Description

Method and apparatus for providing a code for extracting signals used in a vehicle controller {METHOD AND APPARATUS FOR PROVIDING CODE TO EXTRACT SIGNAL USED BY ELECTIRONIC CONTROLLER UNIT OF VEHICLE}

This disclosure relates to a method and apparatus for providing code for extracting signals used in a vehicle controller.

Recently, various researches have been actively conducted to electrically control various devices installed inside a vehicle to improve driving convenience and driving safety for vehicle drivers.

For electrical control of various devices such as the engine, transmission, brakes, and airbags inside the vehicle, a controller (Electronic Control Unit, ECU) may be provided to control each device. Vehicle network communication, such as CAN (Controller Area Network) communication, may be used to transmit and receive data between these controllers.

In general, CAN communication is provided with a database file that describes various information about the interior of the vehicle, such as signals used for communication and information about each controller. When raw data is transmitted through a bus connected to the controller, the controller can extract signals used in the controller from the raw data using a database file, and use the extracted signals to control each device. In order to extract signals used in the controller, a decoder developed by a controller software development company may be installed in each controller.

However, database files are in text form and may be vulnerable to security. Accordingly, when the entire database file is distributed, there is a possibility that other information in addition to the information used by each controller may be disclosed and utilized by other controllers.

Additionally, since database files are provided to software development companies to develop decoders suitable for each controller of various vehicles, there is a problem that important information in the database files is disclosed.

Accordingly, a method for providing a code for extracting signals used in a vehicle controller is required to increase the security of important information of a vehicle by minimizing unnecessary provision of database files.

These database files can be used to create at least one function for extracting signals used in each controller. Furthermore, the server 100 may obtain information in advance about signals used in a plurality of vehicles and a plurality of controllers provided in each vehicle.

Specifically, the server 100 uses a function creation tool 600 configured to receive identification information from the controller 10 and generate at least one function for extracting a signal used in the controller using the identification information as input.

For encryption, various encryption methods, such as an encryption method using an encryption key and a decryption key, can be used.

The controller 10 receiving this calls and executes at least one decoding function to extract the signal used in the controller 10 from the shared library file 130 to extract the signal from the raw data transmitted through the bus 11. can be extracted and the functions used in the controller 10 can be performed using the extracted signal.

In this way, the present disclosure can improve the security of important information of a vehicle by minimizing unnecessary provision of database files. Additionally, since each controller extracts and uses only the signals used in each controller, the possibility of signals used in each controller being used in other controllers is minimized, thereby preventing control errors and enhancing security.

In various embodiments, when the database file is updated and the updated database file is provided, the server 100 may update the shared library file using the updated database file and transmit the updated shared library file to the controller 10. . Accordingly, in the past, when updating a database file, an updated database file is provided to the controller software development company, the controller software development company updates the decoder using the updated database file, and the updated decoder is installed in each controller. Fast response is possible compared to a series of processes.
