Description

[Technical field]

[0001] The present invention relates to a power management system, a power management method, and a power management program. [Background technology]

[0002] In recent years, vehicles such as HVs, PHVs, and EVs have become widespread, but there is a limit to the amount of electricity that can be stored in drive batteries. For this reason, there is a risk that the vehicle will not be able to secure enough power to travel from its current location to its destination. To solve this type of problem, the technology described in Patent Document 1 has been proposed. According to the technology described in Patent Document 1, a predicted value of the remaining energy in the battery when the electric vehicle reaches the destination is calculated, and a notification device issues a notification based on the predicted value of the remaining energy.

[0003] In recent years, with the development of vehicle driving assistance technology and automatic driving technology, it is becoming possible for a vehicle to automatically travel from its current location to its destination without the driver having to drive the vehicle if the destination is input. In this case, the vehicle occupants have more time to kill while staying in the vehicle, and they have more opportunities and time to enjoy entertainment.

[0004] When a vehicle occupant enjoys entertainment in the vehicle cabin, it is considered that the vehicle occupant watches a movie displayed on a display device that is pre-installed in the vehicle. It is also considered that the vehicle occupant brings a mobile terminal such as a smartphone, a tablet terminal, or a laptop computer into the vehicle cabin and enjoys entertainment while charging the mobile terminal in the vehicle cabin. In this case, the amount of power consumption required to reach the destination changes depending on the needs of the vehicle occupant. For this reason, it is desirable to manage the power consumption used in the vehicle so as to meet these needs.

[0005] The technology described in Patent Document 1 only provides passive notifications, and notification control starts when the usage limit is approached. Therefore, vehicle occupants can use the vehicle without worrying about power until the system notifies them that the usage limit is approached.

[0006] In this case, even if an event occurs that requires a large amount of power consumption when the power usage upper limit is reached, there is a risk that the usage will be restricted and the power consumption will not be possible. Conversely, the vehicle occupants may be overly cautious about such power consumption and hesitate to consume power even if there is a margin of power consumption until the destination is reached. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Patent Publication No. 2021-178566 Summary of the Invention [Problem to be solved by the invention]

[0008] An object of the present disclosure is to provide a power management system, a power management method, and a power management program that enable appropriate management of the amount of power consumption until reaching a destination. [Means for solving the problem]

[0009] According to the invention described in claim 1, the calculation unit calculates the amount of driving power consumed while the vehicle 10 is traveling until the destination is reached, as well as the consumption-related power amount required to execute the functions of the vehicle equipment used until the destination is reached, based on power consumption parameters for power consumption within the vehicle. The creation unit creates a power usage plan for traveling to the destination based on the amount of driving power and the consumption-related power amount. The determination unit determines whether or not the use of the current power usage plan is appropriate, for example, whether or not it is impossible to continue, based on the power consumption parameters.

[0010] For example, when power consumption parameters that consume electricity within the vehicle are updated, such as changes in the number of vehicle occupants or their riding conditions, or operation input information to the operation input unit of the vehicle occupants (e.g., personal setting information, air conditioner setting status, personal preference information (information on entertainment viewing plans such as movies)), the judgment unit judges whether or not it is appropriate to use the current power usage plan based on the power consumption parameters.

[0011] If the judgment unit judges that the current power usage plan is inappropriate, the creation unit creates an updated power usage plan that is different from the current power usage plan. Therefore, even if an event occurs that requires a large amount of power consumption when the power usage upper limit is approached, the system will be able to consume power in response to this event. This allows appropriate management of power consumption until the destination is reached.

[0012] As described in claim 3, the notification control unit controls notification of the updated power usage plan to the vehicle occupant, thereby making the vehicle occupant aware of the amount of power to be consumed until the destination is reached. If there is a margin for power consumption, the vehicle occupant will not be likely to pay excessive attention to such power consumption, and can consume power with a margin for it until the destination is reached.

[0014] Hereinafter, several embodiments of a vehicle power management system 1 will be described with reference to the drawings. In each embodiment described below, components that perform the same or similar operations are denoted by the same or similar reference numerals, and descriptions thereof will be omitted as necessary.

[0015] (First embodiment) The power management system 1 shown in Fig. 1 is mounted on a vehicle 10. Here, the vehicle 10 is shown as an electrically powered vehicle 10 (EV), but the system may also be applied to a hybrid vehicle (HV) combined with an internal combustion engine, a plug-in hybrid vehicle (PHV, PHEV), and the like.

[0016] The vehicle 10 is equipped with on-board devices that operate by receiving power from a battery 11. The on-board devices shown here include an occupant detection unit 14, a communication unit 15, an operation input unit 16, a display device 17, a surrounding environment acquisition unit 18, and other vehicle devices 19. ECU stands for Electronic Control Unit. The battery 11 refers to an auxiliary battery that supplies power to the ECUs 12 and 13 together with an assembled battery formed by connecting battery cells in series as a power source for driving.

[0017] The ECU 12 is connected to another ECU 13 via a network. The ECUs 12 and 13 may be classified into a display ECU for controlling the notification of information to vehicle occupants, a surroundings monitoring ECU for acquiring the state of the surrounding environment of the vehicle 10 and monitoring the surroundings of the vehicle 10, and a driving control ECU for controlling the driving of the vehicle 10. In addition, the ECU may be configured as an integrated ECU in which some or all of the functions of these ECUs 12 and 13 are integrated. Here, the ECU 12 for realizing the functions of the present application is described with a different reference number 12 from the other ECUs 13, but the ECU 12 may be configured by integrating the functions installed in the other ECUs 13.

