The cruising area calculation unit 23 calculates an area in which the host vehicle can travel based on the cruising range calculated by the cruising range calculation unit 22.

Next, the example of a display in the display part 8 of the map display apparatus 10 is shown. FIG. 4 is a diagram illustrating a display example of the map display device according to the first embodiment, and illustrates an example in which the display content is changed following the volume operation of an audio device that is a power consuming device.
When the user turns the rotary switch 4a of the audio device which is the user input unit 4 or presses the button 4b, an ellipse A indicating the cruising range displayed on the map of the display unit 8 following these operations is automatically displayed. The vehicle position O is displayed at a reduced or enlarged size. Specifically, when the rotary switch 4a is turned to the position "1" or the button 4b is pressed once, the cruising range A1 is displayed on the display unit 8 following these operations. Similarly, when the rotary switch 4a is turned to the position “2” or the button 4b is pressed twice, the cruising range A2 is displayed, and the rotary switch 4a is turned to the position “3” or the button 4b is turned three times. When pressed, the cruising range A3 is displayed. As described above, when the audio device is operated in the direction of increasing the volume, the power consumption is increased and the cruising range A is reduced.

  4 shows an example in which the cruising range A1 to A3 is displayed as an ellipse centered on the own vehicle position O, the display of the cruising range A is not limited to an ellipse, but as shown in FIG. Even if the distance that can be traveled by the own vehicle calculated by the cruising distance calculation unit 22 centered on the own vehicle position O (the cruising range D, details of the calculation method will be described later) is displayed in a circle with a radius. Good.

Next, the operation of the map display device 10 will be described. FIG. 6 is a flowchart showing the operation of the cruising range calculation unit of the map display device according to the first embodiment. The process for calculating the cruising range will be mainly described along the flowchart of FIG.
In the cruising range calculation unit 13, the input analysis unit 12 analyzes the operation input information of the user input unit 4, and uses the communication unit 9 to determine whether or not the setting of the power consuming device has been changed. Received from the acquisition unit 6 (step ST1). If it is determined in step ST1 that the setting of the power consuming device has not been changed, the process returns to step ST1 and waits. On the other hand, if it is determined in step ST1 that the setting of the power consuming device has been changed, the cruising range calculation unit 22 of the cruising range calculation unit 13 acquires the remaining energy Er from the remaining energy acquisition unit 5. Then, the energy consumption rate Ec is acquired from the energy consumption rate acquisition unit 6 (step ST3).

Here, Ec is the sum of the energy consumption per unit time of driving of the host vehicle and all the power consuming devices, and is calculated based on the following equation (1).
Ec = Ec0 + ΣEci (i = 1 to n) (1)
Ec0 is energy consumption per unit time (moving energy consumption) related to traveling of the host vehicle, and Eci (i = 1 to n) is energy consumption per unit time required for driving the power consuming device (hereinafter, referred to as “energy consumption”). (Referred to as drive energy consumption rate) and n indicate the number of power consuming devices mounted on the host vehicle. Here, the driving energy consumption rate of the power consuming device may be acquired directly from the power consuming device, or a table indicating the relationship between the setting of the power consuming device and the driving energy consumption rate at the time of the setting is held in advance. You may acquire from the said table.

Further, the cruising range calculation unit 22 acquires a constant d for the distance that can be navigated at the kinetic energy consumption rate Ec0 related to the traveling of the host vehicle from the traveling efficiency storage unit 21 (step ST4). In general, the constant d is a function of the road gradient and the traveling speed. Here, the constant d will be described as a constant value as a simple method. Next, the cruising range calculation unit 22 calculates the cruising range D that can be crushed while using the power consuming device based on the following equation (2) (step ST5).
D = d × (Er / Ec) (2)
(Er / Ec) in the above formula (2) is obtained by dividing the remaining energy Er by the energy consumption rate Ec, and represents the cruising time under the current power consumption conditions. By multiplying the constant d during the cruising time (Er / Ec) under the current power consumption conditions, D becomes the cruising distance under the current power consumption conditions. In addition, although the said Formula (2) is made into the simple calculation formula, in order to improve the precision of the cruising range D, it is good also as a calculation formula on more detailed conditions.

The cruising area calculation unit 23 travels from the cruising range D calculated in step ST5 based on the vehicle position information input from the vehicle position calculation unit 11 and the map data acquired from the map data storage unit 3. The possible range A is calculated (step ST6). The cruising range A calculated in step ST6 is output to the output control unit 14 (step ST7). Thereafter, the flowchart returns to the process of step ST1 and repeats the process described above. In this way, the cruising range A is calculated and displayed on the map data every time a change in the power consuming device is detected (see FIG. 4), so the cruising range is determined according to the energy consumption rate Ec of the host vehicle. It is possible to notify the user by changing A dynamically.
In FIG. 2, the cruising range calculation unit 13 refers to the analysis information from the input analysis unit 12 and determines whether the setting of the power consuming device has been changed via the user input unit 4. good. At this time, in FIG. 3, information from the input analysis unit 12 is input to the cruising range calculation unit 22.

