(Fuel estimation formula in navigation device 300)
When the vehicle starts traveling, the navigation device 300 calculates the fuel consumption using the preset vehicle acceleration information and the vehicle speed. Specifically, the navigation device 300 calculates the fuel consumption using the following equation (1). The following formula (1) is called “fuel consumption estimation formula (consumption energy estimation formula)”, and the fuel consumption calculated using the following formula (1) is called “estimated fuel consumption (estimated energy consumption)”. Note that the fuel consumption estimation formula is not limited to the following formula (1), and any formula can be used as long as it can acquire vehicle acceleration information and speed information and estimate fuel consumption.

  In the above equation (1), time (h) and second (s) are mixedly used as units representing time, but this employs speed (km / h) as a unit of speed. This is because the second (s) is adopted as the unit time for estimating the fuel consumption. When it is desired to align these units, an appropriate calculation may be performed on each numerical value.

(Outline of the acquisition process in the navigation device 300, part 1)
Next, an example of acquisition processing in the navigation device 300 will be described. In the first embodiment, as a method for obtaining the threshold value of the vehicle speed, the vehicle speed is maintained at 40 km / h when the vehicle speed reaches 40 km / h after the vehicle starts and accelerates. Furthermore, the vehicle is run until the vehicle travel distance reaches 200 m, and the speed 5 seconds after the vehicle starts is set as a threshold value.

  The navigation device 300 acquires the vehicle speed threshold value before the vehicle on which the device is installed starts traveling, or when the vehicle information on the vehicle on which the device is installed is input by the user. To inform. The vehicle information is information used when the navigation device 300 calculates the estimated fuel consumption using the above equation (1), and includes, for example, the displacement, weight, vehicle height, vehicle width, and the like. Hereinafter, the navigation apparatus 300 calculates the estimated fuel consumption by setting the displacement, weight, height, and width of the vehicle to 0.66 L, 800 kg, 166 cm, and 147 cm, respectively.

  4A to 4C are explanatory diagrams illustrating tables held by the navigation device. For example, the navigation device 300 calculates that the estimated fuel consumption per unit time when the vehicle accelerates at the acceleration after assuming that the vehicle starts (speed = 0 km / h) and travels at a constant acceleration. Specifically, when the vehicle acceleration range for calculating the estimated fuel consumption is set to 4 km / h / s to 8 km / h / s, the navigation device 300 may be, for example, 4 km / h / s, 6 km / h / s. s, the estimated fuel consumption when the vehicle travels at an acceleration of 8 km / h / s is calculated.

  Further, the navigation device 300 maintains the vehicle speed when the speed of the vehicle traveling in the acceleration pattern reaches a predetermined speed, and thereafter the vehicle per unit time until the vehicle travel distance reaches the predetermined distance. Calculate the estimated fuel consumption. Specifically, the navigation device 300 maintains the vehicle speed at 40 km / h when the speed of the vehicle traveling in the acceleration pattern exceeds 40 km / h, and estimates until the travel distance of the vehicle reaches 200 m, for example. Continue to calculate fuel consumption.

  That is, as shown in FIGS. 4-1 (a), 4-2 (a), and 4-3 (a), the vehicle travel pattern is from the start of the vehicle until the vehicle speed reaches 40 km / h. In the first section, the acceleration pattern linearly accelerates, and in the second section in which the vehicle speed maintains 40 km / h, the speed pattern changes at a constant speed until the travel distance of the vehicle reaches 200 m.

  The navigation device 300 acquires the speed when a predetermined time has elapsed from the start of the vehicle in a vehicle that travels in the travel pattern. The speed acquired by the navigation device 300 is vehicle movement information for saving fuel consumption of the vehicle. Specifically, the user starts the vehicle so that the speed when a predetermined time has elapsed after starting the vehicle becomes the speed threshold (e start threshold) acquired by the navigation device 300, so that the user It is possible to achieve traveling that saves fuel consumption.

