[0245] That is, the communication manager (720z1) in the first area signal processing device (170z1) can be connected to the communication manager (720) in the central signal processing device (170) through the third port (CTcz1) and to the communication manager (720z2) in the second area signal processing device (170z2) through the fourth port (CTdz1).

[0248] Meanwhile, the SDN controller (745) and switch manager (748) within the central signal processing unit (170) can transmit messages to the communication manager (720) regardless of the destination of the message.

[0249] Meanwhile, the SDN controller (745z1) and switch manager (748z1, 748z2) within the multiple area signal processing devices (170z1~170z2) can transmit a message to the communication manager (720z1, 720z2) regardless of the destination of the message.

[0250] Meanwhile, information such as the location of the network controller to operate in case of an anomaly or default, and network information access keys, can be stored in the SDN information table within each communication manager (720, 720z1, 720z2).

[0251] Figure 9c illustrates an example of an SDN information table.

[0252] Referring to the drawing, the SDN information table can be stored in each communication manager (720, 720z1, 720z2) within the central signal processing unit (170) and the plurality of area signal processing units (170z1~170z2).

[0260] Referring to the diagram, the echo request message may include a payload.

[0261] The echo request message can be transmitted from the switch manager (748z1~748z4) of each area signal processing unit (170z1~170z4) to the network controller (740) in the central signal processing unit (170).

[0262] The echo request message may include version information, type information, length information, ID information, processor usage information, and memory capacity information.

[0263] Figure 9f illustrates an echo response message.

[0264] Referring to the drawing, the echo response message may include type information.

[0265] Figure 9g illustrates an example of an echo response message of Figure 9f.

[0266] Referring to the drawing, the echo response message may include a payload.

[0267] The echo response message can be transmitted from the SD controller (745) in the network controller (740) in the central signal processing unit (170) to the switch manager (748z1~748z4) of each area signal processing unit (170z1~170z4).

[0268] The echo response message may include version information, type information, length information, ID information, next network controller information, and network information access key information.

[0269] Meanwhile, the following network controller information may include information about the selected candidate area signal processing device.

[0270] FIG. 10 is a flowchart illustrating an example of the operation of a vehicle control device according to an embodiment of the present disclosure.

[0271] Referring to the drawings, the switch manager (748z1~748z4) in the area signal processing device (170z1~170z4) in the vehicle control device (1000) according to the embodiment of the present disclosure transmits an echo request message (S1105).

[0272] In particular, the switch manager (748z1~748z4) within the plurality of area signal processing devices (170z1~170z4) can transmit an echo request message containing capacity information of the processor (175z1~175z4) and capacity information of the memory (925z1~925z4) to the central signal processing device (170).

[0273] Next, the SDN controller (745) in the network controller (740) in the central signal processing unit (170) receives an echo request message from each area signal processing unit (170z1~170z4) (S1110).

[0274] Meanwhile, the SDN controller (745) in the network controller (740) in the central signal processing unit (170) can extract information on the available capacity of the processor and the available capacity of the memory in the echo request message.

[0275] Meanwhile, the SDN controller (745) in the network controller (740) in the central signal processing unit (170) can determine whether there is one or more area signal processing units in which the processor's available capacity information exceeds a first threshold and the memory's available capacity information exceeds a second threshold (S1115).

[0276] At this time, the first reference value corresponds to the minimum available capacity of a processor for operating an SDN controller (745z) within a region signal processing device (170z), and the second reference value may correspond to the minimum available capacity of memory for operating an SDN controller (745z) within a region signal processing device (170z).

[0277] Meanwhile, the SDN controller (745) in the network controller (740) in the central signal processing unit (170) can determine whether there are two or more area signal processing units in which the memory capacity information exceeds the second threshold when there is one or more area signal processing units in which the processor capacity information exceeds the first threshold and the memory capacity information exceeds the second threshold (S1117).

[0278] Meanwhile, in step 1117 (S1117), the SDN controller (745) in the network controller (740) in the central signal processing unit (170) may select the area signal processing unit satisfying the condition as the signal processing unit where the next network controller is located, if there are not two or more area signal processing units where the processor's capacity information exceeds the first threshold and the memory's capacity information exceeds the second threshold, i.e., there is only one area signal processing unit (S1118).

