Title: Viewing control device for vehicle

Description:
TECHNICAL FIELD 
     The present invention relates to a viewing control device for a vehicle that controls a viewing device for viewing the periphery of a vehicle, such as a door mirror or a camera or the like. 
     BACKGROUND ART 
     Japanese Utility Model Application Laid-Open (JP-U) No. H6-23829 proposes a rearview mirror device for a vehicle that has a mirror driving mechanism that obtains a turn direction signal from a direction indicator or a steering wheel, and moves a rearview mirror in respective directions. 
     Further, Japanese Patent Application Laid-Open (JP-A) No. 2010-208374 proposes an angle control device of a door mirror for a vehicle that has acceleration sensing means for sensing that a vehicle is accelerating at greater than or equal to a given acceleration from a given speed and within a given time period, steering angle range sensing means for sensing that the steering angle of the steering of the vehicle is within a given range within a given time period, and blinker operation sensing means for sensing that the right turn blinker of the vehicle has operated within a given time period, and in which, in a case in which it is sensed by these sensing means that the vehicle is accelerating at greater than or equal to a given acceleration from a given speed and within a given time period, and that the steering angle of the steering of the vehicle is within a given range within a given time period, and that the right turn blinker of the vehicle has operated within a given time period, effects control so as to open up, toward the outer side, the angle of the right side door mirror of the vehicle from a predetermined angle for a given time period and by a given angle. 
     SUMMARY OF INVENTION 
     Technical Problem 
     However, in a case in which it is desired to confirm that the body will not be scraped on a narrow road, if changing of the viewing range is carried out as in JP-U No. H6-23829 and JP-A No. 2010-208374, the body side cannot be viewed and there will be control that runs counter to the intent of the vehicle occupant, and therefore, there is room for improvement. 
     The present invention was made in view of the above-described circumstances, and an object thereof is to suppress control that runs counter to the intent of a vehicle occupant in a case in which a viewing range is changed interlockingly with turning. 
     Solution to Problem 
     In order to achieve the above-described object, the present invention includes: a changing portion that, interlockingly with turning of a vehicle, changes a viewing range of a periphery of the vehicle with respect to a vehicle occupant; and a control section that, in a case in which a predetermined condition for viewing a body side of the vehicle is established, controls the changing portion so as to prohibit or stop changing by the changing portion. 
     In accordance with an aspect of the present invention, at the changing portion, the viewing range of the periphery of the vehicle, with respect to the vehicle occupant, is changed interlockingly with turning of the vehicle. For example, in a case in which the periphery of the vehicle is viewed by a mirror surface or a camera or the like, the changing portion changes the viewing range by driving an actuator such as a motor or the like so as to change the position of the mirror surface or the direction of imaging. Or, the changing portion changes the viewing range by changing the position that is cut-out from a captured image. 
     Further, in a case in which a predetermined condition for viewing the body side of the vehicle is established, at the control section, the changing portion is controlled so as to prohibit or stop the changing by the changing portion. Due thereto, in a case in which it is desired to view the body side, changing of the viewing range interlockingly with turning can be suppressed, and therefore, control that runs counter to the intent of the vehicle occupant can be suppressed. 
     Note that the control section may control the changing portion so as to prohibit changing by the changing portion in a case in which, before a start of changing by the changing portion, a preset first predetermined condition is established as the predetermined condition. Or, the control section may control the changing portion so as to stop changing by the changing portion in a case in which, in a midst of changing of the viewing range by the changing portion, a preset second predetermined condition is established as the predetermined condition. In this case, after stopping changing by the changing portion, the control section may further control the changing portion such that the viewing range becomes a viewing range before changing. 
     Further, the predetermined condition may include at least a condition that a turning radius is less than a predetermined value. Further, there may be utilized a structure in which the first predetermined condition includes a first condition that is that a vehicle speed during straight forward traveling before a turn switch is turned on is lower than a preset first vehicle speed, a second condition that is that a vehicle speed at a time when the vehicle starts turning is lower than a preset second vehicle speed, a third condition that is that a turning radius is less than a predetermined value, and a fourth condition that is that a steering angle is greater than a predetermined value, and the first predetermined condition is established in a case in which the respective conditions are all established before a start of changing by the changing portion. Further, there may be utilized a structure in which the second predetermined condition includes a third condition that is that a turning radius is less than a predetermined value, and a fourth condition that is that a steering angle is greater than a predetermined value, and the second predetermined condition is established in a case in which both the third condition and the fourth condition are established in a midst of changing of the viewing range by the changing portion. 
