[0054] Hereinafter, the operating principle and embodiments of the present disclosure will be described with reference to the drawings.

[0055] Figure 1 Shows a braking device including an electronic control device according to an embodiment, and Figure 2 Shows an example of an output signal from an ultraviolet sensor included in an electronic control device according to an embodiment.

[0056] Mounted onFigure 1 The electronic control device 10 in the braking device 1 shown in Figure 1 may be an example of the electronic control device according to the present disclosure. The electronic control device according to the present disclosure may correspond to any one of the electrical / electronic devices installed in a vehicle. For example, the electronic control device 10 according to the present disclosure may be an engine control unit (ECU), a transmission control unit (TCU), an electronic control unit (ECU) of an electric power steering device (EPS), a body control unit (BCU), or a vehicle control unit (VCU).

[0057] As Figure 1 shown in Figure 1 , the braking device 1 may include an electronic control device 10, a valve 20, and / or a motor 30. Figure 1 The valve 20 and the motor 30 shown in Figure 1 may not be essential components of the present disclosure, and the valve 20 and the motor 30 may be omitted.

[0058] The braking device 1 may supply pressure (hereinafter referred to as "hydraulic pressure") of a pressurized medium (e.g., brake oil, etc.) for braking the vehicle to a plurality of wheels installed in the vehicle.

[0059] For example, the braking device 1 may include a hydraulic supplier for generating hydraulic pressure and a hydraulic controller for controlling the generated hydraulic pressure. For example, the hydraulic supplier may include a piston-cylinder pump or a rotary pump driven by the motor 30. For example, the hydraulic controller may include a flow path extending from the hydraulic supplier to a wheel cylinder installed in a wheel of the vehicle and a plurality of valves for opening or closing the flow path.

[0060] The motor 30 may supply power (torque) for generating hydraulic pressure to the piston-cylinder pump or the rotary pump. For example, the torque of the motor 30 may be converted into a translational force by a power conversion device (e.g., a spindle nut, a pinon-rack, etc.), and the piston of the piston-cylinder pump may perform a translational motion by the translational force. In addition, the rotor of the rotary pump may rotate by the torque of the motor 30.

[0061] For example, the motor 30 may include a rotor and a stator, and the rotor or the stator may include a plurality of coils for generating a rotating magnetic field. The motor 30 may be driven by a motor drive current supplied to the plurality of coils.

[0062] The valve 20 may allow or block the hydraulic pressure generated by the hydraulic supplier and supplied to the wheel cylinder. In addition, the valve 20 may modulate or regulate the hydraulic pressure generated by the hydraulic supplier and supplied to the wheel cylinder.

[0063] For example, the valve 20 may include an electronically controllable solenoid valve. The solenoid valve may include a coil for generating a magnetic field. The valve 20 may be opened (normally closed valve) or closed (normally open valve) by a valve drive current supplied to the coil.

[0064] The electronic control device 10 can control the motor 30 and / or the valve 20 in response to the driver's control or the control by the upper control device.

[0065] For example, as Figure 1 shown, the electronic control device 10 can include a pedal sensor 11, an ultraviolet sensor 12, a valve drive circuit 13, a motor drive circuit 14, a power circuit 15, and / or a processor 16. Figure 1 The pedal sensor 11, the valve drive circuit 13, and the motor drive circuit 14 shown may not be essential components of the electronic control device 10 according to the embodiment, and the pedal sensor 11, the valve drive circuit 13, and the motor drive circuit 14 may be omitted.

[0066] The pedal sensor 11 can detect the movement of the brake pedal as the driver's braking intention and output an electrical signal (hereinafter referred to as "pedal signal") corresponding to the movement of the brake pedal. The brake pedal can be moved by the driver, and the pedal sensor 11 can detect the movement of the brake pedal by the driver. The pedal sensor 11 can output a pedal signal corresponding to the displacement or the movement speed of the brake pedal to the processor 16.

[0067] The ultraviolet sensor 12 can be disposed inside the electronic control device 10 that blocks external light and detect the ultraviolet light generated in the electronic control device 10. For example, the ultraviolet sensor 12 can detect ultraviolet-C (UV-C) generated in the electronic control device 10.

[0068] Due to a failure of an electronic circuit, a failure of a power supply, etc., a spark or an arc may occur inside the electronic control device 10. For example, when a sudden current flows into the power circuit 15 or a sudden voltage is applied to the power circuit 15, the insulation between the power terminals (or power lines) and the ground terminals (or ground wires) of the power circuit 15 may break down, which may cause a spark between the power terminals and the ground terminals. In addition, when the current supplied to the motor 30 or the valve 20 is suddenly cut off, due to the induced electromotive force of the coil included in the motor 30 or the valve 20, the insulation between the terminals of the motor 30 or the valve 20 may break down, which may cause repeated arcs between the terminals of the motor 30 or the valve 20.

[0069] The spark or arc occurring inside the electronic control device 10 may cause a fire in the electronic control device 10. For example, there are many flammable components inside the electronic control device 10, and the spark or arc may cause a fire in the flammable components.

[0070] A fire occurring in the electronic control device 10 may spread throughout the vehicle. For example, when power is continuously supplied to the electronic control device 10 ignited by a spark or an arc, the spark or the arc may recur, and thus, the fire in the electronic control device 10 may spread. In addition, the fire in the electronic control device 10 may spread throughout the vehicle along the power lines or communication lines inside the vehicle.

[0071] Therefore, a spark or an arc occurring within the electronic control device 10 may cause a fire in the electronic control device 10 and even a fire in the vehicle.

[0072] A spark or an arc may include the emission of ultraviolet light, particularly UV-C. UV-C may be light having a wavelength range of approximately 100 nm to approximately 280 nm. Since UV-C is absorbed by the ozone layer, UV-C is generally undetectable. Therefore, detecting UV-C reduces the possibility of false detection of a spark or an arc.

[0073] The ultraviolet sensor 12 may include a photodiode for detecting ultraviolet light, particularly UV-C. For example, the photodiode may be made of a semiconductor material capable of absorbing UV-C. For example, the photodiode may include a PN junction diode made of gallium oxide (Ga2O3), gallium nitride (GaN), silicon carbide (SiC), or diamond (C). The bandgap of gallium oxide may be in the range of approximately 4.4 eV to 4.9 eV, and the photodiode made of gallium oxide may absorb UV-C having a wavelength range of approximately 100 nm to approximately 280 nm.

[0074] Therefore, when UV-C is detected by the ultraviolet sensor 12 within the electronic control device 10, the occurrence of a spark or an arc can be determined.

