[0142] And, the first virtualization machine (not shown) can transmit the processed data to the second virtualization machine to the third virtualization machine (not shown).

[0143] Accordingly, among the first to third virtualization machines (not shown), only the first virtualization machine (not shown) receives sensor data, communication data, or external input data from a plurality of sensor devices and performs signal processing, thereby reducing the signal processing burden on other virtualization machines and enabling 1:N data communication, which enables synchronization when sharing data.

[0144] Meanwhile, the first virtualization machine (not shown) can control the sharing of the same data with the second virtualization machine (not shown) and the third virtualization machine (not shown) by writing data to the shared memory (508).

[0145] For example, the first virtualization machine (not shown) can record vehicle sensor data, the location information data, the camera image data, or the touch input data in a shared memory (508) and control the sharing of the same data with the second virtualization machine (not shown) and the third virtualization machine (not shown). Accordingly, data sharing in a 1:N manner becomes possible.

[0146] Ultimately, by performing most of the data processing on the first virtualization machine (not shown), 1:N data sharing becomes possible.

[0147] Meanwhile, the first virtualization machine (not shown) within the processor (175) can control the second virtualization machine (not shown) and the third virtualization machine (not shown) to set up a shared memory (508) based on the hypervisor (505) for the same data transmission.

[0148] Meanwhile, the signal processing device (170a, 170b) can process various signals such as audio signals, video signals, and data signals. To this end, the signal processing device (170a, 170b) can be implemented in the form of a System On Chip (SOC).

[0149] Meanwhile, the signal processing device (170a, 170b) of FIG. 4 can correspond to the signal processing device (170a1, 170a2) of FIG. 5a and below.

[0150] FIGS. 5a to 5d are drawings illustrating various examples of vehicle control devices.

[0151] FIG. 5a illustrates an example of a vehicle control device according to an embodiment of the present disclosure.

[0152] Referring to the drawings, a vehicle control device (800a) 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).

[0158] Meanwhile, the data received by the signal processing device (170a1, 170a2) may include camera data or sensor data.

[0159] For example, sensor data within the vehicle may include at least one of vehicle wheel speed data, vehicle direction data, vehicle location data (GPS data), vehicle angle data, vehicle speed data, vehicle acceleration data, vehicle tilt data, vehicle forward / reverse data, battery data, fuel data, tire data, vehicle lamp data, vehicle interior temperature data, vehicle interior humidity data, vehicle external radar data, and vehicle external lidar data.

[0160] Meanwhile, camera data may include external vehicle camera data and internal vehicle camera data.

[0161] Meanwhile, the signal processing device (170a1, 170a2) can execute multiple virtualization machines (820, 830, 840) based on safety standards.

[0162] In the drawing, a processor (175) within a signal processing unit (170a) executes a hypervisor (505) and, on the hypervisor (505), executes first to third virtualization machines (820 to 840) according to the Automotive Safety Integrity Level (Automotive SIL; ASIL).

[0163] The first virtualization machine (820) may be a virtualization machine corresponding to Quality Management (QM), which is the lowest safety level and non-mandatory grade in the Automotive Safety Integrity Level (ASIL).

[0164] The first virtualization machine (820) can run an operating system (822), a container runtime (824) on the operating system (822), and containers (827, 829) on the container runtime (824).

[0165] The second virtualization machine (830) may be a virtualization machine corresponding to ASIL A or ASIL B, where the sum of Severity, Exposure, and Controllability in the Automotive Safety Integrity Level (ASIL) is 7 or 8.

[0166] The second virtualization machine (830) can run an operating system (832), a container runtime (834) on the operating system (832), and containers (837, 839) on the container runtime (834).

[0167] The third virtualization machine (840) may be a virtualization machine corresponding to ASIL C or ASIL D, in which the sum of Severity, Exposure, and Controllability in the Automotive Safety Integrity Level (ASIL) is 9 or 10.

[0168] Meanwhile, ASIL D can correspond to the grade requiring the highest level of safety.

[0169] The third virtualization machine (840) can run a safety operating system (842) and an application (845) on the operating system (842).

[0170] Meanwhile, the third virtualization machine (840) may also run a safety operating system (842), a container runtime (844) on the safety operating system (842), and a container (847) on the container runtime (844).

[0171] Meanwhile, unlike the drawing, the third virtualization machine (840) may also be executed through a separate core rather than the processor (175). This will be described later with reference to FIG. 5b.

