[0003] [Patent Document 1] JP 2009-21486 A Summary of the Invention [Problem to be solved by the invention]

[0004] In recent control devices, it is sometimes desirable to add information on the traceability of an electronic circuit board (e.g., manufacturing time, manufacturing factory, etc.) to enable tracing of the manufacturing process of the electronic circuit board, etc. However, since an identifier tends to have a larger display area as the amount of information included increases, when an identifier including information on traceability is provided on an electronic circuit board as in Patent Document 1, for example, there is a risk that the electronic circuit board will become larger.

[0017] As shown in FIG. 1, motorcycle 1 comprises a body 2, a handlebar 3 rotatably mounted relative to body 2, a front wheel 4 rotatably mounted relative to body 2 together with handlebar 3, a rear wheel 5 rotatably mounted relative to body 2 and driven by a drive source (not shown, e.g., an engine, an electric motor, etc.), a front wheel disc rotor 4a that rotates together with front wheel 4, a rear wheel disc rotor 5a that rotates together with rear wheel 5, a brake system 100 that brakes front wheel 4 and rear wheel 5, and a brake fluid pressure control device 10 that controls brake system 100.

[0018] As shown in FIG. 2, the brake system 100 includes a first operator 6 and a second operator 7 operated by a rider, a front wheel braking mechanism 20 that brakes the front wheel 4, a rear wheel braking mechanism 30 that brakes the rear wheel 5, a front wheel friction member 25 that generates a friction force on the front wheel disc rotor 4a, a rear wheel friction member 35 that generates a friction force on the rear wheel disc rotor 5a, and a brake fluid pressure control device 10.

[0019] In this embodiment, the first operator 6 is, for example, a brake lever provided on the handlebar 3 and operated by the rider's hand. The second operator 7 is, for example, a brake pedal provided on the lower part of the body 2 and operated by the rider's foot.

[0020] 2, the front wheel braking mechanism 20 is composed of a first master cylinder 21 to which the motion of the first operating element 6 is transmitted, a first reservoir 22 of brake fluid attached to the first master cylinder 21, a first wheel cylinder 24 connected to the first master cylinder 21 via a first fluid passage 23 filled with brake fluid, a front wheel friction member 25 pressed against the front wheel disc rotor 4a by the hydraulic pressure of the brake fluid in the first wheel cylinder 24, and a brake hydraulic pressure control device 10 described later. The rear wheel braking mechanism 30 is composed of a second master cylinder 31 to which the motion of the second operating element 7 is transmitted, a second reservoir 32 of brake fluid attached to the second master cylinder 31, a second wheel cylinder 34 connected to the second master cylinder 31 via a second fluid passage 33 filled with brake fluid, a rear wheel friction member 35 pressed against the rear wheel disc rotor 5a by the hydraulic pressure of the brake fluid in the second wheel cylinder 34, and the brake hydraulic pressure control device 10. As described below, portions 23b, 23c, 33b, and 33c of the first fluid path 23 and the second fluid path 33 are formed as internal fluid paths in a base body 60 of the brake fluid pressure control device 10. The brake fluid pressure control device 10 is disposed, for example, in a body 2 of the motorcycle 1 (see FIG. 1).

[0021] The front wheel braking mechanism 20 is configured to press a front wheel friction member 25 against the front wheel disc rotor 4a in response to the amount of operation of the first operating element 6 to generate a friction force, and to generate a braking force on the front wheels 4 in response to the amount of operation of the first operating element 6. The rear wheel braking mechanism 30 is configured to press a rear wheel friction member 35 against the rear wheel disc rotor 5a in response to the amount of operation of the second operating element 7 to generate a friction force, and to generate a braking force on the rear wheels 5 in response to the amount of operation of the second operating element 7.

[0022] In this embodiment, the brake system 100 is configured to have a brake lever as the first operator 6 and a brake pedal as the second operator 7, but the brake system is not limited to this example and may, for example, be configured to have a brake pedal as the first operator and a brake lever as the second operator, or, for example, to have one or more brake levers as the first operator and the second operator, or, for example, to have one or more brake pedals as the first operator and the second operator.

[0023] In this embodiment, the front wheel braking mechanism 20 and the rear wheel braking mechanism 30 are configured to generate frictional force by pressing a friction member against the disc rotor, but the front wheel braking mechanism and the rear wheel braking mechanism may be configured to generate frictional force by, for example, pressing a friction member of a brake shoe against a brake drum that rotates together with the wheels, or may be configured to generate frictional force by pressing a friction member against the disc rotor or the brake drum by an actuator that is electrically connected to an operator and operated in response to the operation of the operator. Also, the brake system may be configured to include only one of the front wheel braking mechanism or the rear wheel braking mechanism.

[0024] <About the control device> The brake fluid pressure control device 10 as a control device will be described with reference to Figs. 2 to 5. The brake fluid pressure control device 10 includes first to fourth solenoid valves 40a to 40d, pumps 27, 37, a motor 50, etc. as a fluid pressure control mechanism that controls the fluid pressure of the brake fluid in the brake system 100. The first to fourth solenoid valves 40a to 40d and the motor 50 as the fluid pressure control mechanism are controlled between energized and non-energized states by a control board 70, and are configured to control the fluid pressure of the brake fluid in the brake system 100 by controlling their operation. The brake fluid pressure control device 10 of this embodiment can control the antilock operation of the front wheel 4 and the rear wheel 5 of the motorcycle 1 by controlling the operation of the fluid pressure control mechanism by the control board 70, as described later, and corresponds to a control device that controls the antilock brake operation of the vehicle brake system according to the present invention.

