[0002]

2. Description of the Related Art In a conventional electric retractable mirror, a mirror arm position detecting switch is not provided in a mirror arm mechanism portion, and when one of a seesaw type mirror arm operation switch near a driver is pressed, power is supplied in a certain direction for a predetermined time. Then, the mirror arm protrudes outside the vehicle, the arm stops at a specific position, and when the opposite side of the switch is pressed, electricity is supplied for a certain period in the opposite direction, and the arm returns to its original state. is there. Further, the input to the mirror arm operation switch has only a function as a trigger regardless of the energization time.

In view of the above, a special specification is provided for the above-mentioned standard specification, and a mechanism for stopping the mirror arm when it is desired to stop the arm in the middle is provided.

In this mechanism, the mirror arm operation switch provided by the driver is energized only for the time the switch is pressed, and when the electric mirror arm reaches a specific position, the mirror position is reported to the mirror arm drive control unit. A mirror arm position detection switch is built in. When the mirror arm is not located at the specific position (OFF), the power is kept on. When the switch arrives at the specific position (ON), the mirror arm is operated once regardless of the operation of the mirror arm operation switch on the driver side. Is stopped.

[0005]

However, when both the standard specification and the special specification are provided, a control unit is required. However, conventionally, only the operation switch is a common part, and therefore, the number of parts is increased. , And misassembly occurred.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a control method and a control apparatus for a mirror arm of an automobile, in which the number of parts is small and erroneous assembly does not occur, by sharing parts.

SUMMARY OF THE INVENTION A method of controlling a mirror arm of an electric retractable mirror according to the present invention includes a vehicle specification storing step, an operation switch input step, a power supply step to a driving motor, The process consists of a process for checking the elapse of a certain period of power supply to the motor, a process for detecting the mirror position, and a process for stopping the supply of power to the drive motor. Power is supplied to the mirror arm drive motor while the mirror arm operation switch is input, but the power supply is stopped by stopping the input of the operation switch and the position provided on the mirror arm. It is possible to respond to the special specification that stops even by input from the detection switch, and in the power supply process to the drive motor, To operate as a standard specification when you supply.

When the position of the mirror arm is detected in the mirror position detecting step during the operation of the mirror arm, the mirror arm operates as a special specification from that point on, and is stored as the special specification in the vehicle specification storing step. Continue operation.

In the step of supplying power to the drive motor, the power supply is stopped, and when the power is turned on again, the operation returns to the standard specification.

The mirror arm control device of the electric retractable mirror according to the present invention includes a mirror arm operation switch, a mirror arm driving mechanism comprising a mirror arm driving motor and a mirror arm position detection switch, and a mirror arm. And a control unit for controlling the driving of the mirror arm. A standard specification for supplying power to the mirror arm driving motor for a certain period of time by inputting the mirror arm operation switch, and a mirror arm driving motor while the mirror arm operation switch is being input. The power supply can be stopped, but in addition to stopping the input of the operation switch, it can also respond to the special specification of stopping by the input from the position detection switch provided on the mirror arm. When the mirror arm is in operation, it operates as a standard specification. Pitch the position is changed, and operates as a special specification from that point when grounded, is stored as a special specification vehicle specification storing function of the control unit,
Continue the operation as a special specification.

When the power supply is stopped and the power is turned on again, the operation returns to the standard operation.

FIG. 1 is a system configuration diagram showing the entire control device of the electric retractable mirror, and FIG. 2 is a flowchart showing a control method of the electric retractable mirror. FIG. 3 is a system configuration diagram according to another embodiment.

First, the configuration will be described with reference to FIG.

In FIG. 1, a control unit 1 having a vehicle specification storage device is connected to a power supply 3 by a power supply circuit 2, to an ignition 6 by an operation circuit 5 via a mirror arm operation switch 4 on the driver side, and to a drive circuit. 7 is connected to a drive motor 9 built in a mirror arm drive mechanism 8 having a mirror and a mirror arm, and further via a ground circuit 10 and a mirror arm position detection switch 11 built in the mirror arm drive mechanism 8. Grounded (earthed).

Next, a method of controlling the mirror arm of the electric retractable mirror will be described with reference to FIG. 2 and also to FIG. First, the process is started, and the vehicle specifications are set to standard specifications as vehicle specifications by the vehicle specification storage device 12 shown in FIG. 1 (step S1, described as S1 in the figure, and so forth). Next, FIG.
The control unit 1 determines whether or not the mirror arm operation switch 4 shown in (1) is in an input state (step S2), and if not (NO in step S2), step S2 is performed.
Repeat 2.

In the input state (YE in step S2)
In the case of S), the power is supplied from the power supply 3 to the drive motor 9 (step S3), and then the control unit 1 determines from the vehicle specification storage device 12 whether the vehicle specification is the standard specification or the special specification. (Step S4) If the standard specification (standard in step S4), the next step S
Then, if it is a special specification (special in step S4), the flow proceeds to step S8.

In step S5, it is determined by the timer function of the control unit 1 whether or not a fixed time has elapsed in the standard specification state. If the fixed time has not elapsed (NO in step S5), the flow proceeds to step S6, and the fixed time has elapsed. If the time has elapsed (YES in step S5), the process proceeds to step S10.

In step S6, it is determined whether the position detection switch 11 is OFF (OPEN) or ON (CLOSE (earth)). If OFF (OPEN in step S6), the process returns to step S5, and ON.
If (CLOSE in step S6), the vehicle specification memory is set to the special specification (step S7), and the process proceeds to the next step S8.

In step S8 (control is performed as a special specification in steps after step S8), the control unit 1 determines whether or not the mirror arm operation switch 4 is in an input state, and the input is not input (NO in step S8).
In this case, the control proceeds to step S10, and in the input state (YES in step S8), the flow proceeds to the next step S9.

In step S9, it is determined whether the position detection switch 11 is OFF (OPEN) or ON (CLOSE (earth)). If OFF (OPEN in step S9), the process returns to step S8 and ON.
If (CLOSE in step S9), the power supply to the drive motor 9 is stopped and the mirror arm is also stopped (step S10). Next, it is determined whether or not the mirror arm operation switch 4 is in the input state. In the input state (for example, when the driver keeps pressing the switch 4 even when the drive motor 9 is stopped,
In the case of (S), step S11 is repeated, and if not in the input state (NO in step S11), the control returns to step S2.

FIG. 3 shows another embodiment, in which a control mode input terminal is provided in FIG. 1 and grounded.
