车辆动力学建模和控制系统Siemens Simcenter PreSCAN 2021.1.0 x64 2021-07-15

PreScan 是一个模拟平台，包括一个基于 GUI 的预处理器来定义场景和一个运行时环境来执行它们。工程师用于制作和测试算法的主要接口包括 MATLAB 和 Simulink。PreScan 可用于从基于模型的控制器设计 (MIL) 到软件在环 (SIL) 和硬件在环 (HIL) 系统的实时测试。PreScan 可以在开环和闭环以及离线和在线模式下运行。它是一个开放的软件平台，具有灵活的接口，可以链接到第 3 方车辆动力学模型（例如 CarSIM、dSPACE ASM 等）和第 3 方 HIL 模拟器/硬件（例如 ETAS、dSPACE、Vector）。

PreScan 包含多个模块，共同提供 ADAS 系统开发人员所需的一切。直观的图形用户界面 (GUI) 可让您构建场景并对传感器进行建模，而 Matlab/Simulink 界面可让您添加控制系统。该接口还可用于导入现有的 Matlab/Simulink 模型，例如车辆动力学模型。运行您的实验时，可视化查看器提供场景的逼真 3D 表示。可选地，dSPACE Con​​trolDesk 和 NI LabVIEW 等工具可用于“数据采集”和“测试自动化”等活动。

该程序使用四个简单的步骤进行工作：
构建场景
专用的预处理器 (GUI) 允许用户使用路段、基础设施组件（树木、建筑物、交通标志）、参与者（汽车、卡车、自行车和行人）、天气条件（例如雨、雪和雾）和光源（例如太阳、前灯和灯柱）。通过读取来自 OpenStreetMap、Google Earth、Google 3D Warehouse 和/或 GPS 导航设备的信息，可以快速表示真实道路。

传感器建模
车辆模型可以配备不同类型的传感器，包括雷达、激光、摄像头、超声波、红外线、GPS 和用于车对 X (V2X) 通信的天线。传感器类型和传感器特性的轻松交换和修改有助于传感器设计和基准测试。

添加控制系统
Matlab/Simulink 接口使用户能够设计和验证用于数据处理、传感器融合、决策制定和控制以及现有 Simulink 模型（例如来自 CarSim、Dyna4 或 ASM 的车辆动力学模型）的重用算法。

运行实验
3D 可视化查看器允许用户分析实验结果。它提供了多个视点、直观的导航控件以及图片和电影生成功能。此外，与 ControlDesk 和 LabView 的接口可用于自动运行一批场景实验以及运行硬件在环 (HIL) 模拟。

PreScan is a simulation platform consisting of a GUI-based preprocessor to define scenarios and a run-time environment to execute them. The engineer’s prime interface for making and testing algorithms includes MATLAB and Simulink. PreScan can be used from model-based controller design (MIL) to real-time tests with software-in-the-loop (SIL) and hardware-in-the-loop (HIL) systems. PreScan can operate in open-loop & closed-loop, and offline & online mode. It is an open software platform which has flexible interfaces to link to 3rd party vehicle dynamics model (e.g. CarSIM, dSPACE ASM, etc) and 3rd party HIL simulators/hardware (e.g. ETAS, dSPACE, Vector).

PreScan comprises several modules that together provide everything an ADAS system developer needs. An intuitive graphical user interface (GUI) allows you to build your scenario and model your sensors, while the Matlab/Simulink interface enables you to add a control system. This interface can also be used to import existing Matlab/Simulink models such as vehicle dynamics models. When running your experiment, the visualisation viewer gives a realistic 3D representation of the scenario. Optionally, tools such as dSPACE ControlDesk and NI LabVIEW can be used for activities such as ‘data acquisition’ and ‘test automation’.

The program works using four easy steps:
Build scenario
A dedicated pre-processor (GUI) allows users to build and modify traffic scenarios within minutes using a database of road sections, infrastructure components (trees, buildings, traffic signs), actors (cars, trucks, bikes and pedestrians), weather conditions (such as rain, snow and fog) and light sources (such as the sun, headlights and lampposts). Representations of real roads can be quickly made by reading in information from OpenStreetMap, Google Earth, Google 3D Warehouse and/or a GPS navigation device.

Model sensors
Vehicle models can be equipped with different sensor types, including radar, laser, camera, ultrasone, infrared, GPS and antennas for vehicle-to-X (V2X) communication. Sensor design and benchmarking is facilitated by easy exchange and modification of sensor type and sensor characteristics.

Add control system
A Matlab/Simulink interface enables users to design and verify algorithms for data processing, sensor fusion, decision making and control as well as the re-use of existing Simulink models such as vehicle dynamics models from CarSim, Dyna4 or ASM.

Run experiment
A 3D visualisation viewer allows users to analyse the results of the experiment. It provides multiple viewpoints, intuitive navigation controls, and picture and movie generation capabilities. Also, interfaces with ControlDesk and LabView can be used to automatically run an experiment batch of scenarios as well as to run hardware-in-the-loop (HIL) simulations.
