Abstract

PROBLEM TO BE SOLVED: To provide an angle controller for a vehicular mirror provided with a canceling mechanism capable of canceling control of a mirror angle interlocked with an outer signal without installing additional switches. SOLUTION: When a shift lever of a vehicle is put into reverse gear and a reverse signal (the outer signal) is provided, a motor M3 for vertical motion of a left side mirror 3 is tilted downward for automatically adjusting it so that a rear wheel part vicinity comes into view of the left side mirror 3. When one of a switch 8 for vertical tilting or a switch 7 for horizontal tilting is operated during or after this tilting, a cancel signal is outputted for operating the mirror angle so that it returns to its original angle (normal position). Even if the reverse signal is provided hereafter, a tilting operation interlocked with this is not performed. In other words, the interlocked operation can be cancelled. After the next operation, when the switch 8 for vertical tilting or the switch 7 for horizontal tilting is operated during inputting of the reverse signal, the interlocked operation is reset.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle mirror angle control device having a function of tilting a mirror surface angle of a vehicle mirror to a desired set position in conjunction with an external signal. The present invention relates to a mechanism for canceling an interlocking operation.

2. Description of the Related Art Generally, a door mirror mounted on a vehicle,
An angle control device is mounted on a fender mirror or the like in order to adjust a tilt angle of a mirror surface by operating a remote controller. The angle control device includes a left / right mirror selection switch for selecting the left / right mirror, a vertical tilt switch for tilting the mirror angle in the vertical direction, and a left / right tilt switch for tilting the mirror angle in the left / right direction. Has,
For example, by operating the up / down tilt switch while the right mirror is selected by the left / right mirror selection switch, the mirror surface angle of the right mirror can be tilted in the up / down direction. Therefore, by arbitrarily operating the left / right mirror selection switch, the up / down tilt switch, and the left / right tilt switch, the mirror surface angle of the door mirror or the fender mirror can be adjusted to any position by remote control operation.

[0003] When the vehicle is moved backward to make it closer to the side of the road, the rear wheels of the vehicle are arranged to prevent the rear wheels on the passenger side (left side of the vehicle) from coming into contact with the curb. It is desirable to place the neighborhood in the field of view of the mirror. However, in order to bring the vicinity of the rear wheel part into the field of view of the mirror, it is necessary to hold down the above-mentioned vertical tilt switch for a certain period of time. There is a drawback that the operation is troublesome because it is necessary to return to the inclination angle of.

[0004] In recent years, for example,
-95846 CD-ROM (hereinafter referred to as Conventional Example 1)
As described in, when the shift lever of the vehicle is engaged in the reverse gear, by automatically tilting the mirror surface angle downward in conjunction with this reverse signal,
An angle control device has been devised, which is capable of automatically returning the mirror surface angle to the original angle when the reverse gear is released, so that the vicinity of the rear wheel portion can be brought into the field of view of the mirror, and has been put into practical use.

[0005] With the angle control device having such a function, when the vehicle is moved backward, the vicinity of the rear wheel portion can be automatically brought into view, and when the vehicle is completely moved backward,
Since the mirror angle automatically returns to the original angle, there is an advantage that troublesome operation is not required and operability is good.

However, in the above-described prior art example 1, when the shift lever is engaged with the reverse gear, the mirror surface angle is inevitably tilted downward, and the vicinity of the rear wheel portion of the vehicle becomes a mirror. Since it operates so as to enter the field of view, there is a disadvantage that it is troublesome for a driver who does not need such an interlocking operation function. In order to solve this, a mode selection switch for switching between interlocking and non-interlocking with the reverse gear closing operation is installed, and when this mode selection switch is turned on, the interlocking operation is performed and the mode selection switch is turned off In such a case, a method of canceling the interlocking operation can be easily considered.

However, in such a method, it is necessary to newly install a mode selection switch, and a space for mounting the switch near the driver's seat is required.
In addition, there is a disadvantage that extra time is required for mounting the switch.

On the other hand, for example, when entering the main lane from the acceleration lane of the highway while driving a vehicle, it is desired to widen the visual field on the right side for safety confirmation.
However, it is not easy to change the mirror surface angle by operating the above-described angle adjusting device when entering the expressway so as to widen the right visual field. Therefore, from the past, the actual opening 5
8-29540 microfilm (hereinafter referred to as Conventional Example 2)
), The signal when the turn signal of the vehicle is turned on is detected, and the mirror surface angle of the rearview mirror is automatically inclined in the left-right direction to widen the field of view on the right side. Something like that has been proposed.

