In automotive industry, materials having excellent resistance to corrosion, good wear resistance and high
strength to weight ratios are important. In accordance with the required properties; aluminum, nickel, titanium, magnesium
and their alloys are mostly used in this industr...
Repeated engagements in dry clutch systems could yield remarkable increase of clutch disk temperature. In dry
clutch based transmissions like Automated Manual Transmissions and Dual Clutch Transmissions the overheating leads to
poor control of gearshift quality due to unpredic...
Vehicle dynamics plays a significant role on the formation of a vehicle platoon, especially at high speed
condition. This paper proposes a distributed platoon formation framework for homogeneous autonomous vehicles which takes
the vehicle dynamics into consideration. The bound...
In order to increase the durability of fuel cell stack, various operating technologies such as voltage cut-off and
lean air operation was verified. With an application of upper voltage cut-off, cell performance loss was effectively diminished,
which suggests that a formation o...
In automotive design, the study of the water thin layer over a car due to rain is becoming increasingly
important: the challenge is to obtain a way to describe the behavior of the water over a vehicle in rainy conditions and its
interactions with wipers and drainage systems, t...
Autonomous cars have become a reality due to breakthroughs in technology enablers such as embedded
computing systems and artificial intelligence. Automated platooning, which can be employed in autonomous cars, allows
grouping of vehicles into platoons. Using this technology in...
The reduction of energy consumption and environmental impacts of road vehicles is always a major design
objective. Many investigations suggest that reducing aerodynamic drags such as pressure drag and skin friction drag is a more
efficient method than engine modification in ac...
Urea SCR technology has been widely used to reduce NOx emissions of diesel engines. Despite remarkable
development for decades, more advanced control and optimization of urea SCR systems are still required as global NOx
emissions standards are expected to become more stringent...
As an important part of continuously variable transmission (CVT) vehicle power transmission system, drive,
neutral and reverse (DNR) wet clutch has the function of transmitting or interrupting vehicle power. However, due to the
complex and variable working conditions of the cl...
When a vehicle is parked under the summer sun, to avoid the passenger discomfort caused by high cabin
temperature, the performance of forced ventilation, which is called pre-ventilation, using a solar sunroof integrated with a
photovoltaic (PV) cell to reduce cabin thermal loa...
In this paper, the formability of E-FORM magnesium alloy sheet (as one of recent alloys for automotive
magnesium sheets) is analyzed based on the comparison between the results of actual magnesium (Mg) roof forming and those
of finite element (FE) simulations. The FE model con...
For the multi-cylinder gasoline engine, the consistency among cylinders is an important index to affect the
engine emission and the engine power. In this paper, an individual cylinder air-fuel ratio (A/F) control method for a fourcylinder
camless engine with the electromagneti...
Detection of drivers’ states is the essential technology not only to prevent car accidents related with their state
but to develop self-driving car. Detecting technology generally uses two types of methods; physiological measures and
vehicle-based measures. Vehicle-based meas...
Accurate electromagnetic force control in a high speed on/off valve actuator (HSVA) can improve the
performance of a vehicle braking system, and an accurate theoretical model is the key to smoothly controlling the high speed
on/off valve. Therefore, a nonlinear model of an HSV...
In this research, recognition sensors are used for tracking the outside world along with a steering assistance
model that reduces delays inherent in the human cognition, decision, and operation decision-making chain, thereby
minimizing vehicle behavior delay with respect to th...
This paper proposes a novel localization method based on a camera that can estimate the absolute position of
a vehicle using a public online database of road signs. The estimated absolute position near a road sign is used to compensate
the drift error of visual odometry (VO). ...
In this study, two kinds of control methods for the transient operation of an engine test bench for heavy-duty
vehicles were applied in the JE05 test cycle and World Harmonized Transient Cycle (WHTC) test conditions in order to
evaluate the controllability of transient operati...
As electric vehicle (EV) emerges, it is important to understand how driver’s driving behavior is influencing
power consumption in an electric vehicle. Driver’s personal driving behavior is usually quite distinctive and can be recognized
by means of driving patterns after so...
This paper proposes a new methodology based on the multi-port network theory to predict the vehicle-level
electromagnetic compatibility performance. The original EMC problem is firstly converted to a network by separating the
electrical large structures and electrical small co...
This paper proposes a control strategy of a hybrid energy storage system (HESS) based on simplified 2th-order
model. The HESS uses a bidirectional DC/DC converter to connect the supercapacitors (SC) with the battery. Two control
objectives, the output current of the SC during ...