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

[0173] Referring to the drawings, a vehicle control 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).

[0174] The vehicle control device (800b) of Fig. 5b is similar to the vehicle control device (800a) of Fig. 5a, but the signal processing device (170a1) differs in some ways from the signal processing device (170a1) of Fig. 5a.

[0175] To describe the difference, the signal processing device (170a1) may be equipped with a processor (175) and a second processor (177).

[0176] A processor (175) within a signal processing unit (170a1) executes a hypervisor (505) and, on the hypervisor (505), executes first and second virtualization machines (820 to 830) according to the Automotive Safety Integrity Level (Automotive SIL; ASIL).

[0177] The first virtualization machine (820) can run an operating system (822), a container runtime (824) on the operating system (822), and containers (827, 829) on the container runtime (824).

[0178] The second virtualization machine (830) can run an operating system (832), a container runtime (834) on the operating system (832), and containers (837, 839) on the container runtime (834).

[0179] Meanwhile, the second processor (177) in the signal processing device (170a1) can execute the third virtualization machine (840).

[0180] The third virtualization machine (840) can run a safety operating system (842), an AUTOSAR (845) on the operating system (842), and an application (845) on the AUTOSAR (845). That is, unlike FIG. 5a, it can further run an AUTOSAR (846) on the operating system (842).

[0181] Meanwhile, the third virtualization machine (840) may run a safety operating system (842), a container runtime (844) on the safety operating system (842), and a container (847) on the container runtime (844), similar to FIG. 5a.

[0182] Meanwhile, the third virtualization machine (840), which requires a high level of safety, is preferably executed on a second processor (177), which is a different core or a different processor, unlike the first and second virtualization machines (820 to 830).

[0183] Meanwhile, in the signal processing devices (170a1, 170a2) of FIG. 5a and 5b, the second signal processing device (170a2) can operate as a backup when the first signal processing device (170a) malfunctions.

[0184] Alternatively, signal processing devices (170a1, 170a2) may operate simultaneously, with the first signal processing device (170a) operating as the main and the second signal processing device (170a2) operating as the sub. This is described with reference to FIG. 5c and FIG. 5d.

[0185] FIG. 5c illustrates another example of a vehicle control device according to an embodiment of the present disclosure.

[0186] Referring to the drawings, a vehicle control 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).

[0187] Meanwhile, in the drawing, two signal processing devices (170a1, 170a2) are exemplified, but this is exemplified for backup purposes, and one is also possible.

[0188] Meanwhile, the signal processing device (170a1, 170a2) may be named as an HPC (High Performance Computing) signal processing device.

[0189] A plurality of area signal processing devices (170Z1~170Z4) are positioned in each area (Z1~Z4) and can transmit sensor data to signal processing devices (170a1, 170a2).

[0190] The signal processing device (170a1, 170a2) receives data via wire from a plurality of area signal processing devices (170Z1~170Z4) or a communication device (120).

[0191] In the drawing, data is exchanged based on wired communication between the signal processing device (170a1, 170a2) and the plurality of area signal processing devices (170Z1~170Z4), and data is exchanged based on wireless communication between the signal processing device (170a1, 170a2) and the server (400), but data can be exchanged based on wireless communication between the communication device (120) and the server (400), and data can be exchanged based on wired communication between the signal processing device (170a1, 170a2) and the communication device (120).

[0192] Meanwhile, the data received by the signal processing device (170a1, 170a2) may include camera data or sensor data.

[0193] Meanwhile, the processor (175) in the first signal processing device (170a1) among the signal processing devices (170a1, 170a2) can execute a hypervisor (505) and, on the hypervisor (505), execute a safety virtualization machine (860) and a non-safety virtualization machine (870), respectively.

[0194] Meanwhile, the processor (17b5) in the second signal processing unit (170a2) among the signal processing units (170a1, 170a2) can execute the hypervisor (505b) and, on the hypervisor (505), execute only the safety virtualization machine (880).

[0195] According to this method, 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.

[0196] Meanwhile, high-speed network communication can be performed between the first signal processing device (170a1) and the second signal processing device (170a2).

[0197] FIG. 5d illustrates another example of a vehicle control device according to an embodiment of the present disclosure.

[0198] Referring to the drawings, a vehicle control 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).

