[0139] The first virtual machine (820) can execute an operating system (822), a container runtime (824) on the operating system (822), and containers (827, 829) on the container runtime (824).

[0140] The second virtual machine (820) may be a virtual machine corresponding to ASIL A or ASIL B, where the sum of severity, exposure, and controllability is 7 or 8 in the automotive safety integrity level (ASIL).

[0141] The second virtual machine (820) can execute an operating system (832), a container runtime (834) on the operating system (832), and containers (837, 839) on the container runtime (834).

[0142] The third virtual machine (840) may be a virtual machine corresponding to ASIL C or ASIL D, in which the sum of severity, exposure, and controllability is 9 or 10 in the automotive safety integrity level (ASIL).

[0143] Meanwhile, ASIL D can correspond to the grade that requires the highest safety level.

[0144] The third virtual machine (840) can run a safety operating system (842) and an application (845) on the operating system (842).

[0145] Meanwhile, the third virtual machine (840) may also execute a safety operating system (842), a container runtime (844) on the safety operating system (842), and a container (847) on the container runtime (844).

[0146] Meanwhile, unlike the drawing, the third virtual machine (840) can also be executed through a separate core rather than the processor (175). This will be described later with reference to FIG. 5b.

[0147] FIG. 5b illustrates another example of a vehicle display device according to an embodiment of the present disclosure.

[0148] Referring to the drawings, a vehicle display device (800b) according to an embodiment of the present disclosure includes a signal processing device (170a1, 170a2) and a plurality of area signal processing devices (170Z1 to 170Z4).

[0149] The vehicle display device (800b) of FIG. 5b is similar to the vehicle display device (800a) of FIG. 5a, but the signal processing device (170a1) has some differences from the signal processing device (170a1) of FIG. 5a.

[0150] To describe the difference, the signal processing device (170a1) may include a processor (175) and a second processor (177).

[0151] The processor (175) within the signal processing unit (170a1) executes a hypervisor (505), and executes first and second virtual machines (820 to 830) on the hypervisor (505) according to the automotive safety integrity level (Automotive SIL; ASIL).

[0152] The first virtual machine (820) can execute an operating system (822), a container runtime (824) on the operating system (822), and containers (827, 829) on the container runtime (824).

[0153] The second virtual machine (820) can execute an operating system (832), a container runtime (834) on the operating system (832), and containers (837, 839) on the container runtime (834).

[0154] Meanwhile, the second processor (177) within the signal processing device (170a1) can execute a third virtual machine (840).

[0155] The third virtual machine (840) can execute a safety operating system (842), an auto-execution (845) on the operating system (842), and an application (845) on the auto-execution (845). That is, unlike FIG. 5A, an auto-execution (846) on the operating system (842) can be executed.

[0156] Meanwhile, the third virtual machine (840) may, similarly to FIG. 5a, execute a safety operating system (842), a container runtime (844) on the safety operating system (842), and a container (847) on the container runtime (844).

[0157] Meanwhile, the third virtual machine (840) requiring a high level of security is preferably executed on a second processor (177), which is a different core or different processor, unlike the first and second virtual machines (820 to 830).

[0158] Meanwhile, in the signal processing devices (170a1, 170a2) of FIGS. 5a and 5b, when the first signal processing device (170a) malfunctions, the second signal processing device (170a2), which is a backup device, can operate.

[0159] Alternatively, it is also possible for the signal processing devices (170a1, 170a2) to operate simultaneously, with the first signal processing device (170a) operating as the main device and the second signal processing device (170a2) operating as the sub device. This will be described with reference to FIGS. 5c and 5d.

[0160] FIG. 5c illustrates another example of a vehicle display device according to an embodiment of the present disclosure.

[0161] Referring to the drawings, a vehicle display device (800c) according to an embodiment of the present disclosure includes a signal processing device (170a1, 170a2) and a plurality of area signal processing devices (170Z1 to 170Z4).

[0162] Meanwhile, in the drawing, two signal processing devices (170a1, 170a2) are exemplified, but this is for backup purposes, etc., and one is also possible.

[0163] Meanwhile, the signal processing device (170a1, 170a2) may also be named an HPC (High Performance Computing) signal processing device.

[0164] Multiple area signal processing devices (170Z1 to 170Z4) are arranged in each area (Z1 to Z4) and can transmit sensor data to signal processing devices (170a1, 170a2).

[0165] The signal processing device (170a1, 170a2) receives data via a wire from multiple area signal processing devices (170Z1 to 170Z4) or a communication device (120).

[0166] In the drawing, data is exchanged based on wired communication between a signal processing device (170a1, 170a2) and multiple area signal processing devices (170Z1 to 170Z4), and the signal processing device (170a1, 170a2) and the server (400) exchange data based on wireless communication. However, data may be exchanged based on wireless communication between a communication device (120) and a server (400), and the signal processing device (170a1, 170a2) and the communication device (120) may exchange data based on wired communication.