However, in the method for adjusting the mirror surface angle described in the conventional example 2, when the turn signal is turned on, the mirror surface angle is obliged to incline rightward as in the conventional example 1 described above. The operation is troublesome for a driver who does not need such an interlocking operation.

[0010]

As described above, in the conventional angle control device for a vehicle mirror, regardless of the driver's preference, a signal for turning on the reverse gear or a signal for turning on the turn signal (these signals are used as signals). (Referred to as an external signal) automatically operates such that the mirror angle of the rear-view mirror or the fender mirror is inclined. Therefore, it is very troublesome for a driver who does not need such an interlocking operation. Was. In order to solve this problem, a method of installing a mode selection switch for turning on / off the input of an external signal can be easily considered. However, in this method, installation of the mode selection switch requires time and effort. Problems such as the necessity of space are required.

SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem, and an object of the present invention is to interlock with an external signal by a simple method without mounting a new switch. An object of the present invention is to provide an angle control device for a vehicle mirror provided with a cancel mechanism capable of canceling an operation.

[0012]

According to a first aspect of the present invention, a switch for selecting a right and left mirror, a switch for tilting up and down, and a switch for tilting left and right are mounted. By operating a switch and a switch for tilting left and right, a function to adjust the mirror surface angle of the vehicle mirror on the side selected by the switch for selecting left and right mirrors is provided, and when an external signal is given,
In conjunction with the external signal, the mirror angle is inclined to a desired set position, and when the external signal is stopped, the mirror for the vehicle is set to have an interlocking operation for controlling the mirror angle to return to the normal position. In the angle control device, the external signal is given, after the tilt of the mirror surface angle in the set position direction is started, when the vertical tilt switch, at least one of the horizontal tilt switch is turned on, The mirror surface angle is returned to the normal position, and the subsequent interlocking operation is released. The next time the external signal is input, when at least one of the up / down tilt switch and the left / right tilt switch is turned on, the interlocking is performed. The feature is to return the operation.

According to a second aspect of the present invention, a switch for selecting a left and right mirror, a switch for tilting up and down, and a switch for tilting left and right are mounted, and by operating the switch for tilting up and down and tilting left and right, It has a function of adjusting the mirror surface angle of the vehicle mirror on the side selected by the left and right mirror selection switch, and when an external signal is given, works with the external signal to set the mirror surface angle to a desired value. In the vehicle mirror angle control device having a control means in which an interlocking operation for controlling the mirror surface angle to return to the normal position when the external signal is stopped is tilted to the set position and the external signal is stopped, the control means includes: When the external signal is input, the mirror angle is tilted to a set position, and when the input of the external signal is stopped, control is performed to return the mirror angle to the normal position. A drive control unit, during the input of the external signal, when at least one operation signal of the switch for tilting up and down or the switch for tilting left and right is given, outputs a cancel signal, and during the next external signal input, A cancel signal output unit that stops outputting the cancel signal when at least one operation signal of the up / down tilt switch or the left / right tilt switch is provided, wherein the drive control unit is configured to control the cancel signal At the time of output, no interlocking operation with the external signal is performed.

According to a third aspect of the present invention, the external signal is a reverse signal output when the shift lever of the vehicle is shifted to the reverse gear, or a turn signal output when the turn signal of the vehicle is turned on. Signal.

According to the present invention constructed as described above, an external signal (reverse signal or turn signal of turn signal) is supplied, and in conjunction with this, the mirror angle is in the middle of tilting toward the set position or reaches the set position. After that, if the driver operates the vertical tilt switch or the horizontal tilt switch, this operation cancels the interlocking operation, and if the mirror angle is tilting to the set position direction, the tilt stops at this position Then, the mirror angle is tilted toward the normal position and returns to the original position. When the mirror angle reaches the set position completely, the mirror angle tilts toward the normal position. Then, when an external signal is given thereafter, the tilting operation of the mirror angle linked with the external signal is not performed.

If the up / down tilt switch or the left / right tilt switch is operated while an external signal is being applied in the next and subsequent times, the interlocking operation is restored by this operation, and the mirror surface angle linked with the external signal is returned. Can be tilted. Thus, it is possible to switch between interlocking and non-interlocking with an external signal without attaching a new mode selection switch.

