In order to predict the interior noise of the automobile in the low and middle frequency band in the design and development stage, the hybrid FE-SEA model of an automobile was created using hybrid FE-SEA method. The modal density was calculated using analytical method and finite element method; the damping loss factors of the structural and acoustic cavity subsystems were also calculated with a...

This article presents a local control approach to linear vehicle platooning. Linear platoon systems are sets of vehicles that use local or global perception capabilities to form a train configuration, without any hard grip element. Public transportation is beginning to interest in platoon systems as a technological base to conceive new services. The main problem related to platoon system’s cont...

This study evaluates the effectiveness of state child safety seat laws in the United States. Data for all fifty states for the period 1975 to 1994 are used. Pooled time series analysis is employed to estimate a model of the rate of fatalities suffered by children ages 0-5 years as occupants in automobile crashes. The occupant fatality rate for children 6-11 years of age is used as a comparison ...

This paper presents a method for analysis of automated highway throughput for AHS designs, including those with platooning. Simulation results are presented which show that increased information leads to higher throughput, and that a platooning design will have higher throughput than any individual vehicle design.

In this paper, we establish a basic dimension theory for rigid subanalytic sets, and we prove a Smooth Stratiication Theorem for such sets, in all characteristics.

THE PROBLEM: MOTORCAR MORALITY AND AUTOMOBILE AGEING Advances in modern technology mean that cars are living longer than ever before. This raises important end-of-road-life issues, as it becomes increasingly difficult to provide leaded fuel and shelter for our hydraulically challenged, ageing automobile population. The garage is full, and off-street parking is beyond the financial scope of most...

We show that a large class of non–metric, non–symplectic affine holonomies can be realized, uniformly and without case by case considerations, by Weyl connections associated to the natural AHS–structures on certain generalized flag manifolds.

The use of a mass balance equation assists in clarifying the contribution of automotive-emitted lead to the regional and global problems of the distribution of this element, by taking into account the physicochemical transformation processes operating on the lead during its transport along the various environmental pathways. The technical factors which govern the emission of such lead from auto...

In the standards about the contour dimension of automobile in most countries, the height difference of body symmetrical points or body inclination angle of automobile was specified. To improve the vehicle performance and operation safety, a measurement method of car body inclination angle was studied. According to the camera calibration and the distance between camera and automobile, the front ...
