CANdesc Software Component for Diagnostics The diagnostic functionalities and diagnostic data for an ECU are described in the specification phase using CANdelaStudio and stored in a consistent database (CANdela). This ECU diagnostic specification can directly be used to generate the CANdesc code. Changes in this specification during the vehicle development can therefore be cost-efficiently updated in the ECU by a simple regeneration. This guarantees that the specification and the implementation always fit together. The vehicle and ECU manufacturer can use the CANdela data base also for parameterization of test systems. Thus a continuous process chain beginning with the specification, continuing with implementation and finishing with integration and functional testing can be offered. Vector’s CANdesc (desc = diagnostic embedded software compo-nent) enables vehicle and electronic control unit (ECU) manu-facturers to implement the diagnostic protocol uniformly across different OEMs and their vehicle lines. CANdesc supports diagnos-tic communication via CAN, MOST, FlexRay. Any other bus system will be also supported using an optional abstract transport layer interface. CANdesc can be ordered seamlessly integrated in the CANbedded world and also for stand-alone usage in a supplier-specific environ-ment. 2/8 To guarantee efficiency for different OEMs and vehicles, CANdesc is fully generated code. The generation process is based on the project-specific CANdela data base. To ease and speed up the usage, a diagnostic code template is generated which fully implements all interfaces. Using this tem-plate ECU Manufacturers: CANdesc covers the vehicle manufacturer diagnostic protocol and transported data completely. This assures that > timing and content requirements of the diagnostic protocol are implemented correctly. > simplification of a product line concept in the diagnostic area in spite of multiple ECU variants and vehicle manufacturers is possible > development costs for implementation and testing effort are reduced > Predictability of the correct and complete diagnostic implemen-tation a basically working diagnostic implementation is immedi-ately available. Features and Advantages Vehicle Manufacturers: CANdesc offers assurance to the vehicle manufacturer that the diagnostic specification is implemented uniformly in all ECUs of a vehicle model. Using CANdesc and CANdelaStudio, the comprehensive CANdela approach to diagnostics (see also product description for CANdela – CANdelaStudio), provides the greatest benefit. is significantly increased.
