Abstract

A gateway which performs more efficient reprogramming of a plurality of controllers and a control method thereof are provided. The gateway includes a processor that authenticates a diagnostic apparatus and a firmware group that includes a plurality of different firmware corresponding to one function using the firmware group and authentication information regarding the firmware group received from the diagnostic apparatus when authentication of the diagnostic apparatus is completed. In addition, the plurality of different firmware included in the authenticated firmware group are transmitted to the plurality of controllers corresponding thereto, respectively.

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...
