      Vector D-PDU API

      The Vector D-PDU API is a programming interface, standardized in ISO 22900-2, for accessing a Vehicle Communication Interface (VCI).

      Vector D-PDU API abstracts from the underlying VCI, especially from implementation of the communication protocol.

      As a result, an application which is based on a D-PDU API can be created independently of the VCI and in particular without a dedicated implementation of the communication protocol.

      Advantages

      Use of existing hardware

      • Already existing Vector network interfaces can easily be extended with the Vector D-PDU API and are immediately ready for appropriate applications.

      Optimal performance

      • The Vector D-PDU API uses the flexibility and features of the powerful Vector network interfaces. Therefore, it offers optimal performance for your applications.

      Simultaneous communication

      • The Vector D-PDU API can share one channel of the Vector network interfaces with other Vector tools. So a customer-specific application can access the bus over the D-PDU API, while for example CANoe, CANalyzer and/or CANape run measurement or analysis tasks on the same channel. This eases for example also the troubleshooting in D-PDU API based applications.

      Cost-effective solution

      • Vector D-PDU API is a cost-effective solution especially for OEMs and suppliers who already use the Vector network interfaces and who are additionally use or develop ISO 22900-2-based applications. Therefore, the Vector bus interfaces can also be used for customer-specific diag-nostic and flash applications. An additional VCI hardware is no longer required.

      Application Areas

      Application architecture with use of the D-PDU API
      Application architecture with use of the D-PDU API

      The D-PDU API from Vector is used in the field of ECU development and diagnostics to create various OEM-specific applications such as diagnostic testers. 32-bit or 64-bit applications can be developed flexibly and efficiently based on the 32-bit or 64-bit library. It lets developers focus on the application logic.

      In addition, the D-PDU API enables the use of Vector network interfaces in applications that are based on an ISO 22900-3 conformant diagnostic server.
