  Hereinafter, an angle control device and an angle control method for a vehicle door mirror according to an embodiment of the present invention will be described. As shown in FIG. 1, an angle control device 1 for a vehicle door mirror according to an embodiment of the present invention includes an acceleration detection means 11, a steering angle range detection means 12, a winker operation detection means 13, and a control output means 17. And.

  The acceleration detecting means 11 is a detecting means for detecting that the vehicle is accelerating at a certain acceleration or more within a certain time from a certain speed. The acceleration detecting means 11 itself may have an acceleration sensor for detecting the acceleration of the vehicle. The acceleration detecting means 11 itself does not have an acceleration sensor, receives acceleration information from the ECU of the vehicle, and is constant from a constant speed. It may be detected that the vehicle is accelerating at a certain acceleration or more in time. The acceleration detected by the acceleration detecting means 11 is set in advance. For example, when the acceleration is accelerated from 30 km / h to 50 km / h within 10 seconds, a signal that becomes the first factor of the main line merging state is output.

  The acceleration detecting means 11 detects that the vehicle is accelerating on the branch line when the vehicle joins a multi-lane road where the speed of the vehicle running on the main line such as an expressway or an urban bypass is high. . At this time, at a position away from the main line of the branch line, the acceleration is detected when the vehicle speed is 30 km and the vehicle accelerates within a preset number of seconds (for example, 10 seconds) to 50 km / h or more. ing. This is because accelerating to 50 km / h is very fast just before merging to the main line, so it is necessary to confirm safety at the subsequent merging.

  The steering angle range detection means 12 is a detection means for detecting that the steering angle of the vehicle steering is within a certain range within a certain time. The steering angle range detection means 12 obtains steering angle information from a rotation sensor attached to the steering via an ECU that handles information on the steering angle of the vehicle, for example.

  For example, when the steering angle range detection means 12 detects that the steering angle of the steering is within 30 degrees within 5 seconds, the steering angle range detection means 12 outputs a signal that becomes the second factor of the main line merging state.

  The steering angle range detection means 12 generally enters obliquely with respect to the main line immediately before entering the main line from the branch line, but the vehicle itself almost straightly joins the main line, so that the steering wheel Therefore, if the steering angle range is within a certain range, it plays the role of determining that it is one of the situations of entering the main line from the branch line.

  The blinker operation detection means 13 is a detection means for detecting that the turn signal for turning right of the vehicle is activated within a predetermined time. The turn signal operation detection means 13 obtains the operation information of the right turn signal from an ECU that performs control related to the turn signal of the vehicle, for example.

  For example, when the operation signal of the right turn signal is input within 5 seconds, the turn signal operation detection means 13 outputs a signal that becomes the third factor of the main line merging state.

  The winker operation detection means 13 is a detection means for detecting that the right turn winker has been operated as described above, and the logical product of the determination result by the acceleration detection means 11 and the determination result by the steering angle range detection means 12 described above. Used when taking

  The timer 15 is for managing the above-mentioned fixed time, and is used for sequentially counting the time and allowing the signals that are the first to third factors in real time.

  Based on the detection results of the acceleration detection means 11, the steering angle range detection means 12, and the winker operation detection means 13, the control output means 17 opens the vehicle door mirror angle outward from the predetermined angle by a certain angle. It is an output means for outputting a control signal to be controlled.

  The control output means 17 is provided with a handle mounting position input means 18. The opening angle of the door mirror is made different between the right door mirror attached to the right handle and the right door mirror attached to the left handle by the handle attachment position input means 18. Specifically, the opening angle of the right door mirror may be further increased by, for example, 2 to 10 degrees for 10 seconds. Preferably, whether the vehicle is a right handle or a left handle by the handle mounting position input means 18. By setting in advance, it is preferable to change the opening angle of the right side door mirror of the right-hand drive vehicle and the left-hand drive vehicle to optimum angles. Specifically, when the vehicle is a right steering wheel, the angle is preferably 2 to 6 degrees, more preferably 2 to 6 degrees, which is a relatively small angle. Further, when the vehicle is a left steering wheel, the angle is preferably 6 degrees to 10 degrees, more preferably a relatively large angle, from 2 degrees to 10 degrees. This is because the driver's seating position is different between the right-hand drive vehicle and the left-hand drive vehicle, so that it is possible to confirm diagonally backward only with the right door mirror at an appropriate opening angle.

  Thus, the logical product of the detection results by the acceleration detection means 11, the steering angle range detection means 12, and the winker operation detection means 13 are all 1 (when all conditions are satisfied), and the driving situation at that time is the expressway. And the opening angle of the right door mirror is opened for a certain amount of time for a certain amount of time, so that the vehicle can be driven at a relatively high speed, such as a highway or a bypass road. When joining the main road that runs on the main line from the side, you can eliminate the blind spot behind the right door mirror and join the main line while checking the vehicle diagonally only with the right door mirror without looking directly .

  Further, only when the logical product of the detection results by the acceleration detection means 11, the steering angle range detection means 12, and the winker operation detection means 13 is all 1, the opening angle of the right door mirror is opened by a certain amount, for example, When you turn right at the road intersection and stop at a red light and turn right, the right turn signal is displayed and at the same time the angle of the right door mirror is prevented from opening unnecessarily. In addition, when the vehicle is approaching an intersection on a general road, the angle of the right door mirror is prevented from opening unnecessarily when decelerating at a green light and turning right. Further, when the right turn signal is taken out when moving from the driving lane to the overtaking lane when running on the highway at a constant speed, the right door mirror is prevented from opening more than necessary.

  Then, the angle control method of the door mirror for vehicles which concerns on one Embodiment of this invention is demonstrated based on a flowchart.

  When the vehicle door mirror angle control method is started, as shown in FIG. 2, when the right door mirror angle control routine of the vehicle is started (step S11), the vehicle accelerates from a constant speed to a certain acceleration within a certain time. It is determined whether or not (step S12). If the vehicle has not accelerated at a certain acceleration or more from a certain speed within a certain time, this step S12 is repeated.

  When the vehicle is accelerating at a certain acceleration or more from a certain speed within a certain time, it is determined whether the steering angle of the vehicle steering is within a certain range within a certain time (step S13). If the steering angle of the vehicle steering is not within a certain range within a certain time, this step S13 is repeated.

  If it is determined that the steering angle of the vehicle is within a certain range within a certain time, it is determined whether or not the turn right turn signal for the vehicle is activated within the certain time (step S14).

  If the turn signal for turning right of the vehicle does not operate within a certain time, step S14 is repeated. When the turn signal for the right turn of the vehicle is activated within a certain period of time, a control signal for controlling the right side mirror of the vehicle to open outward from the predetermined angle by a certain angle for a certain period of time is sent to the right side door mirror drive unit (see FIG. (Step S15).

  These steps S12 to S15 are repeated until the engine is stopped by turning off the vehicle ignition switch (step S16), and at the same time as the engine is stopped, this routine is ended (step S17).

  As a second modification of the above-described embodiment, when the handle mounting position input means 18 is used, the following subroutine is executed between step S14 and step S16 as shown in FIG. Specifically, when the condition of step S14 is satisfied, it is determined whether or not the vehicle is a right steering wheel (step S14A). If it is determined in step S14A that the vehicle is a right steering wheel, the door mirror on the right side of the vehicle is opened for a certain time by an opening angle suitable for the right steering wheel (step S15A), and the process proceeds to step S16. On the other hand, if it is determined in step S14A that the vehicle is a left steering wheel, the door mirror on the right side of the vehicle is opened for a certain time by an opening angle suitable for the left steering wheel (step S15B), and the process proceeds to step S16.

  Then, the 1st modification of embodiment of the angle control apparatus of the door mirror for vehicles mentioned above is demonstrated. In addition, about the structure equivalent to embodiment mentioned above, a corresponding code | symbol is attached | subjected and detailed description is abbreviate | omitted, and the component newly added in this 1st modification is demonstrated in detail.

  As shown in FIG. 4, the angle control device 2 for a vehicle door mirror according to the first modification includes a speed detection means 14 for detecting that the vehicle is below a certain speed within a certain time, and within a certain time. Steering angle range detecting means 12 for detecting that the steering angle of the vehicle steering is within a certain range; and a winker operation detecting means 13 for detecting that the turn signal for the left turn of the vehicle is actuated within a certain time. ing.

