, and other adverse consequences. The
relationship of the shaft instantaneous angular speed (I...
