Description

  The present invention relates to a vehicle mirror device in which a tilt mechanism tilts a mirror provided in a vehicle.

  In the electric mirror device for a vehicle described in Patent Document 1 below, when the shift lever is moved to the shift position corresponding to the reverse range, the motor rotates the mirror from the return position to the rear wheel visual recognition position. Thereafter, when the shift lever is released from the shift position corresponding to the reverse range, the motor rotates the mirror from the rear wheel viewing position to the return position.

  Here, in the electric mirror device for a vehicle, when the mirror is rotated from the rear wheel viewing position toward the return position, the actual position where the mirror is actually rotated is outside a predetermined range including the return position. In this case, the motor rotates the mirror from the actual position to the return position. However, if the actual position of the mirror is within the predetermined range, the motor does not rotate the mirror from the actual position to the return position. Thereby, it is suppressed that a passenger | crew feels troublesome.

  A substantially hemispherical container-like case 22 is provided at the front side portion of the mirror surface adjustment unit 20, and the inside of the case 22 is opened to the rear side of the vehicle. The case 22 is supported by the visor 12, whereby the mirror surface adjustment unit 20 is supported by the visor 12.

  A tilting body 24 (mirror holder inner) is provided on the rear side portion of the mirror surface adjustment unit 20, and the tilting body 24 is held by the case 22 so as to be tiltable (swinging and rotating). The tilting body 24 is provided with a substantially cylindrical slide cylinder 24A. The diameter of the slide cylinder 24A is gradually reduced toward the front side of the vehicle so as to be slidable with respect to the peripheral wall of the case 22. ing. A substantially disc-shaped mounting plate 24B is integrally provided at the vehicle rear side end of the sliding cylinder 24A, and the mirror holder 18 of the mirror 14 is detachably mounted on the vehicle rear side of the mounting plate 24B. Yes. Thereby, the mirror 14 can be tilted with respect to the case 22 integrally with the tilting body 24 around the center of gravity position (the surface center position of the mirror surface 16A).

  A vertical motor 26 and an internal / external motor (not shown) as tilting means (motors) are fixed in the case 22, and the vertical motor 26 and the internal and external motors have rod-like vertical and vertical movement members (adjustment rods), respectively. The rod 28 and the inner and outer rods (not shown) are connected via a gear mechanism (not shown). The upper and lower rods 28 and the inner and outer rods are held in the case 22 so as to be slidable (movable) in the longitudinal direction (axial direction) of the vehicle. The tip of the inner and outer rods (the rear side end of the vehicle) is located outside the vehicle 14 in the vehicle width direction (inside the vehicle width direction) of the center of gravity position of the mirror 14. In this case, the mounting plate 24B is rotatably held.

  The vertical motor 26 and the internal and external motors are electrically connected to an ECU 30 (mirror ECU) as a control means in the visor 12 or on the vehicle body side, and an adjustment operating device 32 as an operation means for the vehicle is electrically connected to the ECU 30. It is connected to the. When the adjustment operation device 32 is operated by a vehicle occupant (especially a driver), the mirror surface adjustment unit 20 is operated under the control of the ECU 30, and the vertical motor 26 and the internal / external motor are driven, whereby the vertical rod 28 and the inner and outer rods are slid in the vehicle longitudinal direction, and the tilting body 24 and the mirror 14 are tilted with respect to the case 22. Thereby, the tilt position of the mirror 14 is adjusted, and the mirror surface 16A angle (the direction in which the mirror surface 16A is directed) of the mirror 14 is adjusted.

  When the upper and lower rods 28 are slid forward, the tilting body 24 and the mirror 14 are tilted upward (upward direction), and the mirror surface 16A of the mirror 14 is tilted upward. When the upper and lower rods 28 are slid rearward, the tilting body 24 and the mirror 14 are tilted downward (downward direction), and the mirror surface 16A of the mirror 14 is tilted downward. When the inner and outer rods are slid forward, the tilting body 24 and the mirror 14 are tilted outward (outward direction), and the mirror surface 16A of the mirror 14 is tilted outward in the vehicle width direction. When the inner and outer rods are slid rearward, the tilting body 24 and the mirror 14 are tilted inward (inward direction), and the mirror surface 16A of the mirror 14 is tilted inward in the vehicle width direction.

