Usage of simulation techniques like Vehicle-in-the-Loop, Scenario-in-the-Loop, and other mixed-reality systems are becoming inevitable in autonomous vehicle development, particularly in testing and validation. These methods rely on using digital twins, realistic representations of real vehicles, and traffic in a carefully rebuilt virtual world. Recreating them precisely in a virtual ecosystem requires many parameters of real vehicles to follow their properties in a simulation. This is especially true for vehicle dynamics, where these parameters have high impact on the simulation results. The paper's objective is to provide a method that can help reverse engineering a real car's suspension characteristics with the help of a genetic algorithm. A detailed description of the method is presented, guiding the reader through the whole process, including the meta-heuristic function's settings and how it interfaces with IPG Carmaker. The paper also presents multiple measurements, which can be effortlessly recreated without expensive devices or the need to disassemble any vehicle parts. Measurements are reproduced in two separate simulation tools with special scenarios providing an efficient way to analyze and verify the results. The provided method creates vehicle suspension characteristics with adequate quality, opening up the possibility to use them in the creation of digital twins or creating virtual traffic with realistic vehicle dynamics for high-quality visualization. Results show satisfying accuracy when tested with OpenCRG.

VIRES 的 Virtual Test Drive 产品（VTD）为工程师提供了进行自动驾驶仿真所需的所有要素，同时，VTD不仅兼容 MSC 软件的内部技术，而且兼容许多第三方软件。

举例来说，VTD 不仅提供了两种不同的用来表征车辆动力学的嵌入式技术（具有不同的仿真速度和结果准确度），还能与 Adams Car（车辆动力学仿真的事实标准）或其他任何车辆动力学软件共同使用。VTD 的交通模型也毫不逊色：VTD 具备业内最全面的交通仿真能力（可根据多个参数来设置每辆车的驾驶风格，必要时可同时仿真数千辆车）；但也可以将其他交通模型整合到 VTD 中，例如 SUMO。

This volume contains the proceedings of the SUMO Conference 2017 which was held from 8th to 10th

May 2017 with a focus on autonomous mobility. In the current transition process traffic simulation is

the only tool which can give us insights in the mechanisms of traffic in largely automatized traffic

scenarios. SUMO as an open source tool provides a wide range of traffic planning and simulation

functionalities to support the scientific community. The conference proceedings offer an overview of

the applicability of the SUMO tool suite as well as its universal extensibility due to the availability of

the source code. The major topic of this fifth edition of the SUMO conference is the calibration of

simulation to real world or handbook data as well as communicating networks of intelligent vehicles.

A number of contributions cover heterogeneous traffic networks, junction control and new traffic

model extensions to the simulation. Subsequent specialized issues such as emission modelling and

personal rapid transit simulation are targeted as well. At the conference the international user

community exchanged their experiences in using SUMO. With this volume we provide an insight to

these experiences as inspiration for further projects with the SUMO suite.

This volume contains the proceedings of the SUMO2015 – Intermodal Simulation for

Intermodal Transport Data, which was held from 7th to 8th May 2015 in Berlin-Adlershof,

Germany. SUMO is a well established microscopic traffic simulation suite which has been

available since 2002 and provides a wide range of traffic planning and simulation tools. The

conference proceedings give a good overview of the applicability and usefulness of simulation

tools like SUMO ranging from new methods in traffic control and vehicular communication to

the simulation of complete cities. Another aspect of the tool suite, its universal extensibility

due to the availability of the source code, is reflected in contributions covering rapid scenario

prototyping and interfacing improvements to govern microscopic traffic simulation results.

The major topic of this third edition of the SUMO conference is the interaction of different

types of traffic and intermodality. Several articles cover heterogeneous traffic networks as well

as logistics and pedestrian extensions to the simulation. Subsequent specialized issues such as

disaster management aspects and applying agile development techniques to scenario building

are targeted as well. The conference’s aim was bringing together the large international user

community and exchanging experience in using SUMO, while presenting results or solutions

obtained using the software or modeling mobility with open data. Let you inspire to try your

next project with the SUMO suite. There are many new applications in your environment.
