TTX-DataLogger: State-of-the-Art Technology for Vehicle Testing and Validation

TTX-DataLogger

With TTXDataLogger, TTTech Automotive, a subsidiary of TTTech and specialist for safety controls and reliable networking, as well as manufacturer of electronic control systems for electric vehicles, brings a recording tool to the market that exceeds today's most demanding application profiles. As a high-performance, open and scalable platform, this data logger is prepared for future requirements. The technology within this product motivated AUDI AG to act as a development partner.

Through its innovative concept, TTXDataLogger sets new standards for securing and troubleshooting in the automobile. The unit meets criteria such as ease of use and flexibility, and provides the availability of recorded data of all current bus systems that are synchronized by a central time stamp. For different application profiles TTXDataLogger allows holistic and selective recording at the same time, and has an integrated diagnostic interface. Using the established measurement and calibration protocols CCP and XCP, internal ECU signals can also be recorded. Following the data for a complete and consistent analysis are provided.

"The bar for test equipment at Audi is very high because they are an integral part of our quality system," says Ricky Hudi, Head of Electrics/Electronics at AUDI AG. "In addition to comprehensive functionality and absolute reliability, aspects such as ease of operation and a simple, consistent interpretation and analysis are important to us. The TTXDataLogger simplifies the recording on board as well as the subsequent evaluation. I am pleased that we were involved in the successful implementation of such an ambitious development."

TTXDataLogger can also be operated remotely from the test bench. An open operating system platform (Linux) ensures that existing test and evaluation functions are easily integrated. OEM-specific requirements can be added upon request. An open data format enables reading of traces with common tools such as CANoe. In addition to the possibility to use external storage functions such as USB disk and CF card, the device has a large onboard memory for recording with a storage capacity of 64 GB as standard.

"In addition to the implementation of the comprehensive feature set on the device itself, absolute reliability and unlimited and convenient use of the test tool during testing are our main focus," says Dr. Stefan Poledna, Managing Director of TTTech Automotive GmbH. With a remote control, having the same functionality as the device itself, TTXDataLogger can be used in the passenger compartment while driving. Using a mark button (manual trigger) and audio recording, abnormalities can be documented directly with the remote control. This simplifies the subsequent analysis.
