Abstract

PURPOSE:To eliminate inutile electric conduction for a car load by controlling the car load in the operation mode with a plurality of steps on the basis of the instruction signal supplied from a switch. CONSTITUTION:If an auto mode switch 4 is turned ON when a car is in stop state, a night illumination lamp system 2 is automatically switched from the headlight lighting-ON mode to the small-lamp lighting-ON mode lower by one step by the operation of a control circuit 6. When a wiper motor 1 is in HI mode or LO mode, automatic switching to LO mode or INT mode lower by one step is performed, when the wiper motor 1 is in HI mode or LO mode. Therefore, inutile electric conduction for the wiper motor 1 or the night illumination lamp system 2 is prevented, and the troublesome operation that a switch 3 must be turned ON each time when a car stops can be omitted.

After executing the above-mentioned ``loading and flag setting'' routine L2, the ``stall detection routine'', details of which are shown in FIG. 3, is executed.
After sequentially executing routine [-4, the routine reads input and sets flags and returns to step 2. Then, judgment step a1 is executed at the beginning of routine 1-3 for detecting stalling.
Then, it is determined whether the auto mode flag is "1" or not, and in the case of rNOJ (that is, when O1~mode is not selected by the auto mode selection switch 4),
After setting the "C stop state flag r1" in the 1-flag change history-1 stroke a2, the program jumps to the beginning address of the label C, that is, the 1-load control routine L4. Figure 4 shows 11 negative control.
In routine L4, first, the judgment line f! i! bx (,1 small norag is 1-1" is judged "no", f' Y

After executing step b2° of “stop mode and 1-11 mode”, return to label △.

As a result, the night illumination light system 2 is switched to the small lamp stipple mode when the small lamp flag "1" is set, and both the headlamp flag 1゛1J and the high beam flag [-1] are set. 8+! When the high beam is turned off, the headlamp flashing mode is switched to 7-mode, and when the headlamp flag is 1° 1J only, the headlamp flashing mode is switched to the 1"-beam state, and the small lamp flag and Both headlamp flags are 1-
When it is returned to "0", the light is turned off. In addition, the wiper motor 1 is
When the mode is switched to N1' mode and the LO flag 1-1 is set, the mode is switched to the LO mode and the 1-11 flag is set.
When "1" is set, the mode is switched to 1-11 mode, and when the fNT flag, LO flag, and l-11 flag are all returned to "1", the mode is stopped.

Therefore, when the auto mode selection switch 4 is turned off, the selector switch 3? By selectively setting each flag using Y, the wiper Tanabata 1 and the night illumination light system 2 can be controlled in a luminous manner.

After that, when the A-to mode selection switch 4 is turned on, the auto mode flag is changed to 11 in the 1 input reading and flag setting routine 12, as shown in FIG. Judgment step a in J11 motion detection J routine L3 It is judged as l-CI-YfESJ and the process moves to the next judgment step a3? 'illll.' In this judgment step a3, it is judged whether the stop flag is [1 or not], and if rYESJ, that is, when both lii are stopped, the auto mode selection switch 4

In culm a6, it is determined whether the 1 head lamp flag is 11 or not. If the determination step 86 determines 1-Y [SJ, in other words J, the night illumination light system 2 is in the headlamp point pair mode and the headlamp is either in the low beam state or in the high beam state. If the points were matched, change the flag by 1"? -j"4': Move to I!a r and change the headlamp flag to 1-o" and change the small lamp flag to "1", and then change the next 1 flag in step a8 to change the headlamp flag to "1-o". 1 point pair flag (hereinafter simply referred to as O1 1 point pair flag) Make a decision after setting I-IJ! jp? Move to a s a. In this judgment process alO, it is judged whether the 1'l-11' flag is (1) or not, and if the judgment result is rYEsJ, the difference in other words is that the wiper motor 1 is in the Hl mode and the wiper is performing a high-speed wiping operation.

After changing the Ol flag to "1", the process moves to label C.

Furthermore, when the "stall detection" routine L3 is repeated after this, the stall state routine is returned to [-0] in the "1-flag change" step a5, so that rN is returned in the judgment step a4.
It is determined to be OJ and the label C is set to 1, and each process is executed in the order of a1 → a3 → a4.
- is formed.

