  However, since the system shown in Patent Document 1 uses a dedicated gain changer for changing the control gain, the gain changer tends to be expensive. In addition, in order for the driver of the vehicle to adjust the control gain with the gain changer, some specialized knowledge is required. Furthermore, it is difficult to efficiently and simply set the optimal control gain for the driver. As a result, it is difficult for the driver to easily use the system.

  On the other hand, in the system found in Patent Document 2, the control specification changing device performs wireless communication between a server for holding data for changing the vehicle specification and the control specification changing device for the vehicle. Therefore, the vehicle control specifications can be easily changed.

  However, in the thing of patent document 2, in order for the control specification change apparatus mounted in the vehicle to perform radio | wireless communication with a server, a dedicated communication line is needed.

  For this reason, the area where the control specification changing device and the server can perform wireless communication (the area where the vehicle is present), and thus the area where the system for changing the control specification can be used is likely to be limited to a narrow area. In addition, since it is necessary to mount the communication device for the dedicated communication line on the vehicle, it is difficult to reduce the cost of the system and to spread it.

  The present invention has been made in view of such a background, and is capable of appropriately realizing changing a vehicle control specification with a versatile and simple system configuration regardless of a vehicle existing area. It aims at providing a specification change system and vehicles.

  A predetermined application program for changing the control specifications of the vehicle 10 (hereinafter referred to as a control specification changing application) is installed in the portable terminal 2 in advance. And the portable terminal 2 changes the control specification of the vehicle 10 by a function realized by the control specification changing application and the hardware configuration (control circuit unit, memory, communication device, etc.) of the portable terminal 2. It is possible to communicate with the server 100 that provides the specification change data via the public communication network 3.

  In this case, the mobile terminal 2 can communicate with the server 100 by a predetermined operation of the mobile terminal 2 or in response to a command from the vehicle control device 11.

  The server 100 stores a plurality of types of specification change data for changing the control specifications of various vehicles including the vehicle 10. The specification change data is constituted by one or both of a control program and control reference data, for example. The reference data for control is configured by parameter values such as target values, threshold values, control gains, etc. used for control processing, or map data or table data.

  The portable terminal 2 has a function of acquiring (downloading) specification change data usable in the vehicle 10 from the server 100 through communication with the server 100.

  The vehicle control device 11 is configured by an electronic circuit unit including a CPU, a RAM, a ROM, an interface circuit, and the like. The vehicle control device 11 may be composed of a plurality of electronic circuit units that can communicate with each other.

  The vehicle control device 11 includes a communication device 21 for performing wireless communication by wired communication or Bluetooth or the like with the portable terminal 2 in a state where the portable terminal 2 is disposed in the vehicle 10. Via the mobile terminal 2.

  More specifically, the state in which the mobile terminal 2 is arranged in the vehicle 10 means that the vehicle 10 is within an area where the mobile terminal 2 can communicate with the vehicle control apparatus 11 (a peripheral area of the vehicle control apparatus 11). It is the state arrange | positioned in the inside (vehicle interior etc.) or the periphery of the vehicle 10. FIG.

  Further, the vehicle control device 11 includes a standard specification storage unit 22 in which standard control data for the vehicle 10 (data configured by a control program or control reference data in the standard specification) is stored and held in advance. A plurality of change specification storage units 23, 23,... For storing and holding specification change data acquired from the server 100. These storage units 22 and 23 are configured by a nonvolatile memory such as an EEPROM.

  In addition, the vehicle control device 11 includes a specification change control processing unit 24 that executes a process related to a change in the control specification of the vehicle 10 as a function realized by a program or hardware configuration that is mounted in advance in the ROM, and the storage unit 22. , 23, and a vehicle control process execution unit 25 that executes the control process with the control specification defined by the data using the data stored and held in any of the data.

  The specification change control processing unit 24 includes, as its function, a data acquisition unit 24a that executes a process of acquiring the specification change data acquired by the mobile terminal 2 from the mobile terminal 2, and the specification change data acquired from the mobile terminal 2. Includes a data determination unit 24b that executes a process for determining whether or not the data is normal data, and a specification switching processing unit 24c that executes a process for switching (changing) the control specifications of the vehicle 10.

  Next, a process for acquiring the specification change data of the vehicle 10 by the vehicle control device 11 of the vehicle 10 will be described.

  In a state where the mobile terminal 2 is arranged in the vehicle interior of the vehicle 10 and the mobile terminal 2 can communicate with the vehicle control device 11 by wire or wirelessly, the specification change control processing unit 24 of the vehicle control device 11 The process shown in the flowchart of FIG. 2 is executed. This processing includes the processing of the data acquisition unit 24a and the data determination unit 24b of the specification change control processing unit 24.

  In STEP 1, the specification change control processing unit 24 determines whether or not there is a request for acquiring specification change data.

  In the present embodiment, for example, when acquisition of specification change data is instructed by a screen operation of the display device 15 or voice input to the microphone 16, or the specification change data acquisition process is interrupted halfway. When the flag is stored and held in a nonvolatile memory such as an EEPROM of the vehicle control device 11, the determination result of STEP1 becomes affirmative.

