A new one-stop automated testing experience

LIN Conformance Testing System

TOSUN CAN (FD)/LIN Conformance Testing System provides a complete in-vehicle network testing solution through hardware standardization, software platformization, and use case modularization architecture design.

LIN Conformance Testing System

Highly integrated, one-step testing

This system is based on TOSUN's independently developed bus analysis tools, jammers, and special chassis for conformance testing, combined with standard peripheral instruments and equipment such as programmable power supplies, oscilloscopes, and digital multimeters, to form a highly integrated conformance testing system.

In terms of software, the test logic required by the specifications is implemented based on the TSMaster test script. Through program control calls to the hardware system, it fully supports the automated conformance testing and test analysis reports of the following three points for automotive parts LIN nodes.

  • Physical layer
  • Link layer
  • Application layer (node management, scheduling table, fault tolerance, flashing, UDS diagnostics)

Quoted Standard

  • LIN2.x
  • ISO 17987
  • GB/T 42691
  • GEELY 3.0/3.5 Enterprise Standard
  • BYD Enterprise Standard
  • SAIC Enterprise Standard
  • ISO 14229-7

Highly integrated

One device for conformance testing and network automation testing related content

Highly automated

Turn on automated testing with one click.
Automatic generation of detailed test reports upon completion

scalability

Easy to expand, modify report templates, and add new applications in the future

reusability

High script reusability, independent parameter configuration, simplifying adaptation work for different projects