[0167] Meanwhile, data received by the signal processing device (170a1, 170a2) may include camera data or sensor data.

[0168] Meanwhile, among the signal processing devices (170a1, 170a2), the processor (175) in the first signal processing device (170a1) can execute a hypervisor (505) and execute a safety virtualization machine (860) and a non-safety virtualization machine (870) on the hypervisor (505).

[0169] Meanwhile, among the signal processing devices (170a1, 170a2), the processor (175b) in the second signal processing device (170a2) executes the hypervisor (505b) and can execute only the safety virtualization machine (880) on the hypervisor (505).

[0170] In this way, since the processing for safety is separated between the first signal processing device (170a1) and the second signal processing device (170a2), it is possible to improve stability and processing speed.

[0171] Meanwhile, high-speed network communication can be performed between the first signal processing device (170a1) and the second signal processing device (170a2).

[0172] FIG. 5d illustrates another example of a vehicle display device according to an embodiment of the present disclosure.

[0173] Referring to the drawings, a vehicle display device (800d) according to an embodiment of the present disclosure includes a signal processing device (170a1, 170a2) and a plurality of area signal processing devices (170Z1 to 170Z4).

[0174] The vehicle display device (800d) of FIG. 5d is similar to the vehicle display device (800c) of FIG. 5c, but the second signal processing device (170a2) has some differences from the second signal processing device (170a2) of FIG. 5c.

[0175] The processor (175b) in the second signal processing device (170a2) of FIG. 5d executes a hypervisor (505b) and can execute a safety virtualization machine (880) and a non-safety virtualization machine (890) on the hypervisor (505).

[0176] That is, unlike FIG. 5c, the difference is that the processor (175b) within the second signal processing device (170a2) further executes a non-safety virtualization machine (890).

[0177] In this way, since the processing for safety and non-safety is separated into the first signal processing device (170a1) and the second signal processing device (170a2), it is possible to improve stability and processing speed.

[0178] FIG. 6 is an example of a block diagram of a vehicle display device according to an embodiment of the present disclosure.

[0179] Referring to the drawings, a vehicle display device (900) according to an embodiment of the present disclosure includes a signal processing device (170) and at least one display.

[0180] In the drawing, at least one display is illustrated, a cluster display (180a) and an AVN display (180b).

[0181] Meanwhile, the vehicle display device (900) may further include a plurality of area signal processing devices (170Z1 to 170Z4).

[0182] The signal processing device (170) at this time is a high-performance centralized signal processing and control device having multiple CPUs (175), GPUs (178), NPUs (179), etc., and may be called an HPC (High Performance Computing) signal processing device or a central signal processing device.

[0183] A plurality of area signal processing devices (170Z1 to 170Z4) and a signal processing device (170) are connected by wired cables (CB1 to CB4).

[0184] Meanwhile, multiple area signal processing devices (170Z1 to 170Z4) can be connected to each other with wired cables (CBa to CBd).

[0185] The wired cable (CBa~CBd) at this time may include a CAN communication cable, an Ethernet communication cable, or a PCI Express cable.

[0186] Meanwhile, a signal processing device (170) according to an embodiment of the present disclosure may be equipped with at least one processor (175, 178, 177) and a large-capacity storage device (925).

[0187] For example, a signal processing device (170) according to an embodiment of the present disclosure may include a central processor (175, 177), a graphics processor (178), and a neural processor (179).

[0188] Meanwhile, sensor data may be transmitted from at least one of the multiple area signal processing devices (170Z1 to 170Z4) to the signal processing device (170). In particular, the sensor data may be stored in a storage device (925) within the signal processing device (170).

[0189] The sensor data at this time may include at least one of camera data, lidar data, radar data, vehicle direction data, vehicle location data (GPS data), vehicle angle data, vehicle speed data, vehicle acceleration data, vehicle inclination data, vehicle forward / backward data, battery data, fuel data, tire data, vehicle lamp data, vehicle interior temperature data, and vehicle interior humidity data.

[0190] In the drawing, it is exemplified that camera data from a camera (195a) and lidar data from a lidar sensor (196) are input to a first area signal processing device (170Z1), and the camera data and lidar data are transmitted to a signal processing device (170) via a second area signal processing device (170Z2), a third area signal processing device (170Z3), etc.

[0191] Meanwhile, since the data read speed or write speed to the storage device (925) is faster than the network speed when sensor data is transmitted from at least one of the plurality of area signal processing devices (170Z1 to 170Z4) to the signal processing device (170), it is preferable that multi-path routing be performed so that a network bottleneck does not occur.

[0192] To this end, the signal processing device (170) according to the embodiment of the present disclosure can perform multi-path routing based on a Software Defined Network (SDN). Accordingly, a stable network environment can be secured when reading or writing data from the storage device (925). Furthermore, since data can be transmitted to the storage device (925) using multiple paths, the network configuration can be dynamically changed to transmit data.

