Download or read book Autonomous Real Time Testing written by Thomas Michael Fehlmann and published by Logos Verlag Berlin GmbH. This book was released on 2020-01-17 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Software testing is becoming increasingly important because more and more products are software-intensive. Cars, for example, contain more and more control software (ECUs) that are networked with each other. With new rail vehicles, software problems delay commissioning by months, even years, because the different components are not coordinated with each other. A timely system test would help, but there is a lack of time and resources. The functionality of the software is simply too great. So, you must automate. Automation is not only necessary for the execution of tests, but above all for the generation of suitable test cases. This is possible with Combinatory Logic, the Analytic Hierarchy Process (AHP), and Quality Function Deployment (QFD). When today’s cars use map services from the cloud, or their own sensors, for an Advanced Driving Assistance System (ADAS) to perform driving decisions; or when in the future an autonomous car meets another; or with truck platooning; or when adding a new, previously unknown device to an IoT orchestra, the original base system expands its functionality. Therefore, such an expanding system needs being retested before it can do decisions with the potential of affecting harm to humans or things, after each update, after each learning. This is Continuous Testing during operation; it supplements Continuous Delivery and Continuous Integration. Disruptive innovations in automotive require an equally disruptive new approach to testing of software-intense systems. This requires moving from once-upon-a-time testing before release to autonomous real-time software & systems testing during operations, with indications to users and suppliers about the actual state and testing results. This book explains the theory and the implementation approach for a framework for Autonomous Real-time Testing (ART) of a software-intense system while in operation.

Download or read book Development of a Test Bed for Real time Guidance and Control of an Autonomous Vehicle written by Nicholas H. Lin and published by . This book was released on 2006 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: An operational prototype of a ground vehicle that may be used as a test bed for future experiments in autonomous guidance, navigation, and control is developed. Key topics in the research include vehicle dynamics and modeling, inertial navigation, hardware/software integration, and system identification. The vehicle dynamics are derived from a simplified 3 degree-of-freedom (2 translational axes and 1 rotational axis) model, and inertial navigation equations are developed for the 2-dimensional, planar case. Descriptions of the hardware subsystems, which include the vehicle, onboard computer, sensors, actuators, and communications radio are presented. The execution of the real-time, onboard software used to perform control input/output as well as the ground station software application is outlined. Finally, the methodology and results of system identification experiments used to estimate the servo actuators and vehicle modeling parameters are given. Field testing demonstrated successful execution of the onboard and ground station software applications as well as the sensors and actuators subsystems. The vehicle was operated open-loop by uploading a sequence of steering and throttle commands from the ground station, and the sensor measurement data was recorded. The recorded data was used to estimate modeling parameters of the servo actuator mechanisms and the vehicle. The servo actuator models obtained from identification resulted in good matching between the simulated and physical responses with little deviation. The estimated vehicle parameters obtained from identification also resulted in good matching between the simulated and physical responses. Deviations between the simulated and physical responses are likely due to measurement errors present in the calculation of the vehicle states. The results of this research provide a proof-of-concept and demonstrate the viability of constructing an operational platform for vehicle autonomy.

Download or read book Robust Perception from Optical Sensors for Reactive Behaviors in Autonomous Robotic Vehicles written by Alexander Schaub and published by Springer. This book was released on 2017-07-18 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alexander Schaub examines how a reactive instinctive behavior, similar to instinctive reactions as incorporated by living beings, can be achieved for intelligent mobile robots to extend the classic reasoning approaches. He identifies possible applications for reactive approaches, as they enable a fast response time, increase robustness and have a high abstraction ability, even though reactive methods are not universally applicable. The chosen applications are obstacle avoidance and relative positioning – which can also be utilized for navigation – and a combination of both. The implementation of reactive instinctive behaviors for the identified tasks is then validated in simulation together with real world experiments.

Download or read book Autonomous Driving written by Markus Maurer and published by Springer. This book was released on 2016-05-21 with total page 698 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book takes a look at fully automated, autonomous vehicles and discusses many open questions: How can autonomous vehicles be integrated into the current transportation system with diverse users and human drivers? Where do automated vehicles fall under current legal frameworks? What risks are associated with automation and how will society respond to these risks? How will the marketplace react to automated vehicles and what changes may be necessary for companies? Experts from Germany and the United States define key societal, engineering, and mobility issues related to the automation of vehicles. They discuss the decisions programmers of automated vehicles must make to enable vehicles to perceive their environment, interact with other road users, and choose actions that may have ethical consequences. The authors further identify expectations and concerns that will form the basis for individual and societal acceptance of autonomous driving. While the safety benefits of such vehicles are tremendous, the authors demonstrate that these benefits will only be achieved if vehicles have an appropriate safety concept at the heart of their design. Realizing the potential of automated vehicles to reorganize traffic and transform mobility of people and goods requires similar care in the design of vehicles and networks. By covering all of these topics, the book aims to provide a current, comprehensive, and scientifically sound treatment of the emerging field of “autonomous driving".
