MicroAutoBox Hardware

Compact, stand-alone prototyping unit

Key Features Develop, test, and optimize control functions rapidly and reliably in real time

Variants for a wide range of applications with CAN, LIN, K/L Line, and FlexRay interfaces

Robust and compact design ideal for in-vehicle prototyping

Integrated flight recorder for long-term data acquisition

Description Application AreasMicroAutoBox is a real-time system for perform-ing fast function prototyping from scratch. It operates without user intervention, just like an ECU. MicroAutoBox can be used for many different rapid control prototyping (RCP) applica-tions, for example: Chassis control Powertrains Body control X-by-wire applications

Key BenefitsThe special strength of the MicroAutoBox hardware is its unique combination of high- performance, comprehensive automotive I/O, and an extremely compact and robust design – all for a favorable price, which lets you equip several vehicles or a whole test fleet to check the reliability of your control functions. Moreover, with our comprehensive software and hardware support, you can also keep overall system costs low. MicroAutoBox offers interfaces for all major automotive bus systems: CAN, LIN, K/L Line, and FlexRay.

Three Standard VariantsMicroAutoBox is available in three standard variants which differ in terms of interfaces and I/O functionalities. With interfaces to the CAN bus, the LIN bus, to K/L Line (all three MicroAutoBox variants) and the FlexRay bus (MicroAutoBox 1401/1505/1507), intelligent sensors and ac-tuators can be integrated during the prototyping process, and safety-critical real-time systems can be developed. dSPACE offers engineering services to adapt the I/O and signal conditioning to your specifications.

More FeaturesApplication programs are stored in nonvolatile memory, allowing MicroAutoBox to start up autonomously after power-up. A PC or note-book can be connected temporarily for program download and data analysis (hot plugging). I/O functionalities for typical automotive applications are already included, and the box contains signal conditioning for automotive signal levels.

CertificationsStandardsLike all dSPACE hardware products, MicroAuto-Box meets the requirements of the European Committee for Electrotechnical Standardization (CENELEC) and is therefore CE-compliant: EN 61000-6-2: Immunity standard for

industrial environments EN 61000-6-4: Emission standard for

industrial environments

Use CaseBypass-Based PrototypingIn bypass-based prototyping, existing ECUs are optimized or partially revised to obtain a new control strategy. In this example, an automo-tive ECU is connected to MicroAutoBox via the ECU interface. The original ECU executes all the functions that will remain unchanged, while the new algorithms are calculated in MicroAutoBox. The results are then transmitted back to the

MicroAutoBox Hardware

Digital I/O Software Support for Drives Control Edge AlignedDrives control provides multi-channel PWM generation, which can be used to manage up to three half bridges for three-phase current motor control, for example. Drives Control Edge Aligned uses PWM signals that are synchronized to the rising edges of the signals. The incremental encoder interface can be used to decode the signals of an incremental encoder and to read data on the drive‘s speed and position.

Functionality Description

PWM generation/measurement 3 channels PWM edge aligned, 5 Hz … 50 kHz, duty cycle 0 … 100 %

4 PWM/frequency outputs, 0.625 Hz … 100 kHz, variable period, duty cycle 0 … 100%, up to 16-bit resolution

4 channels for frequency or pulse width measurement

Incremental encoder interface 3 channels incremental encoder digital inputs with index input

Digital I/O Software Support for Drives Control Center AlignedDrives Control Center Aligned allows dead times and inversion functions to be used. Dead times are used to reduce the effective PWM duty cycle slightly. This is useful if signals are required to control the low or high side of a half bridge.

Functionality Description

Customer-Specific MicroAutoBox

I/O SpecificationsdSPACE offers engineering services to adapt the I/O and signal conditioning of MicroAutoBox to your specifications. As regards I/O, dSPACE offers predeveloped, verified designs that can easily be integrated in MicroAutoBox. In general, these modules do not have to be modified to suit your application, which saves development time and reduces engineering costs. The same I/O modules can of course be integrated several times. dSPACE will also include the I/O circuit designs you provide, such as a company-specific CAN controllers, ASIC, or plug-on devices, and also design new circuits according to your speci-fications.

Signal ConditioningThe signal conditioning portion of MicroAuto-Box can also be adapted to your requirements. Engineering service is available for integrating filter circuits, amplifiers and high-current high-side/low-side drivers. Since the requirements regarding signal conditioning vary with custom-er’s needs, this segment is fully customer-specific. And if you want to include your own concepts, dSPACE will integrate your designs in the board layout. You can even completely design the segment yourself.For further signal conditioning options, please see our RapidPro hardware.
