MicroAutoBox II

Compact and robust prototyping system for in-vehicle applications

MicroAutoBox II is a real-time system for performing fast function prototyping. It can operate without user intervention, just like an ECU.

  • More FPGA Performance for MicroAutoBox II

    In Release 2015-A, dSPACE adds an integrated FPGA board to round off its portfolio for the prototyping hardware, MicroAutoBox II, with new variants. The new variants, 1401/1511/1514 and 1401/1513/1514, are freely programmable and have a very powerful Xilinx® Kintex®-7 FPGA board (XC7K325T) that can solve even the toughest prototyping tasks.

  • Support for CAN FD

    The dSPACE DS4342 CAN FD Interface Module (FD = flexible data rate) can be used to extend MicroAutoBox II variants with IP module slots. The DS4342 provides two independent CAN channels, each of which can be used for CAN FD or CAN. Network management functions such as wake-up and sleep are also included.

  • Fast Double-Pack: Embedded PC with i7

     The Embedded PC extension for the compact prototyping system dSPACE MicroAutoBox II is now available in a new, more powerful variant with an Intel Core i7 processor. While the real-time component of a control system under development is calculated on the real-time processor of the MicroAutoBox II, the non-real-time component is processed on the Embedded PC equipped with the i7. MicroAutoBox II with Embedded PC is a combined system that is robust, compact and designed for in-vehicle use.

  • Completely Electric Supercar

    The Rimac Automobili Concept_One was designed from the ground up to be a fully electric supercar – the first of its kind. Not impressed? How does 1088 hp and 4 independent electric motors sound? All this power is kept in check by a MicroAutoBox.

  • No Driver Required

    Thanks to advances in the development of intelligent drive technology, the time is coming closer when self-driving vehicles will be a part of everyday road traffic. With the help of dSPACE MicroAutoBox, a group of researchers at the School of Automotive Studies, Tongji University, China, developed an electric prototype vehicle that can already drive by itself on the university campus.

Application Areas

MicroAutoBox can be used for many different rapid control prototyping (RCP) applications such as:
  • Powertrain
  • Chassis control
  • Body control
  • Advanced driver assistance systems (ADAS)
  • Electric drives control
  • X-by-wire applications
  • Aerospace applications

Key Benefits

The special strength of the MicroAutoBox hardware is its unique combination of high performance, comprehensive auto­motive I/O, and an extremely compact and robust design (extreme shock and vibration tests according to ISO 16750-3:2007) – all for a favorable price. This lets you equip several vehicles or a whole test fleet to check the reliability of your control functions. With dSPACE's combination of comprehensive software and hardware support, you can also keep overall system costs low. In addition to the standard I/O, MicroAutoBox offers variants with FPGA functionality for application-specific I/O extensions and for user-programmable FPGA applications. Moreover, there are MicroAutoBox variants with inter­faces for all major auto­motive bus systems: CAN, CAN FD, LIN, K/L-Line, FlexRay, and Ethernet. As an option, an additional Embedded PC can be integrated into the MicroAutoBox II.

More Features

MicroAutoBox can start up autonomously after power-up, with ECU-like boot-up times. A PC or notebook can be easily connected (hot-plugged) for application download, model parameterization, and data analysis via Ethernet. Application programs are stored in nonvolatile memory. MicroAutoBox contains signal conditioning for automotive signal levels and an integrated flight recorder for long-term data acquisition (incl. support of USB mass storage devices).


Five Standard Variants
MicroAutoBox is available in five standard variants, each with different interfaces and I/O functionalities. An ideal extension for the MicroAutoBox is the RapidPro hardware with its off-the-shelf signal conditioning and power stage modules. All standard variants can integrate an additional Embedded PC.
