Description

[Technical Field]

[0001] The present disclosure relates to a control device, a program, and a control method. [Background technology]

[0002] Conventionally, there has been known a control device applied to a vehicle equipped with a power storage unit. The control device sets a driving route for the vehicle from a departure point of the vehicle to a set destination. Some control devices divide the driving route into multiple sections and set target temperatures for the power storage unit in order to prevent the regenerative power value or regenerative current value of the power storage unit from being limited. An example of such a control device is the control device disclosed in Patent Document 1. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-090287 Summary of the Invention [Problem to be solved by the invention]

[0004] When a target temperature of the power storage unit is set for each of the divided sections, there is a concern that the calculation load on the control device may increase.

[0005] The main objective of the present disclosure is to provide a control device, program, and control method that can reduce the calculation load of the control device while suppressing the occurrence of situations in which the regenerative power value or regenerative current value to the storage unit is limited. [Means for solving the problem]

[0006] The present disclosure provides a control device applied to a vehicle equipped with a power storage unit, a destination setting unit that sets a destination to which the vehicle is to move; a route setting unit that sets a travel route of the vehicle from a departure point of the vehicle to the set destination; a dividing unit that divides the set travel route into a plurality of temporary sections; a regeneration value prediction unit that predicts a regeneration value, which is either regenerative power or regenerative current to the power storage unit, in each of the divided multiple temporary sections; a combining unit that extracts, from the plurality of tentative sections, a tentative section in which the predicted regeneration value exceeds a limit value as an excess section, and combines adjacent excess sections from the extracted plurality of tentative sections to set the excess section as a limit section; a temperature setting unit that sets a target temperature of the power storage unit in the set restricted section and in a single excess section that is an excess section other than the restricted section among the plurality of excess sections; Equipped with.

[0007] The dividing unit divides the set travel route into a plurality of tentative sections. Here, when attempting to set a target temperature of the power storage unit for each of the plurality of tentative sections, there is a concern that the calculation load on the control device will increase.

[0008] Therefore, in the present disclosure, the combining unit extracts, from among the multiple tentative sections, a tentative section in which the predicted regeneration value exceeds a limit value as an excess section. The combining unit combines adjacent excess sections from among the extracted multiple excess sections to set the excess section as a limit section. The temperature setting unit sets target temperatures for the power storage unit in the set limit section and in a single excess section, which is an excess section other than the limit section among the multiple excess sections. The excess section is included in the section for which the target temperature is set because it is a section in which temperature management of the power storage unit is important in keeping the regeneration value below the limit value. Combining the tentative sections by the combining unit reduces the number of sections for which target temperatures should be set. Therefore, according to the present disclosure, it is possible to reduce the calculation load on the control device while suppressing the occurrence of a situation in which the regenerative power value or regenerative current value of the power storage unit is limited.

[0010] Several embodiments will be described with reference to the drawings. In several embodiments, functionally and / or structurally corresponding and / or associated parts may be assigned the same reference numerals or reference numerals that differ in the hundredth or more digit. For corresponding and / or associated parts, reference may be made to the descriptions of other embodiments.

[0011] First Embodiment A first embodiment of a control device according to the present disclosure will be described below with reference to the drawings. The control device of this embodiment is applied to an electrically powered vehicle such as an electric vehicle or a hybrid vehicle. The vehicle may be a passenger vehicle or an unmanned vehicle.

[0012] FIG. 1 shows the overall configuration of a control system including a host vehicle 40 equipped with a control device of this embodiment. In addition to the host vehicle 40, the control system also includes a charging station 11, an external server 20, and another vehicle 30. The charging station 11 is an external charging facility. The charging station 11 is installed, for example, in urban areas and on highways. The external server 20 is a device operated by a service provider that provides external information, which will be described later. The host vehicle 40, the charging station 11, the external server 20, and the other vehicle 30 are connected to each other so as to be able to communicate with each other via a communication network 10 (for example, the Internet). The communication network 10 is at least one of a wired network and a wireless network.

[0013] The external server 20 includes a processor 21, a communication unit 22, and a storage unit 23. In the external server 20, the processor 21, the communication unit 22, and the storage unit 23 are connected to one another via a communication bus 24.

[0014] The storage unit 23 includes a memory and a storage. The processor 21 controls the operation of the external server 20 by reading and executing a program stored in the storage unit 23. The communication unit 22 transmits and receives data via the communication network 10. The communication unit 22 transmits data to other devices in accordance with instructions from the processor 21. The communication unit 22 receives data transmitted from other devices and transmits the data to at least one of the processor 21 and the storage unit 23.

[0015] The host vehicle 40 includes a communication unit 50 and an ECU (Electronic Control Unit) 60, which is a control device. In this embodiment, the communication unit 50 corresponds to the "information receiving unit."

