<< first embodiment >>
FIG. 1 is a diagram showing a configuration of a travel condition presentation system according to the present embodiment. As shown in FIG. 1, the travel condition presentation system according to the present embodiment includes a vehicle 100 provided with a power receiving device 120 capable of receiving power without contact, and power transmission capable of supplying power without contact. It is comprised from the non-contact charge driving path 200 which is a driving path with which the apparatus 210 was equipped. The vehicle 100 in the present embodiment may be an electric vehicle or a hybrid vehicle.

  First, the vehicle 100 will be described. As shown in FIG. 1, the vehicle 100 includes a control device 110, a power receiving device 120, a battery 130, and a display 140. The control device 110, the power receiving device 120, the battery 130, and the display 140 are connected by a CAN (Controller Area Network) or other in-vehicle LAN so that information can be exchanged between them.

  The vehicle 100 travels on the non-contact charging travel path 200, thereby receiving power from the non-contact charging travel path 200 and charging the battery 130. Specifically, as illustrated in FIG. 2, when the vehicle 100 travels on the non-contact charging travel path 200, the vehicle 100 receives power supplied from the power transmission device 210 provided on the non-contact charging travel path 200. 120 receives power. Then, the vehicle 100 charges the battery 130 by supplying the battery 130 with the power received by the power receiving device 120. Note that the power receiving device 120 and the power transmitting device 210 provided in the non-contact charging travel path 200 in the present embodiment are not particularly limited, and for example, a power receiving device that transmits and receives power by a method such as electromagnetic induction or magnetic resonance. And a power transmission device can be used.

  The control device 110 provided in the vehicle 100 includes, for example, a ROM that stores a program, a CPU that executes the program stored in the ROM, and a RAM that functions as an accessible storage device.

  Next, processing functions provided in the control device 110 will be described. The control device 110 calculates a necessary traveling condition when the vehicle 100 travels on the non-contact charging traveling path 200. The necessary traveling condition is a traveling condition that is required when the vehicle 100 travels on the non-contact charging traveling path 200 in order to satisfy the charging amount required for the battery 130.

  Control device 110 has a unit charge amount estimation function, a supplyable charge amount calculation function, a required SOC acquisition function, a required travel condition calculation function, and a presentation function in order to calculate such a required travel condition. The control device 110 can execute each function by cooperation of software for realizing the above functions and the hardware described above.

  Hereafter, each function which the control apparatus 110 mentioned above implement | achieves is each demonstrated.

  The unit charge amount estimation function provided in the control device 110 is a function that estimates a charge amount per unit time for the battery 130 when the vehicle 100 travels on the non-contact charging travel path 200. Here, FIG. 3 shows a scene where the vehicle 100 is traveling on the non-contact charging travel path 200 on the road surface on which the non-contact charging travel path 200 and the general travel path 300 are laid. The non-contact charging travel path 200 is a travel path including the power transmission device 210, and when the vehicle 100 travels on the non-contact charging travel path 200, the power transmission device 210 supplies power to the vehicle 100. This is a travel path capable of charging the battery 130 provided in the vehicle 100. The general travel path 300 is a normal travel path that does not include the power transmission device 210 and does not have a means for supplying power to the vehicle 100.

In the scene illustrated in FIG. 3, when the vehicle 100 starts traveling on the non-contact charging traveling path 200, the control device 110 estimates the amount of charge per unit time _{t_U} for the battery 130. Specifically, the control device 110 detects a charge amount charged in the battery 130 as a result of the vehicle 100 traveling on the non-contact charging travel path 200 for a predetermined time, and the vehicle 100 travels based on the detected charge amount. The charge amount per unit time _{t_U at} the speed that has been set is estimated as the unit time charge amount C _{t (X km / h)} . Note that _{(X km / h)} shown in the unit time charge amount C _{t (X km / h)} is the speed at which the vehicle 100 was traveling on the non-contact charging travel path 200. For example, in a scene where the amount of charge with respect to the battery 130 is detected as α kW when the vehicle 100 travels on the non-contact charging travel path 200 at 60 km / h for 5 minutes, the control device 110 sets the unit time _{t_U} to 1 minute. If set, the unit time charge amount C _{t (60 km / h)} , which is the charge amount per unit time _{t_U} when traveling at a speed of 60 km / h, is obtained by dividing αkw by 5 minutes. It is estimated to be 0.2αkw / min. The unit time _{t_U} is a value that is arbitrarily set for convenience in obtaining the unit time charge amount C _{t (X km / h)} , and can be set to, for example, 1 minute.

