(First embodiment)
FIG. 1 is a diagram showing an outline of a system configuration of a vehicle air conditioner according to first and second embodiments of the present invention.

The air conditioner system 3 includes a heating device such as a so-called PTC heater that uses electrical energy, a combustion heater that uses heat obtained by burning fuel, and a vehicle interior that is controlled in an integrated manner with the air conditioner described above. And a blower device for blowing air. The air conditioner system 3 automatically switches the operation method such as the operation of the blower device, the air conditioner and the heating device, the operation of the blower device and the air conditioner, the operation of the blower device and the heating device, and the operation of only the blower device for suppressing power consumption. Optimum air conditioning of the passenger compartment according to the condition of the vehicle.

  The air conditioner system 3 may be configured such that the driving method (mode) can be changed by a user's selection. For example, a selection menu of “normal mode, rapid mode, energy saving mode, etc.” is displayed on the screen of the user's mobile terminal. Furthermore, by changing the mode of the air conditioner system 3 based on the mode selected by the user, the temperature in the passenger compartment is adjusted by a method that best suits the user's needs.

  Here, the rapid mode is a mode for causing the temperature in the passenger compartment to reach the target temperature in a short time (a mode in which power consumption is increased), and the energy saving mode is to minimize the power consumption of the air conditioner system 3. It is a mode for. The normal mode is a mode adjusted between the rapid mode and the energy saving mode.

  The air conditioner system 3 is connected to power storage means 5 such as a battery for supplying electric power for driving the air conditioner system 3. The battery 5 may be charged by an external power supply connected to the battery 5 and stored by electricity supplied from the external power supply, or may be stored by electricity generated while the vehicle is running by an on-vehicle generator.

  A storage amount detection sensor 7 such as a voltmeter for detecting the storage amount of the battery 5 is attached to the battery 5, and the storage amount detection sensor 7 is connected to an ECU 9 described later.

  A control means 9 such as an ECU for controlling the air conditioner system 3 is connected to the air conditioner system 3. The air conditioner system 3 cools or heats the passenger compartment based on a control signal from the ECU 9 and adjusts the temperature of the passenger compartment.

  The ECU (Electronic Control Unit) 9 is composed of a microcomputer, and executes various processes in accordance with control and arithmetic programs, and stores a CPU (Central Processing Unit) for controlling each part of the apparatus, and a CPU execution program. A ROM (Read Only Memory), a readable / writable RAM (Random Access Memory) for storing calculation results, a timer, a counter, an input interface, and an output interface.

  The ECU 9 is connected to an indoor temperature sensor 11 that detects the temperature in the vehicle interior and an outside air temperature sensor 13 that detects the temperature of the outside air. The ECU 9 controls the air conditioner system 3 so as to reach the target set temperature based on the temperature in the vehicle compartment detected from the indoor temperature sensor 11 and the temperature of the outside air detected from the outside air temperature sensor 13.

  The ECU 9 has target temperature setting means 9a for setting a target temperature when the air conditioner system 3 performs air conditioning. The target temperature setting means 9a may set the target temperature based on, for example, a signal from a switch or the like installed in the passenger compartment, from a mobile terminal such as a mobile phone, a PDA (Personal Data Assistants), or a remote control key. The target temperature may be set based on the signal. Further, the target temperature setting means 9a may automatically set a preset optimum temperature based on the temperature of the outside air detected from the outside air temperature sensor 13. The target temperature setting means 9a is configured to change the target temperature once set based on a signal from a portable terminal or the like.

  When the target temperature is set, for example, a specific temperature (such as 20 ° C.) may be input from the user's portable terminal, and this numerical value may be set as the target temperature by the target temperature setting means 9a. In addition, a menu of “comfortable, slightly cool, normal, warm, etc.” is displayed on the screen of the mobile terminal, and when the user selects this menu, the target temperature corresponding to this selection is simplified by the target temperature setting means 9a. And it may be set automatically.

  The ECU 9 has an adjustability determination unit 9b that determines whether or not the temperature in the passenger compartment can be adjusted to the target temperature set by the target temperature setting unit 9a. The adjustability determination unit 9b includes a storage amount detected by the storage amount detection sensor 7, a temperature in the vehicle interior detected by the room temperature sensor 11, a temperature of the outside air detected by the outside temperature sensor 13, and a target temperature setting. Based on the target temperature set by the means 9a and the characteristics of the air conditioner system 3, it is determined whether or not the air conditioner system 3 can adjust the temperature in the vehicle interior to the target temperature.