[0016] The communication unit 50 functions as an interface for transmitting and receiving data to and from communication devices external to the vehicle 40. The communication unit 50 is capable of communicating with the ECU 60. The communication unit 50 transmits and receives data via the communication network 10. The communication unit 50 receives data transmitted from devices external to the vehicle 40 in accordance with instructions from the ECU 60 and transmits the data to the ECU 60. The communication unit 50 receives current location information of the vehicle 40 detected by a GPS sensor (not shown) provided in the vehicle 40. The communication unit 50 transmits the received current location information to the ECU 60. The communication unit 50 includes a car navigation system and a user interface terminal for operating the car navigation system. In this embodiment, a user of the vehicle 40 inputs a destination of the vehicle 40 into the user interface terminal, and driving control of the vehicle 40 is performed based on information from the car navigation system.

[0017] The ECU 60 is a device that performs various controls of the vehicle 40, and includes a processor 61 and a storage unit 62 as hardware. In the ECU 60, the processor 61 and the storage unit 62 are connected to each other via a communication bus 63. In the vehicle 40, the drive system 90 and the air conditioner 80 can be controlled by their corresponding ECUs. However, for convenience, multiple ECUs are shown as one ECU 60 in FIG. 1.

[0018] The memory unit 62 includes a memory and a storage as hardware. The memory is a storage device for storing data used in the processing of the ECU 60. The memory provides the processor 61 with a working area for temporary use when the processor performs processing, for example. The memory includes, for example, a ROM or a RAM. The storage is a storage device for storing various programs and data to be read and executed by the processor 61, and is a non-transitory tangible storage medium. The storage includes, for example, an HDD or a flash memory. The storage stores program information and the like for various processes, which will be described later.

[0019] For example, program information stored in a non-transient physical recording medium is installed in the storage unit 62. The recording medium is, for example, a USB memory, a CD-ROM, or a DVD. Also, for example, program information transmitted via the communication network 10, such as over the air (OTA), is installed in the storage unit 62.

[0020] The host vehicle 40 is equipped with a drive system 90 for propelling the host vehicle 40. In this embodiment, as shown in FIG. 2, the drive system 90 is equipped with a charger 94, a storage battery 91 (corresponding to an "electricity storage unit"), an inverter 92, and a rotating electric machine 93. The storage battery 91 is a chargeable and dischargeable secondary battery, such as a lithium-ion storage battery or a nickel-metal hydride storage battery. The storage battery 91 can be charged by being connected to a charging station 11 via the charger 94 (for example, an on-board charger).

[0021] The inverter 92 has upper and lower arm switches, and performs powering control or regenerative control, which is switching control of the upper and lower arm switches. Powering control is switching control that converts the DC current output from the storage battery 91 into AC current and supplies it to the stator windings of the rotating electric machine 93. Regenerative control is switching control that converts the AC current output from the stator windings into DC current and supplies it to the storage battery 91 as charging current.

[0022] As shown in FIG. 3 , the host vehicle 40 is equipped with a temperature adjustment device 210 (corresponding to a "temperature adjustment device") that cools or heats the drive system 90. More specifically, the temperature adjustment device 210 is equipped with a circulation path 200 through which coolant circulates, an electric water pump 201, a radiator 202, an electric fan 203, and a battery heater 204. The water pump 201 is driven by power supplied from the storage battery 91, thereby circulating the coolant. The electric fan 203 is driven by power supplied from the storage battery 91 to rotate. The battery heater 204 is heated by power supplied from the storage battery 91, thereby raising the temperature of the coolant flowing through the storage battery 91 or the circulation path 200. In the example shown in FIG. 3 , an inverter 92, a rotating electric machine 93, and the storage battery 91 are arranged in this order in the circulation path 200 downstream of the water pump 201. Note that the arrangement order in the circulation path 200 is not limited to the order shown in FIG. 3 . The battery heater 204 is disposed, for example, between the rotating electric machine 93 and the storage battery 91 in the circulation path 200 .

[0023] A radiator 202 is provided in circulation path 200 between water pump 201 and storage battery 91. Radiator 202 cools the coolant flowing in via circulation path 200 and supplies the cooled coolant to water pump 201. The coolant flowing into radiator 202 is cooled by wind blown against radiator 202 as vehicle 40 travels and wind blown against radiator 202 by rotating fan 203.

[0024] Returning to the explanation of FIG. 2 , the vehicle 40 is equipped with an air conditioner 80 that conditions the air inside the vehicle cabin of the vehicle 40. More specifically, the air conditioner 80 is equipped with an electric compressor 81, an air conditioning heater 82, and a blower fan 83. The electric compressor 81 is driven by power supplied from a storage battery 91 to circulate refrigerant in the vehicle refrigeration cycle. The air conditioning heater 82 is driven by power supplied from the storage battery 91 to heat the vehicle cabin. The blower fan 83 is driven to rotate by power supplied from the storage battery 91.

[0025] The host vehicle 40 is equipped with sensors 70 that detect state quantities of on-board electrical equipment. More specifically, the sensors 70 include a voltage sensor 71, a current sensor 72, a battery temperature sensor 73, and an interior temperature sensor 74. The voltage sensor 71 detects the voltage between the terminals of the storage battery 91. The current sensor 72 detects the current flowing through the storage battery 91. The battery temperature sensor 73 detects the temperature of the storage battery 91. The interior temperature sensor 74 detects the interior temperature of the host vehicle 40. The detected values ​​of the sensors 70 are input to the ECU 60.

