  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(Embodiment 1)
<Control system>
FIG. 1 shows a control system S for a side mirror 10 (outer mirror) of an automobile according to the first embodiment.

  The control system S includes a pair of left and right side mirrors 10 and a side mirror control device 30 (outer mirror control device). When the shift lever is placed in the R range (predetermined mirror tilting operation), the rear wheel Control is performed to tilt the mirror surface of the side mirror 10 downward by a predetermined set tilt amount so that the periphery enters the driver's field of view.

  FIG. 2 shows the right side mirror 10.

  The side mirror 10 is attached to a position visible from the driver seat on the hinge side of the door so as to protrude sideways, and is provided so as to close the opening inside the bowl-shaped casing 11 opened rearward. The mirror body 12 is provided. In addition, a mirror body drive system 13 (tilt drive means) that is coupled to and supported by the mirror body 12 is provided inside the casing 11.

  The mirror main body drive system 13 includes a DC brush motor 20 and a vertical direction changing gear device that drives the mirror main body 12 so as to change the direction of the mirror surface in the vertical direction (tilting direction) by rotation thereof. .

  FIG. 3 shows the DC brush motor 20.

  The DC brush motor 20 is, for example, a three-slot type, and includes a rotating shaft 21 and a motor body 22 that accommodates and supports the rotating shaft 21.

  Each of the rotating shafts 21 is attached with three rotors 24 that are wound around a coil 23 and configured as an electromagnet via insulating portions. In addition, a commutator 25 for supplying power to the coil 23 coaxially with the rotor 24 is provided integrally with the rotor 24 on the rotary shaft 21.

  Inside the motor body 22, a stator 26 made of a pair of permanent magnets is fixed to the inner wall so as to sandwich the rotating shaft 21 from the side. A pair of brushes 27 are provided inside the motor body 22 so as to sandwich the commutator 25 of the rotating shaft 21. A motor drive wiring 28 is connected to each of the pair of brushes 27, and these are drawn out of the motor body 22.

  In this DC brush motor 20, when one of the motor drive wirings 28 is energized, the coil 27 supplies power to the coil 23 via the commutator 25, and each rotor 24 becomes an electromagnet, which repels the magnetic field of the stator 26. A force for rotating the rotary shaft 21 is expressed. When the rotating shaft 21 rotates together with the rotor 24 and the commutator 25, the direction of the current i fed from the brush 27 to the coil 23 via the commutator 25 is switched, so that the polarity of the electromagnet of each rotor 24 is successively changed. Inverted, each rotor 24 always repels the magnetic field of the stator 26 regardless of its rotational position and develops a force to rotate the rotating shaft 21. Thereby, the rotating shaft 21 rotates continuously in one direction (counterclockwise direction in FIG. 3). Further, when energization to the motor drive wiring 28 is reversed, that is, when one is energized from the other, the rotating shaft 21 rotates in the clockwise direction opposite to the above.

  The side mirror control device 30 includes a CPU 31 that is a central processing unit for controlling the side mirror, a driver circuit 32, a pair of brush noise detection circuits 33, a filter circuit 34, and a set tilt amount variable switch 35. The CPU 31 has an input system connected to the filter circuit 34 and the set tilt amount variable switch 35, and an output system connected to the driver circuit 32. The driver circuit 32 is connected to each of the pair of brush noise detection circuits 33. Each of the pair of brush noise detection circuits 33 is connected to the filter circuit 34.

  The CPU 31 includes an arithmetic processing unit 31a and an information storage unit 31b (RAM). The information storage unit 31b stores a first computer program that performs a control process for tilting the mirror body 12 of the side mirror 10 downward by a predetermined set tilt amount when the shift lever enters the R range.

  Further, the side mirror control device 30 includes a battery 40 as a power source, an external signal input wiring 50 through which an external signal based on various operations is transmitted, and a pair of motor driving wirings 28 extending from the DC brush motor 20. It is connected. The external signal input wiring 50 is connected to the input system of the CPU 31. One of the pair of motor driving wirings 28 is connected to one brush noise detection circuit 33 and the other is connected to the other brush noise detection circuit 33. Yes.

  In this side mirror control device 30, when an external signal for system on operation is input via the external signal input wiring 50, the CPU 31 enables the control system S while an external signal for system off operation is received. When input, switching control is performed to disable the operation.