[0075] The ultraviolet sensor 12 may output an electrical signal corresponding to the detection of ultraviolet light (hereinafter referred to as "ultraviolet detection signal") to the processor 16. As Figure 2 shown, when no UV-C is incident on the photodiode, the ultraviolet sensor 12 may output a "low" signal close to "0" V. In contrast, when UV-C is incident on the photodiode at time "0", the ultraviolet sensor 12 may output a "high" signal, i.e., the ultraviolet detection signal.

[0076] The ultraviolet sensor 12 may include a plurality of ultraviolet sensors positioned at different locations. For example, the ultraviolet sensor 12 may include a first ultraviolet sensor 610 and a second ultraviolet sensor 620. The first ultraviolet sensor is mounted around the power receiving terminal of the power circuit 15 for receiving power from an external power source, and the second ultraviolet sensor is mounted around the power supply terminal for supplying motor drive current to the motor 30. Although the first ultraviolet sensor 610 and the second ultraviolet sensor 620 are mounted at different locations, they may have substantially the same structure and function.

[0077] The valve drive circuit 13 may receive a control signal from the processor 16 and control the valve drive current for driving the valve 20 in response to the control signal from the processor 16. For example, the valve drive circuit 13 may control the valve drive current to open the valve 20 in response to an open signal from the processor 16. In addition, the valve drive circuit 13 may control the valve drive current to close the valve 20 in response to a close signal from the processor 16.

[0078] The valve drive circuit 13 may include a switching circuit for controlling the valve drive current to be supplied to the valve 20. The switching circuit may include a transistor that is turned on / off in response to a control signal from the processor 16.

[0079] The motor drive circuit 14 may receive a control signal from the processor 16 and control the motor drive current for driving the motor 30 in response to the control signal from the processor 16. The motor drive circuit 14 may control the motor drive current in response to a compression signal from the processor 16 to increase the hydraulic pressure of the hydraulic supply. In addition, the motor drive circuit 14 may control the motor drive current in response to a decompression signal from the processor 16 to decrease the hydraulic pressure of the hydraulic supply.

[0080] The motor drive circuit 14 may include an inverter circuit or an H-bridge circuit for controlling the motor drive current to be supplied to the motor 30. The inverter circuit or the H-bridge circuit may include a plurality of transistors that are turned on / off in response to a control signal from the processor 16.

[0081] The power circuit 15 may receive raw power from an external power source and convert the voltage of the raw power. The power circuit 15 may supply the converted voltage to the pedal sensor 11, the ultraviolet sensor 12, the valve drive circuit 13, the motor drive circuit 14, and / or the processor 16.

[0082] The power circuit 15 can convert the raw power into power with multiple different voltages. For example, the power circuit 15 can convert the voltage of the raw power into a first voltage suitable for the pedal sensor 11, the ultraviolet sensor 12, and / or the processor 16, and can also convert the voltage of the raw power into a second voltage suitable for the valve drive circuit 13 and / or the motor drive circuit 14.

[0083] For example, the power circuit 15 can include at least one DC - DC converter or at least one regulator. The DC - DC converter can include at least one inductor and at least one capacitor. The regulator can include a breakdown diode.

[0084] In addition, the power circuit 15 can be controlled by a control signal from the processor 16. For example, the power circuit 15 can block the reception of the raw power according to the control signal from the processor 16, or block the power to be supplied to the valve drive circuit 13 and / or the motor drive circuit 14 according to the control signal from the processor 16.

[0085] The processor 16 can receive the pedal signal of the pedal sensor 11 and the ultraviolet detection signal of the ultraviolet sensor 12, provide a valve control signal to the valve drive circuit 13, provide a motor control signal to the motor drive circuit 14, and provide a power control signal to the power circuit 15.

[0086] The processor 16 can provide a valve control signal and a motor control signal to the valve drive circuit 13 and the motor drive circuit 14 respectively based on the pedal signal of the pedal sensor 11. For example, the processor 16 can provide a valve control signal and a motor control signal to the valve drive circuit 13 and the motor drive circuit 14 respectively to supply hydraulic pressure to the wheel cylinder based on the pedal sensor 11 corresponding to the driver's intention to start braking. In addition, the processor 16 can provide a valve control signal and a motor control signal to the valve drive circuit 13 and the motor drive circuit 14 respectively to retract the hydraulic pressure of the wheel cylinder based on the pedal sensor 11 corresponding to the driver's intention to stop braking.

[0087] The processor 16 can provide a power control signal to the power circuit 15 based on the ultraviolet detection signal of the ultraviolet sensor 12. For example, the processor 16 can control the power circuit 15 to block the reception of power from an external power source in response to the ultraviolet detection signal of the first ultraviolet sensor 610 installed around the power receiving terminal. In addition, the processor 16 can control the power circuit 15 to block the power supply to the valve 20 and / or the motor 30 in response to the ultraviolet detection signal of the second ultraviolet sensor 620 installed around the power terminal. According to another example, the processor 16 can provide a warning message to the driver through the vehicle's display or speaker in response to the ultraviolet detection signal of the first ultraviolet sensor 610 installed around the power receiving terminal.

[0088] As described above, the electronic control device 10 can detect sparks and / or arcs occurring inside the electronic control device 10 through the ultraviolet sensor 12, and control the power to be supplied to the electronic control device 10 based on the detection of the sparks and / or arcs. In addition, the electronic control device 10 can provide a warning message to the driver through the vehicle's display or speaker based on the detection of the sparks and / or arcs. Therefore, it is possible to prevent a fire caused by the sparks and / or arcs from spreading from the electronic control device 10 to other components of the vehicle.

Figure 4 is an exploded perspective view of an electronic control device and a valve shown in one direction according to an embodiment. Figure 5 is an exploded perspective view of an electronic control device and a valve shown in another direction according to an embodiment.

[0090] As Figure 3 , Figure 4 and Figure 5 shown, the electronic control device 10 and a plurality of valves 20 can be provided.

[0091] The electronic control device 10 may include a housing 100, a cover 200, a first printed circuit board 300, and a second printed circuit board 400. Figure 3 , Figure 4 and Figure 5 shown, the housing 100, the cover 200, and the second printed circuit board 400 may not be essential components of the electronic control device 10, and at least some of the housing 100, the cover 200, and the second printed circuit board 400 may be omitted.

[0092] The housing 100 can form the appearance of the electronic control device 10 together with the cover 200, and protect the first printed circuit board 300 and the second printed circuit board 400 from external influences. In particular, the housing 100 can seal the internal space together with the cover 200 from external influences, and thus, it is possible to prevent external foreign substances such as moisture from entering the electronic control device 10.

