Vehicle network architecture is changing. Following the transition from the classic architecture to domain architecture, now zone-based architecture is about to be introduced: Ethernet is constantly growing in importance in vehicle networking; established bus systems such as LIN remain and others are enhanced like CAN-FD. Dedicated buses like FlexRay or MOST are declining in importance. In addition, there are application-specific interfaces, such as LVDS for cameras. These include FPD-LINK III, GSML2, and A-Phy.

All data loggers of our CCA 9010 and CCA 7010 product families are ideal solutions for adapting flexibly to these new architectural requirements due to the principle of Distributed Data Logging and the reliably high recording rates.



Scalable and adaptable

Different setups with capture and measuring modules can be used based on the project requirements. The user interface, software toolchain and accessories are identical for the compact devices of the CCA 7010 and the high-performance devices of the CCA 9010 series.

Developed for use in vehicles

Their robust design allows the CCA data loggers to be used in tests that are challenging for both vehicle and measurement equipment, whether in climate and endurance tests or in field operational tests (FOT). The CCA data loggers have an integrated power supply unit with low idle power consumption and configurable wake-up function that was developed specifically for use in vehicles. The CCA distributed data logging systems support vehicle manufacturers in ensuring the highest level of vehicle quality.

Targeted recording

There are often different internal or external customers for the data recorded during complete vehicle validation. The CCA data loggers make it possible to group the data sources and establish a data format for each group individually. In addition, you can also select continuous or trigger-based recording. Thanks to the various options for generating triggers manually, automatically or based on scripts, as well as the up to 200 GB RAM of pre-trigger memory, the required data can be recorded in a compact and targeted manner. This means that data is already pre-sorted in the data logger and can be forwarded directly to the correct addresses without tedious conversion or filtering steps.

Power reserves for ADAS and AD

Depending on the testing strategy, it can make sense to record selected or full raw sensor data (from cameras, radar, etc.) during the whole vehicle validation. This allows a more in-depth fault analysis, since problematic driving situations can be simulated in HIL or SIL systems. It also makes it possible to use test drives that are taking place anyway to broaden the data available for training and safeguarding of autonomous driving functions.

For the BMW Group, the central prerequisite for highly automated driving is the development of safe driver assistance systems. The extremely powerful data loggers from ViGEM have been used in our test vehicles for years. They record the huge amounts of data required for this reliably and uncompressed.
