通过虚拟试驾来模拟真实世界的性能,解决自动驾驶汽车(AV)和高级驾驶辅助系统(adas)的设计挑战.

autonomous Vehicles and adas

自动驾驶汽车(AV)和高级驾驶辅助系统(adas)带来了更高的复杂性,需要进行更多的测试. 在产品开发时间内探索所有需要的场景需要高级模拟和高性能计算(hpc)的应用. Altair技术使客户能够提供解决方案,使汽车和卡车在无人驾驶的道路上更加安全.

Altair simulation is vital to vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-everything (V2X), AV, and adas development at our customers. 在所有三种情况下,天线是创建无缝和可靠通信所需的关键. And Altair offers Solutions in a wide array of engineering for antennas, from design to placement) to communication. 天线设计的一些性能标准可以在物理天线室中测试, but despite the huge expense they do not represent a real-world environment. for this, 更多的开发团队正在使用Altair在虚拟城市中模拟设备信号强度和数据吞吐量.