  As described above, according to the first embodiment, the cruising range calculation unit 22 that calculates the cruising range D in consideration of the energy consumption (driving energy consumption rate) per unit time of the power consuming device is provided. Since it comprised as mentioned above, the cruising range which reflected the setting of the power consumption apparatus can be displayed.

  In addition, according to the first embodiment, the cruising range control unit 13 and the output control for calculating the cruising range D and the cruising range A every time the setting of the power consuming device is changed and displaying it on the map data. Since it comprised so that the part 14 might be provided, a cruising range can be made to follow a user operation of an electric power consumption apparatus, and can be displayed.

  Further, according to the first embodiment, the cruising range calculation unit 22 calculates the energy consumption rate Ec in consideration of the energy consumption rate amount (driving energy consumption rate) per unit time required for driving the power consuming device. Since it comprised as mentioned above, the cruising range which reflected the setting of the power consumption apparatus can be displayed.

  In addition to the display method shown in the first embodiment, the transmissible range is displayed when the power consuming device is operated, and the transmissible range is erased after a certain time when the operation is finished. The display may be changed so as to be inconspicuous, for example, by reducing the color. With this configuration, it is possible to confirm the cruising range when operating the power consuming device, and it is possible to make the display easy to view by not displaying the cruising range normally.

Embodiment 2. FIG.
In this Embodiment 2, the structure which calculates the cruising point along a main road from the own vehicle position based on the cruising distance D shown in the said Embodiment 1 is shown.
FIG. 7 is a block diagram showing the configuration of the map display device according to the second embodiment. The map display device 10 according to the second embodiment has the configuration described with reference to FIGS. 1 to 3 in the first embodiment, and the cruising range calculation unit 13 calculates the cruising range calculation unit 22. A cruising point calculation unit 24 that obtains a cruising point from the cruising range D is provided. In the following description, the same or corresponding parts as those of the map display device 10 according to the first embodiment are denoted by the same reference numerals as those used in the first embodiment, and the description thereof is omitted or simplified.

  The cruising point calculation unit 24 calculates the cruising point p from the cruising range D based on the own vehicle position information input from the own vehicle position calculation unit 11 and the map data acquired from the map data storage unit 3. The cruising area calculation unit 23 calculates the cruising range A from the cruising point p. The cruising range A may be a route to the cruising point p or may be within a range obtained by connecting a plurality of cruising points p with line segments. FIG. 8 shows a display example of the map display device according to the second embodiment. FIG. 8A shows a route that travels from the vehicle position to the cruising points p1, p2, p3, and p4 along the main road as a cruising range A in a tree diagram. Since the road is not a straight line, the range is narrower than the cruising range A of FIG. 5 shown in the first embodiment. In FIG. 8B, a range in which the cruising points p1, p2, p3, and p4 are connected by a straight line is displayed as a cruising range A.

Next, the operation will be described.
FIG. 9 is a flowchart showing the operation of the map display device according to the second embodiment. In the following, steps that perform the same processing as the processing shown in FIG. 6 of the first embodiment are denoted by the same reference numerals as those used in FIG. 6, and description thereof is omitted or simplified.
When the cruising range calculation unit 22 calculates the cruising range D in step ST5, the cruising range calculation unit 24 acquires the vehicle position information input from the vehicle position calculation unit 11 and the map data storage unit 3. Based on the map data, a cruising point p (p1, p2,..., Pn) is calculated from the cruising range D calculated in step ST5 (step ST11). The cruising area calculation unit 23 calculates the cruising range A from the cruising point p calculated in step ST11 (step ST12), and outputs it to the output control unit 14 (step ST7).

  In the process of step ST12, the cruising range A may be a tree diagram showing the route to the cruising point p shown in FIG. 8A, or the cruising point shown in FIG. 8B. It is good also as the range which connected by a straight line. Thus, by calculating the cruising point, it is possible to present the cruising range A with higher accuracy based on the cruising range D.

Next, a configuration is shown in which the cruising point calculation unit 24 calculates the cruising point p in consideration of the traveling efficiency of a general road and a motorway such as an expressway. Fuel consumption is improved on an automobile road without a traffic light, and the cruising point p can be set at a farther point. On the other hand, since there are restrictions on the points where parking and stopping are possible on the motorway, the cruising point p is calculated in consideration of these parking and stopping points.
FIG. 10 is a block diagram showing a configuration for calculating a cruising point in consideration of an automobile exclusive road in the map display device according to the second embodiment. When the vehicle has the same configuration as that shown in FIG. 7 described above and a dedicated road is included in at least a part of the route to the cruising point p calculated by the cruising point calculation unit 24, the driving efficiency memory unit 21 The traveling efficiency ratio d_ratio between the exclusive road and the ordinary road is acquired, and the cruising possible point p ′ in consideration of the traveling efficiency ratio d_ratio is calculated again.

