[0011] Summary of the Invention

[0012] [Problem to be solved by the invention]

[0013]

[0004] In devices such as those described in Patent Document 1, at least two communication lines are required between the devices to perform balanced communication. Therefore, in a saddle-type vehicle equipped with such devices, there is a risk that the installation space for the devices will increase, for example, due to an increase in the amount of wiring installed on the vehicle body or an increase in the number of connector pins in the devices, which will increase the size of the devices.

[0014]

[0005] The present invention has been made in light of the above-mentioned problems, and has a first object to provide a straddle-type vehicle device that can reduce installation space. A second object of the present invention is to provide a straddle-type vehicle equipped with such a straddle-type vehicle device.

[0015] [Means for solving the problem]

[0016]

[0006] The straddle-type vehicle equipment according to the present invention comprises a housing, a control device provided within the housing and having a pair of connection parts for inputting and / or outputting balanced communication signals, a connector provided in the housing and having pins electrically connected to external equipment via communication lines, and a conversion device provided within the housing for converting between balanced communication signals and unbalanced communication signals, the conversion device having a pair of first relay connection parts electrically connected to the pair of connection parts and a second relay connection part electrically connected to the pins.

[0017]

[0007] Furthermore, the saddle-type vehicle according to the present invention is equipped with the saddle-type vehicle equipment according to the present invention.

[0018] [Effects of the Invention]

[0019]

[0008] The saddle-type vehicle equipment according to the present invention is a device that is provided in a housing together with a control device that inputs and / or outputs balanced communication signals, and converts between balanced communication signals and unbalanced communication signals. The device includes a pair of first relay connection parts electrically connected to a pair of connection parts, and a conversion device having a second relay connection part electrically connected to a pin, and therefore can communicate with external equipment outside the housing via unbalanced communication. In other words, the saddle-type vehicle equipment can communicate with the external equipment using a single communication line. Therefore, in the saddle-type vehicle equipment, the number of communication lines and the number of connector pins can be reduced, and the installation space for the saddle-type vehicle equipment and the communication lines in the saddle-type vehicle can be reduced.

[0026] DETAILED DESCRIPTION OF THE INVENTION

[0027]

[0010] Hereinafter, an example of a saddle-ride type vehicle device and a saddle-ride type vehicle according to the present invention will be described with reference to the drawings.

[0028]

[0011] In this embodiment, an example will be described in which the saddle-riding vehicle device according to the present invention is mounted on a motorcycle as a saddle-riding vehicle. However, the saddle-riding vehicle device according to the present invention may be employed in saddle-riding vehicles other than motorcycles. A saddle-riding vehicle is a vehicle on which a rider straddles. Examples of saddle-riding vehicles other than motorcycles include motorcycles, buggies, and bicycles. A motorcycle refers to a motorcycle, a tricycle, or the like that uses at least one of an engine and an electric motor as a drive source. Examples of motorcycles include motorcycles, scooters, and electric scooters. A bicycle refers to any vehicle that can be propelled on a road by applying pedal force to the pedals. Examples of bicycles include a standard bicycle, an electrically assisted bicycle, and an electric bicycle.

Furthermore, illustrations of detailed structures are simplified or omitted as appropriate. Furthermore, duplicated explanations are simplified or omitted as appropriate.

[0031] <Configuration of saddle riding type vehicle and equipment for saddle riding type vehicle> The configuration of the equipment for a saddle riding type vehicle according to this embodiment and the saddle riding type vehicle equipped with the equipment for a saddle riding type vehicle will be described.

[0032]

[0014] Fig. 1 is a diagram showing the configuration of a saddle-riding type vehicle equipped with saddle-riding type vehicle equipment according to an embodiment of the present invention. The saddle-riding type vehicle 100 includes a body 1, a handlebar 2 rotatably held on the body 1, a front wheel 3 rotatably held together with the handlebar 2 on the body 1, and a rear wheel 4 rotatably held on the body 1. In this embodiment, the saddle-riding type vehicle 100 is equipped with an engine 5 as a drive source. The drive source of the saddle-riding type vehicle 100 may be an electric motor or the like.

