[0003] [Patent Document 1] JP 2013-119276 A Summary of the Invention [Problem to be solved by the invention]

[0004] In conventional side mirrors, when the vehicle is parked, such as when the ignition is turned off, the mirror surface of the side mirror is stored while being held at an angle set by the driver. However, when the vehicle is stored outdoors, water droplets such as raindrops may adhere to the mirror surface. As a result, it is difficult to check the rear while driving, and the driver may have to take the trouble of wiping off the water droplets on the mirror surface with a towel when starting or while driving. In particular, it is difficult to wipe off the side mirror surface on the passenger side from the driver's seat. Therefore, a method of reducing the adhesion of raindrops by applying a hydrophilic coating to the mirror surface has been considered, but this requires work and costs, and the effect is only temporary.

[0005] The present invention is devised to solve the above-mentioned problems, and aims to provide a vehicle device that can reduce the adhesion of raindrops by tilting the angle of the mirror surface of the side mirror when parking the vehicle, such as when the ignition is turned off, without increasing costs or effort. [Means for solving the problem]

[0006] In order to achieve the above object, a vehicle device according to the present invention includes a variable means for changing an angle of a mirror surface of a mirror housing provided on the outside of a vehicle so as to face an opening side, a projection extending in a direction opposite to the opening direction of the opening of the mirror housing is provided on an upper portion or on the left and right sides of the mirror surface; The variable means is characterized in that when the vehicle enters a parking start state, the angle of the mirror surface is tilted to an angle at which the upper part or the left and right sides of the mirror surface protrude from the opening of the mirror housing, and when the vehicle enters an operation start state, the angle of the mirror surface that was changed when the vehicle entered a parking start state is returned to the angle before the change. Effect of the Invention

[0007] According to the present invention, a vehicle device can be provided that can reduce the adhesion of raindrops by tilting the angle of the mirror surface of the side mirror when parking the vehicle, such as when the ignition is turned off. [Brief description of the drawings]

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. However, the present invention is not limited to or restricted by the following description.

[0010] A vehicle according to an embodiment of the present invention is equipped with a vehicle device 2 that can tilt the angle of the mirror surface of the side mirror to an angle that reduces raindrop adhesion when parking the vehicle, such as when the ignition is turned off. The vehicle device 2 includes a mirror position sensor 31 that detects the angle (position) of a mirror section 42 provided in a mirror unit 30 equipped in the vehicle, and a mirror controller 20 that stores the angle of the mirror section 42 detected by the mirror position sensor 31 and controls the angle of the mirror section 42. The vehicle device 2 changes the angle of the mirror section 42 (mirror surface 42a) when parking the vehicle, such as when the ignition is turned off, and controls the angle of the mirror section 42, which was changed when parking, to return it to the angle before the change when the user operates the vehicle, such as when the ignition is turned on.

[0011] 1 is a schematic diagram showing a configuration of a vehicle device 2 according to an embodiment of the present invention. The vehicle device 2 includes a BODY_ECU 10, a mirror controller 20, and a mirror unit 30. The internal structure of the mirror unit 30 includes a mirror position sensor 31, a retraction motor 32, a left / right angle adjustment motor 33 for a mirror portion 42 of the mirror unit 30, and a top / bottom angle adjustment motor 34.

[0012] FIG. 2 is a schematic side cross-sectional view of the mirror unit 30. The mirror unit 30 is of an electrically retractable type, and includes a mirror housing 46 as an outer case thereof, a mirror section 42, and an internal structure including a known angle adjustment mechanism for adjusting the angle of the mirror section 42, an electrically retractable mechanism, and a mirror position sensor 31. The mirror section 42 is for a user sitting in the driver's seat to view the surroundings of the vehicle by using a mirror surface 42a of the mirror section 42, and is connected to a rotation shaft 48 provided in the mirror housing 46. The mirror housing 46 has an opening 50, and the mirror section 42 is provided so that its mirror surface 42a faces the opening 50 side. In this embodiment, the mirror unit 30 is a side mirror provided on the outside of the vehicle, and the description will be given assuming that the direction in which the opening 50 is opened (the rear side of the vehicle when the mirror unit is open) is the rear, and the opposite side is the front.

[0013] The angle adjustment mechanism in the mirror unit 30 includes a rotating shaft 48, a left / right angle adjustment motor 33, and a vertical angle adjustment motor 34 shown in FIG. 1. The rotating shaft 48 is operatively connected to the left / right angle adjustment motor 33 and the vertical angle adjustment motor 34. This allows the angle of the mirror section 42 to be adjusted in the left / right direction or the vertical direction. The electric storage mechanism includes the storage motor 32 shown in FIG. 1, and the mirror unit 30 can be stored / opened by connecting the storage motor 32 to a rotating shaft (not shown) connected to the mirror housing 46. Storage may be, for example, by closing the mirror surface 42a of the mirror section 42 laterally relative to the vehicle so that it fits along the vehicle body, or by twisting the mirror unit 30.

