Abstract

A system for collecting vehicle data includes: at least one vehicle controller in a vehicle network configured to control driving of a vehicle; a server configured to monitor a load state of the vehicle network and request a data collection by adjusting a control parameter corresponding to a selected vehicle controller according to an available capacity in the vehicle network when any one of the at least one vehicle controller is selected; and a data collection device configured to request data corresponding to the control parameter according to a request of the server by determining an error range based on the load state of the vehicle network. The at least one vehicle controller detects the data corresponding to the control parameter and arranges and transmits the data corresponding to the control parameter based on the load state of the vehicle network and the error range.

First claim

What is claimed is:

1 . A system for collecting vehicle data, the system comprising:
at least one vehicle controller in a vehicle network configured to control driving of a vehicle; a server configured to monitor a load state of the vehicle network and request a data collection by adjusting a control parameter corresponding to a selected vehicle controller according to an available capacity in the vehicle network when any one of the at least one vehicle controller is selected; and a data collection device configured to request data corresponding to the control parameter according to a request of the server by determining an error range based on the load state of the vehicle network, wherein the at least one vehicle controller detects the data corresponding to the control parameter and arranges and transmits the data corresponding to the control parameter based on the load state of the vehicle network and the error range.

2 . The system of claim 1 , wherein the server includes a simulator configured to determine the available capacity in the vehicle network based on a difference between a load amount threshold for the vehicle network and an average network load amount and compare the available capacity with a size of a control parameter selected in response to the selected vehicle controller.

3 . The system of claim 2 , wherein the server further includes a script generation unit configured to generate a script including the selected control parameter when the size of the selected control parameter does not exceed the available capacity according to the comparison of the simulator.

4 . The system of claim 1 , wherein the data collection device includes a capacity analysis unit configured to determine the load state of the vehicle network in real-time or at every predetermined period and provide the determined load state to the server.

5 . The system of claim 1 , wherein the data collection device includes an error range determination unit configured to compare a difference between an average network load amount for the vehicle network and an actual network load amount of the vehicle network and determine an error range of the actual network load amount.

6 . The system of claim 1 , wherein the at least one vehicle controller includes:
a data detection unit configured to detect data corresponding to the control parameter by determining a control parameter included in the data collection request received from the data collection device; and a data allocation unit configured to separate the data detected by the data detection unit based on a control parameter unit and allocate data based on the error range for each data transmission period.

7 . The system of claim 6 , wherein the data allocation unit allocates sequentially the data separated based on the control parameter unit to a data allocation space of a data stream corresponding to each data transmission period based on a network load amount and an error range, and
when a size of data allocated in a certain period exceeds the data allocation space of a corresponding data stream, allocates firstly data corresponding to the remaining allocation space among unallocated data except data allocated secondly in a corresponding period.

8 . A method for collecting a vehicle data, the method comprising:
receiving, by a data collection device, a command script from a server including a control parameter selected according to an available capacity for a vehicle network connected to a vehicle controller for controlling driving of a vehicle; determining, by the data collection device, an error range according to a load state of the vehicle network in response to a request of the server; transmitting, by the data collection device, the command script received from the server and the error range to the vehicle controller; receiving, by the data collection device, data corresponding to the control parameter included in the command script from the vehicle controller according to the error range; and sending, by the data collection device, the data received from the vehicle controller to the server, wherein the data corresponding to control parameters are separated based on the control parameter and arranged for each period according to the load state of the vehicle network and the error range.

9 . The method of claim 8 , further comprising:
before the receiving of the command script from the server: determining, by the server, an available capacity of the vehicle network based on a difference between a load amount threshold for the vehicle network and an average network load amount; and generating, by the server, the command script including the selected control parameter when a size of the selected control parameter does not exceed the available capacity.

10 . The method of claim 8 , wherein the transmitting of the command script and the error range to the vehicle controller comprises:
comparing a difference between an average network load amount of the vehicle network and an actual network load amount of the vehicle network; and determining an error range of the actual network load amount.

11 . The method of claim 8 , further comprising:
before the receiving of the data corresponding to the control parameter: detecting, by the vehicle controller, data corresponding to the control parameter by determining control parameters included in the command script; separating, by the vehicle controller, the detected data based on a control parameter unit; and sequentially allocating, by the vehicle controller, the data separated based on the control parameter unit to a data allocation space of a data stream corresponding to each data transmission period depending on a network load amount and the error range.

12 . The method of claim 11 , wherein the sequential allocating of the data comprises:
when a size of data allocated in a certain period exceeds the data allocation space of a corresponding data stream, allocating firstly data corresponding to the remaining allocation space among unallocated data except data allocated secondly in a corresponding period.
