In this paper, we described about evaluation of human sensibility using park assist system of the commercial vehicle. The perpendicular parking and parallel parking have been carried out as a user test and subjects are classified as beginning drivers, drivers with less than 1 year experience and over 3 years experience. As a result, parking duration of beginning drivers and drivers with less than 1 year experience who use automatic parking assistance system is similar to drivers with over 3 years experience. However error occurred according to sensor position and distance between vehicle and parking space. And also it occurred that the vehicle leaves from parking line or does not recognize the parking space. Therefore, if we improve its completeness by compensating problems that came up from this evaluation and distribute the automatic parking assistance system, it is expected that the park assistance system is to help driver providing convenience of parking.
Prior to the development of a system that considers the safety of the occupant, research of the behavior of the occupant state is necessary. In addition, the information about the occupant body type, the type of the vehicle and its condition is also important. It is necessary to study the behavior of the state of the occupant in an environment where the internal structure of the vehicle is taken into account. In this paper, a multi-body model for analysis of the occupants in various environment is suggested. It is based on Madymo (HybridII) and the modeling is done by matching the value of the result. Error for the match is ± 1.5cm. Suggested model can be used to analyse the occupant for variety of environments. The new model can be applied through the matching of the result value.
<P>Cosmological transverse momentum fields, whose directions are perpendicular to Fourier wave vectors, induce temperature anisotropies in the cosmic microwave background via the kinetic Sunyaev-Zel'dovich (kSZ) effect. The transverse momentum power spectrum contains the four-point function of density and velocity fields, <delta delta nu nu >. In the post-reionization epoch, nonlinear effects dominate in the power spectrum. We use perturbation theory and cosmological N-body simulations to calculate this nonlinearity. We derive the next-to-leading order expression for the power spectrum with a particular emphasis on the connected term that has been ignored in the literature. While the contribution from the connected term on small scales (k > 0.1 h Mpc(-1)) is subdominant relative to the unconnected term, we find that its contribution to the kSZ power spectrum at l = 3000 at z < 6 can be as large as ten percent of the unconnected term, which would reduce the allowed contribution from the reionization epoch (z > 6) by twenty percent. The power spectrum of transverse momentum on large scales is expected to scale as k(2) as a consequence of momentum conservation. We show that both the leading and the next-to-leading order terms satisfy this scaling. In particular, we find that both of the unconnected and connected terms are necessary to reproduce k(2).</P>
It is possible to improve the performance of the existing autonomous driving functions relying solely on environmental sensors via V2V communication. In this paper, a cooperative autonomous driving algorithm was developed by using V2V communication to allow a safe and comfortable convoy driving with the preceding vehicles. The algorithm implements CACC when the convoy is maintained with the preceding vehicle. In addition, the algorithm has been designed to handle situations that can lead to dangerous conditions when handled only by a CACC logic, such as when the convoy changes its formation by a merging or leaving vehicle in front. For validation, simulation was carried out on different scenarios, and the results confirmed that the proposed algorithm can significantly improve string stability during convoy driving compared to ACC and CACC algorithms. It was also confirmed that the proposed algorithm can provide enhanced comfort by completing transient convoy maneuvers with minimum control effort.
