During the development process, software developers use calibration and data acquisition techniques to “fine-tune” the ECU (Electronic Control Unit) for specific operating conditions. Standards are available for measurement and calibration of an ECU. Measurement and calibration is commonly done via serial data links. The serial link used in modern ECUs is CAN (Controller Area Network). One requirement for the use of standard protocols on a CAN network is the need for two CAN identifiers. To help raise the awareness of the need for a fixed assignment of CAN identifiers for use in development, and perhaps extending into manufacturing, this paper gives a short technical background on how standard measurement and calibration protocols use the CAN identifiers and suggests several potential SAE proposals for assigning fixed CAN identifiers for the industry.

Learning OSEK's three reusable software components is no simple task especially for those just beginning with distributed embedded system technology. With the details set aside, this technical paper focuses on introducing just one of the OSEK components, the Network Management (NM), and attempts to help the reader understand its basic concepts.

Providing the capability to Flash program using a CAN network connection is the subject of this paper. The focus is on creating a simple monitor program that allows an external tool to interact with any individual module or ECU on a CAN-based network.

While the CAN Calibration Protocol or CCP is a reasonably well known standard in Europe that continues to gain acceptance, its exposure in the American automotive electronics arena has to some extent been limited to the engine calibration area. A closer examination of the protocol reveals that the CCP is not just for calibration. With many general-purpose features including flash programming capability, the CAN Calibration Protocol is useful for a wide range of module development activities. CCP users have access to online measurement data and the ability to calibrate modules. This allows software development to occur not only in a lab environment but also during an in-vehicle test. Even though U. S. companies using or evaluating the CAN Calibration Protocol include DaimlerChrysler, Ford, GM, Delphi, Motorola, TRW, Visteon, and several others, many product development engineers are unaware of this potentially reusable software.
