  Next, it is assumed that the user starts driving the car and the car starts running. Then, the current position information acquisition unit 12 starts acquiring current position information. In addition, the non-traveling route information acquisition unit 15 also starts acquiring the non-traveling route information. The remaining fuel amount information acquisition unit 16 also starts acquiring remaining fuel information. Thereafter, each of the current position information acquisition unit 12, the untraveled route information acquisition unit 15, and the remaining fuel amount information acquisition unit 16 continues to acquire predetermined information periodically while the car navigation is powered on.

  Here, it is assumed that the automobile has arrived at point B in FIG.

Then, the travelable position information acquisition unit 1715 ends the acquisition when the calculated sum reaches “50 km”, and acquires the position indicating the end point of the last acquired route as the travelable position information. As a result, it is assumed that the travelable position information acquisition unit 1715 has acquired travelable position information indicating the position of the point B in FIG.

  Next, the fuel replenishment point information acquisition unit 1716 has a fuel replenishment point acquisition condition “10L” acquired by the fuel remaining amount information acquisition unit 16 stored in the fuel replenishment point acquisition condition storage unit 1713. It is determined whether or not “fuel remaining amount ≦ 15 L” is met. Then, the fuel supply point information acquisition unit 1716 determines that the fuel remaining amount information matches the fuel supply point acquisition condition.

  Next, the refueling point information acquisition means 1716 is a refueling point located on the route from point A to point B in FIG.

Then, the control means 272 “+ 2 ° C.” to the set temperature of the air conditioning equipment according to the set temperature related information (increase the set temperature by 2 ° C.).

  Further, for example, similarly to Example 1 of the first embodiment, the set temperature related information acquisition unit 1712 acquires the set temperature related information “20 ° C. + (D + F) / 100” of “ID = 061” in FIG. As a result, it is assumed that the set temperature information “23 ° C.” is calculated. Then, the control means 272 sets the set temperature of the air conditioning equipment to “23 ° C.” according to the set temperature related information.

  Further, for example, assume that the mode of the air conditioning equipment is heating and the set temperature is “28 ° C.”. In this case, the set temperature related information acquisition unit 1712 acquires the mode information “heating” and the current set temperature information “28 ° C.” from the air conditioning equipment. The set temperature related information acquisition unit 1712 then sets the mode information and the current set temperature information to the set temperature acquisition condition “(mode = heating) & (set temperature ≧ 26 ° C.)” of “ID = 063” in FIG. Judge that it matches. Then, the set temperature related information acquisition unit 1712 acquires the set temperature related information “Let's lower the temperature a little more” of “ID = 063” in FIG.

  Next, the control unit 272 slightly lowers the set temperature of the air conditioning equipment according to the set temperature related information “Let's lower the temperature a little more” acquired by the set temperature related information acquisition unit 1712. Specifically, set temperature difference information corresponding to “a little” in the set temperature related information is determined in advance. For example, it is assumed that the set temperature difference information is “2 ° C.”. Further, the control means 272 determines that the set temperature is to be lowered from the “decrease” included in the set temperature related information. And the control means 272 makes "-2 degreeC" from the setting temperature of an air-conditioning equipment from "2 degreeC" and "decrease" (setting temperature is lowered 2 degreeC).

(Remaining amount ≧ 50 L) ”. Then, the motor control content information acquisition unit 2714 acquires the motor control content information “rotation speed ≦ 8000 rpm” of “ID = 011” in FIG. The prime mover control content information is prime mover rotational speed range information indicating a rotational speed range of the prime mover.

  Next, the control means 272 controls the rotational speed of the prime mover so that the rotational speed of the prime mover becomes “8000 rpm or less” in accordance with the prime mover control content information “revolution speed ≦ 8000 rpm” acquired by the prime mover control content information acquisition means 2714. To do. Specifically, for example, while the accelerator depression amount is a depression amount corresponding to the rotational speed “8000 rpm or less” of the prime mover, the control unit 272 transmits the depression amount to the prime mover. Then, while the accelerator depression amount is a depression amount exceeding the rotational speed “8000 rpm” of the prime mover, the control means 272 does not transmit the depression amount to the prime mover, and determines the depression amount corresponding to the rotational speed “8000 rpm”. Send to prime mover.