Next, the operation will be described. FIG. 11 is a flowchart showing a cruising range display operation in consideration of the traveling efficiency of a general road and an automobile exclusive road in the map display device according to the second embodiment.
When the cruising range calculation unit 22 calculates the cruising range D in step ST5, the cruising range calculation unit 24 acquires the vehicle position information input from the vehicle position calculation unit 11 and the map data storage unit 3. Based on the map data, the distance information of the route along the main road is acquired from the own vehicle position on the map data (step ST21), and the distance of the route along the acquired main road does not exceed the cruising distance D, A point q that is closest to the cruising distance D is calculated (step ST22).

  Next, the cruising point calculation unit 24 determines whether or not an automobile exclusive road is included in at least a part of the route from the vehicle position to the point q (step ST23). If it is determined in step ST23 that no automobile exclusive road is included, the point q calculated in step ST22 is output to the navigable area calculation unit 23 as the navigable point p (step ST24). Thereafter, the cruising point calculation unit 24 determines whether or not the cruising point p is calculated for all the main roads (step ST25), and the cruising point p is not calculated for all the main roads in step ST25. Is determined, the process returns to step ST21 and the above-described processing is repeated. On the other hand, if it is determined in step ST25 that the reachable point p has been calculated for all the main roads, the reachable area calculation unit 23 calculates the reachable range A from the calculated reachable point p (step (ST26), it outputs to the output control part 14 (step ST7).

On the other hand, when it is determined in step ST23 that the exclusive road is included, the cruising range calculation unit 22 acquires the driving efficiency ratio d_ratio between the exclusive road and the general road from the driving efficiency acquisition unit 21. (Step ST27). The traveling efficiency ratio d_ratio can be calculated based on the following equation (3).
d_ratio = (driving efficiency on a motor vehicle) / (driving efficiency on a general road) d (3)

The cruising range calculation unit 22 calculates a new value obtained by multiplying the distance passing through the automobile exclusive road among the routes determined to include the automobile exclusive road in step ST23 by the travel efficiency ratio d_ratio based on the following equation (4). A cruising range D ′ is calculated (step ST28).
Travelable distance D '= distance of a general road route D_ippan + d_ratio distance of a motorway route D_senyou ... Formula (4)

  Further, a point q ′ whose route distance does not exceed the cruising distance D ′ and is closest to D ′ is calculated (step ST29). It is determined whether or not the point q ′ calculated in step ST29 is located on the car road (step ST30). If it is determined in step ST30 that the point q ′ is not located on the motorway, the point q ′ is set as the cruising point p (step ST31). On the other hand, if it is determined in step ST30 that the point q ′ is located on the exclusive road, it is possible to continue the parking / stopping point closest to the point q ′ located between the own vehicle position and the point q ′. The point p is set (step ST32). When the process of step ST31 or step ST32 is performed, the flowchart proceeds to the process of step ST25.

  In step ST32, when the vehicle flows into the exclusive road, the cruising point p is set on the general road in consideration of the parking and stopping points, or the interchange, the service area, the parking area, etc. on the exclusive road. It may be set to a point where parking and stopping is possible.

  FIG. 12 shows a display example in consideration of the traveling efficiency of a general road and a motor vehicle exclusive road. In FIG. 12 and the following description, the motor vehicle exclusive road will be described as an expressway. FIG. 12 (a) shows a tree shape of a route that travels from the vehicle position O to the cruising points p1, p2, p4, p5, and p6 along the main road in consideration of the driving efficiency ratio d_ratio between the highway and the ordinary road. It is displayed as a cruising range A in the figure. The cruising points p1, p2, and p4 exist on the general road and are the same as the points shown in FIG. On the other hand, since there is an expressway on the route from the vehicle position O to the cruising points p5 and p6, the driving efficiency ratio d_ratio is taken into consideration, and the cruising point is further away from the point p3 shown in FIG. 8 (a). Possible points p5 and p6 are set.

  On the other hand, when the cruising point p6 in FIG. 12A is located on the expressway and is not a legally stopable point such as an interchange or a service area, the point p6 is excluded from the cruising range A and displayed. The case is shown in FIG. The cruising possible point p5 is included in the cruising range A because it is a route that passes through the general road from the interchange. In FIG. 12C, if there is a service area (SA2) that can be parked and stopped on the expressway from the interchange to the cruising point p6, the point of the service area (SA2) is cruising point p6 ′. Is included in the cruising range A.

  As described above, according to the second embodiment, the cruising range P is calculated from the cruising range D and the cruising range A in the form of a tree diagram showing the route to the cruising range P, or the cruising point Since the region connecting P is set as the cruising range A, the cruising range with high accuracy based on the cruising range D can be calculated.