[0199] The vehicle control device (800d) of FIG. 5d is similar to the vehicle control device (800c) of FIG. 5c, but the second signal processing device (170a2) differs in some ways from the second signal processing device (170a2) of FIG. 5c.

[0200] The processor (17b5) in the second signal processing unit (170a2) of FIG. 5d can execute a hypervisor (505b) and, on the hypervisor (505), execute a safety virtualization machine (880) and a non-safety virtualization machine (890), respectively.

[0201] That is, unlike Fig. 5c, the difference is that the processor (17b5) in the second signal processing unit (170a2) further executes the non-safety virtualization machine (890).

[0202] According to this method, since the processing of safety and non-safety is separated by the first signal processing device (170a1) and the second signal processing device (170a2), it is possible to improve stability and processing speed.

[0203] FIG. 6 is an example of a vehicle control device according to an embodiment of the present disclosure.

[0204] Referring to the drawings, a vehicle control device (800) according to an embodiment of the present disclosure comprises a plurality of area signal processing devices (170Z1 to 170Z4) and a plurality of signal processing devices (170a, 170b).

[0205] The signal processing device (170a, 170b) at this time is a high-performance centralized signal processing and control device having multiple CPUs and GPUs, etc., and can be named as an HPC (High Performance Computing) signal processing device or a central signal processing device.

[0206] Multiple area signal processing devices (170Z1~170Z4) and signal processing devices (170a, 170b) are connected by wired cables (CB1~CB4).

[0207] Meanwhile, multiple area signal processing devices (170Z1~170Z4) can be connected to each other by wired cables (CBa~CBd).

[0208] The wired cable (CBa~CBd) at this time may include a CAN communication cable, an Ethernet communication cable, or a PCI Express cable.

[0209] Meanwhile, the signal processing device (170a, 170b) according to the embodiment of the present disclosure comprises at least one processor (175, 178, 177) and a large-capacity storage device (925).

[0210] For example, at least one processor may be a central processor.

[0211] Meanwhile, the signal processing device (170a, 170b) according to the embodiment of the present disclosure may further include a graphics processor or a neural processor.

[0212] Meanwhile, sensor data can be transmitted from at least one of the multiple area signal processing devices (170Z1 to 170Z4) to the signal processing devices (170a, 170b). In particular, the sensor data can be stored in a storage device (925) within the signal processing devices (170a, 170b).

[0213] The sensor data at this time may include at least one of camera data, lidar data, radar data, vehicle direction data, vehicle position data (GPS data), vehicle angle data, vehicle speed data, vehicle acceleration data, vehicle tilt data, vehicle forward / reverse data, battery data, fuel data, tire data, vehicle lamp data, vehicle interior temperature data, and vehicle interior humidity data.

[0214] In the drawing, 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 signal processing devices (170a, 170b) via a second area signal processing device (170Z2) and a third area signal processing device (170Z3), etc.

[0215] Meanwhile, since the data reading or writing speed to the storage device (925) is faster than the network speed when sensor data is transmitted from at least one of the multiple area signal processing devices (170Z1~170Z4) to the signal processing device (170a, 170b), it is desirable to perform multipath routing so that network bottlenecks do not occur.

[0216] To this end, the signal processing device (170a, 170b) according to the embodiment of the present disclosure can perform multipath routing based on a Software Defined Network (SDN). Accordingly, a stable network environment can be secured when reading or writing data to the storage device (925). Furthermore, since data can be transmitted to the storage device (925) using multiple paths, data can be transmitted by dynamically changing the network configuration.

[0217] Data communication between a plurality of area signal processing devices (170Z1~170Z4) and signal processing devices (170a, 170b) within a vehicle control device (800) according to an embodiment of the present disclosure is preferably Peripheral Component Interconnect Express communication for high-bandwidth, low-latency communication.

[0218] FIG. 7 is an example of an internal block diagram of a vehicle control device according to an embodiment of the present disclosure.

[0219] Referring to the drawings, a vehicle control device (700) according to one embodiment of the present disclosure includes a first Ethernet switch (722), a second Ethernet switch (724), a first signal processing device (170a) that receives data from the first Ethernet switch (722) or the second Ethernet switch (724), and a second signal processing device (170b) that receives data from the first Ethernet switch (722) or the second Ethernet switch (724).

[0220] Accordingly, the signal processing device (170a, 170b) can be operated stably. In particular, by using multiple Ethernet switches (722, 724), the signal processing device (170a, 170b) can be operated stably even when the operation of any one of the Ethernet switches is interrupted.

