Suitable and representative test scenarios need to be investigated, since it is impossible to completely test the multitude of potential radio environments, and real drive tests are very expensive, time consuming, and hardly reproducible. This paper proposes a basic two-path propagation model as a basis for performance testing because of its relevance in wireless communications and the potential to adjust worst-case transmission conditions. The model has been successfully implemented in our multi-purpose test facility. The implementation has been verified by interference measurements in the signal domain at RF level. Measured values compare favourably with expectation. Application oriented verification has been achieved by creating a functional LTE link in our shielded anechoic chamber and has been used to conduct end-to-end data throughput tests. The measured data throughput follows the expected interference pattern.","PeriodicalId":384049,"journal":{"name":"2019 IEEE International Conference on Connected Vehicles and Expo (ICCVE)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128433616","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}

However, modern traffic signal controllers allocate green time using vehicle sensors and therefore the anticipated green time has significant stochastic variation. This study develops a methodology to characterize green time stochastic variation for actuated-coordinated operation. During the peak hours where the demand was highly consistent, green intervals can be predicted with high certainty. In contrast, during midday and late evening, stochastic variation increased significantly due to the varying arrival patterns and associated real-time responsiveness of the traffic signal controller. The statistical characterization methods presented in this paper are important for green light optimized speed advisory (GLOSA) and eco-driving, technologies that rely on having an accurate estimate of the beginning of green (BOG) and end of green (EOG). Prior knowledge on typical values of how early to stop or shutdown the vehicles at a traffic signal approach can significantly improve efficiency and manage emissions for CAV. The paper concludes with a proposed graphical performance measure chart that can be used by traffic engineers and automotive vendors to frame the discussion on traffic signal operation.","PeriodicalId":384049,"journal":{"name":"2019 IEEE International Conference on Connected Vehicles and Expo (ICCVE)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132533443","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}

Compliance with these norms requires several steps during the safety life-cycle. A system definition is followed by the allocation of functional objectives to architectural elements. The safety analysis then includes the identification of safety goals and respective Automotive Safety Integrity Level (ASIL - injury risk) assessments as required by the desired automation level. Finally, safety mechanisms are included to provide necessary fault coverage and ensure that safe modes and states are reached in the presence of system faults. The focus of this paper is to provide a methodical definition process of a hypothetical AV domain controller architecture. Our proposed process includes an assortment of typical functional objectives and attributes consistent with the Operational Design Domain (ODD) at automation levels 3, 4 and 5. The intent of this paper will be to ensure that the safety goals and requirements are completely and correctly stated at the start of the development process and then propagated accurately to the final design and implementation with-out omission.","PeriodicalId":384049,"journal":{"name":"2019 IEEE International Conference on Connected Vehicles and Expo (ICCVE)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133038046","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 adaptations are usually required due to the fact that sensors and actuators have a number of imperfections such as delays, offsets and inherent noise processes. Here, such a problem in relation to the development of a lane keeping control algorithm is presented. An in-house developed lane keeping controller based on a high-fidelity simulation environment was planned to be transferred to a real demonstrator test vehicle. First tests showed significantly deteriorated and unstable performance results of the corresponding controller, which was due to sensor delays and actuator imperfections. After the diagnosis of the problem, an approach to mitigate these issues was undertaken by predicting the delayed sensor data utilizing a linear Kalman filter and an a-priori predictor. The Kalman filter and a-priori predictor design approach is based on a discrete-time version of the lane tracking model. The approach and the corresponding results were demonstrated using simulation and real vehicle implementation results that were evaluated in real driving conditions.","PeriodicalId":384049,"journal":{"name":"2019 IEEE International Conference on Connected Vehicles and Expo (ICCVE)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116125010","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 places an extreme burden not only on original equipment manufacturers (OEMs) of connected and autonomous vehicles (CAVs), but also on Tier 1 suppliers of CAV components, both in terms of cost and delivery time. To this end, multiple simulation platforms and techniques have emerged, such as hardware-in-the-loop testing methods, while the concept of co-simulation is gaining popularity as a more comprehensive solution for testing and validating CAVs. The aim of the DigiCAV project is to explore the feasibility of a co-simulation platform adopting a test-driven development approach for CAVs, by enabling a seamless testing and validation process across all stages of development, supporting a wide range of testing from model-in-the-loop of a CAV component all the way to vehicle-in-the-loop of a fully assembled vehicle on HORIBA MIRA's dedicated CAV proving ground test facilities. Furthermore, emphasis will be put on quality aspects such as testing accuracy, usability and protection of intellectual property rights. This paper introduces the DigiCAV project and disseminates results from its first deliverable focusing on capturing user requirements for the proposed simulation platform.","PeriodicalId":384049,"journal":{"name":"2019 IEEE International Conference on Connected Vehicles and Expo (ICCVE)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123709993","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}
