[0001]

BACKGROUND OF THE INVENTION The present invention reciprocates the right and left door mirrors of a motor vehicle between a retracted position parallel to the door and a return position orthogonal to the door. The present invention relates to a control apparatus for an automobile door mirror.

[0002]

2. Description of the Related Art In an automobile using a door mirror as an outer mirror, a door mirror protruding from a door often obstructs the parking of the automobile. For this reason, the door mirror is configured to be reciprocally rotatable between a storage position parallel to the door and a return position orthogonally protruding from the door (a use position in a normal state). ing.

In particular, in recent years, as the value of automobiles has increased, the rotation of the door mirror between the retracted position and the return position has been electrified, and the rotation of the electric door mirror can be controlled by remote control. In such a device, the left and right door mirrors are configured to rotate in synchronization with each other. In recent years, in order to reduce the number of required wire harnesses, a multiplex communication system has been employed for transmitting a signal for controlling the rotation of a door mirror and the like. The control circuit which is the core of the above is configured by a microcomputer.

FIG. 4 shows an example of a control device in which rotation control of a door mirror is performed using a microcomputer.

FIG. 4 shows a circuit configuration relating to, for example, a door mirror on the driver's seat side.
The motor 1 reciprocates the door mirror on the driver's seat side between the retracted position and the return position according to the forward / reverse rotation. The first relay 2 having the exciting coil 2a and the transfer type relay switch 2b is operated through the transistor 4 by the control circuit 3 composed of a microcomputer. The second relay 5 having the exciting coil 5a and the transfer type relay switch 5b is operated by the control circuit 3 through the transistor 6.

In this case, the current path of the motor 1 is formed from the power supply terminal + B via the above-mentioned relay switches 2b and 5b. When an energizing path for rotation is formed and the door mirror is rotated in the storage position direction, and when the second relay 5 is operated, an energizing path for reversely rotating the motor 1 is formed and the door mirror is rotated in the direction of the return position. Be moved.

The return position detection switch 7 is configured to turn on only when the door mirror is at the return position, and the storage position detection switch 8 is configured to turn on only when the door mirror is at the storage position. . One end of each of the position detection switches 7 and 8 is connected to the ground terminal, and the other end is connected to the input terminal Q of the control circuit 3.
1, Q2 and their input terminals Q1, Q2
2 is connected to a plus potential control power supply terminal Vcc via pull-up resistors 7a and 8a, respectively.

As a result, when the return position detection switch 7 is off, that is, when the door mirror is at a position other than the return position, a high level signal (a signal corresponding to the potential to the control power supply terminal Vcc) is supplied to the input terminal Q1 of the control circuit 3. ) Is entered,
When the return position detection switch 7 is on, that is, when the door mirror is in the return position, the input terminal Q1 of the control circuit 3
, A low level signal (ground potential signal) is input. When the storage position detection switch 8 is off, that is, when the door mirror is at a position other than the storage position, a high-level signal is input to the input terminal Q2 of the control circuit 3,
When the storage position detection switch 7 is on, that is, when the door mirror is in the storage position, the input terminal Q2 of the control circuit 3
Is supplied with a low-level signal. Therefore, the position of the door mirror can be determined according to the input state to the input terminals Q1 and Q2 of the control circuit 3.

The control circuit 3 performs the following control in response to the turning on of the operation switch 9 of the automatic reset type.

That is, when the low level signal is given only to the input terminal Q1 when the operation switch 9 is turned on (when the door mirror is at the return position), the transistor 4 is turned on and the first relay 2 is turned on. Is operated to form a forward rotation energizing path of the motor 1, and the door mirror is rotated toward the storage position. Thereafter, when a low level signal is supplied to the input terminal Q2, that is, when the door mirror is turned to the retracted position, the transistor 4 is turned off to stop the operation of the first relay 2, and the motor 1 is turned off. .

