Problems solved by technology

[0003] At present, the data loggers used by original equipment manufacturers (OEM) manufacturers are generally customized products produced by specialized data logger manufacturers, and are matched with the matching vehicles. Such data recorders The instrument can only be applied to the corresponding models produced by the corresponding car companies, and is not universally applicable, and since each model needs to be customized according to the data recording requirements, with the diversification of models and the increase in recording requirements, it needs to be based on Different car companies and different models carry out targeted development of equipment, resulting in increased development and customization costs, increased workload for sample control, increased development cycle, and increased development difficulty
[0004] In addition, before the above-mentioned custom-made recorder is used, it is necessary to pre-configure the parameters of the recorder and perform various settings in advance, so that the recorder can be installed on the vehicle for corresponding data collection and recording. When the data After the recorder is installed on the vehicle, parameter configuration and function setting can no longer be performed, and when the data recorded by the data recorder needs to be analyzed and used, the data recorder needs to be removed from the vehicle and connected to a personal computer The recorded data can be further used only by reading and parsing data on the Internet. The complexity of the operation is high and the flexibility is poor.
[0005] It can be seen that the existing data recorder for vehicle data recording has poor flexibility during development and use, and is not convenient for flexible adjustment and configuration for different vehicle models, and the cost is high, and the operation of the data is troublesome and cannot be adapted. Data recording requirements for various vehicle types

Embodiment 1

[0079] Embodiment 1 of the present invention provides a self-driving vehicle data recording system, its structure is as follows figure 1 As shown, it includes: data acquisition equipment 1 and user terminal 2; wherein, the structure of the data acquisition equipment can be found in figure 2 shown.

[0080] The data acquisition device includes at least two input ports and at least one output port; wherein:

[0081] At least one of the input ports is connected to the first communication network segment between the lower computer 5 and the vehicle 6 for obtaining driving data transmitted between the lower computer 5 and the vehicle 6;

[0082] At least one of the input ports is connected to the second communication network segment between the upper computer 4 and the lower computer 5, for obtaining the driving data transmitted between the upper computer 4 and the lower computer 5;

[0083] The output port is connected to the user terminal 2 for sending the acquired driving dat...

Embodiment 2

[0095] Embodiment 2 of the present invention provides an automatic driving vehicle data recording system, its structure is as follows figure 2 As shown, the difference from the data recording system provided by Embodiment 1 is that: a data conversion device 7 is connected between the upper computer 4 and the lower computer 5, and the upper computer 4 and the data conversion device 7 communicate in the first data format , communicate with the second data format between the lower computer 5 and the data conversion device 7;

[0096] The data conversion device 7 is used to convert the driving data in the first data format sent by the upper computer 4 into a second data format and then send it to the lower computer 5; at this time, the second communication network segment is the data conversion device 7 and the lower computer 5 Communication network segment between. The data acquisition device 1 is used to acquire the data port of the driving data transmitted between the upper com...

Embodiment 3

[0125] Embodiment 3 of the present invention provides a method for recording data of an automatic driving vehicle, the process of which is as follows Figure 4 shown, including the following steps:

[0126] Step S401: The data collection device is connected to the user terminal through at least one output port, receives an instruction sent by the user terminal according to the user's demand, and sets the data collection device according to the instruction.

[0127] The user can input the setting instruction required by the user through the user interface of the user terminal. After the user terminal obtains the setting instruction input by the user, it sends the instruction to the data acquisition device through the output port of the data acquisition device, and the data acquisition device performs settings according to the instruction, for example Set any one of the collected data content, data collection method, used port, communication network segment connected to the port...

Abstract

A data recording system and method for an autonomous vehicle and a data collection device are disclosed. The system includes the data collection device and a user terminal. The data collection deviceincludes at least two input ports and at least one output port. At least one input port is connected to a first communication network segment between a slave computer and a vehicle and is used for acquiring vehicle driving data transmitted between the slave computer and the vehicle. At least one input port is connected to a second communication network segment between a host computer and the slavecomputer and is used for acquiring vehicle driving data transmitted between the slave computer and the host computer. The output port is connected to the user terminal and used for sending the acquired vehicle driving data to the user terminal. The user terminal is used for sending an instruction for setting the data collection device according to user demands and storing the vehicle driving datato a database. Configuration and adjustment can be performed for different vehicle types to adapt to data recording demands of different vehicle types so that flexibility is high, the development cost is high and operation is simple.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to an automatic driving vehicle data recording system and method, and data acquisition equipment. Background technique [0002] For traditional fuel vehicles, most vehicle manufacturers will install data recorders during the test process to record the data generated by the vehicle under different working conditions, analyze the operating status of parts, and facilitate continuous monitoring and control of the vehicle status. optimized by the server software. For pure electric vehicles, in addition to installing a data recorder during testing, according to national regulations, each vehicle on the market must be equipped with a telematics box (T-Box) to collect bus data required by the regulations. [0003] At present, the data loggers used by original equipment manufacturers (OEM) manufacturers are generally customized products produced by specialized data logger manufact...
