Best of What’s New in Simcenter Prescan 2407

With Siemens' previous release of Simcenter Prescan, the company introduced a method to tackle the scalability and performance of hardware-in-the-loop (HiL) setups. With Simcenter Prescan 2407, Siemens is making functionality available for the Physics Based Camera.  

Next to solving the sensor data transfer scalability problem, the company is also creating a hardware-agnostic modular HiL framework that allows for the receiving of the control signal from the device under test and feeding it to a real-time platform running vehicle dynamics.

This release marks the introduction of this framework with a demonstrator that can be run by users. Unlike the previous HiL setups where a Simcenter Prescan installation on the real-time hardware system was required, this demo will not require this installation. It will deploy Simcenter Prescan on a simulation PC while only running the vehicle dynamics on a real-time system. 

Navigation on Autopilot

This release focuses on enabling users to handle navigation on autopilot use cases with Simcenter Prescan. An obstacle with navigation on autopilot system design and testing using simulation is to get accurate road and lane information from the simulator. In this release, Siemens has extended lane marker sensor to provide additional outputs that are required to enable navigation on autopilot use cases.

Enhanced Radar and Camera Simulation 

Modeling rough surfaces for radar simulation is complex because radar waves interact with these surfaces differently compared to point targets. Rough surfaces scatter radar waves in multiple directions. The Physics-based Radar accurately captures this material behavior, ensuring that the power return of specular reflections matches measurements and nonspecular reflections align well with existing data.

The company has also enhanced the fisheye camera model to realistically simulate raindrop movements over the lens, accounting for shape and image mask. 

Siemens has also expanded its library of ready-to-use 3D assets, including a 53-ft. trailer model and additional human models.

What’s Next? 

Simcenter Prescan, as part of the Simcenter Autonomy portfolio, offers a solution to transform drive data into scenario snippets ready for closed-loop testing and safety validation, the company reports.