When a low level signal is given only to the input terminal Q2 when the operation switch 9 is turned on (when the door mirror is at the storage position), the transistor 6 is turned on and the second relay 5 is operated. This forms a reverse rotation energizing path for the motor 1 and rotates the door mirror toward the return position. Thereafter, when the door mirror is rotated to the return position and a low level signal is given to the input terminal Q1, the transistor 6 is turned off, the operation of the second relay 5 is stopped, and the motor 1 is turned off.

When the operation switch 9 is turned on,
When the high level signal is given to both of the input terminals Q1 and Q2 (when the door mirror is at a position other than the return position and the storage position), the first relay 2 is operated to rotate the door mirror toward the storage position. At the same time, when a low level signal is supplied to the input terminal Q2, the motor 1 is turned off, so that a so-called storage priority operation is performed.

The control circuit 3 simultaneously controls the rotation of the passenger side door mirror. In this case, the rotation of the passenger side door mirror is synchronized with the rotation of the driver side door mirror. Control to be performed.

[0014]

[Problems to be Solved by the Invention] In the case of the above conventional configuration,
Since only a very small current of about 10 mA flows through the return position detection switch 7 and the storage position detection switch 8, an insulating oxide film grows on the surface of the contact portion, and the contact reliability often decreases. For this reason, various adverse effects appear on the rotation control of the door mirror, which causes a problem that the rotation control of the door mirror becomes uncertain.

That is, when a contact failure occurs in the return position detection switch 7, when the door mirror is rotated toward the return position in response to the turning on of the transistor 6, the door mirror is rotated to the return position. Since the low level signal is not supplied to the input terminal Q1 of the control circuit 3 at that time, the control circuit 3 does not turn off the transistor 6 no matter how long, and the power supply to the motor 1 is continued for a long time. Will be. Also, when a contact failure occurs in the storage position detection switch 8, when the door mirror is rotated toward the storage position, when the door mirror is rotated to the storage position, the input terminal Q2 of the control circuit 3 is low. Since the level signal is not supplied, the power supply to the motor 1 is continued for a long time.

In the conventional circuit shown in FIG. 4, the return position detection switch 7 is configured to be turned off only when the door mirror is at the return position, and the storage position detection switch 8 is provided.
Is turned off only when the door mirror is in the retracted position, when the position detection switches 7 and 8 have a poor contact, the input terminal Q1 of the control circuit 3
Alternatively, since the high level signal is kept applied to Q2, the door mirror is not rotated at all regardless of the operation of the operation switch 9.

The present invention has been made in view of the above circumstances, and its purpose is to improve the contact reliability of the return position detection switch and the storage position detection switch, and to ensure the rotation control of the door mirror. It is an object of the present invention to provide a control apparatus for an automobile door mirror which can be realized and has an effect that control for synchronizing the rotation of the left and right door mirrors can be reliably performed.

[0018]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a vehicle for reciprocatingly rotating a right side mirror and a left side mirror in a storage position and a return position in synchronization with each other. In the door mirror control device, an operation switch that outputs a rotation command signal in accordance with an external operation is provided, and the door mirror corresponding to one of the right and left door mirrors is rotated toward the storage position in the forward rotation direction in correspondence with one of the right and left door mirrors. A motor for rotating the door mirror in the return position direction when the door mirror is rotated and reversely rotated, a return position detection switch that is turned off when the corresponding door mirror is in the return position, and the corresponding door mirror is in the storage position A storage position detection switch that is turned off in a state, and forms a forward rotation energizing path of the motor in an operation state in which the excitation coil is energized. 1 relay, a second relay for forming a reverse rotation energizing path of the motor in an operating state in which the energizing coil is energized, and the energizing path of the exciting coil of the first relay when turned on is stored in the storage position. A first switching element formed via a detection switch, a second switching element forming an energizing path of an exciting coil of the second relay via the return position detection switch when turned on, and the motor A signal generating circuit for outputting an in-operation signal in each of the states where the forward rotation energizing path and the reverse rotation energizing path are formed, and the first and second signals when a rotation command signal is input.
An operation of giving an ON command to one of the switching elements and, when the operating signal is output in response to the ON command, continuing the output state of the ON command for the switching element until the output of the operating signal is stopped. Even if an ON command is given to one of the first and second switching elements, the ON signal is given to the other switching element when the ON signal is not output and the operating signal is output in response to the ON command. Operation to continue the output state of the ON command to the switching element until the output of the in-operation signal is stopped, and an operation start signal for synchronizing the other door mirror at the start and end of each operation. And a control circuit for outputting an operation end signal.

