Network Analysis Tool CANalyzer .J1939

Comprehensive ECU and Network Analysis for J1939 Users

SAE J1939 is a communication protocol based on CAN for the data exchange between control units in the area of commercial vehicles. It originates from the international Society of Automotive Engineers (SAE) and operates on the physical layer with high-speed CAN per ISO 11898. J1939 is a multimaster system with decentralized network management and primarily connection-less communication.

CANalyzer .J1939 can be used wherever J1939 networks are developed, diagnosed, and tested. Networks can also be simulated to a limited extent.

CANalyzer .J1939 can be used to monitor and debug other J1939 networks, since the SAE J1939 specification is the basis for NMEA 2000, ISO 11783, ISO 11992 (Truck & Trailer), FMS (Fleet Management System) and GB/T 27930 networks. In combination with the .J1587 Option it offers a uniform approach to systems that extend across bus boundaries with a common time base.

Technical Article: Overcoming Logging Challenges in ADAS Development Projects

The more tasks that driver assistance systems assume along the way to autonomous driving, the greater the number of

sensors in the vehicle from different suppliers. Real road traffic provides the ideal reference data for testing – in endless

variety. For this purpose, OEMs and system suppliers are sending test vehicles equipped with high-end data loggers onto

the streets to collect data. That data is then used to precisely ”re-simulate“ certain traffic situations in the laboratory

to test new or refined ADAS sensing and control logic. Instead of implementing numerous sensor-specific logging systems,

what is required are scalable approaches and strategies.