  Specifically, the navigation device 300 acquires, for example, a speed after 5 seconds from the start of the vehicle in the vehicle that travels in the travel pattern. As shown in FIGS. 4-1 (a), 4-2 (a), and 4-3 (a), the speeds after 5 seconds from the start of the vehicle in each traveling pattern are different. Therefore, the navigation apparatus 300 calculates the fuel consumption consumed by the vehicle that has traveled in each travel pattern, and the cumulative total fuel consumption (total fuel consumption) when the vehicle finishes traveling in a predetermined section. ) To obtain a threshold value of the vehicle speed.

  Specifically, for example, as shown in FIG. 4B, the navigation apparatus 300 calculates a speed 401_1 per unit time and calculates a speed 401_1 in a vehicle that accelerates at an acceleration of 4 km / h / s. Every time, the total travel distance 401_2 and the total fuel consumption 401_3 are calculated. And the navigation apparatus 300 is a vehicle in which the total travel distance 401_2 of the vehicle reaches 200 m in a state where the vehicle speed 401_1 after 10 seconds from the start of the vehicle at which the vehicle speed 401_1 reaches 40 km / h is maintained at 40 km / h. The total fuel consumption 401_3 is continuously calculated until 23 seconds after the start.

  Thus, the travel time (unit time) 401_0 from the start of the vehicle, the vehicle speed 401_1 when the travel time has elapsed, the total travel distance 401_2, and the total fuel consumption 401_3 are composed of a plurality of records recorded in one record. The first table 401 is completed.

  Further, for example, as shown in FIG. 4-2 (b), the navigation device 300 is adapted to the speed 401_1 and the total travel speed in a vehicle that accelerates at an acceleration of 4 km / h / s even in a vehicle that accelerates at an acceleration of 6 km / h / s. Just as the distance 401_2 and the total fuel consumption 401_3 are calculated, the speed 402_1, the total travel distance 402_2, and the total fuel consumption 402_3 are calculated.

  Further, for example, as shown in FIG. 4-3 (b), the navigation device 300 is capable of speed 401_1 and total travel in a vehicle that accelerates at an acceleration of 4 km / h / s even in a vehicle that accelerates at an acceleration of 8 km / h / s. As the distance 401_2 and the total fuel consumption 401_3 are calculated, the speed 403_1, the total travel distance 403_2, and the total fuel consumption 403_3 are calculated.

  Thus, the travel time (unit time) 402_0 from the start of the vehicle, the vehicle speed 402_1 when the travel time has elapsed, the total travel distance 402_2, and the total fuel consumption 402_3 are composed of a plurality of records. The first table 402 is completed. In addition, the travel time (unit time) 403_0 from the start of the vehicle, the vehicle speed 403_1, the total travel distance 403_2, and the total fuel consumption 403_3 when the travel time has elapsed include a plurality of records that are recorded in one record. One table 403 is completed.

  The first to third tables 401 to 403 are stored in, for example, a storage device (magnetic disk 305 or optical disk 307) of the navigation device 300.

  Next, the navigation apparatus 300 refers to the total fuel consumption 401_4, 402_4, 403_4 of the records recorded as the travel distance 200m in the first to third tables 401 to 403, and sets the table with the minimum total fuel consumption. Get the associated acceleration.

  That is, in the navigation device 300, the total fuel consumption 401_4 of the first table 401 is 13.62025, the total fuel consumption 402_4 of the second table 402 is 13.58143, and the total fuel consumption of the third table 403 With reference to 403_4 being 13.73542, it is determined that the total fuel consumption 402_4 of the second table 402 is the minimum. Then, the navigation apparatus 300 acquires the acceleration 6 km / h / s associated with the second table 402 that minimizes the total fuel consumption.

  Next, the navigation apparatus 300 acquires the speed 5 seconds after the start of the vehicle accelerated at the acquired acceleration of 6 km / h / s as the threshold value of the vehicle speed. That is, the navigation apparatus 300 refers to the speed 402_1 after 5 seconds from the start of the vehicle in the second table 402, acquires the speed 30 km / h as the vehicle speed threshold 402_5, and completes the acquisition process in the navigation apparatus 300.

  The speed of 30 km / h acquired as the vehicle speed threshold 402_5 is set such that the vehicle is started so that the speed becomes 30 km / h after 5 seconds from the start of the vehicle, thereby realizing the traveling that saves the fuel consumption of the vehicle. means.