  For example, the adjustability determination unit 9b detects when the voltage of the battery 5 detected by the charged amount detection sensor 7 is low (below a predetermined voltage) and the difference between the current temperature in the vehicle compartment and the target temperature is large (predetermined temperature). At the time described above, it is determined that the amount of power stored in the battery 5 is insufficient, the necessary electric power cannot be supplied to the air conditioner system 3, and the temperature in the passenger compartment cannot be cooled or warmed up to the target temperature.

  The ECU 9 has time predicting means 9c for predicting the arrival time until the temperature in the vehicle interior reaches the target temperature. In addition, when the time predicting unit 9c determines that the temperature of the passenger compartment cannot be adjusted to the target temperature by the adjustability determining unit 9b, the time predicting unit 9c is used when reaching the temperature closest to the target temperature (hereinafter referred to as a temporary target temperature). Predict arrival time. Furthermore, after the temperature in the passenger compartment reaches the target temperature, the time predicting unit 9c predicts a holding time (X minutes, X hours, etc.) that can hold the target temperature.

  The time predicting unit 9c determines that the temperature in the vehicle interior is the target temperature based on the temperature in the vehicle interior detected by the indoor temperature sensor 11, the temperature of the outside air detected by the outside air temperature sensor 13, and the characteristics of the air conditioner system 3.

  Furthermore, the time predicting unit 9c can predict the arrival time, holding time, and predicted temperature change curve for reaching the target temperature or temporary target temperature for each mode (normal mode, rapid mode, energy saving mode) of the air conditioner system 3 described above. Good.

  The time predicting unit 9c may predict a change in the outside air temperature based on weather information, calendar information, and the like acquired from the information providing unit via the transceiver 15. The time prediction unit 9c predicts the arrival time, the holding time, and the predicted temperature change curve that reach the target temperature or the temporary target temperature described above in consideration of the change in the outside air temperature, thereby improving the accuracy of the prediction.

  The target temperature setting means 9a, the adjustment availability determination means 9b, the time prediction means 9c, and the scheduled time setting means 9d described later are stored in the ROM and realized as execution programs executed by the CPU.

  The ECU 9 is connected to a transceiver 15 that transmits and receives signals and data to and from an external communication device such as a portable terminal. The ECU 9 receives signals and data from a portable terminal or the like via the transceiver 15 and transmits signals and data to the portable terminal or the like via the transceiver 15.

  The arrival time, the holding time, and the predicted temperature change curve at which the vehicle interior temperature predicted by the time prediction means 9c reaches the target temperature or the temporary target temperature are transmitted to the user's portable terminal via the transceiver 15, It is displayed on the screen of the mobile terminal.

  The arrival time (or arrival time) predicted by the time predicting unit 9c is displayed on the screen of the portable terminal, for example, “Set temperature after X minutes from now”, “Set temperature when X”, etc. You may let them. Moreover, you may display the estimated temperature change curve for every mode of the air-conditioning system 3 mentioned above with the arrival time estimated by the time estimation means 9c on the screen of a portable terminal (FIG. 2). Thereby, it becomes a standard when a user gets on, and the convenience improves.

  Further, a mode selection menu such as the normal mode, the rapid mode, and the energy saving mode described above may be displayed by superimposing on the predicted temperature change curve for each mode of the air conditioner system 3 (FIG. 2). In addition, if the predicted temperature change curve is displayed with temperature (° C.) on the vertical axis and time (minutes, seconds, etc.) on the horizontal axis, the recognizability by the user is improved. In this way, the user can easily and reliably select the optimum air conditioner system 3 mode.

  When the ECU 9 receives the ON signal from the portable terminal via the transceiver 15, the ECU 9 activates the air conditioner system 3. On the other hand, when the ECU 9 receives an off signal from the portable terminal via the transceiver 15, the ECU 9 stops the air conditioner system 3. As described above, the vehicle air conditioner 1 according to the present embodiment is configured so that general operations of the air conditioner system 3 such as power on / off, target temperature setting, and the like can be remotely performed by a portable terminal. Yes.

  Next, the control process of the vehicle air conditioner 1 configured as described above will be described in detail.

  FIG. 3 is a flowchart showing a control processing flow of the vehicle air conditioner 1 according to the first embodiment.

