Two new ADAS/AD simulating and validating technologies

dSPACE is making life easier for engineers working on advanced driver assistance systems (ADAS) and autonomous driving (AD) with two brand-new product releases: SIMPHERA and AURELION.

SIMPHERA is a web-based, cloud-ready solution for the simulation and validation of ADAS and autonomous driving functions. It speeds up the development process by enabling hundreds of test cases to run simultaneously at the click of a button. This is done with a virtual vehicle in a virtual environment using process automation. Engineers can generate endless reproducible test drives. Traffic scenarios can be freely defined or imported into the system, and corner cases can be easily replicated for broad test coverage. By simply changing parameters, new test-case variants can be quickly added for increased test depth.

While most ADAS/AD test cases are initially performed in a software-in-the-loop (SIL) simulation environment, SIMPHERA gives engineers the freedom to incorporate the actual hardware. This means that electronic control units can be tested under real-time conditions with a hardware-in-the-loop (HIL) platform as well. Engineers can access the same test suites that were used in the SIL stage and reuse them in the HIL simulation environment for an all-around efficient and reliable validation process.

Another useful feature of SIMPHERA is that it was designed with worldwide collaboration in mind. Its cloud-ready capability makes it accessible to anyone anywhere in the world, supporting distributed teams for true collaboration.

AURELION is dSPACE’s new solution for sensor-realistic simulation. It allows engineers to integrate high-resolution visualization, including realistic lighting and weather effects, to develop and validate perception sensors (camera, radar, lidar) used in ADAS/AD applications.

AURELION enables precise sensor environment simulation with its powerful 3D rendering engine, dSPACE simulation models and realistic 3D assets such as vehicles, pedestrians, buildings and roads. This solution comes with physical sensor models for lidar, radar and camera for accurate simulation of real-world effects.

The lidar sensor model simulates the generation of a point cloud while taking into account the environment and sensor effects. It detects multiple reflections per ray, as well as motion distortion effects, and supports dynamic scanning patterns. The radar sensor model calculates radar data with GPU acceleration in real time. Reflection and scattering are taken into account in the simulation, and adaptive ray launching ensures that all tiny objects are hit. This is a great benefit for scenarios with narrow objects such as streetlights, reflector posts and traffic signs. Finally, the camera sensor model provides high-fidelity graphics and lighting effects to create a realistic lens profile. Images can be modified with lens distortion, effects of the aperture, exposure time, color filter array and motion blur, etc.

SIMPHERA and AURELION provide engineers with a powerful, highly realistic test environment for simulating and validating ADAS/AD driving functions.