  As shown in FIG. 3, when the tilt position of the mirror 14 in the inner and outer directions (one direction) is X and the tilt position of the mirror 14 in the vertical direction (the other direction) is Y, the tiltable range of the mirror 14 is tilted. It is limited within the possible area Q.

  As shown in FIG. 2, the case 22 is provided with a vertical sensor 34 and an internal / external sensor (not shown) as detection means (sensor), and the vertical sensor 34 and the internal / external sensor are electrically connected to the ECU 30, respectively. ing. Each of the vertical sensor 34 and the internal / external sensor is provided with a substantially rectangular box-shaped housing 36, and the vertical sensor 34 and the internal / external sensor are attached to the case 22 by fixing the housing 36 to the outside of the bottom wall of the case 22. It is fixed.

  A rod-shaped detection rod 38 as a detection member is provided in the housing 36 so as to be slidable in the vehicle front-rear direction (axial direction). The detection rod 38 protrudes from the housing 36 toward the rear of the vehicle and It is urged to the side. The detection rod 38 passes through the bottom wall of the case 22 and is inserted into the case 22. The vertical sensor 34 and the internal / external sensor detection rods 38 are coaxially arranged on the vehicle front side of the vertical rod 28 and the internal / external rod, respectively. Has been placed. The leading ends (vehicle rear side ends) of the vertical sensor 34 and the inner and outer sensor detection rods 38 are in contact with the vertical rods 28 and the base ends (front end of the vehicle) of the inner and outer rods by a biasing force, respectively. The detection rod 38 is always slidable in the vehicle front-rear direction integrally with the upper and lower rods 28 and the inner and outer rods. Therefore, the vertical sensor 34 and the internal / external sensor detect the sliding position of the detection rod 38 in the vehicle longitudinal direction, respectively, so that the vertical sensor 34 and the internal / external sensor respectively detect the vertical rod 28 and the internal / external rod in the vehicle longitudinal direction. The slide position is detected, and the tilt position of the mirror 14 in the vertical direction and inward / outward direction is detected.

  A vehicle automatic transmission 40 (transmission) is electrically connected to the ECU 30, and a shift lever device 42 as a vehicle operating device is mechanically or electrically connected to the automatic transmission 40. Yes. When the shift lever device 42 is operated by a vehicle occupant (driver), the shift range (shift position) of the automatic transmission 40 is, for example, “P” range (parking range), “R” range (reverse range). , “N” range (neutral range), “D” range (drive range), etc.

  Next, the operation of the present embodiment will be described.

  In the vehicle door mirror device 10 having the above-described configuration, when the adjustment operation device 32 is operated, the mirror surface adjustment unit 20 is operated under the control of the ECU 30, and the vertical motor 26 and the inner and outer motors are driven. The rod 28 and the inner and outer rods are slid in the vehicle longitudinal direction. For this reason, the tilting body 24 and the mirror 14 are tilted in the vertical direction and inward / outward direction with respect to the case 22, so that the tilting position (mirror surface 16 </ b> A angle) of the mirror 14 is adjusted. The viewing range is adjusted.

  When the vertical rod 28 and the inner and outer rods are slid in the vehicle longitudinal direction, the detection rod 38 is slid in the vehicle longitudinal direction together with the vertical rod 28 and the inner and outer rods in the vertical sensor 34 and the inner and outer sensors, respectively. Thereby, when the tilt position of the mirror 14 is adjusted, the tilt positions of the mirror 14 in the vertical direction and the internal / external direction are detected by the vertical sensor 34 and the internal / external sensor, respectively.

  Further, the mirror surface adjustment unit 20 may be automatically operated (AUTO) under the control of the ECU 30.

  For example, when the shift lever device 42 is operated and the shift range of the automatic transmission 40 is changed to the “R” range, the mirror surface adjustment unit 20 is operated under the control of the ECU 30, and the vertical motor 26 and the inner and outer motors 26 By driving at least one of the motors, the mirror 14 is tilted in at least one of the vertical direction and the inner and outer directions, and the mirror 14 is automatically tilted from the normal position to the reverse position. Thereby, the mirror surface 16A of the mirror 14 is directed obliquely downward to the rear of the vehicle, and the occupant (driver) can visually recognize the rear wheel of the vehicle and its surroundings by the mirror 14.