[0221] A vehicle control device (700) according to one embodiment of the present disclosure includes a first DC / DC converter (715) that performs level conversion based on a first input voltage (VD1) and a second DC / DC converter (717) that performs level conversion based on a second input voltage (VD2).

[0222] Meanwhile, the first Ethernet switch (722) operates based on the DC voltage (VDa) from the first DC / DC converter (715).

[0223] Meanwhile, the second Ethernet switch (724) operates based on the DC voltage (VDb) from the second DC / DC converter (717).

[0224] In this way, by providing multiple DC / DC converters, multiple Ethernet switches (722, 724) can be operated stably, and consequently, signal processing devices (170a, 170b) can be operated stably.

[0225] Meanwhile, the first signal processing device (170a) or the second signal processing device (170b) can receive data from the second Ethernet switch (724) when the operation of the first Ethernet switch (722) is interrupted. Accordingly, the signal processing devices (170a, 170b) can be operated stably.

[0226] Meanwhile, the first signal processing device (170a) or the second signal processing device (170b) can receive data from the first Ethernet switch (722) when the operation of the second Ethernet switch (724) is interrupted. Accordingly, the signal processing devices (170a, 170b) can be operated stably.

[0227] Meanwhile, a vehicle control device (700) according to one embodiment of the present disclosure may further include an external component high-speed connection (PCI Express) switch (725).

[0228] Meanwhile, the external component high-speed connection switch (725) can transmit or receive signals based on external component high-speed connection (PCI Express) communication between the first Ethernet switch (722), the second Ethernet switch (724), the first signal processing device (170a), the second signal processing device (170b), or memory (140) such as NVMe or SSD.

[0229] For example, the first signal processing device (170a) or the second signal processing device (170b) can receive data from the external component high-speed connection switch (725) when the operation of the first Ethernet switch (722) and the second Ethernet switch (724) is interrupted. Accordingly, the signal processing devices (170a, 170b) can be operated reliably.

[0230] Meanwhile, it is preferable that the data transmission rate of the external component high-speed connection switch (725) is greater than the data transmission rate of the first Ethernet switch (722) or the second Ethernet switch (724).

[0231] For example, if the transmission rate or transmission speed of the first data input from the outside is less than or equal to the first reference value, the first Ethernet switch (722) or the second Ethernet switch (724) is operated so that the first data can be input to the first signal processing device (170a) or the second signal processing device (170b).

[0232] As another example, if the transmission rate or transmission speed of the second data input from the outside exceeds the first reference value, the first Ethernet switch (722) or the second Ethernet switch (724) does not operate and the external component high-speed connection switch (725) operates so that the second data can be input to the first signal processing device (170a) or the second signal processing device (170b).

[0233] Accordingly, the signal processing device (170a, 170b) can be operated efficiently. In addition, high-speed data transmission is possible based on the external component high-speed connection switch (725).

[0234] Meanwhile, the first Ethernet switch (722) and the second Ethernet switch (724) can transmit or receive Ethernet communication-based signals to or from external area signal processing devices (170Z1~170Z4) as interface devices (720).

[0235] To this end, the interface device (720) can be electrically connected to wired cables (CB1 to CB4).

[0236] Meanwhile, the first Ethernet switch (722) and the second Ethernet switch (724) may be equipped with a multi port for communication with external area signal processing devices (170Z1~170Z4).

[0237] Meanwhile, the first Ethernet switch (722) can receive sensor data from the radar sensor or lidar sensor and transmit it to the first signal processing device (170a). Accordingly, the sensor data from the radar sensor or lidar sensor can be transmitted reliably.

[0238] Meanwhile, the second Ethernet switch (724) can receive camera data and transmit it to the second signal processing device (170b). Accordingly, camera data can be transmitted reliably.

[0239] Meanwhile, the interface device (720) may further be equipped with an external component high-speed connection switch (725).

[0240] For example, the first Ethernet switch (722) or the second Ethernet switch (724) may receive sensor data from a radar sensor or a lidar sensor and transmit it to the first signal processing device (170a) or the second signal processing device (170b), and the external component high-speed connection switch (725) may receive camera data and transmit it to the first signal processing device (170a) or the second signal processing device (170b). Accordingly, efficient transmission according to the type of data becomes possible.