  By the way, in the rotating operation of the DC brush motor 20, as the contact position between the commutator 25 and the brush 27 changes, brush noise corresponding to the contact between the insulating portion of the commutator 25 and each brush 27 is generated. The brush noise appears in the voltage (or current) at a constant cycle so as to correspond to the rotation angle of the DC brush motor 20. Specifically, as shown in FIG. 3, there are three insulating portions of the commutator 25, and the pair of brushes 27 are arranged with an interval of 180 °, so that as shown in FIG. Every time the rotation angle of the DC brush motor 20 changes by 60 °, one brush noise at the time of brush switching is generated in the voltage v. That is, six brush noises correspond to one rotation of the DC brush motor 20. Therefore, the rotation angle of the DC brush motor 20 can be converted from the number of brush noises, and the rotation angle of the DC brush motor 20 can be converted into the tilting amount of the mirror main body 12. Can be associated with the tilting amount of the mirror body 12.

  In the side mirror control device 30, the CPU 31 executes power supply control of the DC brush motor 20 via the motor drive wiring 28 by the driver circuit 32 in order to execute the first computer program and tilt the mirror body 12. At this time, the brush noise detection circuit 33 detects the brush noise and outputs it to the filter circuit 34. Further, the filter circuit 34 removes the low frequency component of the voltage waveform of the brush noise and outputs it to the CPU 31 as a signal waveform v ′ as shown in FIG. As described above, the number of brush noise pulses is associated with the amount of tilt of the mirror body 12. Therefore, in the power supply control of the DC brush motor 20 by the CPU 31, the number of brush noise pulses from the filter circuit 34 is determined by the CPU 31. Is measured based on the above.

  The set tilt amount variable switch 35 is composed of a rotary switch as shown in FIG. The set tilt amount variable switch 35 of the rotary switch changes the set tilt amount data, that is, the set pulse number data of the brush noise, to the CPU 31 and changes the set tilt amount within the continuous tilt amount range. However, by rotating the shaft in one direction (clockwise), changing the set pulse number data so that the amount of tilt can be increased, and rotating the shaft in the other direction (counterclockwise) The set pulse number data is varied so that the set tilt amount becomes small. Therefore, in the set tilt amount variable switch 35 of the rotary switch, the driver can check the set tilt amount by checking the rotational position of the shaft.

<Control method>
Next, the control method of the control system S of Embodiment 1 is demonstrated. Control of this control system S is based on execution of the 1st computer program memorize | stored in the information storage part 31b of CPU31.

  In this control system S, the driver rotates the axis of the set tilt amount variable switch 35 to change the set pulse number data of the brush noise in advance so that the desired set tilt amount is obtained, and the corresponding set pulse number data. Set to.

  When the shift lever is placed in the R range, first, an external signal that conveys the information is input to the CPU 31 via the external signal input wiring 50.

  In the CPU 31, the arithmetic processing unit 31 a reads the set pulse number data of the brush noise associated with the set tilt amount set by the set tilt amount variable switch 35, and the driver circuit 32 causes the DC via the motor drive wiring 28. Power is supplied to the brush motor 20 to tilt the mirror body 12 downward. At this time, the arithmetic processing unit 31a measures the number of pulses of the brush noise and compares it with the set number of pulses, while continuously supplying power when the measured number of pulses is less than the set number of pulses, When the measured number of pulses reaches the set number of pulses, power supply is stopped. As a result, the mirror main body 12 tilts downward by a predetermined set tilt amount and stops (for example, tilts 3 to 8 °), and the rear wheel periphery reliably enters the driver's field of view when the vehicle moves backward. . The set pulse number data is not changed even if the set tilt amount variable switch 35 is operated during the tilt operation of the mirror body 12. However, a configuration in which the tilt position of the mirror body 12 can be finely adjusted by operating the set tilt amount variable switch 35 after the tilt of the mirror body 12 is stopped may be employed.

  When the shift lever is changed from the R range to another after the vehicle has moved backward, an external signal for transmitting the information is input to the CPU 31 via the external signal input wiring 50, or the shift lever is set to the R range. The external signal that tells you that is in is released.