The supplyable charge amount calculation function provided in the control device 110 is a unit time charge amount C _{t (X km / h} ) when traveling at a speed X (unit: km / h) estimated by the unit charge amount estimation function described above. _The chargeable charge amount C _{pos (X km / h)} , which is the charge amount that can be supplied from the non-contact charging travel path 200 to the battery 130 per unit travel distance, is calculated. Note that _{(X km / h)} shown in the chargeable charge amount C _pos (X km / h) is similar to (X km / h) in the unit time charge amount C _{t (X km / h)} . It is the speed which was drive | working the non-contact charge drive path 200. Specifically, the control device 110 calculates the _supplyable charge amount C _{pos (X km / h) according} to the following equation (1) based on the unit time charge amount C _{t (X km / h)} .
C _{pos (X km / h)} = C _{t (X km / h)} / V (1)
In the above formula (1), V is the speed at which the vehicle 100 travels on the non-contact charging travel path 200, the speed used for calculating the unit time charge amount C _{pos (X km / h)} , and the unit time charge. The speed is the same as the speed used to calculate the quantity C _{t (X km / h)} . However, in the above formula (1), the unit of V is km / min. The unit of the unit time charge amount C _{t (X km / h)} is kw / min. Therefore, the unit of the chargeable charge amount C _{pos (X km / h)} obtained is kw / km.

For example, when the unit 100 charge amount Ct _{(60 km / h)} estimated by the unit charge amount estimation function is β kW / min when the vehicle 100 travels on the contactless charging travel path 200 at _{60 km / h} , 60 km / h, which is the speed of the vehicle 100, is 1 km / min when the unit is converted from the speed per hour to the speed per minute, so these values are applied to the above formula (1). The chargeable charge amount C _{pos (60 km / h)} can be expressed by the following formula (2).
C _{pos (60 km / h)} = β / 1 (2)
That is, according to the above equation (2), the chargeable charge amount C _{pos (60 km / h)} in this case is calculated as β kw / km.

  The required SOC acquisition function provided in control device 110 is a function for acquiring the required SOC obtained from the amount of charge required for battery 130. Specifically, control device 110 detects the current SOC from the current state of charge of battery 130, and in the state of charge when charging the amount of charge required for battery 130 based on the current SOC. A certain request SOC is acquired. Here, the amount of charge required can be arbitrarily set, for example, based on the amount of charge targeted by the user, the amount of charge required for the user to reach the destination with the vehicle 100, and the like. Can be set. In the case where the battery 130 is provided with a battery controller or the like, the control device 110 may acquire the request SOC obtained by the battery controller.

The required travel condition calculation function provided in the control device 110 is a function for calculating, as the required travel condition, a travel condition when the vehicle 100 travels on the non-contact charging travel path 200 necessary for satisfying the required SOC. Specifically, the control device 110 determines the required SOC when the vehicle 100 travels on the non-contact charging travel path 200 while maintaining the speed used for calculating the unit time charge amount C _{t (X km / h)} . Necessary travel distance D _nec necessary to satisfy the above condition is calculated, and a combination of the _speed and the necessary travel distance D _nec is calculated as a necessary travel condition. Here, the required travel distance D _nec is calculated according to the following formula (3) based on the chargeable charge amount C _{pos (X km / h)} .
D _nec = C _req / C _{pos (X km / h)} (3)
In the above formula (3), C _req is the amount of charge required to satisfy the required SOC. Further, in the above formula (3), the unit of C _req is kw, and the unit of the chargeable charge amount C _{pos (X km / h)} is kw / km. Therefore, the necessary travel distance D _nec is in units of km. As required.

For example, when a charge amount of 10 kw is necessary to satisfy the required SOC, vehicle 100 sets the required charge amount C _req as 10 kw. At this time, for example, when the chargeable charge amount C _{pos (60 km / h)} when traveling at a speed of 60 km / h is calculated as 1 kW / km, the required travel distance is calculated according to the above equation (3). D _nec is determined to be 10 km. Therefore, in this case, assuming that the speed used for calculating the unit time charge amount C _{t (X km / h) is} the planned travel speed V _keep , the planned travel speed V _keep is 60 km / h, and the control device 110 The necessary travel condition is calculated as a condition in which the planned travel speed V _keep and the necessary travel distance D _nec are combined, such as “speed 60 km / h, travel distance 10 km”.

The presentation function provided in the control device 110 is a function for presenting the necessary travel condition calculated by the necessary travel condition calculation function to the user via the display 140. Specifically, the control device 110 displays the calculated required travel condition on the display 140 as information on the planned travel speed V _keep and the required travel distance D _nec such as “speed 60 km / h, travel distance 10 km”. Thereby, the user can drive the vehicle 100 with reference to the information of the presented estimated traveling speed V _keep and the necessary traveling distance D _nec . Moreover, the control apparatus 110 is good also as guiding a required driving | running | working condition with respect to a user with an audio | voice not via the display 140 or with the display by the display 140.

FIG. 4 is a flowchart illustrating an example of a method for presenting a traveling condition to a user using the traveling condition presentation system in the present embodiment. In FIG. 4, when the vehicle 100 drive | works the non-contact charge driving | running route 200, the example which shows a driving condition to a user using the charging facility information provision system in this embodiment is shown.

  First, in step S <b> 101, the control device 110 determines whether or not the vehicle 100 has traveled on the non-contact charging travel path 200. For example, the control device 110 can detect that the power receiving device 120 has received a predetermined amount of power and can determine that the vehicle 100 has traveled on the non-contact charging travel path 200. When it is determined in step S101 that the vehicle 100 has traveled on the non-contact charging travel path 200, the process proceeds to step S102. On the other hand, if it is determined in step S101 that the vehicle 100 is not traveling on the non-contact charging travel path 200, the process stands by in step S101.

