Information exchange for the purpose of creating situational awareness is the backbone of distributed systems that rely on communication. For example, connected vehicle safety systems rely on exchange of information between vehicles to allow each vehicle to create a real time map of its surrounding cars. These systems work by sampling the state of a physical process (vehicle trajectory) and communicating it to others. In this paper, we present a novel approach for communicating information of physical processes (such as vehicles) over a network using models of these processes. In this approach, traditional communication of data samples from a process is replaced by communication of models and model updates. This novel method allows each node in the distributed system to create a model-based view of its surrounding. The resulting model-based situational awareness map will have higher fidelity than only sample position information that is available through current methods. Using the example of a forward collision detection algorithm we demonstrate the significant performance improvement that is possible using this approach. We demonstrate that the system is able to maintain its performance at rates that are four times less than what current methods require.
In vehicular networking, the heavy traffic can cause channel congestion and hence, degrade the tracking accuracy of cooperative vehicle safety systems. To overcome this problem, a dynamic packet reception model that integrates the packets reception rate and the vehicle density is proposed. Then, a traffic- flow-based vehicle density estimation method is designed. This estimation method is capable of predicting the vehicle density in the scenario, where there exist strong interactions among the vehicles. Based on the vehicle density method, a dynamical transmission power control strategy is developed. This transmission power control strategy employs model predictive control to make the optimal control decisions based on the estimated vehicle density. Experimental analyses demonstrate that the dynamical power control strategy can greatly enhance the vehicle tracking performance of cooperative vehicle safety systems under dynamical traffic situation.
Cooperative vehicle safety systems (CVSSs) rely on vehicular networking for broadcasting state information in order to track neighbors' positions and, therefore, to predict potential collisions. In vehicular networking, a large number of vehicles compete for access to the limited channel resource, causing channel congestion. The vehicle tracking accuracy, which is the basis for CVSSs, therefore, can be heavily affected. Moreover, the available channel resources must be shared among vehicles in a fair way in order to maintain accurate tracking accuracy for each vehicle. To realize fair access to channel resources while maintaining an accurate tracking performance under conditions of dynamic vehicle density, in this paper, we present a distributed fair transmission rate control strategy, based on multi-agent model predictive control (MPC). We first propose a dynamic information dissemination rate model to capture the state information dissemination ability under conditions of dynamic vehicle density. Then, we present a multi-agent information dissemination model, in which each vehicle is controlled by a control agent that uses MPC and coordinates with its neighboring agents in order to determine its optimal transmission rate actions. We then design an augmented- Lagrangian-based distributed decision-making scheme to find the optimal transmission rate actions and, at the same time, reach an agreement on fair and efficient channel utilization among the vehicles. Simulation results confirm that the distributed transmission rate control strategy can guarantee fair access to channel resources while achieving the optimal vehicle tracking performance under conditions of dynamic vehicle density.
Scalability is one of the main challenges of cooperative vehicle safety (CVS) systems. In this paper, we describe a demonstration of the scalability solution that we have developed for CVS. The solution is an adaptive communication scheme for safety messages. The demo comprises of a demonstration of the rate control algorithm using recorded vehicle trajectories, and a live demonstration of the power control scheme using emulated interference. We show that the proposed algorithms are able to deliver considerably better performance than the baseline solution for CVS. The demonstration will use several DSRC units as well as visualization and simulation software for visualizing the network dynamics.
In the paper User adaptive design of active vehicle safety systems with regard to the driver behavior of elderly drivers the research project Evaluation of active vehicle safety systems and components in regard to their safety impact on elderly drivers is presented, including its most striking results. The project is funded by the Federal Ministry of Transport, Building and Urban Development (BMVBS) and aims to answer the question if active vehicle safety systems are able to support elderly people in staying mobile. Additionally, a list of criteria for designing active vehicle safety systems in the future and recommended procedures for political decisions was developed retrospectively. Therefore an extensive market research was carried out in the beginning of the project, containing a literature research, a survey with 70 elderly people and expert interviews. During the second phase test drives combined with the answering of standardized questionnaires and special workload assessments were carried out.