[0025] As shown in FIG. 2, the brake fluid pressure control device 10 includes a first main fluid path 23b connecting the first master cylinder 21 and the first wheel cylinder 24, a first solenoid valve 40a arranged in the first main fluid path 23b, a first sub-fluid path 23c branching off from a region of the first main fluid path 23b closer to the first wheel cylinder 24 than the first solenoid valve 40a and connected to a region of the first main fluid path 23b closer to the first master cylinder 21 than the first solenoid valve 40a, a second solenoid valve 40b arranged in the first sub-fluid path 23c, a first accumulator 26 arranged in a region of the first sub-fluid path 23c closer to the first master cylinder 21 than the second solenoid valve 40b and for temporarily storing brake fluid, and a first pump 27 arranged in a region of the first sub-fluid path 23c closer to the first master cylinder 21 than the first accumulator 26. The first main liquid path 23b and the first sub liquid path 23c constitute a part of the first liquid path 23 described above.

[0026] The brake fluid pressure control device 10 also includes a second main fluid path 33b connecting the second master cylinder 31 and the second wheel cylinder 34, a third solenoid valve 40c arranged in the second main fluid path 33b, a second sub-fluid path 33c branching off from a region of the second main fluid path 33b closer to the second wheel cylinder 34 than the third solenoid valve 40c and connected to a region of the second main fluid path 33b closer to the second master cylinder 31 than the third solenoid valve 40c, a fourth solenoid valve 40d arranged in the second sub-fluid path 33c, a second accumulator 36 arranged in a region of the second sub-fluid path 33c closer to the second master cylinder 31 than the fourth solenoid valve 40d and for temporarily storing brake fluid, and a second pump 37 arranged in a region of the second sub-fluid path 33c closer to the second master cylinder 31 than the second accumulator 36. The second main liquid path 33b and the second sub liquid path 33c constitute a part of the second liquid path 33 described above.

[0027] The first to fourth solenoid valves 40a to 40d are controlled such that the first to fourth valve bodies 41a to 41d corresponding to each coil open or close each fluid path by controlling the first to fourth coils 42a to 42d (see FIG. 4) corresponding to each solenoid valve to an energized or de-energized state by the control board 70. The first to fourth solenoid valves 40a to 40d correspond to a fluid pressure control mechanism for controlling the hydraulic pressure of the brake fluid of the present invention.

[0028] The first pump 27 pumps up the brake fluid stored in the first accumulator 26 and outputs it toward the first main fluid path 23b. The second pump 37 pumps up the brake fluid stored in the second accumulator 36 and outputs it toward the second main fluid path 33b. The first pump 27 and the second pump 37 are driven by a common electric motor 50. The motor 50 has its operation (stopped state and rotating state) controlled by a control board 70 controlling its energized and de-energized states. The first pump 27, the second pump 37, and the motor 50 correspond to a hydraulic pressure control mechanism that controls the hydraulic pressure of the brake fluid of the present invention.

[0029] The control board 70 of the brake hydraulic pressure control device 10 includes a controller 71, which executes a predetermined program or the like to control the above-mentioned hydraulic control mechanisms 40a to 40d, 27, 37, 50, etc. The controller 71 may be one, or may be divided into multiple controllers. A part or all of the controller 71 may be, for example, a microcomputer, a microprocessor unit, etc., or may be configured to be updatable by software such as firmware, or may be a program module executed by a command from a CPU, etc. The controller 71 may be provided on one control board 70, or may be provided on multiple control boards.

[0030] The controller 71 also includes an acquisition unit 71a that acquires detection results from various sensors (e.g., a hydraulic pressure sensor that detects the hydraulic pressure of the brake fluid, a wheel speed sensor that detects the rotational speed of the wheels, an acceleration sensor that detects the acceleration in the roll, pitch, and yaw directions of the motorcycle 1, etc.), and an execution unit 71b that executes control of the operation of the brake system 100 (e.g., normal operation and pressure reduction operation, which will be described later) based on the various information acquired by the acquisition unit 71a (see FIG. 4).

[0031] For example, during normal operation, the control board 70 controls the first solenoid valve 40a and the third solenoid valve 40c to an open state, and controls the second solenoid valve 40b and the fourth solenoid valve 40d to a closed state. In this state, when the rider operates the first operating element 6, the piston (not shown) of the first master cylinder 21 is pushed in according to the amount of operation of the first operating element 6, and the hydraulic pressure of the brake fluid in the first master cylinder 21 increases. The increased hydraulic pressure is supplied to the first wheel cylinder 24 via the first main hydraulic passage 23b, and the hydraulic pressure of the brake fluid in the first wheel cylinder 24 increases. Then, the front wheel friction member 25 is pressed against the front wheel disc rotor 4a according to the hydraulic pressure in the first wheel cylinder 24, generating a frictional force, and the front wheel 4 is braked. Furthermore, when the rider operates the second operating element 7, a piston (not shown) of the second master cylinder 31 is pushed in according to the amount of operation of the second operating element 7, the hydraulic pressure of the brake fluid in the second master cylinder 31 increases, and the increased hydraulic pressure is supplied to the second wheel cylinder 34 via the second main hydraulic passage 33b, thereby increasing the hydraulic pressure of the brake fluid in the second wheel cylinder 34. Then, the rear wheel friction member 35 is pressed against the rear wheel disc rotor 5a according to the hydraulic pressure in the second wheel cylinder 34, generating a frictional force, and the rear wheel 5 is braked.

