2. Description of the Related Art In a conventional vehicle, for example, at night,
When the vehicle is running with the headlights turned on and stopped at an intersection or the like, the state in which the headlights are turned on continues unless the driver intentionally performs the dimming operation. Further, when the vehicle is running in a state where the wiper is operated during rain and stopped at an intersection or the like, the continuous operation state continues unless the driver intentionally switches to the intermittent operation.

[0003]

The above-mentioned conventional structure has the following problems. At night, when you are stopping at an intersection or the like, it is not necessary to keep the headlights lit at the same level as when driving, and there is a problem that unnecessary lighting puts a large load on the battery. there were. Of course, if the driver consciously performs the dimming operation, such a problem does not occur, but not all drivers necessarily perform such an operation, and improvement thereof has been demanded.

The same applies to the wiper operation in rainy weather. That is, when the vehicle is stopped at an intersection, it is not necessary to continuously operate the wiper as when traveling, and particularly when the amount of rainfall is small. In such a case, there is no problem if the driver consciously switches to the intermittent operation, but not all drivers necessarily perform such an operation, and even in that case, unnecessary load is placed on the battery. It will cost you. Further, when the amount of rainfall is small, an unpleasant noise, which is a so-called "chattering noise", may occur, and improvement thereof has been demanded.

Further, it is determined that the vehicle is stopped on the condition that the level change of the vehicle speed signal does not change for a predetermined time or more and that at least one of the service brake and the parking brake is continuously used during the measurement time. Is preferred. Further, it is preferable to determine whether or not the service brake is used with a predetermined time delay. Even if it is determined that the vehicle is stopped, it is preferable not to switch the wiper to the intermittent operation when the washer mode is selected. Furthermore, it is preferable that the headlight be gradually dimmed to a predetermined lighting rate.

[0008]

That is, in the case of the vehicle control device according to the present invention, when it is judged that the vehicle is stopped, the headlight is dimmed and the wiper is switched to the intermittent operation. . As a result, unnecessary lighting and operation are reduced, the load on the battery is reduced, and unpleasant noise due to the operation of the wiper is reduced. Also, an automatic door lock is performed if necessary.

The vehicle control device according to this embodiment described above is
The structure shown in FIG. 2 is incorporated in a vehicle. That is, the vehicle-side harnesses 83a, 83b, 83
c, 83d, 83e, 83f, and these vehicle-side harnesses 83a, 83b, 83c, 83d, 83e, 83
A joint portion 85 is attached to f. Then, the vehicle control device according to the present embodiment is connected via the joint portion 85 and the relay harness 87. A system switch 91 is connected via another joint section 89 and a relay harness 87. By turning on / off the system switch 91, the mode in which the vehicle control device 1 according to the present embodiment is used and the conventional mode are switched. Since the system switch 91 is incorporated in the operation panel on the driver's side, the driver can arbitrarily select the system.

Next, the control contents of the vehicle control device 1 according to this embodiment will be described in detail. First, the case of controlling the operation of the wiper will be described. First, it is determined whether or not the wiper switch 23 is "LOW", and the "LOW"
In the case of "W", when the vehicle is determined to be stopped, the wiper is switched to the intermittent operation. The situation is shown in FIG. When the vehicle is running, the wiper is in continuous operation. However, "L
Since it is set to "OW", it is a continuous operation at a low speed. On the other hand, when it is determined that the vehicle is stopped, the continuous operation at the low speed is switched to the intermittent operation. This intermittent operation is, for example, an interval operation with a stop time of 2 seconds. Then, when the vehicle enters the traveling state, it immediately returns to the continuous operation at a low speed. or,
If the wiper is originally in intermittent operation,
Intermittent operation is performed with the settings shown in. However, if the intermittent timer is on the vehicle side, it follows that.

The above operation will be described with reference to the circuit of FIG. 1. First, the wiper LOW switch recognition circuit 27 determines whether or not the wiper switch 23 is "LOW", and the wiper switch 23 is "LOW". In that case, a signal of logic “1” is output to the logic circuit 29. On the other hand, whether or not the vehicle is stopped is determined as follows. First, if the vehicle is stopped, either the service brake or the parking brake is in operation, and the brake use confirmation circuit 5 discriminates this. Then, when any of the brakes is used, the determination circuit 9 outputs a signal of logic “1” to the logic circuit 19. The logic circuit 19 outputs a signal to the one-shot timer 17 and the logic circuit 21 by inputting both of the signal and the signal of logic “1” from the vehicle speed recognition circuit 75 (a signal meaning that there is no vehicle speed pulse). To do. Then, if the same state is maintained even after 5 seconds which is the set time of the one-shot timer 17, it is determined that the vehicle is stopped, and the logic circuit 21 causes the logic circuit 29 to perform a logic " 1 ”signal is output.

