AutoBox/Tandem-AutoBox

Housing for in-vehicle use

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

Application Areas

AutoBox is the ideal enclosure for using your modular dSPACE real-time system for in-vehicle control experiments such as test drives in the development of powertrains, ABS or chassis control. You can install AutoBox quite easily in your test car, for example, 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 hardware (7 slots in the AutoBox, 14 slots in the Tandem-AutoBox). One of the strengths of AutoBox is that it can operate in various electrical systems such as 12 V, 24 V, and 48 V.

Remote control General
  • Overvoltage-protected remote on/off input. Overvoltage protection of the remote pin is also 100 V. If the remote pin is connected directly to the vehicle battery, AutoBox will always be on, and the vehicle battery will soon be exhausted if the engine is not running. A switch is therefore highly recommended.
  Input resistance at remote input
  • 44 kΩ tied to GND
  • 47 kΩ tied to GND
  Remote on voltage
  • > 4 V
  Remote off voltage
  • < 1 V
Shock and vibration test EN 60068-2-6

  • During this test, AutoBox continuously executed a program incl. I/O without any failures
  EN 60068-2-27
  • Mechanical test of shock resistance
  • Test conditions: shock, 3-axis test, 11 ms at 15 g
  • During this test, AutoBox continuously executed a program incl. I/O without any failures
Mounting positions
  • Horizontal position (with shock mounts below)
  • Vertical position
  • Not allowed: upside-down position
Grounding
  • Circuit ground is connected to the backplane ground, which is isolated from the vehicle battery ground
Physical size
  • 195 x 220 x 480 mm (7.7 x 8.6 x 18.9 in) incl. shock mounts
  • 195 x 400 x 495 mm (7.7 x 15.7 x 19.5 in) incl. shock mounts
Weight (without boards)

Ambient temperature4)
  • 0 ... 55 °C (32 ... 131 °F)
  • 0 ... 55 °C (32 ... 131 °F)

 

1) Maximum voltage between any input pins or any output pins and output ground must not exceed 100 V.
2) Cannot be reached in the standard AutoBox configuration (DS1005 or DS1007 with various I/O boards).
3) The sum of the output currents of the rails must not exceed the maximum output power. 4) The dSPACE processor and I/O boards have different maximum ambient temperatures. When they are installed together, the lowest maximum ambient temperature applies.