[0018] The ECU for the driving control system includes an electronic control device that controls the electric driving of the vehicle 10 using the vehicle driving motor in response to driving operations by the driver, or an electronic control device that realizes an autonomous driving mode according to various levels of autonomous driving. This allows the vehicle 10 to perform driving control in each driving mode, whether manual driving or a predetermined level of autonomous driving.

[0019] The ECU 12 is connected to an occupant detection unit 14, a communication unit 15, an operation input unit 16, and a display device 17. The occupant detection unit 14 is configured to detect vehicle occupants using various sensors such as a DSM 14a, a PSM 14b, a seating sensor 14c, and a seat belt sensor (not shown).

[0020] The DSM 14a is a so-called driver status monitor, and is a high-performance recognition system that automatically recognizes the face and body of the driver using a camera and detects the driving state of the driver. The DSM 14a detects the driver's state with high accuracy. The PSM 14b is a so-called passenger status monitor that automatically recognizes the faces and bodies of vehicle occupants other than the driver using a camera to detect the state of the vehicle occupants, and detects the state of the other vehicle occupants with high performance. The seating sensor 14c is disposed in each seat in which the vehicle occupant sits, and detects the seat in which the vehicle occupant sits. The seat belt sensor detects the fastening state of the seat belt of the vehicle occupant. The occupant detection unit 14 can detect which seat the vehicle occupant is sitting in, the face of the driver or other vehicle occupant, the position of a part of the body, and further detect the state of the vehicle occupant, such as the emotion of the vehicle occupant, by using such various devices.

[0021] The communication unit 15 is a DCM for communication connection with the outside of the vehicle 10, and enables communication processing through a communication network outside the vehicle 10. DCM is an abbreviation for Data Communication Module. The operation input unit 16 is, for example, a touch panel configured on the display screen of the display device 17 or a mechanical switch provided beside the display screen, and accepts operation input by the driver or vehicle occupants. For example, the operation switch includes a switch for switching between a manual driving mode, a driving assistance mode, and an automatic driving mode. When an operation input is received by the operation input unit 16, the ECU 12 accepts the operation input through the I / O 12z, and the ECU 12 executes control based on the operation signal of the operation input unit 16.

[0022] The display device 17 is, for example, a center information display (CID) configured with a liquid crystal display, an organic EL display, etc. The display device 17 is capable of displaying various contents under the control of the ECU 12.

[0023] The surrounding environment acquisition unit 18 is a front view camera, a side view camera, a corner view camera, a back view camera, an electronic mirror, a laser radar by LiDaR, and / or a millimeter wave radar that captures images of the surroundings of the vehicle 10. The surrounding environment acquisition unit 18 can acquire the state of the surrounding environment of the vehicle 10. The ECU 12 inputs the state of the surrounding environment acquired by the surrounding environment acquisition unit 18, for example, image information, through the I / O 12z, and stores it in the storage unit 12y. The ECU 12 and other ECUs 13 can realize various assist functions, for example, a radar cruise control function (LCC), using the state of the surrounding environment acquired by the surrounding environment acquisition unit 18. The radar cruise control function indicates a function of following the vehicle 10 traveling in front of the vehicle 10 while maintaining a certain distance. In addition, the ECU 12 and other ECUs 13 control a driving actuator related to manual driving when switched to a manual driving mode. When the ECU 12 or another ECU 13 is switched to the driving assistance mode or the automatic driving mode, it controls a driving actuator (not shown) to realize a predetermined driving assistance or automatic driving according to the level.

[0024] Other vehicle equipment 19 may include an air conditioner unit that adjusts the air conditioning in the vehicle cabin. Other vehicle equipment 19 may include entertainment equipment that includes a large-capacity storage device such as a DVD, Blu-ray disc, HDD, or semiconductor memory and provides media such as movies recorded in the storage device. Other vehicle equipment 19 may include broadcasting equipment that receives and broadcasts television waves or radio waves, and a speaker unit that outputs sound into the vehicle cabin.

[0025] The ECU 12 is configured with a microcomputer having a processor 12x such as an MCU core, various storage units 12y such as cache memory, RAM, ROM, SSD, etc., an I / O 12z, and a bus connecting these. The storage unit 12y indicates a non-transitory tangible storage medium that non-temporarily stores computer-readable programs and data. The non-transitory tangible storage medium is realized by a semiconductor memory or the like. The ECU 12 may be configured by connecting a large-capacity external storage device such as a DVD, HDD, or SSD to the outside as the storage unit 12y. The other ECUs 13 can be realized by a similar configuration.

[0026] Next, the functions of the application programs stored in the storage unit 12y will be described. The ECU 12 executes the application programs stored in the storage unit 12y by the processor 12x. When a waypoint or a destination is input by operating the operation input unit 16, the ECU 12 refers to the map information M stored in the storage unit 12y, searches for a route to the destination via the waypoint, and realizes a navigation function that provides guidance along the route. The map information M may be obtained from an external server 20.

[0027] Furthermore, the ECU 12 executes an application program to execute a navigation function for searching for a route to a destination and providing route guidance. Furthermore, the ECU 12 executes the application program to realize the functions of a calculation unit 12a, a creation unit 12b, a determination unit 12c, a notification control unit 12d, and an execution unit 12e, as shown in Fig. 2. Although the embodiment shows a form in which these functions are realized by one ECU 12, the processing capacity of the internal physical resources may be shared between the ECU 13 and other vehicle devices 19 and the ECU 12 to process the functions.

[0028] The calculation unit 12a calculates the amount of traveling power consumed while the vehicle 10 is traveling until the vehicle reaches the destination. The calculation unit 12a calculates the consumption-related power amount required to execute the functions of the in-vehicle devices (e.g., some or all of 14 to 19) used until the vehicle reaches the destination. The calculation unit 12a calculates the amount of power based on power consumption parameters that represent the power consumed inside the vehicle 10.