[0193] Data communication between a plurality of area signal processing devices (170Z1 to 170Z4) and a signal processing device (170) in a vehicle display device (900) according to an embodiment of the present disclosure is preferably Peripheral Component Interconnect Express communication for high-bandwidth, low-latency communication.

[0194] FIG. 7 is another example of a block diagram of a vehicle display device according to an embodiment of the present disclosure.

[0195] Referring to the drawings, a vehicle display device (900) according to an embodiment of the present disclosure includes a central signal processing device (170) and at least one display.

[0196] Meanwhile, the vehicle display device (900) may further include a plurality of area signal processing devices (170Z1 to 170Z4).

[0197] A plurality of area signal processing devices (170Z1 to 170Z4) can receive sensor data from a sensor device or output a driving signal for driving an actuator.

[0198] Meanwhile, in order to perform high-speed communication and stable communication between the central signal processing unit (170) and multiple area signal processing units (170Z1 to 170Z4), in the present disclosure, common middleware is executed on the operating system.

[0199] For example, the common middleware may be a middleware based on the Vehicle Signal Specification (VSS).

[0200] A central signal processing device (170) according to one embodiment of the present disclosure comprises hardware (905) such as a processor (175), and the processor (175) executes an operating system (911 of FIG. 8b), executes a vehicle signal specification (VSS)-based middleware (920) on the operating system (911), and executes an application (932, 934) on the vehicle signal specification (VSS)-based middleware (920).

[0201] Meanwhile, a plurality of area signal processing devices (170Z1 to 170Z4) according to one embodiment of the present disclosure each have hardware (905Z1 to 905Z4) such as a processor (175Z1 to 170Z4), and each processor (175Z1 to 170Z4) executes a respective operating system, executes a middleware (920Z1 to 920Z4) based on a vehicle signal specification (VSS) on each operating system, and executes software (920Z1 to 920Z4) such as an application on each middleware (920Z1 to 920Z4) based on a vehicle signal specification (VSS).

[0202] Meanwhile, in one embodiment of the present disclosure, a processor (175) within a central signal processing unit (170) controls a message to be received or transmitted to a message interface (920Z1 to 920Z4) based on a vehicle signal specification (VSS) within a plurality of area signal processing units (170Z1 to 170Z4) using a message interface (920) based on a vehicle signal specification (VSS). Accordingly, high-speed and stable communication can be performed between the plurality of signal processing units.

[0203] In particular, on the other hand, in one embodiment of the present disclosure, the processor (175) within the central signal processing unit (170) uses a vehicle signal specification (VSS)-based message interface (920) to control, when communicating with an adjacent second signal processing unit (170Z1), to receive or transmit a message to a second vehicle signal specification (VSS)-based message interface (920) within the second signal processing unit (170Z1) using the vehicle signal specification (VSS)-based message interface (920). Accordingly, high-speed communication and stable communication can be performed between a plurality of signal processing units.

[0204] Meanwhile, the processor (175) within the central signal processing unit (170) can control the reception or transmission of a message using a message interface (920) based on the vehicle signal specification (VSS) when communicating with a second signal processing unit (170Z1) having a different operating system. Accordingly, high-speed and stable communication can be performed between multiple signal processing units having different operating systems.

[0205] Meanwhile, the processor (175) within the central signal processing unit (170) can execute an application (934) for controlling an IVI display (180b) or an application (932) for vehicle driving assistance on a middleware (920) based on a vehicle signal specification (VSS). Accordingly, each application (932, 934) can be stably executed.

[0206] Meanwhile, each processor (175Z1 to 170Z4) within a plurality of area signal processing devices (170Z1 to 170Z4) according to one embodiment of the present disclosure controls to receive or transmit a message to a vehicle signal specification (VSS)-based message interface (920) within a central signal processing device (170) using a vehicle signal specification (VSS)-based message interface (920Z1 to 920Z4). Accordingly, high-speed and stable communication can be performed between the plurality of signal processing devices.

[0207] Meanwhile, multiple area signal processing devices (170Z1 to 170Z4) can perform CAN communication with a sensor device or actuator.

[0208] Meanwhile, Ethernet communication or PCIe communication can be performed between multiple area signal processing devices (170Z1 to 170Z4) and the central signal processing device (170).

[0209] Figures 8a to 18b are drawings referred to in the description of Figure 6 or Figure 7.

[0210] FIG. 8a is an example of an operation description of a processor in the area signal processing device of FIG. 7.

[0211] Referring to the drawing, a processor (175Z) within a domain signal processing device (170Z) can receive or transmit a CAN message from a CAN interface (812) for CAN communication with a sensor device or actuator.

[0212] Meanwhile, the processor (175Z) within the area signal processing unit (170Z) can receive or transmit an Ethernet message from an Ethernet interface (814) for communication with the central signal processing unit (170).

