This paper presents a novel technique by which non-Gaussian vibrations are synthesized by generating a sequence of random Gaussian processes of varying root-mean-square (rms) levels and durations. The technique makes use of previous research by the authors which shows that non-Gaussian vibrations from wheeled vehicles comprise of a sequence of Gaussian segments. Synthesis is achieved by creatin...

OBJECTIVE To assess the effect of driver dependent factors on the risk of causing a collision for two wheeled motor vehicles (TWMVs). DESIGN Case control study. SETTING Spain, from 1993 to 2002. SUBJECTS All drivers of TWMVs involved in the 181 551 collisions between two vehicles recorded in the Spanish registry which did not involve pedestrians, and in which at least one of the vehicles ...

This paper reports a methodology for inferring terrain parameters from estimated terrain forces in order to allow wheeled autonomous vehicles to assess mobility in real-time. Terrain force estimation can be used to infer the ability to accelerate, climb, or tow a load independent of the underlying terrain model. When a terrain model is available, physical soil properties and stress distribution...

Models, simulators and control strategies are required tools for the conception of secure and comfortable vehicles. The aim of this paper is to present an efficient way to develop models for dynamic vehicle, focusing on a two wheeled vehicles whose body involves six degrees of freedom. The resulting model is sufficiently generic to perform simulation of realistic cornering and accelerating beha...

This paper considers the problem of engine-to-slip dynamics modeling in a sport motorbike. Instead of using the classical approach of multibody modeling, this work takes the challenge of directly estimating the input/output slip dynamics by black-box identification, using data collected with experiments specifically designed for this purpose. The proposed identification protocol allows to deriv...

Autonomous and teleo erated mobile robots require an ccurate knowledge of their spatial location in order to accomplish many tasks. Many mobile robots make use of dead reckoning navigation because of its simplicity, low cost and robustness. Although dead reckoning navigation has been used for centuries for ships and wheeled vehicles, the application to a walking machine is novel. Since walking ...

Wheeled and tracked vehicles are mainly suitable for relatively flat terrain. Legged vehicles, on the other hand, have the potential to handle a wide variety of terrain. This article presents a new locomotion concept, adapted to both flat and complex rough terrain by combining the advantages of wheeled and legged vehicels. MATE-1 is a bipedal robot equipped with two special grippers which provi...

The method of testing vehicles for dynamic position stability has been improved, which makes it possible to assess their lateral when driving on irregularities. coefficient is proposed use as an assessment criterion. application the developed allows obtain in real time during operation transport means.
