(Linked change display control)
The display of each display unit may be changed by the control device 5 in conjunction with the change of the distribution ratio for one function received by one operation unit from the user. This case will be described with reference to FIG. To do. For convenience, the flowchart will be described with reference to one flowchart. However, event-driven control in which the control device 5 executes processing one by one in accordance with instructions received from the user may be used.

  The control device 5 executes the control shown in FIG. The control device 5 determines whether or not the first operation unit has received an operation for increasing the distribution ratio for the travel function from the user (step S300). When the control device 5 determines that the first operation unit has accepted the increase operation, the control device 5 proceeds to step S301.

  In step 301, the control device 5 performs display control in which the first display unit increases the possible amount of the traveling function according to the operation amount received from the user by the first operation unit. Next, the process proceeds to step S302. If the control device 5 does not determine that it has been received, the control device 5 proceeds to step S304.

  In step 302, the control device 5 converts the displayable amount of the traveling function, which is changed and displayed on the first display unit, into electric power, and calculates how much the electric power is distributed in the remaining electric power. In the distribution ratio, an amount that is larger than the distribution ratio before the change is reduced in the distribution ratio for the audio function and the distribution ratio for the air conditioning function. The reduction rate is even in their function. The possible amount that can perform these functions in units corresponding to the respective functions is calculated from the distribution ratios that are uniformly reduced and the remaining power of the battery 80. The calculated displayable amounts are displayed on the second display unit and the third display unit, respectively. That is, the control device 5 displays those displayable amounts reduced from the displayable amounts before the change display on the second display unit and the third display unit, respectively. Next, the process proceeds to step S303.

  In step S303, the control device 5 integrates the distribution ratio with respect to the increased running function, the distribution ratio with respect to the equally reduced audio function, and the distribution ratio with respect to the air conditioning function in a bar indicating the remaining power of the fourth display unit. Are superimposed and displayed. Next, the process proceeds to step S304.

  In step S <b> 304, the control device 5 determines whether or not the second operation unit has received an increase operation of the distribution ratio for the audio function from the user. When the control device 5 determines that the second operation unit has accepted the increase operation, the control device 5 proceeds to step S305. If the control device 5 does not determine that it has been received, the control device 5 proceeds to step S308.

  In step 305, the control device 5 controls the second display unit to increase the possible display amount of the audio function according to the operation amount received from the user by the second operation unit. Next, the process proceeds to step S306.

  In step 306, the control device 5 converts the displayable amount of the audio function, which is changed and displayed on the second display unit, into power, and calculates how much the power is distributed in the remaining power. In the distribution ratio, an amount that is larger than the distribution ratio before the change is decreased in the distribution ratio for the air conditioning function. At this time, the distribution ratio for the running function is maintained without being reduced. From the distribution ratio with respect to the reduced audio function, the distribution ratio with respect to the decreased air conditioning function, and the remaining power of the battery 80, the possible amount that can perform these functions in units corresponding to the audio function and the air conditioning function is calculated. The calculated displayable amounts are displayed on the second display unit and the third display unit, respectively. That is, the control device 5 displays the displayable amounts increased and decreased from the displayable amount before the change display on the second display unit and the third display unit, respectively. Next, the process proceeds to step S307.

  In step S307, the distribution ratio with respect to the increased audio function and the distribution ratio with respect to the decreased air conditioning function are integrally superimposed on the bar indicating the remaining power on the fourth display unit. Next, the process proceeds to step S308.

  In step S308, the control device 5 determines whether or not the third operation unit has received an increase operation of the distribution ratio for the air conditioning function from the user. When the control device 5 determines that the third operation unit has accepted the increase operation, the control device 5 proceeds to step S309. If the control device 5 does not determine that it has been received, the control device 5 proceeds to return.

  In step 309, the control device 5 performs display control for increasing the possible amount of the air conditioning function according to the operation amount that the user has increased the third operation unit on the third display unit. Next, the process proceeds to step S310.

  In step 310, the control device 5 converts the displayable amount of the air-conditioning function displayed on the third display unit into electric power, and calculates how much the electric power is distributed in the remaining electric power. In the distribution ratio, an amount that is larger than the distribution ratio before the change is decreased in the distribution ratio for the audio function. At this time, the distribution ratio for the running function is maintained without being reduced. From the distribution ratio with respect to the increased air conditioning function, the distribution ratio with respect to the decreased audio function, and the remaining power of the battery 80, the possible amount that can perform these functions in units corresponding to the audio function and the air conditioning function is calculated. The calculated displayable amounts are displayed on the second display unit and the third display unit, respectively. That is, the control device 5 displays those displayable amounts that are reduced and increased from those displayed before the change display on the second display unit and the third display unit, respectively. Next, the process proceeds to step S311.