[0019]

For example, when the door mirror is at a position other than the storage position, the storage position detection switch is turned on.
In this state, when the rotation command signal is output in response to the operation of the operation switch, the control circuit receiving the rotation command signal outputs the first command.
For example, an ON command is given to one of the second switching elements, for example, the first switching element to turn it ON. At this time, since the storage position detection switch is on,
An energization path for the exciting coil of the first relay is formed, and a forward rotation energization path of the motor is formed according to the operation of the first relay. As a result, the motor starts to rotate forward and the door mirror starts rotating toward the storage position, and the operating signal is output from the signal generating circuit. Until the output is stopped, the output state of the ON command to the first switching element is continued, whereby the rotation of the door mirror is continued.

When the door mirror reaches the storage position by such rotation, the storage position detection switch is turned off. Then, the energizing path for the exciting coil of the first relay is cut off and the operation thereof is stopped, so that the forward rotation energizing path of the motor is cut off and the door mirror is stopped at the storage position. At the same time, the signal generation circuit stops outputting the in-operation signal, and the control circuit stops outputting the ON command to the first switching element. Further, the control circuit outputs an operation start signal and an operation end signal for synchronizing and rotating the other door mirror at the time of starting and ending the storage rotation of the door mirror.

On the other hand, when the door mirror is in the storage position (the storage position detection switch is turned off and the return position detection switch is turned on), a rotation command signal is output according to the operation of the operation switch. Also, when the control circuit receives the command, the control circuit gives an ON command to one of the first and second switching elements, for example, the first switching element to turn it ON. At this time, since the storage position detection switch is turned off, the excitation coil of the first relay is not energized despite the turning on of the first switching element.
There is no formation of a forward rotation path for the motor. Therefore, no signal during operation is output from the signal generation circuit.

When the operating signal is not output in spite of giving the ON command to the first switching element, the control circuit gives the ON command to the second switching element to turn it on. . Then, an energizing path for the exciting coil of the second relay is formed through the return position detection switch which is in the ON state at this time, and the reverse rotation of the motor is performed according to the operation of the second relay. An electrical path is formed. As a result, the motor is rotated in the reverse direction, the door mirror starts rotating toward the return position, and the in-operation signal is output from the signal generation circuit.
In the control circuit, the output state of the ON command to the second switching element continues until the output of the operation center signal is stopped, whereby the rotation of the door mirror is continued.

When the door mirror reaches the return position by such rotation, the return position detection switch is turned off. Then, the energizing path for the exciting coil of the second relay is cut off and its operation is stopped, so that the reverse rotation energizing path of the motor is cut off and the door mirror is stopped at the return position. At the same time, the signal generation circuit stops outputting the in-operation signal, and the control circuit stops outputting the ON command to the second switching element. Further, the control circuit outputs an operation start signal and an operation end signal for synchronously returning and rotating the other door mirror at the start and end of the return rotation of the door mirror.