  Thereafter, when the shift lever device 42 is operated and the shift range of the automatic transmission 40 is changed to a range other than the “R” range (for example, the “P” range), the mirror surface adjustment unit 20 is operated under the control of the ECU 30. Then, by driving at least one of the vertical motor 26 and the internal / external motor, the mirror 14 is tilted in at least one of the vertical direction and the internal / external direction, and the mirror 14 is automatically tilted from the reverse position to the normal position.

  By the way, as shown in FIG. 3, the mirror surface adjustment unit 20 is automatically operated by the control of the ECU 30, and the mirror 14 is, for example, the current position (Xg, Yg) which is the reverse position as the initial position, for example, the target position which is the normal position. When it is automatically tilted toward (Xc, Yc), the stop position as the actual position where the mirror 14 is actually tilted may cause an error (deviation) with respect to the target position (Xc, Yc). .

  The ECU 30 determines an error with respect to the target position (Xc, Yc) of the stop position of the mirror 14 when the mirror 14 is tilted from the current position (Xg, Yg) toward the target position (Xc, Yc). Based on the tilt position of the mirror 14 in the vertical direction and the internal / external direction detected by the internal / external sensor, the correction value (correction value) is stored (learned).

  In general, the error of the stop position of the mirror 14 with respect to the target position (Xc, Yc) varies for each positional relationship between the current position (Xg, Yg) of the mirror 14 and the target position (Xc, Yc). For example, the error of the stop position of the mirror 14 with respect to the target position (Xc, Yc) increases as the tilting amount of the mirror 14 from the current position (Xg, Yg) to the target position (Xc, Yc) increases. Of the mirror 14 increases as the distance from the center position (Xo, Yo) of the tiltable region Q of the mirror 14 increases.

  For this reason, the ECU 30 divides the tiltable region Q of the mirror 14 into a plurality of areas (in the present embodiment, nine areas A to I), and the ECU 30 determines the current position (Xg, Yg) for each combination of the area (eg, area G) and the target position (Xc, Yc) (eg, area C), the error relative to the target position (Xc, Yc) of the stop position of the mirror 14 is corrected by a correction value (Xh). , Yh) (see FIG. 5). For example, when the stop position is (Xc + 3, Yc-1), the correction value (Xh, Yh) is set to (+3, -1). Further, when the stop position is (Xc ± 0, Yc ± 0), the correction value (Xh, Yh) is set to (0, 0).

  A = (Xg−Xo) 2+ (Yc−Yo) 2 and B = (Xc−Xo) 2+ (Yg−Yo) 2. In the case of A ≧ B (A> B may be used), when the mirror 14 is tilted from the current position (Xg, Yg) toward the target position (Xc, Yc), the vertical motor 26 is driven and the mirror 14 is driven. After 14 is tilted in the vertical direction, the inner and outer motors are driven to tilt the mirror 14 in the inner and outer directions. In the case of A <B (A ≦ B may be satisfied), when the mirror 14 is tilted from the current position (Xg, Yg) toward the target position (Xc, Yc), the inner and outer motors are driven and the mirror 14 is driven. Is tilted inward and outward, the vertical motor 26 is driven to tilt the mirror 14 in the vertical direction. Thereby, even when the outer peripheral line of the tiltable region Q of the mirror 14 is not parallel to the X axis and the Y axis, the mirror 14 can tilt within the tiltable region Q, and the mirror 14 needs to tilt outside the tiltable region Q. The mirror 14 can tilt from the current position (Xg, Yg) to the target position (Xc, Yc).

  Further, when the mirror 14 is tilted in the order from the up-down direction to the inside-out direction, the tilt position of the mirror 14 in the up-down direction is likely to cause an error when the mirror 14 is tilted in the inside-out direction. When the mirror 14 is tilted in the vertical direction from the inner and outer directions, the tilt position of the mirror 14 in the inner and outer directions is likely to cause an error when the mirror 14 is tilted in the vertical direction.

  For this reason, the ECU 30 stores, as a correction value (Xh, Yh), an error with respect to the target position (Xc, Yc) of the stop position of the mirror 14 in each order of the vertical direction and the inside / outside direction in which the mirror 14 is tilted ( (See FIG. 5).

  As shown in FIG. 4, when the mirror surface adjustment unit 20 is automatically operated under the control of the ECU 30 and the mirror 14 is automatically tilted from the current position (Xg, Yg) to the target position (Xc, Yc), First, in step 100, whether or not a condition for automatically operating the mirror surface adjustment unit 20 is satisfied (for example, whether or not the shift range of the automatic transmission 40 has been changed from the “R” range to other than the “R” range). Is determined.

