Software validates vehicle environment sensors in virtual test drives

Aurelion, the new simulation software from dSpace can be operated either in the cloud or locally at the users’ premises. It generates photorealistic images in real time for camera simulation and, by means of ray tracing, an exact environment for radar and lidar simulation. Developers use Aurelion to simulate algorithms for autonomous driving during virtual test drives long before a prototype hits the road.

The software can be used across all phases of the development process – for example, for software-in-the-loop (SIL) tests, hardware-in-the-loop (HIL) tests or parallel validation in the cloud. The solution supports the development of artificial intelligence-based functionalities and training data, including training and testing neural networks.

A powerful 3D rendering engine, precise simulation models and realistic 3D assets such as pedestrians or vehicles enable the accurate simulation of sensors, environments, weather conditions, brightness conditions (day, night) and materials. Developers can thus simulate a wide range of scenarios and test corner cases that very rarely occur in real test drives in reality.

Aurelion draws on an extensive, continuously updated library of sensor models. This means that new sensors can be used in simulation solutions even before they come onto the market. To this end, the Paderborn-based tool manufacturer has entered into cooperation agreements with sensor manufacturers and is continuously expanding its collaboration with developers of camera, lidar and radar technology. There is also the possibility of integrating third-party sensor models.

 The new solution bundles functionalities of the dSpace applications MotionDesk and SensorSim in a single new product and also offers extended functionalities and more precision in the area of sensor simulation. In combination with other dSpace tools such as the ASM simulation models, the VEOS simulation platform and ModelDesk for parameterisation, dSpace offers an end-to-end solution for testing and validating the autonomous vehicle software stack.