In each of the above cases, the excitation coil current of the first or second relay, that is, a relatively large current flows through the return position detection switch and the storage position detection switch. Even if an insulating oxide film is formed on the substrate, the insulating film is blown off by the current, and there is no possibility that the contact reliability is reduced. As a result, the rotation control of the door mirror can be reliably performed, and the reliability of the operation start signal and the operation end signal for synchronously returning the other door mirror to return to rotation is increased, and the left and right door mirrors are controlled. Control for synchronizing the rotation can also be ensured. Also,
The first and second relays are operated only once each time when the door mirror is turned and retracted, so that there is no danger that the operation sound will be annoying and the life can be prolonged. .

1 to 3 show an embodiment of the present invention.
This will be described with reference to FIG.

In FIG. 1, a motor 12 provided on the driver's seat side door mirror unit 11 moves a driver's seat side door mirror (not shown) between a storage position parallel to the door and a return position projecting orthogonally from the door. It is provided for reciprocating rotation. Specifically, the motor 12 is rotated forward when the current flows in the direction of arrow A to rotate the door mirror in the storage position direction, and when the current flows in the direction opposite to arrow A, the motor 12 is rotated in the reverse direction to rotate the door mirror. Rotate in the return position direction. Actually, the door mirror is configured to be rotated to a front position further forward than the return position.

The return position detection switch 13 provided on the door mirror unit 11 is turned off when the door mirror is at the return position and at a position ahead of the return position, and is turned on when the door mirror is not at the above position. Present. Similarly, the storage position detection switch 14 provided on the door mirror unit 11 is turned off only when the door mirror is at the storage position, and turned on when the door mirror is not at the storage position. FIG. 2 shows the return position detection switch 13 and the storage position detection switch 1.
4 shows the on / off mode.

In the door mirror unit 11,
It has four terminals 11a to 11d, and both ends of the motor 12 are connected to the terminals 11a and 11d via the return position detection switch 13 and the storage position detection switch 14, respectively, and to the terminals 11b and 11c. Connected directly.

The first relay 15 has an exciting coil 15a and a transfer type relay switch 15b.
The relay 16 has an exciting coil 16a and a transfer type relay switch 16b. In this case, in the relay switches 15b and 16b, each normally open contact a is connected to the power terminal 17 having a positive potential, and each normally closed contact b is connected to the ground terminal. The common contact c of one relay switch 15b is connected to the terminal 11b of the door mirror unit 11, and the other relay switch 15b
6 is a terminal 11c of the door mirror unit 11.
Connected to.

The excitation coil 15a of the first relay 15 has one end connected to a power supply terminal 17 and the other end connected to a door mirror via an npn-type transistor 18 serving as a first switching element and a diode 19 having the illustrated polarity. Connected to terminal 11d of unit 11. The excitation coil 16a of the second relay 16 has one end connected to the power supply terminal 17 and the other end connected to the npn-type transistor 20 as the second switching element and the diode 2 having the polarity shown in the drawing.
1 is connected to a terminal 11 a of the door mirror unit 11. The bases of the transistors 18 and 20 are connected to output ports Q1 and Q2 of a control circuit 24 via base bias circuits 22 and 23, respectively.

The signal generating circuit 25 is configured by combining a diode OR circuit 26, an npn transistor 27 and resistors 28 to 31. Specifically, the anodes of the diodes 26a and 26b constituting the diode OR circuit 26 are connected to the terminals 11b of the door mirror unit 11, respectively.
11c, the cathodes of the diodes 26a and 26b are connected to the ground terminal via a series circuit of resistors 28 and 29, and the common connection point of the resistors 28 and 29 is connected to the base of the transistor 27. . Further, the collector of the transistor 27 is connected to a resistor 30 for pull-up.
Is connected to the control power supply terminal Vcc (for example, + 5V) via the input terminal D1 of the control circuit 24, and the emitter of the transistor 27 is connected to the ground terminal via the resistor 31.

The operation switch 32 is of an automatic reset type that is turned on only when operated externally, and is connected between the control power supply terminal Vcc and the input port D2 of the control circuit 24. As a result, an ON signal SON which rises every time the operation switch 32 is turned on is input to the input port D2 of the control circuit 24.