  In the CPU 31, the arithmetic processing unit 31 a supplies power to the DC brush motor 20 in reverse phase to the DC brush motor 20 via the motor driving wiring 28 by the driver circuit 32, and tilts the mirror body 12 upward. At this time, the arithmetic processing unit 31a resets the previously measured number of brush noise pulses, measures the number of pulses again, and compares it with the set number of pulses, and the measured number of pulses is less than the set number of pulses. In some cases, power supply is continued, while power supply is stopped when the measured number of pulses reaches the set number of pulses. Thereby, the mirror main body 12 returns to the original normal position. In addition, while counting down the number of pulses measured from the number of pulses of brush noise at the time of the previous power supply stop, if the remaining number is greater than zero, power is continuously supplied, while when the remaining number reaches zero You may make it stop electric power feeding.

  According to the side mirror control device 30 described above, since the set tilt amount variable switch 35 for changing the set tilt amount in the continuous tilt amount range is provided, a predetermined operation of the set tilt amount variable switch 35 is performed. Thus, the set tilt amount of the mirror main body 12 desired by the driver can be changed freely and easily.

(Embodiment 2)
<Control system>
A control system S for a side mirror 10 (outer mirror) of an automobile according to Embodiment 2 includes the same components as those of Embodiment 1 shown in FIG. Therefore, the following description will be made with reference to FIGS.

  In the control system S according to the second embodiment, in addition to the first computer program, the setting pulse of brush noise corresponding to the set tilt amount is set as the set tilt amount data associated with the set tilt amount in the information storage unit 31b. The second computer program for performing control processing for changing the setting of the numerical data and the set tilt amount data is stored.

  Further, the set tilt amount variable switch 35 is constituted by a rotary switch, but the other configurations including this are the same as those of the first embodiment.

<Control method>
-Basic control-
Next, basic control of the control system S of the second embodiment will be described. The basic control of the control system S is based on the execution of the first computer program stored in the information storage unit 31b of the CPU 31.

  In this control system S, when the shift lever is put in the R range, first, an external signal for transmitting the information is input to the CPU 31 via the external signal input wiring 50.

  In the CPU 31, the arithmetic processing unit 31a reads the set pulse number data of the brush noise associated with the set tilt amount stored in the information storage unit 31b, and the DC brush motor via the motor driving wiring 28 by the driver circuit 32. Power is supplied to 20, and the mirror body 12 is tilted downward. At this time, the arithmetic processing unit 31a measures the number of pulses of the brush noise and compares it with the set number of pulses, while continuously supplying power when the measured number of pulses is less than the set number of pulses, When the measured number of pulses reaches the set number of pulses, power supply is stopped. As a result, the mirror main body 12 tilts downward by a predetermined set tilt amount and stops (for example, tilts 3 to 8 °), and the rear wheel periphery enters the driver's field of view when the vehicle moves backward.

  When the shift lever is changed from the R range to another after the vehicle has moved backward, an external signal for transmitting the information is input to the CPU 31 via the external signal input wiring 50, or the shift lever is set to the R range. The external signal that tells you that is in is released.

  In the CPU 31, the arithmetic processing unit 31 a supplies power to the DC brush motor 20 in the opposite phase to the DC brush motor 20 via the motor drive wiring 28 by the driver circuit 32 and tilts the mirror body 12 upward. At this time, the arithmetic processing unit 31a resets the previously measured number of brush noise pulses, measures the number of pulses again, and compares it with the set number of pulses, and the measured number of pulses is less than the set number of pulses. In some cases, power supply is continued, while power supply is stopped when the measured number of pulses reaches the set number of pulses. In addition, while counting down the number of pulses measured from the number of pulses of brush noise at the time of the previous power supply stop, if the remaining number is greater than zero, power is continuously supplied, while when the remaining number reaches zero You may make it stop electric power feeding. Thereby, the mirror main body 12 returns to the original normal position.

−Setting change control of set tilt amount−
The setting change control of the set tilt amount of the control system S of the second embodiment will be described based on the flowchart of FIG. The setting change control of the set tilt amount of the control system S sequentially executes the procedure of the second computer program stored in the information storage unit 31b of the CPU 31.

  First, it waits until an external signal due to the entry operation in the tilt amount setting mode is input via the external signal input wiring 50, and the second computer program starts when an external signal is input through the entry operation in the tilt amount setting mode. Here, the tilt amount setting mode entry operation is not particularly limited. For example, as a first example, an operation of alternately repeating door lock and unlock within 5 seconds within 10 seconds after inserting a key, As a second example, an operation of turning off the system switch, turning on the accessory switch, and pressing each of the upper, lower, left, and right of a mirror position setting switch (not shown), etc. can be given. However, it is preferable that the tilt amount setting mode entry operation is not too simple from the viewpoint of safety and ease of setting operation, and on the other hand, is not complicated. If the mirror main body 12 is deviated from the normal position, that is, the set position during forward operation, the mirror main body 12 is operated by operating the mirror position setting switch before or after performing the tilt amount setting mode entry operation. Adjust the position to the normal position.

