(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a block diagram schematically showing the overall configuration. In FIG. 1, a wiper ECU 1 drives a wiper 2 in response to a wiper operation, and notifies a processing unit (corresponding to a suggestion unit, an activation unit, and an editing unit) 3 of a wiper operation history indicating an operation state of the wiper 2. . The rain sensor 4 detects the presence / absence of water droplets attached to the windshield of the vehicle and notifies the processing unit 3 of raindrop presence / absence information. A thermometer (corresponding to detection means) 5 detects the temperature in the passenger compartment and notifies the processing unit 3 of it. A hygrometer (corresponding to detection means) 6 detects the humidity in the passenger compartment and notifies the processing unit 3 of it. The clock 7 notifies the processing unit 3 of time information indicating the current time. The ignition switch 8 notifies the processing unit 3 of a power supply ON / OFF signal indicating the ON / OFF state of the main power supply by the ignition switch.

  The personal identification device 9 has personal information for identifying a driver (occupant), for example, an identification code for a seat position memory, an IC chip built-in license storing personal information, a person identification by a camera, and personal identification information. The personal information acquired from the wireless key or the like is notified to the processing unit 3.

The communication terminal 10 acquires the weather information about the surrounding area, the destination, and the traveling direction transmitted from the information center 11 and notifies the processing unit 3 of the weather information.
The service selection / operation switch 12 includes a steering switch, a remote operation switch provided on the center console, a touch switch on a display unit provided on the instrument panel, a remote control switch, and the like. Notify the processing unit 3.

The presentation device 13 includes a display and a speaker. The presentation device 13 receives and displays a video signal from the processing unit 3 and switch operation / editing screen information and provides voice guidance.
The in-vehicle devices include an air conditioner and a power window. The air conditioner ECU 14 and the power window ECU 15 control the air conditioner and the power window, respectively, according to a control signal from the processing unit 3.

The operation history database 16 stores a wiper operation history from the wiper ECU 1 through data communication with the processing unit 3.
As will be described later, the vehicle interior state / operation condition database 17 includes a vehicle interior state definition table and an operation state indicating a correspondence relationship between the vehicle interior state and the in-vehicle device to be activated and the operation state of the in-vehicle device in relation to the present invention. A definition table is stored.
As will be described later, the processing unit 3 determines the in-vehicle device to be activated based on information from each device and the operating conditions of the in-vehicle device and proposes them to the driver. When the proposal is accepted, the determined operating conditions So start the in-vehicle device.

Now, the processing unit 3 is activated when the ignition switch is turned on.
2 and 3 show the activation service process of the processing unit 3. 2 and 3, the processing unit 3 first measures the vehicle interior temperature and humidity with the thermometer 5 and the hygrometer 6 (A 1) and then stores them in the vehicle interior state / operating condition database 17. The current vehicle interior state is determined based on the existing vehicle interior state definition table (A2).

  FIG. 4 shows an example of the vehicle interior state definition table. As shown in FIG. 4, the vehicle interior state is defined by a matrix of temperature and humidity, and is indicated by a state Snn (n is a positive number). Specifically, when the vehicle interior humidity is 50 to 60% RH and the vehicle interior temperature is 35 ° C., it is determined as “state S21”.

The processing unit 3 determines the in-vehicle device to be activated and its operation condition stored in the operation state definition table corresponding to the vehicle interior state (A3).
FIG. 5 shows an example of the operation state definition table. FIG. 5 shows the operating conditions of the air conditioner and the power window when the humidity in the passenger compartment is 50 to 60% RH in the passenger compartment state definition table shown in FIG. In this example, with respect to the air conditioner, the operating conditions are defined such that the inside / outside air switching is switched from inside air to outside air with the inside temperature of the vehicle interior being 40 ° C., and the set temperature is set lower as the temperature inside the vehicle interior is higher. . As for the power window, the operating conditions are defined so that the number of power windows to be opened increases as the temperature in the passenger compartment increases. Specifically, when it is determined as “state S21” in the vehicle interior state definition table, it is determined to switch the inside / outside air switching of the air conditioner to the inside air, and set the set temperature to 22 ° C., and the driver's seat and the assistant It decides to keep the rear seat power window closed while opening the seat power window. Such operating conditions are set for the purpose of quickly eliminating the high temperature state regardless of the vehicle interior temperature.