[0241] Meanwhile, the first Ethernet switch (722) can operate based on the DC voltage (VDb) of the second DC / DC converter (717) when the operation of the first DC / DC converter (715) is interrupted. Accordingly, the signal processing device (170a, 170b) can be operated stably.

[0242] Meanwhile, the second Ethernet switch (724) can operate based on the DC voltage (VDa) of the first DC / DC converter (715) when the second DC / DC converter (717) stops operating. Accordingly, the signal processing device (170a, 170b) can be operated stably.

[0243] Meanwhile, the first DC / DC converter (715) can output multiple DC voltages. For example, the first DC / DC converter (715) can output a DC voltage of approximately 5V and a DC voltage of approximately 3.3V. Accordingly, the signal processing device (170a, 170b) can be operated stably.

[0244] Meanwhile, the second DC / DC converter (717) can output multiple DC voltages. For example, the second DC / DC converter (717) can output a DC voltage of approximately 5V and a DC voltage of approximately 3.3V. Accordingly, the signal processing device (170a, 170b) can be operated stably.

[0245] Meanwhile, a DC voltage of approximately 5V output from the first DC / DC converter (715) or the second DC / DC converter (717) can be input to the first Ethernet switch (722), camera (195), audio output unit (185), etc.

[0246] Meanwhile, a DC voltage of approximately 3.3V output from the first DC / DC converter (715) or the second DC / DC converter (717) can be input to a plurality of displays (180a to 180c), memory (140), etc.

[0247] Meanwhile, a vehicle control device (700) according to one embodiment of the present disclosure may further include a first voltage interface (711) that receives each voltage through a plurality of ports, selects one of them, and outputs a first input voltage (VD1), and a second voltage interface (712) that receives each voltage through a plurality of ports, selects one of them, and outputs a second input voltage (VD2). Accordingly, the signal processing device (170a, 170b) can be operated stably using the plurality of voltage interfaces (711, 712).

[0248] For example, the first voltage interface (711) can output a first input voltage (VD1) by selecting either a first battery voltage or a second battery voltage. At this time, the first input voltage (VD1) may be approximately 12V.

[0249] Meanwhile, the first input voltage (VD1) output from the first voltage interface (711) can be input to the first Ethernet switch (722), the external component high-speed connection switch (725), and the first DC / DC converter (715).

[0250] Meanwhile, the first DC / DC converter (715) can output multiple DC voltages by lowering the level of the first input voltage (VD1).

[0251] For example, the second voltage interface (712) can output a second input voltage (VD2) by selecting either the first battery voltage or the second battery voltage. At this time, the second input voltage (VD2) may be approximately 12V.

[0252] Meanwhile, the second input voltage (VD2) output from the second voltage interface (712) can be input to the second Ethernet switch (724) and the second DC / DC converter (717).

[0253] Meanwhile, the second DC / DC converter (717) can output multiple DC voltages by lowering the level of the second input voltage (VD2).

[0254] Meanwhile, a vehicle control device (700) according to one embodiment of the present disclosure may further include a first microcomputer (730) that exchanges data with a first signal processing device (170a) and a second microcomputer (732) that exchanges data with a second signal processing device (170b).

[0255] For example, the first microcomputer (730) or the second microcomputer (732) is equipped with an M core and can execute a safety operating system (OS) and applications on the safety operating system (OS).

[0256] Meanwhile, the first microcomputer (730) or the second microcomputer (732) can operate as an auxiliary unit in the event of a failure of the first signal processing unit (170a) or the second signal processing unit (170b). Accordingly, the signal processing units (170a, 170b) can be operated stably.

[0257] Meanwhile, it is preferable that the safety level of the first microcomputer (730) or the second microcomputer (732) is higher than the safety level of the first signal processing device (170a) or the second signal processing device (170b).

[0258] For example, the safety level of the first microcomputer (730) or the second microcomputer (732) corresponds to ASIL D, and the safety level of the first signal processing unit (170a) or the second signal processing unit (170b) may correspond to ASIL A, B, or C. Accordingly, the first microcomputer (730) or the second microcomputer (732) can be operated stably.

[0259] Meanwhile, a vehicle control device (700) according to one embodiment of the present disclosure may further include a power control unit (719) that transmits a boot signal to a first signal processing device (170a) or a second signal processing device (170b).

[0260] For example, when the vehicle control unit (700) is powered on, the power control unit (719) can transmit a boot signal to the first signal processing unit (170a) or the second signal processing unit (170b).