[0213] Meanwhile, a processor (175Z) within a domain signal processing device (170Z) may execute a real-time operating system (RTOS) (910Z), execute a vehicle signal specification (VSS)-based middleware (920Z) on the operating system (910Z), and execute an application (931, 933, 935) on the vehicle signal specification (VSS)-based middleware (920Z).

[0214] The processor (175Z) within the area signal processing device (170Z) can further execute a data distribution service (DDS) (921) or a network (923) on the operating system (910Z). Accordingly, high computing performance can be guaranteed during data processing.

[0215] Meanwhile, since each of the multiple area signal processing devices (170Z1 to 170Z4) executes a common vehicle signal specification (VSS)-based middleware (920Z), high-speed and stable communication can be performed between the multiple area signal processing devices (170Z1 to 170Z4).

[0216] Meanwhile, a processor (175Z) within a domain signal processing device (170Z) may execute a real-time-based operating system (910Z), execute a message interface (920Z), which is a middleware based on a vehicle signal specification (VSS), on the operating system (910Z), and execute applications (931, 933, 935) on the message interface (920Z) based on a vehicle signal specification (VSS).

[0217] Meanwhile, since each of the plurality of area signal processing devices (170Z1 to 170Z4) executes a message interface (920Z) based on a common vehicle signal specification (VSS), high-speed and stable communication can be performed between the plurality of area signal processing devices (170Z1 to 170Z4).

[0218] FIG. 8b is an example of an operation description of a processor within the central signal processing unit of FIG. 7.

[0219] Referring to the drawing, a processor (175) within a central signal processing unit (170) can receive an Ethernet message from an Ethernet interface (824) for communication with a plurality of area signal processing units (170Z1 to 170Z4) or transmit an Ethernet message.

[0220] Meanwhile, the processor (175) in the central signal processing unit (170) can receive a PCIe message from a PCIe interface (826) for communication with a plurality of area signal processing units (170Z1 to 170Z4) or a memory (140) or a display (180) or a communication unit (120) or transmit a PCIe message.

[0221] Meanwhile, the processor (175) within the central signal processing unit (170) executes an operating system, executes a vehicle signal specification (VSS)-based middleware (920) on the operating system, and executes an application (932, 936, 938) on the vehicle signal specification (VSS)-based middleware (920).

[0222] In particular, the processor (175) can execute an application (936) for controlling a display (180) or an application (932) for vehicle driving assistance on a vehicle signal specification (VSS)-based middleware (920). Accordingly, the application can be stably executed.

[0223] At this time, the operating system may include a real-time operating system (RTOS) (911), Linux (912), or Android (914).

[0224] Meanwhile, the central signal processing unit (170) may be a higher-performance computing unit than the plurality of area signal processing units (170Z1 to 170Z4), and the operating system of the central signal processing unit (170) may be different from the operating systems of the plurality of area signal processing units (170Z1 to 170Z4).

[0225] Meanwhile, the processor (175) within the central signal processing unit (170) can further execute a Data Distribution Service (DDS) (924) or a Scalable Service-Oriented Middleware over IP (SOM / IP) on the operating system. Accordingly, high computing performance can be guaranteed during data processing.

[0226] Meanwhile, the central signal processing unit (170) executes a common vehicle signal specification (VSS)-based middleware (920) that is identical to the plurality of area signal processing units (170Z1 to 170Z4), so that high-speed and stable communication can be performed between the central signal processing unit (170) and the plurality of area signal processing units (170Z1 to 170Z4).

[0227] In particular, since the central signal processing unit (170) and the first area signal processing unit (170Z1) execute a common vehicle signal specification (VSS)-based middleware, high-speed and stable communication can be performed between the central signal processing unit (170) and the first area signal processing unit (170Z1).

[0228] Meanwhile, the processor (175) within the central signal processing unit (170) executes an operating system, executes a message interface (920), which is a middleware based on a vehicle signal specification (VSS), on the operating system, and executes an application (932, 936, 938) on the message interface (920) based on a vehicle signal specification (VSS).

[0229] Meanwhile, since the central signal processing unit (170) and each of the plurality of area signal processing units (170Z1 to 170Z4) execute a message interface based on a common vehicle signal specification (VSS), high-speed and stable communication can be performed between the central signal processing unit (170) and the plurality of area signal processing units (170Z1 to 170Z4).

[0230] In particular, since the central signal processing unit (170) and the first area signal processing unit (170Z1) execute a common vehicle signal specification (VSS)-based message interface, high-speed and stable communication can be performed between the central signal processing unit (170) and the first area signal processing unit (170Z1).

[0231] Figure 9a is a drawing illustrating an example of the structure of vehicle data.

[0232] Referring to the drawing, sensor data, actuator data, etc. within the vehicle can be expressed as leaves under the tree structure of the drawing.