  As shown in FIG. 3, an on signal of the air conditioner system 3 is transmitted from the portable terminal to the ECU 9, and the ECU 9 receives the on signal via the transceiver 15 (S100).

  Next, the target temperature in the passenger compartment is transmitted from the portable terminal to the ECU 9, and is received by the target temperature setting means 9a of the ECU 9 via the transceiver 15, and the target temperature is set (S110). Note that the ON signal and the target temperature of the air conditioner system 3 may be simultaneously transmitted to the ECU 9 by the portable terminal.

  After that, the adjustability determining means 9b is configured to detect the amount of electricity stored by the amount of electricity detection sensor 7, the temperature in the vehicle interior detected by the indoor temperature sensor 11, the temperature of the outside air detected by the outside air temperature sensor 13, the target Based on the target temperature set by the temperature setting means 9a and the characteristics of the air conditioner system 3, it is determined whether or not the temperature of the passenger compartment can be adjusted to the target temperature by the air conditioner system 3 (S120).

  The ECU 9 transmits a drive signal to the air conditioner system 3 when it is determined by the adjustability determination unit 9b that the temperature in the vehicle compartment can be adjusted to the target temperature. The air conditioner system 3 that has received the drive signal starts temperature adjustment so that the temperature in the passenger compartment becomes the target temperature (S130). At this time, the user may select a mode of the air conditioner system 3 using the portable terminal, and the air conditioner system 3 may be configured to adjust the temperature based on the user's mode selection.

  Next, the time predicting unit 9c sets the target temperature based on the temperature in the vehicle interior detected by the indoor temperature sensor 11, the temperature of the outside air detected by the outside air temperature sensor 13, and the characteristics of the air conditioner system 3 described above. The arrival time, the retention time, and the predicted temperature change curve to be reached are predicted (S140).

  Thereafter, the ECU 9 transmits the arrival time, the holding time, and the predicted temperature change curve predicted by the time prediction unit 9c to the user's portable terminal via the transceiver 15 (S150).

  The mobile terminal that has received the data from the ECU 9 displays the arrival time for reaching the target temperature, the holding time, and the predicted temperature change curve on the screen.

  Since the user can recognize the temperature change in the passenger compartment from the displayed predicted temperature change curve, the user can intentionally shift the time and board at a temperature different from the target temperature at the time of setting. Become. In this way, the user can easily change the temperature environment at the time of boarding, and convenience is improved.

  On the other hand, the ECU 9 transmits a drive signal to the air conditioner system 3 when it is determined by the adjustability determination unit 9b that the temperature in the passenger compartment cannot be adjusted to the target temperature. The air conditioner system 3 that has received the drive signal starts adjustment so that the temperature in the passenger compartment becomes the temporary target temperature (S160).

  Next, the time predicting unit 9c uses the temperature inside the vehicle detected by the indoor temperature sensor 11, the temperature of the outside air detected by the outside air temperature sensor 13, the characteristics of the air conditioner system 3 described above, and the storage amount detection sensor 7. Based on the detected power storage amount, an arrival time and predicted temperature change curve for reaching the temporary target temperature are predicted (S170).

  Thereafter, the ECU 9 transmits, via the transmitter / receiver 15, the arrival time and the expected temperature change curve for reaching the temporary target temperature predicted by the time prediction unit 9c to the user's portable terminal (S180).

  The mobile terminal that has received the data from the ECU 9 displays the arrival time for reaching the temporary target temperature and the predicted temperature change curve on the screen. At this time, for example, a display for confirming the user's intention may be displayed on the screen of the mobile terminal, such as “Is it best to approach the temperature most suitable after X minutes?”. Thereby, a user operation mistake etc. can be reduced.

  As described above, when the adjustment availability determination unit 9b determines that the temperature in the vehicle compartment cannot be adjusted to the target temperature due to the shortage of the storage amount of the battery 5, the user's portable terminal is notified that the adjustment is not possible. Thereby, since the user can recognize in advance that the temperature in the passenger compartment cannot be adjusted to the target temperature, the convenience for the user is improved.