FIG. 2 is a functional block diagram showing the internal configuration of the main control means 10. As shown in FIG. 1, the main control means 10 includes an external signal input section 31 for inputting a reverse signal (external signal) output when the shift lever of the vehicle is engaged in the reverse gear, and an operation signal input circuit 12. An operation signal input unit 32 for inputting an operation signal output from the controller, an excitation of a relay coil RC1 mounted on the relay circuit 11,
A relay control unit 33 that controls switching of non-excitation, a drive control unit 34 that outputs a control signal to the motor drive circuit 15,
And a cancel signal output unit 35.

The cancel signal output unit 35 outputs a cancel signal when the reverse signal is input to the external signal input unit 31 and the operation signal is input to the operation signal input unit 32, and the reverse signal is output. Even if the reverse signal is input again after the cancellation, the cancel signal is continuously output. In addition, when the reverse signal and the operation signal are simultaneously supplied during the output of the cancel signal, the operation is performed to stop the output of the cancel signal.

When the reverse signal is input to the external signal input unit 31, the drive control unit 34 rotates the up / down motor M3 mounted on the left mirror 3 in the normal direction to set the mirror angle of the left mirror 3 to the set position. Drive signal to the motor drive circuit 15
And when the input of the reverse signal is stopped,
The drive signal is output to the motor drive circuit 15 so that the up / down motor M3 is reversed and the mirror surface angle of the left side mirror 3 is set to the normal position. Further, when the cancel signal is given from the cancel signal output unit 35, the control for tilting the mirror surface angle to the set position side is not performed even if the reverse signal is input. Further, when a cancel signal is given during normal rotation of the up / down motor M3 (while the motor is rotating from the normal position to the set position), the motor M3 is stopped and then reversed, and the mirror surface angle of the left mirror 3 is changed. Is controlled to return to the normal position.

The relay control unit 33 includes an external signal input unit 31
When a reverse signal is input to the relay circuit 11, an operation signal is output to the relay circuit 11 to excite the relay coil RC1. When the input of the reverse signal is stopped, the mirror surface angle of the left mirror 3 is normally After returning to the position, the output of the operation signal is stopped and the relay coil RC1 is controlled to be in a non-excited state. If the cancel signal is given while the operation signal is being output to the relay circuit 11, the operation signal is not immediately stopped and the left mirror 3
The output of the operation signal is continued until the mirror angle returns to the normal position, and then the output of the operation signal is stopped.

Further, the stabilized power supply 14 shown in FIG. 1 stabilizes the voltage supplied from the battery E1 mounted on the vehicle and supplies it to the main control means 10. Reference numeral SW1 denotes an ignition switch, which is turned on when the ignition of the vehicle is turned on. Power supply 13 for motor drive
Is connected to the motor drive circuit 15 and supplies a power supply voltage for rotating the up / down motor M3 of the left mirror 3 in conjunction with the reverse signal. Further, since the motor driving power supply 13 is directly connected to the output terminal of the battery E1, the voltage of the battery E1 is supplied even when the ignition is off.

FIG. 3 is a flowchart showing the control operation of the main control means 10. Referring to FIG.
The operation of the present embodiment will be described. Now, when the ignition switch SW1 shown in FIG. 1 is turned on, the switch 6 for selecting the left and right mirrors of the angle adjusting device 1 is operated to connect the terminal 6c.
By connecting -1 and 6b-1, and terminals 6c-2 and 6b-2, the mirror angle of the right mirror 2 can be adjusted. In this state, when the terminal 7c of the right / left tilt switch 7 is connected to the terminal 7c in order to tilt the mirror surface angle to the left, the terminal 9c of the common switch 9 is interlocked with this operation.
And 9a are connected.

Then, the voltage supplied from the battery E1 is supplied to the left and right motors M2 of the right mirror 2, and the left and right motors M2 rotate in the first direction (the direction in which the mirror surface is inclined to the left). That is, the battery E1, the ignition switch SW1, the terminal 9a, the terminal 9c, the terminal 21b,
Terminal 21c, terminal T2, motor M2, terminal T3, terminal 2
4c, terminal 24b, terminal 6b-1, terminal 6c-1, terminal 7
Current flows in the order of c, terminal 7a, and ground. As a result, the mirror surface of the right mirror 2 tilts to the left.