[0233] When transmitting signals within a vehicle, data based on the tree structure of the drawing can be transmitted.

[0234] Figure 9b is a diagram illustrating a link between multiple domains.

[0235] Referring to the drawing, for in-vehicle signal transmission, a connection between two or more domain classifications can be performed.

[0236] Figure 9c is a drawing referenced in the description of the vehicle signal specification (VSS).

[0237] Referring to the drawing, route information (962), engine information (964), navigation information (966) or IVI display information (968) may be parsed by a parser (970) of a vehicle signal specification (VSS) and converted into a Markdown specification (992), a FrancalDL specification (994) or a JSON specification (996) through a Markdown generator (982), a FrancalDL generator (984) or a JSON generator (986).

[0238] Figure 10 is a flowchart explaining the conversion operation of the vehicle signal specification (VSS).

[0239] Referring to the drawing, a processor (175) within a central signal processing unit (170) or each processor (170Z1 to 170Z4) within a plurality of area signal processing units (170Z1 to 170Z4) receives a signal (S1010).

[0240] For example, a processor (175) within a central signal processing unit (170) or each processor (170Z1 to 170Z4) within a plurality of area signal processing units (170Z1 to 170Z4) may receive the arkdown specification (992), FrancalDL specification (994), or JSON specification (996) of FIG. 9c.

[0241] Next, the processor (175) within the central signal processing unit (170) or each processor (170Z1 to 170Z4) within the plurality of area signal processing units (170Z1 to 170Z4) determines whether a signal specification exists within the received signal (S1012), and if so, determines whether the signal specification is sensor data (S1014), and if so, generates a first variable corresponding to the sensor data (S1024).

[0242] Meanwhile, the processor (175) in the central signal processing unit (170) or each processor (170Z1 to 170Z4) in the plurality of area signal processing units (170Z1 to 170Z4) determines whether the data is actuator data (S1015) if it is not sensor data in step 1014 (S1014), and if so, can generate a second variable corresponding to the actuator data (S1025).

[0243] Meanwhile, the processor (175) within the central signal processing unit (170) or each processor (170Z1 to 170Z4) within the plurality of area signal processing units (170Z1 to 170Z4) determines whether the data is attribute data (S1017) if it is not actuator data in step 1015 (S1015), and if so, can generate a third variable corresponding to the attribute data (S1027).

[0244] Ultimately, the processor (175) within the central signal processing unit (170) or each processor (170Z1 to 170Z4) within the plurality of area signal processing units (170Z1 to 170Z4) can convert the received data into data based on the vehicle signal specification (VSS). Accordingly, high-speed and stable communication can be performed between the plurality of signal processing units.

[0245] Meanwhile, data conversion based on vehicle signal specifications (VSS) can be performed in middleware based on vehicle signal specifications (VSS).

[0246] For example, a vehicle signal specification (VSS)-based middleware (920) within a processor (175) within a central signal processing unit (170) may execute a code converter (not shown) to convert received data into vehicle signal specification (VSS)-based data.

[0247] As another example, the vehicle signal specification (VSS)-based middleware (920Z1 to 920Z4) within each processor (170Z1 to 170Z4) within the plurality of domain signal processing devices (170Z1 to 170Z4) can execute a code converter to convert received data into vehicle signal specification (VSS)-based data. Accordingly, high-speed and stable communication can be performed between the plurality of signal processing devices.

[0248] Figure 11 illustrates a case where a network error occurs between signal processing devices.

[0249] Referring to the drawing, among the multiple area signal processing devices (170Z1 to 170Z4) and the central signal processing device (170), a network error (ERa) may occur between the central signal processing device (170) and the first area signal processing device (170Z1).

[0250] Meanwhile, when a network error occurs between the central signal processing unit (170) and the first area signal processing unit (170Z1), the processor (175) in the central signal processing unit (170) can control to receive or transmit a message to the first area signal processing unit (170Z1) via the adjacent third area signal processing unit (170Z3).

[0251] In particular, when a network error occurs between the central signal processing unit (170) and the first area signal processing unit (170Z1), the processor (175) within the central signal processing unit (170) can control to receive or transmit a message to the second signal processing unit (170Z1) via the third signal processing unit (170Z3) using a message interface (920) based on the vehicle signal specification (VSS). Accordingly, stable communication can be performed even when a network error occurs.

[0252] Meanwhile, when a network error occurs between the central signal processing unit (170) and the first area signal processing unit (170Z1), the processor (175Z1) in the first area signal processing unit (170Z1) can control to receive or transmit a message to the central signal processing unit (170) via the adjacent third area signal processing unit (170Z3).

[0253] In particular, when a network error occurs between the central signal processing unit (170) and the first area signal processing unit (170Z1), the processor (175Z1) in the first area signal processing unit (170Z1) can control to receive or transmit a message to the central signal processing unit (170) via the adjacent third area signal processing unit (170Z3) using a message interface (920Z1) based on the vehicle signal specification (VSS). Accordingly, stable communication can be performed even when a network error occurs.