  In step S311, the distribution ratio with respect to the reduced audio function and the distribution ratio with respect to the increased air conditioning function are integrally superimposed on the bar indicating the remaining power on the fourth display unit.

  By executing such interlocking change display control, the control device 5 does not decrease the distribution ratio to the travel function when there is a user instruction to change the distribution ratio related to one function other than the travel function. In addition, by changing and adjusting the distribution ratio for other functions, the distribution ratio for driving functions that are highly important in the vehicle is changed by changing the distribution ratio of other less important functions. This eliminates the need for readjustment and eliminates unnecessary labor.

  The router 17 is a device that relays data between networks having a known function.

  The personal computer 16 is a computer having a known function.

  The power distribution terminal 15 has a function of remotely controlling the power distribution of the power distribution system mounted on the vehicle 3 via the indoor network 101, the charging cable, and the charging device 4. The power distribution terminal 15 includes a first display unit 21X, a first operation unit 20X, a second display unit 31X, a second operation unit 30X, a third display unit 41X, a third operation unit 40X, a mode change switch 91, and a first 5 display unit 19 is provided.

  The power distribution terminal 15 can perform power distribution as described above by remote operation. The display on the fourth display unit in the power distribution system mounted on the vehicle 3 functions in the fifth display unit 19 of the power distribution terminal 15. Further, when the mode change switch 91 accepts a mode change from the user, the power distribution terminal 15 changes to a mode in which various settings convenient for the user can be executed in addition to the mode for setting the power distribution as described above. . Various settings include the setting of charging start / end times, the initial setting (map data linkage initial setting) for setting the distribution ratio for the running function in association with the map data, and the power distribution stored for each user in advance. There are initial settings to be set (initial settings by user).

(Map data linkage initial setting)
The map data linkage initial setting will be described with reference to FIG. The power distribution terminal 15 receives a destination setting from the user (step S400). As shown in FIG. 11, the destination is displayed on the fifth display unit 19 of the power distribution terminal via the Internet or the map data acquired from the personal computer 16 and the battery 80 mounted on the vehicle 3. Based on the cruising range calculated based on the remaining power, the first range 202 that can start from the current location 201 and return to the current location 201, the second range 203 that cannot be reached but can be reached, and difficult to reach A third range 204 is displayed. In addition, when the power distribution terminal 15 displays the first range, the second range, and the third range, the power distribution terminal 15 calculates the minimum amount of power required for the vehicle 3 to travel from the distance indicated by the ranges, The amount of power calculated beside each range is displayed on the fifth display unit 19. Further, the remaining power amount of the battery 80 mounted on the vehicle 3 is also displayed on the fifth display unit 19 as a bar. Thereby, the user can grasp which range of distance on the map can be moved back with the remaining power of the battery mounted on the vehicle, how far it can reach, and what cannot be reached. Next, the process proceeds to step S401.

  In step S401, the power distribution terminal 15 performs display control by changing, on the first display unit 21X, the possible amount of the traveling function according to the operation amount received by the first operation unit 20X from the user. Next, the process proceeds to step S402.

  In step 402, the power distribution terminal 15 converts the displayable amount of the traveling function, which is changed and displayed on the first display unit 21X, into electric power, and calculates how much the electric power is distributed in the remaining electric power. Based on the distribution ratio, the remaining distribution ratio is allocated equally by the distribution ratio for the audio function and the distribution ratio for the air conditioning function. From the distribution ratio and the remaining power of the battery 80, the possible amount that can be exhibited in the unit corresponding to each function is calculated. The calculated displayable amounts are displayed on the second display unit 31X and the third display unit 41X, respectively. The process proceeds to step S403.

  In step S403, the power distribution terminal 15 sends the remaining power to the fifth display unit 19 with the distribution ratio for the traveling function received from the user, the distribution ratio for the air conditioning function allocated evenly, and the distribution ratio for the audio function. In the bar shown, it is superimposed and displayed integrally.

  By providing such a map data linkage initial setting function, the user can obtain a sense of security that the remaining power of the battery 80 mounted on the vehicle can travel a distance that can reach the destination, etc. In the above, it is possible to know how much the audio function and the air-conditioning function that are less important than the driving function that is more important can be used.

(Initial setting for each mode)
The initial setting for each mode will be described with reference to FIG. The power distribution terminal 15 receives a mode setting from the user (step S500). In the mode setting, the power distribution terminal 15 initially sets each distribution ratio for each function according to the mode received by each operation unit 21, 31, 41. For example, the power distribution terminal 15 stores in advance a distribution ratio for each function for each user (father mode, mother mode, brother mode, sister mode, brother mode, etc.) in the storage unit, and the user name received from the operation unit The distribution ratio corresponding to is read from the storage unit and set. Next, the process proceeds to step S501.