When it is determined by the adjustability determining means 9b that the temperature in the vehicle interior cannot be adjusted to the target temperature, the time predicting means 9c predicts the arrival time and the predicted temperature change curve that reach the temporary target temperature, and the user's portable terminal Notify Thereby, the user can recognize the arrival time to reach the temporary target temperature that is the temperature closest to the target temperature as the best alternative when the temperature in the vehicle interior cannot be adjusted to the target temperature. Therefore, if the user gets on the vehicle in accordance with the arrival time of the temporary target temperature, the best temperature environment is provided to the user in a vehicle situation such as a shortage of the charged amount of the battery 5. That is, user convenience is improved.
(Second Embodiment)
The vehicle air conditioner 1 according to the second embodiment includes a scheduled time setting unit 9d that sets a scheduled time for the user to get on.

  The user's scheduled boarding time is input to the user's portable terminal and transmitted to the ECU 9 via the transceiver 15. The scheduled time setting means 9d sets the scheduled boarding time for the user based on the data transmitted from the portable terminal.

  The time predicting unit 9c also includes a vehicle interior temperature detected by the indoor temperature sensor 11, an outside air temperature detected by the outside air temperature sensor 13, a target temperature set by the target temperature setting unit 9a, and a scheduled time. The driving start time of the air conditioner system 3 is calculated based on the scheduled boarding time of the user set by the setting means 9d and the characteristics of the air conditioner system 3.

  The drive start time of the air conditioner system 3 is the time when the air conditioner system 3 starts to be driven so that the temperature in the passenger compartment becomes the target temperature at the scheduled boarding time of the user.

  The adjustability determination unit 9b includes a storage amount detected by the storage amount detection sensor 7, a temperature in the vehicle interior detected by the indoor temperature sensor, a temperature of the outside air detected by the outside temperature sensor 13, and a target temperature setting unit. Based on the target temperature set by 9a, the scheduled boarding time set by the scheduled time setting means 9d, and the characteristics of the air conditioner system 3, the temperature in the passenger compartment is set to the target temperature by the air conditioning system 3 by the scheduled boarding time. It is determined whether or not adjustment is possible.

  For example, the adjustment availability determination unit 9b has a low voltage of the battery 5 detected by the charged amount detection sensor 7 (below a predetermined voltage) and a large difference between the current temperature in the vehicle compartment and the target temperature (above the predetermined temperature). And when there is no time until the scheduled boarding time (within a predetermined time), it is determined that the temperature in the passenger compartment cannot be cooled or warmed up to the target temperature by the scheduled boarding time of the user.

  The determination by the adjustment availability determination unit 9b is transmitted to the user's portable terminal via the transceiver 15 together with the driving start time of the air conditioner system 3 calculated by the time prediction unit 9c.

  Other configurations are substantially the same as the configuration of the vehicle air conditioner according to the first embodiment. The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  Next, the flow of control processing of the vehicle air conditioner 1 according to the second embodiment configured as described above will be described.

  FIG. 4 is a flowchart showing a control processing flow of the vehicle air conditioner 1 according to the second embodiment.

  As shown in FIG. 4, an ON signal of the air conditioner system 3 is transmitted from the portable terminal to the ECU 9, and the ECU 9 receives this ON signal via the transceiver 15 (S200).

  Next, the target temperature in the passenger compartment is transmitted from the portable terminal to the ECU 9 and received by the target temperature setting means 9a of the ECU 9 via the transceiver 15, and the target temperature is set.

  At the same time, the scheduled boarding time of the user is transmitted from the portable terminal to the ECU 9, and is received by the scheduled time setting means 9d of the ECU 9 via the transceiver 15, and the scheduled time is set (S210).

  After that, the adjustability determining means 9b is configured to detect the amount of electricity stored by the amount of electricity detection sensor 7, the temperature in the vehicle interior detected by the indoor temperature sensor 11, the temperature of the outside air detected by the outside air temperature sensor 13, the target Based on the target temperature set by the temperature setting means 9a, the scheduled boarding time set by the scheduled time setting means 9d, and the characteristics of the air conditioner system 3, the temperature of the vehicle interior is set by the air conditioner system 3 by the scheduled boarding time. It is determined whether or not the target temperature can be adjusted (S220).

  When it is determined by the adjustability determining means 9b that the temperature in the vehicle interior can be adjusted to the target temperature, the time predicting means 9c is detected by the temperature in the vehicle interior detected by the indoor temperature sensor 11 and the outside air temperature sensor 13. The air conditioner system 3 is driven based on the outside air temperature, the target temperature set by the target temperature setting means 9a, the scheduled boarding time of the user set by the scheduled time setting means 9d, and the characteristics of the air conditioner system 3. A start time is calculated (S230).

