Such vehicles have not changed much in the past for the purpose of transporting passengers, but they are significantly different from conventional ones in terms of the value of the vehicle and the indoor environment. In other words, although recent vehicles vary in price range and installation equipment, even if they are of the same type, there are many differences in price range and performance and convenience.

In addition, as the number of vehicles increases and the number of users increases, an increase in convenience is regarded as an essential requirement, frequent theft accidents are frequent, and a countermeasure is required. An immobilizer system developed and commercialized for this purpose is the immobilizer system.

The immobilizer system is a system in which the handle or the transmission is unlocked so that the vehicle can be used only when the IC is authenticated by the authentication key (FOB) with IC.

When the user goes near the vehicle with the authentication key, the immobilizer system recognizes this in the vehicle and automatically unlocks the car and switches to a state in which the car can be started. In addition, even when the user boarded and started, a start is made through a metal key of a separate key (a separate function in which the metal key portion and the FOB portion are integrated with each other) separate from the authentication key, or a lever I will hang it.

In other words, the immobilizer system prevents the vehicle from being stolen by preventing starting of the vehicle unless it is a unique genuine key of the vehicle. Information embedded in the transponder of the key at the time of starting the engine is transmitted through the antenna of the key cylinder The SmartRa unit determines whether the information of the key transmitted through the antenna is the same as the information input to the vehicle, and transmits the signal received from the transponder of the key to the smartra unit of the immobilizer system Only when the signals are the same, the engine controller (ECU) sends an OK sign indicating "may start".

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to data management required for starting permission of a vehicle immobilizer system, and relates to a method for checking whether or not information of a smart RAM unit required for an engine controller to permit start-up is proper.

The immobilizer system consists of a transponder and a Smartra unit installed inside the head of the ignition key.

In the process of manufacturing the engine controller, information of the smart la unit is stored in the vehicle memory. The present invention is a method of checking whether the smart la unit information is stored in the vehicle memory during the process of manufacturing the engine controller .

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram schematically showing an engine control unit and an immobilizer system.

1, a vehicle immobilizer system includes a transponder 10, a smart ray unit 20, an electronic control unit (ECU) 30, and the like.

The transponder 10 is installed in a starter key of the vehicle and includes a power supply unit, a data transmission / reception unit, and a control unit. The transponder 10 serves to provide an authentication code for driving the engine of the vehicle.

The power supply unit of the transponder 10 receives electromagnetic force induced by the coil of the antenna of the smart ray unit 20 to operate all the components of the transponder 10. [ That is, when the ignition key is turned on (IGN ON), the electric power of the vehicle is supplied to the smart ray unit 20, the electromagnetic force is induced in the coil of the antenna of the smart ray unit 20, do.

The data transmitting and receiving unit of the transponder 10 transmits and receives data to and from the antenna of the smart ray unit 20. The control unit receives the request signal and the random number for the unique identifier of the transponder 10 from the smart ray unit 20, Generates a random number and a unique identifier of the transponder (10) as a cipher value, and transmits the cipher value to the smart ray unit (20).

The smart ray unit 20 is installed in a starter key of the vehicle, and includes an antenna, a database, a random number generating unit, a control unit, and an authentication unit.

The antenna of the Smart La Unit 20 is provided with a coil for inducing an electromagnetic force using a power source supplied from a vehicle and transmitting and receiving data to and from the transponder 10. [

The unique identifier of the transponder 10 and the unique identifier of the smart ray unit 20 are stored in the database of the smart ray unit 20.

The random number generation unit of the SmartRa unit 20 generates a random number.

The control unit of the Smart La Unit 20 transmits a request signal and a random number to the unique identifier of the transponder 10 to the transponder 10 and receives from the transponder 10 the unique identifier of the transponder 10 and the random number And receives the encryption value generated by the encryption key.

The authentication unit of the smart ray unit 20 extracts and decrypts the unique identifier of the transponder 10 from the encryption value using the random number. The authentication unit compares the unique identifier of the decrypted transponder 10 with the unique identifier of the transponder 10 previously stored in the database to perform authentication.

The engine control unit (30) includes a memory unit (31) and a decryption unit (32).

In the memory unit 31 included in the engine control unit 30, necessary data is stored during the production process of the engine control unit 30. In the immobilizer type inspection method according to the present invention, the memory unit 31 stores type information on the immobilizer system. This will be described later.

The decryption unit 32 included in the engine control unit 30 decrypts encrypted data including type information related to the immobilizer system and restores the decrypted data. If the encrypted data is not used when the initial data relating to the immobilizer system is transmitted from the automation equipment, other users other than the person in charge of the immobilizer system can snoop the information on the immobilizer system, And transmits and receives the immobilizer system information.

