One source of accidents when driving a vehicle is the presence fog. Fog fades colors and reduces contrasts in scene with respect to their distances from driver. Various camera-based Advanced Driver Assistance Systems (ADAS) can be improved if efficient algorithms are designed for visibility enhancement road images. The algorithm proposed [1] not optimized In this paper, we reformulate problem as inference local atmospheric veil constraints. thus becomes particular case. From new derivation,...

One source of accidents when driving a vehicle is the presence homogeneous and heterogeneous fog. Fog fades colors reduces contrast observed objects with respect to their distances. Various camera-based Advanced Driver Assistance Systems (ADAS) can be improved if efficient algorithms are designed for visibility enhancement road images. The algorithm proposed in not dedicated images thus it leads limited quality results on this kind. In paper, we interpret as inference local atmospheric veil...

This paper presents a modified potential field method for mobile robots and intelligent vehicles local navigation. The approach overcomes the well-known artificial (APF) issue, which is due to minima that induce standard APF trap in. Thus, no longer useful in such cases. advantage of new proposed method, as opposed those resort global optimization methods, low computing time lines up with standardA-Star (A∗) method. strategy consists looking practical path field-according gradient descent...

This paper discusses driving system design based on traffic rules. allows fully automated in an environment with human drivers, without necessarily changing equipment other vehicles or infrastructure. It also facilitates cooperation between the and host driver during highly driving. The concept, referred to as legal safety, is illustrated for highways distance keeping, intelligent speed adaptation, lane-changing functionalities. Requirements by safety perception control components are...

Accurate and reliable vehicle localization is a key component of numerous automotive Intelligent Transportation System (ITS) applications, including active safety systems, real time estimation traffic conditions, high occupancy tolling. Various critical applications in particular, such as collision avoidance or mitigation, lane change management emergency braking assistance rely principally on the accurate knowledge vehicles? positioning within given vicinity.

In this paper, a novel approach for improving vehicular positioning is presented. This method based on the cooperation of vehicles by communicating their measured information about position. consists two steps. first step, we introduce our cooperative map matching method. uses V2V communication in ad hoc network (VANET) to exchange global system (GPS) between vehicles. Having precise road map, can apply constraints other own process and acquire significant improvement positioning. After...

Truck platooning is a promising technology in freight transport. To commercialize truck as early possible, its evaluation urgent need. For evaluation, simulation platforms play crucial role. However, there has not been platform to meet the needs of various stakeholders, including Original Equipment Manufacturers (OEMs), Freight Operators (FOs) and Transportation Management Administrations (TMAs). fill research gap, this paper proposes next-generation platform. It integrates traffic...

In this paper, the problem of tracking desired longitudinal and lateral motions for a vehicle is addressed here. Let us point out that "good" modeling often quite difficult or even impossible to obtain. It due example parametric uncertainties, mass, inertia interaction forces between wheels road pavement. To overcome type difficulties, we consider model-free control approach leading "intelligent" controllers. The motions, on one hand, driving/braking torques steering wheel angle, other are...

Accurate localization of a vehicle is challenging task as GPS available on the market are not designed for lane-level accuracy application. Although dead reckoning helps, cumulative errors from inertial sensors result in integration drift. This paper presents new method based data fusion. An accurate digital map lane marking used powerful additional sensor. Road markings detected by processing two lateral cameras to estimate their distance vehicle. Coupled with EKF filter it improves...

Advanced driving-assistance systems (ADAS) have recently received an increasing attention from the car industry. ADAS development represents a considerable effort to obtain efficient and reliable systems. Driving several million kilometers is necessary validate system. Thus, there are strong needs ease validation processes. In this context, computer simulation techniques candidate solution problem since running digital scenarios saves time, money human resources. Up until now, simulators...

IEEE 802.11p is the new standard for inter-vehicular communications (IVC) using 5.9 GHz frequency band; it planned to be widely deployed enable cooperative systems. uses and performance have been studied theoretically in simulations over past years. Unfortunately, many of these results not confirmed by on-tracks experimentation. In this paper, we describe field trials technology with our test vehicles. Metrics such as maximum range, latency frame loss are examined.

Fast 3D reconstruction with semantic information on road scenarios involves issues of geometry and appearance in the field computer vision. An important idea is that fusion would boost performance each other. Stereo cameras RGB-D sensors are widely used to realise trajectory tracking, but they need heavy computation cost storage a dense way. Moreover, lack flexibility seamless switch between various scaled environments, i.e., indoor outdoor scenes. Besides, autonomous vehicle benefit from...
