The calibration and test engineer’s ability to measure and calibrate an ECU’s control and diagnostic parameters depends on reliable access to the ECU. ETAS provides compact modules that connect the ETK/XETK ECU interface as well as the K-Line, LIN, CAN and FlexRay serial buses to the host PC.
The Right Interface
When it comes to the acquisition of a large number of signals, the ETK or XETK is the optimum ECU interface. To satisfy more moderate performance requirements, serial calibration protocols like the ASAM-specified CAN Calibration Protocol (CCP) or its successor, the Universal Measurement and Calibration Protocol (XCP) - which is specified for CAN, FlexRay and Ethernet physical layers - are often implemented on the development ECUs. The calibration of production ECUs is done on the CAN or K-Line diagnostic interface via a diagnostic protocol such as KWP2000. Signal monitoring on the vehicle buses LIN, CAN and FlexRay complements both testing and calibration applications.
All compact ECU and bus interface modules are integrated within INCA. INCA provides for simultaneous acquisition of ECU and vehicle bus signals and data from sensors or analog sources provided by ES400 or ES600 measurement modules.