Composing controllers designed individually for interacting subsystems, while preserving the guarantees that each controller provides for each subsystem, is a challenging task. Motivated by this challenge, we consider in this paper the problem of synthesizing safety controllers for linear parameter-varying subsystems, where the system matrices of each subsystem depend (possibly nonlinearly) on the states of the other subsystems. In particular, we propose a method for synthesis of controlled invariant sets and associated controllers, that is robust against affine parametric uncertainties in the system matrices. Then we show for certain classes of parameter dependencies how to quantify the uncertainty imposed on the other subsystems by convexifying, with an affine map, the effects of these parameters. An analysis of this quantification is provided. In the second part of the paper, we focus on an application of this method to vehicle safety systems. We demonstrate how controllers for lane-keeping and adaptive cruise control can be synthesized in a compositional way using the proposed method. Our simulations illustrate how these controllers keep their individual safety guarantees when implemented simultaneously, as the theory suggests.
Cooperative vehicle safety systems (CVSSs) rely on vehicular ad-hoc networks (VANETs) for the delivery of critical vehicle tracking information. The wireless channel in such systems is shared by vehicles within the transmission range of each other. Due to the near-linear spatial distribution of vehicles in a highway scenario, the vehicular broadcast network is heavily affected by the hidden node interference phenomenon, which considerably limits its capacity. The performance of vehicle tracking application that is the basis for CVSS is therefore significantly affected by the performance of the underlying network. The two main parameters that affect the network condition and performance are the range and rate (frequency) of transmission of safety and tracking messages. In this paper, we analyze the effect of different choices of rate and range and present models that quantify network performance in terms of its ability to disseminate tracking information. Following a thorough analysis of the hidden node affected VANET, we show that channel occupancy or busy ratio can be used as a feedback measure that quantifies the success of information dissemination and, consequently, the CVSS, under different network conditions. These findings are used to design feedback control schemes for transmission range adaptation, which are robust to variations of road and network traffic.
Proactive vehicle safety systems based on vehicle-to-vehicle and infrastructure-to-vehicle communication are promising new approaches to reducing the number of accidents on our roads. In-vehicle applications are envisaged to provide a variety of services to the driver including warning about potential collisions and other hazardous situations. For the safe operation of these applications it is important not only to efficiently model the environment but also to reason about, and predict, how reliable such a model is under various circumstances. In this paper we propose an approach to estimating the reliability and availability of the wireless medium at hazardous locations by cooperatively detecting communication disturbances in order to allow for more accurate decisions by in-vehicle applications.
Vehicular ad hoc networks (Vanets) play a critical role in enabling essential emergency safety applications (e.g., Forward Collision Warning) and subsequently help the driver deal with emergency situations, These emergency applications have strict different QoS requirements mainly on latency time . In this work, we propose a Power Control Scheme, called PCS that adjusts the transmission power level to guarantee short delays for safety messages over 802.11p/DSRC, especially for occasional emergency messages. PCS aims to minimize contention within two-hop neighborhood of a vehicle under high- offered load conditions. Numerical results show the effectiveness of PCS scheme when coupled with either the traditional random access mechanism  or the priority-aware deterministic access protocol based on 802.11p/DSRC .
This paper presents a probabilistic and holistic prediction algorithm for vehicle states using multisensor fushion. Three concerns are mainly considered in this paper, i.e, reliable and reasonable information fusion, extension of predicted states, and real-time evaluation of prediction uncertainties. The main idea of this paper is that a state-prediction problem can be solved as a multistage optimal estimation problem based on the current vehicle motion, a road geometry description in the current body-fixed frame, a path-following behavior model, and the error covariance of each. The prediction algorithm consists of two sequential parts. The first part is estimation, which contains a vehicle filter that estimates the current vehicle states, and a road geometry filter, which approximates the road geometry. The second part is prediction, which consists of a path-following model that generates the future desired yaw rate, which acts as a virtual measurement, and a vehicle predictor, which predicts the future vehicle states by a maximum-likelihood filtering method. The prediction performance of the proposed method has been investigated via vehicle tests. Moreover, its applicability to integrated vehicle safety system (IVSS) has been validated via computer simulation studies. It is shown that the state-prediction performance can be significantly enhanced by the proposed prediction algorithm compared with conventional methods. The enhancement of the prediction performance allows for the improvement of driver assistance functions of an IVSS by providing accurate predictions about the future driving environment.