[0254] Meanwhile, among the multiple area signal processing devices (170Z1 to 170Z4) and the central signal processing device (170), a network error (ERb) may occur between the second area signal processing device (170Z2) and the fourth area signal processing device (170Z4).

[0255] Meanwhile, when a network error occurs between the second area signal processing device (170Z2) and the fourth area signal processing device (170Z4), the processor (175Z2) within the second area signal processing device (170Z2) can control the reception or transmission of a message to the fourth area signal processing device (170Z4) via the adjacent central signal processing device (170) using a message interface (920Z2) based on the vehicle signal specification (VSS). Accordingly, stable communication can be performed even when a network error occurs.

[0256] Meanwhile, when a network error occurs between the second area signal processing device (170Z2) and the fourth area signal processing device (170Z4), the processor (175Z4) within the fourth area signal processing device (170Z4) can control the reception or transmission of a message to the second area signal processing device (170Z2) via the adjacent central signal processing device (170) using a message interface (920Z4) based on the vehicle signal specification (VSS). Accordingly, stable communication can be performed even when a network error occurs.

[0257] Figure 12a is a diagram illustrating a data distribution service domain within a middleware based on a vehicle signal specification (VSS).

[0258] Referring to the drawing, a Data Distribution Service (DDS) domain can be executed within the middleware based on the Vehicle Signal Specification (VSS).

[0259] For example, as shown in FIG. 8A, a processor (175Z) within a domain signal processing device (170Z) can execute a data distribution service domain (921) together with a vehicle signal specification (VSS)-based middleware (920Z).

[0260] To this end, a processor (175Z) within a domain signal processing device (170Z) can execute a message interface (920) based on a vehicle signal specification (VSS).

[0261] As another example, as shown in FIG. 8b, a processor (175) within a central signal processing unit (170) may execute a data distribution service domain (924) together with a vehicle signal specification (VSS)-based middleware (920).

[0262] To this end, a processor (175) within a central signal processing unit (170) can execute a message interface (920Z) based on a vehicle signal specification (VSS).

[0263] Accordingly, input or output of various data is possible, and in particular, high-speed and stable communication can be performed between multiple signal processing devices with different operating systems.

[0264] Figure 12b is a drawing referenced in the description of Figure 12a.

[0265] Referring to the drawing, a processor (175) within a central signal processing unit (170) or a processor (175Z) within a domain signal processing unit (170Z) may execute an operating system (1120), execute a vehicle signal specification (VSS)-based middleware on the operating system (1120), and execute a data distribution service (DDS) domain (1110) on the operating system (1120) or the vehicle signal specification (VSS)-based middleware.

[0266] Meanwhile, a processor (175) in a central signal processing unit (170) or a processor (175Z) in a domain signal processing unit (170Z) can execute pre-installed applications (1131, 1132, 1133) or applications (1136, 1137, 1138) downloaded from an external server on a data distribution service (DDS) domain (1110).

[0267] Meanwhile, a processor (175) within a central signal processing unit (170) or a processor (175Z) within a domain signal processing unit (170Z) can control data to be received or transmitted through a data distribution service domain (1110) between a vehicle signal specification (VSS)-based middleware and an application (1131, 1132, 1133, 1136, 1137, 1138).

[0268] Meanwhile, the processor (175) in the central signal processing unit (170) or the processor (175Z) in the area signal processing unit (170Z) can control the data of the application (1136, 1137, 1138) downloaded from an external server to be converted into data based on a vehicle signal specification (VSS) and transmitted to a middleware based on a vehicle signal specification (VSS) or to another signal processing unit through the data distribution service domain (1110). Accordingly, high-speed and stable communication can be performed between a plurality of signal processing units.

[0269] Meanwhile, data conversion can be performed as described in Fig. 10.

[0270] Meanwhile, the processor (175) within the central signal processing unit (170) or the processor (175Z) within the area signal processing unit (170Z) can control data received from other signal processing units to be transmitted to the vehicle signal specification (VSS)-based middleware (920) through the data distribution service domain (1110), or to an external server (1400) or another signal processing unit. Accordingly, high-speed and stable communication can be performed between a plurality of signal processing units.

[0271] Figures 13a and 13b are drawings explaining the conversion and transmission of CAN messages.

[0272] First, referring to FIG. 13a, a processor (175Z) in a domain signal processing device (170Z) receives a CAN message including vehicle status information from a sensor device or the like (S1210).

[0273] For example, vehicle status information may include camera data, vehicle ABS abnormality information, vehicle tire pressure information, etc.

[0274] Next, the processor (175Z) within the area signal processing device (170Z) can output variable values ​​based on vehicle status information within the CAN message (S1220).

