For the controller under test, electrical faults in circuits are unavoidable phenomena in practical applications. During the testing phase, electrical faults must be incorporated as part of system testing. This requires the hardware-in-the-loop (HIL) test system to provide equipment capable of simulating different types of electrical faults. The KL2706 Fault Injection Box is a device for injecting faults into physical signal links. It is applicable not only to vehicle electronics but also to aerospace, shipbuilding, power grids, and other fields.

KL2706 has the following main functions:

• Real-time fault simulation

• 64 high-current channels and 16 high-voltage channels

• Fault timing support

• API for customized system integration

• Automated test configuration

• CAN and Ethernet communication interfaces for analog control

• Master/Slave cascade mode for channel expansion

• 80 high-speed fault channels

• Multiple fault types

• FPGA architecture

• Support for fault import/export

• Fault timing

• Hardware and software fault tolerance

• Over-temperature/over-current protection

• Software release testing based on OBD II and other standard specifications

• Diagnostic function debugging

• Testing in virtual real-time environments

• Electrical characteristic testing of black-box electronic control systems

• Testing for chassis dynamometers or static vehicles

• Manual fault injection via host computer software

• Composite fault design using Simulink modules

• Automated operation with other automation tools

• Pin-to-pin faults

• Cable break

• Current leakage

• Loose connection

• Other various faults (e.g., short circuit to ground/power supply, cable break)