  Then, the speed detection means detects that the vehicle is within a certain speed (for example, 40 km / h) within a certain time (for example, 10 seconds), and the steering angle range detection means 12 for a certain time (for example, 5 seconds). ) To detect that the steering angle of the vehicle is within a certain range (for example, 30 degrees) and that the turn signal for the left turn of the vehicle has been activated within a certain time (for example, 5 seconds). When the means 13 detects, control which outputs the control signal which controls the angle of the door mirror on the left side of the vehicle to open outward from the predetermined angle (for example, 2 to 10 degrees) from the predetermined angle for a certain time (for example, 10 seconds) Output means 17 'is further provided.

  Next, an angle control method for a vehicle door mirror according to a modification of the embodiment of the present invention will be described based on the flowchart shown in FIG.

  This vehicle door mirror angle control method is a routine for preventing a bicycle or the like from being involved when making a left turn. When this routine is started (step S21), it is determined whether or not the vehicle is below a certain speed within a certain time. (Step S22). If the vehicle is not below a certain speed within a certain time, it is determined that the vehicle is not decelerating to turn left at the intersection, and this step S22 is repeated.

  If it is determined that the vehicle is below a certain speed within a certain time, it is determined that the vehicle is decelerating to turn left at the intersection or stopped at the intersection because of a left turn. It is determined whether the steering angle is within a certain range (step S23). If the steering angle of the vehicle steering is not within a certain range within a certain time, it is determined that the vehicle is not in a situation of turning left at the intersection, and this step S23 is repeated.

  If it is determined in step S23 that the steering angle of the vehicle steering is within a certain range within a certain time, it is determined whether or not the left turn turn signal of the vehicle has been actuated within the certain time (step S24). When the turn signal for turning left of the vehicle does not operate within a predetermined time, step S24 is repeated.

  If it is determined in step S24 that the turn signal for the left turn of the vehicle has been activated within a predetermined time, a control signal for driving the left door mirror is opened so that the angle of the left side door mirror of the vehicle is opened outward from the predetermined angle by a predetermined angle. Output.

  Then, these steps 22 to S25 are repeated until the engine is stopped by turning off the ignition switch of the vehicle (step S26), and this routine is ended at the same time as the engine is stopped (step S27).

  When the handle mounting position input information is used, the following subroutine is executed between step S24 and step S26. Specifically, as shown in FIG. 6, when the condition of step S14 is satisfied, it is determined whether or not the vehicle is a right steering wheel (step S24A). If the vehicle is a right steering wheel in step S24A, the door mirror on the left side of the vehicle is opened for a certain period of time by an opening angle suitable for the right steering wheel (step S25A), and the process proceeds to step S26. On the other hand, if the vehicle is a left steering wheel in step S24A, the door mirror on the left side of the vehicle is opened for a certain time by an opening angle suitable for the left steering wheel (step S25B), and the process proceeds to step S26.

  Note that the opening angle of the right door mirror of the right-hand drive vehicle and the opening angle of the left door mirror of the left-hand drive vehicle are appropriately selected based on the information input by the handle mounting position input means 18 described above.

  In the above-described embodiment and its modifications, the control output means 17 and 17 ′ may include a winker interlocking opening switch 21. The winker interlocking opening switch 21 determines that the right winker has been operated by the winker operation detecting means 13 without controlling the opening angle of the right door mirror based on the determination results of the acceleration detecting means 11 and the steering angle range detecting means 12. In this case, the opening angle of the right door mirror is temporarily opened by a certain amount by a certain angle for a certain time.

  That is, in the flowchart in FIG. 2, the determination results of these two steps are all determined as YES without performing the condition determinations in steps S12 and S13, and the process proceeds to the subsequent step S14. Further, in the flowchart in FIG. 5, the determination results of these two steps are all set to YES without proceeding to the subsequent step S24 without performing the condition determination of step S22 and step S23.

  As a result, when approaching a place where the number of junctions from the branch line to the main line is high, such as a junction on an expressway, the turn signal interlocking switch 21 is operated to release the right turn signal and the opening angle of the right door mirror is automatically adjusted. Therefore, since the vehicle is opened by a certain amount for a certain time, the usability of the angle control devices 1 and 2 for the vehicle door mirror can be improved.

