AutoBox/Tandem-AutoBox

Housing for in-vehicle use

With AutoBox, dSPACE PHS hardware can be used for in-vehicle applications. It provides extended robustness and can be directly powered by a car battery.

  • Robust housing with space for 7 or 15 dSPACE PHS boards
  • Power supply for 12 V, 24 V, and 48 V electrical systems
  • Improved cold start behavior

Application Areas

AutoBox is the ideal enclosure for using your dSPACE PHS-based real-time system to carry out in-vehicle control experiments such as test drives in the development of powertrains, chassis control or advanced driver assistance systems. You can install AutoBox quite easily in your test car, e.g., in the trunk or the passenger cabin.

Key Benefits

AutoBox is a robust box for mounting processor boards and I/O boards. It provides space for dSPACE PHS hardware (7 slots in the AutoBox, 15 slots in the Tandem-AutoBox). Designed for in-vehicle use, AutoBox can operate with 12 V, 24 V and 48 V power supplies under rough environmental conditions.
