Traffic Scenarios for Automated Vehicle Testing: A Review of Description Languages and Systems

Testing and validation of the functionalities and safety of automated vehicles shifted from a distance-based to a scenario-based method in the past decade. A number of domain-specific languages and systems were developed to support scenario-based testing. The aim of this paper is to review and compare the features and characteristics of the major scenario description languages and systems (SDLS). Each of them is designed for different purposes and with different goals; therefore, they have their strengths and weaknesses. Their characteristics are highlighted with an example nontrivial traffic scenario that we designed. We also discuss some directions for further development and research of these SDLS.

Modelling the ZalaZONE Proving Ground: a benchmark of State-of-the-art Automotive Simulators PreScan, IPG CarMaker, and VTD Vires

In our days, simulation based development is a core element of vehicle engineering, especially considering highly automated or fully autonomous vehicles. Accordingly, the paper presents a benchmark of three different automotive simulators: PreScan, IPG CarMaker, and VTD Vires. The three software tools were applied for the same goal, namely, modelling the ZalaZONE Proving Ground of Hungary for vehicle testing. The paper aims to highlight the experiences while creating the virtual models by presenting and comparing the relevant software features and providing suggestions for scientific or practical application.

Driving and Flying Simulators: A Review on Relevant Considerations and Trends

Flying and driving simulation has encouraged an enormous and growing community in a wide variety of areas such as research centers, driver or pilot training academies, vehicle-testing facilities, amusement parks, and even at home by household enthusiasts, providing carefully integrated visual and perceptual illusions of driving or flying real vehicles. The global research on this subject is explored during the period 2000 to 2019 from an interdisciplinary perspective based on a systematic methodology, providing both new and experienced researchers with broad guidance toward key aspects for further investigations and developments. Emphasis is given to the analysis of the findings and in particular to their applicability, to an extent not attempted earlier, by considering both human and machine aspects.

Development of a Scaled Vehicle Model for Dynamics Testing

The interest in using scaled models for dynamics testing of prototype vehicles is growing due to the high demand for autonomous driving. In the early design phases, vehicle testing is done using computer simulations. Even though computer simulations are proven to be extremely helpful in designing prototypes, simulation models need to be validated using realworld testing. There are high costs involved in vehicle testing and it’s dangerous to conduct aggressive driving manoeuvres with real drivers. As a solution, researchers have used scaled models. To validate the computer simulations, researchers matched the scaled model test data with full-size vehicle prototypes considering the dynamic similitude. However, previous work was limited to the analysis of the steady-state behaviour of vehicles. To accurately predict the behaviour, the transientstate response must be tested as well. Therefore, this paper outlines the precursory work of a scaled model with the ability to test both states during vehicle manoeuvres. This paper is structured as follows. Section II presents related work. Section III elaborates on the mathematical modelling and present the results of the computer simulations. Section IV presents the scaled model which will be developed. Section V concludes the findings, and present the future work of research.

Implementation of the KIR E-Test Program in the Technical Implementation Unit of the Motor Vehicle Testing Service of the Garut Regency Transportation Service

Implementing the KIR e-test program at the UPTD of the Garut Regency Transportation Service has been carried out since October 1, 2019. The KIR e-test program is a service innovation by changing the manual KIR test system using an IT-based system so that the KIR e-test application can simplify and shorten the service time for people who will do the KIR test. This study uses a qualitative method with descriptive analysis. The data collection techniques used include observation, interviews, and documentation. The data analysis technique used is data reduction, data presentation and conclusion drawing. From the results of the study, it was concluded that the implementation of the KIR e-test program had been implemented but encountered several obstacles, including information on changes in testing procedures from manual to electronic has not been informed to the public, so there are still people who think that the testing procedures carried out take a long time, so that vehicle owners prefer to use the services of brokers in testing the UPTD PKB Dishub Garut still lacks testers, especially testers who are certified and do not have a backup of e-KIR infrastructure. Implementing the KIR e-test is still prone to illegal levies because there are still brokers who call themselves service bureaus in collaboration with unscrupulous officers.

Study on Overturn Proof Monitoring System of Mobile Crane

While up-right build structures are under construction, an over-hung crane has a major role in efficient lifting and transporting heavy materials from one point to another. There are several types of cranes for a variety of construction sites, such as bridge/overhead, barge lift, tower crane, etc. The mobile crane is one of the most widely used types of construction equipment due to its mobility. Unfortunately, the number of crane accidents including casualties and deaths has increased over the last decade. In order to reduce these fatal tragedies, a dynamic simulator of mobile cranes based on analyzed overturn limit data has been developed and analysis results have been applied to site tests. The test bench is formulated to simulate the actual construction field and some practical experiments have been performed in realistic manners of operation. Moreover, wireless network communication systems are applied for monitoring the status of the crane from a distance where visibility is not secure. Consequently, the applicability in the field derived from operating the simulator and actual vehicle testing confirmed the feasibility of applying it to construction sites.
