Hardware for ECU Testing To perform system and ECU tests you need special test hardware. The hardware modules offered by Vector let you execute reproducible test cases. This way you can obtain high-quality test results including results for bus physics analysis and for stress tests on the physical and protocol levels. VT System VT System is a modular system of interface hardware to access the I/O lines of an automotive ECU for testing purposes with CANoe. It is designed for testing ECUs in the automotive industry. The VT System can be used to connect original actuators and sensors to the ECU or to simulate them entirely. Activities on the I/O lines are measured and routed to CANoe. CANister Use CANister as a flexible and user-configurable operating panel for controlling CAN and LIN buses and for displaying bus events. CANstress In the scope of comprehensive system or ECU tests, specific behavior in response to disturbances or failures should also be checked. This is done by stressing the CAN bus with CANstress, modifying its physical properties and logical bus level. 4/0 FRstress In analyzing and testing FlexRay systems, it is necessary to exam-ine system behavior more precisely in response to errors and dis-turbances. Use FRstress to generate reproducible disturbances on one channel in the FlexRay cluster. Both protocol errors and dis-turbances to the bus physics can be generated. CANscope Many different physical parameters affect the signal level on the CAN bus. Use CANscope to measure, record and evaluate signal levels.
