At present, with the increasing demand of consumers for infotainment system and autopilot system, there are more and more electronic control units in the car, and the information interaction is becoming more and more complex. In this context, vehicle Ethernet is expected to become the backbone network of intelligent connected vehicles in the future because of its higher data transmission bandwidth, more flexible connection architecture and more powerful iterative upgrade ability. As a professional database design and editing tool, Jingwei Hengrun INTEWORK-VDE (Vehicle Database Editor) tool corresponds to the system design stage of V model, and provides support for subsequent parts design with general data interface. VDE develops the function of Ethernet communication design on the basis of supporting CAN (FD) and LIN, which can support SOA design and SOME/IP-based communication system design, quickly and easily define data type, service definition, service deployment, and communication behavior definition of SOME/IP and SOME/IP-SD, and provide a lightweight agile development environment for vehicle network engineers.

Product introduction

As a tool for network communication design based on the whole vehicle, VDE can support the design of CAN (FD), LIN and Ethernet, and support the export, comparison, generation of ChangeLog, gateway routing table, consistency check, database audit and version management of communication databases (DBC, LDF, ARXML). The Ethernet function of VDE is another important function after the basic edition. its purpose is to provide users with a friendly Ethernet database editing platform, which can easily realize the creation of Ethernet database. The ARXML file exported by VDE meets the requirements of AUTOSAR specification, and supports import to CANoe, DaVinci, SWCDesigner and other tools for simulation testing, code generation and so on. In addition, VDE can also meet the more flexible needs of users by implementing the import, editing and re-export of ARXML. Data type definition ♦ supports defining multiple data types such as BaseType, Enum, Array, String, Struct, Union, etc. ♦ supports setting the data members, maximum and minimum values of DataType, Unit and other information ♦ support fuzzy search and filtering of DataType ♦ support tabular overall view of data types ♦ support tree expansion complex data type service definition ♦ support setting services and instructions related ID ♦ support defining specific service content That is, three instructions: Method, Event and Field ♦ support setting instruction transmission parameters, transmission protocol and Eventgroup and other information ♦ supports viewing service interface service deployment ♦ configurable service provider and consumer in the form of Client-Server and Sender-Receiver interfaces to achieve service deployment ♦ can set communication parameters related to service provision and consumption ♦, such as port number and instance ID, can set SOME/IP-SD parameters related to the service instance VLAN configuration ♦ can set basic properties such as VLAN ID, priority, etc. ♦ can set VLAN related SOME/IP-SD Multicast address ♦ can be VLAN divided according to ECU, VLAN can be divided into vehicle topology and ECU configuration ♦ can be flexibly configured ECU IP, MAC, Port and other information ♦ can configure ECU with internal integrated switch ♦ can set topological connection relationship between ECU VLAN Membership convenience feature of switch can be generated automatically based on topological connection relationship and VLAN configuration ♦ support undo restore Undo/Redo function ♦ supports consistency check of Ethernet communication design ♦ supports dragging and adjusting the order of data members ♦ supports default parameter settings through Excel