[0275] For example, a processor (175Z) within a domain signal processing device (170Z) may generate and output a first variable corresponding to the sensor data when the vehicle status information within the CAN message is sensor data.

[0276] As another example, a processor (175Z) within a domain signal processing device (170Z) may generate and output a second variable corresponding to actuator data when the vehicle status information within a CAN message is actuator data.

[0277] That is, the processor (175Z) within the area signal processing device (170Z) can convert a CAN message including vehicle status information into a message based on the vehicle signal specification (VSS) and output the converted message using the vehicle signal specification (VSS)-based middleware.

[0278] Next, a processor (175Z) within a domain signal processing unit (170Z) can transmit a message based on a vehicle signal specification (VSS) including vehicle status information to a central signal processing unit (170).

[0279] Next, the central signal processing unit (170) can transmit a message based on a vehicle signal specification (VSS) including vehicle status information to the display (180).

[0280] Accordingly, the display (180) can display vehicle status information based on a message based on the vehicle signal specification (VSS) (S1230).

[0281] Accordingly, high-speed and stable communication can be performed between multiple signal processing devices, and rapid display of vehicle status information becomes possible.

[0282] FIG. 13b illustrates that camera data received from the first area signal processing device (170Z1) is transmitted to the central signal processing device (170) through the signal path of PTHma, and transmitted to the second display (180b) through the signal path of PTHmb, so that the camera image is displayed on the second display (180b).

[0283] Referring to the drawing, the first area signal processing device (170Z1) can receive a CAN message including camera data from the front camera (195a) through CAN communication or the like.

[0284] Meanwhile, the processor (175Z1) in the first region signal processing device (170Z1) can generate and output a first variable corresponding to the camera data when the CAN message includes camera data.

[0285] That is, the processor (175Z1) within the first region signal processing device (170Z1) can convert a CAN message including camera data into a message based on the vehicle signal specification (VSS) and output the converted message using the vehicle signal specification (VSS)-based middleware.

[0286] In addition, the central signal processing unit (170) can receive a message based on a vehicle signal specification (VSS) including camera data from the first area signal processing unit (170Z1).

[0287] At this time, the processor (175) within the central signal processing unit (170) can quickly receive a message based on the vehicle signal specification (VSS) including camera data by using the message interface (920) based on the vehicle signal specification (VSS).

[0288] Meanwhile, the processor (175) within the central signal processing unit (170) can transmit a message based on the vehicle signal specification (VSS) including camera data to the second display (180b) using a message interface (920) based on the vehicle signal specification (VSS).

[0289] At this time, the second display (180b) can receive a vehicle signal specification (VSS)-based message containing camera data using a vehicle signal specification (VSS)-based message interface (1215) and display a camera image corresponding to the camera data. Accordingly, rapid transmission of camera data and display of camera images based thereon are enabled.

[0290] Meanwhile, the processor (175) within the central signal processing unit (170) may also receive a CAN message containing camera data.

[0291] In this case, the processor (175) within the central signal processing unit (170) can control to convert a CAN message including camera data into a vehicle signal specification (VSS)-based message and transmit the converted vehicle signal specification (VSS)-based message to the display (180). Accordingly, high-speed and stable communication can be performed between a plurality of signal processing units.

[0292] Figures 14a and 14b are drawings explaining the generation and transmission of CAN messages according to changes in sensor settings.

[0293] First, referring to FIG. 14a, the processor (175) within the central signal processing unit (170) can receive sensor setting change data through the second display (180b) when a sensor setting change is performed (S1310).

[0294] For example, sensor setting change data may include camera setting change data, vehicle ABS setting change data, vehicle tire pressure setting change data, etc.

[0295] Next, the processor (175) within the central signal processing unit (170) can output variable values ​​based on sensor setting change data (S1320).

[0296] For example, a processor (175Z) within a domain signal processing device (170Z) may generate and output a first variable corresponding to the sensor data when the vehicle status sensor setting change data within a CAN message is sensor data.

[0297] As another example, a processor (175Z) within a domain signal processing device (170Z) may generate and output a second variable corresponding to the actuator data when the sensor setting change data is actuator data.

[0298] That is, the processor (175) within the central signal processing unit (170) can output a message based on the vehicle signal specification (VSS) including sensor setting change data by using middleware based on the vehicle signal specification (VSS).

[0299] Next, the processor (175) within the central signal processing unit (170) can transmit a message based on the vehicle signal specification (VSS) including sensor setting change data to the area signal processing unit (170Z).

[0300] Next, a processor (175Z) within a domain signal processing device (170Z) can convert a message based on a vehicle signal specification (VSS) including sensor setting change data into a CAN message (S1330).

[0301] Next, the processor (175Z) within the area signal processing device (170Z) can transmit a CAN message including sensor setting change data to a sensor device, etc.

[0302] Accordingly, high-speed and stable communication can be performed between multiple signal processing devices, and rapid transmission of sensor setting change data becomes possible.