  Here, in a state in which the mobile terminal 2 can communicate with the vehicle control device 11, the vehicle control device 11 has a first operation unit for instructing the screen of the display device 15 to acquire control specification change data. 15a, the operation unit related to the change of the control specification such as the second operation unit 15b for instructing the switching of the control specification is displayed.

  Then, when the driver of the vehicle 10 performs a touch operation on the first operation unit 15 a of the display device 15, the specification change control processing unit 24 is instructed to acquire specification change data. Alternatively, when the driver of the vehicle 10 inputs a sound for instructing acquisition of the specification change data to the microphone 16, the specification change control processing unit 24 is instructed to acquire the specification change data. In these cases, the determination result of STEP1 becomes affirmative.

  In addition, the specification change data acquisition process may be interrupted in the middle due to, for example, turning off the accessory power supply of the vehicle 10 while the specification change control processing unit 24 is acquiring the specification change data. In such a case, the specification change control processing unit 24 stores and holds in the nonvolatile memory a flag indicating that the specification change data acquisition process has been interrupted.

  In this case, after the interruption, the determination result in STEP 1 becomes affirmative in a state where communication between the mobile terminal 2 and the vehicle control device 11 is possible.

  When the determination result of STEP1 is negative, the specification change control processing unit 24 sequentially repeats the determination process of STEP1 until the determination result of STEP1 becomes affirmative. If the determination result in STEP 1 is affirmative, the specification change control processing unit 24 then communicates with the mobile terminal 2 in STEP 2 (for acquiring specification change data from the mobile terminal 2). Communication).

  Further, the specification change control processing unit 24 determines whether or not the mobile terminal 2 has already acquired the data for changing the specifications by communication with the mobile terminal 2 (whether or not the data for changing the specifications has been downloaded) in STEP3. Check.

  Here, even if the driver of the vehicle 10 (the owner of the mobile terminal 2) is not in the vehicle 10 or is not in the vicinity of the vehicle 10, the mobile terminal 2 is connected via the public communication network 3. By starting the control specification changing application of the portable terminal 2 at an arbitrary location within the area where communication with the server 100 is possible and operating the portable terminal 2, the specification changing data corresponding to the vehicle 10 is stored in the server It is possible to download from 100 to the mobile terminal 2.

  For this reason, in a situation where the determination result of STEP 1 is affirmative, there are a case where the specification change data has already been downloaded to the mobile terminal 2 and a case where the specification change data has not yet been downloaded to the mobile terminal 2. is there.

  If the specification change data has already been downloaded to the mobile terminal 2, the determination result of STEP3 is affirmative, and if the specification change data has not been downloaded to the mobile terminal 2, the determination is made to STEP3. The result is negative.

  In the present embodiment, after the specification change control processing unit 24 completes the process of acquiring the specification change data from the mobile terminal 2, the specification change control processing unit 24 revisits the specification change by communication with the mobile terminal 2. There is a case where a process for acquiring the business data is executed. In this case, the specification change control processing unit 24 recognizes that the determination result in STEP 3 is negative.

  If the determination result in STEP 3 is affirmative, the specification change control processing unit 24 acquires (downloads) specification change data already stored in the mobile terminal 2 from the mobile terminal 2 via the communication device 21. Further, a process of writing the acquired specification change data into a buffer (not shown) provided in the vehicle control device 11 is executed in STEP5.

  The processing of STEP 5 is performed until the determination result of STEP 6 becomes affirmative, that is, until acquisition of specification changing data from the portable terminal 2 is completed (the specification changing data from the portable terminal 2 to the vehicle control device 11 is Executed until the transfer is complete.

  When the determination result of STEP 3 is negative (when the specification change data is not downloaded to the mobile terminal 2 or when the specification change data is reacquired), the specification change control processing unit 24 requests the portable terminal 2 to acquire specification change data from the server 100 in STEP4.

  At this time, the mobile terminal 2 starts communication with the server 100 in response to the request, and acquires specification change data corresponding to the vehicle 10 from the server 100.

  When the portable terminal 2 completes the acquisition of the specification change data from the server 100, the specification change control processing unit 24 executes the process of STEP5 until the determination result of STEP6 becomes affirmative, thereby changing the specification. Data is acquired from the portable terminal 2.

  In the process in which the portable terminal 2 acquires the specification change data through communication with the server 100, the identification data of the vehicle 10 is transmitted from the portable terminal 2 to the server 100. Then, the server 100 transmits specification change data suitable for the vehicle 10 to the mobile terminal 2.

  Supplementally, when the determination result of STEP 3 is negative, the acquisition process of the specification change data from the server 100 by the mobile terminal 2 and the specification change data from the mobile terminal 2 by the specification change control processing unit 24 The acquisition process may be performed in parallel.

  Further, when a plurality of specification change data that can be used in the vehicle 10 are stored in the server 100, the display device 15 of the vehicle 10 or the display device of the mobile terminal 2 ( The contents of a plurality of specification change data that can be provided from the server 100 are displayed on the server 100, and the driver of the vehicle 10 (the owner of the portable terminal 2) operates the screen of the display device 15 or carries it. By operating the terminal 2, desired specification change data (specification change data that the server 100 should transmit from the mobile terminal 2) may be selected.

