Abstract

The present invention provides a gateway performing more efficient reprogramming of multiple controllers and a control method thereof. The gateway includes a processor that authenticates the diagnostic device and utilizes a firmware set including a plurality of different firmwares corresponding to a function and authentication information about the firmware set received from the diagnostic device when authentication of the diagnostic device is completed. , the authentication firmware group. In addition, a plurality of different firmwares included in the certified firmware group are respectively transferred to a plurality of controllers corresponding thereto.

Description

technical field [0001] The present invention relates to reprogramming of in-vehicle controllers, and more particularly, to a gateway capable of performing more efficient reprogramming of multiple controllers and a control method thereof. Background technique [0002] More recently, many nodes of a vehicle network include electronic control units (ECUs) such as Body Control Module / Electronic Time and Alert Control System (BCM / ETACS), Antilock Brake System ECUs configured to manipulate electronic and chassis components (ABS ECU), engine ECU, airbag ECU. These ECUs perform vehicle diagnostic services for safe and economical vehicle driving, thereby avoiding car breakdowns, and are also configured to receive various types of vehicle information, such as vehicle driving record management and statistical information. In addition, the ECU can be configured to receive software upgrades (ie, reprogramming) as needed, such as changes in instructions and upgrades in functionality. Th...