  In step S <b> 501, the power distribution terminal 15 performs display control on the first display unit 21 </ b> X for the possible amount of the traveling function according to the mode accepted by the arbitrary operation unit from the user. Next, the process proceeds to step S502.

  In step 502, the power distribution terminal 15 performs display control on the first display unit 31X of the audio function possible amount corresponding to the mode accepted by the arbitrary operation unit from the user. Next, the process proceeds to step S503.

  In step S503, the power distribution terminal 15 controls the first display unit 41X to display the possible amount of the air conditioning function according to the mode accepted by the arbitrary operation unit from the user. Next, the process proceeds to step S504.

  In step S504, the power distribution terminal 15 sends the remaining power to the fifth display unit 19 with the distribution ratio for the traveling function received from the user, the distribution ratio for the air conditioning function allocated evenly, and the distribution ratio for the audio function. In the bar shown, it is superimposed and displayed integrally.

  By providing such an initial setting function for each mode, it is possible to save the trouble of having to set the distribution ratio according to the specifications each time the vehicle 3 is used.

<Modification 1>
The interlock change display control in the above representative embodiment is performed without reducing the distribution ratio to the travel function when the control device 5 has a user instruction to change the distribution ratio related to one function other than the travel function. As long as the distribution ratio relating to other functions is changed and adjusted, the following interlock change display control may be used.

  When the controller 5 is operated to increase the amount of the first operation unit 20, the distribution ratio for the running function is increased according to the increase, and the distribution ratio corresponding to the increase is set to the distribution ratio for the audio function, or Only one of the distribution ratios for the air conditioning function is adjusted to be small.

  When the control device 5 is operated to increase the amount of the first operation unit 20, the distribution ratio for the running function is increased according to the increase amount, and the distribution ratio for the increase amount is set to 7 for the audio function. And adjust the distribution ratio to the air conditioning function by decreasing it by 3.

  When the control device 5 is operated to reduce the amount of the second operating unit 30, the distribution ratio for the audio function is reduced according to the reduction amount, and the distribution ratio for the reduction amount is increased to the distribution ratio for the running function. And adjust.

  When the control device 5 is operated to reduce the amount of the third operating unit 40, the distribution ratio for the air conditioning function is reduced according to the reduction, and the distribution ratio for the reduction is increased. And adjust.

  That is, in other words, when there is a user instruction to change the distribution ratio related to one function other than the traveling function, the control device 5 maintains or increases the distribution ratio to the traveling function without decreasing it. Thus, the distribution ratio for other functions may be changed and adjusted. Therefore, the distribution ratio for the driving function, which is a function with high importance in the vehicle, is not reduced by changing the distribution ratio of other functions with low importance, and re-adjustment is unnecessary, thus saving unnecessary time. be able to.

<Modification 2>

  The operation unit 40 is configured by a belt-like ring surrounding the display unit 41. The belt-like ring is provided with an electrostatic sensor, and the electrostatic sensor senses when a user's finger touches it, and transmits a signal at the time of sensing to the control device 5. The operation unit 40 has a function of accepting a change in the operation amount for a predetermined function from the user. Therefore, the amount of movement can be increased or decreased when the user touches the band-like ring with a finger. More specifically, the movement amount is increased or decreased according to the area of the belt-shaped ring touched by the user's finger, and the movement amount increases when the belt-shaped ring is touched clockwise, and the movement amount when the counterclockwise touch is touched.

A gauge 43 is displayed on the edge of the circular display. More specifically, the gauge 43 increases in accordance with the amount of the area of the belt-like ring of the operation unit 40 touched by the user's finger, and the gauge 43 increases when the belt-like ring is touched clockwise. Conversely, when the operation unit 40 accepts a set temperature reduction operation from the user, the control device 5 displays the gauge 43 indicating the decrease state on the edge of the circular display unit. More specifically, the gauge 43 decreases according to the amount of the area of the belt-shaped ring of the operation unit 40 touched by the user's finger, and the gauge 43 decreases when the belt-shaped ring is touched counterclockwise.

  When the control device 5 performs such operation control and display control, the user can easily set a level such as a set temperature or a volume while concentrating on driving. That is, since the user operates the operation unit 40 using the electrostatic sensor, it can be operated by a blind touch, and the operation result is displayed on the display unit 41 in the vicinity of the operation unit 40, and Since the level display is changed according to the operation amount of the user's finger, the setting operation can be performed without wasteful search for the display of the operation result.
