To test ECUs thoroughly, it is not only necessary to connect the the communication networks to the test system, it is also necessary to connect the I/O interfaces.
This task is handled by the Vector VT System. It simplifies the setup of test benches and HIL test systems immensely, because it integrates all circuit components needed to connect an I/O channel in one module. Examples of I/O channels are an ECU's output for controlling a headlamp or input for connecting a brightness sensor.
Typical tasks of the VT System are:
The modules are designed for voltage ranges typically used in the automotive field, and they can also handle high currents such as those that may occur in driving lamps and motors.
The VT System - now with 2 new modules:
