  Hereinafter, the energy information providing unit 1 according to the present embodiment will be described based on the drawings. The energy information providing unit 1 according to the present embodiment provides information on the driving energy source of the vehicle including gasoline and other fuels to the vehicle occupant. As a driving energy source of the vehicle, liquefied natural gas, biofuel, hydrogen, alcohol fuel such as methanol, or electricity can be used. In the present embodiment, an energy information providing unit 1 that provides information on fuel such as gasoline among driving energy sources of a vehicle to an occupant of the vehicle will be described as an example.

  FIG. 1 shows a block configuration diagram of an energy information providing unit 1 according to the present embodiment. The energy information providing unit 1 according to the present embodiment includes a fuel information providing apparatus 100 mounted on a vehicle, and a center 2000 capable of exchanging information with the fuel information providing apparatus 100.

  First, the center 2000 will be described. The center 2000 includes a communication device 2300 that communicates with the fuel information providing device 100 mounted on the vehicle, an arithmetic device 2100 that executes processing for calculating the unit price of the driving energy source, unit price information that will be described later, and other necessary information. A storage device 2200 for storing.

  The communication device 2300 of the center 2000 acquires the position information of the vehicle from the fuel information providing device 100 on the vehicle side. Further, the communication device 2300 exchanges information with an external terminal 3000 such as a mobile phone or a computer.

  The storage device 2200 of the center 2000 is based on the position information acquired from the fuel information providing device 100 on the vehicle side, and includes alcohol fuel such as gasoline, liquefied natural gas, biofuel, hydrogen, methanol, or other driving energy source. Unit price information 2210 in which the supply location and the unit price of each drive energy source are associated in advance is stored.

  Unit price information 2210 of the storage device 2200 is a database formed by acquiring a unit price of a driving energy source from a general user. Generation and browsing of the unit price information 2210 is developed as an open WEB service that general users can freely browse and register.

The storage device 2200 of the present embodiment acquires information related to the unit price of each driving energy source from an external terminal 3000 such as a mobile phone or a computer, and accumulates the information in the unit price information 2210. The storage device 2200 includes information for specifying a fueling facility (name of a driving service supply service store), a region including the fueling facility, a fuel type, a fuel brand (a brand of driving energy source), a unit price or a price range of a unit price, purchase Accept postings such as date and time, payment method. The storage device 2200 registers a plurality of pieces of input information including the unit price in the unit price information 2210 among these. The storage device 2200 searches the unit price information 2210 using these items of input information as keys. In addition, the storage device 2200 totals the unit prices of the driving energy sources for each region and for each road, and includes a representative value such as an average value in the unit price information 2210 as a unit price of the region.

Specifically, a user who uses a supply facility for a driving energy source such as a gas station can obtain the unit price of the supply facility (price per unit amount of energy) and information identifying the supply facility from an external terminal such as a mobile phone. Report (post) to the center 2000 via 3000. The center 2000 refers to information that associates the supply facility of the driving energy source with the position information of the supply facility in advance, and obtains the sales unit price (price per unit energy amount) acquired from the user and the position information of the supply facility. Are stored in the storage device 2200 as unit price information 2210.

  For example, the center 2000 operates a CGM (Consumer Generated Media) in which a user (consumer) forms its contents using a communication network such as the Internet, and manages a database such as unit price information 2210. Since this type of database is formed by information transmitted from an individual, the information that is more valuable to the user can maintain the freshness and accuracy of the information. That is, the latest price is more easily reflected in the supply facility with more users, and the unit price information 2210 of the center 2000 can be used as a reliable database.

The arithmetic device 2100 calculates a unit price of the driving energy source and executes a program stored in the ROM (Read Only Memory) 2112 in which a program for executing processing to be sent to the vehicle side is stored. Thus, a CPU (Central Processing Unit) 2111 as an operation circuit that causes the apparatus to function as the center 2000 and a RAM (Random Access Memory) 2113 that functions as an accessible storage device are provided.

  FIG. 2 is a diagram illustrating an example of functional blocks of the fuel information providing apparatus 100 and the center 2000 according to the first embodiment.

As shown in FIG. 2, the arithmetic device 2100 of the center 2000 includes a unit price calculation function 1201 that determines the unit price of the driving energy source of the vehicle, and a center side communication control function 1202 that controls communication with the vehicle side.

  Hereinafter, functions realized by the arithmetic device 2100 of the center 2000 described above will be described.

  First, the unit price calculation function 1201 will be described.

The computing device 2100 refers to the unit price information 2210 stored in the storage device 2200, and based on the position information of the fuel information providing device 100, the alcohol fuel such as gasoline, liquefied natural gas, biofuel, hydrogen, methanol, or the like The supply location of other driving energy sources and the unit price of each driving energy source are obtained. Moreover, the arithmetic unit 2100 calculates a unit price according to the type of driving energy source of the vehicle and a unit price according to the date and time when the vehicle requests unit price information, as necessary.

FIG. 3 is a diagram illustrating an example of unit price information 2210 that is referred to by the arithmetic device 2100 when calculating the unit price. In the unit price information shown in FIG. 3, the unit price information 2210 according to the present embodiment includes identification information (store name) of the supply location of the drive energy source and position information (address, latitude / longitude) of the supply location of the drive energy source. The unit price for each type of drive energy source is associated with the date and time when the unit price information was posted (recorded). The type of driving energy source is, for example, gasoline, liquefied natural gas, biofuel, hydrogen, alcohol fuel such as methanol, or electricity. These driving energy sources may be combined. The type of drive energy source includes a type that subdivides one drive energy source. For example, the types of driving energy sources include types such as regular gasoline, high-octane (high-octane gasoline), and light oil.

The unit price for each type of driving energy source is expressed in yen / liter or dollar / gallon for gasoline, liquefied natural gas, biofuel, alcohol fuel such as methanol or other liquid fuel. In addition, gaseous fuel such as hydrogen is expressed in a circle / m ³ (cubic meter) or the like. Electricity is expressed in yen / kwh (kilowatt hour) or the like. Further, when the tank itself or the battery itself is exchanged, it is expressed by a circle / 1 tank, a circle / 1 battery, or the like.

In addition, when the driving energy source is electricity, the price of electricity charges may fluctuate depending on the time period during which power is supplied (such as late-night power discount). Thus, when the price varies depending on the time zone, the unit price information for each time zone is included in the unit price information 2210 in advance. Thereby, the unit price according to the time of supply can be calculated | required correctly.

The arithmetic device 2100 refers to such unit price information 2210, and obtains the sales unit price at the drive energy source supply location according to the unit price request information acquired from the vehicle side. The unit price request acquired from the vehicle side includes at least the position information (latitude / longitude) of the vehicle when the drive energy source is supplied. Further, the unit price request acquired from the vehicle side can include the type of drive energy source of the vehicle and the supply timing (fuel supply timing) of the drive energy source.

The arithmetic device 2100 refers to the unit price information 2210, and obtains the unit sales price at the supply location of the drive energy source according to the vehicle position information (latitude / longitude) obtained from the vehicle side when the drive energy source is supplied. .

The unit price calculation method is not particularly limited, and the following method can be used.

The computing device 2100 refers to the unit price information 2210, and determines the unit price associated with the drive energy source supply location closest to the position information of the vehicle when it is determined that the drive energy source is supplied to the vehicle. Calculated as the unit price of the supplied drive energy source. Even if the position information of the vehicle included in the unit price request acquired from the vehicle side and the position information of the gas station (the place where the driving energy source is supplied) included in the unit price information 2210 do not completely match, Price can be substituted.

Since the position where the vehicle is present at the timing when it is determined that the drive energy source has been supplied is the key, the gasoline station (supply location) to which the vehicle has supplied the drive energy source such as gasoline can be estimated, so an accurate unit price must be obtained. Can do. Further, even if the unit price information 2210 does not include information on the gas station where the vehicle actually supplies gasoline, the prices of the nearby gas stations can be obtained. Since prices of driving energy sources such as gasoline tend to vary depending on regions, a reliable unit price can be obtained even if a substitute value is used.

In the unit price information 2210, when the predetermined area including the drive energy source supply location and the representative unit price of the drive energy source in the predetermined area are associated in advance, the control device 10 determines the unit price for each area. The unit price is calculated using the information 2210. Regions can be defined arbitrarily. For example, a predetermined area defined by latitude / longitude or a predetermined area defined along a road can be defined as a unit area of the unit price information 2210.

The computing device 2100 refers to the unit price information 2210 for each region, and determines the unit price associated with the predetermined area to which the vehicle position belongs when it is determined that the drive energy source has been supplied. As the unit price of. Even if the unit price information 2210 does not include information on the gas station where the vehicle has actually supplied gasoline, the price of gasoline or the like in that region can be obtained. Since prices of driving energy sources such as gasoline tend to vary depending on regions, a reliable unit price can be obtained even if a substitute value is used.

  In addition, when the unit price information 2210 includes the type information of the driving energy source, the control device 10 determines the type of driving energy source supplied to the vehicle based on the type information included in the unit price request acquired from the vehicle side. Calculate the unit price of. The unit price of the driving energy source varies depending on the type. In calculating the unit price, the control device 10 of the present embodiment determines the type of driving energy source (alcohol fuel or electricity such as gasoline, liquefied natural gas, biofuel, hydrogen, methanol, etc., or gasoline regular gasoline, high-octane gasoline (high octane gasoline). ), Light oil, etc.), the correct unit price can be calculated.

Further, when the unit price information 2210 includes the time when the unit price is posted (stored), the control device 10 uses the unit price information 2210 for each time period or time period to be included in the unit price request acquired from the vehicle side. A unit price for the drive energy source supplied to the vehicle is calculated based on the supply time. At this time, the control device 10 sets the unit price posted (stored) at the time with the smallest time difference from the supply time included in the unit price request acquired from the vehicle side as the unit price of the drive energy source supplied to the vehicle. In this process, it is preferable that the unit price posted (stored) at a time prior to the supply time be the unit price of the drive energy source supplied to the vehicle. The unit price of the driving energy source is fluid and varies depending on the date and time. Since the control device 10 of the present embodiment calculates the unit price based on the supply date and time of the driving energy source when calculating the unit price, it can calculate the accurate unit price.

The database of unit price information 2210 does not necessarily reflect the latest prices of all gas stations (drive energy source supply locations). For example, information about a newly opened gas station is not reflected in the unit price information 2210. In this embodiment, in order to calculate the unit price of the nearest another gas station or the average unit price of a plurality of gas stations in the vicinity, and to set this as the unit price of the drive energy source supplied to the vehicle, Even if the unit price of the gas station is not posted, a reliable unit price can be obtained.

On the other hand, although the unit price of the gas station itself is stored, it is highly possible that the unit price whose price is not updated over a long period of time is different from the actual price. Also in this case, as described above, the unit price of another nearest gas station or the average unit price of a plurality of nearby gas stations is calculated and used as the unit price of the driving energy source supplied to the vehicle. Therefore, even if the unit price of the gas station has not been updated for a long time, a reliable unit price can be obtained. However, if the difference between the unit price that has not been updated for a long time and the peripheral market unit price is less than the predetermined value, the unit may be set at a constant unit price, so that the unit is associated with that unit. Use the unit price.

  Next, the center side communication control function 1202 will be described.

  The arithmetic device 2100 causes the communication device 2300 to send the calculated unit price of gasoline or other driving energy source to the fuel information providing device 100 on the vehicle side. The fuel information providing apparatus 100 provides information on the driving energy source to the occupant using the acquired unit price of the driving energy source.

  Next, the in-vehicle device 1000 including the fuel information providing device 100 will be described.

  The in-vehicle device 1000 of the present embodiment includes a fuel information providing device 100 that provides information on fuel and other driving energy sources of a vehicle to a vehicle occupant, a vehicle controller 200, a vehicle information detection device 300, an output device 400, A position detection device 510 and a communication device 700 are included.

  The fuel information providing apparatus 100 according to the present embodiment includes a vehicle controller 200, a vehicle information detection apparatus 300, an output apparatus 400, a position detection apparatus 510, a communication apparatus 700, a CAN (Controller Area Network), and the like mounted on the same vehicle. Connected to each other by the in-vehicle LAN and exchanges information with each other.

  Hereinafter, the fuel information providing apparatus 100 mounted on the vehicle will be described. As shown in FIG. 1, the fuel information providing apparatus 100 includes a control device 10 that executes a process of providing information on fuel and other driving energy sources of a vehicle to a vehicle occupant.

  The control device 10 executes the program stored in the ROM 12 (Read Only Memory) 12 in which a program for executing information providing processing related to the drive energy source is stored, and executes the program stored in the ROM 12 as a fuel. A CPU (Central Processing Unit) 11 as an operation circuit that functions as the information providing device 100 and a RAM (Random Access Memory) 13 that functions as an accessible storage device are provided. As an operation circuit, instead of or together with the CPU (Central Processing Unit) 11, an MPU (Micro Processing Unit), a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), etc. Can be used.

  As shown in FIG. 2, the control device 10 of the fuel information providing device 100 of the present embodiment includes a remaining amount monitoring function 1101 for monitoring the remaining amount of fuel stored in the vehicle and other driving energy sources of the vehicle, and driving energy. A supply determination function 1102 for determining that a source is supplied, a position acquisition function 1103 for acquiring position information when a drive energy source is supplied, and a type information acquisition function 1104 for acquiring information related to the type of drive energy source A unit price acquisition function 1105 that performs processing for acquiring the unit price of the supplied drive energy source from the center 2000, a vehicle-side communication control function 1106 that controls communication with the center 2000, and a consumption amount of the drive energy source. A consumption calculation function 1107, a price calculation function 1108 for calculating the price of the consumed drive energy source, And an output control function 1109 for controlling the output of the consideration information.

The control device 10 of the fuel information providing device 100 executes each function by cooperation of software for realizing the above function and the above-described hardware.

  Hereafter, the function which the control apparatus 10 of the fuel information provision apparatus 100 mentioned above implement | achieves is each demonstrated.

  First, the remaining amount monitoring function 1101 will be described.

  The control device 10 monitors a change in the remaining amount of the driving energy source stored in the vehicle. The control device 10 acquires the detection information from the fuel level sensor 301 of the vehicle information detection device 300 at a predetermined cycle, and monitors the change of the acquired detection information.

The level sensor 301 of the present embodiment measures the remaining amount in a fuel tank mounted on a vehicle when liquid fuel such as gasoline, liquefied natural gas, LPG, biodiesel fuel, alcohol fuel or the like is used as a drive energy source. . As the level sensor 301, it is possible to use a general liquid amount sensor (remaining amount sensor) that measures the level of oil, water, or other liquid level. Moreover, you may use the water surface sensor which measures the level of a water surface.

  Next, the supply determination function 1102 will be described.

  The control device 10 determines that a drive energy source has been supplied to the vehicle based on various detection information acquired from the vehicle information detection device 300. Specifically, when the remaining amount of the driving energy source detected by the remaining amount monitoring function 1101 increases, the control device 10 determines that the driving energy source has been supplied to the vehicle.

  Further, the control device 10 determines that a driving energy source has been supplied to the vehicle based on the detection result of the supply sensor 302. The supply sensor 302 has a supply amount measurement function for measuring the supply amount of the drive energy source supplied to the vehicle from the outside.

For example, when using gasoline, liquefied natural gas, LPG, biodiesel fuel, alcohol fuel, or other liquid fuel as a drive energy source, the supply sensor 302 measures the flow rate of the supply path of the drive energy source. The control device 10 determines whether or not the drive energy source is supplied based on the supply amount of the drive energy source measured by the supply sensor 302. Specifically, when the supply amount of the drive energy source measured by the supply sensor 302 is greater than or equal to a predetermined amount, the control device 10 determines that the drive energy source has been supplied.

The supply sensor 302 measures the pressure of the supply path of the drive energy source when using gaseous fuel (high-pressure hydrogen gas or the like) used in a fuel cell vehicle, a hydrogen vehicle, or the like as a drive energy source. When supplying gaseous fuel (such as high-pressure hydrogen gas), the high-pressure tank is filled with gas using a high-pressure compressor provided at a supply station (such as a hydrogen station). The vehicle side always monitors the tank pressure with a pressure sensor to calculate the remaining capacity and ensure safety. By detecting an increase in the pressure in the tank by this pressure sensor, it is determined that the tank is filled (supplied) with gaseous fuel. In order to ensure safety, pressure changes due to temperature changes in the tank are monitored in the same way, so whether the pressure change in the tank is due to filling (supply) or due to external factors such as temperature rise, It is determined that gaseous fuel has been filled (supplied) into the tank.

The supply sensor 302 detects the connection of the power supply connector when using electricity used in an electric vehicle or the like as a drive energy source. When electricity is supplied as a driving energy source, charging from the power supply facility is connected to connectors provided in both the power supply facility and the vehicle. On the vehicle side, a connection sensor, a current sensor and the like are provided for safe connection and secondary battery capacity monitoring. Therefore, when the connection of the connector and the supply of current are detected by the connection sensor and the current sensor, it is determined that electricity is charged (supplied) to the storage battery of the vehicle.

Further, the supply sensor 302 detects the signal from the connection sensor of the tank or the battery when the container itself that stores the drive energy source such as a tank or a battery is replaced as a method of supplying the drive energy source. Source supply can be determined.

Next, a method for determining whether or not a drive energy source has been supplied will be specifically described with reference to FIG.

As described above, the control device 10 monitors the remaining amount of fuel and other driving energy sources detected by the level sensor 301 at a predetermined cycle, and acquires information related to the change. The monitoring timing of the remaining amount of the driving energy source can be defined as appropriate, and is set, for example, every 10 seconds or every 10 m of travel distance. Further, when information on the fuel injection amount can be acquired from the fuel injection amount control sensor 304, the remaining amount may be measured every time the fuel injection amount reaches a predetermined amount (1 cc or the like).

FIG. 4 is a diagram illustrating an example of a change in the remaining amount of fuel. The horizontal axis in FIG. 4 is the passage of time or the remaining fuel detection timing, and the vertical axis is the detected remaining fuel. The black circle plot included in FIG. 4 corresponds to the measured value of the remaining amount of fuel. FIG. 4 is not actual measurement data, but the remaining amount of fuel expressed in a simplified manner for easy understanding.

Reference numerals 31 to 34 shown in FIG. 4 are timings when it is determined that the remaining amount of fuel increases. In the area (timing) indicated by reference numeral 31, a significant increase is seen when the values of the remaining fuel amount before and after the area are compared. The control device 10 determines that such an increase in the remaining amount of fuel is due to refueling (supply of drive energy source). That is, the control device 10 determines that refueling (supply of drive energy source) has been performed in the area (timing) indicated by reference numeral 31. Moreover, since the same change is observed also in the area (timing) shown with the code | symbol 35 of FIG. 4, the control apparatus 10 judges with having supplied oil.

On the other hand, in the area (timing) indicated by reference numeral 32 in FIG. 4, an increase in the remaining amount of fuel is recognized, but the increase amount is very small. This can be predicted to be caused by a temporary change in the fuel liquid level due to an error of the level sensor 301, a tilt of the vehicle attitude, or the like. Such an increase in the remaining amount of fuel should not be determined as refueling (supply of drive energy source). In order not to determine such a temporary change in the fuel level due to an error of the level sensor 301 or a tilt of the vehicle posture, etc., the control device 10 determines the amount of fuel in the determination of refueling. A threshold (for example, 1000 cc or the like) is provided for the increase amount. When the fuel increases beyond the set threshold value, it is determined that the fuel has been supplied, so that it is erroneously determined that the change in the remaining amount of the fuel due to the error of the level sensor 301 or the inclination of the vehicle posture is due to the fuel supply. Can be prevented.

In addition, in the area (timing) indicated by reference numeral 33 in FIG. 4, although an increase exceeding the threshold is detected, a rapid decrease is observed in the subsequent monitoring result. Similarly to the timing indicated by reference numeral 32, it is considered that the apparent remaining fuel amount has temporarily increased due to a factor other than refueling. In order not to erroneously determine that fuel has been supplied based on such a change in the remaining amount of fuel, for example, after detecting an increase in the remaining amount of fuel, the control device 10 continues monitoring for a predetermined time (for example, 1 minute). It is confirmed that there is no sudden decrease in the remaining amount within a predetermined time after the increase.

Further, in the area (timing) indicated by reference numeral 34 in FIG. 4, contrary to the area indicated by reference numeral 33, a rapid increase is detected after a sudden decrease in the remaining amount of fuel is detected. Therefore, since a rapid increase is observed based on the time point when the remaining amount of fuel decreases, there is a possibility that the increase in the remaining amount of fuel is erroneously determined as refueling. In order to avoid this, for example, the control device 10 confirms that there is no rapid decrease in the remaining amount of fuel within a predetermined time before an increase in the remaining amount is detected.

Further, the supply determination function 1102 of the control device 10 is designed to improve the accuracy of determination as to whether or not a drive energy source has been supplied, from starting and stopping the vehicle, speed or acceleration of the vehicle, vehicle inclination, vehicle position. This supplements the determination of whether or not the drive energy source has been supplied based on the vehicle information.

Hereinafter, methods for determining whether or not a driving energy source has been supplied based on changes in the remaining amount of fuel and other driving energy sources and changes in other vehicle information will be listed and described.

As a first method, the control device 10 acquires information on stop and restart of the engine of the vehicle from the engine drive sensor 303 of the vehicle information detection device 300. Then, the control device 10 increases the remaining amount of the driving energy source such as gasoline based on the detection information detected by the level sensor 301, and within a predetermined time before and after the remaining amount of the driving energy source increases. When acquiring information on stopping and restarting, it is determined that a driving energy source is supplied to the vehicle.

Fuel and other driving energy sources are supplied only when the vehicle is stopped. The control device 10 determines the accuracy of the determination by determining that the drive energy source is supplied to the vehicle when the engine of the vehicle is stopped and restarted before and after the timing when the remaining amount of the drive energy source increases. To improve.

Note that the control device 10 may acquire information on engine stop and restart from the fuel injection amount control sensor 304.

As a second method, the control device 10 acquires a change in the position of the vehicle from the position detection device 510. Then, the control device 10 increases the remaining amount of driving energy source such as gasoline based on the detection information detected by the level sensor 301, and within a predetermined time before and after the remaining amount of driving energy source increases. If the amount of change in the position of the vehicle is less than the predetermined value, it is determined that the drive energy source is supplied to the vehicle.

The supply of fuel and other driving energy sources is performed only when the vehicle is stopped, that is, not moving. The control device 10 determines that the driving energy source is supplied to the vehicle when the amount of movement of the vehicle is small (less than a predetermined value) before and after the timing when the remaining amount of the driving energy source increases. Improve the accuracy.

As a third method, the control device 10 acquires the speed or acceleration of the vehicle from the speed / acceleration sensor 305 of the vehicle information detection device 300. And the control apparatus 10 acquires within the predetermined time before and after the remaining amount of driving energy sources, such as gasoline, increases based on the detection information detected by the level sensor 301, and the remaining amount of this driving energy source increases. When the state where the speed or acceleration of the vehicle to be performed is less than the predetermined value continues for a predetermined time or more, it is determined that the drive energy source is supplied to the vehicle.

Fuel and other driving energy sources are supplied only when the vehicle stops, that is, when speed and acceleration are not detected. By determining that the driving energy source is supplied to the vehicle when the vehicle speed or acceleration is small (less than a predetermined value) before and after the timing when the remaining amount of the driving energy source increases, the control device 10 Improve the accuracy of judgment.

Further, as a fourth method, the control device 10 acquires vehicle inclination information from the vehicle inclination sensor 306 of the vehicle information detection device 300. Then, the control device 10 increases the remaining amount of the driving energy source such as gasoline based on the detection information detected by the level sensor 301, and the vehicle acquired when the remaining amount of the driving energy source increases. When the inclination is less than a predetermined value, it is determined that the driving energy source is supplied to the vehicle.

Even when the vehicle is inclined, the liquid level position of liquid fuel such as gasoline changes. For this reason, the remaining amount of the drive energy source may increase depending on the posture of the vehicle. The control device 10 determines that the drive energy source is supplied to the vehicle when the remaining amount of the drive energy source increases and the vehicle is not inclined (the inclination is less than a predetermined value). Improve the accuracy of judgment.

Further, as a fifth method, the control device 10 acquires the opening / closing information of the energy source supply path through which the driving energy source is supplied from the outside from the supply path opening / closing sensor 307 of the vehicle information detection apparatus 300. Then, the control device 10 increases the remaining amount of driving energy source such as gasoline based on the detection information detected by the level sensor 301, and within a predetermined time before and after the remaining amount of driving energy source increases. When the opening / closing information of the energy source supply path is acquired, it is determined that the drive energy source is supplied to the vehicle.

When fuel and other driving energy sources are supplied, the energy source supply path is opened and closed. The control device 10 improves the accuracy of the determination by determining that the drive energy source is supplied to the vehicle when the energy source supply path is opened and closed before and after the timing when the remaining amount of the drive energy source increases. .

Further, as a sixth method, the control device 10 supplies, from the supply route connection sensor 308 of the vehicle information detection device 300, the vehicle-side energy source supply route to which the drive energy source is supplied, and the drive energy source to the vehicle side. Connection information with the energy source supply device to be acquired is acquired. Then, the control device 10 increases the remaining amount of driving energy source such as gasoline based on the detection information detected by the level sensor 301, and within a predetermined time before and after the remaining amount of driving energy source increases. If the connection information between the energy supply path and the external energy source supply device is acquired, it is determined that the drive energy source is supplied to the vehicle.

When fuel and other driving energy sources are supplied, the vehicle energy supply path and an external energy source supply device are connected. When the connection information between the energy supply path of the vehicle and the external energy source supply device is acquired before and after the timing when the remaining amount of the drive energy source increases, the control device 10 determines that the drive energy source is supplied to the vehicle. By determining, the accuracy of the determination is improved.

Next, based on FIG. 5, a method for improving the accuracy of determining whether or not fuel has been supplied (a drive energy source has been supplied) using various types of vehicle information other than the remaining amount of fuel will be described.

5A shows the monitoring result of the remaining amount of fuel shown in FIG. 4, FIG. 5B shows the detection result of engine stop / restart, and FIG. 5C shows the movement of the vehicle per unit time. FIG. 5D is a diagram showing the detection result of the inclination displacement of the posture of the vehicle. In addition, although the detection result of the speed or acceleration of the vehicle is used as the detection result of the movement amount of the vehicle, the change amount of the position may be used.

  The horizontal axis of each figure shown in FIG. 5 is the passage of time, and areas (timing) of reference numerals 41 to 44 shown in FIG. 5 are the same timings as reference numerals 31 to 34 shown in FIG.

The vertical axis in FIG. 5B is ON and OFF indicating the on / off of the engine, and this is a history of engine stop and restart. In FIG. 5 (A), at the timings of reference numerals 41 and 44 at which the remaining amount of fuel increases, the engine stop / restart can be confirmed as shown in FIG. 5 (B). For this reason, the control device 10 determines that there is a high possibility that fuel has been supplied at the timings of reference numerals 41 and 44. On the other hand, in FIG. 5A, the history of engine stop / restart is not detected at the timings of reference numerals 42 and 43 at which the remaining fuel amount increases. For this reason, the control device 10 determines that refueling is not performed at the timings of reference numerals 42 and 43.

The vertical axis in FIG. 5C represents the speed displacement of the vehicle. If a value close to 0 km / h is recorded, it can be predicted that the vehicle is in a stopped state. In FIG. 5A, the vehicle speed is close to 0 and less than a predetermined value at the timings of reference numerals 41 and 44 at which the remaining fuel amount increases. That is, it is highly possible that the vehicle has stopped, and it is determined that refueling has been performed at this timing. On the other hand, the speed of the vehicle is high and the stop is not detected at the timings of reference numerals 42 and 43 in which the remaining amount of fuel increases in FIG. For this reason, the control device 10 determines that refueling is not performed at the timings of reference numerals 42 and 43.

  The vertical axis in FIG. 5C is the inclination angle of the posture of the vehicle (vehicle body). The vehicle inclination sensor 306 can detect the degree of inclination based on the speed and acceleration detected by the speed / acceleration sensor 305. For example, if a gravitational acceleration is detected in a direction directly below the vehicle at a speed of 0 km / h, the vehicle can be determined to be horizontal. In FIG. 5A, at the timings of reference numerals 41 and 44 at which the remaining amount of fuel increases, there is no vehicle tilt angle and the vehicle is in a horizontal posture. That is, it can be determined that the increase in the remaining amount of fuel detected at the timings of reference numerals 41 and 44 is not caused by the attitude of the vehicle. On the other hand, the inclination angle of the vehicle is detected at the timings of reference numerals 42 and 43 at which the remaining amount of fuel increases in FIG. 5A, and the vehicle is not in a horizontal posture. For this reason, the control device 10 can determine that the increase in the detected remaining fuel amount is likely due to the attitude of the vehicle at the timings of reference numerals 42 and 43. That is, the control device 10 determines that refueling has been performed at timings 41 and 44 and determines that refueling has not been performed at timings 42 and 43. This is based on the fact that the fueling facility (driving energy source supply facility) is built horizontally, but if it is not always horizontal, the area around the fueling facility is inclined overall. It is premised that the vehicle is inclined (it is unlikely that only the refueling point is inclined), and the displacement (differential value) of the inclination angle is used instead of the inclination angle of the vehicle itself. As a result, it is possible to prevent an erroneous determination that the increase in the remaining amount when the inclination angle changes abruptly as refueling. In addition, when determining whether or not refueling has been performed using the inclination angle of the vehicle, it is desirable to estimate in advance the detection error of the remaining amount of fuel based on the inclination angle of the vehicle. That is, the change in the liquid level corresponding to the tilt angle is mapped in advance, and when the tilt angle actually exists, a process for canceling this is performed. Thereby, it is possible to eliminate the influence by the inclination of the vehicle. FIG. 5 (D) shows either the left / right inclination (roll direction) or the front / rear inclination (pitch direction) of the vehicle for the sake of easy understanding. Consider tilt.

  In addition to this, as described above, the opening / closing information of the filler opening acquired from the supply path opening / closing sensor 307 that detects the opening / closing of the filler opening (supply path) may be considered. In addition, the connection information of the fuel supply port and the power supply plug acquired from the supply route connection sensor 308 that detects attachment / detachment of the fuel supply port and the fuel supply device (connection of the supply route) may be considered.

  In addition, although the method demonstrated above may be employ | adopted independently, the determination precision of the presence or absence of oil supply (supply of a drive energy source) can be improved more by combining two or more. For example, taking into account a combination of vehicle inclination and vehicle speed, when an increase in the remaining amount of fuel is detected, the displacement of the inclination is not detected at that timing, and refueling is only performed when a stop of the vehicle is detected. It may be determined that the error has occurred.

  In addition, the presence or absence of fuel supply (supply of drive energy source) can be directly determined by using a supply sensor 302 that detects the supply amount of the drive energy source, such as a fuel flow rate sensor provided in the fuel supply port. In this case, the presence / absence of fuel supply (supply of drive energy source) can be accurately determined without detecting an increase in the remaining amount of fuel by the level sensor 301 or the like.

  Using the method described above, the control device 10 stores the timing at which it is determined that the drive energy source is supplied to the vehicle in the RAM 13.

  Next, the position acquisition function 1103 will be described. The control device 10 acquires vehicle position information at the timing when the drive energy source is supplied. The position detection device 510 detects vehicle position information. The position detection device 510 stores the current position of the vehicle and its detection timing in association with each other. The position detection device 510 may detect the position of the vehicle using satellite positioning data such as GPS (Global Positioning System), or may detect the position of the vehicle using radio waves for wireless communication. Further, it is possible to use a commonly used car navigation system such as means for receiving radio waves transmitted from positioning satellites with a GPS antenna and positioning the current position of a moving body such as a vehicle as absolute position information. . Alternatively, the position of the vehicle may be measured using autonomous navigation in which a current position is estimated by a cumulative calculation method based on positioning data input from a gyro sensor and a distance sensor attached to a wheel. It is also possible to refer to the map database and use a method of increasing the position detection accuracy by a map matching method that matches the movement of the vehicle with the road on the map.

  Then, the control device 10 causes the RAM 13 to store the position at the timing when it is determined that the drive energy source has been supplied to the vehicle.

Next, the type information acquisition function 11 will be described. The control device 10 acquires information related to the type of drive energy source. The energy type data (memory) 202 included in the vehicle controller 200 of each vehicle stores the type of driving energy source used by the own vehicle. The control device 10 accesses the energy type data (memory) 202 and reads the type of the driving energy source used by the host vehicle. The control device 10 associates the acquired type of drive energy source with a vehicle ID that identifies the host vehicle.

In the case of an electric vehicle, the supplied driving energy source is electricity, and in the case of an LP gas vehicle, the supplied driving energy source is LP gas. Thus, if the supplied drive energy source is a single type, the unit price of the drive energy source to be acquired is also determined to be one type.

On the other hand, the vehicle may be able to use multiple types of drive energy sources. For example, when high-octane gasoline or regular gasoline can be used in gasoline, the control device 10 acquires information on the type of drive energy source using the following method.

The control device 10 can acquire information about the fuel type based on the output signal of a knock sensor provided to adjust the air fuel efficiency (ratio of air to fuel) and ignition timing of the vehicle, which can be acquired via the vehicle controller 200. To get. Moreover, the control apparatus 10 acquires the information regarding the type of fuel based on output signals, such as a liquid sensor and a gas sensor which detect the component of the liquid fuel or the vaporized fuel in a fuel container.

Moreover, in a flex fuel vehicle, ethanol mixed fuel or the like may be supplied. If there is a possibility that multiple types of drive energy sources to be supplied coexist in a single fuel tank of a single vehicle type, use the knock sensor, gas sensor, liquid sensor, etc. described above to determine the fuel type in the tank. And the type of drive energy source used by the vehicle is acquired. As the liquid sensor, for example, a sensor that utilizes the fact that the refractive index and dielectric constant of the liquid differ depending on the type of fuel and the mixing ratio can be used. By using such a liquid sensor, it is possible to determine the composition of the fuel and other driving energy sources being supplied or the fuel and other driving energy sources stored in the on-vehicle tank.

In addition, a vehicle using a plurality of energy may include a plurality of supply ports and fuel tanks. For example, a plug-in hybrid vehicle includes a normal gasoline filling port and a gasoline tank, and also includes a power plug and a rechargeable battery. In addition, a bi-fuel vehicle that can use hydrogen and gasoline has a hydrogen tank and a gasoline tank separately. In such a case, the type of the newly supplied drive energy source is acquired by monitoring both sensors (remaining amount sensor and pressure sensor) together.

  Next, the unit price acquisition function 1105 will be described. The control device 10 acquires the unit price calculated based on the position information when the drive energy source is supplied from the center 2000.

  Specifically, the control device 10 generates a unit price request (command) for requesting the center 200 to acquire a unit price. This unit price request includes at least the position information when the supply of the driving energy source is determined and the communication address of the host vehicle.

  Furthermore, in addition to the position information of the vehicle, the control device 10 includes a time when the drive energy source is supplied to the unit price request, a type of the drive energy source used by the host vehicle for driving, and / or a vehicle ID for identifying the host vehicle. Can be included.

  In response to the unit price request, the center 2000 refers to the unit price information 2210 based on the position information when the driving energy source included in the unit price request is supplied, the supply time, and the type of the driving energy source, and sets the unit price. calculate. Then, the center 2000 sends the unit price to the communication address of the vehicle included in the unit price request.

  The control device 10 acquires information on the unit price according to the positional information when the driving energy source is supplied according to the request.

  The control device 10 controls communication between the communication device 700 of the host vehicle and the communication device 2300 of the center 2000 by the vehicle-side communication control function 1106 in order to execute transmission of the unit price request and acquisition of the unit price.

  The control device 10 immediately sends the unit price request generated immediately after determining that the drive energy source has been supplied to the center 200. Since the latest unit price is the most accurate, it is preferable that the unit price request is sent to the center 2000 immediately after the drive energy source is supplied. However, when it is difficult to communicate immediately after the supply of the drive energy source, the unit price request is stored for a certain period or a certain amount of history (that is, a predetermined number of times of refueling) in the RAM 13 and communication with the center 2000 is possible. Thus, a plurality of unit price requests may be sent to the center 2000. In this case, it is a condition that the supply time of the driving energy source included in the unit price request does not exceed the information storage period of the unit price information 2210 of the center 2000.

  In addition, the control device 10 may send a unit price request to the center 2000 together with downloading traffic information, guidance information, etc., and uploading vehicle information (travel history, etc.).

Next, the consumption calculation function 1107 will be described. The control apparatus 10 calculates | requires the consumption of a drive energy source using the variation | change_quantity of the residual amount of the drive energy source which a vehicle accumulate | stores.

The control apparatus 10 calculates | requires the consumption of the drive energy source in the calculation reference | standard period of the consideration mentioned later. For example, when determining the consumption amount of the drive energy source from the start of travel to the end of travel, the control device 10 determines the difference between the remaining amount of the drive energy source at the start of travel and the remaining amount of the drive energy source at the end of travel. To determine the amount of change in the remaining amount of the drive energy source. By using the same method, the consumption amount of the driving energy source is calculated while the vehicle travels a predetermined distance for one day, one week, one month when traveling on the expressway from the current position to the destination. The period for obtaining the consumption amount of the driving energy source is arbitrarily set.

In addition, the control device 10 stores the remaining amount of the driving energy source stored in the vehicle at a predetermined period, and uses the amount of change in the remaining amount of the driving energy source between arbitrary points in time to consume the driving energy source between the points in time. The amount can be determined.

In a vehicle using a plurality of driving energy sources, there is a specific relationship between the amount of change in the remaining amount of the driving energy source and the consumption amount of the driving energy source.

For example, plug-in hybrid vehicles and hydrogen / gasoline bi-fuel vehicles run using different or different driving energy sources such as electricity and gasoline or hydrogen and gasoline. The consumption pattern of the driving energy source (whether electricity is used, gasoline is used, or both are used) corresponding to the speed, acceleration, and remaining amount of fuel is stored in the vehicle controller 200 in advance as a vehicle model.

The control device 10 refers to the consumption model of the drive energy source based on the speed, acceleration, and remaining amount of fuel, and calculates the consumption amount. When the vehicle running pattern is applied to the consumption model, the utilization ratio of each energy can be calculated. The control apparatus 10 calculates | requires the consumption according to this utilization ratio, and adds the charge according to this consumption or presents it separately as consideration. If a navigation device installed in the vehicle is used, the traveling speed, acceleration, number of starts and stops of the vehicle on the planned traveling route of the vehicle can be estimated using the traffic information, the number of intersections, the driving pattern history of the driver, etc. It is.

Next, the consideration calculation function 1108 will be described. The control device 10 calculates a consideration for energy consumption based on the acquired unit price and the consumption amount of the driving energy source of the vehicle. The control device 10 calculates the consideration of the consumption amount of the driving energy source in the above-described preset calculation reference period of the consideration.

First, the control device 10 calculates the consideration for the supplied drive energy source by multiplying the change amount of the remaining amount of the drive energy source when the drive energy source is supplied to the vehicle by the unit price acquired from the server 2000. . The unit price acquired from the server 2000 is a unit price calculated based on position information when the driving energy source is supplied to the vehicle.

By this process, the price of the supplied driving energy source can be obtained. The control device 10 stores the calculated value of the driving energy source and the timing at which the driving energy source is supplied in association with each other.

The drive energy source supplied to the vehicle is not limited to the drive energy source supplied at a time. That is, drive energy sources with different unit prices may be supplied.

For this reason, the control apparatus 10 calculates | requires the representative value of the value of the whole drive energy source supplied to a vehicle.

Specifically, the control device 10 stores the value of the supplied drive energy source for each supply timing, and uses the value of the drive energy source stored for each supply timing to determine the drive energy source supplied to the vehicle. The representative value of the unit price is obtained, and the consideration of the consumed energy is calculated based on the calculated representative value of the unit price and the consumption amount of the driving energy source.

For example, the control device 10 obtains a ratio of the supply amount in a predetermined number of supplies including the recent supply, and represents a weighted average value of the consideration of the consumed energy according to this ratio as a representative value of the unit price of the driving energy source stored in the vehicle. Calculate as The drive energy source subject to the weighted average may be a drive energy source supplied in a period retroactive from the present time, or the current position from the start of travel to the end of travel corresponding to the calculation period of the consideration. When traveling on a highway from the destination to the destination, it may be during one day, one week, one month, or other periods while the vehicle travels a predetermined distance.

As described above, in addition to the method of calculating the value of the driving energy source stored in the vehicle based on the supply amount, the fuel in the fuel tank of the vehicle is calculated based on the unit price of the fuel remaining in the fuel tank of the vehicle. A method for calculating the consideration can be considered. When the unit price frequently fluctuates, when the drive energy source stored in the vehicle includes a plurality of unit drive energy sources, it is necessary to consider each unit price of the drive energy source stored in the vehicle.

FIG. 6 is a diagram schematically showing driving energy sources with different unit prices stored in one vehicle. In FIG. 6, the drive energy source (fuel) supplied in the past is shown in the lower layer, and the newly supplied drive energy source is superimposed on the upper layer. The tank (storage body) for the driving energy source of the vehicle shown in FIG. 6 stores driving energy of three kinds of prices by supplying three times.

Since the vehicle is not supplied with the driving energy source but also consumes it, the existence ratio of the driving energy source for each unit price that the vehicle stores changes. For this reason, the control apparatus 10 records the supply amount of the drive energy source supplied to the vehicle and the consumption amount of the drive energy source, manages the balance of the drive energy source stored in the vehicle, and for each unit price stored in the vehicle. Calculate the abundance ratio of the driving energy source. The control device 10 uses the detection signal of the fuel injection amount control sensor 304 in addition to the detection signal of the level sensor 301 in calculating the fuel consumption.

  The control device 10 uses the concept of a first-in first-out (FIFO) method for managing the balance of the drive energy source stored in the vehicle, assuming that the drive energy source supplied earlier is consumed first. The existence ratio of the driving energy source for each unit price stored by is calculated. That is, until the drive energy source supplied at the earliest (old) timing is used up, the price of the consumed energy is calculated using the unit price of the drive energy source supplied at the earliest (old) timing. When the drive energy source supplied at the earliest (old) timing is used up, the price of the consumed energy is calculated using the unit price of the drive energy source supplied at the next (oldest) timing. Therefore, when the unit price of the driving energy source is switched in the middle of the calculation reference period for calculating the consideration, and the driving energy sources having different unit prices are mixed, the weighted average consideration is calculated according to the consumption amount.

  In the present embodiment, using the concept of a first-in first-out (FIFO) method, the consideration of energy consumption is calculated by the following method.

  The control device 10 adds the calculated value of the driving energy source in order of the new supply timing (tracing back from the latest supply of the price calculation timing). The amount obtained by dividing the total amount of the driving energy source related to the added total consideration and the remaining amount of the driving energy source stored in the vehicle at the time of the calculation by the remaining amount of the driving energy source stored in the vehicle, This is the representative unit price of the drive energy source. Then, the consideration of the consumed energy is calculated by multiplying the representative value of the consideration by the consumption amount of the driving energy source. According to this method, the representative value of the unit price of the drive energy source stored in the vehicle, excluding the drive energy source consumed by the first-in first-out, can be obtained. For this reason, the consideration of energy consumption can be calculated based on the unit price of the drive energy source actually stored in the vehicle.

Furthermore, the control apparatus 10 arranges the calculated value of the consumed energy for each calculation timing, and calculates the total period of the value of the consumed energy included in the predetermined period. That is, the control apparatus 10 calculates | requires the cost of fuel cost and other energy consumption for every predetermined period. With this information, the user can know the value of energy consumption in a period such as one day, one week, or one month.

Finally, the output control function 1109 will be described. The control device 10 causes the output device 400 to output the calculated energy consumption consideration information. The control device 10 outputs the calculated period total amount of energy consumption in association with a predetermined period.

The output device 400 includes a display 420 and a speaker 430. The display 420 is an information display screen such as a liquid crystal panel or an LED panel. The speaker 430 is an audio device for in-vehicle audio.

FIG. 7 is a diagram illustrating an example of information related to the value of energy consumption. FIG. 7 is an example of presentation of the fuel price. The horizontal column denoted by reference numeral 71 in FIG. 7 is information indicating the fuel price from the start of the engine to the present, that is, in units of drives. The horizontal column indicated by reference numeral 72 in FIG. 7 is information indicating the fuel price for each week, that is, this week. The horizontal column indicated by reference numeral 73 in FIG. 7 is information indicating the fuel price for this month, that is, this month. In addition, a horizontal column “this week's fuel price” indicated by reference numeral 72 is selected and highlighted. In this case, the information corresponding to the fuel price for each week, that is, the past weekly fuel consumption history is indicated by reference numeral 74. Note that the control device 10 displays the fuel price (the value of the driving energy source), the fuel consumption, the travel distance, and the fuel consumption as the consideration information of the energy consumption. With such information, the value of the driving energy source can be transmitted to the user more easily.

Next, based on the flowchart of FIG. 8, the operation procedure of the calculation processing for the consumption energy consideration according to the present embodiment will be described.

First, in step S101, the position detection device 510 starts monitoring the current position of the vehicle.

In step S102, the level sensor 301 monitors the remaining amount of fuel and other driving energy sources of the vehicle.

In subsequent step S <b> 103, the control device 10 determines whether or not an increase in fuel exceeding a predetermined threshold is detected from the detection value of the level sensor 301. If an increase in fuel exceeding a predetermined threshold is detected, the process proceeds to step S104. If not detected, the process returns to step S101 and monitoring is continued.

In subsequent step S104, the control device 10 receives the detection of the increase in fuel, and further considers the establishment of a condition for accurately determining whether or not fuel has been supplied. Using the above-described method, the control device 10 determines whether the engine has been stopped and restarted, the speed has been displaced more than a predetermined value, or the vehicle position is more than a predetermined distance before and after the increase in fuel is detected (within a predetermined time). It is determined whether the vehicle has been displaced by an inclination greater than a predetermined value, whether the fuel filler has been opened or closed, whether the fuel filler has been attached to or detached from the fuel filler, and whether the fuel has passed through the fuel filler path. These conditions may be one or a plurality of conditions. When the preset condition is satisfied, that is, when it is determined that the possibility of refueling is high, the process proceeds to step S105, and when it is determined that it is not, the process returns to step S101 and monitoring is continued.

In step S105, the control device 10 records the current position of the vehicle at the timing when refueling is detected, that is, the position information when the supply of the drive energy source is determined.

In subsequent step S <b> 106, the control device 10 transmits to the center 2000 a unit price request including the vehicle position information detected in step S <b> 105 and the vehicle fuel type separately acquired in advance. The center 2000 refers to the unit price information 2210 in which the drive energy source supply location and the unit price of the drive energy source are associated in advance based on the position information included in the unit price request and the fuel type, and the unit price of the drive energy source of the vehicle Is calculated and sent to the vehicle side. The control device 10 stores the fuel unit price acquired from the center 2000. In the latter step, when the fuel unit price is calculated by the first-in first-out method or the weighted average method, the fuel supply amount (supply amount of the driving energy source) is also stored at the same time.

Further, in step S107, the control device 10 calculates the unit price of the driving energy source stored in the vehicle, for example, gasoline in the fuel tank. When the first-in first-out method or weighted average method described above is used as the unit price calculation method, the fuel (driving energy source) currently stored in the vehicle based on the acquired unit price and supply amount and the history of the unit price and supply amount supplied in the past. ) Or unit price of consumed fuel (drive energy source).

In step S <b> 108, the control device 10 determines whether or not there is a request for presenting the value of energy consumption input from the user. When the presentation request is input, the process proceeds to step S109. If there is no request, the process returns to step S101 to continue monitoring.

Further, in step S109, the control device 10 calculates the value of the driving energy source consumed during the predetermined calculation reference period. For example, from the start of operation to the end of operation, or from the beginning of the week to the end of the week, from the beginning of the month to the end of the month, the amount of consumption from a predetermined time to the present is acquired, and this is multiplied by the unit price calculated in step S107, Is calculated.

In step S110, the control device 10 presents the price calculated in step S109 using the display 420 or the speaker 430. The control device 10 is configured as described above and presents the present invention that presents the value of the driving energy source according to the consumption amount, for example, in units of drives, weeks, months, and so on. Play.

According to the energy information providing unit 1 of the present embodiment, the drive energy source supplied to the vehicle even when there is no facility for providing unit price information on the drive energy source supply location side such as a gas station. Therefore, it is possible to provide highly accurate information on the price of energy consumption.

That is, the energy information providing unit 1 of the present embodiment calculates the supply location of the drive energy source and the unit price of the drive energy source calculated based on the position information of the vehicle when the drive energy source such as gasoline is supplied. The unit price of the driving energy source of the vehicle calculated with reference to the fuel unit price information associated in advance is acquired, and the price of the consumption of the driving energy source is calculated from the acquired unit price and the consumption of the driving energy source. Therefore, the actual unit price of the supplied drive energy source can be acquired automatically, so even if there is no facility for providing unit price information on the drive energy source supply location side, high-accuracy energy consumption can be achieved. Information about consideration can be provided.

Moreover, since the energy information provision unit 1 of this embodiment judges that the drive energy source was supplied to the vehicle when the remaining amount of the drive energy source increases, the timing at which the drive energy source such as gasoline is supplied is determined. It can be detected accurately. As a result, the energy information providing unit 1 of the present embodiment can provide highly accurate information on the value of the consumed energy, as in the above-described invention.

Further, the energy information providing unit 1 according to the present embodiment determines whether or not the driving energy source is supplied to the vehicle based on the increase in the remaining amount of the driving energy source and the information on the stop and restart of the engine of the vehicle. Therefore, it is possible to accurately detect the timing when the driving energy source such as gasoline is supplied. As a result, similarly to the above-described invention, the energy information providing unit 1 according to the present embodiment can provide highly accurate information on the value of energy consumption.

