[0026]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a vehicle outside temperature display method according to the present invention will be described with reference to FIGS.
[0027]
FIG. 1 is a diagram showing a configuration of a main part of an outside air temperature display device that implements an outside air temperature display method according to the present invention, FIGS. 2 to 4 are flowcharts showing its operation, and FIG. 5 is a diagram showing a display mode of outside air temperature. is there.
[0028]
The outside air temperature display device shown in FIG. 1 has a control unit 1 composed of a microcomputer. The control unit 1 includes an ignition switch 2, an outside air temperature sensor 3, and a liquid crystal or fluorescent display tube provided on an instrument panel. A display 4 dedicated to the outside air temperature is connected, and the outside air temperature detected by the outside air temperature sensor 3 when the ignition switch 2 is on can be displayed on the display 4 under the control of the control unit 1. Has become.
[0029]
In the outside air temperature display device having such a configuration, in the present embodiment, the control unit 1 detects the vehicle speed signal, the engine rotation signal, the cooling fan operation signal, the A / C set temperature signal, the A / C operation signal, and the water temperature sensor 5 to detect the signal. A display mode selection switch 6 is connected to the control unit 1 to select a display mode of the outside air temperature on the display 4 while supplying a vehicle state signal indicating the vehicle state of the cooling water temperature signal to be supplied. The controller 1 controls the display of the outside air temperature on the display 4 according to the display mode selected by the display mode selection switch 6.
[0030]
In the present embodiment, as a display mode, in addition to a constant display mode in which the outside air temperature detected by the outside air temperature sensor 3 is always displayed as a number on the display 4, a setting off mode in which the outside air temperature is selectively displayed as a number , An auto mode, and a traffic congestion mode, and one of the four display modes is selected by the display mode selection switch 6, and in the three selection display modes, as necessary. The required set temperature is set by the display mode selection switch 6.
[0031]
In FIG. 1, the display mode selection switch 6 is shown by an open / close switch for simplification of the drawing. However, such a display mode selection switch 6 uses an existing switch such as a trip reset knob. By pressing or turning, it is possible to select a display mode or set a required set temperature. At this time, the display 4 displays the selected display mode and the set required set temperature so as to be understood.
[0032]
Hereinafter, the operation of the outside air temperature display device in the three selection display modes will be described with reference to flowcharts shown in FIGS. 2 to 4 and a display mode shown in FIG.
[0033]
FIG. 2 is a flowchart showing a display operation in the setting off mode. In the setting off mode, first, the setting mode is selected by the display mode selection switch 6 (step S1), and then the first set temperature T1 at which the display of the numerical value of the outside air is interrupted is set to the desired value by the display mode selection switch 6. (For example, 25 ° C.) (Step S2).
[0034]
Thereafter, the control unit 1 compares the outside air temperature T detected by the outside air temperature sensor 3 with the first set temperature T1 (step S3), and when T ≦ T1 (No), FIG. ), The outside air temperature T is numerically displayed on the display 4 (step S4), and when T> T1 (Yes), as shown in FIG. The numerical display of the temperature T is interrupted (turned off), and the character "OFF" indicating that the display of the outside air temperature is interrupted is displayed on the display 4 (step S5).
[0035]
Thereafter, in step S6, it is detected whether or not the setting-off mode has been released. If the setting-off mode has not been released (in the case of No), the process returns to step S3 and the above operation is repeated. ), The mode shifts to the constant display mode (step S7).
[0036]
As described above, in the set-off mode, when the outside air temperature T detected by the outside air temperature sensor 3 exceeds the first set temperature T1, the numerical display of the outside air temperature T is automatically interrupted, and the outside air temperature T becomes the first set temperature. When the temperature becomes equal to or lower than T1, the numerical display is automatically restored. Therefore, when the outside air temperature T exceeds the first set temperature T1, the driver does not need to recognize the outside air temperature T as a number. Therefore, it is possible to prevent the driver from feeling annoying, uncomfortable, or frustrated due to an increase in the outside air temperature.
[0037]
In addition, while the numerical display of the outside air temperature T is interrupted, the character "OFF" is displayed on the display 4, so that the driver only recognizes that the outside air temperature T exceeds the set temperature T1. It is possible to prevent the outside temperature sensor 3 and the display 4 from being erroneously recognized as having failed.
[0038]
Further, since the first set temperature T1 is set to a desired value by the display mode selection switch 6, the outside air temperature can be appropriately displayed according to the driver's temperature sensation or the like. Note that the first set temperature T1 may be fixedly set in advance.
