Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, when it is necessary to leave the vehicle for a short time even though the charging of the portable terminal is not complete, there may be a desire to supply power to the portable terminal even while the engine is stopped. However, if the configuration allows power supply even while the engine is stopped, there is a problem that a third party can use the power supply device while the user is away from the vehicle. Patent Document 1 did not consider power supply control that can address such desires and problems.

[0006] An object of the present invention is to provide a saddle-type vehicle that can solve the above problems of the prior art and can achieve both power supply to a portable terminal while the engine is stopped and prevention of use of the power supply device by a third party.

Means for Solving the Problem

[0007] In order to achieve the above object, the present invention provides a saddle-type vehicle (1) having a battery (B) charged with the electric power generated by a generator (G) driven by an engine (E), and a power supply device (31) for supplying the power of the battery (B) to a portable terminal (30). The power supply device (31) is provided with a power supply control unit (33) for controlling the power supply device (31). The power supply control unit (33) determines whether the portable terminal (30) is in a power supply state when the engine (E) stops following the OFF operation of an ignition switch (34). If it is in a power supply state, the power supply is continued; if not, the power supply is prohibited. This is the first feature.

[0008] Further, when the voltage of the battery (B) becomes equal to or lower than a predetermined threshold value while the power supply to the portable terminal (30) is being continued, the power supply control unit (33) stops the power supply to the portable terminal (30). This is the second feature.

[0009] Further, when the time elapsed since the engine (E) stopped reaches a predetermined time while the power supply to the portable terminal (30) is being continued, the power supply control unit (33) stops the power supply to the portable terminal (30). This is the third feature.

[0010] The saddle-type vehicle (1) further includes a luggage box (17) having an opening / closing lid, and a luggage box opening / closing detection means (24) for detecting the opening / closing state of the luggage box (17). The luggage box opening / closing detection means (24) transmits the opening / closing state of the luggage box (17) to the power supply control unit (33). When the luggage box (17) is in an open state while the power supply to the portable terminal (30) is being continued, the power supply control unit (33) stops the power supply to the portable terminal (30). This is the fourth feature.

[0011] Furthermore, it includes a handle lock (21) that prohibits rotation of the steering handle (2), and a handle lock locking detection means (22) that detects the locked state of the handle lock (21). The handle lock locking detection means (22) transmits the locked state of the handle lock (21) to the power supply control unit (33). The power supply control unit (33) stops power supply to the mobile terminal (30) when the handle lock (21) is in the locked state while power supply to the mobile terminal (30) is continuing, which is the fifth feature.

Advantages of the Invention

[0012] According to the first feature, in a saddle-ride type vehicle (1) having a battery (B) charged with the electric power generated by a generator (G) driven by an engine (E), and a power supply device (31) that supplies the power of the battery (B) to a mobile terminal (30), it includes a power supply control unit (33) that controls the power supply device (31). When the engine (E) stops following an off operation of an ignition switch (34), the power supply control unit (33) determines whether the mobile terminal (30) is in a power supply state. If it is in a power supply state, power supply is continued, while if it is not in a power supply state, power supply is prohibited. Therefore, for example, when temporarily stopping and leaving the vehicle for a short time, the mobile terminal connected to the vehicle's power supply device can continue to be charged. Also, since power supply is prohibited if the mobile terminal is not in a power supply state when the engine is stopped, power supply by a third party can be prevented. As a result, it becomes possible to balance the user's desire to continue power supply to the mobile terminal even after the engine is stopped and the prevention of power supply by a third party when the user leaves the vehicle with the mobile terminal.

[0013] According to the second feature, while power supply to the mobile terminal (30) is continuing, when the voltage of the battery (B) becomes equal to or lower than a predetermined threshold value, the power supply control unit (33) stops power supply to the mobile terminal (30). Therefore, it is possible to prevent the battery from overcharging due to continued power supply.

[0014] According to the third feature, while power supply to the mobile terminal (30) is continuing, when the time elapsed since the engine (E) stopped reaches a predetermined time, the power supply control unit (33) stops power supply to the mobile terminal (30), so that battery overcharge due to continuous power supply can be prevented.

