The enormous growth of vehicles on the roads increases the demand of different information and communication technologies to be extensively available over the road networks for better vehicle collision avoidance activities. The most occurring vehicle collision occurring in the present scenario is the forward vehicle collisions. The forward vehicle collision occurs when a vehicle tries to oversp...

This paper deals with the formation control of multiple vehicles, using a combination of dynamic surface sliding control and hybrid systems. Each vehicle must perform several manoeuvres, either independently, or in a coordinated fashion as part of a vehicle formation. A dynamic surface controller is designed for each manoeuvre. Switches between manoeuvres and communication protocols between veh...

Conventional positioning techniques based on GPS receivers are not accurate enough to be used with autonomous guidance systems. High accuracy GPS receivers can be employed, but the cost of the system would be very high. The alternative solution presented in this article is to combine the data provided by different positioning sensors using a Kalman filter. The described procedure also uses an o...

Nowadays positioning based navigation is an integrated part of our everyday’s routine. Hence, it is hard to succeed without a GPS based navigation system in a bigger city today. However, indoor positioning and navigation are still in their infancy, although these services would be desirable in many areas. One obvious application domain is vehicle navigation in a parking garage. The use of an in...

Vehicular positioning in urban canyons or covered areas such as car parks is a challenging issue due to the limited availability or lack of Global Navigation Satellite System (GNSS) signals. Tackling this problem, the concept of Cooperative Positioning (CP) has recently emerged for positioning or positioning enhancement in Vehicular Ad-Hoc Networks (VANETs). In the literature, CP techniques are...

This paper presents a framework to obtain pseudo lane-level positioning using low-cost GPS and driving event detection within the environment of vehicle-toinfrastructure (v2i) communication. In this context, pseudo means that lane level accuracy is achieved only under the assumption that v2i is available and there is no GPS outage. GPS errors can be categorized into common-mode errors and nonco...

Some new Advanced Driver Assistance Systems (ADAS) need on-the-lane vehicle positioning on accurate digital maps, but present applications of vehicle positioning do not justify the surcharge of very accurate equipment such as DGPS or high-cost inertial systems. For this reason, performance of GPS in autonomous mode is analyzed. Although satisfactory results can be found, in some areas GPS signa...

The concept of Cooperative Positioning (CP) has emerged recently to improve the quality of positioning, provided by Global Navigation Satellite System (GNSS), in terms of accuracy and availability. This is necessary to meet the requirements of the vehicular position-based applications such as collision avoidance, which cannot rely only on GNSS performance. CP systems are based on fusing data fr...

This work proposes the use of a hybrid acoustic and optical indoor positioning system for the accurate 3D positioning of Unmanned Aerial Vehicles (UAVs). The acoustic module of this system is based on a Time-Code Division Multiple Access (T-CDMA) scheme, where the sequential emission of five spread spectrum ultrasonic codes is performed to compute the horizontal vehicle position following a 2D ...

The Global Positioning System (GPS) has been widely used in land vehicle navigation applications. However, the positioning systems based on GPS alone face great problems in the so called urban canyon environments where the GPS signals are often blocked by high buildings and there are not enough available satellites signals to estimate the positioning information of a x. To solve the problem, a ...
