TOOLS FOR NETWORKS AND DISTRIBUTED SYSTEMS VT System I/O Interface Modules for the ECU Test Functions The VT System is connected to the ECU in place of the actuators or sensors. The loads and sensors are simulated by the VT System modules. However, the signals can also be connected to the origi-nal Overview of 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 cabling effort for test setups > Voltage range for automotive applications > Seamless integration into CANoe actuators and sensors. All components required for testing the connected ECU´s inputs or outputs are integrated into the VT System modules: > Relays for switching various signal paths (e.g. internal or external load) > Creation of short-circuits between the two signal lines, to ground or battery voltage > Simulation of loads or sensors > Measuring unit with signal conditioning > Connection of additional measurement and test devices via two additional bus bars > Clear status display on the front panel An ECU has numerous I/O interfaces to which actuators and sen-sors can be connected. A modern and flexible test system must operate these interfaces and acquire data during the function test. Application Areas With the VT system you assemble test systems for the function test of ECUs and vehicle networks. CANoe is the associated test auto-mation As all channels are connected via two wires, the system supports all relevant input and output types, even motors controlled in the ECU via an H-bridge circuit, for instance. The characteristic technical data of the modules like the allowable current and voltage ranges have been specially configured for the requirements of testers in the automotive field. software. The modular design of the VT System allows you to build test solutions ranging from simple testing setups to com-plex testing equipment: > Dedicated test systems for individual ECUs > Universal function testers for ECUs and subsystems > Flexible test hardware for the developer’s work station Fully populated rack of the VT System up to 12 modules and one backplane fit in a 19 rack V2.14 2012-04 More Information: www.vector.com/contact