[0029] The power consumption parameters indicate elements that consume power in the vehicle, and include elements that consume power based on at least one of occupant information including information on the driving operation of the vehicle 10 by the driver, information on the operation of the vehicle device 19 by the vehicle occupants, and the state of the vehicle occupants, such as their emotions, the number of passengers, and the preferences of the vehicle occupants.

[0030] The power consumption parameters are parameters that change the amount of power consumption depending on various factors inside and outside the vehicle. For example, in the case of external factors, the power consumption parameters related to the amount of power consumption change depending on factors such as weather, detours due to road closures on the route, changes in load weight, and driver changes. For example, if the weather gets hotter, the power consumption of the air conditioner increases. Also, if it rains, the frequency of use of the wipers increases, and power consumption increases. If a route is set and a detour is taken due to a road closure, the power consumption also changes depending on the accumulated distance and the gradient. Also, if the driver is changed along the way, the power consumption also changes depending on the driving habits of the driver. In the case of internal factors, the change in power consumption due to the aging of various parts inside the vehicle can be cited.

[0031] <<Crew information description>> Here, the occupant information will be described. The occupant information indicates the state of the vehicle occupant such as emotions monitored by the occupant detection unit 14, and indicates the preference setting state and priority of the vehicle occupant. The preference setting state of the vehicle occupant indicates setting information and history information input in advance by operation input unit 16 before starting to drive the vehicle 10 or while driving. The preference setting state of the vehicle occupant does not need to be personalized for each individual with respect to data such as the attributes, behavior, and operation history of the vehicle occupant, and may be set for each group such as the owner of the vehicle 10 or a family member.

[0032] The server 20 is capable of communicating with the multiple vehicles 10 via the communication units 15, and receives and stores data on preferences set in each vehicle 10 from the communication units 15 of the multiple vehicles 10. The server 20 learns in advance operation input information input by the operation input units 16 stored in the memory units 12y of the multiple vehicles 10, sets priority of preferences in order of frequency of setting, and sets this information as occupant information.

[0033] For example, when the server 20 learns information transmitted from a large number of vehicles 10 and learns that "the owner of this vehicle 10 often watches movies on the highway," the server 20 notifies the ECU 12 of the vehicle 10 of the information. The ECU 12 stores the information as occupant information in the storage unit 12y. Note that a part or all of the processing contents of the server 20 may be performed by the ECU 12 of each vehicle 10. In the above, the preference priorities are set as occupant information by relatively comparing a large number of vehicle occupants, but the present invention is not limited to this. For example, the ECU 12 may set preference priorities in descending order of frequency of setting based on the results of learning the vehicle occupants individually, and set the information as occupant information.

[0034] <<Explanation of how to calculate the amount of electric power used for driving>> Next, a method for calculating the amount of electric power for driving will be described. When the driver starts manual driving of the vehicle 10, the vehicle 10 starts to drive, and at this time, the degree of decrease in the remaining amount of electric power stored in the battery 11 changes depending on the degree of depression of the accelerator and the brake by the driver. The degree of decrease in the remaining amount of electric power stored in the battery 11 also changes depending on the riding state of the vehicle occupants and the increase or decrease in the number of passengers.

[0035] In addition, vehicle information related to driving assistance such as a normal mode for normal driving with a good balance of fuel efficiency, quietness, and maneuverability, a power mode for accelerating the response to the accelerator operation and realizing powerful acceleration, and an eco-drive mode for making the driving force gentler in response to the accelerator operation and suppressing the operation of the air conditioner to emphasize energy saving is set in the ECU 12 of the vehicle 10. In addition, information on the current devices inside the vehicle 10, such as which devices are operating, whether or not the mobile terminal 8 is connected to the charging port and charging, the set temperature of the air conditioner and the associated power consumption, is set as vehicle information in the ECU 12 of the vehicle 10.

[0036] Based on this type of vehicle information and the gradient of the planned travel route searched for until the destination is reached, the degree of decrease in the remaining power amount of the battery 11 until the destination is reached changes. The calculation unit 12a calculates the amount of power for travel until the destination is reached based on such vehicle information and power consumption parameters such as the travel conditions of the planned travel route.

[0037] Furthermore, whether the vehicle is being driven manually or automatically, the vehicle occupant may use the temperature control function of the air conditioner, entertainment equipment, or broadcasting equipment based on their preferences through the other vehicle devices 19. For this reason, the calculation unit 12a calculates the consumption-related power amount required to reach the destination based on the operation information of the in-vehicle devices (e.g., 14 to 19) including such other vehicle devices 19, operation input information, and power consumption parameters based on the preferences of the vehicle occupant.

[0038] The creation unit 12b is provided for creating power usage plans K1, K2 for traveling to a destination based on the traveling power amount and the consumption-related power amount. The determination unit 12c is provided for determining whether or not the use of the current power usage plan K2 is appropriate, for example, whether or not it is impossible to continue, based on the power consumption parameters.

[0039] If the determination unit 12c determines that the power usage plan K2 is not appropriate, for example that it is not sustainable, the creation unit 12b creates an update power usage plan K2a that is different from the current power usage plan K2. The notification control unit 12d is provided for controlling notification of the power usage plans K1, K2 and / or the update power usage plan K2a to the vehicle occupants. The execution unit 12e has a function of executing the power usage plan K1, K2 or K2a after confirming with the vehicle occupant as necessary.

[0040] A specific example of the function will be described below with reference to a flowchart. When the driver turns on the ignition switch or power switch of the vehicle 10, power is supplied from the battery 11 to the vehicle 10, and the vehicle devices 19 such as the ECU 12 are started. After starting up, the ECU 12 executes the process shown in FIG.