In other words, the two terminals of each of the plurality of valve coils 21 may extend from the placement space 120 of the housing 100 to the accommodation space 110 of the housing 100.

[0098] In one side of the housing 100, a connection hole 150 may be formed to connect the accommodation space 110 to the outside of the housing 100. In the connection hole 150, a first connector 310 for receiving power from an external power source and connecting to a communication network for the vehicle may be provided.

[0099] The first connector 310 may include a power pin 311 and a ground pin 312 for receiving power from an external power source, and further includes a communication pin 313 for connecting to a communication network for the vehicle.

In addition, a current of the original power may flow in through the power pin 311 and flow out through the ground pin 312. The power pin 311 and the ground pin 312 may be insulated by air.

[0100] The cover 200 may seal the accommodation space 110 of the housing 100 in which the first printed circuit board 300 and the second printed circuit board 400 are accommodated.Figure 4 and Figure 5 The accommodation space 110 may be provided in the lower part of the housing 100, and the cover 200 may be provided below the housing 100 to enclose the accommodation space 110 that is opened from below.

[0101] As Figure 4 and Figure 5 shown in, the cover 200 may be hooked to the housing 100, but is not limited thereto. For example, the cover 200 may be coupled to the housing 100 by screws, or the cover 200 may be assembled into the housing 100.

[0102] The second printed circuit board 400 may be provided in the second hollow portion 140 of the housing 100 and exposed to the outside through the second hollow portion 140.

For example, the plurality of switch devices 340 may constitute an inverter circuit or an H-bridge circuit.

[0112] The first printed circuit board 300 may be provided with a second connector 320 for supplying a motor driving current to the motor 30. The second connector 320 may be connected to a plurality of terminals of the motor 30.

[0113] The ultraviolet sensor 12 for detecting UV-C emitted by a spark or an arc may be mounted on the first printed circuit board 300. The ultraviolet sensor 12 may detect UV-C and output an ultraviolet detection signal to the processor 16 in response to the detection of UV-C.

[0114] The ultraviolet sensor 12 may include a first ultraviolet sensor 610 and a second ultraviolet sensor 620 mounted on the first surface 301 of the first printed circuit board 300, and a third ultraviolet sensor 630 and a fourth ultraviolet sensor 640 mounted on the second surface 302 of the first printed circuit board 300. The first ultraviolet sensor 610, the second ultraviolet sensor 620, the third ultraviolet sensor 630, and the fourth ultraviolet sensor 640 may have the same structure and function, and be positioned at different positions.

[0115] Hereinafter, an example of the structure of the ultraviolet sensor 12 will be described.

[0116] Figure 6 An example of an ultraviolet sensor included in the electronic control device according to the embodiment is shown. Figure 7A , Figure 7B and Figure 7C A structure of an ultraviolet sensor included in an electronic control device according to an embodiment is shown.

[0117] As shown Figure 6 and Figure 7A as shown in FIGS. 1 and 2, the ultraviolet sensor 12 may include a photodiode 510, a sensor substrate 520, a lower connection terminal 530, and side walls 540.

[0118] The photodiode 510 may absorb ultraviolet light, particularly UV-C having a wavelength range of about 100 nm to about 280 nm, and output an electrical signal (e.g., a voltage signal or a current signal) in response to the absorption of UV-C. As described above, the photodiode 510 may be made of a semiconductor material capable of absorbing, for example, UV-C. For example, the photodiode 510 may include a PN junction diode made of gallium oxide (Ga2O3), gallium nitride (GaN), silicon carbide (SiC), or diamond (C).

[0119] The sensor substrate 520 may support the photodiode 510. Referring to Figure 7A FIG. 3, the photodiode 510 may be disposed on the upper surface 521 of the sensor substrate 520. Further, referring to Figure 7A FIG. 4, the lower connection terminal 530 may be formed on the lower surface 522 of the sensor substrate 520.

[0120] The sensor substrate 520 may electrically connect the photodiode 510 to the lower connection terminal 530. For example, the sensor substrate 520 may be made of a non-conductive material and include conductive signal lines extending from the photodiode 510 to the lower connection terminal 530. Power may be supplied to the photodiode 510 from the lower connection terminal 530 through the conductive signal lines, and an ultraviolet detection signal may be transmitted from the photodiode 510 to the lower connection terminal 530 through the conductive signal lines.

[0121] The lower connection terminal 530 may be disposed on the lower surface 522 opposite to the upper surface of the sensor substrate 520 on which the photodiode 510 is disposed.

[0122] The lower connection terminal 530 may be electrically connected to the photodiode 510 through the conductive signal lines of the sensor substrate 520. Depending on the installation of the ultraviolet sensor 12 on the first printed circuit board 300, the lower connection terminal 530 may be electrically connected to the first printed circuit board 300. Thus, the photodiode 510 may be electrically connected to the first printed circuit board 300 through the lower connection terminal 530 and electrically connected to the processor 16 through the first printed circuit board 300.

[0123] Therefore, since the lower connection terminal 530 is disposed on the lower surface 522 of the sensor substrate 520, the photodiode 510 of the ultraviolet sensor 12 mounted on the first printed circuit board 300 may face upward from the first printed circuit board 300.

[0124] The side wall 540 can be disposed at the side surface of the sensor substrate 520. The side wall 540 can have a cylindrical shape or a polygonal column shape. The side wall 540 can surround the photodiode 510 and protect the photodiode 510 from external foreign matters or external forces. The side wall 540 can be integrated into the sensor substrate 520.

[0125] Referring Figure 7A , an opening 550 through which ultraviolet light reaches the photodiode 510 can be formed in the upper side of the ultraviolet sensor 12. The ultraviolet light can irradiate the photodiode 510 through the opening 550. The opening 550 can be aligned with the photodiode 510 in the same direction with respect to the sensor substrate 520. Therefore, according to the installation of the ultraviolet sensor 12 on the first printed circuit board 300, the opening 550 and the photodiode 510 can face upward from the first printed circuit board 300. In addition, the ultraviolet light generated above the first printed circuit board 300 can irradiate the photodiode 510 through the opening 550.

[0126] The structure of the ultraviolet sensor 12 is not limited to Figure 7A the structure shown therein.

[0127] As Figure 7B shown, the ultraviolet sensor 12 can include a photodiode 510, a sensor substrate 520, a lower connection terminal 530, a side wall 540, and a transparent cover 560.

[0128] The photodiode 510, the sensor substrate 520, the lower connection terminal 530, and the side wall 540 can be the same as the photodiode, the sensor substrate, the lower connection terminal, and the side wall described with reference to Figure 7A the description.