  Further, according to the second embodiment, the travel efficiency storage unit 21 that stores the travel efficiency is provided, and the cruising range D is calculated in consideration of the travel efficiency. The reflected cruising range can be calculated.

  Further, according to the second embodiment, when the own vehicle is traveling on a motorway, and the cruising point p is on the motorway, the cruising point p is set as a parking and stopping point. Since it is configured to set, it is possible to calculate the cruising range legally using the parking and stopping points.

Embodiment 3 FIG.
FIG. 13 is a block diagram illustrating a configuration of a cruising range calculation unit of the map display device according to the third embodiment. The cruising range calculation unit 13 of the third embodiment has the configuration described with reference to FIG. 3 in the first embodiment, and further includes a sunshine information acquisition unit 25 that acquires the sunset time and the sunrise time. Yes. In the following description, the same or corresponding parts as those of the map display device 10 according to the first embodiment are denoted by the same reference numerals as those used in the first embodiment, and the description thereof is omitted or simplified.

  The sunshine information acquisition unit 25 has, for example, the sunshine database shown in FIG. 14, acquires the sunset time or sunrise time at the current vehicle position with reference to the sunshine database, and the time from the current time to sunset. H1 or time H2 from the current time to dawn is calculated. FIG. 14A shows a sunset time table, in which the sunset time in a predetermined area is described for each date. FIG. 14B shows a sunrise time table, in which the sunrise time of a predetermined area is described for each date. As a different configuration of the sunshine information acquisition unit 25, the sunset time or sunrise time at the current vehicle position may be acquired via the communication unit 9 via the network.

The cruising range calculation unit 22 calculates the energy consumption rate considering the turning on or off of the headlight based on the time H1 from the current time to sunset input from the sunshine information acquisition unit 25 or the time H2 from the current time to dawn. The cruising range D is calculated by using this.
First, the case where the current time is before sunset, the headlights are turned on after the sunset time during the cruising, and the energy consumption per unit time increases will be described. In this case, the sunshine information acquisition unit 25 outputs the time H 1 from the current time to sunset to the cruising range calculation unit 22. The cruising range calculation unit 22 calculates the cruising range D that can be crushed when the headlight is turned on after H1 time, based on the following equation (5).
D = d * H1 + d * (Er-Ec * H1) / (Ec + Ec_headlight) (5)
However, the above equation (5) is applied when the cruising is possible after sunset, that is, when Er−Ec × H1> 0.

In the above formula (5), (Er−Ec × H1) represents the remaining energy after running for H1 hours. Ec_headlight is the energy consumption per unit time that increases when the headlight is turned on, and (Ec + Ec_headlight) represents the energy consumption per unit time after H1 time. By adding the energy consumption rate Ec_headlight of the headlight to the energy consumption rate Ec when the headlight is turned off (that is, not including the power consumption of the headlight), the energy consumption rate when the headlight is turned on after sunset is calculated.
Note that the cruising range D when cruising is impossible before sunset (within H1 hour), that is, when Er−Ec × H1 ≦ 0, is calculated based on the equation (2) shown in the first embodiment. Is done.

Next, a case where the current time is before dawn, the headlight is turned off after the sunrise time during cruising, and the amount of energy consumption per unit time decreases will be described. In this case, the sunshine information acquisition unit 25 outputs the time H2 from the current time to dawn to the cruising distance calculation unit 22. The cruising range calculation unit 22 calculates the cruising range D that can be crushed when the headlight is turned off after H2 hours, based on the following equation (6).
D = d * H2 + d * (Er-Ec * H2) / (Ec-Ec_headlight) (6)
However, the above formula (6) is applied when the cruising is possible after dawn, that is, when Er−Ec × H2> 0.

In the above formula (6), (Er−Ec × H2) represents the remaining energy after running for H2 hours. Ec_headlight is an energy consumption rate that decreases when the headlight is turned off, and (Ec-Ec_headlight) represents the energy consumption rate after H2 hours. By subtracting the energy consumption rate Ec_headlight of the headlight from the energy consumption rate Ec at the time of turning on the headlight (that is, including the power consumption of the headlight), the energy consumption rate at the time of turning off the headlight after sunrise is expressed.
Note that the cruising range D when the cruising is impossible after sunrise (within H2 hours), that is, when Er−Ec × H2 ≦ 0, is calculated based on the formula (2) shown in the first embodiment. The

A configuration is shown in which a warning is given to the user by changing the display of the reachable range displayed on the display unit 8 when the parking area becomes unreachable. The map display device 10 according to the fourth embodiment is the same as the configuration described in the first embodiment with reference to FIGS. 1 and 2 and the second embodiment with reference to FIG. 7 or FIG. In the following description, the same reference numerals as those used in the first and second embodiments are used.

