Abstract

A vehicle gateway device 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.

Claims

1. A vehicle gateway system that is provided in a vehicle and can software update information acquired by communication with outside of the vehicle, comprising:

a first device including;

a central processing unit (CPU) programmed to determine whether the software update information acquired by communication with outside of the vehicle is information for a vehicle system including vehicle operation control of traveling, braking, or steering of the vehicle and determine whether the software update information is information for an information system when the software update information is not information for the vehicle system,

an information recording and management device that stores a list of IDs of software update information items, records the information and manages the update of the software update information when the determining portion determines that an ID of the acquired software update information is identical to an ID of the list of IDs and that accordingly the software update information acquired by communication with outside of the vehicle is the information for the vehicle system;

a transmitting device that transmits the software update information when it is determined that the software update information acquired by communication with outside of the vehicle is information for the information system; and

a second device including an information recording and management device that records the software update information transmitted by the transmitting device as information for the information system and manages the update of the software update information,

wherein the first device connects three networks including an information system network, a vehicle system network, and a vehicle external communication network, and

the second device is an information processing device including a navigation device that performs a vehicle route guidance.