The control circuit 24 is constituted by a microcomputer. Hereinafter, the contents of control by the control circuit 24 and the operation related thereto will be described with reference to FIG.

That is, in FIG. 3, the control circuit 24 waits until the ON signal SON is input in response to the operation of the operation switch 32 (step A1). When the ON signal SON is input, the control circuit 24 turns off the output port Q1. The transistor 18 is turned on by inverting the output from a low level signal to a high level signal (step A2).

When the door mirror is at a position other than the storage position (including the return position) at the time of turning on, since the storage position detection switch 14 is in the ON state, the first relay 15 is excited. The current path for the coil 15a is determined by the contact (c−c) of the transistor 18, the diode 19, the storage position detection switch 14, and the relay switch 16b.
b) is formed via the first relay 1
No. 5 relay switch 15b is turned on between the contacts (ca).

As a result, a positive rotation path for the motor 12 is formed, and the door mirror starts rotating toward the storage position. Then, in the state where the normal rotation energizing path of the motor 12 is formed, the potential level of the terminal 11b rises to the potential level of the power terminal 17;
The transistor 27 in the signal generation circuit 25 is turned on through the diode OR circuit 26 or the like, and the in-operation signal Sd composed of a low level signal is output from the collector of the transistor 27 and applied to the input port D1 of the control circuit 24. Can be

When the door mirror is turned to the retracted position thereafter, the retracted position detecting switch 14 is turned off and the energizing path of the exciting coil 15a is cut off, so that the relay switch 15b is connected between the contacts (c-b). Return to ON state. Then, both ends of the motor 12 are connected to the relay switch 15.
Since the motor 12 is short-circuited by b and 16b, the motor 12 is braked, the door mirror is accurately stopped at the storage position, and the output of the in-operation signal Sd is stopped.

After the execution of step A2, the control circuit 24 determines the input state of the in-operation signal Sd to the input port D1 (step A3), and if the in-operation signal Sd has been input, That is, when the door mirror has started to rotate toward the storage position, the storage operation start signal Sks is output from the output port Q3 (step A4), and thereafter, the standby is continued until the input of the in-operation signal Sd is stopped. (Step A5).

When the input of the in-operation signal Sd is stopped ("YES" in step A5), that is, when the door mirror is turned to the retracted position, the control circuit 24 inverts the output of the output port Q1 to a low level signal. This causes the transistor 18 to be turned off (step A6), and thereafter outputs an operation end signal Se from the output port Q3 (step A7), and returns to step A1.

On the other hand, the control circuit 24 controls the transistor 1
If the door mirror is in the storage position at the time when the switch 8 is turned on (the time when step A2 is executed), the storage position detection switch 14 is turned off. 15 exciting coils 1
5a is not energized, and a forward rotation energizing path of the motor is not formed. Therefore, the in-operation signal Sd is not output from the transistor 27 in the signal generation circuit 25.

Accordingly, the control circuit 24 determines "NO" in step A3. In this case, the output of the output port Q1 is inverted to a low level signal, and
The output of the output port Q2 is inverted to a high level signal, thereby turning off the transistor 18 and turning on the transistor 20 (steps A8 and A9).

At this time, since the door mirror is in the retracted position and the return position detection switch 13 is in the ON state, the current path for the exciting coil 16a of the second relay 16 includes the transistor 20, the diode 21, the return position detection switch 13 , The contact (c-
b) is formed via the second relay 1
The relay switch 16b of No. 6 is turned on between the contacts (ca).

