  FIG. 4 shows a flow chart of the operation of the display operation unit 40, the motor unit 20 and the air conditioner unit 60.

  First, the passenger turns on / off the power switch 48 in step S11. In addition, the present condition is maintained when not operated. If the power supply SW 48 is off, the process proceeds to step S12 to cut off the power supply from the battery unit 30 to each unit including the display operation unit 40. When the power supply SW 48 is turned on, the power supply to the units including the display operation unit 40 from the battery unit 30 is started, and the process proceeds to step S13.

  In step S13, the passenger turns on / off the illumination SW 43. In addition, the present condition is maintained when not operated. If the illumination SW 43 is turned on, the process proceeds to step S14 to illuminate the illuminator 10. If the illumination SW 43 is turned off, the process proceeds to step S15 to turn off the illuminator 10. The process proceeds to step S16 regardless of the operation of the illumination SW 43.

  In step S16, the passenger turns on / off the assist switch 44. In addition, the present condition is maintained when not operated. If the assist switch 44 is turned off, the process proceeds to step S17, and power assistance from the motor unit 20 is not performed. If the assist switch 44 is turned on, the process proceeds to step S18, and the power assist ratio of the assist power is selected from the three types, for example, powerful, automatic, and save, using the selection SW 45a, 45b. One of the mode indicator lights 49a, 49b, 49c is turned on by the operation of the selection SW 45a, 45b to indicate the selected power assist ratio. As an example of a power assistance rate, it is 60 to 80% in powerful, 40 to 60% in automatic, and 20 to 40% in save.

  After selecting the power assist ratio, the process proceeds to step S19, where the motor unit 20 transmits power to the crankshaft 15 so as to achieve the selected power assist ratio. It transfers to step S20 irrespective of the presence or absence of operation of assist SW44.

  In step S20, the passenger turns on / off the air conditioner switch 46. In addition, the present condition is maintained when not operated. If the air conditioner switch 46 is turned off, the process proceeds to step S21 to stop the air conditioner unit 60. If the air conditioner switch 46 is turned on, the process proceeds to step S22, and the power ratio of the air conditioner unit 60 is selected from the three types of powerful, automatic, and save using the selection switches 45a and 45b.

  One of the mode indicator lights 49a, 49b, 49c is turned on by the operation of the selection SW 45a, 45b to indicate the selected capacity ratio.

  Next, the process proceeds to step S23, and the current traveling speed of the electric bicycle 1 with an air conditioner is measured by the speed sensor 47. When the traveling speed is higher than V, the air conditioner ON / OFF means 63 stops the air conditioner unit 60. When the traveling speed is lower than V, the air conditioner ON / OFF means 63 operates the air conditioner unit 60.

  At step S25, the capacity control means 64 operates the air conditioner unit 60 at a predetermined capacity ratio according to the capacity ratio selected by the selection SW 45a, 45b and the traveling speed V measured by the speed sensor 47.

  An example of the traveling speed and capacity ratio of the electric bicycle 1 with an air conditioner will be described with reference to FIG.

  FIG. 5 is a view showing the relationship between the traveling speed and the capacity ratio of the electric bicycle 1 with an air conditioner.

  The horizontal axis represents the traveling speed of the electric bicycle 1 with air conditioning, and the vertical axis represents the capacity ratio of the air conditioning unit 60 when the maximum capacity of the air conditioning unit 60 can be 100%. Also, the relationship between the running speed and the ability ratio of the powerful, automatic and save selected using the selection SW 45a and 45b is shown.

  From FIG. 5, when the traveling speed exceeds Vkm / h, the capacity ratio of the air conditioner unit 60 becomes 0%. That is, it will stop. Further, in any of the powerful, automatic and save cases, the capacity ratio of the air conditioner unit 60 is reduced as the traveling speed increases. The reduction ratio to the traveling speed is powerful <automatic <save. Further, the traveling speed of the air-conditioned electric bicycle is 0 km / h, that is, while the vehicle is stopped, the capacity ratio of the air conditioning unit 60 is 100%.

  Thus, the capacity control means 64 operates the air conditioner unit 60 at a predetermined capacity ratio, based on the capacity ratio selected by the selection SW 45 a and 45 b and the traveling speed V measured by the speed sensor 47.

  When the air conditioner switch 46 is turned on in step S20, the monitoring of steps S22, S23, S24 and S25 is always performed to operate the air conditioner unit 60 so as to meet the respective conditions.

