Scalable and Modular Systems for Efficient HIL Testing

VT System

To test ECUs thoroughly, it is not only necessary to connect 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. 

Advantages

  • All relevant test components are integrated into a single device:

    • Measurement hardware with signal conditioning
    • Relays e.g. for switching short-circuits

    • Electronic load for actuator simulation

    • Resistance decade for simulation of a sensor

  • Minimal wiring effort for test setups

  • Voltage range adapted to automotive applications

  • Seamless integration into CANoe

Application Areas

With the VT system test systems for the function test of ECUs and vehicle networks can be assembled. CANoe is the associated test automation software.
The modular design of the VT System allows to build test solutions ranging from simple test setups to complex test systems:

  • Dedicated test systems for individual ECUs
  • Universal function testers for ECUs and subsystems
  • Flexible test hardware for the developer's work station

VT System Concept

When performing functional testing the ECU has to be tested in an environment in which it can see no difference between the real vehicle environment and the testing environment.

The I/O lines of the ECU are connected to the modular VT System and when 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.

 

ECU environment in the vehicle

In the vehicle, an ECU communicates with other ECUs via bus interface; it is supplied with power from the battery and is connected to sensors and actuators via I/O lines.

Testing with original loads and sensors

The VT System is placed between the ECU's I/O lines and the original sensors and acuators. CANoe executes the automated tests and simulates the rest of the network nodes.

Testing with simulated actuators and sensors

The VT System can also simulate the sensors and actuators. This lets you reconstruct any desired test situations and error cases.

Modular Test Racks

Housing

The VT System is highly scalable. It can be used to set up test systems that range widely in complexity and functionality: from small auxiliary test tools at developer workstations to comprehensive functional testers and HIL test stations in the test laboratory.

Since the modules are universal in design, the test systems can be used for different test objects and test tasks without much effort.

Backplane

The backplane takes up the lower quarter of the housing height. In the space above, the plug-in modules of the VT System are directly accessible from the back.

The backplane provides the Ethernet connection for the CANoe PC and supplies the VT System modules with 12V operating voltage. Each installed VT System module is also connected to the EtherCat® bus through the backplane. With the second Ethernet connector, several VT System racks can be connected to bigger test systems. Vector also provides completely assembled test racks on a project basis.

User Programmable FPGA

Some VT System modules are available as FPGA variant with a processor board which includes a second, user programmable FPGA. This FPGA has access to the I/O hardware on the VT System modules and communicates with CANoe and therefore allows the implementation of customer specific functionality.

     

  • Measurement data conditioning or signal generation, which cannot be covered with the standard VT System modules functionality

  • Time critical functions can be sourced out to the FPGA hardware instead of executing them software-based with CANoe

  • Description of FPGA functionality with VHDL or via graphical schematic entry with Simulink®

  • Easy development and management of FPGA projects by support of VT System FPGA Manager
