Vehicle Network Toolbox proporciona funciones de MATLAB y bloques de Simulink para enviar, recibir, codificar y descodificar mensajes CAN, CAN FD, J1939 y XCP. La toolbox permite identificar y analizar señales específicas mediante archivos de base de datos CAN estándar del sector y luego visualizar las señales descodificadas con las apps CAN Explorer y CAN FD Explorer. Mediante archivos de descripción A2L, puede conectar con una ECU a través de XCP en CAN o Ethernet. Puede acceder a mensajes y datos de mediciones almacenados en archivos MDF.

La toolbox simplifica la comunicación con redes de vehículos y permite supervisar, filtrar y analizar datos de bus CAN en tiempo real o registrar y grabar mensajes para su posterior análisis y reproducción. Puede simular el tráfico de mensajes de un bus CAN virtual o conectar con una red o ECU en tiempo real. Vehicle Network Toolbox soporta dispositivos de interfaz CAN de Vector, Kvaser, PEAK-System y NI®.

CAN Communication

Configure and establish connections to a CAN bus using CAN or CAN FD protocols then send, receive, encode and decode CAN messages. These messages can be logged for offline analysis and replayed in another Simulink model.

Three Simulink windows showing how to acquire measurements from an ECU slave device. The model uses XCP Configuration and XCP Transport Layer blocks (top), and XCP Data Acquisition blocks (bottom right) to configure the acquisition of the PWM signal (bottom left).

XCP Protocol

Communicate with ECUs using the XCP protocol via CAN, CAN FD, or Ethernet. Read and write data to specific memory locations within the ECU, and link A2L files to perform calibration and measurement tasks.

J1939 Protocol

Set up communication via the J1939 protocol, including associating a database file, specifying CAN interface hardware, transmitting and receiving J1939 parameter groups, and encoding and decoding signal data.

CAN and CAN FD Apps

Use the CAN Explorer and CAN FD Explorer apps to visualize active traffic on a specific CAN channel, decode messages and display them in engineering units.

MATLAB Live Script showing how to access information stored in A2L files for use with XCP connections.

A2L Description Files

Use A2L (ASAP2) description files to communicate with ECUs over XCP protocol from MATLAB or Simulink. These files contain information about memory address, data type, and rules for converting stored values into physical units, simplifying calibration and measurement tasks.

MDF Files

Easily import and export MDF files, view basic properties, create MDF files, and write timetable data to existing MDF files. You can read in subsets of MDF files and create a datastore to work with large files.

Decode and Write CAN data to MDF files

Documentation | Examples

Simulink model showing the use of MathWorks virtual channels to send and receive CAN data without any hardware.

Virtual Channels

Use virtual CAN and CAN FD channels to simulate network communications in a loopback configuration without physical hardware. Use MathWorks virtual channels or those from third-party vendors like Vector and Kvaser.

Implement Distributed ECU Network over CAN in Simulink

Example

Code example showing how to view messages using information stored in CAN database files.

Vector CAN Database Files

Associate Vector CAN database files with CAN channels or messages in MATLAB or Simulink to decode and encode CAN messages using application-specific names, scaled engineering units, and predefined signal parameters such as start bit, length, and byte order.

Use DBC files in CAN Communication

CDFX Files

Access data in ASAM calibration data format (CDFX) with the cdfx function provided by Vehicle Network Toolbox. Use calibration data from a CDF file as inputs to a Simulink model.
