DS4302 CAN Interface Board1)

CAN 总线接口

你可以通过DS4302 CAN Interface Board将dSPACE 系统连接至控制器区域网络 (CAN)。这个板卡提供四个独立的CAN通道,每个通道都有一个CAN控制器和三个不同的CAN 收发器。

The end of life for this product has been set. Please see the footnote for more detailed information.


DS4302 CAN Interface Board应在控制器局域网 (CAN) 环境下运行,主要应用于汽车和自动化行业。DS4302 的典型应用领域包括:

  • 车载快速控制原型
  • 硬件在环 (HIL)
  • 残余总线仿真
  • 自动化任务


DS4302 能使 dSPACE 系统加入 CAN 总线通信中,无需使用额外的电子接口元件。四个独立的通道上各有三个单独的收发器,可覆盖某些CAN应用领域。其中包含一个用于实时硬通信的高速收发器和一个用于执行舒适型电子元件等任务的容错低速收发器。DS4302 可以在 Simulink® 模块框图中完成所有配置,无需进行 CAN 控制器的编程。


使用 RTI CAN Blockset,您可以在 Simulink® 中采用对话式方法轻松配置所有 CAN 接口,无需任何复杂的 CAN 控制器编程。配置选项包括消息设置、中断配置、消息时戳等。如果已有通信描述文件,最简单的方式是直接导入这些文件,然后配置 CAN 硬件。为了在硬件在环 (HIL) 应用程序中高效、动态处理复杂 CAN 设置,我们提供了 RTI CAN MultiMessage Blockset,它允许您利用 Simulink® 模块管理大型 CAN 消息包(> 200 条消息)。

1)The end of life of the dSPACE PHS (peripheral high-speed) hardware for modular systems is planned for December 31, 2024. You can still buy the related products up to and including December 31, 2021. New Releases of dSPACE software will still support the dSPACE PHS hardware for modular systems until at least the end of 2023. After the end of life, no services of any kind will be available for these products. We advise against using the PHS hardware products in new projects. For new projects we recommend that you use SCALEXIO, the latest dSPACE technology for modular real-time systems.