[0014] As shown in FIG. 2, a protrusion 44 is provided on the upper part of the mirror part 42. The protrusion 44 is provided so as to extend to the front side (the rear side of the vehicle when the mirror unit is open) and the back side (the front side of the vehicle when the mirror unit is open) of the mirror surface 42a. The front side protrusion 44a has a function of preventing water droplets such as raindrops from adhering to the mirror surface 42a like an umbrella, and the back side protrusion 44b has a waterproof and dustproof function for the inside of the mirror unit 30 when the mirror surface 42a of the mirror part 42 is facing downward. The protrusion 44 may be formed integrally with the mirror part 42, for example, or may be joined by providing a bracket or the like on the upper part of the mirror part 42. The length of the protrusion 44 can be changed as appropriate. For example, the protrusion 44 may be formed only on the front side, or the protrusion 44a or the back side protrusion 44b may be formed so as to be longer around the upper part of the mirror part 42, or both may be the same length.

[0015] The BODY_ECU 10 is composed of a microcomputer including a CPU, RAM (volatile memory), ROM (non-volatile memory), and I / O, and controls door lock and door unlock, and controls the storage motor 32 to store / open the mirror unit 30 (so-called opening and closing operations). The door lock and door unlock are controlled based on operation information sent via a communication device (not shown) by the key 12. The operation information of the key 12 may be, for example, information from a portable device (such as a remote control), information in which a user operates a part of the vehicle (such as a switch provided on a door handle), or information in which the door lock (also called key lock / key unlock) is released when the user approaches the vehicle.

[0016] When the IG_SW 16 provided at the driver's seat is operated to turn the IG off, the BODY_ECU 10 transmits an IG off signal to the mirror controller 20. The BODY_ECU 10 also performs door locking based on the operation information of the key 12. When the door is locked, the BODY_ECU 10 controls the retraction motor 32 to retract the mirror unit 30. When the mirror position sensor 31 detects that the mirror unit 30 is in the retracted position or has begun to move from the open position, the BODY_ECU 10 transmits a retraction signal for the mirror unit 30 to the mirror controller 20.

[0017] When the IG_SW 16 is operated to turn on the IG, the BODY_ECU 10 transmits an IG ON signal to the mirror controller 20 and controls the retraction motor 32 to open the mirror unit 30. That is, the mirror unit 30 is returned to a predetermined position before retraction. In addition, when the mirror position sensor 31 detects that the mirror unit 30 is in the open position or has begun to move from the retracted position, the BODY_ECU 10 transmits an open signal for the mirror unit 30 to the mirror controller 20. Note that the transmission of the IG ON / OFF signal from the BODY_ECU 10 to the mirror controller 20 may be transmitted simultaneously with the retraction / open signal for the mirror unit 30.

[0018] Based on the signal transmitted from the BODY_ECU 10 and the detection signal from the mirror position sensor 31, the mirror controller 20 determines whether the vehicle is in a parking (stopped) start state and whether the vehicle is in an operation start state, and then controls the left / right angle adjustment motor 33 and the up / down angle adjustment motor 34 to change the angle of the mirror section 42.

[0019] The parking start state is a state in which the user is about to park the vehicle or can recognize that the vehicle has been parked, and includes, for example, a case in which the IG_SW 16 is operated to turn off the IG, a case in which the door is locked (key locked), or a case in which the mirror unit 30 is stored. For example, the parking start state may be determined by detecting an on / off operation signal of a courtesy switch (not shown) provided on the door 14 by opening and closing the door 14 in order for the user to get off the vehicle, and then locking the door. The operation start state is a state in which the user is about to operate the vehicle or can recognize that the vehicle has been operated, and includes, for example, a case in which the IG_SW 16 is operated to turn on the IG, a case in which the door is unlocked (key locked), or a case in which the mirror unit 30 is opened. The storage / open signal of the mirror unit 30 may be input to the mirror controller 20 via the BODY_ECU 10, or may be input directly to the mirror controller 20 without passing through the BODY_ECU 10.

[0020] The mirror controller 20 stores the angle of the mirror section 42 detected by the mirror position sensor 31. The angle of the mirror section 42 can be adjusted to a desired angle by the user by operating a mirror adjustment button (mirror switch) (not shown) or the like. When the user performs a mirror adjustment operation, the mirror controller 20 controls the left / right angle adjustment motor 33 and the up / down angle adjustment motor 34 to adjust (change) the angle of the mirror section 42. The mirror controller 20 stores the adjusted (changed) angle of the mirror section 42 detected by the mirror position sensor 31.