  When the acquisition of specification change data by the specification change control processing unit 24 is completed and the determination result in STEP 6 becomes affirmative, the specification change control processing unit 24 ends communication with the portable terminal 2 in STEP 7.

  The above processing of STEP 1 to 7 is the processing of the data acquisition unit 24a.

  Next, the specification change control processing unit 24 determines whether or not the specification change data (specification change data written in the buffer) acquired from the portable terminal 2 is normal data in STEP8. This determination process is the process of the data determination unit 24b.

  Here, the specification change data acquired by the mobile terminal 2 from the server 100 may include error data due to poor communication or external noise during communication between the mobile terminal 2 and the server 100.

  Alternatively, the data for specification change acquired from the mobile terminal 2 by the data acquisition unit 24a of the specification change control processing unit 24 is caused by communication failure or external noise at the time of communication between the specification change control processing unit 24 and the mobile terminal 2. Error data may be included.

  Therefore, the specification change control processing unit 24 executes the determination process of STEP8. This determination process can be performed by a known method using an error detection code, an error correction code, or the like.

  When the determination result in STEP 8 is negative (when the specification change data acquired from the mobile terminal 2 includes error data), the specification change control processing unit 24 should acquire the specification change data again. , Processing from STEP2 is resumed. In this case, it is recognized that the determination result in STEP 3 is negative, and the processing from STEP 4 is executed.

  On the other hand, when the determination result in STEP 8 is affirmative (when the specification change data acquired from the mobile terminal 2 is normal data), the specification change control processing unit 24 determines that the acquired specification change is in STEP 9. Data is written to the storage unit 23 which is an empty area among the plurality of change specification storage units 23. Therefore, the specification change data acquired from the portable terminal 2 by the specification change control processing unit 24 is written in the change specification storage unit 23 which is a non-volatile storage unit on the assumption that the determination result of STEP 8 is affirmative. It is.

  In this embodiment, the specification change data stored and held in the change specification storage unit 23 may not be used in the vehicle 10. If the specification change data already written in one change specification storage unit 23 is not in use, the specification change data newly acquired from the storage data of the change specification storage unit 23 You may make it update to.

  When the writing process of STEP 9 is completed, next, the specification change control processing unit 24 determines whether or not the specification change data is normally written to the changed specification storage unit 23 in STEP 10. This determination process can be performed by a known method using an error detection code, an error correction code, or the like, similarly to the determination process of STEP8.

  If the determination result in STEP 10 is affirmative, the specification change control processing unit 24 ends the process of the flowchart of FIG. If the determination result in STEP 10 is negative, the specification change control processing unit 24 re-writes the specification change data into the change specification storage unit 23 by executing the process in STEP 9 again.

  Note that the determination process in STEP 10 can be omitted.

  The process of acquiring the data for changing specifications of the vehicle 10 by the vehicle control device 11 is executed as described above.

  Since the specification change data is acquired by the specification change control processing unit 24 as described above, the driver of the vehicle 10 does not need to operate the mobile terminal 2, and operates the screen of the display device 15 or performs voice input. It is possible to cause the specification change control processing unit 24 to acquire specification change data. For this reason, the driver can cause the specification change control processing unit 24 to acquire specification change data even while the vehicle 10 is in operation.

  Further, the communication between the portable terminal 2 and the server 100 (and the process of acquiring the specification change data from the server 100 by the portable terminal 2) is arranged when the portable terminal 2 is arranged in the vehicle 10. It can be performed in a wide area in any case where it is not (when the driver carrying the portable terminal 2 is away from the vehicle 10 or the like).

  The communication between the portable terminal 2 and the vehicle control device 11 (and the process of acquiring the specification change data by the specification change control processing unit 24 of the vehicle control device 11) is arranged in the vehicle 10 by the portable terminal 2. In the state where it is done, it can carry out irrespective of the location where the vehicle 10 exists.

  For this reason, it is possible to cause the vehicle control device 11 of the vehicle 10 to acquire the specification change data via the portable terminal 2 without being restricted by the location of the vehicle 10.

  Further, the specification change control processing unit 24 of the vehicle control device 11 performs the determination process of STEP8 and further the determination process of STEP10, so that the communication between the mobile terminal 2 and the server 100 or the mobile Even when error data is included in the specification change data during communication between the terminal 2 and the vehicle control device 11, the specification change data including the error data is used as control data for the vehicle 10. It is possible to reliably prevent the change specification storage unit 23 from being stored.

  Next, a process for switching (changing) the control specification of the vehicle 10 from the current control specification to the control specification defined by the specification change data acquired as described above will be described.

  The specification change control processing unit 24 of the vehicle control device 11 executes the processing shown in the flowchart of FIG. 3 after writing the specification change data into the change specification storage unit 23 as described above. This process is the process of the specification switching processing unit 24c. Further, this process is executed regardless of whether or not communication between the mobile terminal 2 and the vehicle control device 11 is possible.

  In STEP 21, the specification change control processing unit 24 determines whether there is a request for switching (changing) the control specification of the vehicle 10.

  In the present embodiment, when switching of the control specification of the vehicle 10 is instructed by a screen operation of the display device 15 or a voice input to the microphone 16, the determination result of STEP 21 is affirmative.