The operation of the map display device according to the fourth embodiment will be described with reference to the flowchart of FIG. In the flowchart of FIG. 15, steps that perform the same processing as the processing shown in FIG. 6 of the first embodiment are denoted by the same reference numerals as those used in FIG. 6, and description thereof is omitted or simplified.
When the cruising range calculation unit 22 calculates the cruising range D in step ST5, the cruising range calculation unit 24 acquires the vehicle position information input from the vehicle position calculation unit 11 and the map data storage unit 3. On the basis of the map data, a point r that is a cruising distance D along the exclusive road for the vehicle is calculated (step ST41). Further, the cruising point calculation unit 24 calculates a parking / stopping point R closest to the point r, which is located between the vehicle position and the point r (step ST42), and calculates from the vehicle position to the parking / stopping point R. The cruising range A is calculated (step ST43). The calculated cruising range A is output to the output control unit 14 together with the map data.

  The output control unit 14 refers to the map data and determines whether or not there is an energy supply facility on the route to the parking and stopping point R within the cruising range A (step T44). If it is determined in step ST44 that there is an energy supply facility on the route to the parking and stopping point R, the cruising range A together with the energy supply facility display mark is displayed as a map (step ST45). On the other hand, when it is determined in step ST44 that there is no energy supply facility on the route to the parking and stopping point R, the cruising range A is displayed on the map and the display of the cruising range A is changed. A warning is displayed to the effect that the energy supply facility cannot be reached (step ST46). Thereafter, the flowchart returns to the process of step ST1 and repeats the above-described process.

FIG. 16 shows a display example of a warning based on the cruising range A corresponding to the set level of the power consuming device and the presence or absence of the energy supply facility. In FIG. 16 and the following description, an example will be described in which it is determined whether there is a charging facility up to the parking and stopping point R while the electric vehicle is traveling on a highway that is a motorway. FIG. 16 shows a map display screen of the display unit 8 when the setting level of the power consuming device is changed in three stages.
FIG. 16A shows a display example when the setting level of the power consuming device is set to “1” by the dial 4 a or the button 4 b which is the user input unit 4. In the case of the setting level “1”, the parking and stopping point R calculated by the cruising point calculation unit 24 is a service area (hereinafter referred to as “SA”) 1, and charging facilities are SA1 and SA1 on the route to this SA1. It exists in two locations of SA2. Therefore, the display unit 8 displays the cruising range A1 from the vehicle position O to SA1 and the charging facility display marks in SA1 and SA2. In this case, a warning for changing the display of the cruising range A1 is not performed because the charging facility exists up to the parking and stopping point R.

  FIG. 16B shows a display example when the setting level of the power consuming device is set to “2” by the dial 4a or the button 4b. In the case of the setting level “2”, the parking and stopping possible point R calculated by the cruising possible point calculation unit 24 is SA2, and the charging facility exists in one location of SA2 on the route to SA2. Therefore, the display unit 8 displays the cruising range A2 from the vehicle position O to SA2 and the display mark of the charging facility in SA2. In this case, a warning for changing the display color of the cruising range A2 is not performed because the charging facility exists up to the parking and stopping point R.

  FIG. 16C shows a display example when the setting level of the power consuming device is set to “3” by the dial 4a or the button 4b. In the case of the setting level “3”, the parking / parking possible point R calculated by the cruising point calculation unit 24 is SA3, and there is no charging facility on the route to this SA3. Therefore, the display unit 8 displays the cruising range A3 from the own vehicle position O to SA3, and changes the display color of the cruising range A3 to, for example, red, or blinks the area to reach the charging facility. Warn that it is possible. Thereby, the user can recognize that the charging facility is unreachable when the power consumption device is used at the setting level 3 and traveling is continued.

  Further, as shown in FIG. 17, the cruising range A1 may be three-dimensionally displayed in a cylindrical shape. Although not shown, the cruising range A may be displayed in a conical shape with the own vehicle position O as a vertex. The conical shape protrudes most at the own vehicle position O, and the height of the conical shape decreases as the distance from the own vehicle position O increases. That is, the protruding height at a certain point corresponds to the remaining energy of the host vehicle. That is, the user can recognize the decrease in the remaining energy due to traveling from this conical shape. Further, as a different configuration, an area other than the cruising range A may be displayed translucently.

  As described above, according to the fourth embodiment, a point r that is a cruising distance D away from the own vehicle position along the exclusive road is calculated, and a point r located between the own vehicle position and the point r is calculated. Cruising range calculation unit 22 that calculates parking / stopping point R closest to the vehicle, and output control for changing the display of cruising range A based on whether there is an energy supply facility on the route to parking / stopping point R Since it comprised so that the part 14 might be provided, the user can judge easily whether it can continue to an energy supply installation by the setting of the present electric power consumption apparatus.