[0279] Meanwhile, in step 1117 (S1117), the SDN controller (745) in the network controller (740) in the central signal processing unit (170) can calculate Equation 1 if there are two or more area signal processing units in which the processor's available capacity information exceeds the first threshold and the memory's available capacity information exceeds the second threshold (S1119).

[0280] [Mathematical Formula 1]

[0281] RST=(Zc-Cc) 2 +(Zm-Cm) 2

[0282] Here, Zc represents processor capacity information, Cc represents the first reference value, Zm represents memory capacity information, Cm represents the second reference value, and RSR may represent the calculation result.

[0283] Meanwhile, the SDN controller (745) in the network controller (740) in the central signal processing unit (170) can compare the calculation result (RST) of Equation 1 for each of the two or more area signal processing units (170z1~170z4) and select the area signal processing unit having the largest calculation result among them as the signal processing unit where the next network controller is located (S1121).

[0284] In step 1118 (S1118) and step 1121 (S1121), when the location of the next network controller is selected, the SDN controller (745) in the network controller (740) in the central signal processing unit (170) can set the corresponding area signal processing unit as the location of the next network controller (S1125).

[0285] Meanwhile, in step 1115 (S1115), if there is no area signal processing unit in which the processor (175) in the central signal processing unit (170) has processor capacity information exceeding the first threshold and memory capacity information exceeding the second threshold, the SDN controller (745) in the network controller (740) in the central signal processing unit (170) can calculate Equation 2 (S1127).

[0286] [Mathematical Formula 2]

[0287] RSB=(Zc-Cc)+(Zm-Cm)

[0288] Meanwhile, the SDN controller (745) in the network controller (740) in the central signal processing unit (170) can compare the calculation result (RSB) of Equation 2 for each area signal processing unit (170z1~170z4) and select the area signal processing unit having the largest calculation result among them as the signal processing unit where the next network controller is located (S1128).

[0289] In step 1128 (S1128), when the location of the next network controller is selected, the SDN controller (745) in the network controller (740) in the central signal processing unit (170) can set the location of the next network controller by adding an arbitrary constant (X) to the corresponding area signal processing unit (S1130).

[0290] At this time, any constant (X) is a value much larger than the number of the area signal processing device and can correspond to the resource shortage identifier in the fixed area (ARa) in the SDN information table of FIG. 9c.

[0291] Meanwhile, if the difference between the location of the next network controller and the location of the area signal processing unit corresponds to an arbitrary constant (X) at the time of operation of the next network controller, it is desirable to secure the available resources of the corresponding area signal processing unit.

[0292] Next, the SDN controller (745) in the network controller (740) in the central signal processing unit (170) can control the transmission of the next network controller's location information to all area signal processing units (170z1~170z4) by adding the next network controller's location information to the echo response message (S1135).

[0293] Next, the SDN controller (745) in the network controller (740) in the central signal processing unit (170) updates the SDN information table of FIG. 9c (S1138).

[0294] And, the processor (175) in the central signal processing unit (170) again performs step 1105 (S1105).

[0295] FIG. 11 is a flowchart illustrating another example of the operation of a vehicle control device according to an embodiment of the present disclosure.

[0296] Referring to the drawing, the communication manager (720) in the central signal processing unit (170) and the communication managers (720z1~720z4) in the area signal processing units (170z1~170z4) are connected to each other based on the SDN information table of FIG. 9c (S1205).

[0297] Next, the communication manager (720z1~720z4) within the area signal processing unit (170z1~170z4) is connected to the switch manager (748z1~748z4), and the communication manager (720) within the central signal processing unit (170) is connected to the SDN controller (745) within the network controller (740) (S1207).

[0298] Next, the switch manager (748z1~748z4) in each area signal processing unit (170z1~170z4) can send an echo request message to the communication manager (720) in the central signal processing unit (170) to the SDN controller (745) in the network controller (740) (S1209).

[0299] Next, the SDN controller (745) in the network controller (740) in the central signal processing unit (170) can select the next network controller based on available resource information and update the network information access key (S1211).

[0300] Next, the SDN controller (745) in the network controller (740) in the central signal processing unit (170) can send an echo response message to the communication manager (720z1~720z4) in all area signal processing units (170z1~170z4) (S1213).

[0301] At this time, the SDN controller (745) in the network controller (740) in the processor (175) in the central signal processing unit (170) can transmit an echo response message containing information about the selected candidate area signal processing unit (170z) and a network information access key to the selected first area signal processing unit (170z1).