[0026] Next, the control executed by the ECU 60 will be described.

[0027] The ECU 60 performs powering control or regenerative control to feedback control the control amount of the rotating electric machine 93 to a command value. The control amount is, for example, torque. In each phase, the upper arm switch and the lower arm switch are alternately turned on. By powering control, the rotational power of the rotor of the rotating electric machine 93 is transmitted to the drive wheels of the host vehicle 40, causing the host vehicle 40 to travel.

[0028] The ECU 60 controls the air conditioning of the vehicle interior by energizing an electric compressor 81, an air conditioning heater 82, and a blower fan 83 so that the temperature detected by the interior temperature sensor 74 is set to a target value for the interior temperature.

[0029] When ECU 60 determines that vehicle 40 is parked at charging station 11 and that storage battery 91 is electrically connected to charging station 11, ECU 60 performs external charging control to charge storage battery 91 from an external power supply provided in charging station 11 via charger 94. The external charging control includes control of charger 94.

[0030] The ECU 60 performs temperature management control of the storage battery 91 over a period from when the host vehicle 40 departs from a departure point (for example, a home, an office, or a commercial facility) until it arrives at its destination. The temperature management control is a control for preventing the charge / discharge power or charge / discharge current of the storage battery 91 from being limited over a period from when the host vehicle 40 departs from the departure point until it arrives at its destination by controlling the temperature of the storage battery 91. The maximum charge / discharge power or maximum charge / discharge current of the storage battery 91 depends on the temperature of the storage battery 91. The temperature management control is executed before the host vehicle 40 travels toward the destination, and specifically, is executed when the host vehicle 40 is stopped at the departure point. The temperature management control will be described below.

[0031] The ECU 60 sets a travel route for the host vehicle 40 for one trip from the departure point to the destination of the host vehicle 40. The ECU 60 performs a division process for dividing the set travel route into a plurality of tentative sections.

[0032] In the temperature management control, target temperatures of the storage battery 91 are set at multiple points included in the travel route from the departure point to the destination. Here, when a target temperature of the storage battery 91 is set for each of multiple provisional sections, the calculation load on the ECU 60 increases as the number of provisional sections increases.

[0033] Therefore, in this embodiment, the ECU 60 performs a combining process that combines multiple temporary sections based on predetermined conditions, thereby reducing the number of temperature management sections for which target temperatures are to be set. This reduces the calculation load on the ECU 60 compared to when a target temperature is set for each of the multiple temporary sections.

[0034] The division process will be described with reference to FIG. 4. The ECU 60 includes a destination setting unit 100 and a route setting unit 101. The destination setting unit 100 receives destination information from the communication unit 50 and sets the destination of the host vehicle 40. For example, when the communication unit 50 determines that the user has input the destination of the host vehicle 40 to a user interface terminal included in the communication unit 50, the communication unit 50 transmits the input destination information to the ECU 60. The destination setting unit 100 sets a destination Dtgt of the host vehicle 40 based on the received destination information. The destination setting unit 100 inputs the set destination Dtgt to the route setting unit 101.

[0035] The route setting unit 101 receives current location information of the vehicle 40 from the communication unit 50 and recognizes the received current location of the vehicle 40 as a departure point Dini. The route setting unit 101 searches for a travel route MC that is a route from the departure point Dini to the destination Dtgt.

[0036] The ECU 60 includes a dividing unit 102. Based on information about the travel route MC input from the route setting unit 101, the dividing unit 102 divides the travel route MC into a plurality of tentative sections Spr.

[0037] In the division process, for example, external information is used. The external information is information outside the vehicle 40, and includes weather information, traffic information, and charging facility information. Specifically, the weather information includes the amount of rainfall, the amount of snowfall, the temperature, humidity, and the amount of solar radiation. The traffic information includes map information including road information, road elevation information, and legal speed limit information, as well as congestion information and traffic regulation information. The congestion information and traffic regulation information are, for example, VICS (registered trademark) information. The charging facility information includes location information of the charging station 11.

[0038] The external information is stored in, for example, the storage unit 23 of the external server 20 and updated each time. The communication unit 22 of the external server 20 transmits the external information to the communication unit 50 via the communication network 10. The communication unit 50 transmits the received external information to the division unit 102. The division unit 102 uses the received external information for the division process. Note that the division unit 102 may use external information transmitted directly from another vehicle 30 to the communication unit 50 via vehicle-to-vehicle communication for the division process. Furthermore, the division unit 102 may receive location information of the charging station 11 transmitted by the charging station 11 via the communication network 10 and the communication unit 50 and use the information for the division process.

[0039] Below, some specific examples of division methods using external information will be explained.

[0040] Based on the received road information and road elevation information, the dividing unit 102 may divide the travel route MC into sections where it has determined that the travel path of the vehicle 40 has an uphill slope and sections where it has determined that the travel path of the vehicle 40 has a downhill slope, as tentative sections.

[0041] The dividing unit 102 may select a point where the amount of change in traffic flow exceeds a traffic flow threshold as a dividing point of the travel route MC.