[0032] Furthermore, the control board 70 executes a pressure reducing operation to reduce the hydraulic pressure of the brake fluid in the first wheel cylinder 24 when it is determined that the rotation of the front wheel 4 is locked or may be locked based on the detection results of various sensors, for example, as a control of the antilock brake operation of the front wheels. During the pressure reducing operation of the first wheel cylinder 24, the controller 71 controls the first solenoid valve 40a to a closed state and the second solenoid valve 40b to an open state, while controlling the motor 50 to be driven. As a result, the brake fluid is released from the first wheel cylinder 24 to the first accumulator 26, the hydraulic pressure of the brake fluid in the first wheel cylinder 24 is reduced, and the braking force of the front wheel 4 is reduced, thereby unlocking the rotation of the front wheel 4 or preventing it from being locked. The brake fluid released to the first accumulator 26 is pumped up by the first pump 27 driven by the motor 50, and returned to a region of the first main fluid passage 23b on the first master cylinder 21 side relative to the first solenoid valve 40a.

[0033] Furthermore, the control board 70 executes a pressure reducing operation to reduce the hydraulic pressure of the brake fluid in the second wheel cylinder 34 when it is determined that the rotation of the rear wheel 5 is locked or may be locked based on the detection results of various sensors, for example, as control of the antilock brake operation of the rear wheel. During the pressure reducing operation of the second wheel cylinder 34, the controller 71 controls the third solenoid valve 40c to a closed state and the fourth solenoid valve 40d to an open state, while controlling the motor 50 to be driven. As a result, the brake fluid is released from the second wheel cylinder 34 to the second accumulator 36, the hydraulic pressure of the brake fluid in the second wheel cylinder 34 is reduced, and the braking force of the rear wheel 5 is reduced, thereby unlocking the rotation of the rear wheel 5 or preventing it from being locked. The brake fluid released to the second accumulator 36 is pumped up by the second pump 37 driven by the motor 50, and returned to a region of the second main fluid passage 33b on the second master cylinder 31 side relative to the fourth solenoid valve 40d.

[0034] In addition, the brake fluid pressure control device 10 may be configured to include a fluid pressure sensor that detects the fluid pressure of the brake fluid input from the first master cylinder 21 and the second master cylinder 31, and / or a fluid pressure sensor that detects the fluid pressure of the brake fluid output to the first wheel cylinder 24 and the second wheel cylinder 34.Such a fluid pressure sensor may be, for example, configured to be arranged in the main flow path or secondary flow path of the brake fluid pressure control device, or may be configured to be arranged in a brake fluid piping connected to the main flow path, or may be configured to be arranged in the master cylinder or wheel cylinder.

[0035] Furthermore, the brake fluid pressure control device 10 may be configured to include, for example, a fluid path that allows the first pump 27 to pump up the brake fluid from the first reservoir 22 and output the brake fluid to the first wheel cylinder 24, and in such a configuration, the control board 70 may be configured to execute a front wheel pressure boosting operation that boosts the hydraulic pressure of the brake fluid in the first wheel cylinder 24 with the brake fluid output by the first pump 27 when it is determined that the braking force of the front wheels 4 is insufficient or may be insufficient based on the detection results of various sensors, for example. In such a configuration, the braking force of the front wheels 4 can be increased by the pressure boosting operation to compensate for the lack of braking force.

[0036] Furthermore, the brake fluid pressure control device 10 may be configured to include, for example, a fluid path that allows the second pump 37 to pump up the brake fluid from the second reservoir 32 and output the brake fluid to the second wheel cylinder 34, and in such a configuration, the control board 70 may be configured to execute a rear wheel pressure increasing operation that increases the hydraulic pressure of the brake fluid in the second wheel cylinder 34 with the brake fluid output by the second pump 37 when it is determined that the braking force of the rear wheel 5 is insufficient or may be insufficient based on the detection results of various sensors, for example. In such a configuration, the braking force of the rear wheel 5 is increased by the rear wheel pressure increasing operation, thereby making up for the lack of braking force.

[0037] As shown in Figures 3 and 4, the brake fluid pressure control device 10 is configured by unitizing a base 60 in which a portion of the above-mentioned brake fluid path is formed as an internal fluid path, first to fourth solenoid valves 40a to 40d, a first pump 27, a second pump 37, a first accumulator 26, a second accumulator 36, a motor 50, a control board 70, and a housing 80 that accommodates the control board 70, etc.

[0038] The base 60 is formed of, for example, an aluminum rectangular parallelepiped block material. Inside the base 60, the above-mentioned first main liquid path 23b, first sub-liquid path 23c, second main liquid path 33a, and second sub-liquid path 33c are formed.