     Advantageous Effects of Invention 
     As described above, in accordance with the present invention, there is the effect that control that runs counter to the intent of the vehicle occupant can be suppressed.

     DESCRIPTION OF EMBODIMENTS 
     An example of an embodiment of the present invention is described in detail hereinafter with reference to the drawings. Note that, hereinafter, a door mirror control device for a vehicle is described as an example of the viewing control device for a vehicle of the present invention.  FIG. 1  is an exterior view of a door mirror device for a vehicle that is the object of control of the door mirror control device relating to the embodiment of the present invention. Further,  FIG. 2  is a cross-sectional view (a cross-sectional view along line  2 - 2  of  FIG. 1 ) in which main portions of the door mirror device for a vehicle are seen from the vehicle vertical direction upper side (the vehicle upper side). Note that, in the drawings, the vehicle front side is indicated by arrow FR, a vehicle transverse direction outer side (the vehicle left side) is indicated by arrow OUT, and the upper side is indicated by arrow UP. 
     A door mirror device  30  for a vehicle is installed at the outer side of the front end of a vertical direction intermediate portion of a door (a front door) of the vehicle. 
     As shown in  FIG. 1 , the door mirror device  30  for a vehicle has a visor  32  that is substantially shaped as a rectangular parallelepiped container and serves as an outer peripheral member. The door mirror device  30  for a vehicle is installed at the door due to the vehicle transverse direction inner side portion of the visor  32  being supported at the door (the vehicle body side). Further, the interior of the visor  32  opens toward the vehicle rear side. 
     A mirror  34  that is substantially shaped as a rectangular flat plate is provided within the visor  32 . The mirror  34  is disposed in the opening portion of the visor  32 . A mirror main body  36  (mirror body) is provided at the vehicle rear side portion of the mirror  34 . The vehicle rear side surface that is a reflecting film of the mirror main body  36  is made to be a mirror surface  36 A. Further, the vehicle front side and the outer periphery of the mirror main body  36  are covered by a mirror holder  38  (a mirror holder outer). 
     As shown in  FIG. 2 , a mirror surface adjusting unit  40  that is electrically operated is provided within the visor  32 . 
     A case  42  that is substantially shaped as a hemispherical container is provided at the vehicle front side portion of the mirror surface adjusting unit  40 . The interior of the case  42  opens toward the vehicle rear side. The case  42  is supported by the visor  32 , and, due thereto, the mirror surface adjusting unit  40  is supported by the visor  32 . 
     A tilting body  44  (mirror holder inner) is provided at the vehicle rear side portion of the mirror surface adjusting unit  40 . The tilting body  44  is held by the case  42  so as to be able to tilt (swing, pivot). A sliding tube  44 A that is substantially shaped as a cylindrical tube is provided at the tilting body  44 . The diameter of the sliding tube  44 A becomes gradually smaller toward the vehicle front side, and the sliding tube  44 A is made to be able to slide with respect to the peripheral wall of the case  42 . A mounting plate  44 B that is substantially disc shaped is provided integrally with the vehicle rear side end of the sliding tube  44 A. The mirror holder  38  of the mirror  34  is detachably mounted to the vehicle rear side of the mounting plate  44 B. Due thereto, the mirror  34  can be tilted integrally with the tilting body  44  and with respect to the case  42 , with the center of gravity position of the mirror  34  (the surface central position of the mirror surface  36 A) being the center. 
     An up/down motor (not illustrated) and an in/out motor  22  that serves as one element of a changing portion are fixed to the interior of the case  42 . An up/down rod (not illustrated) and an in/out rod  48  that are respectively rod-shaped are connected to the up/down motor and the in/out motor  22  via gear mechanisms  50  that serve as mechanical mechanisms. The up/down rod and the in/out rod  48  are held within the case  42  so as to be able to slide (move) in the vehicle longitudinal direction (the axial direction). The distal end (the vehicle rear side end) of the up/down rod is rotatably held at the mounting plate  44 B at the upper side (or may be at the lower side) of the center of gravity position of the mirror  34 . The distal end (the vehicle rear side end) of the in/out rod  48  is rotatably held at the mounting plate  44 B at the vehicle transverse direction outer side (or may be at the vehicle transverse direction inner side) of the center of gravity position of the mirror  34 . 
     The up/down motor and the in/out motor  22  are electrically connected via mirror surface driving drivers  20  to an ECU  12  (a mirror ECU) that serves as a changing portion and a control section. The ECU  12  is provided within the visor  32  or at the vehicle body side. An adjustment operation device  26  is electrically connected to the ECU  12 . When the adjustment operation device  26  is operated by a vehicle occupant (the driver in particular) of the vehicle, due to control of the ECU  12 , the mirror surface adjusting unit  40  is operated, and the up/down motor and the in/out motor  22  are driven. Due thereto, the up/down rod and the in/out rod  48  are slid in the vehicle longitudinal direction, and the tilting body  44  and the mirror  34  are tilted with respect to the case  42 . Due thereto, the tilted position of the mirror  34  is adjusted, and the angle of the mirror surface  36 A of the mirror  34  (the direction in which the mirror surface  36 A faces) is adjusted. 
     When the up/down rod is slid toward the vehicle front side, the tilting body  44  and the mirror  34  are tilted upward (in an upwardly-facing direction), and the mirror surface  36 A of the mirror  34  is tilted in an upwardly-facing direction. When the up/down rod is slid toward the vehicle rear side, the tilting body  44  and the mirror  34  are tilted downward (in a downwardly-facing direction), and the mirror surface  36 A of the mirror  34  is tilted in a downwardly-facing direction. When the in/out rod  48  is slid toward the vehicle front side, the tilting body  44  and the mirror  34  are tilted outward (in an outwardly-facing direction), and the mirror surface  36 A of the mirror  34  is tilted in a direction of facing outwardly in the vehicle transverse direction. When the in/out rod  48  is slid toward the vehicle rear side, the tilting body  44  and the mirror  34  are tilted inward (in an inwardly-facing direction), and the mirror surface  36 A of the mirror  34  is tilted in a direction of facing inwardly in the vehicle transverse direction. 
     As shown in  FIG. 2 , an up/down sensor (not illustrated) and an in/out sensor  24  are provided at the case  42 . The up/down sensor and the in/out sensor  24  respectively are electrically connected to the ECU  12 . A housing  25  that is substantially shaped as a rectangular parallelepiped box is provided at the up/down sensor and the in/out sensor  24 , respectively. The up/down sensor and the in/out sensor  24  are fixed to the case  42  due to housings  25  being fixed to the outer side of the bottom wall of the case  42 . 
     Detecting rods  46  that are rod-shaped are provided at the housings  25  so as to be slidable in the vehicle longitudinal direction (the axial direction). The detecting rods  46  project-out toward the vehicle rear side from the housings  25  and are urged toward the vehicle rear side. The detecting rods  46  pass-through the bottom wall of the case  42 , and are inserted into the interior of the case  42 . The detecting rods  46  of the up/down sensor and the in/out sensor  24  are disposed coaxially with and at the vehicle front sides of the up/down rod and the in/out rod  48 , respectively. The distal ends (the vehicle rear side ends) of the detecting rods  46  of the up/down sensor and the in/out sensor  24  are, by urging forces, made to contact the proximal ends (the vehicle front side ends) of the up/down rod and the in/out rod  48  respectively. The detecting rods  46  of the up/down sensor and the in/out sensor  24  can always slide in the vehicle longitudinal direction integrally with the up/down rod and the in/out rod  48 , respectively. Therefore, due to the up/down sensor and the in/out sensor  24  detecting the slid positions in the vehicle longitudinal direction of the detecting rods  46  respectively, the up/down sensor and the in/out sensor  24  detect the slid positions in the vehicle longitudinal direction of the up/down rod and the in/out rod  48  respectively, and detect the tilted position of the mirror  34  in the up/down direction and the in/out direction. 
