[Technical field]

[0001] The present disclosure relates to a driving route presentation system, a vehicle, a server, and a method for presenting a driving route, and more particularly to a method for presenting a driving route for a vehicle capable of contactless charging using external power. [Background technology]

[0002] In recent years, attention has been focused on non-contact charging roads, in which power transmission devices are installed on the roads and power can be supplied contactlessly to vehicles that are moving or stopped at traffic lights. JP 2013-200247 A (Patent Document 1) discloses a navigation device that can perform route searches using information about non-contact charging roads. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2013-200247 A Summary of the Invention [Problem to be solved by the invention]

[0004] In general, when a vehicle is heavily loaded, more drive energy is required to run than when the vehicle is lightly loaded. Therefore, in an electrically powered vehicle such as a hybrid vehicle or an electric vehicle that can run using power from a battery mounted on the vehicle, when the vehicle is heavily loaded, there is a possibility that the vehicle will run out of power before reaching the destination, or that the vehicle will not have enough power remaining when the vehicle arrives at the destination.

[0005] The navigation device of the above-mentioned Patent Document 1 uses information on non-contact charging roads to search for a route, allowing the user to select a driving route that suits their purpose. However, Patent Document 1 does not take into consideration the decrease in energy efficiency (i.e., decrease in electricity cost) that accompanies changes in the vehicle's load. Therefore, even if the user selects the presented driving route, there is a possibility that the appropriate amount of charge will not be secured.

[0006] The present disclosure has been made to solve such problems, and its purpose is to ensure that a vehicle capable of contactless charging has enough charge to reach its destination even when it is heavily loaded. [Means for solving the problem]

The vehicle includes a battery that can be charged by power supplied from an external source, a detection device for detecting information about a load on the vehicle, and a power receiving device that can receive power in a non-contact manner from a power transmitting device provided on the driving route to the destination. The server i) acquires information about the load from the vehicle, ii) searches for candidates for driving routes to the set destination, iii) acquires information about the power transmitting devices arranged on the searched candidates for the driving route, and iv) presents to the vehicle 100 a driving route in which the power transmitting device can be used with a higher priority when the load is large than when the load is small.

[0008] A vehicle according to a second aspect of the present disclosure includes a battery, a detection device, a power receiving device, and a control device. The battery is configured to be chargeable by power supplied from an external source. The detection device detects information related to a load amount. The power receiving device is configured to be able to receive power from the power transmitting device in a non-contact manner. The control device presents a driving route to a destination to a user. The control device i) acquires information related to the load amount from the detection device, ii) acquires candidate information of driving routes to the destination set by the user, iii) acquires information on a power transmitting device disposed on the driving route included in the candidate information, and iv) when the load amount is large, presents a driving route in which the power transmitting device can be used with a higher priority than when the load amount is small.

[0009] A server according to a third aspect of the present disclosure is configured to be able to communicate with a vehicle and includes a processor and a storage device in which map information and power transmission device information are stored. The vehicle includes a power receiving device capable of receiving power contactlessly from an external power transmitting device, and a battery capable of being charged using the power received by the power receiving device. The processor i) acquires vehicle information including information on a destination and a load from the vehicle, ii) searches for candidates for a driving route to the destination using map information based on the vehicle information, iii) acquires information on a power transmission device disposed on the searched candidates for the driving route based on the power transmission device information, and iv) presents to the vehicle a driving route in which the power transmission device can be used with a higher priority when the load is large than when the load is small.

[0010] A method according to a fourth aspect of the present disclosure relates to a method for presenting a driving route to a destination to a vehicle. The vehicle includes a power receiving device capable of receiving power contactlessly from a power transmitting device provided outside the vehicle, and a battery capable of being charged by the received power. The method includes steps of: i) acquiring information about a payload of the vehicle; ii) searching for a driving route to the destination; iii) acquiring information about a power transmitting device disposed on the searched driving route; and iv) presenting a driving route in which the power transmitting device can be used with a higher priority when the payload is large than when the payload is small. Effect of the Invention

[0013] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference characters and their description will not be repeated.