  Further, for example, as a result of the vehicle continuing to travel, the untraveled route information acquired by the untraveled route information acquiring unit 15 is “45 km”, and the fuel remaining amount information acquired by the fuel remaining amount information acquiring unit 16 is “25L”. ”. In this case, the prime mover control content information acquisition means 2714 indicates that the non-traveling route information and the remaining fuel amount information indicate that the prime mover control content acquisition condition “(distance <50 km) & (remaining amount ≦≦” of “ID = 013” in FIG. 25L) ”. Then, the motor control content information acquisition unit 2714 acquires the motor control content information “rotation speed ≦ 6000 rpm” of “ID = 013” in FIG. 10. Then, the control means 272 controls the rotational speed of the prime mover so that the rotational speed of the prime mover becomes “6000 rpm or less” according to the prime mover control content information.

  In addition, for example, it is assumed that the automobile is stopped by a red signal. At this time, it is assumed that the remaining fuel amount information acquired by the remaining fuel amount information acquiring unit 16 is “8L” and the speed information acquired by the speed information acquiring unit is “0 km / h”. In this case, the motor control content information acquisition unit 2714 indicates that the fuel remaining amount information and the speed information indicate that the motor control content acquisition condition “(residual amount ≦ 10 L) & (speed = 0 km / w)” of “ID = 014” in FIG. h) ”. Then, the motor control content information acquisition unit 2714 acquires the motor control content information “OFF” of “ID = 014” in FIG. 10. The prime mover control content information is prime mover stop information indicating that the prime mover is stopped. And the control means 272 stops a motor | power_engine according to the said motor | power_engine control content information.

  As described above, according to the vehicle-mounted device 2 according to the present embodiment, for example, the control of the set temperature of the air-conditioning equipment or the control of the prime mover according to the untraveled route among the routes to the destination and the remaining amount of fuel. The predetermined control can be performed.

(Embodiment 3)
In the present embodiment, an in-vehicle device 3 that determines a route according to an untraveled route out of the set route to the destination and the current remaining fuel amount will be described. The in-vehicle device 3 in the present embodiment is, for example, a car navigation system, a display / audio, or the like, and is usually mounted on a moving body. In addition, the mobile body is usually one that travels on land and has a prime mover that operates with some energy source. Examples of the energy source include gasoline, light oil, and electric power. The prime mover is, for example, an engine or a motor.

  FIG. 11 is a block diagram of the in-vehicle device 3 in the present embodiment. The in-vehicle device 3 includes a map information storage unit 11, a current position information acquisition unit 12, a reception unit 13, a route search unit 14, an untraveled route information acquisition unit 15, a fuel remaining amount information acquisition unit 16, and a processing unit 37. The processing unit 37 includes a search route management information storage unit 371, a route condition acquisition unit 372, a conditional route search unit 373, and an output unit 374.

  The processing unit 37 performs a predetermined process according to the non-traveling route information acquired by the non-traveling route information acquisition unit 15 and the fuel remaining amount information acquired by the fuel remaining amount information acquisition unit 16. In the present embodiment, the predetermined process is a route search. Specifically, the processing unit 37 acquires a route condition that is a condition related to a route to be searched, and searches for a route that matches the route condition. Note that the processing unit 37 usually acquires a route condition by each means described later, and searches for a route that matches the route condition.

  The searched route management information storage means 371 stores one or more searched route management information. The searched route management information is usually information having a route search start condition and a route condition. The route search start condition is a condition for starting a search for a route corresponding to the non-traveling route information acquired by the non-traveling route information acquisition unit 15 and the fuel remaining amount information acquired by the fuel remaining amount information acquisition unit 16. . The route search start condition is usually a condition related to the non-traveling route information or the fuel remaining amount information. The route search start condition is, for example, that the reception unit 13 has received destination information, or that the reception unit 13 has received a route search instruction having destination information. For example, a predetermined time has passed (periodically). Note that the format and content of the route search start condition are the same as the format and content of the set temperature acquisition condition, the fuel supply point acquisition condition, and the like, and thus description thereof is omitted.

