DS1554 Engine Control I/O Module
Universal I/O Module for Combustion Engine Control
The DS1554 Engine Control I/O Module upgrades the MicroAutoBox III DS1514 variants to a very powerful prototyping system for even the most complex tasks in advanced combustion engine control. The DS1554 therefore provides dedicated I/O interfaces, such as digital I/O channels for crank/cam processing and for generating injection/ignition pulses. Moreover, it is equipped with several analog I/O channels for detecting knocks and with channels for lambda processing. All these interfaces have a very low latency and are connected directly to the Kintex-7 FPGA of the MicroAutoBox III DS1514 FPGA Base Board in order to display the combustion process with a high resolution.
Addressed engine types:
- Combustion engines with up to 4 strokes (e.g. diesel, gasoline, hydrogen)
- Easy to install on MicroAutoBox III
- Digital I/O channels for crank/cam processing and generating injection/ignition pulses
- Analog I/O channels for knock detection and lambda processing
Application Areas
The DS1554 offers dedicated I/O interfaces with very low latency, high sampling rates and is connected directly to the Kintex-7 FPGA of the MicroAutoBox III DS1514 FPGA Base Board.
Advanced Combustion Engine Control with FPGA
In combination with the powerful Xilinx® Kintex®-7 FPGA (XC7K325T) of the MicroAutoBox-III-DS1514 variants, the DS1554 Engine Control I/O Module offers the highest possible performance and lowest possible I/O latency for even the most complex signal preprocessing tasks in advanced engine control. It provides lots of ready-to-use ConfigurationDesk functions for common engine control functions, such as crank and cam signal processing and the generation of ignition and injection pulses. The FPGA of the MicroAutoBox III can be used to process crank and cam signals with a resolution of 0.1° through its angle calculation unit. In addition, it can be used to process lambda data and evaluate knock signals to detect abnormal combustion conditions and ensure improved combustion stability.
The respective control functionalities in both the FPGA and the CPU of the MicroAutoBox III can be easily implemented using ConfigurationDesk and MATLAB/Simulink.