[0033]

[0015] A saddle-ride type vehicle 100 is equipped with a brake system 10. The brake system 10 includes a brake lever 11, a first hydraulic circuit 12 filled with brake fluid, a brake pedal 13, and a second hydraulic circuit 14 filled with brake fluid. The brake lever 11 is provided on a handlebar 2 and is operated by the driver's hand. The first hydraulic circuit 12 generates a braking force in a rotor 3 a that rotates together with a front wheel 3 according to the amount of operation of the brake lever 11. The brake pedal 13 is provided on the bottom of the vehicle body 1 and is operated by the driver's foot. The second hydraulic circuit 14 generates a braking force in the rotor 4 a that rotates together with the rear wheel 4 according to the amount of operation of the brake pedal 13.

[0034]

[0016] The brake lever 11 and the brake pedal 13 are examples of a brake operating unit. For example, a brake pedal other than the brake pedal 13 provided on the vehicle body 1 may be used as a brake operating unit instead of the brake lever 11. Also, for example, a brake lever other than the brake lever 11 provided on the handlebars 2 may be used as a brake operating unit instead of the brake pedal 13. Furthermore, the first hydraulic circuit 12 may generate a braking force in a rotor 4 a that rotates together with the rear wheel 4 according to the amount of operation of the brake lever 11 or the amount of operation of a brake pedal other than the brake pedal 13 provided on the vehicle body 1. In addition, the second hydraulic circuit 14 may generate a braking force in the rotor 3 a that rotates together with the front wheel 3 according to the amount of operation of the brake pedal 13 or the amount of operation of a brake lever other than the brake lever 11 provided on the handlebars 2.

[0035]

[0017] The saddle-riding vehicle 100 is equipped with a saddle-riding vehicle device 20. In other words, the saddle-riding vehicle 100 is equipped with the saddle-riding vehicle device 20. In conventional saddle-riding vehicles, the saddle-riding vehicle device 20 communicates with external devices using balanced communication such as CAN communication. The saddle-riding vehicle device 20 is, for example, a hydraulic control unit that controls an on-off valve (not shown) of at least one of the first hydraulic circuit 12 and the second hydraulic circuit 14, and controls the braking force of at least one of the rotors 3a and 4a. The saddle-riding vehicle device 20 is, for example, an engine control unit that controls the output of the engine 5.

[0036]

[0018] Fig. 2 is a diagram illustrating a straddle-type vehicle device 20 according to an embodiment of the present invention. The straddle-type vehicle device 20 includes a housing 21, a control device 30, a connector 40, and a conversion device 50. The housing 21 forms the outer shell of the straddle-type vehicle device 20. The control device 30 controls the controlled object and is housed in the housing 21. For example, the control device 30 is configured by electronic components (such as a computing device) mounted on a board 22. For example, if the straddle-type vehicle device 20 is a hydraulic control unit, the control device 30 controls an on-off valve (not shown) of at least one of the first hydraulic circuit 12 and the second hydraulic circuit 14. Also, for example, if the saddle-riding type vehicle equipment 20 is an engine control unit, the control device 30 is a control device that controls the output of the engine 5. The control device 30 has a pair of connection parts 31 a and 31 b that input and output balanced communication signals. Note that the connection parts 31 a and 31 b may also input or output balanced communication signals. The connector 40 has pins 41. The connector 40 is provided in the housing 21 so that the pins 41 are exposed to the outside of the housing 21.