When the connection state of the left / right tilt switch 7 is reversed and the terminals 7c and 7b are switched to be connected, the terminals 9c and 9c of the common switch 9 are operated in conjunction with this.
b, the current flows in the opposite direction to the above,
The left and right motor M2 rotates in a direction opposite to the first direction. As a result, the mirror surface of the right mirror 2 tilts to the right.

Similarly, a left / right mirror selection switch 6, a left / right tilt switch 7, and a vertical tilt switch 8
, The motors M1 to M4 can be reversibly rotated, so that the mirror angles of the right mirror 2 and the left mirror 3 can be arbitrarily adjusted by remote control.

Here, when the driver operates the shift lever of the vehicle and shifts the shift lever to the reverse gear (reverse gear), the external signal input section 31 of the main control means 10 (FIG. 2).
) Is supplied with a reverse signal (YES in step ST1 shown in FIG. 3). In response to the input of the reverse signal, the relay control unit 33 outputs an operation signal to the base of the transistor Tr1 mounted on the relay circuit 11.

By this operation signal, the transistor Tr1
Of the relay coil RC1, a current flows through the relay coil RC1.
Is in the excited state. Thereby, the five contacts 21 to 25
The connection state is switched. That is, terminals 21c and 21
a, terminals 22c and 22a, terminals 23c and 23a, terminal 2
4c and 24a and the terminals 25c and 25a are connected (step ST2).

Here, when the cancel signal is off (NO in step ST3), the drive control section 34 of the main control means 10 outputs a drive control signal to the motor drive circuit 15. As a result, the motor drive circuit 15 controls the upper and lower motors M3 of the left mirror 3 to rotate forward for a fixed time so that the mirror surface angle of the left mirror 3 points downward. That is,
Motor drive circuit 15, terminal 23a, terminal 23c, terminal T
4, motor M3, terminal T5, terminal 21c, terminal 21a,
By passing a current through the motor drive circuit 15 in this order, the up / down motor M3 is rotated forward to control the mirror angle of the left mirror 3 to the set position (steps ST4 and ST4).
5). As a result, the mirror angle of the left mirror 3 is automatically adjusted to the set position (a position where the vicinity of the rear wheel can be visually recognized), so that the driver can easily visually recognize the vicinity of the rear wheel of the left side of the vehicle. The vehicle can be safely retracted.

Thereafter, when the shift lever is switched from the reverse gear to another position (for example, a drive gear) (NO in step ST6, YE in ST7).
S), the drive control unit 34 outputs a control signal for rotating the up / down motor M3 in the reverse direction. As a result, the motor drive circuit 15 applies a voltage in the direction opposite to the above for a certain period of time, and reversely rotates the up / down motor M3 (step ST).
8). As a result, the mirror surface angle of the left mirror 3 returns to the normal position, and the vertical motor M3 stops in this state (step ST9). Thereafter, the relay circuit 11 is turned off (NO in step ST10, ST11).

Here, when the up / down motor M3 is rotating forward in conjunction with the input of the reverse signal, or when the up / down motor M3 completes normal rotation, the mirror angle of the left mirror 3 reaches the set position. When the driver operates the left / right tilt switch 7 or the up / down tilt switch 8 (YES in step ST6) while the reverse signal is continuously given after the above (steps ST4 and ST5), FIG. Each diode D1 to D5 mounted on the operation signal input circuit 12 shown
An operation signal is supplied to the operation signal input section 32 of the main control means 10 via any of the above. For example, when the left / right tilt switch 7 is connected to the left side (a state in which the terminals 7c and 7a are connected), the voltage supplied from the battery E1 causes an operation signal via the terminals 9a and 9c of the common switch 9 and the diode D1. It is supplied to the input unit 32.

As a result, the cancel signal output section 35 outputs a cancel signal to the drive control section 34 (step ST12). When the cancel signal is given, when the up / down motor M3 is rotating forward, the drive control unit 34 stops the motor M3 and then controls the motor M3 to reverse to return the mirror angle to the normal position. . When the normal rotation of the vertical motor M3 has already been completed and the mirror surface angle of the left mirror 3 has reached the set position, the vertical motor M3
Is reversed to control the mirror surface angle of the left mirror 3 to return to the normal position (steps ST8 and ST9).

After that, even if the reverse signal is released, the cancel signal output section 35 continues to output the cancel signal. Therefore, even when the reverse signal is given next time, the left mirror 3 is operated in conjunction with the reverse signal. No operation for tilting the mirror angle to the set position is performed (step ST
3 is YES). If the reverse signal is turned off (YES in step ST13), relay circuit 11 is turned off (step ST11), and the process ends. That is, the interlocking operation with the reverse signal can be canceled.