[0014] [System Overview] Fig. 1 is a schematic diagram of a driving route presentation system 10 according to the present embodiment. Referring to Fig. 1, the system 10 includes a vehicle 100 and a server 300. The vehicle 100 and the server 300 are configured to be able to communicate with each other via a communication network 400 such as the Internet. The communication between the vehicle 100 and the communication network 400 is performed wirelessly. The communication between the server 300 and the communication network 400 may be wired or wireless.

[0015] Vehicle 100 is configured to be able to receive electric power in a contactless manner from power transmitting device 200 disposed externally.

[0016] When the server 300 receives destination information from the vehicle 100, the server 300 uses map information to search for a driving route from the current position of the vehicle 100 to the destination, and transmits the route information to the vehicle 100. In the vehicle 100, one of the driving routes presented by the server 300 is selected by the user. As the vehicle 100 travels, the server 300 provides guidance on the driving route selected by the user.

[0017] The server 300 includes a processor 310, a storage device 305, and a communication device 350. The storage device 305 includes a memory 320, a map database (DB) 330, and a power transmitting device database 340. The processor 310, the memory 320, the map database 330, the power transmitting device database 340, and the communication device 350 are connected to each other by a common bus 360, and are configured to be able to send and receive information to and from each other.

[0018] The processor 310 is, for example, a CPU (Central Processing Unit) and is configured to execute a predetermined arithmetic processing described in a program. The memory 320 includes a ROM (Read Only Memory) and a RAM (Random Access Memory). The ROM stores the program executed by the processor 310. The RAM temporarily stores data generated by the execution of the program in the processor 310 and data input via the communication device 350. The RAM also functions as a temporary data memory used as a working area.

[0019] The communication device 350 is a communication interface for transmitting and receiving data to and from the vehicle 100 via the communication network 400. As described above, communication between the server 300 and the communication network 400 is performed by wire or wirelessly.

[0020] Map database 330 stores map information including road information. When processor 310 receives information on the current position and destination transmitted from vehicle 100, processor 310 refers to the map information included in map database 330 and searches for candidates for a driving route from the current position to the destination.

[0021] The power transmission device database 340 stores information about the power transmission devices 200 arranged on roads. The information about the power transmission devices 200 includes position information and specification information about the power transmission devices 200. In searching for candidates for the travel route described above, the processor 310 acquires the power transmission devices 200 arranged on each travel route from the power transmission device database 340. As will be described later, the processor 310 determines the priority order of candidates for the travel route to be presented to the user, taking into consideration information about the state of charge of the battery mounted on the vehicle 100 and information about the load capacity.

[0022] [Vehicle and power transmission device configuration] Next, detailed configurations of vehicle 100 and power transmitting device 200 will be described with reference to Fig. 2. First, the configuration of vehicle 100 will be described with reference to Fig. 2. Vehicle 100 includes ECU (Electronic Control unit) 110, which is a control device, communication device 120, navigation device 125, power receiving coil 130, charging device 140, power storage device (battery) 145, PCU (Power Control Unit) 160, which is a drive device, motor generator (MG) 165, camera 170, RFID (Radio Frequency Identifier) ​​reader 175, and detection device 180.

[0023] The power receiving coil 130 is disposed on the lower surface of a floor panel that forms the bottom surface of the vehicle 100. The power receiving coil 130 receives the power transmitted from the power transmitting device 200 in a non-contact manner. The power received by the power receiving coil 130 is output to the charging device 140.

[0024] The charging device 140 includes, for example, an AC / DC converter or a rectifier. The charging device 140 is controlled by the ECU 110, and converts the AC power received by the power receiving coil 130 into DC power suitable for charging the battery 145, to charge the battery 145. The battery 145 is an assembled battery including a plurality of cells, and each cell included in the battery 145 is a secondary battery such as a lithium ion battery or a nickel metal hydride battery.

[0025] The PCU 160 includes, for example, a DC / DC converter and an inverter. The PCU 160 converts DC power from the battery 145 into AC power to drive the MG 165. The MG 165 is a rotating electric machine that is driven by the AC power from the PCU 160 and applies a drive torque to the drive wheels 166 to make the vehicle 100 run.