[0041] When the driver inputs a destination by operating the operation input unit 16 and performs an operation related to driving, the ECUs 12 and 13 start driving control. As shown in Fig. 3, the ECU 12 acquires the state of the surrounding environment by the surrounding environment acquisition unit 18 in S11, and acquires information on the destination input by the operation input unit 16 in S12.

[0042] In S13, the ECU 12 acquires occupant information and vehicle information from the other ECUs 13, the other vehicle devices 19, and the occupant detection unit 14. As described above, the occupant information indicates information on the driving operation of the vehicle 10 by the driver, information on the operation of the in-vehicle devices by the vehicle occupants, the riding state of the vehicle occupants, the number of occupants, the setting status of the preferences of the vehicle occupants, etc.

[0043] In S14, the calculation unit 12a of the ECU 12 considers the occupant information and the vehicle information as power consumption parameters, and calculates the amount of power required from the current location to the destination based on the power consumption parameters. The creation unit 12b of the ECU 12 creates a power usage plan K1 in S15. The power usage plan K1 is obtained in a chronological order by integrating the power consumption amounts calculated by the calculation unit 12a over the planned travel route to the destination, and subtracting this from the current remaining charge of the battery 11.

[0044] As shown in Fig. 4, consider the case where power usage plan K1 from the current location to the destination has been created. ECU 12 calculates the total amount of power consumption assuming that the current power usage plan K1 is implemented until the destination is reached, and determines whether there is a margin of power equal to or greater than a predetermined remaining amount E that allows for a margin of power. If ECU 12 determines that there is a margin of power equal to or greater than the remaining amount E, notification control unit 12d of ECU 12 notifies and proposes the current power usage plan K1 to the vehicle occupant in S15, and controls the notification to encourage the implementation of the current power usage plan K1.

[0045] 4, for example, notification control unit 12d displays and proposes current power usage plan K1 on the display screen of display device 17, and notifies that if current power usage plan K1 is implemented, there will be a remaining amount exceeding a predetermined remaining amount E that anticipates a margin power amount until reaching the destination. In this way, notification control unit 12d can control notifications to encourage implementation of current power usage plan K1.

[0046] Thereafter, the ECU 12 determines in S16 whether or not the power consumption parameters have been updated. If the power consumption parameters have not been updated in S16, the ECU 12 determines NO in S16 and applies the proposed power usage plan K1 in S18. The ECU 12 executes control related to the power usage plan K1 by the execution unit 12e.

[0047] For example, if a vehicle occupant such as a driver issues an instruction to start using the air conditioner unit together with the entertainment device while the vehicle 10 is stopped before starting to drive, it is expected that a large amount of power will be consumed by the time the vehicle reaches the destination. At this time, the ECU 12 calculates the amount of power consumption using the calculation unit 12a. In S15, the ECU 12 creates a power usage plan K2 based on the calculation result of the calculation unit 12a. For example, upon receiving an instruction to start using the vehicle device 19, the ECU 12 determines in S16 that the power consumption parameters have been updated, and determines YES in S16. In S17, the ECU 12 determines whether the current power usage plan K2 is appropriate using the function of the determination unit 12c.

[0048] If the air conditioner unit continues to be used together with the entertainment device in the vehicle while driving from the current location to the destination, a large amount of power continues to be consumed. Therefore, as a result of the calculation of the amount of power by the calculation unit 12a, the amount of power in the battery 11 may reach a predetermined remaining amount E at the midpoint T2 between the current location and the destination, as shown in the power usage plan K2 indicated by the dashed line in Fig. 5. In this case, the ECU 12 determines, by the function of the determination unit 12c, that the current power usage plan K2 is not appropriate. In other words, the ECU 12 determines, by the function of the determination unit 12c, that the use of the current power usage plan K2 is not appropriate if the amount of power exceeds a predetermined standard set from the viewpoint of security or safety.

[0049] If the determination unit 12c of the ECU 12 determines that the plan is inappropriate and cannot be continued, then the answer is NO in S17, and the creation unit 12b of the ECU 12 creates an update power usage plan K2a in S19 that is different from the current power usage plan K2.

[0050] For example, when the creation unit 12b creates the update power usage plan K2a shown by the solid line in Fig. 5, the notification control unit 12d notifies and proposes the update power usage plan K2a on the display screen of the display device 17 in S19. The notification control unit 12d may notify a suggestion such as "You will consume more power than expected. You can use it up to point T1 (place name, etc.), but if you continue traveling the vehicle 10, how about refraining from using the air conditioner until you reach the destination?" or may notify a suggestion such as "How about reducing power usage." If the vehicle occupant accepts the notification and proposal by operating the operation input unit 16 in S20 as a result of the notification and proposal by the notification control unit 12d, the update power usage plan K2a is applied in S18b. The ECU 12 executes control of the update power usage plan K2a by the execution unit 12e.

[0051] These processes are also executed while the vehicle 10 is traveling, as shown in Figures 6 and 7. For example, if an additional operation input is made by the vehicle occupant while the vehicle 10 is traveling, the vehicle 10 will start consuming more power than previously planned while traveling. In such a case, the processes are executed in the same manner.

[0052] The ECU 12 acquires occupant information and vehicle information in S21 even while the vehicle 10 is traveling, and acquires the state of the surrounding environment in S22. The ECU 12 determines in S23 whether or not the power consumption parameters have been updated.

[0053] While the vehicle 10 is traveling toward the destination, a power usage plan (here, K1, for example) has already been created. If there is no active input of a change to the power usage plan K1 by the vehicle occupant, but an action that is presumed to be a change, i.e., an action of consuming large amounts of power, is performed, it is determined in S23 that the power consumption parameters have been updated.

