Method for wireless remote updating vehicle software

A method is provided for generating a reprogramming file to reprogram a target electronic control unit (ECU) in a target vehicle. High-level language diagnostic commands are generated utilizing a standardized specification language editor comprising Open Test sequence data eXchange (OTX). High-to-low level command conversions specific for the target ECU generate Unified Diagnostic Services (UDS) operation transactions. The high-level language diagnostic sequence commands are converted into imperative language instructions-that are compiled into binary code corresponding to handling routines. A binary image of the target ECU is segmented into a plurality of data blocks. The plurality of data blocks and respective the UDS operation transactions are compiled to provide a plurality of UDS stages that are assembled into the reprogramming file.

A centralized system for real-time monitoring widely distributed software updates of vehicle components, comprises: an arbitration server; a distributed network comprising a plurality of communication servers; a plurality of vehicles, each vehicle of said plurality of vehicles comprising a telematics control unit (TCU) operable to communicate with one communication server of said plurality of communication servers, each TCU is adapted to receive and deploy software updates to electronic control units (ECUs) within its corresponding vehicle, and said TCU is operable to generate status updates for software updates and communicate the status updates to the corresponding communication server; and each communication server is operable to simultaneously receive data messages comprising status updates from the plurality of vehicles and to generate a data stream comprising the data messages, the data stream being sent to a log file.

Centralized system for software updating vehicle components

A method for upgrading vehicle electronic control units (ECUs) in a vehicle comprises: creating a differential upgrade package (DUP) for each upgrade to a predetermined ECU, said creating comprises: comparing a new image of the digital contents of a predetermined ECU flash memory with a present image of the digital contents of the predetermined ECU flash memory; and producing a set of changes to modify the present image to the new image, said changes comprising a set of instructions.