In this embodiment, the state of the washer motor 43 at that time is further detected to determine whether or not the washer mode is selected. And
When the washer mode is not selected, the logic “1” signal is input to the logic circuit 29 via the washer switch recognition circuit 47, the inversion circuit 49, and the one-shot timer 51. When all the above conditions are met, a signal is output from the logic circuit 29 to the one-shot timer 39, and the wiper motor 33 is output via the output circuit 69.
Is controlled to switch the wiper to intermittent operation. In addition, the wiper switch is "LOW" during such intermittent operation.
Instead, when the vehicle becomes "HIGH", the vehicle is in the traveling state, or the washer mode is selected, the continuous operation is immediately returned. In addition, even if the washer mode is initially selected and then becomes the non-selected state, the set time of the one-shot timer 51 (2 seconds) is set.
Continues its continuous operation, and then switches to intermittent operation.

Further, a detailed illustration of the above-mentioned stop determination of the vehicle is shown in FIG. In the case of the present embodiment, the stop of the vehicle speed is determined from both the vehicle speed signal and the brake signal. First, looking at the vehicle speed signal, when the state of "HIGH" or "LOW" continues for the set time of 5 seconds or more, there is no vehicle speed,
On the contrary, when the state of “HIGH” or “LOW” continues for less than 5 seconds which is the set time, the vehicle speed exists.
The set time of 5 seconds is the set time of the one-shot timer 17 described above. In FIG. 6, (T ₁ ) is less than 5 seconds and (T ₂ ) is 5 seconds. On the other hand, looking at the brake signal, the state with the brake signal is the state without the vehicle speed, and even if there is no brake signal, it is 1
If the vehicle continues for less than a second, the vehicle speed will be the same. Incidentally, (T ₃ ) in FIG. 6 is about 1 second, and (T ₄ )
Means a time longer than (T ₃ ). When it is determined that there is no vehicle speed on the vehicle speed signal side and that there is no vehicle speed on the brake signal side, the vehicle speed determination is first determined to be "no vehicle speed". That is, if only one of them has no vehicle speed, the vehicle speed determination does not result in "no vehicle speed".

Next, the control of the headlight 55 will be described. In this case, as shown in FIG. 4, the vehicle is lit at a lighting rate of 100% while the vehicle is traveling, whereas if it is determined that the vehicle is stopped, it is gradually increased. Then, the lighting rate decreases to 25% and the state is maintained (75% dimming rate). Then, when the vehicle enters the traveling state again, the lighting rate returns to 100%.
This will be described with reference to the circuit diagram of FIG. Whether or not the headlight 55 is set to "LOW" is determined by the headlight switch recognition circuit 59 based on the signal of the lighting switch 53. And headlight 55
If it is determined that is set to "LOW",
A signal of logic “1” is input to the logic circuit 61 from the headlight switch recognition circuit 59.

In addition to the above, a signal is input to the logic circuit 61 from the logic circuit 21, that is, when it is determined that the vehicle is stopped by the same action as that described above, the logic circuit 21 outputs the signal. A signal of logic “1” is input to the logic circuit 61. As a result, the dimming operation of the headlight 55 is performed via the PWM circuit 65, the output circuit 63, and the FET drive circuit 67. On the other hand, when the headlight 55 is not set to “LOW” (for example, set to “HIGH”) or the vehicle is running, such a dimming operation is performed. There is no such thing.

Next, the control of the automatic door lock will be described. This is as shown in FIG. 5, and the automatic door lock signal is output when the vehicle speed reaches 20 km / h after the vehicle has been stopped for 5 seconds or more. This will be described with reference to the circuit diagram of FIG. 1. First, a signal of logic "1" (indicating that the stopped state of the vehicle continues for 5 seconds or more) from the logic circuit 21 of the stop determination circuit 15 is R.
It is input to the S flip-flop 78. The above logic "1"
The signal of is held by the RS flip-flop 78 and input to the logic circuit 79. Next, when the vehicle speed of the vehicle reaches 20 km / h, a signal of logic "1" is input from the vehicle speed recognition circuit 77 to the logic circuit 79. As a result, the automatic door lock signal is output from the logic circuit 79 via the output circuit 81. Further, a signal is output from the logic circuit 79 to the RS flip-flop 78, whereby the hold state by the RS flip-flop 78 is released.

When the above-mentioned operation is shown by a flow chart,
As shown in FIGS. 7 to 8. In FIG.
First, when starting, initial processing is performed (sequence S1). Next, the presence / absence of vehicle speed input is determined (sequence S2). This is a process for determining whether the vehicle speed detection unit 71 is functioning normally (fail safe 1). If there is no vehicle speed input, the repeating sequence S2 is performed. On the other hand, if there is a vehicle speed input, vehicle speed sensor input processing is performed (sequence S).
3). Next, a brake input process is performed (sequence S4). Next, a write input process is performed (sequence S5). Then, wiper input processing is performed (sequence S6).

Next, it is determined whether or not the vehicle speed is 20 km / h or more. When the vehicle speed is 20 km / h or more, the automatic door lock process is performed (sequence S8). Next, it is determined whether or not the vehicle speed condition is satisfied (sequence S9) (fail safe 2. When the vehicle speed condition is satisfied, light dimming processing is performed as shown in FIG. 8 (sequence S10), and the wiper is further applied. Intermittent processing is performed (sequence S1
1) (Fail Safe 3). On the other hand, when the vehicle speed condition is not satisfied, the normal write operation (sequence S1
2) The wiper operates normally (sequence S13).