[0026] The communication device 120 is a communication interface for transmitting and receiving signals with the server 300 via the communication network 400. The communication device 120 is also configured to be able to communicate with the communication device 260 of the power transmitting device 200. The communication between the communication device 120 and the communication network 400 and between the communication device 120 and the power transmitting device 200 is performed wirelessly.

[0027] The navigation device 125 includes a touch panel (not shown) and presents and guides the user to a destination specified by the user. The navigation device 125 transmits destination information input by the user to the server 300 via the communication device 120. The navigation device 125 receives candidate information of driving routes to the destination searched for by the server 300 and displays it on the touch panel. When the user selects a desired driving route from the displayed candidates, the navigation device 125 guides the user based on the selected driving route.

[0028] Camera 170 captures an image of the interior of vehicle 100. Camera 170 is, for example, a drive recorder. The image captured by camera 170 is transmitted to server 300 via ECU 110 and communication device 120. Server 300 can determine the number of passengers from the image of the interior of the vehicle from camera 170. Note that ECU 110 may calculate the number of passengers from the image of camera 170 instead of server 300, and in this case, information indicating the calculated number of passengers is transmitted to server 300.

[0029] The detection device 180 includes a suspension sensor 181, a seat sensor 182, and a seat belt sensor 183. The suspension sensor 181 is disposed on a suspension that holds each wheel. The suspension sensor 181 detects the load applied to each wheel, and detects the weight of passengers riding in the vehicle and baggage loaded in the passenger compartment, trunk, or luggage bed.

[0030] The seat sensor 182 is disposed in a passenger seat in the vehicle interior. The seat sensor 182 detects whether or not an occupant is sitting in the passenger seat. The seat sensor 182 can detect the number of passengers. The seat belt sensor 183 detects whether or not the seat belt is locked. Since it is mandatory to use the seat belt while the vehicle is traveling, the number of passengers can be detected by detecting the use state of the seat belt sensor 183. Detection information of each sensor included in the detection device 180 is transmitted to the server 300 via the ECU 110 and the communication device 120.

[0031] The RFID reader 175 is disposed in a trunk or a loading platform for loading luggage. When an RFID tag is attached to the luggage to be loaded, the RFID 175 can read information stored in the RFID tag. In this embodiment, the RFID reader 175 reads information related to the weight of the luggage from the RFID tag attached to the luggage. The read information is transmitted to the server 300 via the ECU 110 and the communication device 120.

[0032] It is not essential to include all of the camera 170, the sensors of the detection device 180, and the RFID reader 175, but it is sufficient to have at least one of them. The server 300 calculates the load weight based on the information detected by these sensors.

[0033] Next, the configuration of the power transmission device 200 will be described. The power transmission device 200 includes a power transmission unit 210, a power supply device 220, a control device 250, and a communication device 260. The power transmission unit 210 includes a plurality of power transmission coils 210A-210E. Note that, in FIG. 2, an example is shown in which the power transmission device 200 includes five power transmission coils 210A-210E arranged in a row on the road surface, but the number of power transmission coils is not limited to this, and may be four or less, or six or more. The power transmission coils may be arranged in a plurality of rows along the road surface.

[0034] The control device 250 includes a CPU and a memory, neither of which are shown, and performs overall control of other devices in the power transmitting device 200. Specifically, the control device 250 selects a power transmitting coil to be used for power transmission, based on information received from the vehicle 100 via the communication device 260, and determines the power to be supplied to each power transmitting coil.

[0035] The communication device 260 is a communication interface for wirelessly communicating with the vehicle 100. The control device 250 transmits and receives vehicle position information, information on the specifications of the power receiving device, information on the SOC (State of Charge) of the battery 145, billing information, and the like, via the communication device 260.

