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.

Abstract: Calibration for a vehicle electronic control unit (ECU) includes determining a trigger event configured to initiate a check for updates to calibration data files of the ECU, iterating through calibration part numbers present in the ECU, and accessing, from a memory device in communication with the vehicle, in response to the iterating, a chain of parts table in a linked list that maps calibration part numbers identified in the ECU unit to any subsequently-issued calibration part numbers. The subsequently-issued calibration part numbers reflect an index to the updates to the calibration data files. The calibration also includes searching the chain of parts table using the calibration part numbers identified in the ECU to determine a corresponding subsequently-issued calibration part number, selecting one of the updates to the calibration data files using the subsequently-issued calibration part number from the memory device, and updating the ECU with the selected update.

Abstract: A method for adjusting a variable rate of requesting software data for a computer system onboard a vehicle is provided. The method determines a number of ignition cycles executed after first software data has been retrieved; and when the number of ignition cycles is greater than a threshold value, reduces a frequency for generating a software request, to obtain a reduced frequency.

Abstract: A system, computer-program product and computer-implemented method of updating a software configuration of a vehicle. A communication interface communicate with a plurality of electronic control units (ECUs) of the vehicle, and a processor. The processor performs an updating operation on the plurality of ECUs to change the software configuration for the plurality of ECUs from a first software configuration to an intended software configuration, identifies at least one ECU from the plurality of ECUs that fails to update to the intended software configuration after performing the updating operation. The processor rolls back the at least one successfully updated ECU to the previous version of software configuration.
