Procedure for updating vehicle software

Abstract

Method for updating software (20) stored in several vehicles (10, 11) that communicate wirelessly with each other and with a stationary computer system (30, 40, 41), wherein a software package (20) of the software is transferred from a stationary computer system (30, 40, 41) to a control unit of one of the vehicles (11), the vehicle (11) is selected depending on at least one status parameter (A, R, D, C1, C2) relating to communication of the vehicle (11), and the software package (20) is wirelessly transferred from the selected vehicle (11) to control units of other vehicles (10) of the vehicles (10, 11), and wherein the stationary computer system (40, 41) is a mirror server, and the status parameters (A, R, D, C1, C2) of the vehicles (10, 11) are transmitted by the vehicles (10, 11). aggregated, with the mirror server for each area assignment (A) and each vehicle (10,11) calculates a product of the communication rate (R) and the mean communication duration (D) as a measure of the communication activity of the vehicle (10, 11) with the area affiliation (A) and also takes into account for each vehicle (10, 11) the quality (C1) of the mobile communication connection as well as a configured WiFi connection (C2), which form a measure of the suitability of the respective vehicle (10, 11) as a multiplier for the software package (20), selects at least one vehicle (11) depending on the aggregated status parameters (A, R, D, C1, C2) (110), determines several software packages (20) for the selected vehicle (11) (120) and provides the determined software packages (20) as well as a package list (26) for transfer (150) to the control unit of the selected vehicle (11) (130, 140).