[0042] The dividing unit 102 predicts points at which the control mode switches from regenerative control to powering control and points at which the control mode switches from powering control to regenerative control, based on traffic information. The dividing unit 102 may select the predicted switching points as dividing points of the travel route MC.

[0043] The dividing unit 102 may select a point on the travel route MC where the change in the legal speed exceeds the speed threshold as a dividing point of the travel route MC. An example of the change in the expected speed exceeding the speed threshold is when the travel route changes from an ordinary road to an expressway, or when the travel route changes from an expressway to an ordinary road.

[0044] The dividing unit 102 predicts the number of stops of the host vehicle 40 on the travel route MC based on information about traffic congestion occurring on the travel route MC, the number of traffic lights present on the travel route MC, the number of crosswalks present on the travel route MC, seasonal information, and time of day information. The dividing unit 102 may divide the travel route MC into sections where the predicted number of stops exceeds a number threshold.

[0045] The ECU 60 includes a regeneration value prediction unit 103 and a combination unit 104. Information on the temporary sections Spr is input to the regeneration value prediction unit 103 and the combination unit 104 from the division unit 102. The information on the temporary sections Spr includes information on the start and end positions of each temporary section Spr on the travel route MC, external information on each temporary section Spr, and time information on each temporary section Spr.

[0046] The regeneration value prediction unit 103 predicts the SOC of the storage battery 91 in each tentative section Spr based on information about each tentative section Spr. Specifically, the regeneration value prediction unit 103 predicts the SOC when the temperature adjustment control of the storage battery 91 is not performed by the temperature adjustment device 210. In order to predict the SOC of each tentative section Spr, the regeneration value prediction unit 103 predicts the power consumption of the target equipment 300 in each tentative section Spr. The target equipment 300 is onboard equipment of the host vehicle 40, including the air conditioning device 80 and the drive system 90, and is equipment that operates by receiving power from the storage battery 91. The regeneration value prediction unit 103 predicts, for example, the power consumption at a prediction point in each tentative section Spr. An example of a method for predicting the power consumption of the target equipment 300 will be described below.

[0047] First, we will explain how to predict the power consumption of the drive system 90. The regeneration value prediction unit 103 predicts the power consumption of the drive system 90 at a predicted point in each temporary section Spr as the power consumption required for traveling the vehicle 40, based on road information for each temporary section Spr and map information including road elevation information and legal speed information.

[0048] Next, a method for predicting the power consumption of the air conditioner 80 will be described. The regeneration value prediction unit 103 predicts the power consumption of the air conditioner 80 at the predicted point of each temporary section Spr based on the interior environmental state of the vehicle 40 at the predicted point of each temporary section Spr. The interior environmental state is the detected values ​​of temperature and humidity inside the vehicle 40 and the target value of the interior temperature set by the user of the vehicle 40.

[0049] The regeneration value prediction unit 103 predicts the total value of the predicted power consumption of the drive system 90, the air conditioner 80, etc. as the power consumption of the target device 300.

[0050] The regeneration value prediction unit 103 predicts the temperature of the storage battery 91 at the prediction point of each tentative section Spr, assuming that the temperature adjustment control of the storage battery 91 is not performed by the temperature adjustment device 210. The regeneration value prediction unit 103 predicts the temperature of the storage battery 91 at the prediction point of each tentative section Spr, for example, based on the power consumption of the target device 300 at the prediction point of each tentative section Spr.

[0051] The regeneration value prediction unit 103 predicts the SOC at a predicted point on each tentative section Spr based on the predicted power consumption of the target device 300, the predicted temperature of the storage battery 91, and information on each tentative section Spr that constitutes the travel route MC. The regeneration value prediction unit 103 predicts a lower SOC the higher the power consumption of the target device 300, and predicts a higher SOC the lower the power consumption of the target device 300. When regenerative control is performed on the travel route MC, the regeneration value prediction unit 103 calculates the regenerative power at the predicted point where regenerative control will be performed, and predicts the SOC taking the calculated regenerative power into account.

[0052] The regeneration value prediction unit 103 predicts the SOC and temperature at the previous prediction point, and then predicts the SOC and temperature at the next prediction point based on the SOC and temperature at the previous prediction point and the power consumption of the target device 300 predicted at the next prediction point. The regeneration value prediction unit 103 predicts the transition of the SOC and temperature of the storage battery 91 on the travel route MC by sequentially predicting the power consumption of the target device 300 and the SOC and temperature of the storage battery 91 at multiple prediction points.

[0053] The regeneration value prediction unit 103 calculates the limit power Plim at the prediction point of each tentative section Spr based on the SOC of the storage battery 91 predicted at the prediction point of each tentative section Spr and the temperature of the storage battery 91. The limit power Plim is a limit value of the charging power of the storage battery 91. The limit power Plim may be the same value as the maximum charging power of the storage battery 91, or may be a value smaller than the maximum charging power (for example, a value between 85% and 95% of the maximum charging power).