[0039]
FIG. 3 is a flowchart showing the display operation in the auto mode. In the auto mode, first, the auto mode is selected by the display mode selection switch 6 (step S11).
[0040]
Thereafter, the controller 1 compares the outside air temperature T detected by the outside air temperature sensor 3 with a second set temperature T2 (for example, 25 ° C.) (Step S12), and when T ≦ T2 (No) Displays a numerical value of the outside air temperature T on the display 4 as shown in FIG. 5A (step S13).
[0041]
On the other hand, if T> T2 in Step S12 (Yes), it is next detected whether or not the A / C is operating based on the A / C operation signal (Step S14). When C is not operating (in the case of No), a third set temperature T3 (for example, 30 ° C.) equal to or higher than the second set temperature T2 is compared with the outside air temperature T (step S15), and T ≦ T3 In the case of (No), the process proceeds to step S13, and the outside air temperature T is numerically displayed on the display 4, and when T> T3 (Yes), the display is performed as shown in FIG. 5 (b). The numerical display of the outside air temperature T on the display unit 4 is interrupted (turned off), and the character "OFF" indicating that the display of the outside air temperature is interrupted is displayed on the display unit 4 (step S16).
[0042]
Therefore, when the A / C is off, the outside air temperature T is displayed as a number up to 30 ° C., and turns off when the temperature exceeds 30 ° C.
[0043]
On the other hand, in step S14, when the A / C is operating (in the case of Yes), the A / C set temperature Tc is read from the A / C set temperature signal, and the outside air temperature T and the A / C set are read. A difference (T-Tc) from the temperature Tc is calculated (step S17), and the calculation result is compared with a fourth set temperature T4 (for example, 5 ° C.) (step S18), and (T-Tc) ≦ T4. When (No), the process proceeds to step S13, and the outside air temperature T is displayed on the display 4 as a number. When (T−Tc)> T4 (Yes), the process proceeds to step S16 and displayed. The numerical display of the outside air temperature T on the display unit 4 is interrupted (turned off), and the character “OFF” indicating that the display of the outside air temperature is interrupted is displayed on the display unit 4.
[0044]
Thereafter, in step S19, it is detected whether or not the auto mode has been canceled. If the auto mode has not been cancelled (No), the process returns to step S12 to repeat the above-described operation, and if the auto mode has been canceled (Yes). Then, the mode shifts to the constant display mode (step S21).
[0045]
Therefore, when the A / C is on, the outside air temperature T is displayed as a number up to 25 ° C., and when it exceeds 25 ° C., the difference (T−Tc) between the outside air temperature T and the A / C set temperature Tc is displayed. ) Up to 5 ° C., the numerical value of the outside air temperature T is displayed. When the difference (T−Tc) between the external air temperature T and the A / C set temperature Tc exceeds 5 ° C., the numerical display of the outside air temperature T is turned off.
[0046]
As described above, in the auto mode, the numerical display of the outside air temperature T is automatically interrupted when the outside air temperature T exceeds the third set temperature T3 when the A / C is off according to the operation state of the A / C. When the difference between the outside air temperature T and the A / C set temperature Tc exceeds the fourth set temperature T4 when the A / C is on, the numerical display of the outside air temperature T is automatically interrupted. In the ON state of / C, the driver does not care about the outside air temperature, and the driver's mental state can be stabilized in a comfortable environment of the desired A / C set temperature Tc. it can.
[0047]
Also, in this case, the character "OFF" is displayed on the display 4 while the numerical display of the outside air temperature T is interrupted, so that the driver is merely informed that the outside air temperature T exceeds the set temperature. Can be recognized, and it can be prevented that the outside temperature sensor 3 and the display 4 are erroneously recognized as having failed.
[0048]
In the above-described auto mode, the set temperatures of the second set temperature T2, the third set temperature T3, and the fourth set temperature T4 may be fixedly set in advance, or the display mode selection switch 6 Thus, it is possible to appropriately display the outside air temperature according to the driver's sense of temperature or the like. Further, the third set temperature T3 can be set to the same temperature as the second set temperature T2.
[0049]
FIG. 4 is a flowchart showing a display operation in the traffic jam mode. In this congestion mode, first, the congestion mode is selected by the display mode selection switch 6 (step S21).
[0050]
Thereafter, the controller 1 compares the outside air temperature T detected by the outside air temperature sensor 3 with a fifth set temperature T5 (for example, 25 ° C.) (Step S22), and when T ≦ T5 (No) Displays a numerical value of the outside air temperature T on the display 4 as shown in FIG. 5A (step S23).