[0129] Referring Figure 7B , the transparent cover 560 can be disposed on the upper surface of the ultraviolet sensor 12. The transparent cover 560 can cover the opening 550 of the ultraviolet sensor 12 from above. The transparent cover 560 can protect the photodiode 510 from external foreign matters or external forces, and the transparent cover 560 can also allow the ultraviolet light to reach the photodiode 510. For example, the transparent cover 560 can be made of a sapphire plate.

[0130] As Figure 7C shown, the ultraviolet sensor 12 can include a photodiode 510, a sensor substrate 520, a lower connection terminal 530, and a transparent dome 570.

[0131] The sensor substrate 520 and the lower connection terminal 530 can be the same as the sensor substrate and the lower connection terminal described with reference to Figure 7A the description.

[0132] The transparent dome 570 may cover the photodiode 510. The transparent dome 570 may prevent or suppress damage to the photodiode 510 due to an external mechanical action and / or damage to the photodiode 510 due to a chemical action.

[0133] The transparent dome 570 may be made of silicon or epoxy resin. For example, molten silicon or molten epoxy resin may be discharged onto the photodiode 510 through a nozzle or the like, and the discharged silicon or epoxy resin may be hardened to form the transparent dome 570.

[0134] Hereinafter, an example of the structure of the ultraviolet sensor 12 will be described.

[0135] Figure 8A , Figure 8B and Figure 8C A structure of an ultraviolet sensor included in an electronic control device according to an embodiment is shown.

[0136] like Figure 8A As shown in FIG. 1 , the ultraviolet sensor 12 may include a photodiode 510, a sensor substrate 520, a lower connection terminal 530, and a side wall 540. The sensor substrate 520, the lower connection terminal 530, and the side wall 540 may be connected to the reference Figure 7A The sensor substrate, lower connection terminals and side walls described are identical.

[0137] The photodiode 510 may include an inclined surface 511. The photodiode 510 may absorb ultraviolet light through the inclined surface 511. Therefore, the photodiode 510 may detect ultraviolet light generated in a side direction of the ultraviolet sensor 12 through the inclined surface 511.

[0138] like Figure 8B As shown in FIG. 1 , the ultraviolet sensor 12 may include a photodiode 510, a sensor substrate 520, a lower connection terminal 530, a side wall 540, and a transparent cover 560. The sensor substrate 520, the lower connection terminal 530, the side wall 540, and the transparent cover 560 may be connected to the Figure 7B The sensor substrate, lower connecting terminals, side walls and transparent cover shown in are the same.

[0139] The photodiode 510 may include an inclined surface 511. The photodiode 510 may absorb ultraviolet light through the inclined surface 511. Therefore, the photodiode 510 may detect ultraviolet light generated in a side direction of the ultraviolet sensor 12 through the inclined surface 511.

[0140] like Figure 8CAs shown in the figure, the ultraviolet sensor 12 may include a photodiode 510, a sensor substrate 520, a lower connection terminal 530, and a transparent dome 570. The photodiode 510, the sensor substrate 520, the lower connection terminal 530, and the transparent dome 570 may be the same as the photodiode, the sensor substrate, the lower connection terminal, and the transparent dome shown in Figure 7C the figure.

[0141] Through the transparent dome 570, the ultraviolet light generated in the lateral direction of the ultraviolet sensor 12 may reach the photodiode 510 by passing through the transparent dome 570. In order to absorb the ultraviolet light passing through the transparent dome 570 along the lateral direction, the photodiode 510 may include an inclined surface 511. The photodiode 510 may detect the ultraviolet light generated in the lateral direction of the ultraviolet sensor through the inclined surface 511. Figure 8C

[0142] Hereinafter, an example of the structure of the ultraviolet sensor 12 will be described.

[0143] Figure 9A , Figure 9B and Figure 9C show the structure of the ultraviolet sensor included in the electronic control device according to an embodiment.

[0144] As Figure 9A shown in the figure, the ultraviolet sensor 12 may include a photodiode 510, a sensor substrate 520, a side connection terminal 580, and a side wall 540.

[0145] The photodiode 510, the sensor substrate 520, and the side wall 540 may be the same as the photodiode, the sensor substrate, and the side wall shown in Figure 7A the figure.

[0146] The photodiode 510 may be disposed on the upper surface 521 of the sensor substrate 520, and the side connection terminal 580 may be disposed on the side surface of the sensor substrate 520. In addition, the side connection terminal 580 may be disposed on the side wall of the side wall 540 integrated into the sensor substrate 520.

[0147] The side connection terminal 580 may be electrically connected to the photodiode 510 through the conductive signal line of the sensor substrate 520. In addition, according to the installation of the ultraviolet sensor 12 on the first printed circuit board 300, the side connection terminal 580 may be electrically connected to the first printed circuit board 300. Therefore, the photodiode 510 may be electrically connected to the processor 16 through the side connection terminal 580 and the first printed circuit board 300.

[0148] Therefore, since the side connection terminal 580 is provided on the side surface 523 of the sensor substrate 520, the photodiode 510 of the ultraviolet sensor 12 mounted on the first printed circuit board 300 can face the side direction of the first printed circuit board 300.

[0149] In addition, the opening 550 can be aligned with the photodiode 510 in the same direction with respect to the sensor substrate 520. Therefore, according to the mounting of the ultraviolet sensor 12 on the first printed circuit board 300, the opening 550 and the photodiode 510 can face the side direction of the first printed circuit board 300. In addition, the ultraviolet light generated on the first printed circuit board 300 can pass through the opening 550 and irradiate the photodiode 510.

[0150] As Figure 9B shown, the ultraviolet sensor 12 can include a photodiode 510, a sensor substrate 520, a side connection terminal 580, a side wall 540, and a transparent cover 560.

[0151] The photodiode 510, the sensor substrate 520, the side wall 540, and the transparent cover 560 can be the same as the photodiode, the sensor substrate, the side wall, and the transparent cover described Figure 7B therein.

[0152] The photodiode 510 can be provided on the upper surface 521 of the sensor substrate 520, and the side connection terminal 580 can be provided on the side surface 523 of the sensor substrate 520. In addition, the side connection terminal 580 can be provided on the side wall of the side wall 540 integrated into the sensor substrate 520.

[0153] Therefore, since the side connection terminal 580 is provided on the side surface 523 of the sensor substrate 520, the photodiode 510 of the ultraviolet sensor 12 mounted on the first printed circuit board 300 can face the side direction of the first printed circuit board 300. In addition, the ultraviolet light generated on the first printed circuit board 300 can irradiate the photodiode 510.

[0154] As Figure 9C shown, the ultraviolet sensor 12 can include a photodiode 510, a sensor substrate 520, a side connection terminal 580, and a transparent dome 570.