[0015] According to the fourth feature, there are provided a luggage box (17) having an opening / closing lid and luggage box opening / closing detection means (24) for detecting the opening / closing state of the luggage box (17). The luggage box opening / closing detection means (24) transmits the opening / closing state of the luggage box (17) to the power supply control unit (33). While power supply to the mobile terminal (30) is continuing, when the luggage box (17) is opened, the power supply control unit (33) stops power supply to the mobile terminal (30). Thus, when the user opens the luggage box, it is possible to stop power supply on the presumption that the user will be away from the vehicle for a long time, thereby preventing battery overcharge.

[0016] According to the fifth feature, there are provided a handle lock (21) for prohibiting rotation of the steering handle (2) and handle lock locking detection means (22) for detecting the locked state of the handle lock (21). The handle lock locking detection means (22) transmits the locked state of the handle lock (21) to the power supply control unit (33). While power supply to the mobile terminal (30) is continuing, when the handle lock (21) is in the locked state, the power supply control unit (33) stops power supply to the mobile terminal (30). Thus, when the user locks the handle lock, it is possible to stop power supply on the presumption that the user will be away from the vehicle for a long time, thereby preventing battery overcharge.

Embodiments for Carrying Out the Invention

[0018] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a left side view of a motorcycle 1 according to this embodiment. The motorcycle 1 is a scooter-type saddle-riding vehicle provided with a straddle portion 18 at the center in the vehicle width direction and a pair of left and right footrest portions 10 between the steering handle 2 and the seat 16. The steering handle 2 for steering the front wheel WF is connected to a pair of left and right front forks 8 that rotatably support the front wheel WF. A rearview mirror 3 is supported on the steering handle 2, and a front fender 7 is supported on the front fork 8. A front cowl 5 that supports a windshield 4 and a headlight 6 is disposed below the front of the steering handle 2, and a leg shield 20 that stands upright facing the driver's feet is connected to the rear portion of the front cowl 5. An opening / closing lid 19 for a small item storage is disposed at a position slightly to the left in the vehicle width direction of the leg shield 20.

[0019] A unit swing-type power unit P that integrally forms an engine E and a continuously variable transmission is disposed at a position behind a side panel 9 that stands upright from the inner side in the vehicle width direction of the footrest portion 10. A rear wheel WR as a drive wheel is rotatably supported at the rear end portion of the power unit P. An air cleaner box 11 is disposed on the upper portion of the power unit P, and the rear portion of the power unit P is suspended from the vehicle body by a rear cushion 12. A generator G driven by the engine E is housed in the power unit P.

[0020] A pair of left and right rear cowls 15 are connected above and behind the side panel 9. A tail lamp device 14 and a rear fender 13 are attached to the rear end portion of the rear cowl 15. Also, a seat 16 on which a passenger sits is disposed above the rear cowl 15. The seat 16 also functions as an opening / closing lid of a luggage box 17 as a storage portion. In the vicinity of the luggage box 17, luggage box opening / closing detection means 24 for detecting the opening / closing state of the luggage box 17, that is, the opening / closing state of the seat 16, is disposed. In front of the luggage box 17, a battery B as a main battery and a sub-battery SB for power supply are disposed.

[0021] Between the front cowl 5 and the leg shield 20, a handle lock 21 for prohibiting the rotation of the steering handle 2 during parking, handle lock locking detection means 22 for detecting the locked state of the handle lock 21, and an ECU 23 as a control unit are disposed. The motorcycle 1 according to the present embodiment has a power supply device 31 disposed inside a small-item storage accessed by opening the opening / closing lid 19, and is configured to be able to charge a portable terminal 30 such as a smartphone stored in the small-item storage. The power supply device 31 may be composed of a connector and a harness connected to the portable terminal 30, or may be a non-contact power supply device.

[0022] FIG. 2 is a block diagram showing the configuration of a power supply system for a portable terminal according to the present embodiment. The same reference numerals as above indicate the same or equivalent parts. Power is supplied from the sub-battery SB for power supply to a power supply device 31 for charging the portable terminal 30. The mode of power supply to the portable terminal 30 is controlled by a power supply control unit 33 included in the ECU 32. The power supply control unit 33 is configured to detect whether power is being supplied to the portable terminal 30 by the power supply device 31, that is, whether it is in a power supply state, and to be able to change the mode of power supply.