       FIG. 3  is a block drawing showing the structure of the control system of the door mirror control device  10  for a vehicle relating to the present embodiment. 
     As described above, the door mirror control device  10  for a vehicle has the ECU  12 . The ECU  12  is structured by a microcomputer in which a CPU  12 A, a ROM  12 B, a RAM  12 C and an I/O (input/output interface)  12 D are respectively connected to a bus  12 E. 
     A turning-interlocked mirror control program that is described later, various types of data such as various types of tables, formulas and the like, and the like are stored in the ROM  12 B. Due to the program that is stored in the ROM  12 B being expanded in the RAM  12 C and being executed by the CPU  12 A, control that moves the mirror surface  36 A of the mirror  34  interlockingly with turning is carried out. Note that, as an example, the turning-interlocked mirror control program is stored as the program that is stored in the ROM  12 B, but other programs also are stored. 
     A vehicle speed sensor  14 , a turn switch  16 , a steering angle sensor  18 , a right side mirror surface driving driver  20 R, a left side mirror surface driving driver  20 L, a right side in/out sensor  24 R, a left side in/out sensor  24 L, and the above-described adjustment operation device  26  are connected to the I/O  12 D. 
     The vehicle speed sensor  14  detects the traveling speed of the vehicle (hereinafter called the vehicle speed), and the results of detection are inputted to the ECU  12 . 
     The turn switch  16  is a switch for instructing lighting of the turn signals, and instructions for lighting the left and right turn signals are inputted to the ECU  12 . Due thereto, on the basis of the signals of the turn switch  16 , the ECU  12  judges the intent of the vehicle occupant to turn. 
     The steering angle sensor  18  detects the steering angle (hereinafter called steering angle) of the steering, and inputs the results of detection of the steering angle to the ECU  12 . 
     A right side up/down motor  23 R and a right side in/out motor  22 R are connected to the right side mirror surface driving driver  20 R. The right side up/down motor  23 R and the right side in/out motor  22 R are driven in accordance with instructions of the ECU  12 . Further, a left side up/down motor  23 L and a left side in/out motor  22 L are connected to the left side mirror surface driving driver  20 L. The left side up/down motor  23 L and the left side in/out motor  22 L are driven in accordance with instructions of the ECU  12 . 
     The right side in/out sensor  24 R detects the tilted position of the right side mirror  34  in the in/out direction, and the left side in/out sensor  24 L detects the tilted position of the left side mirror  34  in the in/out direction, and they respectively input the results of detection to the ECU  12 . Note that, although not illustrated, up/down sensors as well are provided in correspondence with the respective left and right mirrors  34 , and are connected to the ECU  12 . 
     Here, the turning-interlocked mirror control that serves as the changing portion and is carried out at the door mirror control device  10  for a vehicle relating to the present embodiment is described.  FIG. 4  is a drawing for explaining the turning-interlocked mirror control. 
     The turning-interlocked mirror control is carried out due to the ECU  12  executing the turning-interlocked mirror control program that is stored in the ROM  12 B. 
     In a case of carrying out turning such as a right turn or a left turn or the like, the vehicle occupant confirms the door mirror device  30  for a vehicle, and confirms turn collision objects such as bicycles and the like. However, when the turn is started, in accordance with the turning, the viewing range of the periphery of the vehicle, with respect to the vehicle occupant, of the door mirror device  30  for a vehicle moves outside of the region where objects of confirmation as turn collision objects, such as bicycles or the like, exist. 
     Because objects of confirmation come out of the viewing range at the time of turning of the vehicle in this way, in the turning-interlocked mirror control, control is carried out to tilt the mirror surface  36 A of the mirror  34  and change the viewing range, interlockingly with the turning of the vehicle. 