[0036] The power transmission coils 210A-210E are connected to the power supply device 220. The power supply device 220 is connected to an AC power source 230 arranged outside the power transmission device 200. The power supply device 220 converts the AC power received from the AC power source 230 into AC power of a predetermined frequency in accordance with a command from the control device 250, and outputs the AC power to the power transmission coils 210A-210E. At this time, the control device 250 supplies the AC power from the AC power source 230 to the power transmission coils, among the power transmission coils 210A-210E, above which the power reception coil 130 of the vehicle 100 is located, based on the position of the vehicle 100.

[0037] More specifically, for example, when the power receiving coil 130 is positioned above the power transmitting coil 210B in an opposing manner, the control device 250 supplies AC power from the power feeding device 220 to the power transmitting coil 210B. An electromagnetic field is formed around the power transmitting coil 210B by an AC current flowing through the power transmitting coil 210B. The power receiving coil 130 on the vehicle 100 side receives power from the power transmitting coil 210B in a non-contact manner through the electromagnetic field formed by the power transmitting coil 210B.

[0038] Then, when the power receiving coil 130 is removed from above the power transmitting coil 210B, the control device 250 controls the power feeding device 220 to stop the supply of AC power to the power transmitting coil 210B. By performing such a series of controls on each of the power transmitting coils 210A-210E, it is possible to transmit power to the traveling vehicle 100 in a non-contact manner. Naturally, even when the vehicle 100 is stopped on the power transmitting device 200, it is possible to transmit power from the power transmitting device 200 to the vehicle 100 in a non-contact manner. Note that the power transmitting coils 210A-210E may be arranged on the road surface of a travel lane, or may be arranged at a position where the vehicle stops at an intersection while waiting for a traffic light to turn on.

[0039] The control device 250 determines whether or not a power receiving coil is located above each power transmitting coil based on a sensor (not shown) provided in the power transmitting device 200 and / or vehicle position data transmitted from the vehicle 100.

[0040] [Details on route search and presentation] When a navigation device is used to search for a route to a destination and present it to a user, a route that can reach the destination from the current position in the shortest time or distance is generally selected with priority. However, when the electric vehicle has a large number of passengers or a large load, such as heavy loads, the power consumption is lower than when the load is small, and more power is consumed from the battery. This may result in the battery's SOC being depleted and the vehicle running out of power before arriving at the destination, or the SOC may not be sufficient when the vehicle arrives at the destination.

[0041] Therefore, in the system 10 according to the present embodiment, a method is adopted for searching for a driving route to a destination taking into consideration the load of the vehicle 100. More specifically, when searching for a driving route to a destination, if the vehicle has a large load, a driving route that can receive power while driving using a power transmission device arranged on the road surface is set to have a high priority. In this case, the arrival time may be delayed or the driving distance may be longer than a driving route that can reach the destination in the shortest time or distance. However, since the battery is charged while the user is in the vehicle while driving or waiting at a traffic light, it is possible to suppress a decrease in SOC and ensure the SOC at the time of arrival at the destination. This can eliminate the user's anxiety about running out of power while driving.

[0042] 3 is a diagram showing an example of a travel route selected by the server 300. In FIG. 3, it is assumed that the vehicle 100 is located at a current location 500 and departs for a destination 510.

[0043] 3, route RT1 is a driving route that can reach destination 510 in the shortest time or distance, which is searched for by a general method. Route RT2 is a driving route that passes through power transmission devices 200A and 200B that allow charging while traveling before arriving at destination 510. Route RT3 is a driving route that passes through power transmission devices 200C, 200D, and 200E that allow charging while traveling before arriving at destination 510.

[0044] The travel distance via route RT2 is longer than the travel distance via route RT1, and the travel distance via route RT3 is even longer than the travel distance via route RT2. Note that it is assumed that the additional amount of power consumed by traveling an extended distance on routes RT2 and RT3 compared to route RT1 is smaller than the amount of power that can be received from the power transmission devices arranged on each route.

[0045] When the server 300 receives information on the destination, SOC, and load from the vehicle 100, the server 300 predicts the SOC when the vehicle reaches the destination 510 when the route RT1 is selected, based on the relationship between the load and power cost stored in advance. If the predicted SOC value is smaller than a predetermined value, the server 300 determines the priority order of the routes RT2 and RT3 based on the amount of power shortage, the amount of power that can be charged by the power transmission device, and the delay time at the time of arrival at the destination 510 compared to when the route RT1 is selected.