  After that, the navigation apparatus 300 displays a message such as “Please step on the accelerator so that the speed after 5 seconds from the start is 30 km / h” based on the acquired vehicle speed threshold 402_5, for example, on the display 313 or the like. The user is notified by displaying.

(Outline of the acquisition process in the navigation apparatus 300-2)
Next, another example of acquisition processing in the navigation device 300 will be described. FIGS. 6-1 to 6-3 are characteristic diagrams showing threshold values of the vehicle speed. The navigation device 300 may acquire a threshold value of the vehicle speed as a traveling pattern in which the vehicle accelerates in stages in the first section from the start of the vehicle to the end of acceleration.

  FIG. 5 is an explanatory diagram showing the amount of change in the acceleration of the vehicle. The navigation device 300, for example, has a vehicle speed v at a time (target speed arrival time) T from when the vehicle starts in the first section (speed = 0 km / h) until it reaches a predetermined speed (target speed) V. Assuming that the vehicle travels with a travel pattern that changes in an S shape (so-called S-shaped acceleration / deceleration), the estimated fuel consumption per unit time when the vehicle travels with this speed change is calculated. The vehicle speed v is expressed by the following formulas (2) to (4) as the relationship between the speed v when the acceleration is changed by the acceleration change amount α per unit time and the travel time t from the start of the vehicle. .

v = α · t ² (0 ≦ t <T / 2) (2)

v = α · (T−t) ² + V (T / 2 ≦ t <T) (3)

  v = V (T ≦ t) (4)

The navigation apparatus 300 presets the target speed V and the target speed arrival time T, calculates the acceleration change amount α by the following equation (5) derived from v / 2 = α · (T / 2) ² , The vehicle speed v is calculated based on the equations (2) to (4), and the estimated fuel consumption is calculated and accumulated every time the vehicle speed v is calculated.

α = 2 · V / T ² (5)

  Specifically, as shown in FIG. 5, for example, the navigation device 300 is configured such that the vehicle speed v increases from the vehicle start to the travel time (= T / 2) that is half the target speed arrival time T ( 2) The vehicle speed v increases until it reaches half the target speed V (= 20 km / h) with a speed change that satisfies the expression (2) and then reaches the target speed arrival time T. An estimated fuel consumption amount of a vehicle that travels in a travel pattern that reaches a target speed V (= 40 km / h) with a satisfying speed change is calculated.

  Furthermore, the navigation device 300 maintains the vehicle speed v at the target speed V when the speed of the vehicle traveling in the acceleration pattern reaches a predetermined speed (the above equation (4)), and then the travel distance of the vehicle is The estimated fuel consumption per unit time of the vehicle is calculated until a predetermined distance is reached. Specifically, as shown in FIG. 5, the navigation apparatus 300 maintains the vehicle speed v at the target speed V (= 40 km / h) after the target speed arrival time T, and the travel distance of the vehicle is, for example, 200 m. Continue to calculate estimated fuel consumption until it reaches.

  The navigation device 300 increases or decreases the target speed arrival time T, and calculates the estimated fuel consumption amount of the vehicle traveling in the traveling pattern shown in FIG. Specifically, as shown in FIGS. 6-1 to 6-3, the navigation apparatus 300 calculates the total fuel consumption with a running pattern changed through the acceleration stage of the vehicle in the first section. Although illustration is omitted, the navigation device 300 corresponds to FIGS. 6-1 to 6-3, the travel time from the start of the vehicle, the vehicle speed v, the travel distance, and the total fuel consumption when the travel time has elapsed. Holds first to third tables composed of a plurality of records recorded in one record.

  Next, the navigation apparatus 300 refers to the total fuel consumption of the record in which the travel distance of the vehicle recorded in the first to third tables is 200 m, and is associated with the table that minimizes the total fuel consumption. The target speed arrival time T is acquired. Then, the navigation device 300 acquires the speed 5 seconds after the vehicle start in the table corresponding to the acquired target speed arrival time T as the vehicle speed threshold, and completes the acquisition process in the navigation device 300.

  Thereafter, the navigation device 300 notifies the user of the threshold value of the vehicle speed, as in the case of the outline of the acquisition process in the navigation device 300 and the first case.

