This work is divided into three parts: the first one presents two steering controllers using the sliding mode and the switched H∞ controllers, the second one describes an unknown input sliding mode observer, while the last one presents an approach to the diagnosis of critical driving situations. All existence conditions are established using the Lyapunov approach. Simulations are conducted to highlight the efficiency of the proposed approach using the experimental data recorded by an instrumented Peugeot 307 laboratory car. The diagnosis of the critical driving situations is achieved by the speed extrapolation concept using simultaneously a non–linear model, a steering control and road bank observer. The speed extrapolation concept is used in order to evaluate situations under high dynamic loads on a bend, using stability of the sideslip motion.","PeriodicalId":39322,"journal":{"name":"International Journal of Vehicle Autonomous Systems","volume":"12 1","pages":"334-366"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/IJVAS.2014.067868","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66821424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such systems aim to make the road driving potentially safer and more comfortable in the future. This research work motivates development of a hierarchical structure based on a MPC and vehicle dynamics control for path planning and collision avoidance scenarios up to the limits of vehicle handling. The proposed idea not only helps to overcome the main challenge concerned with real–time implementation of MPC, but also adds modularity to the structure, whereby the tasks of path planning and vehicle handling can be tackled independently. The control structure can easily be extended for collision avoidance and driver assistance functions with the human driver in the loop. Simulation results with ideal and high fidelity vehicle models indicate the effectiveness of MPC and show the effect of different parameters on the overall performance.","PeriodicalId":39322,"journal":{"name":"International Journal of Vehicle Autonomous Systems","volume":"12 1","pages":"307"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/IJVAS.2014.067867","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66821378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This threat assessment is based on estimation of the control margin afforded to a vehicle and is performed in a multi–threat framework. Given sensor information available about the surrounding environment, an algorithm first identifies corridors of travel through which the vehicle can safely navigate. The second stage then assesses the threat posed to the vehicle in each identified corridor via a metric associated with available control margin. For this purpose, the corridors are approximated by sets of trajectories generated from a lattice sampled in the vehicle's input space. The level of threat can then serve to influence autonomous navigation as an input to a decision–making layer. It also potentially allows a semi–autonomous control system to honour driver intent while ensuring safe and robust navigation in hazardous events. The benefit of such an approach is compared to common threat metrics in canonical scenarios. The method is also applied to the multi–lane road environment of highway navigation by post processing human driving data gathered from a simulator.","PeriodicalId":39322,"journal":{"name":"International Journal of Vehicle Autonomous Systems","volume":"12 1","pages":"384"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/IJVAS.2014.067869","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66821429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An understanding of human steering control behaviour is relevant to the design of autonomous and semi-autonomous vehicle controls. The driving task involved steering a linear vehicle along a randomly curving path. The theoretical steering controllers identified from the data were based on optimal linear preview control. A direct-identification method was used, and the steering controllers were identified so that the predicted steering angle matched as closely as possible the measured steering angle of the test subjects. It was found that identification of the driver’s time delay and noise is necessary to avoid bias in identification of the controller parameters. Most subjects’ steering behaviour was predicted well by a theoretical controller based on the lateral/yaw dynamics of the vehicle. There was some evidence that an inexperienced driver’s steering action was better represented by a controller based on a simpler model of the vehicle dynamics, perhaps reflecting incomplete learning by the driver.","PeriodicalId":39322,"journal":{"name":"International Journal of Vehicle Autonomous Systems","volume":"12 1","pages":"44"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/IJVAS.2014.057863","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66821055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To preserve consumers' trust in recent automotive electronics, the unsolved problem of system–level test, which goes far beyond testing lone components, should be remedied. In the future generation cars, several innovative applications could profit from the augmented bandwidth Ethernet can offer. In this paper, we present the design and implementation of innovative network analysis of the in–vehicle communication. Indeed, the system functions are accomplished on only one off–the–shelf and cost–effective computer (centralised processing), which permits online and offline analysis. Almost all current challenges, such as flexibility, performance (resource usage) and optimisation are taken into consideration. To validate the performance of our system, named 'CableFish', we perform several tests comparing it to other monitoring and analysis systems.","PeriodicalId":39322,"journal":{"name":"International Journal of Vehicle Autonomous Systems","volume":"12 1","pages":"367"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/IJVAS.2014.067860","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66821369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dynamic wheel-soil model can be used for wheels with or without grousers. Several case studies are presented to demonstrate the usefulness and applicability of this dynamic pressure-sinkage relationship. Hill climbing experiments were carried out using a smooth-wheel micro rover with a fixed suspension to confirm operational regions of the dynamic pressure-sinkage relationship. Single wheel testbed experiments were carried out to determine how well the model can predict changes in the number and length of the grousers on the wheel. It was concluded that dynamic pressure-sinkage relationship can predict the observed oscillations in the sinkage, drawbar pull and normal force with a single tuning case as the slip ratio and the configuration of the wheel changes.","PeriodicalId":39322,"journal":{"name":"International Journal of Vehicle Autonomous Systems","volume":"12 1","pages":"1"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/IJVAS.2014.057838","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66821465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, we propose a dynamic energy-efficient path planning algorithm that integrates mission prior knowledge with real-time sensory information to identify the most energy-efficient path for mission completion. Our proposed approach predicts and updates the distribution of the energy requirement for alternative paths using recursive Bayesian estimation through two stages: (a) exploration – road segments can be explored to reduce their energy prediction uncertainty; (b) exploitation – the most reliable path is selected using the collected information in the exploration stage and then traversed. Our simulation results show that the proposed approach outperforms offline methods, as well as a method that relies on exploitation only to identify the most energy-efficient path.","PeriodicalId":39322,"journal":{"name":"International Journal of Vehicle Autonomous Systems","volume":"12 1","pages":"221-246"},"PeriodicalIF":0.0,"publicationDate":"2013-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/IJVAS.2014.063021","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66821269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