As a result of executing the "stall detection" routine L3 as described above, in the "load control" routine L4, the small lamp flag set in the "flag change" step a7 is "1".
'' and LOl flag 1 set in the ``flag change'' step 811, step down system 2 to night lighting light 1 to small lamp pair mode and avoid stepping down wiper motor 1 to LO mode. Become.

In addition, if it is determined in the judgment step a6 that the lamp is l-N OJ, in other words, if the night illumination light system 2 is in the small lamp dot or off state, the Δ-t dot flag is 1 flag change J row culm a to change rOJ,
After executing, the process moves to the judgment step alO. Follow-C1
For example, when the small run 1 flag 11 is set and the night illumination light system 2 is in the small lamp point pair mode, if the t-1 mode selection switch 4 is turned on at the timing described above, It is possible to cause a change in the point pair mode. In addition, if it is determined in the determination step alo that the wiper motor 1 is in an operation mode other than the HI mode, the process moves to determination step a12 and the "Lo flag is set to 1". ``Whether or not'' is determined in step 117i. And that judgment! If the ji result is 1-Y[S, IU, in other words, the wiper motor 1 is in the LO mode and the wiper is operating at low speed! In this case, proceed to the [Change Flags] step a13, change the 'T-to flag to 1-0', change the lN-1 hook to 1-1, and then proceed to the [Change Flags] step. INI in process ata
After setting the mode 71'-1-setting flag (hereinafter simply referred to as auto-setting flag) IiJ, the process moves to label C. Therefore, in this case, in the "load control" routine L4, the wiper motor 1 is stepped down from the LO mode to the I N T mode based on the I N T flag "1". Furthermore, if rNOJ is determined in the determination step a12, in other words, the wiper motor 1 is I N '
7 if it is in the l-'E- mode or stopped state.
1-1 to change the setting flag to 1-0" 1-Flag change" step a16 is executed, and then the process moves to label C. Therefore, for example, even if the INT flag "1" is set and the wiper motor 1 is in the INT mode, and the mode selection switch 4 is turned to O1 at the above-mentioned timing, the operation mode will not change. Does not occur.

In other words, when the A-1 mode selection switch 4 is turned on while the vehicle is stopped (stop 4H; when both 'i S d and on signal Sb are output), the night lighting When the light system 2 is in the headlamp pair mode, it is automatically switched to the small lamp lighting mode one step lower, and when the wiper motor 1 is in the 1-11 mode or LO mode, it is automatically switched one step lower. This automatic switching operation is performed when the vehicle is stopped from running while the A'-to mode selection switch 4 is turned on. 1 sequentially in judgment steps al and a3
- Since it is determined that YES J, the process is executed in the same manner as described above. Therefore, it is possible to prevent wasteful energization of the C1 wiper motor 1 and the night lighting lights 1 to 2, but in this case, it is possible to prevent unnecessary energization of the C1 wiper motor 1 and the night lighting lights 1 to 2. . In addition, when the O-I mode selection switch 4 is turned on while the vehicle is stopped, or when the vehicle is stopped with the O-I mode selection switch 4 in the A state, the night illumination light system 2 turns on the small lamp. When the sharpener and wiper motor in the INT mode are in the INT mode, their operations are maintained as they are, so there is no risk of compromising safety.

On the other hand, when the vehicle starts running from the above-mentioned stopped state, since it is determined as l'N and OJ in the determination step a3, the process moves to the determination step a16.

This judgment line f! i! In the axs, the "stop status flag is 1"
In this case, the stop state flag has been changed to "0" in the [flag change] step a5 performed when the vehicle is stopped. It is judged as rNOJ, and the process moves to the next judgment step aIB.

In this judgment step alB, it is judged whether or not the IA-to-point flag is "1", and if the judgment result is rYEsJ, in other words, the night illumination light system 2 is set to small by the above-mentioned automatic switching operation. If the mode has been stepped down to lamp lighting mode, move to "flag change" step a19?
Then change the auto lighting flag to 1゛0'', and then proceed to the next 1 flag change step a2o'C: Change the headlamp flag to 11'' and change the small lamp flag to rOJ. After this, the process moves to a judgment step a21. Further, if it is determined in the judgment step a1B that 1-N OJ, in other words, if the automatic switching operation of the lighting mode of the night illumination light system 2 is not performed, the process jumps to the judgment step a21.