[0039] A motor hole 61H for accommodating the motor 50 is formed in the approximate center of the first surface 60A constituting the exterior of the base 60, and four valve holes 62H for accommodating the first to fourth solenoid valves 40a to 40d are formed around the motor hole 61H in the first surface 60A of the base 60. A bolt hole 63H for engaging with a bolt 18 for fixing the housing 80 to the base 60 is formed in the first surface 60A of the base 60. A pump hole 64H for accommodating a plunger (not shown) of the first pump 27 and the second pump 37 is formed in a second surface 60B constituting the exterior of the base 60 and a third surface 60C opposed to the second surface 60B. An accumulator hole 65H for accommodating the first accumulator 26 and the second accumulator 36 is formed in a fourth surface 60D which continues from the first to third surfaces 60A to 60C of the base body 60 and constitutes the outer appearance of the base body 60. Each surface which constitutes the outer appearance of the base body 60 may include a stepped portion or a curved portion.

[0040] In addition, on the fifth surface 60E which faces the fourth surface 60D of the base 60 and forms the outer appearance, there are formed a first master cylinder port P1 which forms part of the first fluid path 23 and is connected to a brake fluid pipe 23a which connects the first master cylinder 21 and the first main fluid path 23b, a second master cylinder port P2 which forms part of the second fluid path 33 and is connected to a brake fluid pipe 33d which connects the second master cylinder 31 and the second main fluid path 33b, a first wheel cylinder port P3 which forms part of the first fluid path 23 and is connected to a brake fluid pipe 23e which connects the first wheel cylinder 24 and the first main fluid path 23b, and a second wheel cylinder port P4 which forms part of the second fluid path 33 and is connected to a brake fluid pipe 33e which connects the second wheel cylinder 34 and the second main fluid path 33b.

[0041] The motor 50 is inserted into the motor hole 61H and attached to the base 60. An eccentric body 52 that rotates together with the output shaft 51 is attached to the output shaft 51 of the motor 50. Inside the pump hole 64H, the plungers of the first pump 27 and the second pump 37 are arranged so as to be pressed against the outer circumferential surface of the eccentric body 52. ​​When the eccentric body 52 rotates, the plungers of the first pump 27 and the second pump 37 reciprocate in the axial direction of the pump hole 64H, so that the brake fluid is conveyed from the suction side of the first pump 27 and the second pump 37 to the discharge side of each of the pumps. In addition, the motor 50 includes an electric terminal 53 that is electrically connected to the control board 70 at the end opposite to the side where the output shaft 51 is provided. In this embodiment, the motor 50 is configured to be attached to the base 60, but the motor may be configured to be attached to, for example, a housing.

[0042] The first to fourth solenoid valves 40a to 40d are each composed of a valve body and a coil. The first to fourth valve bodies 41a to 41d of the first to fourth solenoid valves 40a to 40d are inserted into the valve holes 62H, and the first to fourth coils 42a to 42d of the first to fourth solenoid valves 40a to 40d are erected on the first surface 60A of the base 60, thereby assembling the first to fourth solenoid valves 40a to 40d to the base 60.

[0043] The first accumulator 26 and the second accumulator 36 are assembled by being housed in the accumulator holes 65H, respectively.

[0044] As described below, the control board 70 includes a board 72 on which a controller 71, electrical wiring constituting an electronic circuit, and various electronic components (such as an integrated circuit chip 73) are arranged. The electronic circuit of the control board 70 is electrically connected to an electrical terminal 53 of the motor 50, electrical terminals 43a-43d of the first to fourth coils 42a-42d, output terminals (not shown) of various sensors, and a connector 75 connected to an external device (not shown) provided outside the brake fluid pressure control device 10.

[0045] The housing 80 is made of, for example, resin and is formed in a substantially rectangular parallelepiped shape. The housing 80 includes a first housing 81 that houses the first to fourth solenoid valves 40a to 40d and the motor 50, and a second housing 87 that houses the control board 70. Each surface constituting the exterior of the housing 80 may be formed in a shape that includes a step portion, a curved portion, or the like.

[0046] The first housing 81 is a member attached to the base 60, and for example, a silicon-based sealing material (not shown) is disposed between the first housing 81 and the base 60. The first housing 81 includes an enclosing portion 81a that encloses the first to fourth solenoid valves 40a to 40d and the motor 50 when attached to the base 60, and a connector portion 81b that is formed on the side of the enclosing portion 81a and that houses the above-mentioned connector 75.

[0047] The surrounding portion 81a includes a first surface 82A facing the base 60 and a second surface 82B facing the control board 70 when the first housing 81 is attached to the base 60. A first opening 84 is formed on the second surface 82B side of the surrounding portion 81a in an area facing the control board 70. The control board 70 is accommodated in the surrounding portion 81a through the first opening 84. In addition, a second opening 85 facing the first surface 60A of the base 60 is formed on the first surface 82A side of the surrounding portion 81a. The first to fourth coils 42a to 42d and the motor 50 are accommodated in the surrounding portion 81a through the second opening 85.

[0048] The surrounding portion 81a has a through hole 83H through which the bolt 18 is inserted from the first surface 82A side and penetrates to the second surface 82B side. The bolt 18 is inserted into the through hole 83H and engages with the bolt hole 63H of the base body 60, so that the first housing 81 is sandwiched and fixed between the head of the bolt 18 and the base body 60. The surrounding portion 81a also has insertion holes (not shown) through which the electric terminal 53 of the motor 50 and the electric terminals 43a to 43d of the first to fourth coils 42a to 42d are inserted from the first surface 82A side and penetrate to the second surface 82B side. The bolt 18 for fixing the first housing 81 to the base body 60 may be one or more, and the bolt hole 63H of the base body 60 and the through hole 83H of the first housing 81 may be formed corresponding to the number of the bolts. The base 60 and the housing 80 may also be secured together by an adhesive.