  Specifically, the second operation is displayed on the display device 15 in a state where the mobile terminal 2 can communicate with the vehicle control device 11 or displayed on the display device 15 by a predetermined operation of the display device 15. When the driver of the vehicle 10 touches the unit 15b, the specification switching processing unit 24c of the specification change control processing unit 24 is instructed to switch the control specifications of the vehicle 10.

  Alternatively, when the driver of the vehicle 10 inputs a voice instructing the switching of the control specifications to the microphone 16, the switching of the control specifications is instructed to the specification switching processing unit 24c of the specification change control processing unit 24. The In these cases, the determination result in STEP 21 is positive.

  In this case, since the driver of the vehicle 10 can instruct the switching of the control specifications without requiring the operation of the mobile terminal 2, the instruction can be easily performed even during the driving of the vehicle 10.

  When a plurality of specification change data is stored and held in the change specification storage unit 23, the specification change control processing unit 24 displays the screen of the display device 15 when the control specification change is instructed. The contents of the plurality of specification change data are displayed. Then, the driver of the vehicle 10 selects one specification change data to be newly adopted from the plurality of specification change data by screen operation of the display device 15 or voice input.

  If the determination result in STEP 21 is negative, the specification change control processing unit 24 sequentially repeats the determination process in STEP 21 until the determination result in STEP 21 becomes affirmative. If the determination result in STEP 21 is affirmative, the specification change control processing unit 24 next determines in STEP 22 whether or not the control specification of the vehicle 10 may be switched.

  This determination is made based on a state quantity such as the vehicle speed of the vehicle 10. For example, when the vehicle speed of the vehicle 10 is zero, the determination result of STEP 22 is positive, and when the vehicle speed of the vehicle 10 is not zero, the determination result of STEP 22 is negative.

  Note that, for example, when the power supply voltage of an electronic device (actuator or the like) for controlling the vehicle 10 is taken into consideration, the determination result in STEP 22 is negative even when the power supply voltage is lower than the appropriate lower limit value of the power supply voltage. You may do it.

  Supplementally, the index for determination in STEP 22 may be set in accordance with the content of the control specification to be switched. For example, when the control specification to be switched is the control specification of the air conditioner device of the vehicle 10, the outside air temperature or the like can be used as an index for the determination in STEP22. In this case, the control specification can be switched even while the vehicle 10 is traveling.

  If the determination result in STEP 22 is negative, the specification change control processing unit 24 sequentially repeats the determination process in STEP 22 until the determination result in STEP 22 becomes positive.

  When the determination result in STEP 22 is positive, the specification change control processing unit 24 switches the control specification in STEP 23. Specifically, the specification change control processing unit 24 uses any one of the standard specification storage unit 22 and the change specification storage unit 23 as the data that the vehicle control processing execution unit 25 actually uses as the control data for the vehicle 10. The active storage unit identification data indicating whether the data is stored and held in the storage unit is used as data indicating the changed specification storage unit 23 in which the specification change data instructed by the driver of the vehicle 10 is stored. change.

  Note that the specification change data instructed by the driver is the specification change data when only one of the change specification storage units 23 is written with the specification change data. When the specification change data is written in the change specification storage unit 23, the specification change data is selected by the driver by operating the screen of the display device 15 or by voice input.

  Next, in STEP 24, the specification change control processing unit 24 determines whether or not the specification change data after switching is normal data. This determination process can be performed by a known method using an error detection code, an error correction code, or the like, similarly to the determination process of STEP 8 or STEP 10.

  If the determination result in STEP 24 is affirmative, the specification change control processing unit 24 determines in STEP 25 whether or not the control of the vehicle 10 using the specification change data after switching is normal.

  Here, if the determination result in STEP 24 is affirmative, the specification change data after switching (indicated by the active storage unit identification data) is performed by the vehicle control processing execution unit 25 for at least a predetermined period thereafter. Control of the vehicle 10 is performed using the specification change data stored and held in the changed specification storage unit 23. The determination process in STEP 24 is a process for determining whether or not the control of the vehicle 10 is normal.

  The determination process of STEP 24 is performed based on a value related to the control of the vehicle 10 using the data for changing specifications after switching (for example, a measured value of a predetermined state quantity related to the control).

  Specifically, in a predetermined period after switching of the control specifications, a value related to the control of the vehicle 10 using the data for changing specifications after the switching is set to a predetermined predetermined condition (for example, a predetermined predetermined range). The condition change condition is satisfied for a predetermined time or longer), the specification change control processing unit 24 determines that the control of the vehicle 10 using the specification change data after switching is normal, When the predetermined requirement is not satisfied, it is determined that the control of the vehicle 10 using the data for changing specifications after switching is not normal.

  As an example, when the data for changing the specification after switching changes the target value of the SOC (State of charge) of the power storage device 14 for the purpose of improving the fuel consumption of the vehicle 10, the data for changing the specification after switching When the condition that the fuel consumption of the vehicle 10 realized by the control of the vehicle 10 using the data is equal to or greater than a predetermined value satisfies the necessary condition that it is equal to or longer than the predetermined time, the vehicle 10 using the data for changing specifications after switching. Is determined to be normal.