[0021] The mirror position sensor 31 is a position detection sensor for detecting the position of the mirror unit 30 in the storage (opening / closing) direction and the angular position of the mirror portion 42. Position information detected by the mirror position sensor 31 is input to the BODY_ECU 10 and the mirror controller 20 as a detection signal.

[0022] The changeable angle of the mirror section 42 in this embodiment will be described with reference to FIG. 3. A to C in FIG. 3 are examples of states of the mirror section 42 provided with the protrusion 44 shown in FIG. 2 at the changeable angle, shown on the same drawing. The state shown by A is a state in which the mirror section 42 is tilted to an angle at which the upper part of the mirror section 42 does not protrude from the opening 50 of the mirror housing 46. The state shown by B is a state in which the mirror section 42 is tilted so that the mirror surface 42a faces downward, and is at an angle at which the upper part of the mirror section 42 protrudes from the opening 50 of the mirror housing 46. The state shown by C is a state in which the mirror section 42 is tilted so that the mirror surface 42a faces upward, and the upper part of the mirror section 42 is recessed into the mirror housing 46.

[0023] Here, the angle of the mirror (mirror surface) in the conventional side mirror could only be adjusted to an angle where the upper part of the mirror part 42 does not protrude from the opening 50 of the mirror housing 46, for example, as shown in the state A in FIG. 3. In addition, when the vehicle is parked, the angle of the mirror surface is not changed from the state when the vehicle is traveling. However, with the normal adjustable angle of the mirror surface or the angle of the mirror surface when the vehicle is traveling, there is a risk that raindrops will adhere to the mirror surface when the vehicle is stored outdoors. Therefore, the vehicle device 2 in this embodiment is capable of changing the angle of the mirror part 42 when the vehicle is in the parking start state, and can also tilt the mirror part 42 to an angle where the upper part of the mirror part 42 protrudes from the opening 50 of the mirror housing 46, as shown in the state B in FIG. 3, thereby reducing the adhesion of raindrops to the mirror surface 42a.

[0024] In addition, since the protrusion 44 is provided on the upper part of the mirror part 42 in this embodiment, adhesion of raindrops to the mirror surface 42a can be further reduced, and even when the upper part of the mirror part 42 protrudes from the opening 50 of the mirror housing 46 as shown in B of FIG. 3, the mirror part 42 has a waterproof and dustproof effect on the internal structure of the mirror unit 30. The range of angles at which the mirror part 42 can be tilted may be set to a range in which the mirror part 42 does not interfere with the built-in part (internal structure) of the mirror unit 30. In addition, when the protrusion 44 is provided, the range may be set to a range in which the rear side protrusion 44b does not interfere with the built-in part (internal structure) of the mirror unit 30 when the mirror surface 42a is facing upward and the upper part of the mirror part 42 is inserted deep into the mirror housing 46 as shown in A of FIG. 3.

[0025] Fig. 4 is a flowchart showing an example of a process (operation) for storing the angle position of the mirror unit 42 in the vehicle device 2. The operation of the vehicle device 2 in the present invention will be described with reference to Fig. 4, but the present invention is not limited to this.

[0026] 4, in step S1, it is determined whether the angle of the mirror unit 42 (mirror surface 42a) has been adjusted (changed) by the user. If it is determined that the angle of the mirror unit 42 has not been adjusted (step S1, NO), the position storage process ends. On the other hand, if it is determined that the angle of the mirror unit 42 has been adjusted (step S1, YES), the process proceeds to step S3.

[0027] In step S3, the up-down and left-right angles of the mirror section 42 adjusted in step S1 are detected by the mirror position sensor 31. When the angular position of the mirror section 42 is detected by the mirror position sensor 31, the process proceeds to step S5, and the mirror controller 20 stores the angular position of the mirror section 42 detected by the mirror position sensor 31 in step S3 (user-set mirror surface position), and the position storage process ends. The position storage process is repeatedly executed in a state in which the angular position of the mirror section 42 can be adjusted, for example, when the IG is turned on and the mirror unit 30 is open. Note that the position storage process may be executed when the mirror surface can be adjusted in the IG off state, or may be adjustable when the mirror unit 30 is not open and stored.

[0028] Fig. 5 is a flowchart showing an example of a mirror surface control process (operation) in the vehicle device 2. The operation of the vehicle device 2 in the present invention will be described with reference to Fig. 5, but the present invention is not limited to this.