[0155] The photodiode 510, the sensor substrate 520, and the transparent dome 570 can be the same as the photodiode, the sensor substrate, and the transparent dome described with reference to Figure 7C therein.

[0156] The photodiode 510 can be provided on the upper surface 521 of the sensor substrate 520, and the side connection terminal 580 can be provided on the side surface 523 of the sensor substrate 520.

[0157] Therefore, since the side connection terminal 580 is provided on the side surface 523 of the sensor substrate 520, the photodiode 510 of the ultraviolet sensor 12 mounted on the first printed circuit board 300 can face the side direction of the first printed circuit board 300. In addition, the ultraviolet light generated on the first printed circuit board 300 can be irradiated onto the photodiode 510.

[0158] Hereinafter, an example of the structure of the ultraviolet sensor 12 will be described.

[0159] Figure 10A 、 Figure 10B and Figure 10C shows the structure of the ultraviolet sensor included in the electronic control device according to the embodiment.

[0160] As Figure 10A shown, the ultraviolet sensor 12 may include a photodiode 510, a sensor substrate 520, a side connection terminal 580, and a side wall 540. The sensor substrate 520, the side connection terminal 580, and the side wall 540 may be the same as the sensor substrate, the side connection terminal, and the side wall shown Figure 9A therein. In addition, the photodiode 510 may include an inclined surface 511, and the ultraviolet light is absorbed through the inclined surface 511.

[0161] As Figure 10B shown, the ultraviolet sensor 12 may include a photodiode 510, a sensor substrate 520, a side connection terminal 580, a side wall 540, and a transparent cover 560. The sensor substrate 520, the side connection terminal 580, the side wall 540, and the transparent cover 560 may be the same as the sensor substrate, the side connection terminal, the side wall, and the transparent cover shown Figure 9B therein. In addition, the photodiode 510 may include an inclined surface 511, and the ultraviolet light is absorbed through the inclined surface 511.

[0162] As Figure 10C shown, the ultraviolet sensor 12 may include a photodiode 510, a sensor substrate 520, a side connection terminal 580, and a transparent dome 570. The sensor substrate 520, the side connection terminal 580, and the transparent dome 570 may be the same as the sensor substrate, the side connection terminal, and the transparent dome shown Figure 9C therein. In addition, the photodiode 510 may include an inclined surface 511, and the ultraviolet light is absorbed through the inclined surface 511.

[0163] Hereinafter, an example of the structure of the ultraviolet sensor 12 will be described.

[0164] Figure 11A and Figure 11BShows the structure of an ultraviolet sensor included in an electronic control device according to an embodiment.

[0165] As Figure 11A shown, the ultraviolet sensor 12 may include a photodiode 510, a sensor substrate 520, a lower connection terminal 530, and a side wall 540.

[0166] The photodiode 510, the sensor substrate 520, and the lower connection terminal 530 may be the same as the photodiode, the sensor substrate, and the lower connection terminal Figure 7A shown.

[0167] The side wall 540 may be provided at a part of the side surface of the sensor substrate 520, and a side opening 552 may be formed in at least a part of the side surface of the sensor substrate 520. In other words, an upper opening 551 may be formed above the photodiode 510, and the side opening 552 may be formed toward the side surface of the photodiode 510.

[0168] Therefore, since the side opening 552 is formed toward at least a part of the side surface of the sensor substrate 520, the ultraviolet light generated on the first printed circuit board 300 may pass through the side opening 552 of the side surface and irradiate the photodiode 510.

[0169] As Figure 11B shown, the ultraviolet sensor 12 may include a photodiode 510, a sensor substrate 520, a lower connection terminal 530, a side wall 540, and a transparent cover 560.

[0170] The photodiode 510, the sensor substrate 520, and the lower connection terminal 530 may be the same as the photodiode, the sensor substrate, and the lower connection terminal Figure 7B described with reference to.

[0171] The side wall 540 may be provided at a part of the side surface of the sensor substrate 520, and a side transparent cover 562 may be provided toward at least a part of the side surface of the sensor substrate 520. An upper transparent cover 561 may be provided above the photodiode 510, and the side transparent cover 562 may be provided toward the side surface of the photodiode 510.

[0172] Therefore, since the side transparent cover 562 is provided toward at least a part of the side surface of the sensor substrate 520, the ultraviolet light generated on the first printed circuit board 300 may pass through the side transparent cover 562 of the side surface and irradiate the photodiode 510.

[0173] Hereinafter, an example of the structure of the ultraviolet sensor 12 will be described.

[0174] Figure 12A And Figure 12BShows the structure of an ultraviolet sensor included in an electronic control device according to an embodiment.

[0175] As Figure 12A shown, the ultraviolet sensor 12 may include a photodiode 510, a sensor substrate 520, a lower connection terminal 530, and a side wall 540. The sensor substrate 520, the lower connection terminal 530, and the side wall 540 may be the same as the sensor substrate, the lower connection terminal, and the side wall shown Figure 11A therein. In addition, the photodiode 510 may include an inclined surface 511, and absorb ultraviolet light through the inclined surface 511.

[0176] As Figure 12B shown, the ultraviolet sensor 12 may include a photodiode 510, a sensor substrate 520, a lower connection terminal 530, a side wall 540, and a transparent cover 560. The sensor substrate 520, the lower connection terminal 530, the side wall 540, and the transparent cover 560 may be the same as the sensor substrate, the lower connection terminal, the side wall, and the transparent cover described with reference to Figure 11B therein. In addition, the photodiode 510 may include an inclined surface 511, and absorb ultraviolet light through the inclined surface 511.

[0177] Hereinafter, an example of the position of the ultraviolet sensor 12 will be described.

[0178] Figure 13 Shows the first surface of the first printed circuit board included in an electronic control device according to an embodiment. Figure 14 Shows the second surface of the first printed circuit board included in an electronic control device according to an embodiment.

[0179] As described above, the ultraviolet sensor 12 may include a first ultraviolet sensor 610 and a second ultraviolet sensor 620 mounted on the first surface 301 of the first printed circuit board 300, and a third ultraviolet sensor 630 and a fourth ultraviolet sensor 640 mounted on the second surface 302 of the first printed circuit board 300. The first ultraviolet sensor 610, the second ultraviolet sensor 620, the third ultraviolet sensor 630, and the fourth ultraviolet sensor 640 may have the same structure and function, and different positions.

[0180] As Figure 13 shown, the first ultraviolet sensor 610 may be disposed around the first connector 310 on the first surface 301 of the first printed circuit board 300.

