Abstract

The system includes a vehicle and a remote centre, which manages traveling information of a plurality of vehicles. The remote centre transmits a message containing a collection condition to the in-vehicle communication set by wireless communication. The message has a header and a plurality of frames. The header identifies the in-vehicle communication set as the destination. Each frame has three fields. The Destination ECU is not used in the message from the remote centre to the communication set. A destination information conversion unit in the in-vehicle communication set fills in this field before sending the frame over the vehicle network. An information collection control device collects vehicle data from control devices connected to the vehicle network according to the collection condition and returns collected vehicle data to the remote centre.

Claims

1. A remote collection system comprising:

a vehicle including

a communication unit,

an information collection control device which has a predetermined network identification value,

a destination information conversion unit configured to convert destination information to the network identification value of the information collection control device connected to a vehicle network of the vehicle, the destination information being incorporated into a message including a collection condition of vehicle data by a specific value, and

a command execution unit of the information collection control device configured to receive through the vehicle network, using the converted destination information, the collection condition of vehicle data included in the message and configured to interpret and execute a command described by the collection condition of vehicle data included in the message; and

a remote device where the message including the collection condition of vehicle data is transmitted to the vehicle through the communication unit and vehicle data returned from the vehicle is collected through the communication unit,

wherein the information collection control device which has the network identification value converted by the destination information conversion unit is configured to collect vehicle data from one or a plurality of control devices connected to the vehicle network according to a collection condition designated based on the execution of the command by the command execution unit and is configured to return the collected vehicle data to the remote device through the communication unit.

2. The remote collection system according to claim 1, wherein

the vehicle includes a database in which types of vehicle data to be collected are associated with network identification values of the control devices to be an acquisition source of vehicle data in the vehicle network,

the collection condition designates the type of vehicle data, and

the information collection control device indexes a corresponding control device from the types of vehicle data based on the database and collects designated vehicle data.

3. The remote collection system according to claim 1, wherein

destination information incorporated into the message by the specific value is the network identification value which is not allocated to any of the control devices connected to the vehicle network.

4. The remote collection system according to claim 1, wherein

the message includes,

a header including destination information of the message from the remote device, and

a frame including the destination information of the collection condition of vehicle data included in the message,

the destination information of the collection condition of vehicle data included in the frame is incorporated by the specific value, and

the incorporated destination information is converted to the network identification value of the information collection control device through the destination information conversion unit.

5. The remote collection system according to claim 1, wherein

the vehicle network is a controller area network, and

the network identification value is an identifier in the controller area network.

6. The remote collection system according to claim 1, wherein

the remote device is a center which manages traveling information of a plurality of vehicles.

7. The remote collection system according to claim 1, wherein

the collection condition of vehicle data is designated by a script in which one or a plurality of commands are described.
