車両診断通信[Probably the last article] Vehicle Diagnostic Communication Part 99 [Looking Back]
Brief look back. The vehicle diagnostic communication has a wide range of use cases, which makes it a broad topic. This series is now over.
車両診断通信[CAN-FD] Vehicle Diagnostic Communication Part 98 [AUTOSAR 3]
Simulation of AUTOSAR-Dcm was executed. Simulation of AUTOSAR-Dcm, the basic principle is the same, except for the maximum message length. Simulation of AUTOSAR-CanTp. Both request and response behaved according to CAN-FD rules.
車両診断通信[CAN-FD] Vehicle Diagnostic Communication Part 97 [AUTOSAR 2]
Fixed the configuration of AUTOSAR-CanTp for CAN-FD. Fix configuration of AUTOSAR-Dcm for CAN-FD.
車両診断通信[CAN-FD] Vehicle Diagnostic Communication Part 96 [AUTOSAR 1]
Click here for back issues. Introduction. The policy for simulation of CAN-FD in AUTOSAR will be explained. Simulation P...
車両診断通信[CAN-FD] Vehicle Diagnostic Communication Part 86 [Overview 2]
Simulation procedure and intuition explanation. CAN-FD control with python-can. CAN-FD diagnostic communication with can-isotp (ISO15765-2). CAN-FD diagnostic communication with AUTOSAR-CanTp (ISO15765-2). AUTOSAR-Dcm for CAN-FD diagnostic communication (ISO14229-1).
車両診断通信[CAN-FD] Vehicle Diagnostic Communication Part 85 [Overview 1]
Switch from CAN to CAN-FD for the physical and data link layers. CAN-FD is described in Vector's "CAN/CAN-FD for Beginners".
車両診断通信[Dcm] Vehicle Diagnostic Communication Part 84 [Simulation 23]
We saw a pattern of returning NRC$10 (generalReject) when NRC$78 (ResponsePending) exceeds a certain number of times. This specification is not specified in ISO 14229-1. However, it is likely to be a de facto standard. Therefore, it is assumed that it is incorporated as an AUTOSAR specification.
車両診断通信[Dcm] Vehicle Diagnostic Communication Part 83 [Simulation 22]
Check the results of the WriteDataByIdentifier simulation. Confirmation of the message. Confirmation of CAN line. Often used in conjunction with ReadDataByIdentifier to check operation for reading after writing. NRC$78 returned atmosphere. In fact, NRC$78 is rarely followed three times.
車両診断通信[Dcm] Vehicle Diagnostic Communication Part 82 [Simulation 21]
I wrote Python code to simulate WriteDataByIdentifier. WriteDataByIdentifier is often protected by session and security, so the main test is to test it.