[0049] The second housing 87 is formed as a separate member from the first housing 81, and when attached to the first housing 81, covers the control board 70 and closes the first opening 84 of the first housing 81. A silicon-based sealing material containing silicon as a main component is disposed between the first housing 81 and the second housing 87.

[0050] For example, with a silicon-based sealant 95 applied to an area of ​​the second housing 87 facing the edge of the first opening 84 of the first housing 81, the second housing 87 is moved in the attachment direction D and attached to the first housing 81. This bonds the first housing 81 and the second housing 87 together, and seals the gap between the first housing 81 and the second housing 87, preventing moisture and the like from entering the housing 80 from between the first housing 81 and the second housing 87. That is, the silicon-based sealant 95 also functions as an adhesive.

[0051] The first housing 81 has a protrusion 86 protruding from its outer surface, and the second housing 87 has an engagement portion 88 that engages with the protrusion 86 of the first housing 81 when the second housing 87 is attached to the first housing 81. When the second housing 87 is moved in an attachment direction D (see FIG. 4 ) for attachment and attached to the first housing 81, the protrusion 86 is inserted into an opening formed in the engagement portion 88 and the engagement portion 88 engages with the protrusion 86, thereby fixing the second housing 87 to the first housing 81.

[0052] <About the control board> A control board 70 provided in a brake fluid pressure control device 10 as a control device according to this embodiment will be described with reference to FIGS. 4 and 5. FIG.

[0053] 4 and 5, the control board 70 includes a board 72 and electronic components (e.g., an integrated circuit chip 73, a switching element 74, etc.) mounted on the board 72. The board 72 is a so-called printed circuit board (PCB) and is configured by providing conductor wiring on or inside an insulating board, and the control board 70 is configured by mounting electronic components (e.g., the integrated circuit chip 73, etc.) on the board 72 by soldering, and is configured in a state in which it operates as an electronic circuit.

[0054] The electronic components mounted on the substrate 72 include, for example, at least one of an integrated circuit chip 73, a switching element 74, a resistor (not shown), a capacitor element (not shown), a coil element (not shown), a battery (not shown), etc.

[0055] The integrated circuit chip 73 is configured by housing a semiconductor chip on which an integrated circuit (IC) is formed in a package. The package of the integrated circuit chip 73 configures the external surface of the integrated circuit chip 73 and includes a surface 73a facing the opposite side to the substrate 72 when the integrated circuit chip 73 is mounted on the substrate 72. The surface 73a of the integrated circuit chip 73 is configured to be visible from the outside of the substrate 72 when the integrated circuit chip 73 is mounted on the substrate 72. The integrated circuit formed in the integrated circuit chip 73 may realize one of the functions of an analog IC, a driver IC, a power supply IC, a communication modem IC, a standard logic IC, a microprocessor (MPU: Micro-Processing Unit), a DRAM (Dynamic Random Access Memory), etc., or may realize a plurality of these functions.

[0056] 5, the surface 73a of the integrated circuit chip 73 includes a flat surface portion, and the surface portion is provided with a printed portion 73b on which product information PI related to the integrated circuit chip 73 is displayed. The product information PI includes at least one of the following information: model number, manufacturer name, product name, place of manufacture, and technical information of the integrated circuit chip 73. The product information PI is provided by the manufacturer of the integrated circuit chip 73, and is displayed by printing or the like during the manufacturing process of the integrated circuit chip 73 before the control board 70 is manufactured. The integrated circuit chip 73 of this embodiment has a wider flat surface portion than the switching element 74, for example, and is the electronic component with the widest area of ​​the flat surface portion (surface 73a) among the electronic components mounted on the board 72 of this embodiment.

[0057] Moreover, a display section 73c is provided on the surface 73a of the integrated circuit chip 73, on which traceability information TI relating to the manufacture of the control board 70 is displayed. The traceability information TI includes at least one of information on the manufacturing date, manufacturing factory, manufacturing line, and serial number on which the control board 70 was manufactured by mounting electronic components and the like on the board 72. By displaying the traceability information TI of the control board 70 on the display section 73c, the manufacturing process of the control board 70 can be traced. Furthermore, since the information included in the traceability information TI is information on the control board 70, in a conventional control board, the information is displayed on the surface of the board by, for example, printing, engraving, edging, etc., but this information is not displayed on the surface of the board 72 of this embodiment. As a result, in the control board 70 of this embodiment, the traceability information TI is displayed on the display section 73c of the integrated circuit chip 73, but is not displayed on the surface of the board 72, so that the area of ​​the portion on the surface of the board 72 on which the information is displayed can be reduced, and the control board 70 can be made smaller.

[0058] Moreover, the control board 70 is arranged in the housing 80 at a position facing the second housing 87 with the surface 73a of the integrated circuit chip 73 facing the second housing 87 (see FIG. 4), and the display section 73c of the integrated circuit chip 73 is visible from the outside of the brake fluid pressure control device 10 when the second housing 87 is removed from the first housing 81. This allows, for example, during the manufacture of the brake fluid pressure control device 10, the traceability information TI to be printed and displayed on the display section 73c within the period from after the hydraulic control mechanism and the first housing 81 are attached to the base 60 until before the second housing 87 is attached to the first housing 81, so that the degree of freedom in the timing of adding the traceability information TI to the display section 73c can be increased. Also, for example, when the brake fluid pressure control device 10 breaks down, the traceability information TI can be made available for confirmation simply by removing the second housing 87 from the first housing 81, so that the confirmation work of the traceability information TI can be simplified.

