Conformance Tests Compactly AutomatedTest Hardware for CAN and LIN Conformance Tests With CANoe
The VH1160 is a compact USB-based test hardware that automates ECU conformance tests for CAN and LIN. It is typically used by CANoe-based test implementations to automatically reset the ECU on the hardware side before each test case. Current measurement is used to determine the ECU states (sleep/wake-up). The ability to create short circuits on the network line allows you to perform simple tests on the robustness of an ECU.
Advantages
- Easy connection via USB 2.0
- Independent switchable power supply for automotive terminals IGN, Vbatt and GND with immediate status indication by LED
- Easy sleep/wake-up monitoring of the ECU by program-controlled measurement of the current consumption
- Output voltage can be set independently of the input voltage for terminals IGN and Vbatt
- Flexible power supply optionally via standard table-top power supply or laboratory power supply
- Comfortable control from CANoe
Application Areas
To test an ECU, it must first be supplied with voltage. However, a fixed voltage supply, for example via a laboratory power supply, is not sufficient in many cases. For certain tests, terminals have to be switched, an overvoltage or undervoltage set, and possibly the current consumption measured at the same time. The tests themselves may require a time-sensitive procedure that is no longer feasible with manual operation.
The VH1160 was developed for this purpose. With its convenient connection to CANoe it serves as a power supply for ECUs in automated tests and shows its strengths in LIN conformance tests and in the CANoe Test Package VAG, among others.
Functions
- Adjustable voltage from 2...28 V
- Individual control for terminals IGN, Vbatt and GND
- Current measurement from 0...2.5 A
- Ground offset at the ECU and at the LIN line
- Limiting the recessive level of the LIN line
- Short-circuit and interruption options for CAN and LIN lines
- Analog and digital I/O connections
