b-plus: automotive data recorder for multi sensor
The recording software AVETO.rec (Automotive Validation Toolchain) is specifically tailored to sensors and control systems of future driver assistance systems and autonomous systems. It has the ability to handle the bandwidths demand of tomorrow’s sensors and ECUS. Reliable data decoupling, data integrity and time synchronization combined with high performance and an easy-to-use web interface. This makes AVETO.rec a highly customizable system for the validation of systems with the highest data traffic.
The AVETO.rec software enables the recording of the sensor data, has a very high logging performance and provides a well-designed interface to the measurement hardware to enable the path to the demanding measurement tasks and to validate the data afterwards. The focus here is to ensure data integrity according to ISO26262-8:2011. In order to ensure the data integrity and to check in the next step. For those integrity checks AVETO.rec adds additional redundancy in the form of a CRC-32C value in each data block.
The AVETO.rec software is based on the robust and powerful BRICK hardware and is ideally optimized for it. In the combination, AVETO.rec is the solution to a scalable system, which can be scaled from the individual ECU logging system application over whole system clusters.
The amount of data of a single sensor, e.g. a camera or a radar, is manageable. If you think of several sensors, which are connected to a central control unit, you will get very high data volumes in the medium double-digit gigabit range. This can hardly be processed with conventional tool chains and systems. For this reason, b-plus offers a complete tool chain based on clusters. The scalable BRICK platforms provide an acquisition data rate per system of 8 GBit/s and a storage unit of 16 TBytes.
