Making use of these assets by integrating with their existing Is the process of imitation of the behavior of a modeled real-world system over time.Simulation infrastructure — whether off-the-shelf or internally-built— can often be a painful and time-consuming process.

Solution

The ASAM OpenDRIVE® A public specification, which has been developed by experts in a defined consensus-driven development process and was released by officials that represent a significant share of the industry for which it is targeted, giving the specification the necessary legitimacy to be called a 'Standard'.Standard acts like a digital blueprint for describing static elements of a road network. It allows engineers and developers to create a common language for defining these elements in simulations related to Autonomous Vehicles (AVs) and Advanced Driver-Assistance Systems (Advanced Driver-Assistance SystemsADAS). Road network definition, data exchange, common coordinate system and integration with other ASAM standards are all enabled by ASAM OpenDRIVE.

To provide a viable solution utilizing ASAM standards and to foster the development of safe autonomous vehicles, Ansys has partnered with BMW to conceptualize and deliver one of the most modern cloud-based Advanced Driver-Assistance SystemsADAS/AD Is the process of imitation of the behavior of a modeled real-world system over time.Simulation platforms i.e. Ansys AVxcelerate Autonomy™.

Additionally, to complement this scenario-based Is the process of imitation of the behavior of a modeled real-world system over time.Simulation platform, Ansys AVxcelerate Sensors™ offers a powerful suite of Physics-based sensors (Camera, LiDAR, Radar, Ultrasonic, Thermal Camera). These physics-based sensors can be used in combination with AVxcelerate Autonomy cloud-based platform.

   To help bring this comprehensive solution to market, Ansys AVxcelerate supports:

• a co-simulation model using the ASAM OSI Standard, offering a clean and well-understood interface to an ADAS/AD software stack or host simulator.
• the import and reuse of existing ASAM OpenDRIVE maps and ASAM OpenSCENARIO XML scenarios, which ensures that any existing customer content can be reused.
• ASAM OpenSCENARIO variations based on input parameters. 
• Environment simulator ensures the creation of ground-truth in ASAM OSI standards by consuming inputs in ASAM OpenSCENARIO and ASAM OpenDRIVE.
• ISO26262 certified toolchains. Soon, AVxcelerate Sensor will have native support for existing and future ASAM standards as well.

Further, Ansys offers another tool to ease this implementation - The Road Logic Suite toolkit for OpenDRIVE maps is an open source and easy-to-use tool that empowers developers to work effectively with OpenDRIVE maps. The Road Logic Suite tool offers functionalities for loading, validating, converting coordinates, and extracting valuable data from the road network descriptions. This is a reference open-source implementation of the ASAM OpenDRIVE A public specification, which has been developed by experts in a defined consensus-driven development process and was released by officials that represent a significant share of the industry for which it is targeted, giving the specification the necessary legitimacy to be called a 'Standard'.Standard. OSS reference implementation is key for safety critical The process of determining that a system performs and meets the needs for identified end users.Validation. Being open-source facilities regulatory authority inspections thereby increase trust in the solution.