[0037]

[0019] The conversion device 50 is a device that converts between balanced communication signals and unbalanced communication signals. The conversion device 50 is housed in a housing 21 and is configured, for example, by an electronic circuit or the like provided on a board 22. The conversion device 50 has a pair of first relay connection parts 51a and 51b electrically connected to the pair of connection parts 31a and 31b of the control device 30. The conversion device 50 also has a second relay connection part 52 electrically connected to the pin 41 of the connector 40. That is, when a balanced communication signal is input from the pair of connection parts 31a and 31b of the control device 30 to the pair of first relay connection parts 51a and 51b, the conversion device 50 converts the balanced communication signal into an unbalanced communication signal. The conversion device 50 then outputs the unbalanced communication signal from the second relay connection part 52 to pin 41 of the connector 40. Also, when an unbalanced communication signal is input from pin 41 of the connector 40 to the second relay connection part 52, the conversion device 50 converts the unbalanced communication signal into a balanced communication signal. Then, the conversion device 50 outputs the balanced communication signal from the pair of first relay connection units 51a and 51b to the pair of connection units 31a and 31b of the control device 30.

[0038]

[0020] When the saddle-riding type vehicle device 200 configured in this manner is mounted on the saddle-riding type vehicle 100, the pin 41 of the connector 40 electrically connected to the second relay connection unit 52 of the conversion device 50 is electrically connected to the communication line 110. FIG. 2 shows an example in which the pin 41 of the connector 40 is electrically connected to the communication line 110 via the connection line 111. The communication line 110 is also connected to an external device 200. The external device 200 is a device mounted on the saddle-riding type vehicle 100 that is different from the saddle-riding type vehicle device 200. In other words, the pin 41 of the connector 40 is electrically connected to the external device 200 via the communication line 110. This allows the saddle-type vehicle device 20 to send and receive unbalanced communication signals to and from the external device 2000 via the communication line 110.

[0039]

[0021] The saddle-riding type vehicle device 20 may be configured to only receive unbalanced communication signals from the external device 200, or may be configured to only transmit unbalanced communication signals to the external device 200. The external device 200 may, for example, have an internal converter 50 and be configured to be able to transmit and receive unbalanced communication signals. For example, the external device 200 is electrically connected to the communication line 110 via a converter (not shown) that is provided between the external device 200 and the communication line 110 and converts between balanced communication signals and unbalanced communication signals.

[0040]

[0022] Conventional saddle-type vehicle devices communicate with external devices using balanced communication (e.g., CAN). This balanced communication requires two communication lines, equivalent to communication line 110, for communication between devices. In other words, when conventional saddle-type vehicle devices are installed in a saddle-type vehicle, the installation space for the communication lines becomes large. Furthermore, conventional saddle-type vehicle devices that communicate using balanced communication require pins to connect to two communication lines, so the number of connector pins also increases. As a result, conventional saddle-type vehicle devices have large connectors, and therefore the saddle-type vehicle devices themselves become large. In other words, when conventional saddle-type vehicle devices are installed in a saddle-type vehicle, the installation space for the saddle-type vehicle devices themselves becomes large.

[0041]

[0023] On the other hand, the saddle-riding type vehicle device 20 according to this embodiment can communicate with the external device 200 using unbalanced communication. That is, as shown in FIG. 2, the saddle-riding type vehicle device 20 according to this embodiment can communicate with the external device 200 using a single communication line 110. Therefore, when the saddle-riding type vehicle device 20 according to this embodiment is mounted on a saddle-riding type vehicle 100, the installation space for the communication 110 can be reduced compared to conventional devices. Furthermore, because the saddle-riding type vehicle device 20 according to this embodiment can communicate using a single communication line 110, the number of pins 41 of the connector 40 can be reduced compared to conventional saddle-riding type vehicle devices. Therefore, the saddle-riding type vehicle device 20 according to this embodiment can be made smaller than conventional saddle-riding type vehicle devices, and the space required to install the saddle-riding type vehicle device 20 itself can also be made smaller. Therefore, when the saddle-riding type vehicle device 20 according to this embodiment is mounted on a saddle-riding type vehicle 100, the installation space required can be reduced compared to conventional devices.