[0054] For example, as shown in Fig. 7, the amount of power stored in the battery 11 gradually decreases while the vehicle 10 is traveling from the departure point. If the vehicle occupant starts watching a movie while the vehicle 10 is traveling and resets the air conditioner to a stronger setting, the amount of power consumed increases. In this case, the rate at which the amount of stored power in the battery 11 decreases increases.

[0055] The ECU 12 creates a power usage plan K3 in S24 on the condition that the power consumption parameters have been updated, referring to the current power usage plan K3. The ECU 12 determines in S25 whether the current power usage plan K3 can be continued and used.

[0056] For example, the ECU 12 determines that the current power usage plan K3 will reach a predetermined remaining amount E before the vehicle reaches the destination, and determines that the plan cannot be continued and is not appropriate. The ECU 12 creates an updated power usage plan K4 in S26 and suggests that the plan be implemented by the vehicle occupant.

[0057] In S26, the ECU 12 may control the notification of a suggestion for an updated power usage plan K4 that will reduce the rate of decrease in the remaining power of the battery 11 along with a message such as "You can watch movies until you reach your destination. Perhaps you could try lowering the temperature setting on the air conditioner.", or may control the notification of a suggestion such as "Maybe you could try reducing your power usage."

[0058] If the vehicle occupant agrees in S27, ECU 12 applies the update power usage plan K4 in S28. If the vehicle occupant agrees by operating input on operation input unit 16 as a result of the notification and proposal by notification control unit 12d, ECU 12 applies the update power usage plan K4 in S28b. ECU 12 executes the control of the update power usage plan K4 using the function of execution unit 12e.

[0059] <<About preference priorities>> The priority of the preferences of the vehicle occupants may be set in advance in the memory unit 12y of the ECU 12 by the operation input unit 16. If the priority of watching a movie is high and the priority of adjusting the air conditioning by the air conditioner is low and set in the memory unit 12y, the ECU 12 may suggest to the vehicle occupants to give priority to watching a movie by controlling notification of a message such as "You can watch a movie until you reach your destination. How about lowering the temperature setting of the air conditioner?" in S26.

[0060] Conversely, if the priority of the air conditioning adjustment of the air conditioner is high and the priority of watching a movie is low and are set in the memory unit 12y, the ECU 12 may suggest to the vehicle occupant in S26 that the temperature setting of the air conditioner be prioritized, such as "You can enable the temperature setting of the air conditioner until you reach the destination, but how about refraining from watching a movie?" It is desirable for the ECU 12 to suggest and notify the vehicle occupant of the preferences based on the priorities set in this way.

[0061] Furthermore, if ECU 12 determines that the current power usage plan K3 will reach a predetermined remaining amount E before the destination is reached and thus is not suitable and cannot be continued, an updated power usage plan K4 may be created to suppress use of the air conditioner that regulates the environment inside vehicle 10. When regulating the environment inside vehicle 10, an updated power usage plan K4 may be created and executed by detecting an unoccupied seat using occupant detection unit 14 and adjusting the output of the air conditioning for that seat. In this case, the updated power usage plan K4 may be notified to a vehicle occupant, or may be automatically executed by execution unit 12e without obtaining the consent of the vehicle occupant in S27.

[0062] Furthermore, if a temperature adjustment function is provided in the seat in which the vehicle occupant sits, the ECU 12 may create and execute the updated power usage plan K4 so as to control the output of the temperature adjustment function and adjust the temperature sensation of a part of the body of the vehicle occupant to adjust the power usage. The ECU 12 may create and execute the updated power usage plan K4 so as to adjust the power usage by adjusting the output of the air conditioning and blowing air onto a limited part of the body of the vehicle occupant. In this case, the execution unit 12e may automatically execute the updated power usage plan K4 without controlling notification to the vehicle occupant or obtaining the consent of the vehicle occupant in S27.

[0063] <Example> The ECU 12 can obtain temperature information in the vehicle cabin using a temperature sensor. The ECU 12 may determine that the amount of power in the battery 11 is low and inappropriate when the vehicle occupants feel that the inside of the vehicle is relatively cold, such as in winter. The ECU 12 may create and propose an updated power usage plan K4 in which the heating function of the air conditioner and / or the seat heater function are stopped to save power, and may execute the proposed plan if consent is obtained. The ECU 12 may also create an updated power usage plan K4 in which the target temperature setting of the heating function of the air conditioner is gradually lowered to save power.

[0064] It may be determined that the amount of power required to reach the destination can be secured by operating other vehicle equipment 19, such as entertainment equipment, instead of stopping the heating function of the air conditioning and / or the seat heater function. In this case, an updated power usage plan K4 for when the entertainment equipment is operated may be created and proposed, and may be executed if consent is obtained. The updated power usage plan K4 may be executed by the execution unit 12e without obtaining consent from the vehicle occupant.

[0065] Conversely, if there is a relatively large amount of power remaining in battery 11 before reaching the destination, it may be determined that the vehicle occupants will feel relatively cold inside the vehicle in winter or the like. In this case, the excess power can be used to increase the air conditioning heating function and / or the seat heater function. For this reason, ECU 12 creates and proposes an updated power usage plan K4 in which the amount of power consumed by the air conditioning heating function and / or the seat heater function is increased, and executes the updated power usage plan if consent is obtained. The updated power usage plan K4 may be executed by execution unit 12e without obtaining consent from the vehicle occupants.

[0066] For example, in the summer when the vehicle occupants feel that the inside of the vehicle is relatively hot, it may be determined that the amount of power in the battery 11 is low and inappropriate. In this case, an updated power usage plan K4 in which the cooling function of the air conditioner is stopped to save power may be created and proposed, and if consent is obtained, the plan may be executed. An updated power usage plan K4 in which the target temperature setting of the cooling function of the air conditioner is gradually increased to save power may also be created.