[0303] FIG. 14b illustrates that when sensor setting change data is input through the second display (180b), it is transmitted to the central signal processing device (170) through the signal path of PTHna, and to the first area signal processing device (170Z1) and the first camera (195a) through the signal path of PTHnb.

[0304] Referring to the drawing, the second display (180b) can transmit a vehicle signal specification (VSS)-based message including sensor setting change data to the central signal processing unit (170) using a vehicle signal specification (VSS)-based message interface (1215).

[0305] Meanwhile, the central signal processing unit (170) can receive a message based on a vehicle signal specification (VSS) including sensor setting change data and transmit it to the first area signal processing unit (170Z1) via Ethernet communication.

[0306] Next, the first area signal processing device (170Z1) can convert a vehicle signal specification (VSS)-based message including sensor setting change data into a CAN message including sensor setting change data, and transmit the CAN message including sensor setting change data to the first camera (195a).

[0307] Accordingly, changes to the camera settings of the first camera (195a) can be performed quickly.

[0308] Meanwhile, the processor (175) of the central signal processing unit (170) can also convert sensor setting change data into a CAN message and transmit it.

[0309] That is, when a sensor setting change is performed through the display (180), the processor (175) of the central signal processing unit (170) can control to convert the received sensor setting change data into a vehicle signal specification (VSS)-based message, convert the converted vehicle signal specification (VSS)-based message into a CAN message, and transmit the converted CAN message to the first region signal processing unit (170Z1) via CAN communication. Accordingly, high-speed and stable communication can be performed between a plurality of signal processing units.

[0310] FIGS. 15a and 15b are drawings explaining the operation of searching for and mapping the vehicle signal meaning of the received data when the data received from an external server (1400) is not mapped to a data distribution service domain.

[0311] First, referring to FIG. 15a, the central signal processing unit (170) can be turned on (S1410).

[0312] Next, the processor (175) within the central signal processing unit (170) can receive data from an external server (1400).

[0313] For example, a processor (175) within a central signal processing unit (170) may receive data related to media volume settings from an external server (1400).

[0314] Meanwhile, the processor (175) within the central signal processing unit (170) searches for the vehicle signal meaning of the received data (S1415) if the data received from the external server (1400) is not mapped to a vehicle signal specification (VSS)-based message within the distributed service domain (1410).

[0315] Next, the processor (175) within the central signal processing unit (170) determines whether the vehicle signal meaning of the data received as a result of a search through an external server (1400) or the like corresponds to a media volume setting (S1420), and if so, can map it to a vehicle signal specification (VSS)-based message including the media volume setting within the distributed service domain (1410) (S1425).

[0316] Next, the processor (175) within the central signal processing unit (170) can control the media volume settings of the audio output unit (185) and the like based on a vehicle signal specification (VSS)-based message including the media volume settings (S1430). Accordingly, the media volume settings can be stably performed.

[0317] Figure 15b illustrates a system including a central signal processing unit (170) and an external server (1400).

[0318] Referring to the drawing, the central signal processing unit (170) can execute a hardware driver (1405), an operating system, a vehicle signal specification (VSS)-based middleware (1420), and a data distribution service domain (1410).

[0319] Meanwhile, the data distribution service domain (1410) can exchange data with the basic software (1428) or exchange data with downloaded software.

[0320] Meanwhile, the processor (175) within the central signal processing unit (170) can receive data from an external server (1400).

[0321] For example, a processor (175) within a central signal processing unit (170) may receive data (1410) related to media volume settings from among cruise control data (1401), software data (1403), and data (1410) related to media volume settings from an external server (1400).

[0322] Meanwhile, the processor (175) within the central signal processing unit (170) can search for the vehicle signal meaning of the received data if the data (1410) related to media volume settings received from the external server (1400) is not mapped to a vehicle signal specification (VSS)-based message within the distributed service domain (1410).

[0323] Meanwhile, the processor (175) within the central signal processing unit (170) can map, if the vehicle signal meaning of the data received as a result of a search through an external server (1400) or the like corresponds to a media volume setting, a vehicle signal specification (VSS)-based message including the media volume setting within the distributed service domain (1410).

[0324] Next, the processor (175) within the central signal processing unit (170) can control the media volume settings of the audio output unit (185), etc., based on a vehicle signal specification (VSS)-based message including the media volume settings. Accordingly, the media volume settings can be stably performed.

[0325] According to FIGS. 15A and 15B, the central signal processing unit (170) processor (175) can control the operation of the received data by searching for and mapping the vehicle signal meaning of the received data when the data received from the external server (1400) is not mapped to the data distribution service domain (1410). Accordingly, stable communication can be performed.

[0333] Accordingly, during the operation of the new device (1510), a recommendation function related to the new device (1510) can be executed.

[0334] In particular, if the new device (1510) is an ice warning sensor, road ice notification and recommendation functions can be executed.