[0029] In the mirror surface control process shown in FIG. 5, in step S11, it is determined whether or not the IG-OFF (OFF) operation is performed by the IG_SW 16. If it is not determined that the IG-OFF operation is performed (step S11, NO), the mirror surface control process is terminated. On the other hand, after it is determined that the IG-OFF operation is performed (step S11, YES), a signal of the ON / OFF operation of the courtesy SW (switch) is detected (step S13), and then when the door is locked (key lock) (step S15), it is determined that the door is locked after the user gets out of the vehicle and the vehicle is in a parking start state. Next, in step S17, the BODY_ECU 10 stores the mirror unit 30 and transmits a storage signal of the mirror unit 30 to the mirror controller 20, and proceeds to step 19.

[0030] In step S19, the angle of the mirror section 42 (mirror surface 42a) is controlled to be further downward than the current angle, and the process proceeds to step S21. That is, in step S19, the mirror controller 20 determines that the vehicle is in the parking start state because the IG off signal and the storage signal for the mirror unit 30 are transmitted from the BODY_ECU 10 in the above-mentioned steps S11 to S17, and tilts the angle of the mirror surface 42a of the mirror section 42 to an angle at which raindrops are less likely to adhere.

[0031] In step S21, it is determined whether or not the IG-ON (ON) operation has been performed by the IG_SW 16. If it is not determined that the IG-ON operation has been performed (step S21, NO), the process returns to step S21, and step S21 is repeated until it is determined that the IG-ON operation has been performed.

[0032] In step S21, when it is determined that the IG ON operation has been performed (step S21, YES), the process proceeds to step S23, where the BODY_ECU 10 opens the mirror unit 30 and transmits an open signal for the mirror unit 30 to the mirror controller 20, and then the process proceeds to step S25.

[0033] In step S25, the mirror controller 20 controls the angle of the mirror section 42 to return to the angle position stored in the mirror controller 20 by the position storage process of Fig. 4. That is, in step S25, the mirror controller 20 determines that the vehicle is in the operation start state because the IG on signal and the mirror unit 30 open signal are transmitted from the BODY_ECU 10 by the above-mentioned steps S21 to S23, and returns the angle of the mirror section 42 to the angle before the mirror surface 42a was turned downward in step S19 (user-set mirror surface position), and ends the mirror surface control process. Note that if the angle of the mirror section 42 has not been adjusted by the user from the initial setting state of the vehicle, the initial value may be stored in the mirror controller 20.

[0034] As described above, according to the vehicle device 2 of the present invention, the angle of the mirror portion 42 of the mirror unit 30 can be tilted when parking the vehicle, such as when the ignition is turned off, without increasing costs or labor. As a result, it is possible to reduce adhesion of raindrops to the mirror surface 42a even in a situation where there is a risk of raindrops adhering.

[0035] In the above embodiment, in step S19 of Fig. 5, an example has been described in which an IG off signal and a storage signal for the mirror unit 30 are transmitted from the BODY_ECU 10 in steps S11 to S17, so that it is determined that the vehicle is in the parking start state, and the angle of the mirror unit 42 is controlled to be further downward than the current angle. However, the present invention is not limited to this. For example, if the user is trying to park the vehicle or can recognize that the vehicle has been parked, it may be determined that the vehicle is in the parking start state, and the angle of the mirror unit 42 (mirror surface 42a) may be controlled to be downward when, for example, the IG_SW 16 is operated to turn off the IG, the door is locked (key locked), or the mirror unit 30 is stored. That is, the angle of the mirror unit 42 may be controlled to be downward when the mirror unit 30 is not stored.

[0036] In the above embodiment, in step S25 in Fig. 5, an IG on signal and an open signal of the mirror unit 30 are transmitted from the BODY_ECU 10 in steps S21 to S23, so that it is determined that the vehicle is in the operation start state, and the angle of the mirror unit 42 is returned to the angle position stored in the mirror controller 20 by the position storage process in Fig. 4. However, the present invention is not limited to this. For example, if the user is about to operate the vehicle or can recognize that the vehicle has been operated, it may be determined that the vehicle is in the operation start state, and the angle of the mirror unit 42 may be returned to the original angle position when, for example, the IG_SW 16 is operated to turn on the IG, the door is unlocked (key is unlocked), or the mirror unit 30 is opened. That is, the angle of the mirror unit 42 may be returned to the original angle position when the mirror unit 30 is not stored.