  Further, when the fuel consumption of the vehicle 10 does not satisfy the necessary condition, it is determined that the control of the vehicle 10 using the specification change data after switching is not normal.

  If the determination result in STEP 25 is affirmative, the control of the vehicle 10 using the data for changing specifications after switching is normal, so the specification change control processing unit 24 ends the process shown in the flowchart of FIG. To do. Thereafter, the control of the vehicle 10 by the vehicle control processing execution unit 25 is performed according to the control specifications defined by the specification change data after the switching until the control specifications are newly changed.

  If the determination process in STEP 25 is negative, the specification change control processing unit 24 switches the control specification of the vehicle 10 to the standard specification in STEP 26. Specifically, the active storage unit identification data is switched to data indicating the standard specification storage unit 22. Then, the specification change control processing unit 24 ends the process shown in the flowchart of FIG.

  Note that the switching of the control specifications in STEP 26 is performed in a situation where the determination result of the same determination process as in STEP 22 is positive.

  When the determination result in STEP 24 is negative (when the data for changing the specification after switching is not normal data), the specification change control processing unit 24 determines that the vehicle in STEP 27 is the same as the processing in STEP 26. 10 control specifications are switched to standard specifications.

  Further, in STEP 28, the specification change control processing unit 24 outputs, to the data acquisition unit 24a, a command to acquire again the specification change data that defines the control specification to be switched in STEP 23.

  In this case, the specification change control processing unit 24 performs the processing from STEP 2 in FIG. 2 in the state where communication between the portable terminal 2 and the vehicle control device 11 is possible, and the data acquisition unit 24a and the data determination unit 24b. To execute. In this case, the determination result in STEP 3 is recognized as negative.

  As a result, the specification change data is newly acquired from the server 100 via the portable terminal 2 and written into the changed specification storage unit 23.

  The above is the details of the processing related to switching of the control specifications.

  According to the first embodiment described above, the vehicle control device 11 can acquire specification change data from the server 100 via the mobile terminal 2. For this reason, the control specification changing system 1 that is convenient or easy to use can be realized at low cost.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIGS. Note that the description of the present embodiment is centered on matters that are different from the first embodiment, and descriptions of the same matters as the first embodiment are omitted.

  With reference to FIG. 4, in this embodiment, in addition to the structure demonstrated in 1st Embodiment, the vehicle control apparatus 11 acquires the vehicle information data which show the information regarding the vehicle 10, and the acquired vehicle information data Is further provided with the vehicle information data transmission part 31 which transmits to the server 100 via the portable terminal 2. FIG.

  In this embodiment, the vehicle information data includes detection data or estimation data of a plurality of types of state quantities related to the vehicle 10.

  More specifically, the vehicle 10 includes, for example, a GPS receiver 32 that receives GPS information including position information and date / time information of the vehicle 10, and a temperature sensor 33 that detects an ambient temperature (outside temperature) around the vehicle 10. The gyro sensor 34 for detecting the spatial posture of the vehicle 10 (for example, the tilt angle in the pitch direction and the roll direction), the vehicle speed sensor 35 for detecting the vehicle speed of the vehicle 10, and the operation of the accelerator pedal of the vehicle 10 An accelerator sensor 36 for detecting the amount (hereinafter referred to as the accelerator operation amount) and an SOC estimation sensor 37 for estimating the state of charge SOC of the power storage device 14 (the output voltage and energization current of the power storage device 14 are detected, respectively. Voltage sensor and current sensor).

  And the vehicle information data transmission part 31 is based on the output of each said detector in the state in which the portable terminal 2 is arrange | positioned at the vehicle 10, and this portable terminal 2 and the vehicle control apparatus 11 can communicate. Recognized detection data or estimated data is acquired as vehicle information data.

  Specifically, the vehicle information data transmission unit 31 detects the GPS information (position information and date / time information of the vehicle 10) received by the GPS receiver 32, the outside air temperature detected by the temperature sensor 33, and the gyro sensor 34. The attitude of the vehicle 10, the vehicle speed detected by the vehicle speed sensor 35, the accelerator operation amount detected by the accelerator sensor 36, the SOC of the power storage device 14 estimated from the output of the SOC estimation sensor 37, and the fuel consumption estimation of the vehicle 10 A quantity (e.g., a value estimated from an instruction value of a fuel meter (not shown) of the fuel tank for the engine 13 and an instruction value of an odometer of the vehicle 10), and a period of a predetermined time (currently) The transition from the time to a predetermined time before) is acquired as vehicle information data.

  Further, the vehicle information data transmission unit 31 transmits the acquired vehicle information data from the communication device 21 of the vehicle control device 11 to the portable terminal 2. At this time, the portable terminal 2 communicates with the server 100 according to a command from the vehicle information data transmission unit 31 and transfers the vehicle information data transmitted from the vehicle control device 11 to the server 100.

  Thus, in this embodiment, the vehicle information data of the vehicle 10 is transmitted to the server 100 via the portable terminal 2 in a state where the portable terminal 2 and the vehicle control device 11 can communicate with each other. In this case, identification data of the vehicle 10 and data indicating a control specification used in the vehicle 10 when the vehicle information data is transmitted (hereinafter referred to as transmission use control specification data) are transmitted to the server 100 together with the vehicle information data. The

  Then, the server 100 stores the vehicle information data and the transmission use control specification data transmitted from the vehicle 10 in association with the identification data of the vehicle 10. The transmission of vehicle information data and the like to the server 100 is performed in the same manner for other vehicles equipped with a system similar to the control specification change system 1 of the present embodiment.