[0067] The ECU 12 may determine that the amount of power required to reach the destination can be secured by operating other vehicle equipment 19, such as an entertainment device, instead of stopping the cooling function of the air conditioner. In this case, the ECU 12 creates and proposes an updated power usage plan K4 for when the entertainment device is operated, and executes the plan if consent is obtained. The updated power usage plan K4 may be executed by the execution unit 12e without obtaining consent from the vehicle occupant.

[0068] Conversely, if there is a relatively large amount of power remaining in battery 11 before reaching the destination, it may be determined that the vehicle occupants will feel relatively hot inside the vehicle in summer or the like. By using the surplus power, ECU 12 can strengthen the cooling function of the air conditioner, for example by lowering the target set temperature. For this reason, ECU 12 may create and propose an updated power usage plan K4 in which the amount of power consumed by the cooling function of the air conditioner is increased, and execute the plan if consent is obtained. The updated power usage plan K4 may be executed by execution unit 12e without obtaining consent from the vehicle occupants.

[0069] According to this embodiment, the update power usage plan (e.g., K4) is updated and executed by execution unit 12e without waiting for a decision by an occupant of vehicle 10. At this time, notification control unit 12d may notify how the power usage plan (e.g., K3 → K4) is updated so that the change between the power usage plan before and after the update (e.g., K3 → K4) can be understood.

[0070] <Variation 1> Unlike the above-mentioned case where there is no margin in the amount of power, as a result of calculating the total amount of power consumption, ECU 12 may determine that the current power usage plan T5 has a much larger margin than the predetermined remaining amount E, as shown in Fig. 8. In such a case, ECU 12 may create an update power usage plan T6 so as to increase the amount of power consumption based on the preferences of the vehicle occupant in S19 of Fig. 3 or S26 of Fig. 6. In this case, notification control unit 12d may perform notification control so as to propose a power usage plan related to the preferences of the vehicle occupant in accordance with the update power usage plan T6.

[0071] For example, as described above, the ECU 12 may refer to the occupant information from the storage unit 12y as the preferences of the vehicle occupant and may have previously learned that "the owner of this vehicle 10 often watches movies on the highway." In this case, the notification control unit 12d of the ECU 12 may create and notify an updated power usage plan T6 for watching a movie along with a message such as "There is a margin of power. How about watching a movie?". The ECU 12 may apply this updated power usage plan T6 if the vehicle occupant agrees. In this case, the ECU 12 controls the display device 17 to display the movie content using the function of the execution unit 12e.

[0072] <Variation 2> For example, as shown in FIG. 9A, when the vehicle occupant starts to operate the vehicle 10, the ECU 12 creates power usage plans K8 and K8a that consume more power than the initial power usage plan K7. In this case, the ECU 12 may use the power usage plan K8 that reflects the needs of the vehicle occupant up to a point T3 on the driving route, and may suggest to use the power usage plan K8a that saves more power than the power usage plan K8 from the middle of the driving of the vehicle 10. A specific example will be described. For example, it is assumed that the ECU 12 has caught traffic congestion information on the planned driving route of the vehicle 10 at the time of the operation by the vehicle occupant. During this time, the ECU 12 determines that there is a high possibility that the vehicle occupant will use various assist functions (e.g., radar cruise control function (LCC)) related to the driving operation of the vehicle 10 during traffic congestion, or an entertainment device for watching movies to enjoy the boring traffic congestion time.

[0073] If the ECU 12 predicts that the congestion will be resolved at a waypoint T3 on the planned travel route as time passes, the ECU 12 can predict that the vehicle occupants' power usage needs, in this case, the use of assist functions such as a radar cruise control function and / or entertainment devices, will decrease after the time when the congestion is resolved at the waypoint T3. In this case, the ECU 12 may create and propose a power usage plan K8a that limits the use of assist functions and entertainment devices from the waypoint T3 on the planned travel route. This allows the needs of the vehicle occupants to be reflected as much as possible.

[0074] As described above, according to this embodiment, ECU 12 calculates the amount of power required to travel to the destination by calculating the amount of power consumption for purposes unrelated to travel as well as the amount of power required to travel to the destination. ECU 12 then determines whether the current power usage plan (e.g., K1, K2) is appropriate on the condition that the power consumption parameters were updated before it became impossible to travel to the destination, and if it is determined that the current power usage plan is not appropriate, creates an updated power usage plan (e.g., K2a).

[0075] Therefore, even if an event occurs that requires a large amount of power consumption when the power usage limit is reached, the system can consume power in response to this event. In this way, the amount of power in the battery 11 can be appropriately managed while maintaining the remaining amount E or more until the destination is reached.

[0076] If the ECU 12 simply makes suggestions to satisfy the needs of the vehicle occupant, the remaining power of the battery 11 may become insufficient. Therefore, the ECU 12 creates the updated power usage plans K2a, K4, K6 based on a number of conditions, for example, operation input information and the state of the vehicle occupant. This enables power management that meets the steadily changing needs of the vehicle occupant. By processing in this manner, it is possible to actively propose power management that meets the needs to the vehicle occupant. By creating, notifying, and proposing the updated power usage plans K2a, K4, K6, etc., the vehicle occupant can be aware of power management even before or during driving.

[0077] The ECU 12 turns on / off in-vehicle devices (e.g., entertainment devices, broadcasting devices) that can operate until the destination based on the priority of the preferences, or suggests parameters for parameter-configurable in-vehicle devices (e.g., air conditioning settings of an air conditioner), thereby meeting the needs of the vehicle occupants.