  If it is determined in step 100 that the condition for automatically operating the mirror surface adjustment unit 20 is not satisfied, the process of step 100 is performed again.

  When it is determined in step 100 that the conditions for automatically operating the mirror surface adjustment unit 20 are satisfied, in step 102, the current position (Xg, Yg) and target position (Xc, Yc) of the mirror 14 are determined. And an area (for example, area G) of the current position (Xg, Yg) and an area (for example, area C) of the target position (Xc, Yc) are determined.

  Next, in step 104, the magnitudes of A (= (Xg-Xo) 2+ (Yc-Yo) 2) and B (= (Xc-Xo) 2+ (Yg-Yo) 2) are compared.

  If it is determined in step 104 that A ≧ B (A> B may be satisfied), in step 106, the target position (Xc, Yc) is corrected as the corrected target position based on the deviation correction value table in FIG. Correction is made to the target position Ch (Xc-Xh, Yc-Yh). For example, when the correction value (Xh, Yh) is (+3, −1), the correction target position Ch (Xc−Xh, Yc−Yh) is set to (Xc−3, Yc + 1).

  If it is determined in step 104 that A <B (A ≦ B may be satisfied), in step 108, the target position (Xc, Yc) is changed to the corrected target position Ch (Xc) based on the deviation correction value table in FIG. -Xh, Yc-Yh). For example, when the correction value (Xh, Yh) is (0, 0), the correction target position Ch (Xc-Xh, Yc-Yh) is set to (Xc, Yc).

  After step 106 or step 108, in step 110, the mirror surface adjustment unit 20 is automatically operated, and the mirror 14 moves from the current position (Xg, Yg) to the corrected target position Ch (Xc-Xh, Yc-Yh). It is tilted automatically toward. In step 110, when it is determined in step 104 that A ≧ B (A> B may be satisfied), the mirror 14 is tilted in the order from the vertical direction to the inside / outside direction, and in step 104, A <B (A ≦ B The mirror 14 is tilted in the order from the inner and outer directions to the vertical direction.

  Next, in step 112, it is determined whether or not the stop position where the mirror 14 is actually tilted (stopped) is the target position (Xc, Yc).

  In step 112, if the stop position of the mirror 14 is not the target position (Xc, Yc), in step 114, an error with respect to the target position (Xc, Yc) of the stop position of the mirror 14 is stored and based on the error. Update the correction value. For example, when the correction value (Xh, Yh) before the update is (+3, −1) and the stop position is (Xc−1, Yc + 2), the correction value (Xh, Yh) is It is updated to (+ 3-1, -1 + 2) = (+ 2, +1).

  Thereafter, in step 116, the mirror surface adjustment unit 20 is automatically activated again, and the mirror 14 is automatically tilted from the stop position to the target position (Xc, Yc). The automatic operation process is terminated, and the process returns to step 100.

  If the stop position of the mirror 14 is the target position (Xc, Yc) in step 112, the automatic operation process of the mirror surface adjustment unit 20 is ended in step 118, and the process returns to step 100.

  Here, as described above, in the ECU 30, when the mirror 14 is automatically tilted from the current position (Xg, Yg) toward the target position (Xc, Yc), the stop position of the mirror 14 is changed to the target position (Xc , Yc), an error is stored as a correction value (Xh, Yh), and the mirror 14 is tilted from the stop position to the target position (Xc, Yc).

  Thereafter, when the mirror 14 is automatically tilted from the current position (Xg, Yg) toward the target position (Xc, Yc), the mirror 14 moves to the corrected target position Ch (Xc-Xh, Yc-Yh). It is tilted automatically toward. For this reason, it can suppress that the stop position of the mirror 14 generates an error with respect to the target position (Xc, Yc), and suppresses the mirror 14 from being automatically tilted again from the stop position to the target position (Xc, Yc). It can suppress that a passenger | crew feels troublesome.

  Further, for each combination of the area of the current position (Xg, Yg) of the mirror 14 and the area of the target position (Xc, Yc), the error with respect to the target position (Xc, Yc) of the stop position of the mirror 14 is corrected by a correction value (Xh). , Yh). For this reason, the error of the stop position of the mirror 14 with respect to the target position (Xc, Yc) varies depending on the positional relationship between the current position (Xg, Yg) of the mirror 14 and the target position (Xc, Yc). The correction value (Xh, Yh) can be changed for each combination of the area of the current position (Xg, Yg) of the mirror 14 and the area of the target position (Xc, Yc). As a result, when the mirror 14 is automatically tilted from the current position (Xg, Yg) to the target position (Xc, Yc), an error occurs in the stop position of the mirror 14 with respect to the target position (Xc, Yc). This can be further suppressed, and the mirror 14 can be further prevented from being automatically tilted from the stop position to the target position (Xc, Yc) again.