In step S102, the control device 110 estimates a unit time charge amount C _{t (X km / h)} that is a charge amount per unit time _{t_U} based on the result of the vehicle 100 traveling on the non-contact charging travel path 200. To do. Specifically, the control device 110 detects the amount of charge charged in the battery 130 as a result of the vehicle 100 traveling on the non-contact charging travel path 200 for a predetermined time, and unit time _{t_U} based on the detected amount of charge. The per-charge amount is estimated as the unit time charge amount C _{t (X km / h)} .

In step S103, the control device 110 supplies a charge amount that can be supplied from the non-contact charging travel path 200 to the battery 130 per unit travel distance based on the estimated unit time charge amount C _{t (X km / h).} The possible charge amount C _{pos (X km / h)} is calculated. Specifically, according to the above formula (1), the control device 110 sets the unit time charge amount C _{t (X km / h)} and the speed V at which the vehicle 100 was traveling on the non-contact charging travel path 200. Based on this, the chargeable charge amount C _{pos (X km / h)} is calculated.

  In step S <b> 104, control device 110 acquires a request SOC obtained from the amount of charge required for battery 130. Specifically, control device 110 detects the current SOC from the current state of charge of battery 130, and is the state of charge when the amount of charge required for battery 130 is charged based on the current SOC. Obtain the requested SOC. Or when the battery 130 is provided with the battery controller etc., the control apparatus 110 is good also as acquiring the request | requirement SOC which the battery controller calculated | required.

In step S <b> 105, control device 110 calculates a necessary traveling condition required when vehicle 100 travels on non-contact charging traveling path 200 that is necessary to satisfy the required SOC. Specifically, the control device 110 is based on the charge amount required to satisfy the requested SOC acquired in step S104 and the _suppliable charge amount C _{pos (X km / h)} calculated in step S103. , follow the above equation (3), by obtaining the required travel distance _{D nec,} calculates a planned travel speed _{V the keep,} the necessary driving conditions consisting of required travel distance _{D nec.} Here, the scheduled travel speed V _keep is the speed of the vehicle 100 when the unit time charge amount C _{t (X km / h)} is calculated in step S102.

In step S106, the control device 110 presents the necessary travel conditions calculated in step S105 to the user via the display 140 and voice. For example, the control device 110 displays the calculated required travel condition on the display 140 as information on the planned travel speed V _keep and the required travel distance D _nec such as “speed 60 km / h, travel distance 10 km”.

  In step S107, control device 110 determines whether or not the state of charge of battery 130 satisfies the required SOC. Specifically, control device 110 detects the current state of charge of battery 130 and determines whether the detected state of charge satisfies the required SOC. If it is determined in step S107 that the state of charge of the battery 130 satisfies the required SOC, the control device 110 executes a process for ending the travel condition presentation system, and ends this process. On the other hand, if it is determined in step S107 that the state of charge of the battery 130 does not satisfy the required SOC, the process proceeds to step S108.

In step S108, control device 110 determines whether or not charging of battery 130 proceeds as scheduled. This is because it is determined whether or not the battery 130 may not be charged as scheduled due to the vehicle 100 traveling in a position away from the power transmission device 210 provided in the non-contact charging travel path 200. To do. Here, as a method for determining whether or not the charging of the battery 130 is proceeding as planned, for example, the vehicle 100 is traveling on the non-contact charging travel path 200, and the actual amount of charge that has been charged. A method of comparing the charge amount with the expected charge amount estimated from the _supplyable charge amount C _{pos (X km / h)} calculated in S103 and determining whether or not the charge to the battery 130 is proceeding as planned. Can be mentioned. In this method, first, the control device 110 actually charges the battery 130 from the time when the charging state of the battery 130 is acquired in step S104 to the time when the current charging state of the battery 130 is acquired in step S107. The obtained charge amount is calculated as the actual charge amount. Further, the control device 110 calculates a predicted charge amount by multiplying the distance that the vehicle 100 actually travels on the non-contact charging travel path 200 and the chargeable charge amount C _{pos (X km / h)} calculated in step S103. Calculate as Then, the control device 110 calculates a difference between the calculated actual charge amount and the expected charge amount, and when the calculated difference is less than a predetermined threshold, charging the battery 130 is proceeding as scheduled. judge. The predetermined threshold value can be arbitrarily set in consideration of variations in the amount of charge when the vehicle 100 travels appropriately on the non-contact charging travel path 200. If it is determined in step S108 that charging of the battery 130 is proceeding as scheduled, the process returns to step S107. In the present embodiment, the process of step S108 is repeatedly executed at regular intervals until it is determined in step S107 that the required SOC is satisfied. On the other hand, if it is determined in step S108 that charging of the battery 130 has not proceeded as scheduled, the process proceeds to step S109.

  In step S109, the control device 110 notifies the user through the display 140 and voice that the necessary travel conditions are recalculated. Then, in step S109, after notifying the user that the required travel condition is to be recalculated, the process returns to step S102, and the process calculates the required travel condition for satisfying the requested SOC again based on the current SOC of the battery 130.