[0042]

[0024] Although the control device 30 and the conversion device 50 may be mounted on separate boards, in this embodiment, the control device 30 and the conversion device 50 are mounted on the same board 22. In other words, in this embodiment, the components constituting the control device 30 and the components constituting the conversion device 50 are mounted on the same board 22. When the control device 30 and the conversion device 50 are mounted on the same board 22, the control device 30 and the conversion device 50 can be housed together in the housing 21. On the other hand, when the control device 30 and the conversion device 50 are mounted on separate boards, the control device 30 and the conversion device 50 must be housed separately in the housing 21, which increases the number of assembly steps. Therefore, when the control device 30 and the conversion device 50 are mounted on the same substrate 22, the assembly workability of the saddle-riding type vehicle equipment 20 is improved, and the manufacturing cost of the saddle-riding type vehicle equipment 20 can be reduced.

[0043]

[0025] The saddle-riding type vehicle equipment 20 according to this embodiment includes a grounding unit 42 connected to the conversion device 50. The grounding unit 42 is electrically connected to the body 1 of the saddle-riding type vehicle 100 by a grounding wire 112. In other words, the grounding unit 42 is electrically connected to the body 1 of the saddle-riding type vehicle 100. When the saddle-riding type vehicle equipment 20 including this grounding unit 42 is mounted on the saddle-riding type vehicle 100, the grounding wire 112 need only be electrically connected to a part of the body 1 that is close to the saddle-riding type vehicle equipment 20. This reduces the installation space for the grounding wire 112, and further reduces the installation space for the saddle-riding type vehicle equipment 20 in the saddle-riding type vehicle 100. In addition, the earthing portion 42 may be provided in the connector 40, or may be provided at a location other than the connector 40.

[0044] [ 0 0 2 6 ]

[0045] <Effects of the saddle-riding type vehicle device> The saddle-riding type vehicle device 20 according to this embodiment includes a housing 21, a control device 30, a connector 40, and a conversion device 50. The control device 30 is provided within the housing 21 and has a pair of connection portions 31a and 31b that input and / or output balanced communication signals. The connector 40 is provided in the housing 21 and has pins 41 that are electrically connected to the external device 200 via a communication line 110. The conversion device 50 is provided within the housing 21 and is a device that converts between balanced communication signals and unbalanced communication signals. The conversion device 50 has a pair of connection parts 31a and a pair of first relay connection parts 51a and first relay connection parts 51b electrically connected to the connection parts 31a. The conversion device 50 also has a second relay connection part 52 electrically connected to the pin 41.

[0046]

[0027] As described above, the saddle-riding vehicle device 20 configured in this manner can reduce the installation space for the communication line 110 compared to conventional devices. Furthermore, as described above, the saddle-riding vehicle device 20 configured in this manner can be made smaller than, for example, conventional saddle-riding vehicle devices, and the installation space for the saddle-riding vehicle device 20 itself can also be reduced. Therefore, the saddle-riding vehicle device 20 configured in this manner can reduce the installation space when mounted on the saddle-riding vehicle 100.

[0047]

[0028] The saddle-riding type vehicle device 20 configured as described above can also achieve the following effects. Two communication lines for balanced communication need to be configured with a diverging connection. On the other hand, the saddle-riding type vehicle device 20 according to this embodiment can communicate using a single communication line 110, eliminating the need to diverge the communication line and allowing the use of an inexpensive communication line 110. Therefore, by installing the saddle-riding type vehicle device 20 according to this embodiment in a saddle-riding type vehicle 100, the manufacturing cost of the saddle-riding type vehicle 100 can be reduced. Furthermore, the saddle-riding type vehicle device 20 according to this embodiment can reduce the number of communication lines installed between devices, thereby reducing the weight of the saddle-riding type vehicle 100.

[0048]

[0029] Since the saddle-riding vehicle 100 has a smaller body than other vehicles (for example, four-wheeled automobiles), the distance between the devices mounted on the saddle-riding vehicle tends to be relatively short. Therefore, even when the saddle-riding vehicle device 20 according to this embodiment communicates with the external device 200 using unbalanced communication, it is possible to ensure communication quality equivalent to that when communication is performed using balanced communication.

