The Mahle Data Recorder 2 (MDR-2) from Mahle Powertrain is an in-vehicle PC capable of autonomous operation. Based on the Windows XP operating system, the device acts as a high-rate data recorder for powertrain control system development and validation, supporting industry-standard calibration software tools. Suitable for other in-vehicle PC uses, the MDR-2 features a wake-up circuit and real-time clock, allowing user-defined events to initiate boot up from trigger options such as receipt of CAN bus messages, voltage transitions, or preset times of day. Intelligent options combined with continuous vehicle battery monitoring prevent charge depletion and no starts. The rugged recorder withstands harsh vehicle environments and includes support for most peripheral devices, while a 3G air-card remotely connects to the MDR-2 and allows reconfiguration of recorder channels, file transfer, and ECU reflash from a desktop PC or iPhone.