[0054] The regeneration value prediction unit 103 predicts regenerative power Pprc at a prediction point in each temporary section Spr. The regenerative power Pprc is power generated by regenerative control. The regenerative value prediction unit 103 predicts the regenerative power Pprc based on, for example, traffic information. Specifically, for example, the regenerative value prediction unit 103 predicts a larger regenerative power Pprc the greater the gradient of the downhill road in the temporary section Spr, and predicts a smaller regenerative power Pprc the greater the gradient of the uphill road in the temporary section Spr. Specifically, for example, the regenerative value prediction unit 103 predicts a larger regenerative power Pprc the greater the number of decelerations of the host vehicle 40 in the temporary section Spr, and predicts a smaller regenerative power Pprc the fewer the number of decelerations of the host vehicle 40 in the temporary section Spr. The regenerative value prediction unit 103 inputs the predicted regenerative power Pprc to the combination unit 104. The regeneration value predicting unit 103 may predict the regenerative power Pprc by taking into account, for example, air resistance, rolling resistance, and acceleration resistance that occur when the host vehicle 40 travels.

[0055] The combining unit 104 performs a combining process. Specifically, the combining unit 104 extracts, from among the multiple tentative sections Spr set by the dividing unit 102, a tentative section in which the regenerative power Pprc predicted by the regenerative value predicting unit 103 exceeds the predicted limit power Plim, as an excess section. The combining unit 104 combines adjacent excess sections from among the multiple extracted excess sections, and sets the combined section as a limit section.

[0056] A specific example of a method for setting the limited intervals will be described using Figure 5. Figure 5(A) shows nine tentative intervals Spr(1) to Spr(9). Of the first to ninth tentative intervals Spr(1) to Spr(9), the regeneration value prediction unit 103 extracts the second, third, fifth, sixth, and eighth tentative intervals Spr(2), Spr(3), Spr(5), Spr(6), and Spr(8) as excess intervals in which the regenerative power Pprc exceeds the limited power Plim.

[0057] 5(B), of the extracted second, third, fifth, sixth, and eighth temporary intervals Spr(2), Spr(3), Spr(5), Spr(6), and Spr(8), the combining unit 104 sets the adjacent second and third temporary intervals Spr(2), Spr(3) and the adjacent fifth and sixth temporary intervals Spr(5), Spr(6) as restricted intervals. Of the second, third, fifth, sixth, and eighth temporary intervals Spr(2), Spr(3), Spr(5), Spr(6), and Spr(8), which are excess intervals, the combining unit 104 sets the eighth temporary interval Spr(8), which is not a restricted interval, as a single excess interval.

[0058] After setting the restricted sections and the single excess section, the combining unit 104 newly reassigns the sections. Specifically, the combining unit 104 reassigns the nine provisional sections Spr(1) to Spr(9) to seven main sections Scom(1) to Scom(7). In FIG. 5(B), the second and fourth main sections Scom(2) and Scom(4) are restricted sections, and the sixth main section Scom(6) is the single excess section. The first, third, fifth, and seventh main sections Scom(1), Scom(3), Scom(5), and Scom(7) correspond to the first, fourth, seventh, and ninth provisional sections Spr(1), Spr(4), Spr(7), and Spr(9).

[0059] Incidentally, the combining unit 104 sets, as a non-exceeding section, a tentative section in which the regenerative power Pprc is equal to or less than the limit power Plim, among the plurality of tentative sections set by the dividing unit 102. The combining unit 104 combines, among the plurality of tentative sections set by the dividing unit 102, adjacent non-exceeding sections into one non-exceeding section.

[0060] As shown in FIG. 4, the ECU 60 includes a temperature setting unit 105 and an operation unit 106. The temperature setting unit 105 sets a target temperature Tgt of the storage battery 91 in the restricted section and the individual exceedance section set by the combining unit 104. In this embodiment, the temperature setting unit 105 does not set a target temperature Tgt in the non-exceedance section among the multiple temporary sections set by the dividing unit 102. This reduces the calculation load of the ECU 60. In the example shown in FIG. 5(B) above, the non-exceedance sections are the first, third, fifth, and seventh main sections Scom(1), Scom(3), Scom(5), and Scom(7).

[0061] The operation unit 106 controls the temperature adjustment device 210 to energize the temperature Td detected by the battery temperature sensor 73 in each restricted section and each individual exceedance section to the target temperature Tgt set for each section. When the operation unit 106 wants to lower the detected temperature Td, it increases the rotation speed of the fan 203, for example. When the operation unit 106 wants to raise the detected temperature Td, it energizes the battery heater 204, for example.

[0062] In this embodiment, the temperature setting unit 105 sets the target temperature Tgt in the first half of the restricted section and the first half of the individual exceedance section. Specifically, it sets the target temperature Tgt at the start point of the restricted section and the start point of the individual exceedance section. This allows the temperature of the storage battery 91 to reach the target temperature Tgt as quickly as possible in the restricted section and the individual exceedance section. As a result, it is possible to increase the proportion of the restricted section in which the temperature of the storage battery 91 reaches the target temperature Tgt, or to increase the proportion of the individual exceedance section in which the temperature of the storage battery 91 reaches the target temperature Tgt. This allows the proportion of the restricted section and the individual exceedance section in which the regenerative power of the rotating electric machine 93 is not limited to be increased.