[0051]
On the other hand, when T> T5 in Step S22 (when Yes), the vehicle speed v and the engine speed r are read from the vehicle speed signal and the vehicle state signal of the engine speed signal (Step S24), and the vehicle speed v It is determined whether or not the engine speed is equal to or less than a predetermined speed (for example, v ≦ 10 km / h) or the engine speed r is equal to or less than the predetermined speed (for example, r ≦ 500 rpm) for a set time t (for example, 5 minutes) (step S25) If it does not continue (if No), the process proceeds to step S23, where the outside air temperature T is numerically displayed on the display 4, and if it continues (if Yes), that is, during traffic jam or when the vehicle is stopped, FIG. As shown in FIG. 5B, the numerical display of the outside air temperature T on the display 4 is interrupted (turned off), and the character "OFF" indicating that the outside air temperature display is interrupted is displayed on the display 4 (step). S2 ).
[0052]
Thereafter, in step S27, it is detected whether or not the congestion mode has been released. If the mode has not been released (No), the process returns to step S22 to repeat the above operation. ), The mode shifts to the constant display mode (step S28).
[0053]
As described above, in the traffic jam mode, when the outside air temperature T exceeds the fifth set temperature T5 and the vehicle speed v is equal to or less than the predetermined speed, or the predetermined vehicle state in which the engine speed r is equal to or less than the predetermined speed continues for the set time t. Automatically interrupts the numerical display of the outside air temperature T, so that the numerical display of the outside air temperature can be interrupted when the temperature display is anxious, such as during a traffic jam under hot weather, It is possible to prevent annoying, unpleasant, or frustrating feelings caused by the outside air temperature.
[0054]
Also, in this case, the character "OFF" is displayed on the display 4 while the numerical display of the outside air temperature T is interrupted, so that the driver simply needs the outside air temperature T to exceed the fifth set temperature T5. Can be recognized only, and it can be prevented that the outside air temperature sensor 3 and the display 4 are erroneously recognized as having failed.
[0055]
In the traffic jam mode, the fifth set temperature T5 and the set time t, or the set temperatures of the vehicle speed v and the engine speed r may be fixedly set in advance, or the display mode selection switch 6 may be used. Thus, the outside air temperature can be appropriately displayed in accordance with the driver's sense of temperature and the desired vehicle state.
[0056]
Also, instead of the vehicle speed v and the engine speed r, it is determined from the cooling water temperature, the number of temperature rises thereof, or the operation of the cooling fan whether the vehicle is congested or stopped, or any one of these vehicle state signals. The display of the outside air temperature T can be controlled in the same manner by judging whether the vehicle is congested or stopped from two or more arbitrary ones.
[0057]
The present invention is not limited to the above embodiment, and can be variously modified without departing from the spirit of the invention. For example, in the above-described embodiment, the present invention is applied to a case where the outside air temperature is high. However, the present invention can be applied to a case where the temperature is lower than a set temperature below the freezing point, or both a high temperature and a low temperature.
[0058]
While the display of the numerical value of the outside air temperature T is interrupted, the display is not limited to the “OFF” display, but may be related to the outside air temperature, for example, a picture mark as shown in FIGS. And mark information such as a thermometer mark as shown in FIG. 7 and character information such as "HOT" and "COLD" as shown in FIGS. 7 (a) and 7 (b). By doing so, the driver can blur the outside air temperature exceeding the set temperature and make it vaguely recognized, and the outside air temperature display is switched from the numerical display to the mark information display or the character information display, so that the driver can be provided to the driver. The display can be interesting.
[0059]
Furthermore, the present invention can be applied not only to the case where the outside air temperature is displayed on a dedicated display, but also to the case where the display is shared with the display of other vehicle information to switch and display the outside air temperature. In this case, when the outside air temperature exceeds the set temperature in the display state of the outside air temperature, the numerical display is automatically interrupted, so that the driver does not need to perform an extra display switching operation.
[0060]
【The invention's effect】
As described above, according to the outside air temperature display method of the present invention, when the outside air temperature becomes higher or lower than the set temperature, the numerical display of the outside air temperature is automatically interrupted. Even in the case of the switching display method, it is possible to avoid the driver from directly recognizing the outside air temperature as a number without forcing any operation, and to give the driver a feeling of discomfort, discomfort, or irritation due to the outside air temperature. Can be prevented.
