A single contact point model was implemented in the open-source dynamics engine Chrono to provide a more accurate calculation of input slip quantities to the Magic Formula equations for non steady-state, or transient, slip cases. The model is formulated using a consistent ISO z-up x-forward coordinate frame, where the slip angle was shown to be invariant with the choice of coordinate system, bu...

Abstract By considering mandatory lane-changing as a collision avoidance measure, this paper presented the corresponding lane-change decision making and trajectory planning algorithm under an emergency scenario. Different from traditional in which are separated, they here coupled proposed related parameters dynamically adjusted whole process. In addition to feasibility analysis, time instance d...

In Vehicular Ad hoc NETworks (VANETs), trigger-based pseudonym change schemes play an important role in providing anonymity. However, the anonymity provided by these schemes usually is low mainly because the behavior of changing pseudonym is individual. Considering cooperation on changing pseudonym can enhance anonymity, in this paper, we give a general cooperation framework. As an application ...

In this paper we demonstrate a driver intent inference system (DIIS) based on lane positional information, vehicle parameters, and driver head motion. We present robust computer vision methods for identifying and tracking freeway lanes and driver head motion. These algorithms are then applied and evaluated on real-world data collected in a modular intelligent vehicle test-bed. Analysis of the d...

INTRODUCTION The relationship between the relative risk of a rear-end collision during a turn, merge, or lane change maneuver and the characteristics of the rear turn-signal configuration was examined using crash data from seven states in the United States. METHOD Rear turn-signal characteristics-including color, optics, separation, and light source-were identified for 55 vehicle models and u...

Based on a non-linear single track model which describes the dynamics of vehicle, an optimal path planning strategy is developed. Real time optimization is used to generate reference control values to allow leading the vehicle alongside a calculated lane which is optimal for different objectives such as energy consumption, run time, safety or comfort characteristics. Strict mathematic formulati...

We present an approach to prove safety (collision freedom) of multi-lane motorway traffic with lane-change manoeuvres. This is ultimately a hybrid verification problem due to the continuous dynamics of the cars. We abstract from the dynamics by introducing a new spatial interval logic based on the view of each car. To guarantee safety, we present two variants of a lane-change controller, one wi...

Electronic mirrors (E-mirrors) are camera-based mirrorless systems that have been considered as an alternative to conventional automotive rear-view mirrors. E-mirror location and size need be carefully determined provide safe preferred driving conditions. This study examined the effects of location, size, lane-change direction on lane change time, eye-off-road (EOR) mental workload, preference....

In the present paper, an effective support method for equipment operation under a dynamic environment is proposed. The proposed method presents operation instructions that the driver should be preparing to follow in the future. Using this method, the current and future states of the surrounding environment can be considered. The time change fuzzy set, which considers the state and time, to be u...

This paper reports on AnnieWAY, an autonomous vehicle that is capable of driving through urban scenarios and that has successfully entered the finals of the DARPA Urban Challenge 2007 competition. After describing the main challenges imposed and the major hardware components, we outline the underlying software structure and focus on selected algorithms. Environmental perception mainly relies on...