(Acquisition process in the navigation apparatus 300, part 1)
As described above, the navigation device 300 calculates the estimated fuel consumption for each acceleration of the vehicle, acquires the threshold value of the vehicle speed, and notifies the user of it. Hereinafter, an outline of the acquisition process in the navigation apparatus 300 and details of the acquisition process shown in the first part will be described.

  In the description of the acquisition process, the acceleration, speed, and travel distance of the vehicle are set or calculated by the navigation device 300 in order to acquire the threshold value of the vehicle speed, not the acceleration, speed, and travel distance of the traveling vehicle. (Similarly, the acceleration, speed, and travel distance of the vehicle in the description of the acquisition process / part 2 in the navigation device 300 are also variables).

  FIG. 7 is a flowchart showing the procedure of the acquisition process by the navigation device. In the flowchart of FIG. 7, first, the navigation device 300 reads a range of acceleration (hereinafter simply referred to as “acceleration”) for acquiring a vehicle speed threshold value stored in advance in a storage device, for example. A value is set (step S701). In step S701, the navigation apparatus 300 sets, for example, the lower limit value of the acceleration range as the initial acceleration value.

  Next, the navigation apparatus 300 sets the vehicle speed for calculating the estimated fuel consumption (fuel consumption) to 0 km / h (step S702). The speed of the vehicle for calculating the fuel consumption is a variable set in advance when performing the acquisition process. Next, the navigation apparatus 300 calculates the speed of the vehicle (hereinafter simply referred to as speed) for calculating the fuel consumption based on the acceleration set in step S701 (step S703). Specifically, the acceleration set in step S701 is added to the current vehicle speed.

  Next, the navigation apparatus 300 determines whether or not the vehicle speed calculated in step S703 is greater than 40 km / h (step S704). In step S704, the speed of 40 km / h used as a criterion by the navigation device 300 is the speed of the vehicle maintained after the acceleration of the speed of the vehicle is completed. The criterion for determining the speed of the vehicle in step S704 is not limited to the speed of 40 km / h but can be variously changed depending on the type of the vehicle, for example.

  When the vehicle speed is 40 km / h or less (step S704: No), the navigation apparatus 300 proceeds to step S706. On the other hand, when the vehicle speed is higher than 40 km / h (step S704: Yes), the navigation device 300 sets the vehicle speed to 40 km / h (step S705). That is, the navigation device 300 maintains the vehicle speed at 40 km / h when the vehicle speed reaches 40 km / h.

  Next, the navigation apparatus 300 uses the above equation (1) based on the acceleration and speed set in steps S701 and S703, and the vehicle displacement, weight, vehicle height, vehicle width, and the like previously input by the user. Is used to calculate the fuel consumption (step S706). Next, the navigation apparatus 300 integrates the fuel consumption calculated in step S706 (step S707). In step S707, the navigation apparatus 300 calculates the total travel distance of the vehicle along with the total fuel consumption (total fuel consumption).

  Next, the navigation device 300 writes the speed calculated in step S703 and the total fuel consumption calculated in step S707, for example, in a storage device (step S708). In step S708, the navigation apparatus 300 may write out the total travel distance calculated in step S707.

  Next, the navigation apparatus 300 determines whether or not the total travel distance of the vehicle is greater than 200 m (step S709). In step S709, the total travel distance 200m used as a determination criterion by the navigation device 300 is a variable set in advance for performing the acquisition process. The criteria for determining the total mileage of the vehicle in step S709 can be variously changed depending on, for example, the type of vehicle.

  When the total travel distance of the vehicle is 200 m or less (step S709: No), the navigation apparatus 300 returns to step S703, and repeats the processing of steps S703 to S708 until it becomes step S709: Yes.

  On the other hand, when the total travel distance of the vehicle is greater than 200 m (step S709: Yes), the navigation device 300 writes the acceleration set in step S701, for example, in a storage device (step S710). The acceleration written to the storage device in step S710 is an acceleration for obtaining a threshold value of the vehicle speed. Next, the navigation apparatus 300 determines whether or not the acceleration used in steps S703 to S710 is greater than or equal to an upper limit value of a preset acceleration range (step S711).