[0181] The raw power supplied to the electronic control device 10 can be provided to the power circuit 15 through the first connector 310. The first connector 310 may also include power pins 311 for receiving power from an external power source and ground pins 312, and may also include communication pins 313 for connecting to a vehicle communication network.

[0182] A voltage of the raw power can be applied between the power pin 311 and the ground pin 312, and the current of the raw power can flow in through the power pin 311 and flow out through the ground pin 312.

[0183] In this case, due to the sudden supply of the raw power, the sudden increase in the voltage of the raw power, or the sudden increase in the current of the raw power, the insulation between the power pin 311 and the ground pin 312, between the power pin 311 and the communication pin 313, or between the power pin 311 and the first printed circuit board 300 may break down. A very strong electric field may be generated between the power pin 311 and the ground pin 312, between the power pin 311 and the communication pin 313, or between the power pin 311 and the first printed circuit board 300, and due to this very strong magnetic field, a direct movement of charges may occur between the power pin 311 and the ground pin 312, between the power pin 311 and the communication pin 313, or between the power pin 311 and the first printed circuit board 300. Due to the movement of charges between the power pin 311 and the ground pin 312, between the power pin 311 and the communication pin 313, or between the power pin 311 and the first printed circuit board 300, sparks or arcs may occur. The above description of the occurrence of sparks or arcs is only an example, and for various reasons, sparks or arcs may occur between the power pin 311 and the ground pin 312, between the power pin 311 and the communication pin 313, between the ground pin 312 and the communication pin 313, between the power pin 311 and the first printed circuit board 300, or between the ground pin 312 and the first printed circuit board 300.

[0184] Therefore, for various reasons, sparks or arcs may occur in the first connector 310 on the first surface 301, and the sparks or arcs may include the emission of UV-C.

[0185] The first ultraviolet sensor 610 may be positioned around the first connector 310 on the first surface 301 to stably detect UV-C generated by a spark or an arc. For example, the first ultraviolet sensor 610 may be an electrical / electronic device positioned closest to the first connector 310 on the first surface 301. According to another example, the shortest distance between the first ultraviolet sensor 610 and the first connector 310 on the first surface 301 may be less than the maximum distance between the pins 311, 312, and 313 that make up the first connector 310. According to another embodiment, the shortest distance between the first ultraviolet sensor 610 and the first connector 310 on the first surface 301 may be less than the minimum distance between the two ends of the first printed circuit board 300. According to another example, the shortest distance between the first ultraviolet sensor 610 and the first connector 310 on the first surface 301 may be less than half of the maximum distance between the two ends of the first printed circuit board 300.

[0186] In addition, the first ultraviolet sensor 610 may be positioned such that the opening 550 of the first ultraviolet sensor 610 faces the first connector 310. Thus, the UV-C generated in the first connector 310 may pass through the opening 550 of the first ultraviolet sensor 610 and irradiate the photodiode 510.

[0187] As Figure 13 shown, the second ultraviolet sensor 620 may be positioned around the second connector 320 on the first surface 301 of the first printed circuit board 300.

[0188] The motor drive power of the motor drive circuit 14 may be supplied to the motor 30 through the second connector 320. The second connector 320 may include a U-phase pin 321, a V-phase pin 322, and a W-phase pin 323 for supplying motor drive current to the motor 30.

[0189] A voltage of the motor drive power may be applied between at least 17 pins among the U-phase pin 321, the V-phase pin 322, and the W-phase pin 323. In addition, the current of the motor drive power may flow into the motor 30 through at least one of the U-phase pin 321, the V-phase pin 322, and the W-phase pin 323, and flow out of the motor 30 through at least one of the U-phase pin 321, the V-phase pin 322, and the W-phase pin 323.

[0190] In this case, even when the motor drive circuit 14 is suddenly turned off, due to inertia, the motor 30 can continue to rotate without stopping immediately. By the rotation of the motor 30, an electromotive force can be generated in the coil included in the motor 30, and the electromotive force can be applied between at least 17 of the U-phase pin 321, the V-phase pin 322, and the W-phase pin 323. Due to the electromotive force of the motor 30, the insulation between at least 17 of the U-phase pin 321, the V-phase pin 322, and the W-phase pin 323 may break down. Due to the electromotive force of the motor 30, a very strong electric field may be generated between at least 17 of the U-phase pin 321, the V-phase pin 322, and the W-phase pin 323, and due to this very strong electric field, a direct movement of charges may occur between at least 17 of the U-phase pin 321, the V-phase pin 322, and the W-phase pin 323. The movement of charges between at least 17 of the U-phase pin 321, the V-phase pin 322, and the W-phase pin 323 may cause a spark or an arc. The above description of the occurrence of a spark or an arc is only an example, and due to various reasons, a spark or an arc may occur between the U-phase pin 321, the V-phase pin 322, and the W-phase pin 323.

[0191] Therefore, due to various reasons, a spark or an arc may occur in the second connector 320 on the first surface 301, and the spark or an arc may include the emission of UV-C.

[0192] The second ultraviolet sensor 620 can be positioned around the second connector 320 on the first surface 301 to stably detect the UV-C generated by the spark or the arc. For example, the second ultraviolet sensor 620 can be an electrical / electronic device positioned on the first surface 301 closest to the second connector 320. According to another example, the shortest distance between the second ultraviolet sensor 620 and the second connector 320 on the first surface 301 can be less than the maximum distance between the U-phase pin 321, the V-phase pin 322, and the W-phase pin 323 that make up the second connector 320. According to another example, the shortest distance between the second ultraviolet sensor 620 and the second connector 320 on the first surface 301 can be less than the minimum distance between the two ends of the first printed circuit board 300. According to another example, the shortest distance between the second ultraviolet sensor 620 and the second connector 320 on the first surface 301 can be less than half of the maximum distance between the two ends of the first printed circuit board 300.

[0193] In addition, the second ultraviolet sensor 620 can be positioned such that the opening 550 of the second ultraviolet sensor 620 faces the second connector 320. Therefore, the UV-C generated in the second connector 320 can pass through the opening 550 of the second ultraviolet sensor 620 and irradiate the photodiode 510.

[0194] As Figure 14 shown, the third ultraviolet sensor 630 may be positioned around the first connector 310 on the second surface 302 of the first printed circuit board 300.

[0195] As described above, since the same situation of spark or arc occurring in the first connector 310 on the first surface 301 may occur in the first connector 310 on the second surface 302, and the spark or arc may include the emission of UV-C.