[0302] Meanwhile, the communication manager (720z1~720z4) in the area signal processing unit (170z1~170z4) determines whether it receives an echo response message within a certain time from the network controller (740) in the processor (175) in the central signal processing unit (170) (S1215), and if applicable, updates the SDN information table of FIG. 9c (S1217).

[0303] Meanwhile, in step 1215 (S1215), the communication manager (720z1~720z4) within the area signal processing unit (170z1~170z4) may determine whether the difference between the location of the next network controller and the location within the network controller (740) within the processor (175) within the central signal processing unit (170) corresponds to 0 or any constant (X) if it does not receive an echo response message within a certain time (S1218), and if so, transmit an activation signal to the SDN controller (745z1) within the network controller (740z1) within the processor (175z1) within the first area signal processing unit (170z1) selected as the next network controller (S1220).

[0304] That is, the communication manager (720z1~720z4) within the area signal processing unit (170z1~170z4) can determine that the network controller (740) within the processor (175) is in an abnormal state if it does not receive an echo response message from the network controller (740) within the processor (175) within the central signal processing unit (170) within a certain period of time.

[0305] At this time, the communication manager (720z1) in the first area signal processing device (170z1) selected as the next network controller can transmit an activation signal to the SDN controller (745z1) in the network controller (740z1).

[0306] Meanwhile, based on the activation signal, the SDN controller (745z1) in the network controller (740z1) in the processor (175z1) in the first area signal processing device (170z1) can be activated.

[0307] Next, the SDN controller (745z1) in the network controller (740z1) in the processor (175z1) in the activated first area signal processing device (170z1) may request network settings for querying and modifying network information (S1222).

[0308] Next, the SDN controller (745z1) in the network controller (740z1) in the processor (175z1) in the first area signal processing device (170z1) determines whether the difference between the location of the next network controller and the location within corresponds to an arbitrary constant (X) (S1223), and if so, can transmit a resource acquisition request (S1225).

[0309] Meanwhile, in step 1218 (S1218), if the difference between the controller's position and my position does not correspond to 0 or any constant (X), at least one of the communication managers (720z1~720z4) in the area signal processing unit (170z1~170z4) determines whether the position of the next network controller is greater than any constant (X) (S1228), and if it is not, at least one of the communication managers (720z1~720z4) in the area signal processing unit (170z1~170z4) can set the position of the new network controller as the position of the next network controller (S1230).

[0310] Meanwhile, in step 1228 (S1228), if the position of the next network controller is greater than any constant (X), at least one of the communication managers (720z1~720z4) in the area signal processing device (170z1~170z4) can set the position of the new controller by subtracting any constant (X) from the position of the next network controller (S1232).

[0311] Next, the communication manager (720z1~720z4) within the area signal processing unit (170z1~170z4) updates the SDN information table and performs a connection with the new network controller (S1236).

[0312] Next, the communication manager (720z1~720z4) within the area signal processing device (170z1~170z4) can transmit an echo request message to the new network controller (740z1) as in step 1209 (S1209).

[0313] According to FIGS. 6 to 11, etc., a streaming application such as an OTT (Over-the-top media service) is executed in a processor (175) within a central signal processing unit (170), and data is transmitted to at least one area signal processing unit through an SDN controller (745) within a network controller (740) within the processor (175). In the event of a malfunction in the SDN controller (745), the SDN controller (745z) within the area signal processing unit, which is pre-configured as the next network controller, can be activated. Accordingly, if a malfunction occurs in the network controller, a replacement network controller in the candidate area operates to provide stable in-vehicle networking.

[0314] Similarly, a camera application for processing camera data, a lidar application for processing lidar data, a radar application for processing radar data, an ADAS application, or a vehicle autonomous driving application, etc., is executed in a processor (175) within a central signal processing unit (170), and data is transmitted to at least one area signal processing unit through an SDN controller (745) within a network controller (740) within the processor (175), and in the event of a failure of the SDN controller (745), the SDN controller (745z) within the area signal processing unit, which is pre-configured as the next network controller, can be activated. Accordingly, stable in-vehicle networking can be provided.

[0315] Although preferred embodiments of the present disclosure have been illustrated and described above, the present disclosure is not limited to the specific embodiments described above. Various modifications are possible by those skilled in the art without departing from the essence of the present disclosure as claimed in the claims, and such modifications should not be understood individually from the technical spirit or perspective of the present disclosure.