     Concretely, in a usual state such as a state of traveling straight forward or the like, the vehicle occupant is at a position of viewing region A of the viewing range that is shown in  FIG. 4  and is set in advance. Here, at the time of a turn, the amount of turning is detected from the results of detection of the vehicle speed sensor  14  and the steering angle senor  18 . Then, the ECU  12  controls the driving of the in/out motor  22  so as to tilt the mirror surface  36 A and move the region A of the viewing range in the direction of the dashed line in  FIG. 4 , in accordance with the detected amount of turning. Due thereto, as shown in  FIG. 5 , in accordance with the amount of turning, the viewing range is changed from region A 0  to regions A 1 , A 2 , and confirmation of turn collision objects at the time of turning can be carried out reliably. Note that, in the present embodiment, the condition for starting the turning-interlocked mirror control is, as an example, starting in a case in which the turn switch  16  is on and the steering angle is greater than or equal to a preset threshold value (e.g., 4° or the like). Further, tilting of the mirror surface  36 A that corresponds to the amount of turning is controlled by storing, in the ECU  12  and in advance, amounts of movement of the mirror surface  36 A that correspond to amounts of turning, and reading-out an amount of movement that corresponds to the amount of turning. 
     Note that, in the present embodiment, description is given, as an example, of a case in which the turn switch  16  being on and a steering angle that is greater than or equal to a predetermined steering angle being detected are the condition for starting the turning-interlocked mirror control. However, the change condition is not limited to this. For example, the results of detection of another sensor, such as an acceleration sensor or the like, or the like may be used as the start condition. 
     By the way, as described above, confirmation of turn collision objects can be carried out reliably at the time of turning, by carrying out the turning-interlocked mirror control. However, in a case of carrying out a left turn on a narrow road, there are cases in which the need to view the body side of the vehicle is strong. 
     For example, when the turning-interlocked mirror control is carried out as described above in the case of carrying out a left turn on a narrow road, as shown in  FIG. 6A , the space between the body and the wall falls outside of the viewing range, and the gap between the body and the wall cannot be confirmed. 
     Here, in the present embodiment, it is judged whether or not the body side is to be seen, and, in a case in which the body side is to be seen, the turning-interlocked mirror control is prohibited or stopped. For example, in a case in which a condition for carrying out the turning-interlocked mirror control is established, the transition to the turning-interlocked mirror control is prohibited in a case in which a predetermined condition for viewing the body side is established. Further, in a case in which a predetermined condition for viewing the body side is established in the midst of the turning-interlocked mirror control, the turning-interlocked mirror control is stopped, and control is carried out to return the viewing range to the original position. Due thereto, in a case in which it is desired to view the body side on a narrow road or the like, as shown in  FIG. 6B , changing of the viewing range by the turning-interlocked mirror control is not carried out. Therefore, the gap between the body and the wall can be confirmed, and control that runs counter to the intent of the vehicle occupant can be suppressed. 
     Note that, as predetermined conditions for viewing the body side, there are a first predetermined condition that is before the turning-interlocked mirror control is carried out, and a second predetermined condition that is in the midst of the turning-interlocked mirror control. 
     In the present embodiment, the first predetermined condition includes a first condition through a fourth condition that are described hereinafter, and the second predetermined condition includes a third condition and a fourth condition that are described hereinafter. 
     The first condition is the condition that the vehicle speed during traveling straight forward before the turn switch is turned on is lower than a first vehicle speed (e.g., 30 km/h or the like). The first condition is established in a case in which this vehicle speed is lower than the first vehicle speed. 
     The second condition is the condition that the vehicle speed at the time of starting to turn left (in the case of a right hand-drive vehicle) is lower than a second vehicle speed (e.g., 10 km/h or the like). The second condition is established in a case in which this vehicle speed is lower than the second vehicle speed. 
     The third condition is the condition that a predicted turning radius that is determined from the vehicle speed and the steering angle is less than a predetermined value (e.g., 7 m or the like). The third condition is established in a case in which the predicted turning radius is less than the predetermined value. 
     The fourth condition is the condition that the operated amount of the steering wheel (the steering angle) is greater than a predetermined value (e.g., 360°). The fourth condition is established in a case in which the operated amount is greater than the predetermined value. 