  The route condition is a condition related to a route to be searched. The route conditions include, for example, a refueling point condition that is a condition related to a fuel supply point on the route, a traffic signal condition that is a condition related to a traffic signal on the route, a distance condition that is a condition related to a route distance, and a condition related to a road in the route The road condition is. The refueling point condition is, for example, that there is a refueling point on the route, or that there is a refueling point on a route within a predetermined distance from the current position. Further, the traffic signal condition is, for example, that the number of traffic signals on the route is the minimum, or the number of traffic signals on the route is a predetermined number or less. The distance condition is that the distance of the route is the shortest, the distance of the route is a predetermined distance or less, and the like. The distance is usually a spatial distance, but may be a temporal distance. The road conditions include, for example, that the road in the route is a toll road (for example, an expressway), that the road in the route is not a toll road, and that the road structure in the route is a tunnel. Further, the route condition may be a combination of two or more of these conditions.

  Further, the route search start condition may include, for example, an untraveled route condition that is a condition related to an untraveled route indicated by the untraveled route information. Non-traveling route conditions are, for example, the above-described refueling point conditions, traffic signal conditions, route conditions, road conditions, and the like.

  The route condition acquisition unit 372 selects a route condition corresponding to a route search start condition that matches the non-travel route information acquired by the non-travel route information acquisition unit 15 and the fuel remaining amount information acquired by the fuel remaining amount information acquisition unit 16. Obtained from the searched route management information storage means 371. Note that the method and procedure for acquiring the route condition by the route condition acquiring unit 372 are the same as the method and procedure for acquiring the set temperature related information by the set temperature related information acquiring unit 1712 and will not be described.

  The conditional route search means 373 is a route from the current position to the destination according to the non-traveling route information acquired by the non-traveling route information acquisition unit 15 and the fuel remaining amount information acquired by the fuel remaining amount information acquisition unit 16. Explore. When the route condition acquisition unit 372 acquires the route condition, the conditional route search unit 373 searches for a route that is a route from the current position to the destination and indicates a route that matches the route condition. Acquire conditional route information indicating a route.

  The conditional route search means 373 applies, for example, the current position information acquired by the current position information acquisition unit 12 and the destination information included in the route search instruction received by the reception unit 13 to the map information. A route from the current position indicated by the position information to the destination indicated by the destination information is searched for a route that matches the route condition, and the route information indicating the route is acquired as conditional route information. In addition, the route to be searched is usually a route different from the route indicated by the route information acquired by the route search unit 14.

  For example, when the route condition acquired by the route condition acquisition unit 372 is “the number of traffic signals is minimum”, the conditional route search unit 373 searches for two or more routes from the current position to the destination. Then, the route having the smallest number of signals is selected from the routes. For example, when the route condition acquired by the route condition acquisition unit 372 is “the distance of the route is the shortest”, the conditional route search unit 373 selects two or more routes from the current position to the destination. Search and select the route having the shortest distance among the routes. For example, when the route condition acquired by the route condition acquisition unit 372 is “there is a fuel supply point”, the conditional route search unit 373 searches for two or more routes from the current position to the destination. The route with the fuel supply point is selected from the routes.

  In general, in route search, a route from a departure point to a destination is searched in consideration of the cost (time, distance, fuel consumption, fee, etc.) of a road between points (nodes) on the map. Therefore, the conditional route search unit 373 may perform route search by changing the cost according to the route condition acquired by the route condition acquisition unit 372.

  For example, when the route condition acquired by the route condition acquisition unit 372 is “the number of traffic signals is minimum”, the conditional route search unit 373 has, for example, two or more road options at one point. When the number of traffic signals on the two or more roads is compared, the cost is reduced such that the smaller the number of traffic signals, the greater the reduction in road costs. For example, when the route condition acquired by the route condition acquisition unit 372 is “the distance of the route is the shortest”, the conditional route search unit 373 has, for example, two or more road options at one point. In some cases, the distances of the two or more roads are compared, and the cost is reduced so that the decrease in the road cost increases as the distance decreases. For example, when the route condition acquired by the route condition acquisition unit 372 is “there is a fuel supply point”, the conditional route search unit 373 has, for example, two or more road options at one point. Of the two or more roads, the cost is reduced so that the cost of the road where the refueling point is located is smaller than the cost of the other roads.