Specifically, the control device 410 provided in the information center 400 transmits a required travel condition transmission request and information on the request SOC, the vehicle type, and the current travel speed from the vehicle 100 via the communication device 420. It is determined whether or not it has been done. If it is determined in step S201 that the vehicle 100 has transmitted the required travel condition transmission request, the requested SOC, the vehicle type, and the current travel speed information, the process proceeds to step S202. On the other hand, if it is determined in step S201 that the required travel condition transmission request and information on the requested SOC, the vehicle type, and the current travel speed are not transmitted from the vehicle 100, the process waits in step S201.

  In step S201, if it is determined that the required travel condition transmission request and the requested SOC, vehicle type, and current travel speed information are transmitted from the vehicle 100, the process proceeds to step S202. In step S202, the information center 400 Then, it is determined whether or not the speed of traveling on the non-contact charging travel path 200 is regulated. Specifically, the control device 410 provided in the information center 400 sets a predetermined lower limit speed or the like on the non-contact charging travel path 200 on which the vehicle 100 is about to travel, and the speed at which the vehicle 100 travels. Whether or not is regulated. The predetermined lower limit speed is a lower limit value of the speed limit set in the non-contact charging travel path 200 for the purpose of not disturbing the traffic flow of other vehicles, and can be set to, for example, about 30 km / h. . And when it determines with the speed which drive | works the non-contact charge driving | running route 200 in step S202 being controlled, it progresses to step S210. On the other hand, when it determines with the speed which drive | works the non-contact charge driving | running route 200 in step S202 being not controlled, it progresses to step S203.

  If it is determined in step S202 that the speed at which the vehicle 100 travels is not regulated, the process proceeds to step S203. In step S203, the information center 400 determines whether the travel route of the vehicle 100 is set by the user. Determine whether. For example, the control device 410 provided in the information center 400 receives information on the travel route set for the vehicle 100 to arrive at a specific destination from the vehicle 100 via the communication device 420. Then, it is determined whether or not the travel route of the vehicle 100 is set by the user. If it is determined in step S203 that the travel route of the vehicle 100 has been set by the user, the process proceeds to step S215. On the other hand, when it is determined in step S202 that the travel route of the vehicle 100 is not set by the user, the process proceeds to step S204.

If it is determined in step S203 that the travel route of the vehicle 100 has not been set by the user, the process proceeds to step S204. In step S204, the information center 400 has no restriction on the speed at which the vehicle 100 travels and travels. When the route is not set, a necessary traveling condition when the vehicle 100 travels on the non-contact charging traveling path 200 that is about to travel is calculated. Specifically, first, when the current travel speed of the vehicle 100 is X km / h, the control device 410 travels at a speed of X km / h on the non-contact charging travel path 200 that the vehicle 100 is about to travel. The information on the chargeable charge amount C _{pos (X km / h)} is extracted from the database 430. As described above, the database 430 stores information on the chargeable charge amount C _{pos (X km / h)} for each vehicle type of the vehicle 100, the speed of the vehicle 100, and the non-contact charging travel path 200. For this reason, the control device 410 uses the vehicle 100 of the same vehicle type as the vehicle 100 on the non-contact charging travel path 200 that the vehicle 100 is about to travel for the vehicle 100 to which the required travel condition transmission request is transmitted. Information on the chargeable charge amount C _{pos (X km / h)} when traveling at h can be extracted from the database 430.
Then, the control device 410, based on the extracted chargeable charge amount C _{pos (X km / h)} , according to the above formula (3), the required travel distance D _nec for satisfying the requested SOC transmitted from the vehicle 100. To calculate the necessary driving conditions.

In step S205, the information center 400 determines whether or not the requested SOC can be satisfied by traveling the non-contact charging traveling path 200 that the vehicle 100 is about to travel. For example, in the control device 410 provided in the information center 400, the non-contact charging travel path 200 on which the vehicle 100 is about to travel is closed due to a traffic accident, road construction, bad weather, or maintenance of the travel path. If the vehicle 100 cannot travel on the non-contact charging travel path 200 having the required travel distance D _nec obtained in step S204, it is determined that the required SOC cannot be satisfied. If it is determined in step S205 that the required SOC can be satisfied, the process proceeds to step S206. On the other hand, if it is determined in step S205 that the requested SOC cannot be satisfied, the process proceeds to step S208.

  If it is determined in step S205 that the required SOC can be satisfied, the process proceeds to step S206. In step S206, the information center 400 transmits the calculated necessary travel condition to the vehicle 100. Specifically, the control device 410 provided in the information center 400 transmits the required travel condition calculated in step S <b> 204 to the communication device 150 provided in the vehicle 100 via the communication device 420.

In step S207, the vehicle 100 presents necessary travel conditions to the user. Specifically, the control device 110 provided in the vehicle 100 presents information on the scheduled traveling speed V _keep and the necessary traveling distance D _nec as necessary traveling conditions to the user via the display 140.

