Abstract

The invention has been made in order to solve the above-mentioned problems and an object of the invention is to provide a vehicle gateway device that updates information smoothly while preventing an increase in the memory capacity of a gateway. A vehicle gateway device according to the invention is provided in a vehicle and can update information acquired by communication with outside the vehicle. The vehicle gateway device determines whether the update information acquired by communication with outside the vehicle is information for a vehicle system related to vehicle control, records and manages the update information when it is determined that the update information is information for the vehicle system, and transmits the update information to an information processing unit when it is determined that the update information is not information for the vehicle system. In this way, a recording medium with low memory capacity can be used to update information and information update management can be simplified.

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 ...