[0046] Alternatively, the server 300 may determine the priority of selectable travel routes using a map such as that shown in Fig. 4. In Fig. 4, the priority of the travel routes is determined based on the SOC state and the load weight WT of the vehicle 100. In Fig. 4, the numbers in the table indicate the priority.

[0047] More specifically, server 300 stores a map for high SOC (FIG. 4(A)) and a map for low SOC (FIG. 4(B)) in storage device 305. For example, if the SOC at the time of route search is 50% or higher, the map for high SOC is selected, and if the SOC is less than 50%, the map for low SOC is selected.

[0048] In the high SOC map, when the load weight WT calculated from information from the detection device 180, the camera 170, etc. of the vehicle 100 is less than the first threshold value α (WT<α), the power consumption is relatively small, so the route RT1, which does not require charging while traveling, is set to the highest priority, followed by route RT2 and then route RT3.

[0049] When the load WT is equal to or greater than the first threshold value α and less than the second threshold value β (α≦WT<β), it is determined that charging during travel is necessary, and the route RT2 is set to the highest priority, followed by the route RT3. In this case, the route RT1 may be excluded from the priority setting, or may be set to a lower priority.

[0050] When the load WT is equal to or greater than the second threshold value β (β≦WT), the route RT3 that allows for more frequent charging during travel is set to the highest priority. In this case, the routes RT1 and RT2 may be excluded from the priority setting or may be set to a lower priority.

[0051] In the low SOC map, since the initial value of SOC at the start of traveling is low, the priority of the travel route where charging can be performed while traveling is set higher than in the high SOC map. Specifically, when the load amount WT is less than the first threshold value α (WT<α), the priority of the route RT2 is set highest, followed by the priority of the route RT3. When the load amount WT is equal to or greater than the first threshold value α and less than the second threshold value β (α≦WT<β), the priority of the route RT3 is set highest. Also, when the load amount WT is equal to or greater than the second threshold value β (β≦WT), the priority of the route RT3 is set highest.

[0052] In the example of FIG. 4, a case has been described in which there are three selection candidates for the travel route, but more travel routes may be set as selection candidates.

[0053] The server 300 transmits to the vehicle 100 the priority of each of the travel routes among the selection candidates and the delay time of arrival at the destination compared with the route RT1. In the vehicle 100, the information acquired from the server 300 is displayed on the screen of the navigation device 125. When the user selects a desired travel route from among the displayed travel route selection candidates, the navigation device 125 performs guidance according to the selected travel route.

[0054] When a driving route that is not subject to the priority order is selected, or when a driving route with a lower priority order is selected and it is predicted that the SOC will be insufficient and the vehicle will run out of power before arriving at the destination, the navigation device 125 may notify the user of the possibility of running out of power and, based on information from the server 300, provide the user with information about power supply stations installed in the vicinity of the selected driving route.

[0055] Fig. 5 is a flowchart for explaining details of the control executed by the vehicle 100 and the server 300 in the driving route presentation system 10 of Fig. 1. The flowchart of Fig. 5 is called from a main routine and executed in the ECU 110 of the vehicle 100 and the processor 310 of the server 300 when a predetermined condition is satisfied. Each step in the flowchart is realized by software processing of the ECU 110 and the processor 310, but some or all of the steps may be realized by hardware such as an LSI (Large Scale Integration) included in the ECU 110 and the processor 310.

[0056] 5, in step (hereinafter, step will be abbreviated as S) 100, vehicle 100 acquires destination information through a user's operation on navigation device 125, and then in S110 acquires sensor information including the SOC of battery 145, the number of passengers, the load, etc. based on information from various sensors mounted on vehicle 100. Then, in S120, vehicle 100 transmits vehicle information INFO including the destination and the sensor information to server 300 via communication network 400.

[0057] In S200, server 300 determines whether or not vehicle information INFO has been acquired from vehicle 100. If vehicle information INFO has not been acquired (NO in S200), the process returns to S200, and server 300 waits for vehicle information INFO to be transmitted from vehicle 100.

