Abstract

Provided is a vehicle gateway device capable of smoothly updating information without requiring large memory capacity for the gateway. The vehicle gateway device is mounted in a vehicle and is capable of updating information obtained via external communications, wherein the vehicle gateway device determines whether update information obtained via the external communications is vehicle-related information for controlling a vehicle, and stores and manages the update information if the update information is determined to be vehicle-related information or functions as a gateway and transfers the update information to an information processing unit if the update information is determined to not be vehicle-related information. As a result, the recording medium used when updating information can be of small memory capacity, thereby simplifying information update management.