[0196] The third ultraviolet sensor 630 may be positioned around the first connector 310 on the second surface 302 to stably detect the UV-C caused by the spark or arc. For example, the third ultraviolet sensor 630 may be an electrical / electronic device positioned closest to the first connector 310 on the second surface 302. According to another example, the shortest distance between the third ultraviolet sensor 630 and the first connector 310 on the second surface 302 may be less than the maximum distance between the pins 311, 312, and 313 constituting the first connector 310. According to another example, the shortest distance between the third ultraviolet sensor 630 and the first connector 310 on the second surface 302 may be less than the minimum distance between the two ends of the first printed circuit board 300. According to another embodiment, the shortest distance between the third ultraviolet sensor 630 and the first connector 310 on the second surface 302 may be less than half of the maximum distance between the two ends of the first printed circuit board 300.

[0197] In addition, the third ultraviolet sensor 630 may be positioned such that the opening 550 of the third ultraviolet sensor 630 faces the first connector 310. Therefore, the UV-C generated in the first connector 310 may pass through the opening 550 of the third ultraviolet sensor 630 and irradiate the photodiode 510.

[0198] As Figure 14 shown, the fourth ultraviolet sensor 640 may be positioned around the second connector 320 on the second surface 302 of the first printed circuit board 300.

[0199] As described above, since the same situation of spark or arc occurring in the second connector 320 on the first surface 301 may occur in the second connector 320 on the second surface 302, and the spark or arc may include the emission of UV-C.

[0200] The fourth ultraviolet sensor 640 may be positioned around the second connector 320 on the second surface 302 to stably detect UV-C generated by a spark or an arc. For example, the fourth ultraviolet sensor 640 may be an electrical / electronic device positioned on the second surface 302 closest to the second connector 320. According to another example, the shortest distance between the fourth ultraviolet sensor 640 and the second connector 320 on the second surface 302 may be less than the maximum distance between the U-phase pin 321, the V-phase pin 322, and the W-phase pin 323 that constitute the second connector 320. According to another example, the shortest distance between the fourth ultraviolet sensor 640 and the second connector 320 on the second surface 302 may be less than the minimum distance between the two ends of the first printed circuit board 300. According to another example, the shortest distance between the fourth ultraviolet sensor 640 and the second connector 320 on the second surface 302 may be less than half of the maximum distance between the two ends of the first printed circuit board 300.

[0201] In addition, the fourth ultraviolet sensor 640 may be positioned such that the opening 550 of the fourth ultraviolet sensor 640 faces the second connector 320. Thus, the UV-C generated in the second connector 320 may pass through the opening 550 of the fourth ultraviolet sensor 640 and irradiate the photodiode 510.

[0202] Hereinafter, examples of the positions of the ultraviolet sensors 12 will be described.

[0203] Figure 15 The first surface of the first printed circuit board included in the electronic control device according to the embodiment is shown. Figure 16 The second surface of the first printed circuit board included in the electronic control device according to the embodiment is shown.

[0204] As Figure 15 shown, the first ultraviolet sensor 610 may be positioned around the first corner 301a on the first surface 301 of the first printed circuit board 300. For example, the first ultraviolet sensor 610 may be an electrical / electronic device positioned on the first surface 301 closest to the first corner 301a.

[0205] The first ultraviolet sensor 610 may be positioned around the first corner 301a such that the opening 550 of the first ultraviolet sensor 610 faces the first connector 310. Thus, the UV-C generated in the first connector 310 may pass through the opening 550 of the first ultraviolet sensor 610 and irradiate the photodiode 510.

[0206] In addition, the first ultraviolet sensor 610 can be positioned around the first corner 301a such that the opening 550 of the first ultraviolet sensor 610 faces the substantially central portion of the first printed circuit board 300. Accordingly, the first ultraviolet sensor 610 can detect the UV-C generated from components mounted on the first surface 301 of the first printed circuit board 300.

[0207] As Figure 15 shown, the second ultraviolet sensor 620 can be positioned on the first surface 301 of the first printed circuit board 300 around the second corner 301b. For example, the second ultraviolet sensor 620 can be an electrical / electronic device positioned on the first surface 301 closest to the second corner 301b.

[0208] The second ultraviolet sensor 620 can be positioned around the second corner 301b such that the opening 550 of the second ultraviolet sensor 620 faces the second connector 320. Accordingly, the UV-C generated in the second connector 320 can pass through the opening 550 of the second ultraviolet sensor 620 and irradiate the photodiode 510.

[0209] In addition, the second ultraviolet sensor 620 can be positioned around the second corner 301b such that the opening 550 of the second ultraviolet sensor 620 faces the substantially central portion of the first printed circuit board 300. Accordingly, the second ultraviolet sensor 620 can detect the UV-C generated from components mounted on the first surface 301 of the first printed circuit board 300.

[0210] As Figure 16 shown, the third ultraviolet sensor 630 can be positioned on the second surface 302 of the first printed circuit board 300 around the third corner 302a. For example, the third ultraviolet sensor 630 can be an electrical / electronic device positioned on the second surface 302 closest to the third corner 302a.

[0211] In addition, the third ultraviolet sensor 630 can be positioned around the third corner 302a such that the opening 550 of the third ultraviolet sensor 630 faces the first connector 310. Accordingly, the UV-C generated in the first connector 310 can pass through the opening 550 of the third ultraviolet sensor 630 and irradiate the photodiode 510.

[0212] In addition, the third ultraviolet sensor 630 can be positioned around the third corner 302a such that the opening 550 of the third ultraviolet sensor 630 faces the substantially central portion of the first printed circuit board 300. Accordingly, the third ultraviolet sensor 630 can detect the UV-C generated from components mounted on the second surface 302 of the first printed circuit board 300.

[0213] As Figure 16 shown, the fourth ultraviolet sensor 640 may be positioned around the fourth corner 302b on the second surface 302 of the first printed circuit board 300. For example, the fourth ultraviolet sensor 640 may be an electrical / electronic device positioned on the second surface 302 closest to the fourth corner 302b.

[0214] The fourth ultraviolet sensor 640 may be positioned around the fourth corner 302b such that the opening 550 of the fourth ultraviolet sensor 640 faces the second connector 320. Thus, the UV-C generated in the second connector 320 may pass through the opening 550 of the fourth ultraviolet sensor 640 and irradiate the photodiode 510.

[0215] In addition, the fourth ultraviolet sensor 640 may be positioned around the fourth corner 302b such that the opening 550 of the fourth ultraviolet sensor 640 faces a substantially central portion of the first printed circuit board 300. Thus, the fourth ultraviolet sensor 640 may detect the UV-C generated from components mounted on the second surface 302 of the first printed circuit board 300.

