Abstract: This paper presents an automated testing of Brake ECU (Electronic Control Unit) – ESP (Electronic Stability Program) communication using canoe tool. Today the number of ECU’s in a car is getting more and more. Besides inner ECU to ECU communication, vehicle to vehicle communication is necessary for the efficient way of vehicular communication. The vehicular communication must be highly responsive and accurate. So ECU testing is compulsory to ensure the efficiency and safety of a vehicle. Testing of an ECU in all aspects like mapping and monitoring of the inputs and outputs with other ECU’s is important. During testing the simulation of all loads and sensors associated with that ECU must be ensured perfectly. Manual testing of these ECU with all these necessary condition is a time consuming process. Vector Tool (VT) help in this need of automated communication testing of an ECU. ECU inputs and outputs for functionality related testing with CANoe is done through the VT. Other ECUs in a car can be simulated using CANoe while testing ECU is compatible for all development stages, due to its high scalability and flexibility. CANoe testing provides high accuracy, reusability and easy way of testing. This total environment is called as Office Test Bench (OTB) where all these vector CANoe box, power supply, ECU, application container (software build), continuous Test framework, master PC (where CANoe software is installed) all are embedded. This setup makes user to test ECU’s very easily and effectively. Basic tests like validation of diagnostic services can be generated automatically in the test configuration tool while complex testing requires manual generation of test cases using script. The test environment is then run on the ECU and a test report is generated for analysis. The test environment is then delivered to a Continuous testing (CT) server and executed on a Continuous test bench (CTB) for every software build. Test reports are stored back in CT server and can be customized to trigger mail at test failure.