  Then, the effect | action of embodiment mentioned above and its various modifications is demonstrated. FIG. 7 is a diagram for explaining the above-described embodiment and its modifications, and shows a state in which the vehicle is a right handle and the door mirror is at a normal angle. In FIG. 7, an arrow 101 indicates the line of sight of the right door mirror 51 as viewed by the driver M, and an arrow 102 indicates the line of sight of the left door mirror 52 as viewed by the driver M.

  On the other hand, FIG. 8 is a figure which shows the action state of one Embodiment of this invention, and its modification. As is clear from a comparison between FIG. 7 and FIG. 8, the right door mirror 51 is opened at an angle of about 2 to 10 degrees so as to correspond to the above-described embodiment. Then, the line of sight of the right door mirror 51 of the driver M has changed from a dotted line to an arrow 101a indicated by a solid line, and it can be seen that the vehicle obliquely rearward can be confirmed from the rear view seen at a normal angle of the right side door mirror 51.

  Similarly, the left door mirror 52 is also opened from the normal state by about 2 degrees to 10 degrees as in the first modification of the above-described embodiment, and is more than the normal rear view as shown by the solid arrow 102a. It can be seen that the field of view behind the diagonal can be confirmed.

  FIG. 9 is a diagram for explaining the above-described embodiment and its modifications, and shows a state in which the vehicle is the left handle and the door mirrors 61 and 62 are at a normal angle. In FIG. 9, the arrow 201 indicates the line of sight of the right door mirror 61 as viewed by the driver M, and the arrow 202 indicates the line of sight of the left door mirror 62 as viewed by the driver M.

  On the other hand, FIG. 10 is a figure which shows the operation state of one Embodiment of this invention, and its modification. As is clear from a comparison between FIG. 9 and FIG. 10, the right door mirror 61 is opened at an angle of about 2 to 10 degrees so as to correspond to the above-described embodiment. Then, the line of sight of the right door mirror 61 of the driver M has changed from a dotted line to an arrow 201a indicated by a solid line, and it can be seen that the vehicle obliquely rearward can be confirmed from the rear view seen from the normal angle of the right side door mirror 61. Similarly, the left-side door mirror 62 is also opened from the normal state by about 2 to 10 degrees as in the first modification of the above-described embodiment, and is further more than the normal rear view as indicated by the solid arrow 202a. It can be seen that the field of view behind the vehicle can be confirmed.

  FIG. 11 is an explanatory view for explaining the operation of the present invention when merging with the main road of a highway or a bypass using the vehicle door mirror angle control device and angle control method according to one embodiment of the present invention. As is clear from FIG. 11, when the vehicle is in the state (1), the right turn signal is operated. As a result, the angle control devices 1 and 2 for the vehicle door mirror determine that the vehicle is entering the main line together with the other conditions of the above-described embodiment, and the right door mirrors 51 and 61 are moved from, for example, 2 degrees. It opens at a position of 10 degrees (see the state of (2)), and the vehicle advances to the state of (3) with this opening angle. Thus, as is apparent from FIG. 11, the driver M reliably recognizes the presence of the vehicle A traveling in the traveling lane from the rear in the movement process from the state (2) to the state (3). Can enter the main line with peace of mind.

  Then, after the vehicle has entered the main line, the right turn signal is returned to shift to the normal running state as shown in the state (4). In this state, since the right door mirror 51 has returned to the normal opening angle, the approach of the vehicle B traveling in the overtaking lane can be confirmed with the right door mirror 51.

  As described above, according to the angle control device and the angle control method for a vehicle door mirror according to the present invention, the vehicle is running on the main line at a relatively high speed, for example, a highway or a main road such as a bypass while driving the vehicle. When joining the main road from the side, you can eliminate the blind spot behind the right door mirror and join the main line while checking the back without looking directly.

  Further, according to the present invention, the vehicle is accelerated within a certain time from a certain speed at a certain acceleration or more, the steering angle of the vehicle steering is within a certain range, and the turn signal for turning the vehicle right is activated. Since the angle of the right door mirror is set to open outward from the predetermined angle by a certain angle for a certain time, the right door mirror is not opened unnecessarily when turning right at the intersection of a general road, thereby improving usability.

  In addition, although the numerical value described in embodiment mentioned above is not limited to it, it shows an example which exhibits the effect | action of this invention, and is not limited within this numerical range.