[0063] 6 is a flowchart showing the procedure of the division process and the combination process executed by the ECU 60. This process is executed after the destination of the vehicle 40 is input to the user interface terminal. The determination method and setting method in each of the following steps are the same as those described with reference to FIG.

[0064] In step S10, the dividing unit 102 acquires information about the travel route MC. In step S11, the dividing unit 102 divides the travel route MC into a plurality of tentative sections Spr based on the acquired information about the travel route MC. In step S12, the combining unit 104 assigns section numbers to the divided plurality of tentative sections Spr. In this embodiment, the section numbers are assumed to be 1, 2, 3, ..., Num. In other words, the travel route MC is divided into Num sections.

[0065] In step S13, the combining unit 104 sets the first tentative section Spr(1) as the first real section Scom(1).

[0066] In step S14, the regenerative power prediction unit 103 predicts the SOC at the prediction point of the (i+1)th temporary section Spr(i+1). i is a positive integer and is a number for identifying the temporary sections in order of appearance from the departure point Dini. The initial value of i is 1.

[0067] Also, in step S14, the regeneration value prediction unit 103 predicts the temperature of the storage battery 91 at the predicted point of the i+1th temporary section Spr(i+1), assuming that the temperature control of the storage battery 91 is not performed by the temperature control device 210.

[0068] In step S15, the regeneration value prediction unit 103 calculates the limited power Plim at the prediction point in the i+1th tentative section Spr(i+1). In step S16, the regeneration value prediction unit 103 predicts the regeneration power Pprc at the prediction point in the i+1th tentative section Spr(i+1).

[0069] In step S17, the coupling unit 104 determines whether the regenerative power Pprc of the i+1th tentative section Spr(i+1) predicted in step S16 is greater than the limited power Plim of the i+1th tentative section Spr(i+1) calculated in step S15.

[0070] If it is determined that the regenerative power Pprc is greater than the limit power Plim, the process proceeds to step S18. In step S18, the combining unit 104 sets the flag of the (i+1)th tentative section Spr(i+1) to "1." A flag of 1 indicates an excess section, and a flag of 0 indicates a non-excess section.

[0071] On the other hand, if it is determined that the regenerative power Pprc is equal to or less than the limit power Plim, the process proceeds to step S19. In step S19, the combining unit 104 sets the flag of the (i+1)th temporary section Spr(i+1) to "0".

[0072] In step S20, the combining unit 104 determines whether the flag of the i-th tentative interval Spr(i) is equal to the flag of the i+1-th tentative interval Spr(i+1). If it is determined that the flags are equal, it is determined that there are consecutive non-exceeding intervals or consecutive exceeding intervals, and the process proceeds to step S21. In step S21, the combining unit 104 increments i by 1. Thereafter, the processes of steps S14 to S20 are continued until a positive determination is made in step S20.

[0073] On the other hand, if it is determined in step S19 that the flag of the i-th tentative section Spr(i) and the flag of the i+1-th tentative section Spr(i+1) are different, it is determined that a switch has been made from one of the non-exceeding section and the exceeding section to the other, and the process proceeds to step S22. In step S22, the combining unit 104 increments the number j by 1. j is a positive integer and is a number for identifying this section in the order of appearance from the departure point Dini. The initial value of j is 1.

[0074] In step S23, the combining unit 104 sets the (i+1)th temporary interval Spr(i+1) as the jth main interval Scom(j). Note that in step S23, if it is determined in step S20 that the excess intervals are continuous, multiple continuous excess intervals are combined into one jth main interval Scom(j). In this case, the jth main interval Scom(j) is a restricted interval. Also, in step S23, if it is determined in step S20 that the non-exceeding intervals are continuous, multiple continuous non-exceeding intervals are combined into one jth main interval Scom(j).

[0075] In the following step S24, the combining unit 104 determines whether or not i exceeds the temporary section number Num. If it is determined that the number i is equal to or less than the temporary section number Num, the process proceeds to step S14. On the other hand, if it is determined that the number i exceeds the temporary section number Num, the series of processes shown in FIG. 6 ends.

[0076] By combining parts of the plurality of tentative sections Spr by the combining unit 104, the number of divided sections of the travel route MC can be reduced.

[0077] 7 is a flowchart showing the procedure of the temperature planning process executed by the temperature setting unit 105. This process is executed after the process shown in FIG.

[0078] In step S30, information on the first to K main sections Scom(1) to Scom(K) set in the process shown in Fig. 6 is obtained, where K is the number of main sections.

[0079] In step S31, restricted sections and single excess sections are extracted from the 1st to Kth main sections Scom(1) to Scom(K). Then, the extracted restricted sections and single excess sections are designated as the 1st to Lth target sections Sre(1) to Sre(L) in order of proximity to the departure point Dini, where L is the number of target sections.

[0080] In step S32, a temporary target temperature for the rth target section Sre(r) is set. The initial value of r is 1. In step S33, it is determined whether or not setting of temporary target temperatures for all target sections Sre(1) to Sre(L) has been completed. If it is determined in step S33 that not all have been completed, the process proceeds to step S34, where r is incremented by 1. Thereafter, the process returns to step S32.

