In itself, there is a very thin boundary layer physically adsorbed to the bearing surface. When the bearing
clearance is far larger than the thickness of this layer, the boundary layer effect in the bearing is negligible, and conventional
hydrodynamic lubrication theory just a...
Next-generation accurate vehicle localization and connectivity technologies will enable significant
improvements in vehicle dynamics control. This study proposes a novel control function, referred to as pre-emptive braking,
which imposes a braking action if the current vehicle...
This study attempts to clarify the characteristics of light-duty truck collision accidents involving pedestrians
during right-turn maneuvers by analyzing actual pedestrian accident data in Japan. Evidence differences were observed
between the daytime and nighttime. The number ...
For vehicle state estimation, the conventional Kalman filter performs well under the Gaussian assumption, but
in the real non-Gaussian situation (especially when the noise is non-Gaussian heavy-tailed), it shows poor accuracy and
robustness. In this paper, an extended Kalman f...
A good understanding driver behavior is significant in the development of chassis control system and
autonomous vehicles. To better simulate human drivers, the driver model with the local path rolling planning decision is
developed based on model predictive control algorithm. ...
The possibility of a passively regenerated partial CDPF is investigated to reduce PM emitted from in-use
agricultural machinery. A typical partial CDPF does not have high filtering efficiency because some open channels exist in
the filter; these prevent damage to the filter du...
This paper employed finite-element simulation together with a human body model (HBM) - THUMS to study
the head injury risk of a pedestrian involved in a frontal impact with a sedan car. While previous studies have gained an
intensive understanding of the effects of various fac...
In vehicles with driving assistance systems, the responsibility of driving still lies with the driver. Therefore,
active safety systems follow a design principle of avoiding intervention as long as possible. Decision making using this
principle requires collision avoidance wit...
Lubricants, such as any types of greases and oils, are usually used to reduce the effect of friction. However,
they also have multifunctions that increase the overall performance and application life. To clarify how lubricants decrease
friction and reduce friction-related issu...

real-world environments, such as urban env...
Due to growing demand for driving comfort in cars, Air Springs are increasingly being installed in upper
mid-range segment. The stiffness of an Air Spring is significantly influenced by its enclosed air volume, larger volumes
lead to softer spring systems. The decreasing insta...
