Abstract

A data collection device collects vehicle data related to a vehicle through different types of communication interfaces. The data collection device includes: a layout converter converting the vehicle data, which is provided by a data providing device and has a signal layout corresponding to one of the communication interfaces, into a common signal layout; a data converter converting the vehicle data, which is converted to have the common signal layout corresponding to the one of the communication interfaces according to a corresponding communication protocol, into data having a common format; a first connector through which the data converter acquires the vehicle data after the vehicle data is converted into the common signal layout by the layout converter; and a communication circuit transmitting the vehicle data, which is converted into the data having the common format by the data converter, to a server.

First claim

What is claimed is:

1 . A data collection device collecting vehicle data related to a vehicle through different types of communication interfaces and transmitting the collected vehicle data to a server, the data collection device comprising:
a layout converter converting the vehicle data, which is provided by a data providing device and has a signal layout corresponding to one of the communication interfaces, into a common signal layout; a data converter converting the vehicle data, which is converted to have the common signal layout corresponding to the one of the communication interfaces according to a corresponding communication protocol, into data having a common format; a first connector through which the data converter acquires the vehicle data after the vehicle data is converted into the common signal layout by the layout converter; and a communication circuit transmitting the vehicle data, which is converted into the data having the common format by the data converter, to the server, wherein the layout converter includes:
a common connector connected to the first connector through which the data converter acquires the vehicle data;
a providing end connector connected to a second connector of the data providing device, the data providing device providing the vehicle data that has the signal layout corresponding to the one of the communication interfaces; and
a cable connecting the common connector with the providing end connector to convert the signal layout of the providing end connector to the common signal layout of the common connector,
the vehicle data having the common signal layout includes an interface identifier indicating a type of the one of the communication interfaces, and the common connector includes:
multiple first pins used to specify the interface identifier indicating the type of the one of the communication interfaces; and
multiple second pins used to transmit the vehicle data.

2 . The data collection device according to claim 1 , wherein
each of the data converter and the communication circuit is supplied with a power from the data providing device through the cable.

3 . The data collection device according to claim 2 , wherein
a plurality of the layout converters are provided corresponding to the different types of communication interfaces, and when the plurality of the layout converters connect, via multiple cables, respective second connectors of the data providing device with respective first connectors through which the data converter acquires the vehicle data in accordance with respective different types of communication interfaces, each of the data converter and the communication circuit is supplied with the power from the data providing device through one of the multiple cables.

4 . The data collection device according to claim 1 , wherein
the data converter converts the vehicle data having the common signal layout into the data having the common format based on the interface identifier.

5 . The data collection device according to claim 1 , wherein,
when multiple signals from the different types of communication interfaces are same as one another, the multiple signals from the different types of communication interfaces are converted to a single signal having the common signal layout.

6 . A data collection system collecting vehicle data related to a vehicle through different types of communication interfaces and transmitting the collected vehicle data to a server, the data collection system comprising:
a data providing device; and a data collection device, wherein the data providing device includes:
a gateway transferring the vehicle data acquired from a network of a vehicle; and
a providing device connector providing the vehicle data, which is transferred from the gateway, in a signal layout corresponding to one of the communication interfaces,
the data collection device includes:
a layout converter converting the signal layout of the vehicle data, which is provided by the data providing device, into a common signal layout;
a data converter converting the vehicle data, which is converted to have the common signal layout corresponding to the one of the communication interfaces according to a corresponding communication protocol, into data having a common format;
a data collection connector through which the data converter acquires the vehicle data after the vehicle data is converted into the common signal layout by the layout converter; and
a communication circuit transmitting the vehicle data, which is converted into the data having the common format by the data converter, to the server,
the layout converter includes:
a common connector connected to the data collection connector through which the data converter acquires the vehicle data;
a providing end connector connected to the providing device connector of the data providing device; and
a cable connecting the common connector with the providing end connector to convert the signal layout of the providing end connector to the common signal layout of the common connector,
the vehicle data having the common signal layout includes an interface identifier indicating a type of the one of the communication interfaces, and the common connector includes:
multiple first pins used to specify the interface identifier indicating the type of the one of the communication interfaces; and
multiple second pins used to transmit the vehicle data.

7 . The data collection system according to claim 6 , wherein
the data providing device uses at least one of onboard diagnosis second generation (OBD2) or fleet management system (FMS) as the one of the communication interfaces of the vehicle data when transferring the vehicle data using the gateway.

8 . The data collection system according to claim 6 , wherein
the data providing device further includes an additional providing device connector that directly provides the vehicle data from the network of the vehicle, instead of providing the vehicle data through the gateway.

9 . A data collection method executed by at least one processor equipped to a vehicle, the data collection method collecting vehicle data related to a vehicle through different types of communication interfaces, the data collection method comprising:
converting, by a layout converter, the vehicle data, which is provided by a data providing device and has a signal layout corresponding to one of the communication interfaces, into a common signal layout; acquiring, through a first connector, the vehicle data after the vehicle data is converted into the common signal layout; converting, by a data converter, the vehicle data, which is converted to have the common signal layout corresponding to the one of the communication interfaces according to a corresponding communication protocol, into data having a common format; and transmitting, by a communication circuit, the vehicle data, which is converted into the data having the common format, to a server located outside of the vehicle, wherein the layout converter includes:
a common connector connected to the first connector through which the data converter acquires the vehicle data;
a providing end connector connected to a second connector of the data providing device, the data providing device providing the vehicle data that has the signal layout corresponding to the one of the communication interfaces; and
a cable connecting the common connector with the providing end connector to convert the signal layout of the providing end connector to the common signal layout of the common connector,