[0049] [ 0 0 3 0 ]

[0050] <Modification> Fig. 3 is a diagram illustrating a modification of the saddle-riding type vehicle device according to an embodiment of the present invention. In a saddle-riding type vehicle equipped with conventional saddle-riding type vehicle devices that perform balanced communication, when the communication volume between the devices is relatively large and the communication capacity of only two communication lines is insufficient, or when multiple communication systems are required, multiple sets of two communication lines may be prepared and the saddle-riding type vehicle devices may be electrically connected to each communication line. In the saddle-riding type vehicle 100 according to this embodiment, when the communication volume between the saddle-riding type vehicle device 20 and the external device 200 is greater than the communication capacity of a single communication line 110, or when multiple communication systems are required, the saddle-riding type vehicle device 20 is electrically connected to each of the multiple communication lines 110. In such a case, the saddle-riding type vehicle device 20 is configured as shown in Fig. 3. In addition, Figure 3 shows an example in which a saddle-type vehicle device 20 is electrically connected to two communication lines 110.

[0051]

[0031] Specifically, the saddle-riding type vehicle device 20 includes a plurality of conversion devices 50. The control device 30 includes a plurality of pairs of connection portions 31a and 31b. Each of the conversion devices 50 is connected to a different pair of connection portions 31a and 31b. A saddle-riding type vehicle equipped with conventional saddle-riding type vehicle devices that perform balanced communication requires twice as many communication lines as the communication line 110. In other words, a saddle-riding type vehicle 100 equipped with the saddle-riding type vehicle device 20 according to this embodiment only needs to have half the number of communication lines 110 compared to the number of communication lines required in a conventional saddle-riding type vehicle. Therefore, in the saddle-riding type vehicle device 20 according to this embodiment, the greater the number of communication lines 110 that electrically connect the saddle-riding type vehicle device 20 and the external device 200, the greater the above-mentioned effect.

[0052]

[0032] Fig. 4 is a diagram illustrating a modified example of the saddle-riding type vehicle equipment according to the embodiment of the present invention. The saddle-riding type vehicle equipment 20 may include a plurality of control devices 30 for controlling different control targets. For example, if the saddle-riding type vehicle equipment 20 is an integrated unit of a hydraulic control unit and an engine control unit, the saddle-riding type vehicle equipment 20 will include a control device 30 that controls an on-off valve (not shown) of at least one of the first hydraulic pressure circuit 12 and the second hydraulic pressure circuit 14, and a control device 30 that controls the output of the engine 5. In such a case, the saddle-riding type vehicle equipment 20 may be configured as shown in Fig. 4.

[0053]

[0033] Specifically, the saddle-riding type vehicle device 20 includes a plurality of control devices 30. The pair of connection portions 31a and 31b of at least two of the plurality of control devices 30 are connected to the same pair of first relay connection portions 51a and 51b of the conversion device 50. In this way, the saddle-riding type vehicle device 20 can be configured to convert balanced communication signals output from the plurality of control devices 30 and input to the first relay connection portion 51a into unbalanced communication signals and output them from the second relay connection portion 52. Even with this configuration, the above-mentioned effects can be obtained.

[0054]

[0034] The saddle-riding type vehicle equipment 20 described above is equipment mounted on the saddle-riding type vehicle 100. However, the saddle-riding type vehicle equipment 20 is not limited to equipment mounted on the saddle-riding type vehicle 100. For example, the saddle-riding type vehicle equipment 20 may be equipment electrically connected to equipment mounted on the saddle-riding type vehicle 100. For example, the saddle-riding type vehicle equipment 20 may be an inspection equipment electrically connected to equipment mounted on the saddle-riding type vehicle 100 and inspecting that equipment. In other words, inspection equipment that inspects the saddle-riding type vehicle equipment 20 mounted on the saddle-riding type vehicle 100 can also be the saddle-riding type vehicle equipment 20. The saddle-type vehicle device 20 as an inspection device can be made smaller by reducing the number of pins 41 of the connector 40.

[0055]

[0035] Although the saddle-riding type vehicle device 20 according to this embodiment has been described above, the saddle-riding type vehicle device according to the present invention is not limited to the description of this embodiment, and only a part of this embodiment may be implemented.