  Next, in step S26, the passenger operates the display switching SW 71. In addition, the present condition is maintained when not operated. If the display switching SW 71 is turned off, the process proceeds to step S 27 and the display of the liquid crystal display 70 is stopped.

  When the display switching SW 71 is operated to shift to step S 28, the passenger can select any display and display it on the liquid crystal display 70. An example of the display content is the remaining amount of battery 32, traveling speed, traveling distance, time, map, air temperature of outlet 61 (temperature sensor is not shown), etc. These are switched by the operation of display switching SW 71 liquid crystal display It is displayed on 70.

  Thereafter, the process returns to step S11 to detect ON / OFF of the power switch 48, and the display operation unit control unit 41 constantly monitors the above flow until the passenger turns off the power switch 48, in accordance with the operation of the passenger. Control each unit.

  As described above, since the electric motorcycle suppresses the capability of the air conditioner unit 60 according to the traveling speed, it is possible to suppress the power consumption of the battery unit 30 without losing the comfort. That is, since the rider can usually feel the flow of air while riding a bicycle, the flow of air hitting the body becomes faster in proportion to the increase in speed, and the feeling of coolness is improved. Therefore, when the traveling speed is high, the comfort is not impaired even if the ability of air conditioner unit 60 is suppressed, so when the air flow is felt like this, the drive of air conditioner unit 60 is limited to power the battery unit 30. Consumption can be reduced. In addition, when the traveling speed is low, the air conditioning unit 60 can be driven to ensure comfort with the air from the air conditioning unit 60 instead of the flow of air.

  In other words, when the traveling speed of the air-conditioned electric bicycle 1 becomes lower than a predetermined speed and the passenger can not feel the flow of air, it can supply cold air to improve the comfort while the traveling speed is constant. When the speed is increased and the passenger can feel the flow of air and can maintain a certain degree of comfort, the air conditioner can be stopped to suppress the power consumption of the battery unit 30, and the comfort and It is possible to efficiently achieve both energy saving performance.

  Although the above embodiment is described on the premise that cold air is blown out from the outlet 61 particularly in summer, and switching between cold air and warm air is not described, but the air conditioner 62 is a cooling switching air conditioner and the passenger Switching may be performed using a cold / warm air switching SW, or environmental temperature may be detected using a temperature sensor and switching may be performed according to the temperature. For example, when a refrigeration cycle is used as the air conditioner 62, a four-way valve is used as a cooling / heating switching type air conditioner, and when a Peltier element is used, a circuit capable of reversing the plus and minus of the applied power is provided. Just do it.

  Further, the electric bicycle 1 with an air conditioner according to the present embodiment includes the display operation unit 40 capable of displaying the remaining amount of the battery unit 30, and the capacity control means 64 is a power ratio of the motor unit 20 and a capacity ratio of the air conditioner unit 60. The adjustment of the auxiliary power ratio of the motor unit 20 and the capacity ratio of the air conditioner unit 60 while checking the remaining amount of the battery unit 30 to make the balance between the comfort and the energy saving efficiency more efficiently. Can be achieved.

  Further, if the air conditioning unit 60 is configured using a refrigeration cycle equipped with a compressor, the electric bicycle 1 with air conditioning can perform strong cooling or heating by the refrigeration cycle, effectively improving comfort. be able to.

  Further, if the air conditioner unit 60 is configured using a Peltier element, the air conditioner unit itself can be compactly assembled, and a compact, easy-to-use electric bicycle with an air conditioner can be obtained.

As mentioned above, although the electric motorcycle with an air-conditioner concerning the present invention has been explained using the above-mentioned embodiment, the present invention is not limited to this, and can be variously changed in the range which attains the object of the present invention It goes without saying that there is one.

  For example, in this embodiment, an electric bicycle carrying a battery as an auxiliary power source for traveling is described as an example of a two-wheeled vehicle, but the present invention is not limited to such an electric bicycle, and a battery for traveling is provided. It may be an electric motorcycle.

  In addition, even a normal bicycle that does not have a battery serving as an auxiliary power source during traveling, such as an electric bicycle, is a bicycle in which a battery is separately installed and the air conditioner is driven by the battery. Is also good.

  Furthermore, even a motorcycle using an engine as a driving power source can drive an air conditioner with a battery mounted thereon, and therefore, such a battery mounted engine type motorcycle may be used. .

  In addition, the number of wheels may be a bicycle, an electric motorcycle, or a battery-mounted engine type motorcycle having a total of three wheels with one of the rear wheels or the front wheels as two wheels, and in the present invention, such three wheels The type is also defined as a two-wheeler and is included in that range.