[0059] Furthermore, the display unit 73c of the integrated circuit chip 73 displays at least traceability information TI related to the manufacture of the control board 70, and may further display other information. In addition to the above-mentioned traceability information TI, the display unit 73c of this embodiment displays component information CI related to the components included in the brake fluid pressure control device 10. The component information CI includes information related to at least one of the base 60 and the hydraulic control mechanism (the solenoid valves 40a to 40d, the pumps 27, 37, and the motor 50) of the brake fluid pressure control device 10 (for example, at least one of the model number, manufacturer name, product name, place of manufacture, and technical information of each component). Since the information included in the component information CI is information related to the components, in conventional brake fluid pressure control devices, it is displayed by printing, engraving, attaching a label, or the like to the main body of each component. As a result, in the control board 70 of this embodiment, the component information CI is displayed on the display section 73c of the integrated circuit chip 73, so that in the event of a breakdown in the brake fluid pressure control device 10, for example, the component information CI can be made available for confirmation simply by removing the second housing 87 from the first housing 81, simplifying the task of confirming the component information CI. Also, the information on each component can be confirmed without inquiring to a manufacturing factory or the like for each component.

[0060] For example, information on the first pump 27 and the second pump 37, which are hydraulic control mechanisms, is included as one piece of component information CI. Information on the first pump 27 and the second pump 37 includes, for example, information on performance at the time of shipment based on the results of tests performed on each pump before shipment from the factory (for example, the value of the discharge amount confirmed by the test). As a result, information on each of the pumps 27, 37 is included in the component information CI that can be easily confirmed by removing the second housing 87 from the first housing 81, and therefore, in cases where it becomes necessary to analyze the pump after shipment of the brake hydraulic control device 10, the task of confirming the information at the time of shipment can be simplified.

[0061] Furthermore, the traceability information TI and the component information CI are converted into a code (e.g., an identifier such as a two-dimensional code or a barcode) and displayed by being printed directly with ink on the display section 73c on the surface 73a of the integrated circuit chip 73. In the display section 73c of the present embodiment, a code in which the traceability information TI and the component information CI are converted into one identifier is displayed (see FIG. 5). The code displayed on the display section 73c may, for example, include the traceability information TI and the component information CI in one code, or may, for example, include the traceability information TI and the component information CI in a plurality of codes. When the traceability information TI and the component information CI are included in a plurality of codes, for example, the traceability information TI and the component information CI may be included in separate codes, or the traceability information TI and the component information CI may be included across a plurality of codes.

[0062] In this embodiment, the display unit 73c for traceability information TI is provided on the surface 73a of the integrated circuit chip 73 which is an electronic component mounted on the substrate 72 of the control board 70. However, the electronic component on which the display unit for traceability information is provided is not limited to an integrated circuit chip, and the display unit for traceability information may be provided on the surface of an electronic component other than an integrated circuit chip, such as a switching element, a capacitor element, a coil element, a battery, etc.

[0063] In addition, in this embodiment, a display unit 73c for traceability information TI is provided on the surface 73a of one integrated circuit chip 73 mounted on the substrate 72 of the control board 70, but the display units for displaying the traceability information may be provided on multiple electronic components. For example, different traceability information may be displayed on each of the display units provided on the multiple electronic components, or one or multiple pieces of traceability information may be displayed across display units provided on the multiple electronic components.

[0064] In the present embodiment, the traceability information TI is directly printed with ink on the display section 73c of the integrated circuit chip 73 mounted on the substrate 72 of the control substrate 70, so that the traceability information TI is displayed on the display section 73c, but the traceability information may be displayed by a method other than directly printing the traceability information on the display section, and for example, the traceability information may be printed, engraved, or embossed on a label, and the label may be attached to the display section of an electronic component such as an integrated circuit chip, so that the traceability information is displayed on the display section. Furthermore, the label on which the traceability information is printed or the like may be attached so as to extend beyond the display section on the electronic component, or the label may be formed to have an area larger than the area of ​​the display section.

[0065] Furthermore, in this embodiment, the configuration applies a brake fluid pressure control device 10 that controls the hydraulic pressure of the brake fluid in the brake system 100 of the motorcycle 1 as the control device, but the control device is not limited to the brake fluid pressure control device 10 of the motorcycle 1, and may be any control device having a control board on which electronic components are mounted, and may be, for example, a control device for electrical equipment, a control device for communication equipment, or various control devices for vehicles (e.g., automobiles, trucks, saddle-type vehicles, etc.) (e.g., control devices that control the engine or motor that drives the vehicle, control devices that control the suspension of the vehicle, control devices that control the navigation of the vehicle, etc.).

[0066] <About the effects> Conventional control devices include, for example, an electronic circuit board on which electronic components and the like are mounted, and an identifier including information about the electronic circuit board (e.g., information about the model number of the electronic circuit board, information about the solder material used, and the like) is displayed on the surface of the electronic circuit board. In recent control devices, it is sometimes desired to add information about the traceability of the electronic circuit board and the like (e.g., manufacturing time, manufacturing factory, and the like) to enable tracing of the manufacturing process of the electronic circuit board and the like. However, identifiers (e.g., bar codes, two-dimensional codes, and the like) tend to have a larger display area as the amount of information they contain increases, so that if an identifier including information about traceability is provided on an electronic circuit board, the electronic circuit board may become larger.