  When the acceleration used in steps S703 to S710 is smaller than the upper limit value of the predetermined acceleration range (step S711: No), the navigation apparatus 300 increases the acceleration by a predetermined increment (step S712), and the process proceeds to step S702. Return. After that, the navigation device 300 repeats the processing of steps S702 to S710 until it becomes step S711: Yes. At this time, the acceleration used in steps S703, S706, and S710 is the acceleration set in step S712.

  Thus, for example, a table composed of a plurality of records in which information such as the travel time from the start of the vehicle, the speed of the vehicle when the travel time has elapsed, the travel distance, and the total fuel consumption is recorded in one record is displayed for each acceleration. And are stored in the storage device.

  On the other hand, when the acceleration used in steps S703 to S710 is equal to or greater than the upper limit value of the preset acceleration range (step S711: Yes), the navigation apparatus 300 reaches the vehicle travel distance stored in step S708 of 200 m. Of the total fuel consumption at that time, the acceleration associated with the minimum total fuel consumption is acquired (step S713).

  Next, the navigation device 300 reads the speed after 5 seconds from the start of the vehicle based on the acceleration acquired in step S713 (step S714), and ends the processing according to this flowchart. After that, the navigation device 300 notifies the user of the speed acquired in step S714 as a vehicle speed threshold.

  Further, the navigation device 300 may store only the total fuel consumption when the travel distance of the vehicle reaches 200 m after the process of step S709 without creating a table in the processes of steps S702 to S709. In this case, in step S713, the navigation device 300 selects the minimum total fuel consumption stored in the storage device, and acquires the acceleration associated with the selected total fuel consumption. And the navigation apparatus 300 calculates and acquires the speed | velocity | rate of the vehicle when predetermined time passes since the start when a vehicle accelerates with the acceleration acquired by step S713.

(Acquisition processing in the navigation apparatus 300, part 2)
Next, another example of the acquisition process in the navigation device 300 will be described in detail. The acquisition process described here is the acquisition process shown in the outline / part 2 of the acquisition process in the navigation device 300.

  FIG. 8 is a flowchart showing another procedure of acquisition processing by the navigation device. In the flowchart of FIG. 8, first, the navigation device 300 sets a target speed (step S801). In step S801, the navigation apparatus 300 may set the target speed to 40 km / h, for example.

  Next, for example, the navigation device 300 reads a range of the target speed arrival time stored in advance in the storage device, and sets an initial value of the target speed arrival time for acquiring a vehicle speed threshold value (step S802). In step S802, the navigation apparatus 300 sets, for example, the lower limit value of the target speed arrival time range as the initial value of the target speed arrival time.

  Next, the navigation apparatus 300 sets the vehicle speed for calculating the estimated fuel consumption (fuel consumption) to 0 km / h (step S803). In order to calculate the estimated fuel consumption, the speed of the vehicle is a variable set in advance when performing the acquisition process. Next, the navigation apparatus 300 obtains a vehicle speed threshold value (hereinafter simply referred to as acceleration) based on the target speed set in step S801 and the target speed arrival time set in step S802. Is calculated (step S804).

  Next, the navigation apparatus 300 calculates the speed of the vehicle (hereinafter simply referred to as speed) for calculating the fuel consumption based on the acceleration change amount and the travel time calculated in step S804 (step S805). . Specifically, the acceleration set in step S802 is added to the current vehicle speed.

  Next, the navigation apparatus 300 determines whether or not the vehicle speed calculated in step S805 is greater than 40 km / h (step S806). In step S806, the vehicle speed used as the determination criterion by the navigation device 300 is the same as the vehicle speed used in step S704, and is the vehicle speed that is maintained after the acceleration of the vehicle is completed.

  When the vehicle speed is 40 km / h or less (step S806: No), the navigation apparatus 300 proceeds to step S808. On the other hand, when the vehicle speed is higher than 40 km / h (step S806: Yes), the navigation device 300 sets the vehicle speed to 40 km / h (step S807). That is, the navigation device 300 maintains the vehicle speed at 40 km / h when the vehicle speed reaches 40 km / h.