  Moreover, the error of the stop position of the mirror 14 with respect to the target position (Xc, Yc) is stored as a correction value (Xh, Yh) for each order of the vertical direction and the inside / outside direction in which the mirror 14 is tilted. Therefore, the vertical direction in which the mirror 14 is tilted in response to the error of the stop position of the mirror 14 with respect to the target position (Xc, Yc) depending on the order of the vertical direction in which the mirror 14 is tilted and the inside and outside directions. And the correction value (Xh, Yh) can be changed for each order of the inner and outer directions. As a result, when the mirror 14 is automatically tilted from the current position (Xg, Yg) to the target position (Xc, Yc), an error occurs in the stop position of the mirror 14 with respect to the target position (Xc, Yc). This can be further suppressed, and the mirror 14 can be further prevented from being automatically tilted from the stop position to the target position (Xc, Yc) again.

  Further, every time the mirror 14 is automatically tilted from the current position (Xg, Yg) to the target position (Xc, Yc), an error with respect to the target position (Xc, Yc) of the stop position of the mirror 14 is stored. The correction values (Xh, Yh) are updated. For this reason, the mirror 14 is moved from the current position (Xg, Yg) to the target position (Xc) in response to the error of the stop position of the mirror 14 with respect to the target position (Xc, Yc) fluctuating due to aging of the mirror surface adjustment unit 20. , Yc), the correction value (Xh, Yh) can be updated each time the tilt is automatically made. As a result, when the mirror 14 is automatically tilted from the current position (Xg, Yg) to the target position (Xc, Yc), an error occurs in the stop position of the mirror 14 with respect to the target position (Xc, Yc). This can be further suppressed, and the mirror 14 can be further prevented from being automatically tilted from the stop position to the target position (Xc, Yc) again.

  In this embodiment, whenever the mirror 14 is automatically tilted from the current position (Xg, Yg) to the target position (Xc, Yc), the ECU 30 detects the target position (Xc) of the stop position of the mirror 14. , Yc), the X coordinate and Y coordinate of the error are stored, and the correction values Xh and Yh are updated. However, when the mirror 14 is automatically tilted from the current position (Xg, Yg) to the target position (Xc, Yc), the ECU 30 causes an error of the stop position of the mirror 14 relative to the target position (Xc, Yc). One of the X coordinate and the Y coordinate may be stored, and only one of the correction values Xh and Yh may be updated.

  For example, when the mirror 14 is tilted only in the vertical direction when the mirror 14 is automatically tilted from the current position (Xg, Yg) to the target position (Xc, Yc), the stop position of the mirror 14 Since an error with respect to the target position (Xc, Yc) hardly occurs in the Y coordinate, only the X coordinate of the error may be stored and only the correction value Xh may be updated. On the other hand, when the mirror 14 is automatically tilted from the current position (Xg, Yg) toward the target position (Xc, Yc), if the mirror 14 is tilted only in the inner and outer directions, the stop position of the mirror 14 Since the error with respect to the target position (Xc, Yc) hardly occurs in the X coordinate, only the Y coordinate of the error may be stored and only the correction value Yh may be updated. Thereby, the process of ECU30 can be simplified.

  In the present embodiment, the mirror 14 is tilted when the shift lever device 42 is operated and the shift range of the automatic transmission 40 is changed with respect to the “R” range. The present invention was applied. However, the present invention can also be applied to other uses such as a so-called “turn interlocking type” in which the mirror 14 is tilted in conjunction with a turn switch when the vehicle turns right or left.

  Furthermore, in the present embodiment, the mirror surface adjustment unit 20 tilts the mirror 14 in the vertical direction and the inner / outer direction which are orthogonal to each other. However, the mirror surface adjustment unit 20 should just tilt the mirror 14 to the one direction and other direction which mutually cross | intersect.

  In the present embodiment, the present invention is applied to the vehicle door mirror device 10. However, the present invention may be applied to other outside or inside mirror devices.