  In step S1 after the start, the processing mode enters the tilt amount setting mode, and proceeds to the subsequent step S2.

  In step S2, it waits until the signal by tilt amount data variable start operation is input. Here, the tilt amount data variable start operation is not particularly limited. For example, when the tilt amount setting mode entry operation is the above first example, the operation of putting the shift lever into the R range, the second example In this case, an operation for turning on the system switch, and the like can be given. In the case of the first example, generally, the shift lever can be moved by inserting a key and stepping on the foot brake. Therefore, the shift lever can be put in the R range without starting the engine, and therefore the vehicle starts to move. There is no danger. Further, the tilt amount data variable start operation may be a predetermined operation of the set tilt amount variable switch 35.

  When an external signal from the tilt amount data variable start operation is input, the process proceeds to step S3, and the tilt amount data associated with the tilt amount, that is, the pulse number data of the brush noise corresponding to the tilt amount can be continuously varied. The process proceeds to step S4.

  At this time, when the driver rotates the axis of the set tilt amount variable switch 35, a signal is inputted so as to continuously change the set pulse number data of the brush noise in accordance with the rotation amount, and the driver circuit 32 correspondingly corresponds thereto. Thus, power is supplied to the DC brush motor 20 via the motor drive wiring 28, and the mirror body 12 is tilted up and down or stopped.

  As described above, since the mirror body 12 tilts in response to continuously changing the pulse number data of the brush noise, the driver can adjust the tilt amount while actually checking the mirror body 12. it can.

  Further, since the mirror body 12 can be not only tilted downward (one side in the tilting direction) but also stopped or tilted upward (the other side in the tilting direction), the desired tilting position is excessive. However, the mirror body 12 can be stopped or returned immediately, and the tilt amount of the mirror body 12 can be easily adjusted.

  In step S4, it waits until the signal by setting value determination operation is input. That is, this is a process executed by performing a setting value determining operation when the driver reaches the desired tilting position while checking the mirror body 12 that tilts. At this time, the pulse number data of the brush noise corresponding to the tilt amount from the normal position of the mirror body 12 to the desired tilt position is determined as the set value. Here, the setting value determining operation is not particularly limited. In the case of the first example, the operation of changing the shift lever to other than the R range, and in the case of the second example, the system switch is turned off. And the like. Further, the set value determining operation may be a predetermined operation of the set tilt amount variable switch 35.

  When the set value determination operation signal is input, the process proceeds to step S5, where the brush noise set pulse number data stored in the information storage unit 31b of the CPU 31 is rewritten with the determined brush noise pulse number data, and the following step S6 is performed. Proceed to

  In step S6, the DC power is supplied to the DC brush motor 20 by the driver circuit 32 to return the mirror main body 12 to the normal position, the tilt amount setting mode is canceled, and the process ends. Here, even if the configuration is such that this processing is executed when an external signal is input by a predetermined operation, step S5 is performed simultaneously when an external signal is input by the set value determination operation in step S4. And the structure which progresses to step S6 may be sufficient. In addition, for example, when the door is opened, when the ignition switch is turned on, or when more than 30 seconds have passed after entering the tilt amount setting mode, all of them are canceled to cancel the tilt amount setting mode. The structure which complete | finishes may be sufficient.

  According to the side mirror control device 30 described above, since the set tilt amount variable switch 35 for changing the set tilt amount in the continuous tilt amount range is provided, the predetermined tilt amount variable switch 35 is set in the tilt amount setting mode. By performing the above operations, the setting tilt amount of the mirror main body 12 desired by the driver himself can be freely and easily changed.

(Embodiment 3)
<Control system>
The control system S of the side mirror 10 (outer mirror) for an automobile according to the third embodiment includes the same components as those of the first embodiment shown in FIG. Therefore, the following description will be made with reference to FIGS.

  In the control system S according to the third embodiment, in addition to the first computer program, the setting pulse of brush noise corresponding to the set tilt amount is set as the set tilt amount data associated with the set tilt amount in the information storage unit 31b. Numeric data is stored.