[0081] In steps S32 to S34, a tentative target temperature for the next target section is set from among a plurality of candidate temperatures included in the temperature range that the storage battery 91 can assume relative to the tentative target temperature for the previous target section, thereby reducing the calculation load on the ECU 60.

[0082] If it is determined in step S33 that all the processes are completed, the process proceeds to step S35. In step S35, time-series data of the provisional target temperatures set in each of the target sections Sre from the first target section Sre(1) to the Lth target section Sre(L) (hereinafter, provisional temperature transition data Ttri) is generated.

[0083] FIG. 8 shows an example of the virtual temperature transition data Ttri. FIG. 8(A) shows an example of virtual temperature transition data of a comparative example in which sections are not combined, and FIG. 8(B) shows an example of virtual temperature transition data of this embodiment. In this embodiment, by combining sections, the number of virtual target temperatures set can be reduced. In addition, in this embodiment, the number of virtual target temperatures set can also be reduced by setting the virtual target temperature for the next target section from among multiple candidate temperatures included in the temperature range that the storage battery 91 can assume relative to the virtual target temperature for the previous target section.

[0084] 7, in step S36, predicted regenerative power Ptot, which is a predicted value of regenerative power in each of the target sections Sre(1) to Sre(L), is calculated. The processing of step S36 will be described with reference to FIG.

[0085] In step S50, assuming that the temperature of the storage battery 91 in the m-th target section Sre(m) is set to the tentative target temperature set in step S32, the limit power PL of the storage battery 91 in the m-th target section Sre(m) is calculated. The initial value of m is 1. The limit power PL, like the limit power Plim, is the maximum charge power of the storage battery 91. For example, the limit power PL may be calculated based on map information that associates the tentative target temperature with the limit power PL.

[0086] In step S51, the regenerative power PR in the m-th target section Sre(m) is predicted. The method for predicting the regenerative power PR is the same as the method for predicting the regenerative power in the regeneration value predicting unit 103, for example.

[0087] In step S52, it is determined whether the regenerative power PR predicted in step S51 is greater than the limit power PL calculated in step S50. If it is determined that the regenerative power PR is greater than the limit power PL, the process proceeds to step S53. In step S53, the predicted regenerative power Ptot in the mth target section Sre(m) is set to the limit power PL calculated in step S50.

[0088] On the other hand, if it is determined that the regenerative power PR is equal to or less than the limit power PL, the process proceeds to step S54. In step S54, the predicted regenerative power Ptot in the m-th target section Sre(m) is set to the regenerative power PR calculated in step S51.

[0089] In step S55, it is determined whether or not calculation of the predicted regenerative power Ptot has been completed for all target sections Sre(1) to Sre(L). If it is determined in step S55 that all calculations have not been completed, the process proceeds to step S56, where m is incremented by 1. Thereafter, the process proceeds to step S50. On the other hand, if it is determined in step S55 that all calculations have been completed, the process proceeds to step S37 in FIG. 7.

[0090] In step S37, the temperature adjustment power Ptem is calculated for each target section Sre(1) to Sre(L). The temperature adjustment power Ptem is the power consumption of the temperature adjustment device 210 to bring the temperature of the storage battery 91, which is the controlled variable, to the temporary target temperature set in step S32. The temperature of the storage battery 91, which is the controlled variable, is, for example, the temperature predicted in step S14 of FIG.

[0091] In step S38, the temperature control power Ptem is subtracted from the predicted regenerative power Ptot in each target section Sre(1) to Sre(L) to calculate the power difference. The power differences in each target section Sre(1) to Sre(L) are then added together to calculate the power balance Pint. The power balance Pint(n) is linked to the virtual temperature transition data Ttri(n) generated in step S35 and stored in the memory unit 62. n indicates the number of searches, which will be described later.

[0092] In step S39, it is determined whether the search count n has reached the search threshold Cth. The initial value of the search count n is "1." If it is determined that the search count n is less than the search threshold Cth, the process proceeds to step S40, where n is incremented by 1. Thereafter, the process proceeds to step S31. The search threshold Cth is set to, for example, "L x number of candidate temperatures."

[0093] If it is determined in step S39 that the search count n has reached the search threshold Cth, the process proceeds to step S41. In step S41, the virtual temperature transition data Ttri corresponding to the largest power balance Pint among the n power balance Pint is selected. Then, the L virtual target temperatures constituting the selected virtual temperature transition data Ttri are set as the first to L target temperatures Tgt(1) to Tgt(L) in the first to L target sections Sre(1) to Sre(L).

[0094] The operation unit 106 shown in FIG. 4 energizes the temperature adjustment device 210 to control the detected temperature Td of the battery temperature sensor 73 in the first to Lth target sections Sre(1) to Sre(L) to the first to Lth target temperatures Tgt(1) to Tgt(L). This allows the regenerative power to be efficiently stored in the storage battery 91 when it is generated. Furthermore, according to this embodiment, as illustrated in FIG. 10, the number of searches n in the temperature management control can be reduced compared to the comparative example. This reduces the calculation load on the ECU 60.

