103 testing in the lab, on the test bench, and in test vehicles. These solutions are specifically designed for automotive use, and they work at any temperature, from arctic cold (-40 °C) to tropical heat (+70 °C). A uniform, robust housing with a plugin connection ensures clear, uncluttered integration. Stacking the modules one on top of the other ensures a reliable shared power supply and internal Ethernet data connection, minimizing wiring work and simultaneously solving issues such as synchronization, wake-up, and shutdown. When cables do have to be plugged in, their connections are secured by robust LEMO connectors. The hardware modules also come with a PCI Express bus system. The ETAS ES820 Drive Recorder is one of the latest additions to the strictlymodular ES800 hardware family. Replacing an on-board laptop or INCA PC, it records all data and signals from ECUs, buses, networks, sensors, and measuring instruments for over 22 hours. Recording can begin when the engine starts; alternatively, it can be preprogrammed for certainmeasurement durations or trigger mechanisms, or ini- tiated by the developers on a situational basis. Since the Drive Recorder – like all the hardware family modules – is com- patible with ETAS INCA, developers and calibration engineers can design, test, and modify these mechanisms directly in which- ever standard tool they prefer before putting them to use in the Drive Recorder. The ad- vantage is that they can stick to familiar pro- cesses while gaining access to a whole host of additional functions for validating future development projects. Full support for seamless processes Validating the increasingly complex interac- tion between connected electronic vehicle systems is a major undertaking that requires drastic increases in the amount of testing and measurement work. Comprehensive doc- umentation is essential, since many of the systems are relevant for the safety of vehicle occupants and for type approval. Fortunately, the ES820 Drive Recorder makes it easy to fulfill these requirements. Thanks to an ex- changeable storage system with a capacity of up to one terabyte, the ES820 can capture all the data and measurement signals from an entire test drive and easily copy the results to the relevant in-house networks. The mea- surement data can be copied across at 200 megabytes per second using a suitable dock- ing station. That means a full one terabyte hard disk can be ready for its next job in 30 minutes or less, and the specialists in the var- ious departments involved can access the data immediately. This interchangeable system also enables seamless operation across mul- tiple layers with different hard disks, paving the way for faster, more in-depth validation and eliminating delays between test drives and analysis. To facilitate comprehensive datalogging on all channels, the ES800 system has connec- tors for ETK, FETK, and XETK interfaces, as well as all standard vehicle buses. That makes it easy to expand the system by connecting CAN, CAN FD, FlexRay bus, and Automotive Ethernet to the ES820 via its USB ports. All this is backed by a powerful Intel i5 processor and four gigabytes of working memory to en- sure fast data processing. These specifications allow the Drive Recorder to be seamlessly in- tegrated into existing toolchains and provide a good basis to meet future needs, particu- larly in view of new legal requirements – such as measuring real driving emissions (RDE) – which will see even sharper increases in the depth and complexity of measurement and validation processes. Broad basis for intelligent reuse of measured data The broad range of data captured synchro- nously by the ES800 family of products facil- itates precise, in-depth validation. Combined with deep learning and big data methods, it also paves the way for the intelligent reuse of measured data. Recording this data end-to-end will create an increasingly comprehensive database as each project is completed. This will give users ever deeper insights into development and calibration, resulting in faster and more reli- able validation. Systematically reusing data and executing measurement tasks in parallel reduces both overhead time and the need for expensive test vehicles. The ES820 Drive Recorder supports this op- tion through the simultaneous multi-record- ing of multiple vehicle functions. To achieve this, an ensemble of measurement signals and various start and stop triggers can be assigned to each individual recorder. The recorders then run in parallel, storing the respective data in separate measurement data files at rates of up to 13 megabytes per second – a largely au- tomated process that captures and records a comprehensive snapshot of in-vehicle pro- cesses. This is facilitated by four digital inputs and outputs on each device; the inputs can be used as triggers or markers, and the outputs for displaying system status and event mes- sages. INCA-TOUCH promises user-friendly operation and advanced connectivity With its advanced functions, the ES820 Drive Recorder will replace the laptops and displays currently used in the field. That’s good news, because operating laptops and similar devices during test drives can pose a serious safety risk. To ensure users can keep track of devel- opments and interact with the measurement system even while on the move, ETAS is developing a solution that works in combina- tion with INCA-TOUCH. This solution enables dedicated values measured by the Drive Re- corder to be shown on a display. As well as user-friendly operation, another key factor is connectivity. Just like so many other devices, measurement and diagnostic systems are part of an increasingly connected world. Modern vehicles, whether on the road or on- line, are also deeply embedded in the global flow of data. In the context of the new Drive Recorder, this connectivity will enable engi- neers to make adjustments while sitting at their desks – and even access data wirelessly where necessary. In this case, the data will be transmitted to a predetermined FTP/SFTP/ FTPS data server. These kinds of remote functions were made available in the course of 2018 and will be gradually expanded in the future. With the ES820, developers are well equipped for the future flood of data.
