Description

Method and system for recording and managing vehicle generation data {METHOD AND SYSTEM FOR RECODING AND MANAGING VEHICLE GENERATED DATA}

The present invention relates to a method and system for recording and managing vehicle-generated data, and more specifically, to an apparatus and method for securing driving data of an autonomous vehicle by transmitting autonomous driving data of the vehicle through TCP/IP communication. .

The information described in this section simply provides background information on the present invention and does not constitute prior art.

In general, an event data recorder (EDR) is configured to detect an accident or the like and store information about a driving state of a vehicle or an operation by a driver within a predetermined time before or after the point in time. At least several parameters including speed, seat belt status, and airbag deployment status are stored so that they can be restored during forensic investigation.

As the application of Advanced Driver Assistance Systems (ADAS) or autonomous driving functions expands, the causes of accidents are shifting from the driver to the vehicle itself. In addition to 　EDR data recorded by existing event data recorders, the collection of additional data on the operation status of ADAS or 　autonomous driving functions and how the vehicle system judges sensor inputs can be useful in properly identifying the cause of such an accident. .

Data generated, recorded, and stored in vehicles, including EDR data, can be used in a variety of ways, from vehicle-related services (insurance, maintenance, used car trading, rental/sales, etc.) to marketing purposes and research purposes (traffic analysis, autonomous driving, etc.). can For example, vehicle manufacturers and the like want to use vehicle data to verify and improve the functions of various ECUs, sensors, and other components mounted in vehicles. In addition, in the insurance industry, so-called 'Usage Base Insurance (UBI)' is being attempted to calculate an insurance premium suitable for the risk caused by the driver's driving tendency.

As autonomous driving functions are applied and generalized, discussions on various standards are actively underway in relation to driving data that needs to be analyzed, communication specifications and communication methods of driving data, etc.

As information and communication technology develops, such vehicle generated data can be collected in various forms in a data server on a network and can be provided to various service providers. Some of the information that can be collected on the data server may be sensitive information in terms of personal privacy. Since the operators had the real control over and the right to sell personal information in these data servers, individuals had to bear a lot of risk.

Moreover, as legislation on personal information protection such as the General Data Protection Regulation (GDPR) in Europe is enacted, it is necessary to introduce a system that can efficiently collect and utilize vehicle-generated data within the framework of these laws. It is required.
