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.

  • 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.

  • New DS1513 I/O Board

    The new DS1513 I/O Board for MicroAutoBox II increases the number of CAN channels to 6, and analog I/O to 32 ADCs and 8 DACs. These I/O interfaces can be easily configured via a user-intuitive dSPACE Real-Time Interface (RTI) blockset in the Simulink® environment. The CAN messages and communication strategy can be programmed using the RTI CAN or RTI CAN MultiMessage Blockset.

  • 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.

  • Sensor-Based Landing Aid

    ESG is developing a sensor-based landing aid (SeLa) that uses dust-penetrating radar to display the helicopter's position over the ground and enables the pilot to land safely, even in poor visibility. Once initial tests are completed successfully, the pilot is given a feel for the algorithms by running them on a MicroAutoBox in a flight simulator so that functions can be checked and optimized.

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 II 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 II offers variants with FPGA functionality for application-specific I/O extensions and for user-programmable FPGA applications. Moreover, there are MicroAutoBox II variants with interfaces for all major automotive bus systems: CAN, CAN FD, LIN, K-Line/L-Line, FlexRay, and Ethernet. As an option, an additional embedded PC can be integrated into the MicroAutoBox II. 

More Features

MicroAutoBox II can start autonomously after power-up, with ECU-like boot times. A PC or notebook can be easily connected (hot-plugged) for application download, model parameterization, and data analysis via Ethernet. MicroAutoBox II contains signal conditioning for automotive signal levels and an integrated flight recorder for long-term data acquisition (incl. support of USB mass storage devices). To improve safety aspects, MicroAutoBox II provides a two-stage watchdog concept for setting up task-specific surveillance and activating a pre-defined system behavior in critical states.

Eight Standard Variants
MicroAutoBox II is available in eight standard variants, each with different interfaces and I/O functionalities. All of these standard variants can integrate an embedded PC to use additional Windows- or Linux-based applications. For application-specific signal conditioning and power stages, the compact and modular RapidPro hardware is an ideal extension. With its off-the-shelf signal conditioning and power stage modules, it is possible to connect many different, user-specific sensors and actuators to MicroAutoBox II.