When the driver operates either the left-right tilt switch 7 or the up-down tilt switch 8 shown in FIG. 1 while the reverse signal is given, the main control means is operated in the same procedure as described above. An operation signal is input to the operation signal input unit 32 of No. 10 (YES in step ST14).
Upon receiving the operation signal, the cancel signal output unit 35 stops outputting the cancel signal (Step ST).
15). Thus, the drive control unit 34 outputs a drive control signal to the motor drive circuit 15, so that the mirror surface angle can be switched in conjunction with the reverse signal.

That is, the driver shifts the shift lever to the reverse gear (YES in step ST1), and after the mirror surface moves downward (steps ST4 and ST5), the operation is performed by one of the switches 7 and 8 (step ST5). By turning on the cancel signal (YES in ST6), the mirror surface angle is returned to the normal position by turning on the cancel signal (step ST12) (steps ST8 and ST9). Then, when the operation by the switches 7 and 8 is performed again, the operation signal from any one of the switches 7 and 8 is input after the cancel signal is turned on (YES in step ST10) (step ST10).
(YES in 14), the cancel signal is turned off (step ST15), and the downward operation is performed again so that the mirror surface angle becomes the set position (steps ST14 and ST15).

As described above, when the shift lever is in the reverse gear, the relay circuit 11 is turned on, and the normal mirror angle adjustment by the switches 7 and 8 cannot be performed. This is a switch for switching. In other words, when the mirror surface is operating downward with the reverse signal on, or after the downward operation, the switches 7, 8
Is operated, the cancel signal is turned on. On the other hand, when any of the switches 7 and 8 is operated when the mirror surface is operating upward or after the upward operation, the cancel signal is turned off.

When the relay circuit 11 is turned on, the connection between the switches 7 and 8 and the motors M1 to M4 (see FIG. 1) is cut off.
The trouble that the mirror surface is moved by the on / off operation of the mirror and deviates from the normal position can be prevented. When the shift lever is at a position other than the reverse gear, the switches 7 and 8 can always be used as ordinary switches for adjusting the mirror surface angle.

In this way, when the reverse signal is input, by operating the right / left tilt switch 7 or the vertical tilt switch 8, the output of the cancel signal and the stop of the output are switched, and the mirror surface angle control linked with the reverse signal is turned on and off. Can be switched.

As described above, in the vehicle mirror angle control device according to the present embodiment, when the reverse signal is given, either the left / right tilt switch 7 or the up / down tilt switch 8 is operated. By doing so, it is possible to cancel the mirror angle control linked with the reverse signal, and to operate either the left / right tilt switch 7 or the vertical tilt switch 8 when the reverse signal is given next time. Thus, the cancel state can be canceled (that is, returned to the original state).

Therefore, for a driver who needs an interlocking operation, the left mirror 3 automatically tilts so that the vicinity of the rear wheel can be seen when the vehicle retreats. A driver who is extremely useful and does not need such a function can cancel the interlocking operation between the reverse gear shifting operation and the mirror surface angle switching in a simple manner, so that the driver's preference Control with a high degree of freedom in accordance with

Further, the interlocking operation can be canceled without newly providing a switch exclusively for cancellation, so that there is no need to install a switch exclusively for cancellation near the driver's seat, and space can be saved. it can. In addition, there is no need to install a cancel-only switch.

In the above-described embodiment, an example has been described in which the reverse signal obtained when the shift lever is engaged with the reverse gear is used as the external signal, and the left mirror is tilted downward in conjunction with this. However, the present invention is not limited to this. For example, when a turn signal signal is used as an external signal and a turn signal operation in the right direction is input, the mirror surface angle of the right mirror 2 is tilted to the right in conjunction with the input of the turn signal signal so as to widen the right field of view. It can be applied to other cases.

[0056]

As described above, in the vehicle mirror angle control device provided with the cancel mechanism according to the present invention, when an external signal is given, the up / down tilt switch or the left / right tilt switch is provided. By operating one of these, the interlocking operation with the external signal can be canceled, and the cancel state can be canceled. Therefore, it is possible to switch between interlocking and non-interlocking with an external signal by a simple method without mounting a new mode selection switch or the like.
