Abstract: Technical solutions are described for updating a plurality of electronically controlled units (ECU) in a vehicle with multiple communication buses. An example method includes determining an installation order for updating the plurality of ECU based on a priority level assigned to each of the ECU, and a size of each update package for each of the ECU. The method also includes updating the ECU concurrently by installing the respective update packages according to the installation order.