  The processing unit 3 detects the presence / absence of rain based on the raindrop presence / absence state from the rain sensor 4 (A4). When the processing unit 3 determines that it is raining (A5: YES), it starts “Wind OPEN” The condition is deleted (A6). Thereby, the malfunction of opening a power window at the time of rain can be prevented.

  Next, the in-vehicle device and the operating conditions determined as described above are proposed to the driver (occupant) by the presentation device 13 (A7), the timer is set (A8), and the proposal is accepted (A9) or rejected. It is determined whether it has timed out (A14) or timed out (A15). That is, a “YES” button and a “NO” button are displayed on the display unit, and it is determined which button is touched.

When the driver accepts the proposal by touching the “YES” button (A9: YES), the vehicle-mounted device to be activated is activated under the proposed operating condition (A10). Assuming that the current vehicle interior state is “state S21”, based on the operation condition definition table shown in FIG. 5, the air conditioner ECU 14 sends a control signal for setting the set temperature to 22 ° C. In addition, a control signal for opening the windows of the driver seat and the passenger seat is transmitted to the power window ECU 15. Thereby, in the state which air-conditioner ECU14 switched inside / outside air switching to inside air, the temperature of blowing air is adjusted so that setting temperature may be set to 22 degreeC. At the same time, the power window ECU 15 opens the windows of the driver seat and the passenger seat.
By the operation as described above, the interior of the vehicle is cooled by the cool air from the air conditioner, and at the same time, the sultry air in the interior of the vehicle is exhausted from the window on the driver's seat and the passenger seat to the outside of the vehicle.

  The processing unit 3 measures the cabin temperature and humidity (A11), determines whether the heat of steam has been eliminated (A12), and if it is eliminated (A12: YES), sets the air conditioner and power window to the original settings. A control signal to be returned is transmitted to the air conditioner ECU 14 and the power window ECU 15 (A13). Thereby, the setting of the air conditioner is restored to the original setting, and the window is restored to the original open / closed state.

  On the other hand, when the driver rejects the proposal of the processing unit 3 before time-out (A14: YES), the number of rejections is counted (A17). When the driver times out without refusing (A15: YES), it is determined that the driver has rejected, the timer is reset (A16), and the number of times of rejection is counted (A17).

  If the number of rejections is counted in this way, it is determined whether the number of rejections is within a specified value (A18). In this case, in the case of the first refusal by the driver, the number of refusals is 1, so it is determined that it is within the specified value (A18: YES), and the conditions are automatically updated (A26). For example, if it is temperature, it is set to change the temperature by a predetermined temperature within the range of set value ± 5 ° C. If the current position detected by the car navigation device is a cold region, the proposed temperature is increased, In the case of a warm area, lower the suggested temperature.

  The conditions automatically updated in this way are reflected at the time of the proposal by the next processing unit 3, and when the proposal is further rejected at that time, the conditions are further automatically updated. That is, the proposed temperature rejected for the first time is determined not to match the driver's preference, and the temperature is further changed. As such automatic update, the temperature difference that has been automatically updated last time may be further changed, or the proposed temperature may be changed to be a temperature difference that is opposite to the initial proposed temperature. May be.

  When the number of refusals at the time of the proposal exceeds the specified value (A18: NO), the processing unit 3 determines that it is difficult to match the driver's preference by automatically updating the conditions, and proposes condition editing. (A19), a timer is set (A20), and it is determined whether the driver has accepted the proposal (A21), rejected (A22), or timed out (A23). When the driver accepts the editing proposal (A21: YES), the condition is changed based on the editing result by the driver (A27). That is, the operating condition definition table shown in FIG. 5 can be changed. Therefore, from now on, it will be proposed to satisfy the driver's favorite conditions.

When the driver rejects the condition editing proposal regardless of the condition editing proposal (A22: YES), it is determined that it is difficult to reflect the driver's preference, and the operation condition is erased ( A25). Similarly, when the driver times out without refusing (A23: YES), it is determined to be refusal and the timer is reset (A24), and then the operating condition is deleted (A25).
With the above operation, the conditions proposed to the driver can be made as close as possible to the driver's preference, and it is possible to prevent continuous unnecessary proposals.

  According to such an embodiment, the processing unit 3 measures the current temperature and humidity in the vehicle interior, determines the in-vehicle device to be activated and the operating state of the in-vehicle device based on the measurement result, and operates. Only when the driver makes a proposal and accepts the proposal, the proposed in-vehicle device to be activated is activated under the operating conditions of the in-vehicle device, so that the driver's intention can be reflected. Therefore, unlike the conventional example in which the vehicle air conditioner and the power window are automatically activated according to the cooling load in the passenger compartment, the in-vehicle device is installed so that the passenger compartment environment is comfortable while respecting the driver's intention. Can be controlled.