On the other hand, if it is determined in step S202 that the speed at which the vehicle 100 travels is restricted, the process proceeds to step S210. In step S210, the information center 400 sets the travel route of the vehicle 100 by the user. It is determined whether or not. If it is determined in step S210 that the travel route of the vehicle 100 has been set by the user, the process proceeds to step S213. In step S213 and subsequent steps, can the information center 400 travel the required travel distance D _nec to satisfy the required SOC by traveling on the non-contact charging travel path 200 on the travel route on which the vehicle 100 is set? Determine whether or not. When the In set travel route can not travel required travel distance D _nec to meet the requirements SOC, the information center 400, the vehicle runs the required travel distance D _nec to meet the requirements SOC Reset the possible travel routes. On the other hand, if it is determined in step S210 that the travel route is not set by the user, the process proceeds to step S211. After step S211, the information center 400 determines whether or not the vehicle 100 can travel the required travel distance D _nec to satisfy the required SOC by traveling on the non-contact charging travel path 200 that the vehicle 100 is about to travel. judge. If the required travel distance D _nec cannot be satisfied on the non-contact charging travel path 200 on which the vehicle 100 is about to travel, the information center 400 travels the required travel distance D _nec to satisfy the required SOC. Set a travel route that can be used.

If it is determined in step S210 that the travel route of the vehicle 100 is set by the user, the process proceeds to step S213, and in step S213, the information center 400 is in a non-contact state that exists on the set travel route. Necessary travel conditions when the vehicle 100 travels on the charging travel path 200 at a regulated speed are calculated. Specifically, the control device 410 provided in the information center 400 first supplies chargeable power when traveling on the non-contact charging travel path 200 existing on the set travel route at a regulated speed. Information on the quantity C _{pos (X km / h)} is extracted from the database 430. Then, the control device 410, based on the extracted chargeable charge amount C _{pos (X km / h)} , according to the above formula (3), the required travel distance D _nec for satisfying the requested SOC transmitted from the vehicle 100. To calculate the necessary driving conditions.

In step S214, the information center 400 determines whether or not the required SOC can be satisfied when the vehicle 100 travels at the regulated speed on the non-contact charging travel path 200 existing on the set travel route. judge. For example, in the control device 410 provided in the information center 400, the distance of the non-contact charging travel path 200 existing on the set travel route is longer than the required travel distance D _nec calculated in step S213 by a certain distance or more. In this case, since vehicle 100 can travel on non-contact charging travel path 200 with a sufficient distance to charge battery 130, it is determined that the required SOC can be satisfied. If it is determined in step S214 that the required SOC can be satisfied, the process proceeds to step S206. In steps S206 and S207 described above, the necessary travel conditions calculated in step S213 are transmitted to the vehicle 100 and presented to the user. On the other hand, if it is determined in step S214 that the requested SOC cannot be satisfied, the process proceeds to step S208.

If it is determined in step S214 that the requested SOC cannot be satisfied, the process proceeds to step S208. In step S208, the information center 400 extracts a travel route that can satisfy the requested SOC. Specifically, the control device 410 provided in the information center 400 transmits a required travel condition transmission request based on the map data information stored in the database 430 and the non-contact charging travel route 200 information. At least one travel route that passes through the non-contact charging travel route 200 existing within a predetermined distance from the vehicle 100 is extracted. Then, the control device 410 causes the vehicle 100 to travel on the non-contact charging travel path 200 existing on the travel route at the current travel speed from the extracted travel routes, so that the necessary travel distance D _nec that satisfies the required SOC is satisfied. The travel route expected to be able to travel is extracted.

In step S209, the information center 400 calculates a required travel condition when the vehicle 100 travels on the non-contact charging travel path 200 existing on the travel route extracted in step S208. Specifically, first, when the current travel speed of the vehicle 100 is X km / h, the control device 410 provided in the information center 400 determines that the non-contact charging travel path exists on the extracted travel route. Information on the chargeable charge amount C _{pos (X km / h)} when driving 200 at _{X km / h is} extracted from the database 430. Then, the control device 410, based on the extracted chargeable charge amount C _{pos (X km / h)} , according to the above formula (3), the required travel distance D _nec for satisfying the requested SOC transmitted from the vehicle 100. To calculate the necessary driving conditions. After the required travel conditions are calculated in step S209, the required travel conditions calculated in step S209 are transmitted to the vehicle 100 in steps S206 and S207 described above and presented to the user. At this time, the travel route information extracted in step S208 is transmitted to the vehicle 100 together with the necessary travel condition calculated in step S209 and presented to the user.

On the other hand, if it is determined in step S210 that the travel route is not set by the user, the process proceeds to step S211. In step S211, the information center 400 causes the non-contact charging travel path 200 on which the vehicle 100 is about to travel. The necessary traveling conditions when traveling at a regulated speed are calculated. Specifically, the control device 410 provided in the information center 400 first supplies the charge amount C _{pos that} can be supplied when the vehicle 100 travels at a regulated speed on the non-contact charging travel path 200 that the vehicle 100 intends to travel. Information of _{(X km / h)} is extracted from the database 430. Then, the control device 410, based on the extracted chargeable charge amount C _{pos (X km / h)} , according to the above formula (3), the required travel distance D _nec for satisfying the requested SOC transmitted from the vehicle 100. To calculate the necessary driving conditions.