Further, in the case of this embodiment, as described above, various fail-safe configurations are adopted. That is, the following is taken into consideration when determining whether or not the vehicle is stopped. That is, there is a possibility that the vehicle speed signal may not be recognized even though the vehicle is traveling due to a failure on the vehicle side. In addition, when the road surface is wet due to rain, snow, or the like, when the brake is operated, the tires may be locked and the vehicle speed signal may not be recognized. Further, even if the engine is started, there is a possibility that the vehicle speed signal may not be recognized due to a failure on the vehicle side. That is, it is extremely dangerous to determine whether the vehicle is stopped only from the vehicle speed signal. Therefore, not only the vehicle speed signal but also the operation state of the brake is taken into consideration, and further, a predetermined set time is added to enable more safe control.

The following is a detailed description. First, it is "fail safe 1". In this case, as shown in FIG. 9, it is first determined whether or not there is a change in vehicle speed input (sequence S14). Next, it is determined whether the vehicle speed input change is three times or less (sequence S15). Through the above steps, it is determined whether or not the vehicle speed detector 71 is functioning normally. When it is not functioning normally, the dimming process and the intermittent operation process according to the present embodiment are not performed. Next, “fail safe 2” will be described. As shown in FIG. 10, it is determined whether or not there is a change in vehicle speed input (sequence S16). If there is a change in vehicle speed input, the operation prohibition is released (sequence S17), and then the vehicle speed condition is not satisfied (sequence S18). . On the other hand, when there is no change in the vehicle speed input, it is determined whether or not there is a brake input (sequence S19). When the brake input is present, it is determined that the operation is prohibited (sequence S20), and when the operation is not prohibited, it is determined whether 5 seconds have elapsed since the brake is present (sequence S2).
1). If the time has elapsed, the vehicle speed condition is satisfied (sequence S22).

If there is no brake input, it is judged whether the vehicle speed condition is not satisfied (sequence S23),
If the vehicle speed condition is not satisfied, it is determined whether or not one second has passed without a brake (sequence S24). And 1
If the second has elapsed, the operation prohibition setting (sequence S
25), the vehicle speed condition is not satisfied (sequence S26).
That is, the stop of the vehicle is discriminated from both the vehicle speed signal and the brake signal, and the safety is further enhanced by various set times.

Next, the "fail safe 3" will be described with reference to FIG. First, the presence / absence of a light switch input is determined (sequence S27). When there is a light switch input, the light dimming operation is performed (sequence S28). Next, it is determined whether or not the wiper switch is input (sequence S29). If there is a wiper switch input, the presence or absence of a washer switch input is determined (sequence S30). If there is a washer switch input, the wiper continuous operation is performed (sequence S31). If there is no washer switch input, it is determined whether or not there is a washer delay (sequence S32), and if there is a washer delay, the wiper continuous operation is performed (sequence S31). If there is no washer delay, the wiper intermittent operation starts (sequence S33). That is, the washer operation is prioritized.

As described above, according to this embodiment, the following effects can be obtained. First, when the vehicle is stopped,
Since the headlight 55 can be automatically dimmed, the load on the battery can be reduced accordingly. Further, since the wiper can be switched to the intermittent operation, it is possible to reduce the load on the battery to that extent and to reduce the generation of unpleasant noise such as so-called "chattering noise". Further, when the vehicle speed reaches a predetermined value, the automatic door lock signal is automatically output, so that traveling safety can be improved.

Further, when judging the stop of the vehicle, not only the vehicle speed signal but also the brake signal is taken into consideration. Therefore, it is possible to prevent erroneous determination that the vehicle is stopped even though the vehicle is traveling, and it is possible to improve traveling safety.
Also, regarding the intermittent operation of the wiper, when the washer mode is selected, even if the vehicle is stopped, the intermittent operation is not switched and the washer mode can be prioritized. it can. Further, in the case of the present embodiment, the configuration is not applied in the first place when the wiper is driven at "HIGH" or when the headlight 55 is lit at "HIGH". That is, in such a case, even if the vehicle stops, the state is continued as it is, unless the driver intentionally performs another operation.

The present invention is not limited to the above-mentioned embodiment. For example, in the above-mentioned one embodiment, the vehicle control device provided with all of the dimming of the headlight, the intermittent operation of the wiper, and the automatic door lock has been described as an example, but the one provided with only one of them, the two provided It may be provided. Moreover, the circuit configuration is merely an example, and the present invention is not limited to this. Further, various numerical values (dimming rate, various set times, vehicle speeds for automatic door lock, etc.) in the above-described embodiment are merely examples, and may be appropriately set. Incidentally, the dimming rate can be from 0% to 100%.

[0033]

As described above in detail, according to the vehicle control device of the present invention, when it is determined that the vehicle is stopped, the headlight is dimmed and the wiper is switched to the intermittent operation. With this configuration, it is possible to reduce unnecessary lighting and operation, reduce the load on the battery, and reduce unpleasant noise caused by the operation of the wiper. Further, since the automatic door lock is configured to be performed if necessary, the traveling safety can be improved.
