REMOTE VEHICLE DATA COLLECTION SYSTEM

BACKGROUND OF THE INVENTION

1. Field of the Invention

[0001] The present invention relates to a remote collection system which collects vehicle data remotely.

2. Description of Related Art

[0002] As this type of system, a system described in Japanese Patent Application Publication No.2006-283651 has been hitherto known. In this system, instruction items when transmitting vehicle data to a center are transmitted to a data processing unit of a vehicle diagnostic device mounted in a vehicle in advance. The instruction items include a data type to be diagnosed and a conditional expression for determining whether or not to transmit vehicle data. The data processing unit sends an instruction to each corresponding apparatus control electronic control unit (ECU) connected to an in-vehicle local area network (LAN) according to the received instruction items, and vehicle data from the apparatus control ECUs is stored in a data transmission buffer. Thereafter, vehicle data stored in the data transmission buffer is returned from the vehicle to the center regularly or according to a request from the center.

SUMMARY OF THE INVENTION

[0003] On the other hand, in the system described in the above-described document, it is necessary to transmit the instruction items from the center to the vehicle after designating destination information in the in-vehicle LAN corresponding to the data processing unit. In general, since the destination information in the in-vehicle LAN is different for each vehicle type, a case where the destination information of the instruction items in a plurality of vehicles to be managed by the center is unitarily managed has been considered. However, in the unitary management by the center, it is necessary to update the destination information each time a vehicle type to be managed is added.
[0004] This problem is already common, for example, for a case where a condition when collecting vehicle data is instructed directly from an external terminal to the vehicle without passing through the center, or the like, without being limited to a case where a condition when collecting vehicle data is instructed from the center to the vehicle.
[0005] The invention provides a remote collection system of vehicle data capable of accurately collecting vehicle data from the vehicle with remote communication.
[0006] A remote collection system according to an aspect of the invention includes 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 a 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 configured to interpret and execute a command described as the collection condition of vehicle data included in the message; and a predetermined location where the message including the collection condition of vehicle data is transmitted to the vehicle and vehicle data returned from the vehicle is collected. The information collection control device which has a network identification value converted by the destination information conversion unit collects vehicle data from one or a plurality of control devices connected to the vehicle network according to a collection condition designed based on the execution of the command by the command execution unit and returns the collected vehicle data to the predetermined location through the communication unit.
[0007] According to the above configuration, if the network identification value of the information collection control device is managed on a target vehicle side, the collection condition of vehicle data included in the message with the destination information converted is transmitted to the information collection control device. Then, vehicle data can be accurately collected from the vehicle through the information collection control device.
[0008] In the remote collection system of vehicle data, the collection condition may designate types of vehicle data, the target vehicle may include a database in which the 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, and the information collection control device may index a corresponding control device from the types of vehicle data based on the database and may collect designated vehicle data.
[0009] According to the above configuration, vehicle data of the type designated by the collection condition can be collected from the corresponding control device using the database provided in the target vehicle. That is, there is no need for unitarily managing information of each vehicle in the center described above.
[0010] In the remote collection system of vehicle data, destination information incorporated into the message by the specific value may be the network identification value which is not allocated to any of the control devices connected to the vehicle network.
[0011] According to the above configuration, even if the collection condition of vehicle data included in the message transmitted from the predetermined location is sent to the vehicle network without accompanying the conversion of the destination information, the sent collection condition of vehicle data is not transmitted to any of the control devices connected to the vehicle network. For this reason, the occurrence of problems, such as erroneous transmission of the collection condition of vehicle data to an unintended control device through the vehicle network is eliminated.

发明总结

[0004] 这个问题已经很常见了,例如,一个外部终端直接向车辆发送收集车辆数据的指示而没有经过中心,或者像中心向车辆发送收集车辆数据的指示的情况。

[0006] 根据本发明所述，一个远程采集系统包含一个车辆拥有一个通信单元，一个拥有预设定的网络识别码的信息采集控制设备，一个配置为将目标信息转换为连接在车载网络上的信息采集控制设备的网络识别码、将目标信息合并到消息中的目标信息转换单元，该消息包括一个由特定值表明的车辆数据采集条件，以及配置为解释和执行描述为该消息中包含的车辆数据收集条件的指令的指令执行单元；和一个包括所述数据被传送到车辆、所述车辆返回的车辆数据的采集状态的预设位置。拥有目标信息转换单元转换而来的网络识别码的信息采集控制设备，根据指令执行单元基于指令执行设计的采集条件，通过通信单元，从一个或多个连接到车辆网络的控制设备采集并返回车辆数据到预定的位置。

[0008] 在车辆数据的远程采集系统中,采集条件可能指定数据的类型,目标车辆可能包含一个拥有与不同数据类型相关联的车辆通讯网络中数据源的数据库，数据源即拥有网络识别码的控制设备, 信息采集控制装置可以根据该数据库从车辆数据类型中检索出相应的控制装置，并可以采集指定的车辆数据。

[0010] 在车辆数据的远程采集系统中，作为特定值并入消息的目标信息可以是不分配给连接在车辆网络中的任何控制设备的网络识别码。

[0012] 在车辆数据的远程采集系统,消息可能包含一个由消息中预设位置确定的目标信息的包头,和一个包含消息中采集条件里目标信息的帧,帧中采集条件里的目标信息可能被合并在特定值中,而且所述被合并的目标信息可以通过目标信息转换单元转换为信息采集控制装置的网络识别码。

[0014]在车辆数据远程采集系统中，车辆网络可以是控制器局域网络(CAN)，网络识别码可以是CAN-ID。

[0016]根据上述配置，可以在中心批量管理与中心相关的多个车辆的数据采集。在车辆数据远程采集系统中，车辆数据的采集条件可以由一个或多个描述命令的脚本来指定。