[0067] In contrast, the brake fluid pressure control device 10 as a control device in this embodiment is equipped with a control board 70, which includes a board 72 and an integrated circuit chip 73 mounted on the board 72, and the surface 73a of the integrated circuit chip 73 is provided with a display unit 73c on which at least traceability information TI regarding the manufacture of the control board 70 is displayed.

[0068] According to this configuration, a display unit 73c that displays traceability information TI regarding the manufacture of the control board 70 is provided on the surface 73a of the integrated circuit chip 73 mounted on the board 72, so that the control board 70 can be made smaller while still displaying the traceability information TI.

[0069] The brake fluid pressure control device 10 as a control device in this embodiment includes a control board 70 on which electronic components are mounted on a substrate 72, and a display unit 73c on which traceability information TI is displayed is provided on a surface 73a of an integrated circuit chip 73, which is the electronic component with the largest planar area among the electronic components mounted on the substrate 72.

[0070] According to this configuration, the display unit 73c on which the traceability information TI is displayed is provided on the surface 73a of the integrated circuit chip 73, which has the largest planar area among the electronic components mounted on the substrate 72, so that the control substrate 70 can be made smaller while ensuring that the display unit 73c has a relatively large display area.

[0071] The brake fluid pressure control device 10 as a control device in this embodiment is equipped with a control board 70 on which electronic components are mounted on a substrate 72, and a display unit 73c on which traceability information TI is displayed is provided on a surface 73a of an integrated circuit chip 73, which is an electronic component mounted on the substrate 72, and the display unit 73c is configured to display the traceability information TI coded, for example, as a barcode, a two-dimensional code, or the like.

[0072] According to this configuration, the display unit 73c provided on the surface 73a of the integrated circuit chip 73 displays the coded traceability information TI, so that the traceability information TI can be displayed at a relatively high density, and the control board 70 can be made smaller.

[0073] The brake fluid pressure control device 10 as a control device in this embodiment is provided with a control board 70 on which electronic components are mounted on a substrate 72, and a display unit 73c on which traceability information TI is displayed is provided on a surface 73a of an integrated circuit chip 73 mounted on the substrate 72, and the display unit 73c is configured to display the printed traceability information TI.

[0074] According to this configuration, the display unit 73c provided on the surface 73a of the integrated circuit chip 73 displays the printed traceability information TI, so that the degree of freedom in timing for generating the traceability information TI and displaying it on the display unit 73c during the manufacturing process of the brake fluid pressure control device 10 can be improved. For example, the traceability information TI can be printed and displayed on the display unit 73c at at least one of the stages of manufacturing the control board 70, attaching the control board 70 to the first housing 81, and attaching the second housing 87 to the first housing 81 to which the control board 70 is attached, so that the traceability of the manufacturing process of the brake fluid pressure control device 10 can be improved. In addition, for example, the traceability information TI can be printed and displayed on the display unit 73c in an additional manner at each of these stages, so that the traceability of the manufacturing process of the brake fluid pressure control device 10 can be improved.

[0075] The brake fluid pressure control device 10 as a control device in this embodiment is equipped with a control board 70 on which electronic components are mounted on a substrate 72, and a display unit 73c is provided on a surface 73a of an integrated circuit chip 73 mounted on the substrate 72, where traceability information TI regarding the manufacture of the control board 70 is displayed. The traceability information TI includes information regarding at least one of the following: the manufacture date of the control board 70, the manufacturing plant that manufactures the control board 70, the manufacturing line that manufactures the control board 70, and the serial number assigned to each of the control boards 70.

[0076] According to this configuration, the traceability information TI displayed on the display unit 73c provided on the surface 73a of the integrated circuit chip 73 includes information regarding at least one of the manufacturing date, manufacturing factory, manufacturing line, and serial number of the control board 70. Therefore, at least one of these pieces of information can be displayed on the display unit 73c, thereby making it possible to reduce the size of the control board 70 and improving the traceability of the manufacturing process of the control board 70.

[0077] The brake fluid pressure control device 10 as the control device of this embodiment is a control device that controls the anti-lock brake operation of the brake system 100 of the motorcycle 1, and includes a base 60 in which the brake fluid flow paths 23b, 23c, 33b, 33c of the brake system 100 are formed, a hydraulic pressure control mechanism (first solenoid valves 40a-40d, pumps 27, 37, motor 50) that controls the hydraulic pressure of the brake fluid, a first housing 81 that accommodates the hydraulic pressure control mechanism and is attached to the base 60, and a second housing 87 that accommodates a control board 70 and is attached to the opposite side of the first housing 81 from the base 60, and the control board 70 is disposed at a position facing the second housing 87, with the surface 73a of the integrated circuit chip 73 facing the second housing 87, and a display unit 73c provided on the surface 73a of the integrated circuit chip 73 that displays the traceability information TI is configured to be visible from outside the brake fluid pressure control device 10 (control device) when the second housing 87 is removed from the first housing 81.