  Further, the server 100 performs an error check (judgment processing similar to STEP 8) on whether or not the data such as the vehicle information data transmitted from the vehicle 10 is normal data, and there is an error in the received data The mobile terminal 2 is requested to transmit the vehicle information data again. The same applies to data transmitted from another vehicle to the server 100.

  In the present embodiment, the server 100 uses the vehicle information data to specify a control specification suitable for the vehicle 10 when transmission of specification change data is requested by communication with the mobile terminal 2 corresponding to the vehicle 10. The specification change data corresponding to the determined control specification is transmitted to the portable terminal 2.

  Hereinafter, the processing of the server 100 will be described with reference to FIGS. In the following description, the vehicle 10 whose control specification is to be changed is referred to as a target vehicle 10. Further, unless otherwise specified, the other vehicle means another vehicle that transmits vehicle information data to the server 100 as appropriate, such as another vehicle equipped with a system similar to the control specification changing system 1 of the present embodiment. To do.

  The server 100 executes the process shown in the flowchart of FIG. 5 when the transmission of the specification change data is requested by communication with the mobile terminal 2 corresponding to the vehicle 10.

  First, in STEP 31, the server 100 classifies the status of the target vehicle 10 (the status of the usage environment for the target vehicle 10) from the vehicle information data (latest vehicle information data) received from the mobile terminal 2 corresponding to the target vehicle 10. .

  The processing of STEP 31 is executed as shown in the flowchart of FIG. 6 as an example. In the present embodiment, the situation of the target vehicle 10 is classified into one of six situations: a high outside air temperature situation, a low outside air temperature situation, a high gradient situation, a traffic jam situation, a suburban situation, and a standard situation.

  Specifically, when it is determined in STEP 41 that the target vehicle 10 is used in a high outside air temperature region (when the determination result in STEP 41 is affirmative), the server 100 determines in STEP 42 that the target vehicle 10 The situation of 10 is determined to be a high outside air temperature situation in which the target vehicle 10 is in a high outside air temperature region.

  The determination of STEP 41 is made based on the outside air temperature in the vehicle information data, and when the outside air temperature is higher than a predetermined high outside air temperature determination temperature, the determination result of STEP 41 is affirmative.

  Further, when it is determined in STEP 43 that the target vehicle 10 is used in a low outside air temperature region (when the determination result in STEP 43 is affirmative), the server 100 determines the status of the target vehicle 10 in STEP 44. However, it is determined that the target vehicle 10 is in a low outside air temperature situation in the low outside air temperature region.

  The determination in STEP 43 is made based on the outside air temperature in the vehicle information data, and when the outside air temperature is lower than a predetermined low outside air temperature determination temperature, the determination result in STEP 43 is affirmative.

  Further, when it is determined in STEP 45 that the target vehicle 10 is used in a high-gradient area (when the determination result in STEP 45 is affirmative), the server 100 determines that the status of the target vehicle 10 is in STEP 46. It is determined that the target vehicle 10 is in a high gradient state in a high gradient area.

  The determination in STEP 45 is made based on the posture of the target vehicle 10 in the vehicle information data (specifically, the inclination angle in the pitch direction), and the absolute value of the inclination angle in the pitch direction is based on a predetermined high gradient determination angle. A large value is a case where the determination result in STEP 45 is positive.

  Further, when it is determined in STEP 47 that the target vehicle 10 is being used in a traffic jam area (when the determination result in STEP 47 is affirmative), the server 100 determines in step 48 that the status of the target vehicle 10 is It is determined that the target vehicle 10 is in a traffic jam situation in a traffic jam area.

  The determination in STEP 47 is made based on, for example, a change in vehicle speed and a change in accelerator operation amount in the vehicle information data. For example, when it is estimated from the transition of the vehicle speed and the transition of the accelerator operation amount that the target vehicle 10 alternately repeats stopping and starting due to traffic jam, the determination result of STEP 47 is positive.

  More specifically, for example, when the vehicle speed is lower than a predetermined value and the vehicle speed is zero (the vehicle is stopped) in a predetermined short time, or If the state where the accelerator operation amount is zero and the state where the accelerator operation amount is not zero are repeated within a predetermined short time, the determination result of STEP 47 is affirmative.

  In addition, when it is determined in STEP 49 that the target vehicle 10 is used in a suburban area (when the determination result in STEP 49 is affirmative), the server 100 determines in step 50 that the status of the target vehicle 10 is It is determined that the target vehicle 10 is in a suburban situation in a suburban area.

  The determination in STEP 49 is made based on the change in vehicle speed and the change in accelerator operation amount in the vehicle information data. For example, when the vehicle speed is kept constant (or almost constant) for a predetermined value or more, or the accelerator operation amount is kept constant (or almost constant) for a predetermined value or more In addition, the determination result in STEP 49 is positive.