[0058] When the vehicle information INFO is acquired (YES in S200), the process proceeds to S210, where the server 300 calculates the load from the sensor information included in the vehicle information INFO, and searches for candidate driving routes based on the destination and the load using the map database 330 and the power transmitting device database 340. Details of the process of S200 will be described later with reference to Figs. 6 and 7.

[0059] When the selected candidates for the travel route are determined, the server 300 transmits route candidate information RTCD of the determined travel route to the vehicle 100 in S220.

[0060] When the vehicle 100 receives the route candidate information RTCD from the server 300 (S130), it then displays the acquired travel route candidate information on the navigation device 125 in S140. At this time, the priority order of each travel route candidate that has been searched and the delay time from the case where the travel route allows the driver to reach the destination in the shortest time or the shortest distance are also displayed.

[0061] Next, in S150, the vehicle 100 accepts a selection operation of a travel route by the user. Then, the vehicle 100 transmits to the server 300 selected route information RT regarding the selected travel route.

[0062] When the server 300 receives the selected route information RT from the vehicle 100 (S230), in S240, the server 300 edits information required for navigation (navigation information NVI) and transmits it to the vehicle 100. In S170, the vehicle 100 starts guidance (navigation) to the destination using the navigation device 125 based on the navigation information acquired from the server 300.

[0063] (First example of search processing) Fig. 6 is a flowchart showing a first example of the process of searching for a driving route executed in step S210 in Fig. 5. In Fig. 6, a configuration for searching for a driving route based on a predicted value of SOC upon arrival at the destination will be described.

[0064] 6, when the server 300 acquires the vehicle information INFO from the vehicle 100 in S200, the server 300 calculates the load weight WT of the vehicle 100 based on the information of the camera 170 and the detection information of various sensors included in the detection device 180 in S211. Then, the server 300 calculates the electricity consumption of the vehicle 100 based on the calculated load weight WT (S212). In S213, the server 300 calculates a predicted value of the SOC at the time of reaching the destination using the calculated electricity consumption, the SOC information of the vehicle 100, the distance of each travel route to the destination, and the chargeable amount during travel by the power transmitting device 200 on each travel route. Then, the server 300 determines the priority order of the selection candidates of the travel route according to the predicted SOC. Thereafter, in S220, the route candidate information RTCD including the determined priority order is transmitted to the vehicle 100.

[0065] (Second example of search process) Fig. 7 is a flowchart showing a second example of the process of searching for a travel route executed in step S210 in Fig. 5. In Fig. 7, a configuration for searching for a travel route using the map shown in Fig. 4 will be described.

[0066] 7, when server 300 acquires vehicle information INFO from vehicle 100 in S200, server 300 calculates the load weight WT of vehicle 100 based on the information from camera 170 and the detection information from various sensors included in detection device 180 in S211A. Then, server 300 selects one of the maps shown in FIG. 4 based on the SOC information of vehicle 100 in S212A. The server determines the priority of the selection candidates for each travel route based on the selected map and the calculated load weight WT in S213A. Thereafter, route candidate information RTCD including the determined priority is transmitted to vehicle 100 in S220.

[0067] By performing control according to the above-mentioned process, it is possible to search for a route that takes into account the vehicle's load when searching for a route using information on power transmission devices installed along the route. This makes it possible to ensure that a vehicle capable of wireless charging can be charged to the destination even if it is heavily loaded. Furthermore, it is possible to eliminate the user's anxiety about running out of power while driving.

[0068] In the above embodiment, the search for candidate driving routes to the destination is performed by the server 300. However, the search for a driving route may be performed by the vehicle 100 based on information in a database contained in the server 300.

[0069] In addition, if the vehicle 100 has an autonomous driving function, the vehicle 100 may select the driving route with the highest priority from among the driving routes presented by the server 300, and drive autonomously according to that driving route.

[0070] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. The scope of the present disclosure is defined by the claims, not by the description of the embodiments described above, and is intended to include all modifications within the meaning and scope of the claims.
