About the Edition

We present four vehicle localization (position estimation) algorithms. These algorithms can be broken into two classes: those which minimize the mean square error in the position estimates (i.e. the Kalman filter and the nonlinear least squares constrained algorithms), and those which minimize the maximum level of error in the position estimates (i.e. the Hinfinity filter and the constrained minimax algorithm). We show that gains in accuracy and reliability can be achieved over existing GPS-based approaches by making use of radio ranging based inter-vehicle distance measurements. Also, we show that the accuracy of previously proposed radio ranging based localization can be improved upon by taking into account additional information that is available to vehicles (e.g. digital road maps: vehicle kinematics). Then, after showing the benefits of using our algorithms, we present a detailed mathematical analysis and series of experiments that highlight the advantages and disadvantages of each algorithm.

The present study addresses a solution to the position and orientation estimation problem of vehicles in ad-hoc vehicle networks using decentralised filtering. Specifically, a distributed filter operating in a cooperative federated structure for enhancing the estimation accuracy of vehicles state over unreliable wireless communication networks subject to uncertain and limited measurements is Cited by: However, if the target vehicle is non-cooperative and does not have the ability to maintain attitude control, or transmit attitude knowledge, the docking becomes more challenging. This work presents a nonlinear approach for estimating the body rates of a non-cooperative target vehicle, and coupling this estimation to a tracking control scheme.

The vehicle position estimation problem can be formulated as follows. Consider a cluster of n vehicles labeled 1,2, n at unknown distinct locations in some physical region at time t. For each vehicle, we establish a map of the relative position of its neighbours.

More explicitly, we estimate the true relative positions of the vehicles, A, defined as. Cooperative or multi-agent estimation within the vehicular network has been studied for applications such as traffic flow estimation [75] and vehicle positions [21,62, 82].

Cooperative Position Estimation. The research begins with the development of a cooperative navigation system based on the measurement of vehicle position relative to shared landmark position estimates. Each vehicle in the network locates landmarks using it's on-board vision system and transmits the data to all other system by: 1.

We present a novel cooperative vehicle position estimation algorithm, which can achieve higher levels of accuracy and reliability than existing GPS based positioning solutions by making use of.

Each vehicle uses information obtained byGPS and sensors of differentvehicles at different time to estimate positions in the situation all the vehicles can not use GPS and sensors.

Also, vehicles share the most accurate estimation according to accuracy of estima. We present a novel cooperative vehicle position estimation algorithm, which can achieve higher levels of accuracy and reliability than existing GPS based positioning solutions by making use of inter-vehicle distance measurements taken by a radio ranging technology.

This is referred to as cooper-ative localization (CL). Due to the absence of the GPS signal underwater, the correct estimation of its position is a challenge for submerged vehicles.

One promising strategy to mitigate this problem is to use a group of AUVs where one or more assume the role of a beacon vehicle which has a very accurate position estimate due to an expensive navigation suite or frequent surfacings. These warnings may include information about upcoming roadworks, or a change in speed limit using the vehicle-to-infrastructure communication.

Cooperative vehicles provide drivers with degree awareness of similarly equipped vehicles and infrastructure, within a range of approximately m. A new cooperative localisation method based on the Bayesian framework is proposed to obtain accurate and reliable vehicle localisation in intelligent transportation system applications.

The new position estimation is achieved by the fusion of the filtered global positioning system (GPS) data, the inter-vehicle distance, and bearing : Xiaolin Song, Yifei Ling, Haotian Cao, Zhi Huang.

more accurate position estimate of the vehicle. However, if the object of interest is moving, the UAV may not be able to complete the necessary maneuvers to gain a more accurate estimate.

In this chapter, we present a vision-based estimation and tracking algorithm that exploits cooperation between multiple UAVs in order to provide accurate. GPS is a well-known position system but it suffers from multipath effect and non-line of sight in tunnel environments.

Relative Position or sometimes called cooperative localization is an alternative position estimation. It utilizes different forms of v2x communication to exchange position, distance, direction, and velocity parameters.

Abstract. As autonomous ocean vehicles become more affordable and reliable, applications of multivehicle teams become more feasible. Cooperative vehicle target tracking is a promising application since in many sport, military, and biological endeavors cooperative strategies have proven themselves to be advantageous over noncooperative by: 1.