     Further, in a case in which all of the first condition through the fourth condition are established before the turning-interlocked mirror control, it is judged that the first predetermined condition for viewing the body side is established. In a case in which the third condition and the fourth condition are both established in the midst of the turning-interlocked mirror control, it is judged that the second predetermined condition is established. 
     Note that the first condition is an example of a condition for judging whether or not the road is a road of a low speed limit. Further, the second condition is an example of a condition for judging whether or not the road is a road that necessitates cautious turning (there is the possibility of scraping). Moreover, the third condition and the fourth condition are examples of conditions for judging whether or not the road is a road that necessitates turning of the steering wheel greatly from the time that the nose of the vehicle is jutted-out. Further, the present embodiment describes an example of using the above-described predetermined conditions, but the predetermined conditions may be other conditions. 
     Next, concrete processings that are carried out by the ECU  12  of the door mirror control device  10  for a vehicle, which relates to the present embodiment and is structured as described above, are described.  FIG. 7  is a flowchart showing an example of the flow of processings that are carried out by the ECU  12  of the door mirror control device  10  for a vehicle relating to the present embodiment. Note that explanation is given of an example in which the processings of  FIG. 7  are started in a case in which an unillustrated ignition switch is turned on. 
     First, in step  100 , the ECU  12  confirms the operating state of the turn switch  16 , and the routine moves on to step  102 . 
     In step  102 , the ECU  12  judges whether or not the turn switch  16  has been turned on. If this judgment is affirmative, the routine moves on to step  104 , and if this judgment is negative, the routine moves on to step  114 . 
     In step  104 , the ECU  12  judges whether or not the first predetermined condition for body side viewing is established. In this judgment, the ECU  12  judges whether or not all of the above-described first condition through the fourth condition are established. If this judgment is affirmative, the routine moves on to step  114  without carrying out mirror interlocking processing which is described later and is turning-interlocked mirror control. On the other hand, if the judgment is negative, the routine moves on to step  106 . 
     In step  106 , the ECU  12  judges whether or not the turn switch  16  has been turned off. If this judgment is affirmative, the routine moves on to step  114 , and is this judgment is negative, the routine moves on to step  108 . 
     In step  108 , the ECU  12  acquires the results of detection of the steering angle sensor  18 , and the routine moves on to step  110 . 
     In step  110 , the ECU  12  judges whether or not the steering angle that has been detected by the steering angle sensor  18  is greater than or equal to a predetermined steering angle. If this judgment is affirmative, the routine moves on to step  112 , and if this judgment is negative, the routine moves on to step  114 . 
     In step  112 , the ECU  12  carries out mirror interlocking processing, and the routine moves on to step  114 . Although details thereof are described later, in this mirror interlocking processing, for example, the ECU  12  determines the amount of turning from the respective results of detection of the steering angle sensor  18  and the vehicle speed sensor  14 , and controls driving of the in/out motor  22  so as to move the mirror surface  36 A to a preset position in accordance with the amount of turning. Concretely, in this control, control is carried out such that, the greater the amount of turning, the more the mirror surface  36 A is directed toward the outer side, and the better the region at the outer side can be viewed. Note that movement of the mirror surface  36 A that is interlocked with the turning may be controlled such that, when the steering angle starts to become smaller, the control ends and the mirror surface  36 A is moved to its original position. Or, movement of the mirror surface  36 A that is interlocked with the turning may be controlled such that, in a case in which the steering angle becomes a steering angle that is such that it is judged that there is a state of traveling straight forward, the control ends and the mirror surface  36 A is moved to its original position. Or, movement of the mirror surface  36 A that is interlocked with the turning may be controlled such that, in a case in which another condition is established, the control ends, and the mirror surface  36 A is moved to its original position. 
     Further, in step  114 , the ECU  12  judges whether or not the ignition switch has been turned off. If this judgment is negative, the routine returns to step  100  and the above-described processings are carried out. If this judgment is affirmative, the series of processings is ended. 
     The detailed flow of the mirror interlocking processing that is carried out in aforementioned step  112  is described next.  FIG. 8  is a flowchart that shows an example of the flow of mirror interlocking processings that are carried out at the ECU  12  of the door mirror control device for a vehicle relating to the present embodiment. 