[0023] The battery B is charged with the electric power generated by the generator G driven by the engine E. The power supply sub-battery SB is charged with the power of the battery B while the ignition switch 34 that turns on and off the main power supply of the motorcycle 1 is on. Output signals from the handle lock locking detection means 22 and the luggage box opening / closing detection means are input to the ECU 32. Note that it may be configured to supply power directly from the battery B to the power supply device 31 without having the power supply sub-battery SB. Further, the portable wireless key 35 capable of wireless communication with the ECU 32 enables control such as permitting the on-operation of the ignition switch 34 only when mutual communication between the portable wireless key 35 and the ECU 32 is possible.

[0024] In the present embodiment, the power supply control unit 33 determines whether the portable terminal 30 is in a power supply state when the engine E stops with the ignition switch 34 turned off. If it is in the power supply state, the power supply to the portable terminal 30 is continued, while if it is not in the power supply state, the power supply to the portable terminal 30 is prohibited. Thereby, for example, when temporarily stopping and leaving the motorcycle 1 for a short time, it becomes possible to continue charging the portable terminal 30 connected to the power supply device 31. Also, since power supply is prohibited if not in the power supply state when the engine E stops, power supply by a third party can be prevented. As a result, it becomes possible to balance the user's desire to continue power supply to the portable terminal 30 even after the engine E stops and the prevention of power supply by a third party when the user leaves the motorcycle 1 while holding the portable terminal 30.

[0025] Figure 3 is a flowchart showing the procedure of the portable terminal power supply control 1. In step S1, the ignition switch 34 is turned off. In step S2, the power supply control unit 33 determines whether the portable terminal 30 is in a power supply state. If an affirmative determination is made in step S2, the process proceeds to step S3 and the power supply is continued. On the other hand, if a negative determination is made in step S2, that is, if the portable terminal 30 is not in a power supply state when the ignition switch 34 is turned off, the process proceeds to step S8, the power supply is prohibited, and a series of controls ends.

[0026] In step S4, it is determined whether the voltage of the battery B is equal to or lower than a predetermined threshold value (for example, 80%). If a negative determination is made in step S4, the process proceeds to step S5 to determine whether a predetermined time (for example, 30 minutes) has elapsed since the engine E stopped. If a negative determination is made in step S5, the process proceeds to step S6 to continue power supply and end the series of controls. On the other hand, if an affirmative determination is made in steps S4 and S5, the process proceeds to step S7 to stop the power supply and end the series of controls, respectively.

[0027] As described above, when the engine E stops, the power supply control unit 33 according to the present embodiment continues power supply if the mobile terminal 30 is in a power supply state, and prohibits power supply if it is not in a power supply state. Therefore, it is possible to balance the user's desire to continue power supply to the mobile terminal 30 even after the engine E stops and the prevention of power supply by a third party when the user holds the mobile terminal 30 and leaves the motorcycle 1.

[0028] In addition, when the power supply control unit 33 continues power supply even after the engine E stops, the power supply is stopped when the voltage of the battery B becomes equal to or lower than a predetermined threshold value, or when the time elapsed since the engine E stopped reaches a predetermined time. Therefore, it is possible to prevent the battery of the battery B from overcharging.

[0029] FIG. 4 is a flowchart showing the procedure of mobile terminal power supply control 2. In step S10, the ignition switch 34 is turned off. In step S11, the power supply control unit 33 determines whether the mobile terminal 30 is in a power supply state. If an affirmative determination is made in step S11, the process proceeds to step S12 to continue power supply. On the other hand, if a negative determination is made in step S11, that is, if the mobile terminal 30 is not in a power supply state when the ignition switch 34 is turned off, the process proceeds to step S18 to prohibit power supply and end the series of controls.

[0030] In step S13, it is determined whether or not the luggage box 17 has been opened by the luggage box opening / closing detection means 24. If a negative determination is made in step S13, the process proceeds to step S14, where it is determined whether or not the voltage of the battery B is equal to or lower than a predetermined threshold value. If a negative determination is made in step S14, the process proceeds to step S15, where it is determined whether or not a predetermined time has elapsed since the engine E stopped. If a negative determination is made in step S15, the process proceeds to step S16, where power supply is continued and a series of controls are terminated. On the other hand, if an affirmative determination is made in steps S13, S14, and S15, the process proceeds to step S17, where power supply is stopped and a series of controls are terminated. According to the determination in step S13, when the user opens the luggage box 17, it is possible to stop power supply on the presumption that the user will be away from the vehicle for a long time, thereby preventing the battery from running out.