  Next, the ECU 9 transmits, to the user's portable terminal, the fact that the temperature in the passenger compartment can be adjusted to the target temperature and the driving start time of the air conditioner system 3 calculated by the time predicting means 9c via the transceiver 15 (S240). ).

  On the other hand, when it is determined by the adjustability determination unit 9b that, for example, the temperature inside the vehicle compartment cannot be adjusted to the target temperature because the amount of power stored in the battery 5 is small, the time predicting unit 9c The drive start time of the air conditioner system 3 is tentatively calculated such that the predetermined amount of power is left and the temperature in the passenger compartment is closest to the target temperature (S250). If the air conditioner system 3 is driven in accordance with the drive start time, an optimal temperature environment in the passenger compartment can be realized even when the amount of power stored in the battery 5 is small.

  For example, in the case of the battery 5 made of lead, the predetermined power storage amount is a power storage amount obtained by adding a power storage amount that does not cause performance deterioration of the battery 5 to a power storage amount required for starting the engine. Further, in the case of the battery 5 made of nickel, lithium or the like, the charged amount required for starting the engine becomes a predetermined charged amount.

  Next, the ECU 9 transmits, to the user's portable terminal, the fact that the temperature in the passenger compartment cannot be adjusted to the target temperature and the driving start time of the air conditioner system 3 calculated by the time prediction means 9c via the transceiver 15 (S260). ).

  Note that the ECU 9 transmits a drive signal to the air conditioner system 3 when the drive start time or provisional drive start time is reached. The air conditioner system 3 that has received the drive signal starts adjusting the temperature in the passenger compartment.

  As described above, when the adjustment possibility determination unit 9b determines that the temperature in the vehicle interior can be adjusted to the target temperature, the time prediction unit 9c calculates the drive start time of the air conditioner system 3, and the air conditioner system 3 detects the drive start time. Based on the above, temperature adjustment in the passenger compartment is started. Accordingly, since the air conditioner system 3 starts to be adjusted in accordance with the user's boarding time, the temperature in the passenger compartment is set to the target temperature desired by the user in accordance with the scheduled boarding time while reducing the power consumption of the air conditioner system 3. Can be adjusted.

  Furthermore, since the air conditioner system 3 starts to be adjusted in accordance with the scheduled boarding time, even when the amount of power stored in the battery 5 is small, the user does not care about the boarding time and matches the scheduled boarding time set by the user. Get on. That is, user convenience is improved.

  The best mode for carrying out the present invention has been described above with reference to the embodiments. However, the present invention is not limited to these embodiments, and is described above without departing from the gist of the present invention. Various modifications and substitutions can be made to the embodiments.

  For example, in the first and second embodiments, the air conditioner system 3 may perform air conditioning control in accordance with the vehicle type such as a gasoline vehicle, an electric vehicle, a hybrid vehicle that uses gasoline and electricity in combination.

  Specifically, when the vehicle air conditioner 1 is mounted on a gasoline vehicle, the remaining amount of gasoline in the tank is detected by a remaining amount sensor and transmitted to the ECU 9. When the remaining amount of gasoline detected by the remaining amount sensor is small (below a predetermined amount), the ECU 9 drives only the blower device until the temperature in the vehicle interior detected by the indoor temperature sensor 11 decreases (below the predetermined temperature). When the ECU 9 determines that the temperature inside the vehicle compartment detected by the room temperature sensor 11 has become equal to or lower than the predetermined temperature, the ECU 9 drives the air conditioner to the target temperature set by the target temperature setting means 9a. Thereby, in the gasoline vehicle when the remaining amount of gasoline is small, the consumption amount of gasoline is reduced, and the optimal control of the air conditioner system 3 according to the situation becomes possible.

  In addition, when the vehicle air conditioner 1 is mounted on an electric vehicle, the air conditioner system 3 preferentially uses only a heating device that warms the vehicle interior without driving an air conditioner (compressor) having a dehumidifying function in the vehicle interior. To increase the temperature in the passenger compartment to the target temperature. As a result, in an electric vehicle with limited power consumption, the temperature in the passenger compartment can be raised to the target temperature while suppressing power consumption in the battery 5.

  The present invention can be used for a vehicle air conditioner. The appearance, weight, size, running performance, etc. of the vehicle to be mounted are not limited.

It is a figure which shows the outline of the system configuration | structure of the vehicle air conditioner which concerns on the 1st and 2nd embodiment of this invention.
