ECU Health Monitor Using CANUSB

In automobile an OBD (On Board Diagnostics) facilitates the ECU (Electronic Control Unit) to identify the failures of vehicle systems and take essential corrective actions to preclude the accidents and hazards. Thus the diagnostics empower the driver and passenger safety. During ECU development phase most of the OEMs, Tier-I, and Tier-2 uses a Vector Tool “CANoe” for ECU diagnostics validation. The CANoe tool is very expensive. Its cost is ∼ €10,000. The proposed system is a cost-effective tool that can be used to perform the similar functionality of ECU diagnostics validation during ECU development phase to monitor the ECU health. It uses CANUSB cable as hardware and application software developed in Microsoft C# language. It is the special tool, uses a single channel for transmitting and receiving various CAN messages to/from ECU. Using this tool, the diagnostic request messages and vehicle simulated messages can be sent and response messages can be validated. The tool would be having user-friendly GUI, manual as well as cyclic auto transmission of messages mode and message logging feature. The complete tool cost would be ∼₹35,000.