[0078] <Third Modification of the First Embodiment> FIG. 9B shows a partial modification of FIG. 3. The ECU 12 creates and proposes the update power usage plan K2a in S19, but if the vehicle occupant does not agree in S20, the ECU 12 creates the update power usage plan K2a again in S19. However, if the ECU 12 proposes the update power usage plan K2a to the vehicle occupant a predetermined number of times in S20b but there is no response of acceptance, the ECU 12 may determine YES in S20b and execute the update power usage plan K2a by the execution unit 12e regardless of the judgment of the vehicle occupant. In other words, if communication with the vehicle occupant does not go well, the plan may be forcibly executed. In this example, the process while the vehicle is stopped is shown, but the process of FIG. 6 can be applied to the vehicle while it is moving in the same manner.

[0079] <Fourth Modification of the First Embodiment> FIG. 9C shows a partial modification of FIG. 3. In S17, the ECU 12 judges whether the current power usage plan K1 is appropriate. At this time, if it is determined that the destination cannot be reached due to a lack of driving power or fuel, or that the vehicle will stop at an undesired parking location due to a lack of driving power or fuel, then it is determined that the use of the current power usage plan K1 is inappropriate. For example, when the vehicle is caught in traffic while driving on a highway, or when a route is set through the mountains, it is determined that there is no charging facility and the necessary charging cannot be performed. In this case, it is advisable to display a message that "there is a problem with the current power usage plan."

[0080] The ECU 12 creates and proposes the updated power usage plan K2a in S19, but if the vehicle occupant does not agree in S20, the updated power usage plan K2a will be created again in S19. If the occupant does not agree, a new plan may be proposed by the occupant (YES in S20c). For example, the occupant may request to continue the plan because the current power usage plan K1 is comfortable. For example, the updated power usage plan K2a created in S19 proposed to change the air conditioner temperature setting higher, but the occupant may wish to maintain the air conditioner temperature setting low.

[0081] In S20d, the ECU 12 determines whether the proposed update power usage plan K2a is appropriate. If the ECU 12 determines that the proposed update power usage plan K2a is appropriate, the ECU 12 can apply the proposed update power usage plan K2a and put it into execution. If the proposed update power usage plan K2a is not appropriate, the ECU 12 determines in S20e whether the process has been repeated a predetermined number of times, and if the process is less than the predetermined number of times, the process returns to S19 to create the update power usage plan K2a again, and the processes of S20, S20c, and S20d are repeated.

[0082] If an inappropriate suggestion is made to the vehicle occupant a predetermined number of times in S20e, ECU 12 may determine YES in S20e and forcibly execute the updated power usage plan K2a created in S19 regardless of the judgment of the vehicle occupant. In other words, if communication with the vehicle occupant is not going well, the updated power usage plan K2a created may be forcibly executed. In this example, the processing while the vehicle is stopped is shown, but the processing of FIG. 6 can be similarly applied while the vehicle is moving.

[0083] <How to change the power usage plan when resetting the destination, route, etc.> The destination of the navigation function may be reset based on the driver's instructions, or a waypoint may be set for shopping, resting, etc. In addition, the driver may choose to spend time shopping or resting without setting a waypoint, in response to a change of driver's will. In this case, the route may be changed while the vehicle is traveling. This may affect the desired time to arrive at the final point of the destination earlier or later. If the destination or waypoint is changed, the same process can be realized by performing the process of FIG. 3 or FIG. 6 again.

[0084] Second embodiment The second embodiment will be described with reference to Fig. 10. In this embodiment, as shown in S31 and S32 in Fig. 10, a case will be described in which the ECU 12 detects that the operation input unit 16 has switched from manual driving to automatic driving.

[0085] When ECU 12 detects that the vehicle has been switched to autonomous driving, ECU 12 controls notification of the current power usage plan (e.g., T5 in FIG. 8) and the current power usage status in S33. ECU 12 controls notification to inquire of the vehicle occupant about whether or not there is a change to the current power usage plan T5 in S34. For example, during autonomous driving in an autonomous driving mode at or above a predetermined level, the driver does not need to concentrate on driving.

[0086] Vehicle occupants have more time to spend in the vehicle cabin and more opportunities to enjoy entertainment. For this reason, the ECU 12 performs notification control in S35 to ask about the necessity of changing the current power usage plan T5 along with the current power usage plan T5. In this case, if the ECU 12 determines in S35 that a change is necessary, it may create an updated power usage plan T6 in S36 and perform notification control with the updated power usage plan T6 and a message such as "How about watching a movie during automatic driving?". If the ECU 12 determines in S35 that a change is not necessary, the ECU 12 applies the power usage plan T5 as is in S37.

[0087] If ECU 12 obtains consent from the vehicle occupant in S36b, it applies the update power usage plan T6 in S37b. If consent from the vehicle occupant is not obtained, the process returns to S36 and the creation of the update power usage plan is repeated. If there is no response from the vehicle occupant, the update power usage plan may be applied in S37b without obtaining consent. Here, ECU 12 may automatically control display by the function of execution unit 12e to display the movie content on display device 17 as necessary.

[0088] During autonomous driving, there are many situations where vehicle occupants may want to consume electricity. According to this embodiment, it is possible to manage power consumption in a concentrated manner during autonomous driving, etc. Furthermore, it is possible to respond to the needs of vehicle occupants at any time while the vehicle 10 is traveling.

[0089] Third embodiment The third embodiment will be described with reference to Fig. 11 to Fig. 14. When executing a navigation function after a destination is inputted, the ECU 12 processes and displays the contents of the map information M together with a current position mark of the vehicle 10 on the display screen of the display device 17, as shown in the upper part of Fig. 11.

[0090] As shown in Fig. 12, while vehicle 10 is traveling, ECU 12 determines in S41 whether or not the current power usage plan (for example, K3 in Fig. 7) is appropriate. If ECU 12 determines that current power usage plan K3 cannot be continued and is inappropriate, ECU 12 creates an update power usage plan K4 in S42.

