| description | The invention discloses a method for updating vehicle ECUs using differential update packages. 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. The DUP comprises a set of instructions that are utilized to update the ECU flash memory a block at a time.
本发明公开了种用于使用差分更新包更新ECU的方法。种用于升级车辆中的车辆电子控制单元(ECU)的方法包括：创建用于对预定ECU的每个升级的差分升级包(DUP)，所述创建包括：将预定ECU闪存存储器的数字内容的新图像与预定ECU闪存存储器的数字内容的现有图像进行比较；以及产生组变化以将现有图像修改为新图像，所述变化包括组指令。DUP包括被用于次块地更新ECU闪存存储器的组指令。 |