[0095] 6 and 7 again, and may re-execute the temperature plan for the storage battery 91 if it determines that a predetermined condition is met after completing the processing of FIG. 7. The predetermined condition is, for example, a condition that the difference between the detected temperature Td and the target temperature Tgt exceeds a predetermined difference after completing the processing of FIG. 7. The predetermined difference is, for example, a value that prevents the detected temperature Td from becoming the target temperature Tgt even through temperature adjustment control by the temperature adjustment device 210.

[0096] <Modification of the first embodiment> The temperature setting unit 105 may allow the setting of the target temperature Tgt in some of the non-exceeding sections.

[0097] Second Embodiment The second embodiment will be described below with reference to the drawings, focusing on differences from the first embodiment. In this embodiment, when the temperature setting unit 105 determines that the number L of target sections Sre is greater than the section threshold Lth, the temperature setting unit 105 performs a resetting process to reset the single excess section and the restricted section so that the number L of target sections Sre is equal to or less than the section threshold Lth. This process is performed to reduce the calculation load on the ECU 60.

[0098] 11 is a flowchart showing the procedure of the temperature planning process executed by the temperature setting unit 105 and the combining unit 104. Of the processes shown in FIG.

[0099] After completion of step S31, in step S42, the number L of target sections Sre is calculated based on the information of the first to Lth target sections Sre(1) to Sre(L) set in step S31. Then, it is determined whether the number L of target sections Sre is greater than the section threshold Lth. If it is determined in step S42 that the number L of target sections Sre is equal to or less than the section threshold Lth, the process proceeds to step S32. The section threshold Lth is a value determined from the processing capacity of the ECU 60.

[0100] On the other hand, if it is determined that the number L of target sections Sre is greater than the section threshold Lth, the process proceeds to step S43, where recombination processing is performed. Fig. 12 is a flowchart showing the procedure of the recombination processing.

[0101] In step S60, similar to step S51, the regenerative power PR in the first to Lth target sections Sre(1) to Sre(L) is predicted.

[0102] In step S61, the first to Lth target sections Sre(1) to Sre(L) are prioritized based on the predicted regenerative power PR. In this embodiment, the section with the larger regenerative power predicted in step S60 is assigned a higher priority.

[0103] In step S62, target sections Sre are selected from the first to Lth target sections Sre(1) to Sre(L) in order of decreasing priority, and the number of target sections Sre is the same as the section threshold Lth. Of the first to Lth target sections Sre(1) to Sre(L), the target sections Sre that are not selected are treated as non-exceeding sections. If a target section Sre treated as a non-exceeding section is adjacent to a tentative section Spr of a non-exceeding section, the target section Sre treated as a non-exceeding section and the tentative section Spr of the non-exceeding section adjacent to this target section Sre are combined into a single non-exceeding section.

[0104] The selected target sections are then set as the first to Lth target sections Sre(1) to Sre(Lth) in order of proximity to the departure point.Then, the process proceeds to step S32 in FIG.

[0105] In this embodiment, L is changed to Lth in step S33 of FIG. 11 and step S55 of FIG. 9, and Cth is changed to Lth in step S39 of FIG.

[0106] An example of the recombination process is shown in Fig. 13. For convenience, the number of target sections Sre is set to five in the example shown in Fig. 13. Fig. 13(A) shows the target section Sre before the recombination process. Fig. 13(B) shows the target section Sre after the recombination process.

[0107] The ECU 60 selects target sections Sre in the same number as the section threshold Lth in descending order of priority. Of the first to fifth target sections Sre(1) to Sre(5), the ECU 60 treats the unselected third and fifth target sections Sre(3) and Sre(5) as non-exceeding sections. The ECU 60 sets the selected first, second, and fourth target sections Sre(1), Sre(2), and Sre(4) as the first to third target sections Sre(1) to Sre(3) in descending order of proximity to the departure point.

[0108] FIG. 14 shows another example of the recombination process.

[0109] The ECU 60 selects target sections Sre in the order of highest priority, the number of which is equal to the section threshold Lth. Of the first to fifth target sections Sre(1) to Sre(5), the ECU 60 treats the second and third target sections Sre(2) and Sre(3) that were not selected as non-exceeding sections. The ECU 60 sets the selected first, fourth, and fifth target sections Sre(1), Sre(4), and Sre(5) as the first to third target sections Sre(1) to Sre(3) in the order of closest to the departure point.

[0110] According to the present embodiment described above, the number of intervals for setting the target temperature of the storage battery 91 can be reduced, while the target temperature of the storage battery 91 can be preferentially set for intervals with high temperature adjustment priority.

[0111] <Other embodiments> The above-described embodiments may be modified as follows.

[0112] The regenerative value predicted by the regenerative value predicting unit 103 is not limited to regenerative power, but may be regenerative current. In this case, it is sufficient that the limit current is calculated instead of the limit power.

In this case, the ECU 60 may acquire the calculation results of the processes of Figures 6, 7, 9, 11, and 12 executed by the server.