In addition, the energy information providing unit 1 of the present embodiment determines whether or not the driving energy source is supplied to the vehicle based on the increase in the remaining amount of the driving energy source and the change in the position of the vehicle. It is possible to accurately detect the timing when the driving energy source is supplied. In other words, since the vehicle is stopped at the time of supplying the driving energy source such as gasoline, the driving energy source is supplied by monitoring that the moving distance of the vehicle is less than the predetermined value, that is, the state where it is almost as much as the stopping. The detected timing can be accurately detected. As a result, the energy information providing unit 1 of the present embodiment can provide highly accurate information on the value of the consumed energy, as in the above-described invention.

Further, the energy information providing unit 1 of the present embodiment determines whether or not the driving energy source is supplied to the vehicle based on the increase in the remaining amount of the driving energy source and the speed or acceleration of the vehicle. The timing at which the drive energy source is supplied can be accurately detected. In other words, since the vehicle is stopped when a driving energy source such as gasoline is supplied, the driving energy source is monitored by monitoring that the speed / acceleration of the vehicle is less than a predetermined value, that is, almost in the state of stopping. The supplied timing can be accurately detected. As a result, the energy information providing unit 1 of the present embodiment can provide highly accurate information on the value of the consumed energy, as in the above-described invention.

Further, the energy information providing unit 1 of the present embodiment determines whether or not the driving energy source is supplied to the vehicle based on the increase in the remaining amount of the driving energy source and the inclination of the vehicle. The timing when the source is supplied can be accurately detected. As a result, it is possible to eliminate the fact that the fuel level rises as a result of the vehicle being tilted temporarily and is erroneously determined as fueling. As a result, the energy information providing unit 1 of the present embodiment can provide highly accurate information on the value of the consumed energy, as in the above-described invention.

In addition, the energy information providing unit 1 of the present embodiment determines whether the driving energy source is supplied to the vehicle based on the increase in the remaining amount of the driving energy source and the opening / closing information of the energy source supply path. It is possible to accurately detect the timing when the driving energy source such as is supplied. As a result, the energy information providing unit 1 according to the present embodiment can provide highly accurate information on the value of the consumed energy as in the above-described invention.

Further, the energy information providing unit 1 of the present embodiment supplies the drive energy source to the vehicle based on the increase in the remaining amount of the drive energy source and the connection information between the vehicle energy supply path and the external energy source supply device. Therefore, it is possible to accurately detect the timing when the driving energy source such as gasoline is supplied. As a result, the energy information providing unit 1 of the present embodiment can provide highly accurate information on the value of the consumed energy, as in the above-described invention.

In addition, the energy information providing unit 1 according to the present embodiment determines whether or not the driving energy source is supplied to the vehicle based on the supply amount of the driving energy source, so that the driving energy source such as gasoline is supplied. Can be accurately detected. As a result, the energy information providing unit 1 of the present embodiment can provide highly accurate information on the value of the consumed energy, as in the above-described invention. Since the flow rate of the drive energy source such as fuel passing through the supply path such as the fuel filler port is detected, it is possible to accurately determine whether or not the drive energy source is supplied, and also to accurately grasp the supply amount such as the fuel supply amount. Can do. In addition, by considering the amount of change in the supply amount of the drive energy source, it can be determined whether or not the drive energy source has been supplied to the vehicle more accurately.

Further, the energy information providing unit 1 of the present embodiment gives the vehicle the unit price associated with the drive energy source supply location closest to the vehicle position when it is determined that the drive energy source is supplied. Calculated as the unit price of the supplied drive energy source. As described above, since the position at which the vehicle is present at the timing when it is determined that the drive energy source is supplied can be used as a key, the gasoline station (supply location) to which the vehicle has supplied the drive energy source such as gasoline can be estimated. Unit price can be determined. Further, if the unit price information 2210 does not include information on the gas station where the vehicle actually supplies gasoline, the prices of the nearby gas stations can be obtained even if the information is old. Since prices of driving energy sources such as gasoline tend to vary depending on regions, a reliable unit price can be obtained even if a substitute value is used.

Further, the energy information providing unit 1 of the present embodiment uses the unit price associated with the predetermined area to which the vehicle position belongs when it is determined that the drive energy source is supplied as the unit price of the drive energy source supplied to the vehicle. Therefore, an accurate unit price can be obtained as in the above invention. Even if the unit price information 2210 does not include information on the gas station where the vehicle actually supplies gasoline, the price of gasoline or the like in that region can be obtained. Since prices of driving energy sources such as gasoline tend to vary depending on regions, a reliable unit price can be obtained even if a substitute value is used.

In addition, the energy information providing unit 1 of the present embodiment calculates the unit price of the type of driving energy source supplied to the vehicle based on the position information acquired from the energy information providing device and the type information of the driving energy source. As in the above invention, an accurate unit price according to the type can be obtained. In calculating the unit price, the control device 10 of the present embodiment determines the type of driving energy source (alcohol fuel or electricity such as gasoline, liquefied natural gas, biofuel, hydrogen, methanol, etc., or gasoline regular gasoline, high-octane gasoline (high octane gasoline). ), Light oil, etc.), the correct unit price can be calculated.

Further, the energy information providing unit 1 of the present embodiment calculates the value of the supplied drive energy source for each supply timing, and uses the value of the drive energy source to represent the representative value of the unit price of the drive energy source stored in the vehicle. And the consideration of energy consumption is calculated using the representative value of the unit price. For this reason, even when the vehicle stores a plurality of drive energy sources having a unit price at the same time, it is possible to obtain a price for energy consumption based on the representative value of the unit price weighted according to the supply amount. That is, it is possible to calculate the consideration of energy consumption that reflects the actual price (actual purchase price).

In the above-described invention, the energy information providing unit 1 according to the present embodiment adds the considerations of the supplied drive energy sources in the order of supply timing, and monitors and monitors the amount of drive energy sources related to the added total consideration. An amount obtained by dividing the total price that is equal to the remaining amount of the driving energy source stored in the vehicle by the remaining amount of the driving energy source stored in the vehicle is obtained as a representative value of the unit price of the driving energy source. Thus, the unit price of the recently supplied drive energy source is reflected in accordance with the concept that the drive energy source supplied first is consumed first, using the concept of first-in first-out (FIFO) method. Unit price can be calculated. According to this method, the representative value of the unit price of the drive energy source stored in the vehicle, excluding the drive energy source consumed by the first-in first-out, can be obtained. For this reason, the consideration of energy consumption can be calculated based on the unit price of the drive energy source actually stored in the vehicle.

In addition, the energy information providing unit 1 of the present embodiment sorts the calculated consideration of the consumed energy for each calculation timing, and calculates the total amount of the consumed energy included in the predetermined period. It is possible to present the value of energy consumption, such as drive unit, week unit, and month unit, arranged by period. With such information, the value of the driving energy source can be transmitted to the user more easily.

  FIG. 9 is a block diagram of the energy information providing unit 1 according to this embodiment. As shown in FIG. 9, the configuration of the energy information providing unit 1 of the second embodiment is basically the same as the configuration of the energy information providing unit 1 of the first embodiment shown in FIG.

The fuel information providing apparatus 100 of the energy information providing unit 1 of the second embodiment transmits and receives information from the navigation apparatus 500. The fuel information providing apparatus 100 and the navigation apparatus 500 accept input from the input apparatus 600.

Hereinafter, about the energy information provision unit 1 of 2nd Embodiment, it demonstrates centering on a different point from 1st Embodiment, and the description which demonstrates the energy information provision unit 1 of 1st Embodiment is used for the overlapping part.

The navigation device 500 included in the in-vehicle device 1000 of this embodiment includes a position detection device 510, a destination setting function 520, a route guidance function 530, a map database 540, and a storage device 550. The position detection device 510 of the present embodiment corresponds to the position detection device 510 of the first embodiment. The destination setting function 520 of the navigation device 500 accepts a destination input from the user via the input device 600. Then, the route guidance function 530 searches for a route from the current position to the destination. Further, the route guidance function 530 refers to the map database 540 and the guidance information 551 in the storage device 550, and generates route guidance information including information on the route and facilities on the route and other points of interest (POI). The route guidance function 530 presents guidance information to the user via the display 420 and the speaker 430 of the output device 400.

Next, functions of the arithmetic device 2100 of the center 2000 and the control device 10 of the fuel information providing device 100 according to the present embodiment will be described.