  In the fourth embodiment described above, the case where the vehicle is traveling on a motorway has been described as an example, but the present invention may be applied to traveling on a general road.

  Further, the configuration of the fourth embodiment described above may be provided in addition to the map display device 10 shown in the third embodiment.

Embodiment 5. FIG.
In the fifth embodiment, a route that travels on a daily basis is stored as a tour route, and a route that can be traveled and a route that cannot be traveled are separated from the cruising range D calculated by the cruising range calculation unit 22. Indicates the configuration to be displayed. For example, a visiting care vehicle travels a plurality of predetermined routes every day and returns to the departure point. Assuming such use, return to the starting point based on the remaining energy, temperature (air conditioner setting), weather (wiper setting), time (headlight setting), etc. of the stored tour route A configuration for displaying a warning for a tour route that cannot be performed will be described.

  18 and 19 are block diagrams showing the configuration of the map display device according to the fifth embodiment. The map display device 10 according to the fifth embodiment has the configuration described with reference to FIG. 1 to FIG. 3 in the first embodiment, and further stores a traveling route memory in which the route that the control unit 1 travels on a daily basis is stored. A portion 16 is provided. In the following description, the same or corresponding parts as those of the map display device 10 according to the first embodiment are denoted by the same reference numerals as those used in the first embodiment, and the description thereof is omitted or simplified.

  The traveling route storage unit 16 stores in advance the traveling route input via the user input unit 4 and the distance of the traveling route. When a mode for determining traveling on a traveling route is selected via the user input unit 4, the stored traveling route and its distance are output to the output control unit 14. Further, the cruising range calculation unit 13 estimates the power consumption device to be used based on the temperature, weather, current time, or the like that is input via the user input unit 4 or acquired via the network via the communication unit 9. To do. The cruising range calculation unit 13 has a driving energy consumption rate of the power consuming device in advance as a database, and energy per unit time required to drive the power consuming device estimated to be used with reference to the database. A consumption amount (hereinafter referred to as an estimated driving energy consumption rate) is calculated.

  The cruising range calculation unit 22 includes the remaining energy Er obtained from the remaining energy acquisition unit 5, the estimated driving energy consumption rate of the power consuming device estimated by the cruising range calculation unit 13, and the consumed energy. The cruising range D is calculated from the kinetic energy consumption rate related to the travel of the host vehicle acquired from the rate acquisition unit 6. The calculated cruising distance D is output to the output control unit 14 via the cruising area calculation unit 23.

  The output control unit 14 compares the traveling route distance input from the traveling route storage unit 16 with the cruising distance D, and determines whether traveling on the traveling route is possible. When the distance of the tour route is equal to or shorter than the cruising distance D, it is determined that the route can be returned to the departure point, and the display of the tour route is displayed in the same manner as a normal route. On the contrary, when the distance of the tour route is longer than the cruising distance D, it is determined that the route cannot be returned to the departure point, and display control for displaying the tour route with a warning (displayed with a dotted line or red) is performed.

  FIG. 20 is a diagram illustrating a display example of a tour route of the map display device according to the fifth embodiment. For example, when the remaining energy of the host vehicle is 100%, three tour routes 1, 2, and 3 that can be navigated are stored in the tour route storage unit 16, and the current remaining energy of the host vehicle is 70%. In this case, it is shown that it is determined that it is impossible to return to the departure point on the longest traveling route 3. The traveling route 3 is displayed with a dotted line, and the user is warned that the traveling route 3 cannot return to the departure point.

Next, an operation for determining whether or not the traveling route can be performed will be described with reference to the flowchart of FIG.
When the mode for judging the traveling of the traveling route is selected via the user input unit 4 (step ST51), the cruising range calculation unit 13 calculates the current position of the host vehicle calculated from the host vehicle position information, and the current position at the current position. An estimated driving energy consumption rate of the power consuming device estimated to be used from the external condition is acquired (step ST52).

  The cruising range calculation unit 22 receives the remaining energy Er acquired from the remaining energy acquisition unit 5, the estimated driving energy consumption rate of the power consuming device estimated to be used acquired in step ST52, and the consumed energy rate acquisition unit 6. The cruising range D is estimated from the travel energy consumption rate related to the travel of the host vehicle to be acquired (step ST53), and is output to the output control unit 14 via the cruising range calculation unit 23. The output control unit 14 acquires the traveling route and the distance of the traveling route from the traveling route storage unit 16 (step ST54), and determines whether the distance of the traveling route is longer than the cruising distance D (step ST55). .

  In step ST55, when it is determined that the distance of the tour route is longer than the cruising distance D, display control for displaying a warning of the tour route is performed (step ST56). On the other hand, when it is determined in step ST56 that the distance of the cyclic route is equal to or shorter than the cruising distance D, control is performed to display the cyclic route in the same manner as a normal route (step ST57). Thereafter, the output control unit 14 determines whether or not display control has been performed for all the cyclic routes (step ST58), and when the determination is made for all of the circular routes, the processing ends. On the other hand, if the determination is not made for all the traveling routes, the process returns to step ST55 and the above-described processing is repeated.