  The conditional route search unit 373 only needs to be able to search for a route that matches the route condition acquired by the route condition acquisition unit 372, and any method or procedure for searching for the route may be used.

  The output unit 374 outputs the conditional route information acquired by the conditional route search unit 373. At this time, the output unit 374 normally outputs conditional route information in association with the map information stored in the map information storage unit 11. “Output in association with map information” means that the point or destination through which the route indicated by the conditional route information passes corresponds to the point on the map indicated by the map information. To output.

  Note that the processing unit 37, the route condition acquisition unit 372, and the conditional route search unit 373 can be usually realized by an MPU, a memory, or the like. The processing procedure of the processing unit 37 and the like is usually realized by software, and the software is recorded on a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  The search path management information storage unit 371 is preferably a non-volatile recording medium, but can also be realized by a volatile recording medium. In addition, the process of storing predetermined information in the search route management information storage unit 371 is not limited. For example, information may be stored in the search route management information storage unit 371 via a recording medium. Information transmitted via a communication line or the like may be stored in the search route management information storage unit 371. Further, information input via the input device may be stored in the search route management information storage unit 371.

  In addition, the output unit 374 may be considered to include an output device such as a display or a speaker, or may not be included. The output means 374 may be realized by output device driver software, or output device driver software and an output device.

  Next, the overall operation of the in-vehicle device 3 will be described using the flowchart of FIG. Note that the i-th information in the predetermined information is described as “information [i]”.

If they match, the process proceeds to step S1303, and if not, the process proceeds to step S1305.

  (Step S1303) The route condition acquisition unit 372 acquires the route condition [i] stored in the searched route management information storage unit 371.

  (Step S1304) The path condition acquisition unit 372 determines whether i is m. If m, the process returns to the upper process, and if not, the process proceeds to step S1306.

  (Step S1305) The path condition acquisition unit 372 increments i by 1, and returns to Step S1302.

  (Step S1306) The conditional route search means 373 selects two or more routes from the current position indicated by the current position information acquired in Step S1206 to the destination indicated by the destination information included in the route search instruction received in Step S1201.

Further, the in-vehicle device 3 is assumed to be a car navigation system (hereinafter referred to as “car navigation”) mounted on a car. Further, it is assumed that the search route management information storage unit 371 stores the search route management information shown in FIG. The searched route management information includes an ID (item name: ID) for uniquely identifying a record, a route search start condition (item name: start condition), and a route condition (item name: route condition). In addition, regarding the acquisition of the non-traveling route information by the non-traveling route information acquisition unit 15 and the acquisition of the fuel remaining amount information by the fuel remaining amount information acquisition unit 16, the specific example of the first embodiment and the specific example of the second embodiment Since it demonstrated in the example, description is abbreviate | omitted.

  First, as in Example 1 of the first embodiment, as a result of the user performing an operation on the car navigation system, the non-traveling route information acquisition unit 15 acquires the non-driving route information “220 km” and the remaining fuel amount information acquisition unit It is assumed that 16 has acquired the remaining fuel amount information “18L”.

  Next, the route condition acquisition means 372 indicates that the untraveled route information “220 km” and the remaining fuel amount information “18L” are the route search start condition “(distance ≧ 200 km) & (remaining amount)” of “ID = 011” in FIG. ≦ 20L) ”. Then, the route condition acquisition unit 372 acquires the route condition “refueling point = present” of “ID = 011” in FIG. The route condition means that there is a refueling point on the route.

  Next, the conditional route search means 373 searches for two or more routes from the current position indicated by the current position information acquired by the current position information acquisition unit 12 to the destination indicated by the destination information received by the reception unit 13. To do. And the conditional route search means 373 acquires the conditional route information which shows the route which has a fuel supply point on a route among the searched routes. Then, the output unit 374 outputs the conditional route information. The state of output at this time is, for example, as shown in FIG. In FIG. 15, the moving body is traveling from the point X to the point Y. At the point B, the conditional route search unit 373 acquires the conditional route information, and the output unit 374 outputs the conditional route information. It is a state when I did it. A dotted line between the point B and the point Y is a route indicated by the route information acquired by the route search unit 14, and a solid line between the point B and the point Y is a conditional route acquired by the conditional route search means 373. This is the route indicated by the route information.

  At this time, the conditional route search means 373 usually acquires one conditional route information. In addition, when two or more conditional route information that matches the route condition is acquired, the conditional route search unit 373 normally acquires one conditional route information from the two or more conditional route information. The conditional route search unit 373 holds, for example, the same condition as the route condition stored in the searched route management information storage unit 371 (hereinafter, “route selection condition”), and acquired two or more pieces of conditional route information. Among them, one conditional route information that matches the route selection condition is acquired. Note that the format and contents of the route selection condition are usually the same as the format and content of the route condition.

  In addition, the conditional route search means 373 may perform route search, for example, using the reciprocal of the number of fuel supply points on the road between points on the map as the cost of the road. In this case, the cost increases as the number of fuel supply points decreases, and the cost decreases as the number of fuel supply points increases. Therefore, a route having a large number of fuel supply points can be searched.

  Further, for example, as a result of the user operating the car navigation system, the non-traveling route information acquisition unit 15 acquires the non-traveling route information “80 km”, and the fuel remaining amount information acquisition unit 16 acquires the fuel remaining amount information “35L”. ”.

  Next, the route condition acquisition means 372 indicates that the non-traveling route information “80 km” and the remaining fuel amount information “35L” indicate that the route search start condition “(distance ≧ 50 km) & (remaining amount)” of “ID = 013” in FIG. ≦ 40L) ”. Then, the route condition acquisition unit 372 acquires the route condition “distance = shortest” of “ID = 013” in FIG. The route condition means that the route distance is the shortest.

  Next, the conditional route search means 373 searches for two or more routes from the current position indicated by the current position information acquired by the current position information acquisition unit 12 to the destination indicated by the destination information received by the reception unit 13. To do. Then, the conditional route search unit 373 acquires conditional route information indicating the route having the shortest distance among the searched routes. Then, the output unit 374 outputs the conditional route information.

  At this time, for example, the conditional route search means 373 may perform a route search using the distance of the road between points on the map as the cost of the road. In this case, the longer the distance, the higher the cost, and the shorter the distance, the lower the cost. Therefore, the route with the shortest distance can be searched.

  Further, for example, as a result of the user operating the car navigation system, the non-traveling route information acquisition unit 15 acquires the non-driving route information “40 km”, and the fuel remaining amount information acquisition unit 16 determines the fuel remaining amount information “5L”. ”.

  Next, the route condition acquisition means 372 indicates that the untraveled route information “40 km” and the remaining fuel amount information “5L” are included in any route search start condition from “ID = 011” to “ID = 013” in FIG. Judge that it does not match. Then, it is assumed that the route condition acquisition unit 372 has acquired the route search start condition “f (distance, remaining amount) ≧ 10 km” of “ID = 014” in FIG. In the route search start condition, “f (distance, remaining amount)” is determined by using the non-traveling route information indicating the distance of the non-traveling route and the remaining fuel amount information, It is a function which calculates the difference (henceforth a driving impossible distance). That is, the route search start condition means that the untravelable distance is “10 km or less”.

  Next, the route condition acquisition unit 372 substitutes the non-traveling route information “40 km” and the remaining fuel amount information “5L” into the function “f (distance, remaining amount)” to indicate the untravelable distance indicating the untravelable distance. It is assumed that information “15 km” has been acquired. Then, the route condition acquisition unit 372 determines that the untraveled route information “40 km” and the remaining fuel amount information “5L” match the route search start condition of “ID = 014” in FIG. Then, the route condition acquisition unit 372 acquires the route condition “fuel supply point position ≦ 5 km” of “ID = 014” in FIG. The route condition means that there is a fuel supply point on a route “within 5 km” from the current position.

  Next, the conditional route search means 373 searches for two or more routes from the current position indicated by the current position information acquired by the current position information acquisition unit 12 to the destination indicated by the destination information received by the reception unit 13. To do. Then, the conditional route search means 373 acquires conditional route information indicating a route having a fuel supply point “within 5 km” from the current position among the searched routes. Then, the output unit 374 outputs the conditional route information.

  As mentioned above, according to the vehicle-mounted apparatus 3 by this Embodiment, a path | route can be determined according to the untraveled path | route of the path | routes to the destination, and the fuel remaining amount.
