Application Areas

The powerful system can be added to or replace an electronic control unit (ECU), and lets you experience and test control functionalities in a real environment. MicroAutoBox III is ideal for many different rapid control prototyping (RCP) applications from autonomous driving to zero emissions either as a single demonstrator or for equipping entire test fleets. Examples of application fields are:

E-mobility, electrification, and powertrain control
Assisted, highly automated, and autonomous driving
Chassis, body, and vehicle dynamics control
Supervisory and domain control
Bus/network gateway and monitoring
Noise, vibration, position, and motion control

Key Benefits

The MicroAutoBox III uniquely combines high performance, comprehensive automotive I/O including bus and network support, and an extremely compact and robust design – all for a favorable price. The comprehensive software environment lets you configure, program, and operate the system easily and with minimum effort.

Hardware Variants

The MicroAutoBox III is available in different variants, which provide different numbers of analog or digital I/O channels, advanced bus and network interfaces, or even a user-programable FPGA for very fast control loops as required in e-mobility applications. Furthermore, there are dedicated extensions, e.g., a MicroAutoBox III Embedded PC for ADAS/ AD applications or an I/O module for engine control. All this makes the MicroAutoBox III a powerful and flexible development system for nearly all mechatronic in-vehicle applications, from autonomous driving to zero emissions.

To ensure that the MicroAutoBox III can also be used in field tests when all processors are constantly working under full load, dSPACE offers a cooling unit. Active cooling extends the permissible temperature range so that the MicroAutoBox III also functions safely under extreme conditions.

The cooling unit can be easily integrated without changing the footprint of the MicroAutoBox III.

The MicroAutoBox III can also be combined with the new AUTERA hardware, offering a perfect system combination for data logging and prototyping applications in the field of autonomous driving.

The MicroAutoBox III contains a processor board (DS1403) and at least one I/O board. The processor board executes the real-time application and the I/O board provides the electrical interfaces for measuring and controlling signals of external devices and those for bus and network communication, such as CAN or Ethernet. Up to two boards can be added to the basic version.

The following I/O boards are available for the MicroAutoBox III:

I/O Board	Description
DS1511 I/O Board	A universal I/O board that provides more digital I/O channels.
DS1511B1 I/O Board	A universal I/O board that provides more digital I/O channels and an extended voltage range of the analog input channels from -10 to +10 V.
DS1513 I/O Board	A universal I/O board that provides more analog I/O channels and more CAN interfaces.
DS1514 FPGA Base Board	A board with an FPGA for application-specific I/O extensions and for user-programmable FPGA applications. To provide I/O interfaces, you have to install I/O modules on this board. You can also add or replace the I/O modules that are installed on the DS1514 FPGA Base Board.
DS1521 Bus Board	A bus and network board that offers more automotive bus interfaces, such as CAN FD and automotive Ethernet.

The following variants of MicroAutoBox III are available:
