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.

Description

technical field [0001] The present invention relates to a gateway device for a vehicle that is mounted on a vehicle and performs network connection of information. Background technique [0002] Conventionally, as a device that is mounted on a vehicle and performs network connection (network connection) of information, there is known a system that, for example, is described in Japanese Patent Application Laid-Open No. 2003-101552, by An in-vehicle gateway receives information transmitted from an information center, and transmits information from the in-vehicle gateway through a vehicle control system LAN (Local Area Network: Local Area Network) or a vehicle body LAN. [0003] In this system, when updating vehicle information such as software, the vehicle-mounted gateway stores the update information and performs update management. [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanese Patent Laid-Open No. 2003-101552 Contents of the ...