  Note that the determination conditions of STEP 41, 43, 45, 47, and 49 are set based on experiments in advance so that the situation of any vehicle including the target vehicle 10 can be appropriately classified.

  Furthermore, the server 100 does not correspond to any of the above five situations (high outside air temperature situation, low outside air temperature situation, high gradient situation, traffic jam situation and suburban situation) (STEP 41, 43, When all the determination results of 45, 47, and 49 are negative), in STEP 51, it is determined that the situation of the target vehicle 10 is the standard situation.

  The conditions for classifying the situation of the target vehicle 10 are not limited to the above. For example, the situation of the target vehicle 10 may be classified based on position information and date / time information received by the GPS receiver 32 and other information.

  For example, when the other information is the predicted temperature based on the weather forecast, the predicted temperature of the weather forecast for the position information and date / time information of the target vehicle 10 can be used as the estimated value of the actual outside temperature. In addition, when the other information is statistical information on the past outside air temperature of each region, the outside air temperature estimated from the outside air temperature in the statistical information corresponding to the position information and date / time information of the target vehicle 10 is obtained. It can also be used as an estimated value of the actual outside air temperature.

  Then, the server 100 determines whether or not the situation of the target vehicle 10 is a high outside air temperature situation where the target vehicle 10 is in a high outside air temperature region based on the estimated value of the outside air temperature obtained as described above. It may be made to judge whether the situation of vehicles 10 is the low outside temperature situation where object vehicles 10 are in a low outside temperature area.

  Further, for example, when the other information is the road surface gradient set in the map data or the like that can be referred to by the server 100, the road surface set in the map data or the like corresponding to the position information of the target vehicle 10 Can be used as an estimated value of the inclination angle of the target vehicle 10 in the actual pitch direction. In this case, based on the estimated value of the tilt angle, it can be determined whether or not the situation of the target vehicle 10 is a high gradient situation where the target vehicle 10 is in a high gradient area.

  For example, when the other information is traffic jam information, it can be determined whether the status of the target vehicle 10 is a traffic jam status based on the traffic jam information corresponding to the position information of the target vehicle 10. .

  Further, for example, when the other information is map data or the like that can be referred to by the server 100, whether or not the situation of the target vehicle 10 is a suburban situation based on traffic jam information corresponding to the position information of the target vehicle 10 is determined. Can be judged.

  The classification of the situation of the target vehicle 10 is not limited to the six situations shown in FIG. 6, but other situations (for example, situations where the vehicle is traveling on a highway) may be adopted. Alternatively, the situation of the target vehicle 10 may be classified by being limited to some of the six situations shown in FIG.

  The details of the processing of STEP 31 have been described above.

  Returning to the description of FIG. 5, when the processing of STEP 31 is completed (the processing of the flowchart of FIG. 6 is completed), the server 100 then receives the vehicle information data received in the past (received in the past) in STEP 32. Among the stored vehicle information data), vehicle information data in the same situation as the situation of the target vehicle 10 is acquired.

  Specifically, the server 100 first classifies the status of the other vehicle at the time of receiving the vehicle information data by performing the same processing as in the flowchart of FIG. 6 for each vehicle information data received for the other vehicle. Then, the server 100 includes one or a plurality of vehicle information data (hereinafter referred to as such vehicle information data) classified in the same situation as the situation of the target vehicle 10 classified in STEP 31 among the received vehicle information data. The same situation vehicle information data).

  The same situation vehicle information data has a predetermined relationship with the vehicle information data (latest vehicle information data) received for the target vehicle 10 (in this embodiment, a relationship that the same situation as the target vehicle 10 is present). This corresponds to vehicle information data of the vehicle.

  Next, in STEP 33, the server 100 determines a control specification (a new control specification different from the control specification that the target vehicle 10 is currently using) that matches the status of the target vehicle 10 based on the same situation vehicle information data. Details of this processing will be described later.

  Next, in STEP 34, the server 100 determines specification change data corresponding to the control specification determined as described above, and further transmits the specification change data to the mobile terminal 2. As a result, specification change data defining a control specification suitable for the target vehicle 10 is transmitted from the server 100 to the mobile terminal 2.

  Details of the processing of STEP 33 will be described below.

  In the processing of STEP 33, for example, the server 100 has the same fuel consumption (for example, average fuel consumption within a certain period of time) recognized from the estimated fuel consumption amount and its transition in each identical situation vehicle information data higher than the fuel consumption of the target vehicle 10. The control specification of the target vehicle 10 is determined based on the transmission use control specification data representing the control specification of the other vehicle that has transmitted the situation vehicle information data (the control specification at the time of transmission of the same situation vehicle information data).

  Specifically, the server 100 sets the control specification indicated by the transmission use control specification data of the other vehicle that has transmitted the same-situation vehicle information data having the highest fuel efficiency than the target vehicle 10 among the same-situation vehicle information data. A new control specification that matches the situation of the target vehicle 10 is determined.

  Here, the control specifications of the motor 12 and the engine 13 by the vehicle control device 11 of the target vehicle 10 are, for example, the target SOC of the power storage device 14 or the target output of the motor 12 according to the accelerator operation amount and the vehicle speed of the target vehicle 10. A control specification for controlling the operation of the electric motor 12 and the engine 13 using a map for determining torque (hereinafter referred to as a motor torque map) or the like may be used.