[0216] So far, the cases where the ultraviolet sensor 12 is positioned around the corners 301a, 301b, 302a, and 302b of the first printed circuit board 300 have been described. However, the position of the ultraviolet sensor 12 is not limited to Figure 15 or Figure 16 the positions shown. For example, the ultraviolet sensor 12 may be provided at an edge region of the first printed circuit board 300. Thus, the ultraviolet sensor 12 may detect the UV-C generated from components mounted on the first surface 301 or the second surface 302 of the first printed circuit board 300.

[0217] So far, the embodiments in which the ultraviolet sensor 12 is positioned on the first printed circuit board 300 on which the first connector 310 and the second connector 320 are mounted have been described.

[0218] The position of the ultraviolet sensor 12 is not limited thereto. For example, the ultraviolet sensor 12 may be positioned on a third printed circuit board different from the first printed circuit board 300. The sensor module including the ultraviolet sensor 12 and the third printed circuit board is referred to as an "ultraviolet sensor module".

[0219] Figure 17 An example of the circuit configuration of the ultraviolet sensor module included in the electronic control device according to the embodiment is shown.

[0220] As Figure 17As shown in [the figure], the ultraviolet sensor module 700 may include a photodiode 510, an amplifier 701, a capacitor 702, and / or a resistor 703. Figure 17 The photodiode 510, the amplifier 701, the capacitor 702, and / or the resistor 703 shown in [the figure] may be mounted on a third printed circuit board. Figure 17 The amplifier 701, the capacitor 702, and / or the resistor 703 shown in [the figure] may not correspond to the necessary components of the ultraviolet sensor 12, and the amplifier 701, the capacitor 702, and / or the resistor 703 may be omitted.

[0221] The photodiode 510 may include an anode and a cathode, and allow an external current to flow from the anode to the cathode, and block the external current from flowing from the cathode to the anode. In addition, the photodiode 510 may absorb ultraviolet light, especially UV-C, and generate a reverse current flowing from the cathode to the anode.

[0222] The amplifier 701 may include a positive input terminal, a negative input terminal, and an output terminal. Among them, the positive input terminal may be connected to the anode of the photodiode 510, and the negative input terminal may be connected to the cathode of the photodiode 510. The voltage of the output terminal of the amplifier 701 may correspond to the output signal (i.e., the ultraviolet detection signal) of the ultraviolet sensor 12.

[0223] The capacitor 702 and the resistor 703 may be connected in parallel with each other between the negative input terminal and the output terminal of the amplifier 701. The reverse current generated in the photodiode 510 may pass through the resistor 703, thereby generating a potential difference between both ends of the resistor 703. Therefore, the potential (i.e., voltage) of the output terminal of the amplifier 701 may increase.

[0224] Figure 18 An example of a first printed circuit board and an ultraviolet sensor module included in an electronic control device according to an embodiment is shown. Figure 19 An example of a first printed circuit board and an ultraviolet sensor module included in an electronic control device according to an embodiment is shown.

[0225] The ultraviolet sensor module 700 may include a third printed circuit board 710, a photodiode 510 mounted on the third printed circuit board 710, and other circuits 701, 702, and 703.

The third printed circuit board 710 may be electrically connected to the first printed circuit board 300 through a plurality of pins.

[0227] The third printed circuit board 710 may include a third surface 711 and a fourth surface 712. The third surface faces the first surface 301 of the first printed circuit board 300, and the fourth surface faces a direction opposite to the direction facing the first printed circuit board 300.

[0228] The photodiode 510 for detecting UV-C may be mounted on the third surface 711 of the third printed circuit board 710. Thus, the photodiode 510 may face the first surface 301 of the first printed circuit board 300. In other words, the photodiode 510 may face the first connector 310 and the second connector 320 provided on the first surface 301. Thus, the photodiode 510 may detect the UV-C generated by the spark or arc of the first connector 310 or the second connector 320.

[0229] As Figure 19 shown, the third printed circuit board 710 of the ultraviolet sensor module 700 may be positioned on the first surface 301 of the first printed circuit board 300 in a manner parallel to the first printed circuit board 300. The third printed circuit board 710 may be electrically connected to the first printed circuit board 300 through a plurality of pins.

[0230] The third printed circuit board 710 may include a third surface 711 and a fourth surface 712. The third surface is positioned on the first surface 301 of the first printed circuit board 300 facing the first connector 310, and the fourth surface is positioned facing the second connector 320.

[0231] The photodiode 510 may be mounted on the third surface 711 and the fourth surface 712 of the third printed circuit board 710. Thus, the photodiode 510 mounted on the third surface 711 may face the first connector 310 positioned on the first surface 301 of the first printed circuit board 300, and the photodiode 510 mounted on the fourth surface 712 may face the second connector 320 positioned on the first surface 301 of the first printed circuit board 300. Thus, the photodiode 510 mounted on the third surface 711 may detect the UV-C generated by the spark or arc of the first connector 310 on the first surface 301 of the first printed circuit board 300, and the photodiode 510 mounted on the fourth surface 712 may detect the UV-C generated by the spark or arc of the second connector 320 on the first surface 301 of the first printed circuit board 300.

[0232] As described above, the ultraviolet sensor 12 or the ultraviolet sensor module 700 included in the electronic control device 10 may detect UV-C generated by a spark or an arc generated in the first printed circuit board 300. The electronic control device 10 may control the power to be supplied to the electronic control device 10 in response to the detection of UV-C by the ultraviolet sensor 12 or the ultraviolet sensor module 700, or provide a warning message to the driver through a display or a speaker of the vehicle.

[0233] Therefore, it is possible to prevent a fire caused by a spark and / or an arc from spreading from the electronic control device 10 to other components of the vehicle.

[0234] According to an aspect of the present disclosure, an electronic control device and a braking device capable of detecting an arc or a spark, which is a starting point of a fire occurring in an electrical / electronic device, may be provided. Therefore, it is possible to prevent, suppress, or minimize a fire occurring in the electronic control device and the braking device.

The instructions may be stored in the form of program code, and when executed by a processor, the instructions may create program modules to perform the operations of the disclosed embodiments. The recording medium may be implemented as a computer-readable recording medium.

[0236] The computer-readable recording medium may include various recording media storing instructions interpretable by a computer. For example, the computer-readable recording medium may include a read-only memory (ROM), a random access memory (RAM), a magnetic tape, a magnetic disk, a flash memory, an optical data storage device, and the like.

[0237] The computer-readable storage medium may be provided in the form of a non-transitory storage medium, where the term "non-transitory" simply means that the storage medium is a physical device and does not include signals (such as electromagnetic waves), but the term does not distinguish between a case where data is semi-permanently stored in the storage medium and a case where data is temporarily stored in the storage medium. For example, the "non-transitory storage medium" may include a buffer in which data is temporarily stored.