FIG. 10 is a diagram illustrating an example of functional blocks of the fuel information providing apparatus 100 and the center 2000 according to the second embodiment. As shown in FIG. 2, the functions of the arithmetic device 2100 of the center 2000 and the control device 10 of the fuel information providing device 100 of this embodiment are basically the same as those of the first embodiment.

As shown in FIG. 10, the consideration calculation function 1108 of the control device 10 of the fuel information providing device 100 cooperates with the navigation function 5001 of the navigation device 500.

Hereinafter, the supply determination function 1102 of the fuel information providing apparatus 100 of this embodiment will be described. When the remaining amount of the drive energy source increases and the navigation function 5001 searches for a drive energy source supply station within a predetermined distance range of the host vehicle, the control device 10 of this embodiment has a drive energy source in the vehicle. Judge that it was supplied.

  Specifically, the control device 10 includes a supply location search function 5002 (one aspect of the navigation function) for searching for a drive energy source supply location that is within a predetermined distance range of the acquired current position of the vehicle. The control device 10 may cause the navigation device 500 outside the fuel information providing device 100 to search for a driving energy source supply station that is within a predetermined distance range of the current position of the vehicle.

Further, when the remaining amount of the driving energy source increases, the control device 10 searches for the driving energy source supply station within a predetermined distance range of the current position of the vehicle at the timing when the remaining amount of the driving energy source increases. Determines that a drive energy source has been supplied to the vehicle.

The control device 10 according to the present embodiment can improve the accuracy of determining whether or not a drive energy source is supplied to the vehicle by using the supply place search function 5002 of the navigation function 5001.

  FIG. 11 is a diagram for explaining a method for monitoring the supply timing of the drive energy source according to the second embodiment. 11A shows the monitoring result of the remaining fuel amount shown in FIG. 4, and FIG. 11B shows whether there is a fueling facility (driving energy source supply station) around the current position at the driving energy source supply timing. It is a figure which shows the search result of whether or not.

The control device 10 causes the navigation device 500 to search whether there is a fueling facility (driving energy source supply station) around the current position in a predetermined cycle, and records the result. For example, if there is a fueling facility within 10 m of the current position at the timing of reference numeral 41, the control device 10 can search for the fueling facility around the current position, and the timing column of reference numeral 41 in FIG. A white circle is attached to. On the other hand, if there is no refueling facility, the control device 10 assumes that the refueling facility could not be searched and places a white circle in the timing column.

As shown in FIG. 11B, reference numerals 41 to 44 indicate timings at which an increase in the remaining amount of the drive energy source is detected, which is the same as the example of the first embodiment shown in FIGS. As shown in FIG. 11B, at the timings of reference numerals 41 and 44, the fueling facility can be searched around the current position, but at the timings of reference numerals 42 and 43, the fueling facility cannot be searched around the current position. That is, the increase in the remaining amount of fuel at the timings 41 and 44 occurs at the fueling facility, and the increase in the remaining amount of fuel at the timings 42 and 43 does not occur at the fueling facility. As a result, the control device 10 determines that refueling has been performed at the timings of reference numerals 41 and 44, and determines that refueling has not been performed at the timings of reference numerals 42 and 43.

However, since an error may also occur in the search result of the fueling facility, the signal indicating the stop / restart of the engine detected by the engine drive sensor 303 or the speed / acceleration sensor 305 described in the first embodiment is used. It is determined whether or not the drive energy source has been supplied in consideration of the detected signal indicating the movement of the vehicle. In this case, the control device 10 determines whether or not the driving energy source has been supplied based on whether or not the vehicle located in the vicinity of the fueling facility has turned off the engine for a predetermined time or more, and the vehicle located in the vicinity of the fueling facility. It is determined whether or not the drive energy source has been supplied based on whether or not has stopped for a predetermined time or longer.

  In addition, the remaining amount monitoring function 1101 and the supply determination function 1102 of the control device 10 of the present embodiment can execute the same processing as in the first embodiment.

  Further, the control device 10 of the present embodiment includes the position acquisition function 1103, the type information acquisition function 1104, the unit price acquisition function 1105, the vehicle side communication control function 1106, and the consumption calculation function 1107 described in the first embodiment.

  Next, the consideration calculation function of the control apparatus 10 of this embodiment is demonstrated. The control device 10 according to the present embodiment calculates a consideration of energy consumption according to the amount of consumption predicted from the distance of the route from the current position to the destination. That is, the control device 10 according to the first embodiment calculates the consideration of the energy consumption based on the traveling performance. In the present embodiment, the control device 10 further calculates the consideration of the energy consumption predicted to be consumed on the planned travel route. Can do.

  Specifically, the control device 10 includes a distance calculation function 5003 (an aspect of the navigation function) that calculates the distance of a route from the current position of the vehicle to the destination. The control device 10 may cause the navigation device 500 outside the fuel information providing device 100 to calculate the distance of the route from the current position of the vehicle to the destination. The navigation device 500 can acquire information such as the planned travel distance, the planned travel road type, the planned travel road link, the transit time of the planned travel road link, and the estimated arrival time based on the route calculation result.

  Moreover, the control apparatus 10 acquires fuel consumption information. The fuel consumption information is obtained using the consumption amount of the drive energy source and the travel distance in the past travel. Specifically, the control device 10 records the consumption amount of the driving energy source for each traveling or every predetermined period and the traveling distance for each traveling or every predetermined period, and divides this traveling distance by the consumption amount of the driving energy source. And ask for fuel consumption information.

  Further, the control device 10 predicts the consumption amount of the driving energy source based on the calculated fuel consumption information and the predicted distance to the destination.

  The control device 10 stores the consumption amount of the driving energy source for each road link and for each statistical travel time of the link, that is, for each degree of congestion, and drives for each link based on the estimated link passage time of the planned road link. The estimated consumption of energy sources can be determined.

  Further, the control device 10 calculates the consideration of the energy consumption necessary for traveling on the route based on the unit price acquired from the center 2000 and the predicted consumption amount of the driving energy source of the vehicle. The control device 10 calculates the required energy consumption for each of a plurality of routes from the current location to the destination.

  In addition, the control device 10 causes the output device 400 to output the consideration of the energy consumption required for traveling on each calculated route.

  FIG. 12 shows an example of presentation of the value of energy consumption necessary for traveling on the route presented on the display 420. FIG. 12 shows image information presented when five types of route candidates A to E (routes A to E) are displayed. In FIG. 12, route A indicated by reference numeral 121 among routes A to E is selected, and map information indicating route A is displayed. The control device 10 displays routes A to E in association with the calculated consumption amount of the driving energy source necessary for traveling and the consideration of the consumed energy, together with the required time and the highway fee. As a result, the user can select the route in consideration of the predicted consumption amount of the driving energy source of the route to be traveled and the value (fuel cost) thereof.

Next, based on the flowchart of FIG. 8, the operation procedure of the calculation processing for the consumption energy consideration according to the present embodiment will be described.

  The processing from step S201 to S207 is common to the processing from step S101 to S107 of FIG. 8 showing the operation procedure of the first embodiment. Here, in order to avoid redundant explanation, the explanation of the processing from step S101 to S107 of the first embodiment is used for the processing from step S201 to S207, and the processing after step S208 will be explained.

  Subsequent to step S207, in step S208, the control device 10 determines whether or not there is a route search request. If there is a request, the process proceeds to step S209. If there is no request, the process returns to step S201 to continue monitoring.

In subsequent step S209, the control device predicts consumption based on the route calculation result of the navigation device 500 using the above-described method.

In subsequent step S210, the control device 10 multiplies the predicted consumption calculated in step S109 by the unit price obtained in step S107 to calculate a consideration of energy consumption necessary for traveling on the route.

Next, in step S211, the control device 10 presents the consideration of the energy consumption calculated in step S110 in association with the travel route. When there are a plurality of travel route candidates, each is presented.

When the supply place is searched, it is determined that the drive energy source is supplied to the vehicle, so that it is possible to improve the accuracy of the determination as to whether the drive energy source is supplied to the vehicle.

In addition, since the consumption of the driving energy source used from the current position to the destination and the unit price acquired from the center 2000 are calculated, the consideration of the energy consumption required for traveling the route is calculated. Can know the predicted consumption of the driving energy source and the price (fuel cost) of the driving route, and can select the route in consideration of these.

Since there is no need for price communication facilities such as DSRC (Dedicated Short Range Communication) on the drive energy supply station (fueling facility) side, and if the vehicle has a communication function, it can provide the cost of energy consumption. It is also advantageous from the side.