[0037] 5 in the above embodiment has been described as being performed when the mirror unit 30 is stored by the BODY_ECU 10 in step S17, i.e., simultaneously with the storage of the mirror unit 30, but the present invention is not limited to this and may be performed after the mirror unit 30 is stored or before the mirror unit 30 is stored. Also, the present invention has been described as being performed when the mirror unit 30 is opened by the BODY_ECU 10 in step S23, i.e., simultaneously with the opening of the mirror unit 30, but the present invention is not limited to this and may be performed after the mirror unit 30 is opened or before the mirror unit 30 is opened.

[0038] In the above embodiment, the mirror unit 30 is stored when the door is locked and opened when the IG is turned on, but the present invention is not limited to this. For example, the mirror unit 30 may be stored when the IG is turned off, or may be opened when the door is unlocked (key lock is released). The mirror unit 30 may also be capable of being stored / opened by the user's operation of a button (mirror switch) or the like.

[0039] In the above embodiment, the angle of the mirror unit 42 may be different between an angle controllable by the mirror controller 20 in the parking start state and an angle controllable by the user, or the user may be able to control the angle of the mirror unit 42 up to an angle controllable by the mirror controller 20 in the parking start state. In that case, in step S19 of Fig. 5, if the angle of the mirror unit 42 is already at the maximum angle at which it can be angled downward, for example, by a user operation, the angle of the mirror unit 42 is not controlled to be further angled downward in step S19, and therefore the mirror position is not returned in the subsequent step S25, and deterioration due to wear of the motor can be prevented.

[0040] In the above embodiment, an example was described in which the upper part of the mirror portion 42 protrudes from the opening 50 of the mirror housing 46, as in the state shown in B of Figure 3, but this is not limited thereto. The control to tilt the mirror portion 42 downward in step 19 of Figure 5 may be within the existing tiltable range (for example, the angular position of the mirror portion 42 shown in A of Figure 3).

[0041] In the above embodiment, an example of controlling the mirror section 42 to face downward in step S19 in Fig. 5 has been described, but the present invention is not limited to this. In addition to the control to face downward, the mirror section 42 may be controlled in the left-right direction by the left-right angle adjustment motor 33, for example, so that the mirror surface 42a of the mirror section 42 is brought closer to the vehicle side. In this case, for example, the left and right side surfaces of the mirror section 42 may be provided with protrusions 44 so that the mirror section 42 protrudes from the mirror housing 46, or may not protrude from the mirror housing 46 within the existing tiltable range. This can reduce adhesion of raindrops to the mirror surface 42a, even if there is rain and wind accompanied by strong winds blowing from the side of the mirror unit 30.

[0042] In the above embodiment, the process of controlling mirror section 42 to face downward in step S19 of FIG. 5 may be performed based on weather information. For example, when it is determined that the vehicle is in a parking start state, control may be performed if rain is forecast in the weather information for a predetermined period (hour) ahead, and if strong winds are forecast, mirror section 42 may also be controlled to face sideways.

[0043] 5 in the above embodiment, the process of controlling the mirror unit 42 to face downward may be performed based on information acquired from a camera, a sensor, or the like mounted on the vehicle, and for example, when it is determined that the vehicle is in a parking start state, if it is detected whether the vehicle is surrounded by walls or there is a roof on the upper part of the vehicle, the process of controlling the mirror unit 42 to face downward may not be performed. This makes it possible to prevent deterioration due to wear and tear of the motor.

[0044] In the above embodiment, an example in which the protrusion 44 is provided on the mirror portion 42 has been described, but in addition to this, a drip channel may be formed on the upper portion of the protrusion 44. That is, a groove may be provided on the upper surface portion of the protrusion 44 in the left-right direction of the mirror portion 42 so that rainwater flows down to the left and right outer sides of the mirror portion 42 through the groove. In addition, the upper surface portion of the protrusion 44 may be formed into a gently convex curved shape so that rainwater can easily flow down in the left-right direction of the mirror portion 42.

[0045] In the above embodiment, the mirror unit 42, which is the object controlled to be tilted downward in step S19 of FIG. 5, is a side mirror. However, the present invention is not limited to this, and can be applied to any mirror provided on the outside of the vehicle. The present invention can also be applied to objects that may be affected by raindrops, such as cameras and sensors provided on the outside of the vehicle, instead of the mirror surface of the present invention, and can prevent deterioration of visibility and malfunction due to raindrops adhering to the sensor. In this case, the tilting range may be within the existing tilting range, and the protrusion 44 may not be provided. At least, by tilting the object such as the mirror surface downward, it is possible to reduce raindrops adhering to the mirror surface.

[0046] It should be noted that the embodiments disclosed herein are illustrative and not restrictive in all respects. The scope of the present invention is defined by the claims, not the above description, and is intended to include all modifications within the meaning and scope of the claims.
