Vehicle Control Unit VCU

The Vehicle Control Unit (VCU) is a highly powerful processing unit for customer-developed functions integrating a flexible logging device with high speed logging capability of up to 200 kHz.

The processing cores feature floating-point arithmetic and a high-end FPGA for ultimate performance and flexibility. The customer software development process is based on MATLAB/Simulink to significantly speed up algorithm development (automatic code and documentation generation).

It offers real time Ethernet functionality to exchange e.g. data used in control algorithms between devices (guaranteed latency time 1 ms).

This device comes with a basic software consisting of operating system, H/W-drivers and low-level functions like pin setup, diagnostics, etc. The customer can freely develop his own application software using the MATLAB/Simulink environment.

Features

  • 667 MHz Dual Core Processor exclusively for customer code execution (MATLAB based)
  • Identical, dedicated 667 MHz Dual Core Processor exclusively for logging purposes
  • High Speed Logging 200 kHz of 6 analogue inputs (optional)
  • Real time Ethernet SERCOS 3
  • Event logging, Configurable pre-event logging

Upgrade Real Time Ethernet

Enables the VCU to operate as a real time Ethernet master or slave. Guaranteed latency time of 1 ms. Ideal for time critical data transfer as needed in online control algorithms involving data from different devices.
Two interfaces allow for a ring topology (redundancy in case the RTE line experiences damage).
The VCU features a reasonable set of SERCOS3 instructions although not the full SERCOS3 standard is implemented. The ECU side can act as a SERCOS3 master; the logger side can act as a SERCOS3 slave.

Upgrade CCP Master

Enables CCP master functionality to request data from foreign devices via CAN/CCP protocol.
