Environment Sensor Interface Unit

将数字数据输入摄像头、雷达和激光雷达ECU

自主驾驶系统使用多个环境传感器。在传感器融合和功能测试中仿真 HIL 传感器时,必须准确地同步仿真单个传感器。dSPACE Environment Sensor Interface Unit 支持依时性传送原始传感器数据至一个或多个摄像头 ECU。

  • Preconfigured ESI Units

    The Environment Sensor Interface Unit (ESI Unit) from dSPACE allows both real and simulated raw sensor data to be fed into ADAS/AD ECUs in a time-correlated manner. This is extremely useful for HIL tests of functions for autonomous driving, among other things. To make these tests as easy as possible, dSPACE now also offers preconfigured ESI Units for specific, widely used application scenarios:

    • ESI Kit YUV: Preconfigured Environment Sensor Inter¬face Unit for YUV camera simulation (GMSL2 or FPD-Link III)
    • ESI Kit DRIVE: Preconfigured Environment Sensor Inter¬face Unit for NVIDIA® DRIVE AGX

应用领域

对于环境传感器的开发和验证,例如雷达、摄像头和激光雷达,以及更普遍的ADAS/AD功能验证,支持一系列用于数据注入的ECU接口,这是至关重要的。除了基于OTA方法和目标列表的测试之外,注入原始数据或目标列表对于验证基于原始数据的感知和融合算法至关重要。Environment Sensor Interface(ESI)Unit支持所有相关的传感器接口,尤其适用于闭环和开环测试。先进的传感器仿真与ESI单元相结合,能够轻松在实际条件下提供低延迟的合成传感器数据。这对于在闭环和开环情况下验证硬件在环(HIL)仿真中的自动驾驶功能非常有用。如果使用RTMaps,记录的传感器数据可以轻松地进行重放。

主要优点

Environment Sensor Interface Unit支持为摄像头、雷达和激光雷达ECU的HIL测试以及自动驾驶的中央处理单元注入原始数据和目标列表。由于其灵活和可扩展的架构,ESI Unit支持通过万兆以太网进行激光雷达点云数据注入,通过MIPI CSI-2进行雷达原始数据注入,以及通过TI FPD Link III或Maxim GMSL进行摄像头原始数据注入。为了满足下一代ECU的要求,ESI Unit 可以进行配置,以仿真最新的传感器,包括基于FPGA的传感器模型。单个ESI Unit可同步仿真多达12个传感器,并支持超过50 Gbit/s的聚合带宽。结合多个ESI单元,您可以使用几十个不同的传感器测试自动驾驶的功能。借助强大的Xilinx® UltraScale+™ FPGA,特殊的客户需求和功能可以直接在ESI单元上实现。

预配置的Environment Sensor Interface Unit

由于NVIDIA® DRIVE PX2 和AGX平台被广泛应用于自动驾驶功能的预开发和研究,dS PACE为摄像头原始数据注入提供了一个预配置的ESI Unit。结合使用dSPACE AURELION (Sensor Simulation) 多达四个摄像头(Sekonix SF332x)可以仿真为现成的版本。
