To test ECUs thoroughly, besides connecting 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 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 test tasks of the VT system are:
- Measurement of output signals (voltage, PWM parameters)
- Display error states such as line breaks or short circuits
- Interconnect original sensors and actuators
- Simulate different loads and sensors
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 I/O lines of the ECU are connected to the modular VT system and if necessary original sensors and actuators too. The PC with the CANoe is connected via a fast, Ethernet-based real-time network port. This makes it easy to build flexible test systems with little integration or wiring effort. The VT system is well suited to both: small test setups at developer workstations and comprehensive test benches in the test laboratory.