In step S212, the information center 400 determines whether or not the required SOC can be satisfied when the vehicle 100 travels at the regulated speed on the non-contact charging travel path 200 that the vehicle 100 is about to travel. Specifically, the control device 410 provided in the information center 400 is such that the distance of the non-contact charging travel path 200 on which the vehicle 100 is about to travel is longer than the required travel distance D _nec calculated in step S211 by a certain distance or more. In this case, since vehicle 100 can travel on non-contact charging traveling path 200 with a sufficient distance to charge battery 130, it is determined that the required SOC can be satisfied. If it is determined in step S212 that the required SOC can be satisfied, the process proceeds to step S206. In steps S206 and S207 described above, the required travel conditions calculated in step S211 are transmitted to the vehicle 100 and presented to the user. On the other hand, if it is determined in step S212 that the requested SOC cannot be satisfied, the process proceeds to step S208. In steps S208 and S209 described above, a new travel route is extracted, and a necessary travel condition when the vehicle 100 travels on the non-contact charging travel route 200 existing on the extracted travel route is calculated.

On the other hand, when it is determined in step S203 that the travel route has been set by the user, the process proceeds to step S215, and in step S215, the information center 400 is in contactless charging existing on the set travel route. Necessary travel conditions when the vehicle 100 travels on the travel path 200 are calculated. Specifically, first, when the current traveling speed of the vehicle 100 is X km / h, the control device 410 provided in the information center 400 performs non-contact charging that exists on the set traveling route. Information on the chargeable charge amount C _{pos (X km / h)} when traveling on the travel path 200 at _{X km / h is} extracted from the database 430. Then, the control device 410, based on the extracted chargeable charge amount C _{pos (X km / h)} , according to the above formula (3), the required travel distance D _nec for satisfying the requested SOC transmitted from the vehicle 100. To calculate the necessary driving conditions.

In step S216, the information center 400 determines whether or not the required SOC can be satisfied by the vehicle 100 traveling on the non-contact charging travel path 200 existing on the set travel route. For example, the control device 410 provided in the information center 400 allows the non-contact charging travel path 200 existing on the set travel route to be used for a traffic accident, road construction, bad weather, or maintenance of the travel path. If the vehicle 100 is closed and the vehicle 100 cannot travel on the non-contact charging travel path 200 having the required travel distance D _nec obtained in step S215, it is determined that the required SOC cannot be satisfied. If it is determined in step S216 that the required SOC can be satisfied, the process proceeds to step S206. In steps S206 and S207 described above, the required travel condition calculated in step S215 is transmitted to the vehicle 100 and presented to the user. On the other hand, if it is determined in step S216 that the required SOC cannot be satisfied, the process proceeds to step S208. In steps S208 and S209 described above, a new travel route is extracted, and a necessary travel condition when the vehicle 100 travels on the non-contact charging travel route 200 existing on the extracted travel route is calculated.

According to 2nd Embodiment, in addition to the effect by 1st Embodiment mentioned above, there exist the following effects.
That is, in the second embodiment, when the vehicle 100 needs to travel on the contactless charging travel path 200 at a regulated speed, the information center 400 moves the contactless charging travel path 200 at a regulated speed. The required travel distance D _nec when traveling is calculated, and the calculated required travel distance D _nec is presented to the user as a required travel condition. As a result, even when the speed at which the vehicle 100 travels is regulated in the non-contact charging travel path 200 on which the vehicle 100 is about to travel, the user can follow the specific travel conditions indicated by the user's own vehicle. Thus, by traveling on the non-contact charging traveling path 200, charging can be appropriately completed without excessive or insufficient power supply.

  In the second embodiment, the following effects are further obtained. That is, when the travel center of the vehicle 100 is set and the information center 400 determines that the required SOC cannot be satisfied because the vehicle 100 travels along the travel route, the information center 400 sets the required SOC. A new travel route in which the non-contact charging travel route 200 exists for a distance necessary to satisfy is reset, and information on the reset travel route and the non-contact charging travel route 200 existing on the reset travel route are set. Information on the required travel conditions when traveling is presented to the user. Thus, even when the user cannot charge the required amount of charge on the preset travel route, the user can perform non-contact charging travel on his / her vehicle according to the new travel route and necessary travel conditions that are specifically shown. By traveling on the road 200, charging can be appropriately completed without excess or deficiency of power supply.

  In the above-described embodiment, the control device 110 provided in the vehicle 100 includes the unit charge amount estimation unit, the supplyable charge amount calculation unit, the required SOC acquisition unit, the required travel condition calculation unit, and the presentation unit of the present invention. In addition, the control device 410 provided in the information center 400 includes a unit charge amount estimation unit, a supplyable charge amount calculation unit, a required SOC acquisition unit, a required travel condition calculation unit, a presentation unit, a determination unit, and a travel according to the present invention. These correspond to route resetting means.

  As mentioned above, although embodiment of this invention was described, these embodiment was described in order to make an understanding of this invention easy, and was not described in order to limit this invention. Therefore, each element disclosed in the above embodiment is intended to include all design changes and equivalents belonging to the technical scope of the present invention.