As a result, a reverse rotation path for the motor 12 is formed, so that the door mirror starts rotating toward the return position. In the state where the reverse rotation conduction path of the motor 12 is thus formed, the potential level of the terminal 11c rises to the potential level of the power supply terminal 17,
The transistor 27 in the signal generation circuit 25 is turned on through the diode OR circuit 26 or the like, and the in-operation signal Sd composed of a low level signal is output from the collector of the transistor 27 and applied to the input port D1 of the control circuit 24. Can be

When the door mirror is subsequently rotated to the return position, the return position detection switch 13 is turned off and the energizing path of the exciting coil 16a is cut off, so that the relay switch 16 is connected between the contacts (c-b). Return to ON state.
Then, both ends of the motor 12 are connected to the relay switches 15b, 1b.
6b, the motor 12
, The door mirror is accurately stopped at the return position, and the output of the in-operation signal Sd is stopped.

After the execution of step A2, the control circuit 24 determines the input state of the operating signal Sd to the input port D1 (step A10). If the operating signal Sd has been input, In other words, when the rotation of the door mirror in the direction of the return position has been started, a return operation start signal Sfs is output from the output port Q3 (step A11), and thereafter, the operation waits until the in-operation signal Sd is stopped. (Step A12).

When input of the in-operation signal Sd is stopped ("YES" in step A12), that is, when the door mirror is turned to the return position, the control circuit 24 inverts the output of the output port Q2 to a low level signal. Then, the transistor 20 is turned off (step A13). Thereafter, the step A7 for outputting the operation end signal Se from the output port Q3 is executed, and the process returns to the step A1.

Further, the control circuit 24 determines in step A1
0, that is, “NO”, that is, the transistor 1
If the turning operation of the door mirror is not performed at all despite the turning on of the switches 8 and 20, the error signal Sz is output from the output port Q4 (step A1).
4) When the error signal Sz is output, a failure display is performed by a not-shown notification means.

Although not shown, the passenger side door mirror unit which is paired with the driver side door mirror unit 11 is:
The storage operation start signal Sks, the return operation start signal Sfs, and the operation end signal Se output from the control circuit 24 as described above.
In each of the states in which the storage operation start signal Sks and the return operation start signal Sfs are received, a first mirror for rotating the door mirror in the storage position direction and the return position direction is provided.
Operating one of the relay and the second relay,
Each of the above relays is configured to stop operating when receiving the operation end signal Se. Thereby, the door mirror on the driver's seat side and the door mirror on the passenger's seat side are rotated synchronously.

In short, according to the configuration of the present embodiment, when the operation switch 32 is turned on in a state where the door mirror is at a position other than the storage position, the door mirror is automatically rotated to the storage position, and the door mirror is turned. When the operation switch 32 is turned on in the storage position, the door mirror is automatically rotated to the return position.

In this case, the return position detection switch 13 and the storage position detection switch 14, which determine the stop position at the time of automatic rotation of the door mirror as described above, include the exciting coil 15a of the first relay 15 or the second Since a load current flowing through the exciting coil 16a of the relay 16 of FIG. 2, that is, a relatively large current flows, even when an insulating oxide film is formed on the contacts of the position detection switches 13 and 14,
The insulating film is blown off by the current, and there is no possibility that the contact reliability is reduced. As a result, the rotation control of the door mirror can be reliably performed, and the storage operation start signal Sks and the return operation start signal Sk for synchronously returning and rotating the door mirror on the passenger seat side are provided.
The output reliability of the fs and the operation end signal Se is also increased, and the control for synchronizing the rotation of the left and right door mirrors can be ensured.

Further, the control circuit 24 operates the operation switch 32
Although the transistors 18 and 20 for operating the first and second relays 15 and 16 are sequentially turned on when the first relay is turned on, the first and second relays 15 and 16 are turned on. Is operated only once each time the door mirror is turned and retracted, so that the operation noise does not become annoying and the life can be extended.

In the above embodiment, the transistor 18 and the transistor 20 are turned on in this order in response to the on operation of the operation switch 32, so that the door mirror storage priority operation is performed. When the operation is performed, the transistor 20 is first turned on in response to the on operation of the operation switch 32, and then the transistor 1 is turned on.
8 may be turned on.