  As described above, according to the fifth embodiment, the traveling route is stored when the traveling route storage unit 16 that stores the traveling route in advance and when the traveling route distance is longer than the estimated traveling distance D are estimated. Since it is configured to include the output control unit 14 that performs a warning display indicating that it is impossible, the presentable remaining energy and the path that can be visited according to the power consuming device that is estimated to be used are presented to the user Can do. Thus, the user can easily select a route that can be reliably visited.

  Further, according to the fifth embodiment, whether or not the traveling route can be traveled based on the estimated driving energy consumption rate of the power consuming device that is estimated to be used based on external conditions such as temperature, weather, and time. Therefore, it is possible to make a more accurate traveling determination in accordance with external conditions during traveling.

  In addition, in Embodiment 5 mentioned above, although the database which showed the drive energy consumption rate of an electric power consumption apparatus was shown in the cruising range calculation part 13, the cruising range calculation part 22 showed the said database. It is good also as a structure to have.

  The above configuration may be applied to the map display device 10 shown in the second embodiment.

Embodiment 6 FIG.
In the sixth embodiment, various configurations of the output control unit 14 will be described.
First, FIG. 22 shows an example in which the display speed of the cruising range A is changed following the operation speed of the user input unit 4. When the setting level of the power consuming device is changed from 1 to 3 via the user input unit 4, the cruising range A is changed in accordance with the operation of the user input unit 4 (for example, turning a dial or pressing a button). Adjust the speed.

  This will be specifically described with reference to FIGS. 22 (a) to 22 (c). When the user input unit 4 is a dial 4a as shown in FIG. 22A and the setting level is changed from 1 to 3 by turning the dial 4a, the rotation speed of the dial 4a is shown in FIG. 22B. To change. Near the setting level 1 (time T0), the moving speed is 0, the speed is increased toward the setting level 2 and the dial 4a rotates, and the moving speed decreases near the setting level 2 (time T1). At 2 (time T1 to T2), the moving speed becomes 0 and the rotation of the dial 4a stops. Similarly, the dial 4a rotates at an increased speed toward the setting level 3, and the moving speed decreases near the setting level 3 (time T3). When the setting level 3 is reached, the moving speed becomes 0 and the rotation of the dial 4a stops. To do.

  The display speed of the cruising range A is also changed in the same manner as the speed change in FIG. When changing from the cruising range A1 corresponding to the setting level 1 of the user input unit 4 to the cruising range A3 corresponding to the setting level 3 as shown in FIG. 22C, the time from the time T0 of the cruising range A1 The speed is increased to T1 to decrease the region, and the decrease in the cruising range stops from time T1 to time T2, which is the outermost periphery of the cruising range A2. Thereafter, the speed is increased again from the time T2 in the cruising range A2 to the time T3 to decrease the region, and when the time T3 that is the outermost periphery of the cruising range A3 is reached, the change stops.

  Thus, the visibility of the map display is improved by performing the display control that follows the operation feeling of the user input unit 4. In addition to the above configuration, a configuration may be provided in which the change in the cruising range A is temporarily stopped even at a dominant point on the map display such as the destination of the host vehicle. As a result, the user can more easily recognize the dominant point in the map display.

Further, as a different display control method, a configuration in which the setting of the power consuming device is displayed in correspondence with the presence or absence of the energy supply facility is shown. In the following description, an air conditioner will be described as an example of a power consuming device. However, the present invention can also be applied to the setting of a power consuming device that does not affect the traveling of the vehicle such as audio.
When an air conditioner is selected as a power consuming device via the user input unit 4 (see FIG. 23 (a)), as shown in FIG. The cruising range A corresponding to the temperature is displayed. In the example of FIG. 23B, when the set temperature is set from 27 degrees to 29 degrees, the charging facility is at least within the cruising range A (27 degrees), A (28 degrees), and A (29 degrees). Since there is one place, the cruising range A (27 degrees), A (28 degrees) and A (29 degrees) are displayed in blue, for example. On the other hand, when the set temperature is set to 26 degrees, it is impossible to reach the first charging facility located at SA3. Therefore, the cruising range A (26 degrees) of the set temperature 26 is set to, for example, a red indicating a warning. In addition, the message “Recommended temperature 27 ° C or higher is recommended” is displayed as a message to the user, and it is proposed that the temperature setting of the air conditioner be 27 ° C or higher. Thereby, the user confirms the displayed cruising range A, warning display or display message, and determines the set temperature of the air conditioner.