  For example, in the first embodiment described above, the control device 110 provided in the vehicle 100 is similar to the second embodiment described above in cases where the travel speed of the vehicle 100 is restricted or the travel route of the vehicle 100 is In the case where it is set in advance, a configuration may be adopted in which the necessary travel conditions are calculated in consideration of these situations.

That is, when the traveling speed of the vehicle 100 is regulated, the control device 110 calculates a necessary traveling condition when the vehicle 100 travels at the regulated speed. Specifically, first, the control device 110 calculates a chargeable charge amount C _{pos (X km / h)} when traveling at a regulated speed. And the control apparatus 110 calculates | requires the required traveling distance D _nec for satisfy | filling request | requirement SOC according to the said Formula (3) based on the calculated chargeable charge amount C _{pos (X km / h)} , Calculate the required driving conditions. The calculated required travel distance D _nec is presented to the user via the display 140 as a required travel condition. As a result, even when the speed at which the vehicle 100 travels is regulated in the non-contact charging travel path 200 on which the vehicle 100 is about to travel, the user can follow the specific travel conditions indicated by the user's own vehicle. Thus, by traveling on the non-contact charging traveling path 200, charging can be appropriately completed without excessive or insufficient power supply.

When the travel route of vehicle 100 is set in advance, control device 110 determines whether or not the requested SOC can be satisfied with the currently set travel route, and satisfies the required SOC. If it is determined that this is not possible, a new travel route is set. Specifically, first, control device 110 determines that the requested SOC cannot be satisfied when it receives information that non-contact charging travel path 200 on which vehicle 100 is about to travel is closed. . When the vehicle 100 is provided with a database storing map data, or when the map data can be received from the information center 400 or the like, the control device 110 makes a request based on the map data. A new travel route in which the non-contact charging travel path 200 expected to be able to travel the required travel distance D _nec that satisfies the SOC is extracted. Further, when the control device 110 acquires information such as the type, the number of installed power transmissions, the installation interval, and the power transmission output of the power transmission device 210 provided in the contactless charging travel route 200 existing on the extracted new travel route. Calculates the necessary travel conditions when traveling on the extracted new travel route based on the acquired information. Then, the extracted new travel route and the necessary travel conditions for the new travel route are presented to the user via the display 140. Thus, even when the user cannot charge the required amount of charge on the preset travel route, the user can perform non-contact charging travel on his / her vehicle according to the new travel route and necessary travel conditions that are specifically shown. By traveling on the road 200, charging can be appropriately completed without excess or deficiency of power supply.

In the first embodiment described above, the control device 110 provided in the vehicle 100 is not in contact with the vehicle 100 due to traffic jams or the need to rush to the destination in the scene shown in FIG. When the speed is changed by accelerating or decelerating while traveling on the charging travel path 200, a plurality of unit time charging amounts C _{t (X km / h)} are estimated according to the speed at which the vehicle 100 travels. It is good also as such a structure. For example, when the vehicle 100 travels for 60 hours at 60 km / h for a certain time and then the vehicle 100 travels for 40 hours at 40 km / h for a certain time after the vehicle 100 has traveled for a certain time at 40 km / h. The controller 110 distinguishes and detects the charge amount obtained as a result of traveling at 60 km / h and the charge amount obtained as a result of traveling at 40 km / h, respectively. Then, control device 110 obtains unit time charge amount C _{t (X km / h)} at the speed at which vehicle 100 travels based on the detected charge amount. That is, from the amount of charge obtained as a result of traveling at 60 km / h, the unit time charge amount C _{t (60 km / h)} when traveling at a speed of 60 _{km / h} is estimated, and the result of traveling at 40 km / h As a result, the unit time charge amount _{Ct (40 km / h)} when traveling at a speed of 40 _{km / h} is estimated.

And the control apparatus 110 with which the vehicle 100 is equipped is based on the estimated unit time charge amount _{Ct (X km / h)} , and several chargeable charge amount _{Cpos which} can be supplied according to the speed which the vehicle 100 drive _{| worked. (X km / h)} is calculated. The relationship between the chargeable charge amount C _{pos (X km / h)} at the speed _{X km / h} and the chargeable charge amount C _{pos (Y km / h)} at the _{speed Y km / h} is expressed by the following formula (4). The
C _{pos (Y km / h)} = (X / Y) × C _{pos (X km / h)} (4)
This is because the time during which the vehicle 100 passes through the power transmission device 210 provided in the non-contact charging travel path 200 is shortened in inverse proportion to the speed of the vehicle 100, so that the vehicle 100 is supplied from the non-contact charging travel path 200. This is because the electric power per unit travel distance decreases similarly in inverse proportion to the speed of the vehicle 100. For example, the relationship between the chargeable charge amount C _{pos (60 km / h)} when traveling at a speed of 60 _{km / h} and the chargeable charge amount C _{pos (40 km / h)} when traveling at a speed of 40 km / h is as described above. According to the equation (4), C _{pos (60 km / h)} = (40/60) × C _{pos (40 km / h)} .