Further, when the driver rejects the proposal, the operating condition is automatically updated and the changed operating condition is proposed at the next startup, so that it is possible to match the startup condition desired by the driver.
In addition, if the number of rejected proposals by the driver exceeds the specified value, it is determined that automatic updating cannot meet the driver's preference, and the driver proposes condition editing, and the driver accepts the proposal. When the condition is edited, the condition is changed based on the editing result, so that the proposal can be changed to the driver's preference.

(Second embodiment)
Next, a second embodiment of the present invention will be described with reference to FIGS. The second embodiment is different from the first embodiment in that the operation of the processing unit 3 is different, and is characterized by estimating the heat of the passenger compartment without using a hygrometer. In this embodiment, the processing unit 3 operates intermittently and stores the temperature in the passenger compartment as time passes. In this embodiment, the processing unit 3 functions as an estimation unit, and the rain sensor 4 functions as a detection unit.
FIG. 6 is a flowchart showing the operation of the processing unit 3. In FIG. 6, the processing unit 3 monitors the door state of the driver's seat (B1), and determines whether the driver's seat door is opened or closed (B2).

When the driver gets into the vehicle and opens and closes the driver's seat door, the processing unit 3 determines “YES” in step B2, and monitors the state of the driver with a seating sensor (not shown) or a driver monitoring camera (B3). ), It is determined whether the driver has boarded (B4). When it is determined that the driver has boarded the vehicle (B4: YES), the wiper operation history immediately before getting off is collected from the operation history database 16 (B5). If the wiper was not operating immediately before the previous disembarkation (B6: NO), the operation is terminated as it is, and if the wiper was operating (B6: YES), the weather before dismounting is estimated to be rain (B7).
Next, after collecting the accumulated time and temperature transition data until just before re-boarding (B8), the sultry heat in the passenger compartment is estimated (B9), and the in-vehicle device to be started and the operating conditions of the in-vehicle device are determined ( B10).

FIG. 7 shows an example of a definition table for the state of the passenger compartment according to temperature and humidity. As shown in FIG. 7, the vehicle interior state is defined by a matrix of temperature and humidity, and is indicated by a state Snn (n is a positive number). In this case, the higher the vehicle interior temperature is, the longer the accumulated time until re-boarding is, the more it is estimated that the steaming heat in the vehicle interior increases, and the in-vehicle device that starts up so as to eliminate the estimated steaming heat in a short time The operating conditions for in-vehicle equipment are determined.
Although not shown in the flowchart, the processing unit 3 estimates the vehicle interior state based on the vehicle interior definition table shown in FIG. 7 when the vehicle interior temperature reaches a specified temperature (for example, 20 ° C. or higher). It is like that.

In addition, when the temperature in the passenger compartment fluctuates and the state in which the temperature is low for a certain period of time before re-boarding continues, it is estimated that the heat of sultry has been eliminated. That is, the processing unit 3 constantly detects the temperature in the passenger compartment, and as shown in FIG. 8, after the driver gets off, the state of 20 ° C. or higher continues for 60 minutes, but then the temperature decreases, If the state below 20 ° C. (corresponding to the state SO3 shown in FIG. 7) has continued for 60 minutes, it is estimated that the heat of steam has been eliminated.
Subsequent operations are the same as those after step A7 in FIG. 2 in the first embodiment, and a description thereof will be omitted.

  According to such an embodiment, when it is estimated that it was raining when the driver got off, the heat of the passenger compartment was estimated based on the relationship between the accumulated time until the re-ride and the temperature. Therefore, even if no humidity sensor is provided, the present invention can be implemented.

The present invention is not limited to the above embodiments, and can be modified or expanded as follows.
When proposing to the driver the in-vehicle device to be started and the operating conditions of the in-vehicle device, the correction may be made based on the current season or time. That is, when the season is winter, correction is made so that the proposed temperature is high, and when the season is summer, correction is made so that the suggested temperature is low. Further, correction is made so that the proposed temperature is low during the daytime, and correction is performed so that the proposed temperature is high during the nighttime.

The driver's preference may be learned, and one or both of the vehicle interior state definition table and the operation condition definition table may be automatically edited.
You may make it suggest an in-vehicle apparatus and its operating condition for every driver | operator, or permit editing.