In the judgment step a'21, the judgment FRi L is made as to whether the LO flag is "1" or not, and if the judgment result is rNOJ, in other words 4.
If wiper motor 1 is in a mode other than LO mode,
The process moves to the next determination step a23, where it is determined whether the 1-auto setting flag is "1" or not. If rYESJ is determined in step a23, in other words, if wiper Tanabata 1 has been stepped down to the IN 'l' mode by the automatic switching operation described above, the flag change ” Go to step a24 and set the i' A-1 setting flag to “0.”
” and then the next 1 flag change in step a26.
-07 Change lag to 111 and set INT flag to 1
After that, change the l flag to "1°" and proceed to step a'27. Also, in the judgment step a23, I' N O
In other words, if it is determined that the wiper motor 1 is
If it has not been stepped down automatically, change the flag and move to culm a17. Such "flag change" (P in culm alt) changes the movement status flag to "1", and after this, moves to label C1j
Rir. Therefore, when the "stall detection" routine L3 is repeated after this, rYEsJ is determined in the judgment step a16, and the "flag change" step a17 is skipped, and each step is changed from a1 to a3 to ale to a17. A flow is created that executes in this order. However, as mentioned above,
As a result of executing routine L3 of "stall detection", in routine La of "1-Load control", if the headlamp flag [1j is set in "flag change" step a20 (\, that is, the night illumination light system 2 is set to small lamp Based on this headlamp flag "1", the night illumination light system 2 is set to low beam mode (i.e., the original lighting mode) when the headlamp flag is automatically stepped down to In other cases, the lighting mode of the night illumination light system 2 is not changed. In addition, [Load control J routine 4]
Now, in the [°Change flag] step a25, change the L O flag to 11.
” is set (i.e. the wiper motor is
mode),
Wiper motor '1 is set to L based on the LO flag '1'.
OT need (i.e., original operating mode), in other cases (excluding when the judgment result in judgment step a21 is rYEsJ), the point pair mode of the wiper motor 1 is not changed. . If IYEsJ is determined in the determination step a21, in other words, if the wiper motor 1 is in the O mode,
Move to step 22 of “Change Flag” and change the −11 flag to “
After changing the LO flag to "1", the label C is changed through step a1□ of "1) Change r flag".
Move to i: J'fl becomes Jζ. Therefore, in this case, in the 1-load control routine L4, the wiper motor 1 is stepped up from the 10 mode to the 1-11 mode based on the 1-II fusig f' IJ.

In short, when the vehicle starts running from a stopped state (when the output signal SC of the 71-turn signal sb is output), the night illumination light system 2 returns to the original point. mode and the wiper motor 1 is automatically returned to the original operating mode, so there is no need to perform the troublesome operation of turning on the changeover switch 3 every time the vehicle starts traveling. Moreover, the night illumination light system 2 is automatically returned to the headlamp lighting mode.
Since the headlights are always returned to the low beam state, the headlights will no longer be turned on in the high beam state when the vehicle starts driving from a stopped state, thus causing a false sense of dazzle to the driver of an oncoming vehicle. There is no risk of it being lost.

In addition, when the auto mode selection switch 4 is turned on while the vehicle is running and the auto mode flag is set to "1", the stationary state flag is set to "1" in the "flag change" step a2 executed at the previous stage. °1'' is set, 1'YEsJ is set in the judgment step a1 and I-N is set in the judgment step a1 in response to the ON of the mode selection switch
As soon as it is judged as OJ and moves to judgment step a1.6,
At this point, it is judged as ``1-YES'' and the flag is changed to step a17. Therefore, in this case, there is no change in the point pair mode of the night illumination light system 2 and the operation mode of the wiper motor 1.

It should be noted that the content of the J5 Rir Microcompico and Taro Program in the above embodiment is an example of load control for a vehicle, and is of course not limited to this.

As is clear from the above description, the present invention applies to the J3 method for controlling a vehicle load having a plurality of operation modes.
Therefore, wasteful energization of the vehicle negative 6b can be prevented and the life of the battery can be extended, and such an effect can be obtained without requiring troublesome operations.
Furthermore, it has the excellent effect of improving safety.