  The set tilt amount variable switch 35 is configured by a push switch as shown in FIG. The set tilt amount variable switch 35 of the push switch can change the set tilt amount data, that is, the set pulse number data of the brush noise, to the CPU 31 and change the set tilt amount within the continuous tilt amount range. However, as a specific configuration, the set tilt amount data is changed so that the set tilt amount increases while the button is pressed, then stops while the switch is released, and then the button is pressed. The set tilt amount data is changed so that the set tilt amount is reduced while the switch is being moved, and then the operation of stopping while the switch is released is cyclically repeated. When the set tilt amount reaches the maximum value, it is reset and the set tilt amount data is changed cyclically.

  The set tilt amount variable switch 35 includes a first push switch that changes the set tilt amount data so that the set tilt amount increases, and a second push switch that changes the set tilt amount data so that the set tilt amount decreases. The structure provided with these two push switches may be sufficient. In this case, the first push switch has a configuration in which the set tilt amount data is changed so that the set tilt amount increases while the button is pressed, and the stop operation is cyclically repeated while the switch is released. Even when the setting tilt amount is increased by 1 °, for example, each time it is pressed, the tilt amount data may be cyclically reset to change the set tilt amount data when the set tilt amount reaches the maximum value. Similarly, the second push switch has a configuration in which the set tilt amount data is changed so that the set tilt amount decreases while the button is pressed, and the operation of stopping while the switch is released is cyclically repeated. Even when there is a configuration, the set tilt amount may be reduced by, for example, 1 ° each time the button is pressed, and when the set tilt amount reaches the minimum value, the set tilt amount data may be changed cyclically.

  Even if the constant set tilt amount is varied each time the button is pressed, if the constant set tilt amount is about 1 ° or less, for example, the set tilt amount is substantially within the continuous tilt amount range. Can be said to be a variable.

  Other configurations are the same as those of the first embodiment.

<Control method>

  In this control system S, when the shift lever is put in the R range, first, an external signal for transmitting the information is input to the CPU 31 via the external signal input wiring 50.

  In the CPU 31, the arithmetic processing unit 31a reads the set pulse number data of the brush noise associated with the set tilt amount stored in the information storage unit 31b, and the DC brush motor via the motor driving wiring 28 by the driver circuit 32. Power is supplied to 20, and the mirror body 12 is tilted downward. At this time, the arithmetic processing unit 31a measures the number of pulses of the brush noise and compares it with the set number of pulses, while continuously supplying power when the measured number of pulses is less than the set number of pulses, When the measured number of pulses reaches the set number of pulses, power supply is stopped.

  After the mirror body 12 stops tilting, when the driver pushes the set tilt amount variable switch 35 of the push switch in a predetermined manner, the set pulse number data of the brush noise is continuously changed according to the operation. Accordingly, the arithmetic processing unit 31a supplies power to the DC brush motor 20 via the motor driving wiring 28 by the driver circuit 32 correspondingly, and the tilt position of the mirror body 12 is finely adjusted. As a result, the mirror body 12 tilts downward by a predetermined set tilt amount and stops (for example, tilts 3 to 8 °), and is finely adjusted to the tilt position desired by the driver (for example, 3 to 8 °). Fine adjustment within the range of.

  When the shift lever is changed from the R range to another after the vehicle has moved backward, an external signal for transmitting the information is input to the CPU 31 via the external signal input wiring 50, or the shift lever is set to the R range. The external signal that tells you that is in is released.

  In the CPU 31, the arithmetic processing unit 31 a supplies power to the DC brush motor 20 in the opposite phase to the DC brush motor 20 via the motor drive wiring 28 by the driver circuit 32 and tilts the mirror body 12 upward. At this time, the arithmetic processing unit 31a resets the previously measured number of brush noise pulses, measures the number of pulses again, and compares it with the set number of pulses, and the measured number of pulses is less than the set number of pulses. In some cases, power supply is continued, while power supply is stopped when the measured number of pulses reaches the set number of pulses. Thereby, the mirror main body 12 returns to the original normal position. In addition, while counting down the number of pulses measured from the number of pulses of brush noise at the time of the previous power supply stop, if the remaining number is greater than zero, power is continuously supplied, while when the remaining number reaches zero You may make it stop electric power feeding.

  According to the side mirror control device 30 described above, since the set tilt amount variable switch 35 for changing the set tilt amount in the continuous tilt amount range is provided, a predetermined operation of the set tilt amount variable switch 35 is performed. Thus, the set tilt amount of the mirror main body 12 desired by the driver can be changed freely and easily.