2 is a diagram showing a case where the immobilizer system information is erroneously stored in the memory unit.

Referring to FIG. 2, an EEPROM is shown as an example of the memory unit 31. FIG. If the A information is stored in the EEPROM and the immobilizer system information includes information about the A, then the appropriate data is stored in the EEPROM.

However, if B information is stored in the EEPROM and the immobilizer system information includes information on A, erroneous data is stored in the EEPROM. In this case, the vehicle can not be started.

Therefore, in the immobilizer type inspection method according to the present invention, in order to confirm whether or not the immobilizer system information is properly stored, in the production process of the engine control unit 30, from the header file generated during booting of the vehicle software And checking whether the type information about the extracted immobilizer matches the type information about the immobilizer included in the encrypted data provided for the inspection. This will be described later.

FIG. 3 is a flowchart sequentially illustrating an existing immobilizer system information storing method.

Referring to FIG. 3, the vehicle production process can be broadly divided into a controller production line 10 and a vehicle assembly line 20, in which the information of the smart la unit is stored in the controller production line 10.

3, the smart production unit information is stored in the EEPROM in the controller production line 10, and the information is matched with the information of the actual smart unit, so that the start permission is performed.

However, as the type of the immobilizer system of the vehicle software increases, there arises a case where erroneous information is stored in the EEPROM in the controller production line 10 due to carelessness and misunderstanding of the operator. In this case, in the final process of the vehicle assembly line 10, there is a problem that the immobilizer module is not registered in the process of registering the key code and is unable to start.

In addition, there is a problem that erroneous information regarding the vehicle software in the engine control unit (ECU) is stored in the EEPROM so that startup is not permitted.

This leads to a problem of time loss and productivity deterioration.

4 is a flowchart sequentially illustrating an immobilizer type inspection method according to an embodiment of the present invention.

Referring to FIG. 4, in the method of inspecting an immobilizer type according to an embodiment of the present invention, when the immobilizer system manager inputs an immobilizer system type in an XML file in a compile process, This defined header file is automatically generated.

In the controller production line 10, the first type information for the immobilizer system extracted from the header file generated in the vehicle software booting process is stored in the memory unit 31 (for example, EEPROM).

Then, using the CAN (Controller Area Network) communication, encrypted data including second type information for the immobilizer system is received, and the decrypting unit 32 decrypts the encrypted data.

The decoded second type information is stored in the memory unit 31.

Then, the first type information and the second type information are read from the memory unit 31, and the first type information is compared with the second type information.

If the first type information matches the second type information, the memory unit 31 stores data for authenticating that the immobilizer system information is normal.

If the first type information and the second type information do not match, the second type information stored in the memory unit 31 is erased and the memory unit 31 stores data indicating that the immobilizer system information is abnormal . In the automation equipment, the process of inspecting the immobilizer system type is performed and displayed to the user, and the process of storing the second type information in the memory unit 31 is performed again.

The method for inspecting the immobilizer type according to the present invention checks whether or not the information matches the information of the immobilizer system or smart la unit of the vehicle software in the process of storing the immobilizer system information in the memory unit 31 in the process of the controller production line 10 To determine if the immobilizer type has been properly stored prior to shipment of the controller production.

The smart vehicle unit information is stored in the memory unit 31 before matching the type information stored in the memory unit 31 with the type information stored in the memory unit 31 before the immobilizer system type information is stored in the memory unit 31, Reliability and stability can be ensured.

The process of determining whether the type information of the immobilizer system to be stored in the memory unit 31 is appropriate may be determined in the process of the controller production line 10 instead of being confirmed in the final process of the vehicle assembly line 20 It is possible to prevent accidents caused by negligence, misunderstanding or error of the operator.

The conventional method has a weak point that the information stored in the memory unit 31 is not proper information until the vehicle assembly line 20 is confirmed. Thus, time loss and productivity deteriorated. The present invention has the effect of securing the reliability and stability of the immobilizer system, and the improved system has no additional cost and has the effect of preventing the temporal loss.

The steps of a method or algorithm described in connection with the embodiments of the invention may be embodied directly in hardware, in a software module executed by a processor, or in a combination of the two. The software module may reside in RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, a hard disk, a removable disk, a CD-ROM, or any other form of recording medium known in the art. An exemplary recording medium is coupled to a processor, which is capable of reading information from, and writing information to, the storage medium. Alternatively, the recording medium may be integral with the processor. The processor and the recording medium may reside in an application specific integrated circuit (ASIC). The ASIC may reside within the user terminal. Alternatively, the processor and the recording medium may reside as discrete components in a user terminal.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