Further, when the control device 110 provided in the vehicle 100 calculates a plurality of chargeable charge amounts C _{pos (X km / h)} as described above, the control device 110 determines that the necessary speed V _nec is A plurality of necessary travel conditions obtained by changing the above-described necessary travel distance D _nec are calculated. Here, the required speed V _nec is a speed required when the vehicle 100 travels on the non-contact charging travel path 200 in order to satisfy the required SOC regardless of the speed at which the vehicle 100 is currently traveling, and is a unit time. This is the speed used for calculating the charge amount C _{t (X km / h)} . For example, when the controller 110 calculates the chargeable charge amount C _{pos (60 km / h)} when traveling at a speed of 60 km / h, the required speed V _{nec is set} to 60 km / h, and the above equation (3) Accordingly, if the calculated required travel distance D _nec is x km, the required travel condition is “speed 60 km / h, travel distance x km”. In addition, when the controller 110 calculates the chargeable charge amount C _{pos (40 km / h)} when traveling at a speed of 40 km / h, the required speed V _{nec is set} to 40 km / h, and the above equation (3) is satisfied. Accordingly, if the calculated required travel distance D _nec is y km, the required travel condition is “speed 40 km / h, travel distance y km”.

Also in the second embodiment described above, a plurality of required traveling conditions may be calculated and presented to the user as in the first embodiment described above. Specifically, first, control device 410 provided in information center 400 receives information on the requested SOC of vehicle 100 and vehicle type information from vehicle 100 together with a request for transmitting a required traveling condition. Then, based on the received information, the control device 410 determines that the vehicle 100 of the same vehicle type as the vehicle 100 to which the required travel condition transmission request is transmitted is the vehicle 100 to which the required travel condition transmission request is transmitted. The chargeable charge amount C _{pos (X km / h)} when it is assumed that the contact charging travel path 200 traveled at various speeds is extracted from the database 430. As described above, the database 430 stores the vehicle type of the vehicle 100, the speed of the vehicle 100, and the charge amount C _{pos (X km / h)} that can be supplied for each non-contact charging travel path 200. Then, the control device 410 calculates a plurality of necessary traveling conditions obtained by changing the necessary speed V _nec and the necessary traveling distance D _nec based on the extracted chargeable charge amount C _{pos (X km / h)} . For example, the control device 410 extracts the chargeable charge amount C _{pos (60 km / h)} when traveling at a speed of 60 km / h, sets the necessary speed V _nec to 60 km / h, and calculates it according to the above equation (3). When the required travel distance D _nec is x km, the required travel condition is calculated as “speed 60 km / h, travel distance x km”. Further, the control device 410 extracts the chargeable charge amount C _{pos (40 km / h)} when the vehicle travels at a speed of 40 km / h, sets the required speed V _nec to 40 km / h, and calculates it according to the above equation (3). When the required travel distance D _nec is y km, the required travel condition is calculated as “speed 40 km / h, travel distance y km”.

In the present embodiment, as the required travel condition, the required speed V _nec that is a speed required when the vehicle 100 travels the non-contact charging travel path 200 in order to satisfy the required SOC, and the vehicle 100 is the non-contact charging travel path. Information including the required travel distance D _nec that is a distance for traveling 200 is provided to the user. Accordingly, the user can appropriately complete the charging without excessive or insufficient power feeding by traveling on the non-contact charging traveling path 200 with the own vehicle according to the necessary traveling conditions specifically shown.

Further, in the present embodiment, by calculating a plurality of necessary traveling conditions obtained by changing the necessary speed V _nec and the necessary traveling distance D _nec , the plurality of calculated necessary traveling conditions can be presented to the user. . Thereby, the user can select arbitrary required driving conditions from a plurality of the required driving conditions presented.

At this time, when the travel route of the vehicle 100 is set by the user, the necessary speed V _nec when the vehicle 100 travels on the non-contact charging travel path 200 existing on the set travel route and The necessary travel condition consisting of the necessary travel distance D _nec is calculated. Therefore, when the travel route of the vehicle 100 is set by the user, it is possible to provide the user with information on the necessary speed V _nec when traveling on the set travel route. As a result, when the user travels on a preset travel route, the user can appropriately charge the vehicle without running out of power supply by traveling on the travel route in accordance with the required travel conditions. Can be completed.

Further, in the present embodiment, instead of estimating a unit time charge amount C _{t (X km / h)} that is a charge amount per unit time _{t_U} when the vehicle 100 travels on the non-contact charging travel path 200. The unit distance charge amount C _{d (X km / h)} that is the charge amount per unit distance may be estimated. Note that _{(X km / h)} shown in the unit distance charge amount C _{d (X km / h)} is the speed at which the vehicle 100 was traveling on the non-contact charging travel path 200. The unit distance is a value that is arbitrarily set for convenience when obtaining the charge amount per distance, and is set to 1 km, for example.

When the unit distance charge amount C _{d (X km / h)} is estimated instead of the unit time charge amount C _{t (X km / h)} , the estimated unit distance charge amount C _{d (X km) / H) is} the value of the chargeable charge amount C _{pos (X km / h)} . That is, when the unit distance charge amount Cd _{(X km / h)} is estimated to be γkw / km, the supplyable charge amount C _{pos (X km / h)} is γkw / km.
