The supplied software takes care of communication and downloading to the control units. When an update is available, the onboard manager receives the data before the on-board tester takes care of diagnostics and flashing. ”It has all the processes for flash updates“, explains Pranschke. “It can therefore update all flashable control units in the vehicle.” With IAV’s solution, existing vehicles can be made fit for ORU, retroactively and with manageable effort. It goes without saying that data can also be transferred in the other direction. A logbook app, for example, uploads vehicle data from various test vehicles to a database server by wireless connection. “The hardware and on-board tester are ideal at the moment for test fleets. But there is also the possibility of further development to make it a standard solution”, emphasizes Pranschke. Adjustments will of course have to be made in line with specific projects and vehicles.
IAV is working with its customers to develop and test various aspects, among others how to organize the authentication process for updates, what should happen if flashing is interrupted and which preliminary conditions have to be fulfilled for programming. Here a test environment is being used that includes rest bus simulation for analyzing data transfer and for detecting or simulating errors during flashing. “We are thus able to give our customers support on a one-stop shop basis”, summarizes Pranschke. “We cover the entire transmission chain, from backend via wireless connection transmission and reception in the vehicle right through to downloading the data into the control unit.
