Vehicle Control Unit VCU MS 50.4P

The VCU MS 50.4P (Performance) is a highly powerful processing / logging unit for race applications.

Based on our broad base of platform function, we support you with customized VCU functions for a tailor-made solution.

In addition, you can quickly develop your individual customer software based on MATLAB/Simulink to significantly speed up algorithm development (automatic code and documentation generation, requires CCA package) – including extensive simulation capabilities.

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

Features

  • 866 MHz Dual Core Processor exclusively for vehicle control functionality (MATLAB based)
  • Identical, dedicated 866 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 High Speed Logging Package

6 ANA

0 to 5 V, 200 kHz logging rate

Upgrade CCP Master

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

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.