  Next, the navigation device 300 uses the acceleration and speed set in steps S804 and S805, the displacement of the vehicle input in advance by the user, the weight, the vehicle height, the vehicle width, etc. The fuel consumption is calculated based on the equation (4) (step S808). Next, the navigation apparatus 300 integrates the fuel consumption calculated in step S808 (step S809). In step S809, the navigation apparatus 300 calculates the total travel distance of the vehicle along with the cumulative fuel consumption (total fuel consumption).

  Next, the navigation device 300 writes the speed calculated in step S805 and the total fuel consumption calculated in step S809, for example, in a storage device (step S810). In step S810, the navigation device 300 may also write the total travel distance calculated in step S809, for example, in a storage device.

  Next, the navigation apparatus 300 determines whether or not the total travel distance of the vehicle is greater than 200 m (step S811). In step S811, the total travel distance 200m used as the determination criterion by the navigation device 300 is the same as the total travel distance used as the determination criterion in the process of step S709, and is a variable set in advance when performing the acquisition process.

  When the total travel distance of the vehicle is 200 m or less (step S811: No), the navigation device 300 returns to step S804 and repeats the processes of steps S804 to S810 until it becomes step S811: Yes.

  On the other hand, when the total travel distance of the vehicle is greater than 200 m (step S811: Yes), the navigation device 300 writes the target speed arrival time set in step S802, for example, in a storage device (step S812). The target speed arrival time written in the storage device in step S812 is the target speed arrival time for acquiring the vehicle speed threshold. Next, the navigation apparatus 300 determines whether or not the target speed arrival time used in steps S804 to S812 is equal to or greater than an upper limit value of a preset acceleration range (step S813).

  When the target speed arrival time used in steps S804 to S812 is smaller than the preset upper limit of the target speed arrival time range (step S813: No), the navigation device 300 increases the target speed arrival time by a predetermined increment. (Step S814), the process returns to Step S803, and Steps S803 to S812 are repeated until Step S813: Yes. At this time, the target speed arrival time used in steps S804, S812, and S813 is the target speed arrival time set in step S814.

  Thus, for example, a table composed of a plurality of records in which information such as the travel time from the start of the vehicle, the speed of the vehicle when the travel time has elapsed, the travel distance, and the total fuel consumption is recorded in one record is the target speed. Created for each arrival time and stored in the storage device.

  When the target speed arrival time used in steps S803 to S810 is equal to or greater than the upper limit value of the target speed arrival time set in advance (step S813: Yes), the navigation device 300 stores the vehicle stored in step SS810. Of the total fuel consumption when the travel distance reaches 200 m, the target speed arrival time associated with the minimum total fuel consumption is acquired (step S815).

  Next, the navigation device 300 reads the speed after 5 seconds from the start of the vehicle based on the target speed arrival time acquired in step S815 (step S816), and ends the processing according to this flowchart. After that, the navigation device 300 notifies the user of the speed acquired in step S816 as a vehicle speed threshold.

  Further, the navigation device 300 may store only the total fuel consumption when the travel distance of the vehicle reaches 200 m after the process of step S811, without creating a table in the processes of steps S803 to S811. In this case, in step S815, the navigation device 300 selects the minimum total fuel consumption amount stored in the storage device, and acquires the target speed arrival time associated with the selected total fuel consumption amount. Then, the navigation device 300 calculates and acquires the speed when a predetermined time has elapsed from the start of the vehicle based on the target speed arrival time acquired in step S815.

  Thus, according to the navigation apparatus 300, the acceleration when the estimated fuel consumption is minimized is acquired, and the vehicle speed information that is the threshold value of the vehicle speed is acquired based on the acquired acceleration. The navigation device 300 calculates the estimated fuel consumption based on information that varies depending on the type of vehicle, such as the displacement of the vehicle, weight, vehicle height, and vehicle width. For this reason, the navigation device 300 acquires the vehicle speed threshold based on the acceleration when the total estimated fuel consumption of the vehicle is minimized, thereby saving the fuel consumption of the vehicle suitable for the type of vehicle. Can be provided to the user. Thereby, the user can obtain an effective operation method of the vehicle operated by the user.