[0078] According to this configuration, the control board 70 of the brake fluid pressure control device 10 is arranged with the surface 73a of the integrated circuit chip 73 facing the second housing 87, and the display unit 73c provided on the surface 73a of the integrated circuit chip 73 and displaying the traceability information TI is visible from the outside of the brake fluid pressure control device 10 when the second housing 87 is removed from the first housing 81. This allows the control board 70 to be made smaller, and the traceability information TI can be confirmed simply by removing the second housing 87 from the first housing 81. In addition, the display unit 73c of the integrated circuit chip 73 is visible from the outside of the brake fluid pressure control device 10 when the second housing 87 is removed from the first housing 81. Therefore, during the manufacture of the brake fluid pressure control device 10, the traceability information TI can be added and displayed on the display unit 73c during the period from after the hydraulic control mechanism and the first housing 81 are attached to the base 60 until before the second housing 87 is attached to the first housing 81. This improves the traceability of the manufacturing process of the control board 70.

[0079] The brake fluid pressure control device 10 as a control device in this embodiment is a brake fluid pressure control device 10 that controls the anti-lock brake operation of the brake system 100 of the motorcycle 1, and is provided with a control board 70 on which an integrated circuit chip 73 is mounted on a substrate 72, and a display unit 73c is provided on a surface 73a of the integrated circuit chip 73, which displays at least traceability information TI relating to the manufacture of the control board 70, and the display unit 73c is further configured to display information relating to at least one of the base 60 and the hydraulic control mechanisms 40a-40d, 50.

[0080] According to this configuration, the control board 70 of the brake fluid pressure control device 10 is provided with a display unit 73c on the surface 73a of the integrated circuit chip 73, which displays at least traceability information TI related to the manufacture of the control board 70, and the display unit 73c further displays information related to at least one of the base 60 and the fluid pressure control mechanisms 40a to 40d, 50. Therefore, by having the display unit 73c display multiple pieces of information, the control board 70 can be made smaller and the traceability of the manufacturing process of the brake fluid pressure control device 10 can be improved.

[0081] The brake fluid pressure control device 10 as a control device in this embodiment is equipped with a control board 70, and a display unit 73c is provided on a surface 73a of an integrated circuit chip 73 of the control board 70, on which at least traceability information TI regarding the manufacture of the control board 70 is displayed, and the control board 70 is configured to be mounted on a motorcycle 1.

[0082] Saddle-type vehicles such as the motorcycle 1 have relatively small vehicle bodies among various vehicles and have relatively little space for mounting various devices, so there is a demand for miniaturization of the control device, etc. In response to this, according to the above-mentioned configuration, the brake fluid pressure control device 10 as the control device is provided with a display unit 73c that displays the traceability information TI on the surface 73a of the integrated circuit chip 73 of the control board 70, so that the control board 70 can be miniaturized, and the demand for miniaturization of the control device in the saddle-type vehicle can be met.

[0083] In this embodiment, the display unit 73c of the traceability information TI is provided on the surface 73a of the integrated circuit chip 73 as an electronic component mounted on the substrate 72 of the control substrate 70, but the electronic component on which the display unit of the traceability information is provided is not limited to the integrated circuit chip, and the display unit of the traceability information may be provided on the surface of an electronic component other than the integrated circuit chip, for example, a switching element, a capacitor element, a coil element, a battery, etc. With this configuration, the control substrate of the control device can be made smaller.

[0084] In this embodiment, the display unit 73c for the traceability information TI is provided on the surface 73a of one integrated circuit chip 73 mounted on the substrate 72 of the control substrate 70, but the display units for displaying the traceability information may be provided on multiple electronic components, for example, different traceability information may be displayed on each of the display units provided on the multiple electronic components, or one piece of traceability information may be displayed across the display units provided on the multiple electronic components. Even with such a configuration, the control substrate of the control device can be made smaller.

[0085] In the present embodiment, the traceability information TI is directly printed with ink on the display section 73c of the integrated circuit chip 73 mounted on the substrate 72 of the control substrate 70, so that the traceability information TI is displayed on the display section 73c. ​​However, the traceability information may be displayed on the display section by a method other than directly printing the traceability information. For example, the traceability information may be printed, engraved, or embossed on a label, and the label may be attached to the display section of an electronic component such as an integrated circuit chip, so that the traceability information is displayed on the display section. Even with such a configuration, the control substrate of the control device can be made smaller. Note that the label on which the traceability information is printed or the like may be attached so as to extend beyond the display section on the electronic component, or may be formed to have an area larger than the area of ​​the display section. With such a configuration, more information can be displayed.

[0086] In addition, in this embodiment, the configuration applies a brake fluid pressure control device 10 that controls the hydraulic pressure of the brake fluid in the brake system 100 of the motorcycle 1 as the control device, but the control device is not limited to the brake fluid pressure control device 10 of the motorcycle 1, and may be any control device equipped with a control board on which electronic components are mounted, such as a control device for an electrical device, a control device for a communication device, or various control devices for a vehicle (e.g., an automobile, truck, straddle-type vehicle, etc.) (e.g., a control device that controls an engine or motor that drives a vehicle, a control device that controls a suspension of a vehicle, a control device that controls navigation of a vehicle, etc.). Even with such a configuration, the control board of the control device can be made smaller while still displaying traceability information.

[0087] Although the brake fluid pressure control device 60 according to the present embodiment has been described above, the brake fluid pressure control device according to the present invention is not limited to the description of the present embodiment. For example, only a part of the present embodiment may be implemented. [Explanation of symbols]