[0031] Figure 5 is a flowchart showing the procedure of the mobile terminal power supply control 3. In step S20, the ignition switch 34 is turned off. In step S21, it is determined by the power supply control unit 33 whether or not the mobile terminal 30 is in a power supply state. If an affirmative determination is made in step S21, the process proceeds to step S22, where power supply is continued. On the other hand, if a negative determination is made in step S21, that is, if the mobile terminal 30 is not in a power supply state when the ignition switch 34 is turned off, the process proceeds to step S28, where power supply is prohibited and a series of controls are terminated.

[0032] In step S23, it is determined whether or not the steering wheel lock 21 has been locked by the steering wheel lock detection means 22. If a negative determination is made in step S23, the process proceeds to step S24, where it is determined whether or not the voltage of the battery B is equal to or lower than a predetermined threshold value. If a negative determination is made in step S24, the process proceeds to step S25, where it is determined whether or not a predetermined time has elapsed since the engine E stopped. If a negative determination is made in step S25, the process proceeds to step S26, where power supply is continued and a series of controls are terminated. On the other hand, if an affirmative determination is made in steps S23, S24, and S25, the process proceeds to step S27 in each case, where power supply is stopped and a series of controls are terminated. According to the determination in step S23, when the user locks the steering wheel lock 21, it is possible to stop power supply by presuming that the user has left the vehicle for a long time, thereby preventing the battery from running out.

[0033] FIG. 6 is a flowchart showing the procedure of the mobile terminal power supply control 4. In the above-described embodiment, when the ignition switch 34 is turned off and the engine E stops, if the mobile terminal 30 is in a charged state, power supply is continued. However, in the present embodiment, after the ignition switch 34 is turned off, power supply to the mobile terminal 30 can be started at an arbitrary timing by operating the mobile wireless key 35, which is a characteristic point.

[0034] In step S30, the ignition switch 34 is turned off. In step S31, it is determined whether or not there has been an operation of the mobile wireless key 35. The mobile wireless key 35 can be provided with a switch for instructing the start of power supply. If an affirmative determination is made in step S31, the process proceeds to step S32, where power supply is started. On the other hand, if a negative determination is made in step S31, the process proceeds to step S36, where power supply is prohibited.

[0035] In the subsequent step S33, it is determined whether the voltage of the battery B is equal to or lower than a predetermined threshold value. If a negative determination is made in step S33, the process proceeds to step S34 to determine whether a predetermined time has elapsed since the engine E stopped. If a negative determination is made in step S33, the process proceeds to step S35 to continue power supply and end the series of controls. On the other hand, if an affirmative determination is made in steps S33 and S34, the process proceeds to step S37 to stop the power supply and end the series of controls. Note that the power supply can be arbitrarily stopped by operating the mobile wireless key 35 while the power supply to the mobile terminal 30 is being continued.

[0036] As described above, according to the power supply control device for a mobile terminal according to the present invention, the power supply control unit 33 determines whether the mobile terminal 30 is in a power supply state when the engine E stops following an off operation of the ignition switch 34. If it is in a power supply state, the power supply is continued, while if it is not in a power supply state, the power supply is prohibited. Therefore, it is possible to balance the user's desire to continue power supply to the mobile terminal 30 even after the engine E stops and the prevention of power supply by a third party when the user holds the mobile terminal 30 and leaves the motorcycle 1.

[0037] Note that the form of the motorcycle, the shape and structure of the power supply device, the method for determining whether the mobile terminal is in a power supply state, the structure and arrangement position of the luggage box opening / closing detection means and the handle lock locking detection means, the setting of the predetermined threshold value of the battery voltage, the setting of the predetermined time after the engine stops, etc. are not limited to the above-described embodiment, and various modifications are possible. In the above embodiment, a vehicle having an engine as a drive source has been described, but the drive source may be a motor. The power supply control device for a mobile terminal according to the present invention is not limited to motorcycles and can be applied to various vehicles such as three-wheeled vehicles and four-wheeled vehicles.