  In this case, by changing the target SOC or motor torque map used in the vehicle control device 11 of the target vehicle 10 or by determining a new control specification of the target vehicle 10 so as to change the starting condition of the engine 13. In each situation of the target vehicle 10 classified as described above (the situation of the usage environment of the target vehicle 10), a new control specification can be determined so as to improve the fuel consumption of the target vehicle 10.

  Thus, the server 100 determines the control specification of the target vehicle 10 based on the vehicle information data of one or more other vehicles in the same situation as the situation of the target vehicle 10. For this reason, compared with the case where the control specification of the target vehicle 10 is determined based on only the vehicle information data of the target vehicle 10, more situations are taken into consideration, so that the control specification more suitable for the situation of the target vehicle 10 Can be determined.

  In addition, since the server 100 determines the control specification of the target vehicle 10 using the vehicle information data received from the other vehicle, the target vehicle 10 The control specification suitable for the situation can be determined.

  Note that the server 100 determines a control specification that improves fuel efficiency as a new control specification that matches the situation of the target vehicle 10, for example, instead of improving the fuel efficiency, or in addition to improving the fuel efficiency, A new control specification may be determined so that durability (life) of the power storage device 14 of the vehicle 10 or drivability of the target vehicle 10 is improved.

  The present embodiment is the same as the first embodiment except for the matters described above.

  According to the present embodiment, the server 100 generates a control specification (and thus specification change data) that matches the target vehicle 10 based on the vehicle information data of the target vehicle 10 and the same-state vehicle information data of other vehicles. decide. For this reason, the vehicle control device 11 of the target vehicle 10 does not require a selection process of the driver of the target vehicle 10 and the like, and changes specification data suitable for the target vehicle 10 from the server 100 via the portable terminal 2. Can be acquired.

  For this reason, the convenience or usability of the control specification changing system 1 of the present embodiment can be further enhanced.

[Modification]
Next, some modifications related to the above-described embodiment will be described.

  In each of the above embodiments, the hybrid vehicle has been described as an example of a vehicle whose control specifications can be changed. However, a vehicle whose control specifications can be changed is a vehicle having only one of the engine 13 and the electric motor 12 as a power source. There may be. Further, the vehicle whose control specifications can be changed may be a motorcycle, a working vehicle, or the like.

  In each of the above embodiments, a system including the microphone 16 as a voice input unit has been described. However, the voice input unit may be omitted.

  Further, in each of the above embodiments, the screen of the display device 15 includes the first operation unit 15a that instructs the vehicle control device 11 to acquire specification change data or the second operation unit 15b that instructs switching of the control specifications. However, these operation units 15a and 15b are machine operation type operation units provided around the display device 15 of the vehicle 10 or a steering handle of the vehicle 10 or the like. There may be.

  Moreover, in the said 2nd Embodiment, in order to determine the control specification of the target vehicle 10 with the server 100, the vehicle information data of the other vehicle was used, For example, based on only the vehicle information data of the target vehicle 10, the target The control specifications of the vehicle 10 may be determined.

  As an example, a new control specification of the target vehicle 10 according to the six situations related to the target vehicle 10 (a high outside temperature state, a low outside temperature state, a high gradient state, a traffic jam state, a suburban state, and a standard state) is stored in the server 100. A specific example in the case of determining by will be schematically described below.

  In this example, when the situation of the target vehicle 10 is a standard situation, the server 100 changes the target SOC or the motor torque map so as to improve fuel consumption (or improve the durability of the power storage device 14). Thus, a new control specification of the target vehicle 10 is determined.

  Moreover, when the situation of the target vehicle 10 is a high outside air temperature situation, it is predicted that the air conditioner device of the target vehicle 10 is frequently used. For this reason, the server 100 changes to a motor torque map that considers the use of the air conditioner, or conditions for starting the engine 13 while the target vehicle 10 is traveling only by the driving force of the electric motor 12 (hereinafter referred to as the engine during EV traveling). A new control specification of the target vehicle 10 is determined so as to change the starting condition).

  Further, when the situation of the target vehicle 10 is a low outside air temperature situation, the output efficiency of the power storage device 14 is reduced. For this reason, the server 100 determines a new control specification of the target vehicle 10 so as to change to a motor torque map that takes into account a decrease in output efficiency of the power storage device 14.

  Further, when the state of the target vehicle 10 is a high gradient state, it can be expected that a large amount of electric power generated by the regenerative operation of the electric motor 12 is obtained while the target vehicle 10 is traveling downhill. For this reason, the server 100 changes the new control specification of the target vehicle 10 so as to change the target SOC to a value smaller than normal.

  Moreover, when the situation of the target vehicle 10 is a traffic jam situation, it is predicted that the stop and start of the target vehicle 10 are repeated in a short time. For this reason, the server 100 changes the control specifications so as to use the motor torque map and the target SOC considering this.

  Moreover, when the situation of the target vehicle 10 is a suburban situation, it is predicted that the frequency of stopping and starting the target vehicle 10 will be low. For this reason, the server 100 changes the control specification so as to use the motor torque map and the target SOC in consideration of this.