     When there is a transition to the mirror interlocking processing, in step  200 , the ECU  12  acquires the results of detection of the steering angle sensor  18  and the vehicle speed sensor  14 , and the routine moves on to step  202 . 
     In step  202 , the ECU  12  computes the amount of turning from the detected vehicle speed and steering angle, and the routine moves on to step  204 . 
     In step  204 , the ECU  12  controls driving of the in/out motor  22  such that the mirror surface  36 A moves to a preset position in accordance with the amount of turning, and the routine moves on to step  206 . 
     In step  206 , the ECU  12  judges whether or not the second predetermined condition for body side viewing has been established. In this judgment, the ECU  12  judges whether or not the above-described third condition and fourth condition have both been established. If this judgment is negative, the routine moves on to step  208 , and if this judgment is affirmative, the routine moves on to step  210 . 
     In step  208 , the ECU  12  judges whether or not the mirror interlocking processing is to be ended. This judgment may be, as described above, a judgment as to whether or not the steering angle has started to become smaller, or may be a judgment as to whether or not there has become a steering angle that is such that it is judged that there is a state of traveling straight forward, or may be a judgment as to whether another condition has been established. In a case in which this judgment is negative, the routine returns to step  200  and the above-described processings are repeated. In a case in which this judgment is affirmative, the routine moves on to step  210 . 
     In step  210 , the turning-interlocked mirror control is stopped, and the ECU  12  controls the driving of the in/out motor  22  so as to move the mirror surface  36 A to its original position before the changing of the viewing range, and returns to the series of mirror interlocking processings, and the routine moves on to above-described step  114 . 
     By carrying out processings in this way, in the present embodiment, the viewing range is changed interlockingly with turning, and therefore, confirmation of turn collision objects can be carried out reliably. 
     On the other hand, in a situation in which it is described to confirm the body side such as on a narrow road or the like, the first predetermined condition is established before the turning-interlocked mirror control is carried out, and changing of the viewing range is not carried out. Therefore, the body side can be confirmed. Further, in the midst of the turning-interlocked mirror control, the second predetermined condition is established, the changing of the viewing range is stopped, and the viewing range is returned to the original viewing range. Therefore, the body side can be confirmed. Accordingly, control that runs counter to the intent of the vehicle occupant can be suppressed. 
     Note that the above-described embodiment describes the door mirror control device  10  for a vehicle as an example of the viewing control device for a vehicle, but the present invention is not limited to this. For example, the present invention may be applied to a structure that controls a rearview mirror or the like instead of the door mirror device  30  for a vehicle. Or, instead of the door mirror device  30  for a vehicle, the present invention may be applied to an imaging device such as a camera or the like, and may be applied to driving the imaging direction of the imaging device interlockingly with turning. Further, as the method of changing the viewing range in the case of application to an imaging device such as a camera or the like, the present invention may be applied to a structure in which the changing of the imaging direction is not changing by moving the camera, but that changes the display range for the vehicle occupant by cutting-out from the captured image. 
     Further, the above-described embodiment describes, as an example, a case in which, as the condition for starting the turning-interlocked mirror control, the turn switch  16  is turned on and a steering angle of greater than or equal to a predetermined steering angle is detected. However, navigation information of a navigation device, or the like, may be included in the condition for starting. 
     Further, the above-described embodiment describes, as an example, the first condition through the fourth condition as predetermined conditions for viewing the body side, but the present invention is not limited to this. For example, from navigation information of a navigation device, it may be judged whether or not a turn is being attempted on a narrow road. Or, the condition that the angular velocity of the steering wheel is less than a threshold value, or the condition that there is turning in which the nose of the vehicle is steered in the direction opposite the intended direction (e.g., a left turn that is accompanied by turning toward the right side before the left turn, or the like), or the condition that turning-back has arisen, or the like may be included as a predetermined condition as appropriate. 
     Further, the present invention is not limited to the above, and, other than the above, can, of course, be implemented by being modified in various ways within a scope that does not depart from the gist thereof.