A processing operation for displaying the setting of the air conditioner in correspondence with the presence or absence of the energy supply facility will be described with reference to the flowcharts of FIGS.
When the cruising range calculation unit 13 detects an input of a setting button (not shown) of the air conditioner (step ST61), the driving energy consumption rate at each preset temperature of the air conditioner held in advance is output to the cruising range calculation unit 22. (Step ST62). The cruising range calculation unit 22 calculates the driving energy consumption rate at each set temperature of the air conditioner input in step ST62, the remaining energy Er acquired from the remaining energy acquisition unit 5, and the own energy acquired from the consumed energy rate acquisition unit 6. Based on the kinetic energy consumption rate related to the traveling of the vehicle, the cruising distance D at each set temperature of the air conditioner is calculated (step ST63). The cruising area calculation unit 23 calculates a cruising range A based on the cruising distance D calculated in step ST63 (step ST64). The calculated cruising range A is output to the output control unit 14 together with the map data.

  The output control unit 14 refers to the map data to extract the energy supply facility (step ST65), and determines whether there is an energy supply facility that can be reached in the cruising range A corresponding to each set temperature of the air conditioner. Is performed (step ST66). If it is determined in step ST66 that the energy supply facility exists within the cruising range A corresponding to the set temperature of the air conditioner, the cruising range A is displayed together with the display mark of the energy supply facility (step ST67). On the other hand, when it is determined in step ST66 that there is no energy supply facility in the cruising range A corresponding to the set temperature of the air conditioner, the cruising range A is displayed as a warning (step ST68).

  Thereafter, the output control unit 14 determines whether or not the process of step ST66 has been performed for all the air conditioner set temperatures (step ST69). When it is determined in step ST69 that the processing has been performed for all the air conditioner set temperatures, a recommended air conditioner set temperature is calculated with reference to the process result in step ST66, and the recommended set temperature is displayed as a message. Control is performed (step ST70). On the other hand, when it is determined in step ST69 that the process has been performed for all the air conditioner set temperatures, the process returns to step ST66 and the above-described process is repeated.

  Here, since the power consumption of the air conditioner is determined according to the set temperature of the air conditioner, it is assumed that the cruising range calculation unit 13 previously has a drive energy consumption rate corresponding to each set temperature as a database. The cruising range calculation unit 22 may have the database.

Further, as shown in the flowchart of FIG. 25 as a different configuration, after calculating and displaying the recommended air conditioner set temperature in step ST70, the output control unit 14 is controlled by the vehicle control unit (not shown) via the communication unit 9. The set temperature of the air conditioner is acquired, and it is determined whether or not it is possible to reach the nearest energy supply facility from the current position at the set temperature (step ST71). If it is determined in step ST71 that it cannot be reached, the recommended air conditioner set temperature calculated in step ST70 is output as a control instruction to the vehicle control unit via the communication unit 9 (step ST72). On the other hand, if it is determined in step ST71 that it is reachable, the process is terminated without controlling the air conditioner.
The vehicle control unit to which the control instruction is input in step ST72 sets the set temperature of the air conditioner to a recommended temperature. Thereby, the air conditioner can be automatically controlled to a recommended temperature.

  In this way, a warning is displayed for the set temperature at which the energy supply facility closest to the current position cannot be reached, and the recommended air conditioner set temperature can be notified to the user. Furthermore, it becomes possible to automatically control the set temperature of the air conditioner to a temperature that can reach the energy supply facility. Furthermore, the present invention is not limited to the air conditioner, and can be configured to automatically control the setting of the power consuming device that does not affect the traveling of the host vehicle according to the determination result of whether the energy supply facility can be reached. When automatic control is performed, a configuration may be adopted in which the user is notified that automatic control has been performed, such as canceling the warning display.

  As described above, according to the sixth embodiment, the output control unit 14 is configured to perform display control of the cruising range A following the operation feeling of the user input unit 4. The operation and the cruising range A can be displayed in association with each other. Thereby, the user can easily recognize the change in the cruising range A due to the setting of the power consuming device.

  Further, according to the sixth embodiment, the cruising range calculation unit 13 calculates the cruising range A corresponding to each set temperature of the air conditioner, and the output control unit 14 within the cruising range A at each set temperature of the air conditioner. It is determined whether there is an energy supply facility, and if it does not exist, the cruising range A is displayed as a warning and the recommended air conditioner set temperature is notified. The temperature can be easily recognized. Note that even a power consuming device other than an air conditioner can notify a recommended setting, and the same effect can be obtained.

  According to the sixth embodiment, the recommended set temperature of the air conditioner is output as a control instruction to the vehicle control unit via the communication unit 9, and the air conditioner is set to the recommended temperature via the vehicle control unit. Since it comprised as mentioned above, it can control automatically to the preset temperature which the own vehicle can reach | attain energy supply equipment, without bothering a user's hand. Note that even power consumption devices other than air conditioners can be automatically controlled to the recommended settings, and similar effects can be obtained.