[0091] In S43, the ECU 12 determines whether or not the content is being displayed on the display screen of the display device 17. If the content is already being displayed, the notification control unit 12d of the ECU 12 may display the impossibility of continuation information and the reason information on the display screen of the display device 17, superimposed on the map information M which is already being displayed in S44.

[0092] 11, the ECU 12 displays the impossibility of continuation information "You cannot reach the destination with the current power usage plan" and the reason information "It appears that the air conditioner is using too much power" on the display device 17. The ECU 12 may display suggestion information such as "How about turning off the air conditioner?" overlaid on the above information.

[0093] 13, the notification control unit 12d of the ECU 12 may graph the current power usage plan K3 and the updated power usage plan K4, and may display the graph by overlaying a diagram P on map information M as uncontinuable information on a part of the display screen of the display device 17. Here, an example is shown in which the diagram P is overlaid on map information M, but the graph may also be displayed by overlaying it on peripheral camera information capturing an image of the periphery of the vehicle 10, or on various types of video information such as movies and television broadcasts.

[0094] Conversely, when ECU 12 determines in S43 of Fig. 12 that no content is being displayed on display device 17, the process proceeds to S45. In S45, ECU 12 controls display device 17 to display non-continuance information indicating that the current power usage plan (e.g., K3 in Fig. 7) cannot be continued, and reason information indicating the reason why it is not possible to continue. At this time, the information may be displayed as text or a graph may be drawn, and ECU 12 may display the non-continuance information and reason information on the entire display screen of display device 17 as shown in Fig. 14.

[0095] Furthermore, the notification control unit 12d of the ECU 12 may display the result on a part of the display screen of the display device 17, or may display only the result of whether or not the current power usage plan (for example, K3 in FIG. 7) can be continued. Furthermore, the notification control unit 12d of the ECU 12 may change the display mode depending on the remaining amount of power in the battery 11 when the destination is reached. The lower the remaining amount of power when the destination is reached, the stronger the warning color or warning color may be used to call attention.

[0096] (Fourth embodiment) The fourth embodiment will be described with reference to Fig. 15 to Fig. 18. When executing a navigation function after a destination is inputted, the ECU 12 performs processing to display the contents of the map information M together with a current position mark of the vehicle 10 on the display screen of the display device 17, as shown in the upper part of Fig. 15.

[0097] As shown in Fig. 16, while vehicle 10 is traveling, ECU 12 determines in S41 whether or not the current power usage plan (here, for example, K3 in Fig. 7) is appropriate. If ECU 12 determines that current power usage plan K3 cannot be continued and is inappropriate, then ECU 12 creates an updated power usage plan K4 in S42.

[0098] In S43, the ECU 12 determines whether or not the content is being displayed on the display screen of the display device 17. If the content is already being displayed, the notification control unit 12d of the ECU 12 changes the display layout of the already-displayed information in S44a, and displays the impossibility of continuation information and the reason information in an area different from the layout area of ​​the already-displayed information in S44b.

[0099] For example, consider a case where map information M is displayed on the entire display screen of the display device 17 together with a current position mark of the vehicle 10, as shown in the upper part of Fig. 15. In this case, the ECU 12 may cut out a part of the left half of the map information M and leave it displayed, leaving the cut-out part blank, and utilize this blank area to display the impossibility of continuation information and reason information on the right half of the display screen.

[0100] Alternatively, as shown in the lower part of Fig. 17, the ECU 12 may reduce the overall scale of the map information M and use the resulting free space to display the non-continuation information and the reason information on the display screen. Alternatively, as shown in the lower part of Fig. 18, the ECU 12 may erase the entire map information M and use the resulting free space to display the non-continuation information and the reason information on the entire display screen. This makes it possible to warn vehicle occupants to be aware of power consumption in the vehicle cabin.

[0101] A modified example of the proposal for changing the power usage plan will be described. As described above, it may be bothersome for the user to propose a change every time a specific condition is met. For this reason, it is preferable to make the proposal using the current driving situation of the vehicle occupant and history information of past operation inputs. This makes the user feel more happy than bothered. Operation input information of the vehicle occupant in response to the proposal may be accumulated as learning data, and it may be determined whether or not to make a proposal based on the learning data. It is preferable to increase the frequency of proposals when a positive response to the proposal is received, and to decrease the frequency of proposals when a negative response is received.

[0102] Fifth embodiment The fifth embodiment will be described with reference to Fig. 19. When displaying various pieces of information, the notification control unit 12d of the ECU 12 may set an info area IN in a part of the display screen of the display device 17 as shown in the upper part of Fig. 19. It is preferable to display information that does not require any operation by the occupant in this info area IN. For example, it is preferable to display notification information such as "You have received a message" when an email is received for the occupant, or general news information, in a horizontally flowing manner.

[0103] When some kind of emergency information occurs, the notification control unit 12d of the ECU 12 may display a pop-up if the information is highly urgent or if an operation by the occupant is required (for example, in the above-described embodiment, whether or not a change can be made to the power usage plan (e.g., from K1 to K2a)). In this case, as shown in the lower part of FIG. 19, the notification control unit 12d of the ECU 12 may display the emergency information in a embossed manner to make it stand out, or may display it together with an icon indicating a warning such as an exclamation mark, and may also notify the driver by accompanying the emergency information with a sound to call attention.

[0104] The present disclosure is not limited to the above-described embodiment, and can be implemented in various modifications and can be applied to various embodiments without departing from the gist of the present disclosure. The method by the ECUs 12 and 13 described in the present disclosure may be realized by a dedicated computer provided by configuring a processor and a memory programmed to execute one or more functions embodied in a computer program.
