[62] (First embodiment). A first embodiment related to a camera comprises an optical sensor according to the present invention, which is described below with reference to FIG. IA -5.
[63] As shown in FIG. 1A and 1B, an optical sensor unit I (an optical sensor device for onboard mounting of the present invention) comprises a camera cover 2 (an optical sensor cover for board mounting of the present invention) and a camera 3. The camera 3 is mounted on the camera cover 2 on a demountable sweetener. . In the camera 3, a lens 5 is placed on a front side (a left side in FIG. 1B) of a housing 4, and a power supply line (shown in E) and an image signal output line (shown in E) are drawn from a rear side (a right side in FIG. IB) of the housing 4. The power supply cord is used to supply power to the camera 3. The image signal output line is used to output an image signal. The lens 5 is a fisheye lens and has a curved surface 5a which can take a wide angle image.
[64] In the camera cover 2 there is a holder 7 for holding the camera 3 placed in a housing 6 and an opening 8 is placed on a rear side of the housing 6. As shown in FIG. 2 for the camera 3 mounted on the camera cover 2 through the opening 8 and detachable from the camera cover 2 through the opening 8. In the camera cover 2 a washer nozzle 9 is placed above the holder 7. The washer nozzle 9 has an "L" shape.
[65] In this case, when the motor 16 is running, a washer fluid is introduced into the washer fluid tank 15 and the washer nozzle 9 is supplied through the pipe 10. The washer fluid is supplied to the washer nozzle 9 and is hydraulically spread from the spreader opening 1 1 on the inlet surface 5a of the camera. can be spread on different sweet. For example, the washer fluid may be spread on the surface 5a in the form of a mist. In another example, a moderate amount of the washer liquid can be applied to the surface 5a in the form of butter particles which are not finer than the mist. In a further example, a predetermined amount of the washer fluid may be applied to the surface 5a in the form of one block at a time. It should be noted that the washer fluid tank 15 is installed in a typical engine compartment of the vehicle body 12.
[66] A liquid crystal display device 17 (a reporting means of the present invention) is placed in a hand compartment. Near the output 11 the image signal from the camera 3, the liquid crystal display device 17 receives an image corresponding to the image signal by decoding the image signal. The controller 14 detects whether the image contains dirt or fog by analyzing the image displayed on the liquid crystal display device 17 (for example, by determining whether the pixelius is large or small).
[67] A coil switch 18 is operable by a user. When a user operates the coil switch 18, the coil switch 18 outputs an operation detection signal to the controller 14. When the controller 14 receives the operation detection signal output from the coil switch 18, the controller 14 outputs a control command signal to the motor 16, thereby driving the motor 16. For example, the control command signal output from the controller 14 to the motor 16 is a level signal, and the washer operation of the washer nozzle 9 is performed only for a period of time when the level signal is ON (High level). The coil switch 18 may be a mechanical switch or a touch switch offset on the liquid crystal display device 17.
[68] An in-vehicle integrated LAN interface 19 receives a gear position signal indicating a position of a gear on the vehicle, an ACC signal indicating an ON / OFF state of an ACC switch (accessory switch), and an Ig signal indicating a an ON / OFF state of an Ig switch (ignition switch) from different types of ECUs through a vehicle integrated LAN 22. Then the vehicle integrated LAN interface 19 outputs the received different types of signals to the controller 14. When the controller 14 receives different types of signals output from the vehicle integrated LAN interface 19, the controller 14 analyzes the different types of signals received, thereby detecting the position of the switch, the ON / OFF state of the ACC switch and the ON / OFF state of the ICE switch.
[69] Next, an operation of the above configuration will be described below with reference to FIG. 5. 12
[70] In a current ON state (in a driving state of the optical sensor unit 1), the controller 14 determines if the coil switch 18 is actuated (step S1). When the controller 14 receives the operation detection signal output from the coil switch 18 and determines that the coil switch 18 is actuated ("YES" at step S1), the controller 14 outputs the drive command signal to the motor 16 to drive the motor 16; whereby the rinsing operation of the rinsing nozzle 9 is performed (step S2). That is, the washer fluid stored in the washer fluid tank 15 is supplied to the washer nozzle 9 and spread from the spreader opening 11 on the lens surface 5a of the lens 5 of the camera 3. In this case, the controller 14 can continue the washer operation of the washer nozzle 9 only for a predetermined period of time. . Alternatively, the regulator 14 can continue the washer operation of the washer nozzle 9 only while a user is operating (for example, pressing) the washer switch 18.
[71] As described above according to the first embodiment, the camera guard 2 is mountable on and removable from the camera 3 provided with the rinsing nozzle 9 for spreading the rinsing liquid supplied from the rinsing liquid tank 15 on the lens surface 5a of the lens 5 of the camera 3 for rinsing the lens surface 5a. In such an approach, a conventional compressed air generating unit is required to disperse compressed air so that the cost and size can be reduced. A promotional object attached to the lens surface 5a is conveniently removed so that the camera 2 can function properly. Furthermore, since the camera cover 2 is mountable on and detachable from the camera 3, these can be independent of each other and easily replaced.
[72] (Second embodiment). A second embodiment of the present invention is described below with reference to FIG. ó and 7. The second embodiment differs from the first embodiment in the following points. In the first embodiment, the washer operation of the washer nozzle 9 is triggered when the washer switch 18 is operated by a user. That is to say, the washer operation of the washer nozzle 9 is performed manually. In the second embodiment, the operating conditions include detecting the fact that the gear has switched to a reverse light (detecting the fact that a gear of a vehicle is in a predetermined position of the present invention), detecting the fact that the IG switch is switched from an AV state to a P state (detecting the fact that activation of a vehicle is started in the present invention), and detecting the fact that the Ig switch is switched from the P state to the AV state (detecting the fact that activation of a vehicle is completed by the present invention). The rinsing operation of the rinsing nozzle 9 is triggered when one of the working conditions is met or when the image contains dirt. That is, the washer operation of the washer nozzle 9 is performed automatically. A regulator 31 according to the second embodiment has a smoking function.
[73] In FIG. 7, in the current ON state (in the driving state of the optical sensor unit 1), the controller 31 determines if any of the operating conditions are met (step s1 1) and determines if the image contains dirt (step S12). Then, if the controller 31 determines that any of the operating conditions are met, that is, sucks, determines that the switch is switched to reverse, the ICE switch is switched from the AV state to the ON state, or the Ig switch is switched from the P state to OFF mode ("YES" at step S1 1), or if the controller 31 determines that the image contains dirt ("YES" at step S12), the controller 31 runs the motor 16, thereby performing washer operation of the washer nozzle 9 during a predetermined time period (step S13).
[74] Thereafter, the controller 31 (addition with “1”) increments a coil number counter (step S14) and determines if a value of the increased coil number counter is less than a predetermined number (step S15). If the controller 31 determines that the value of the increased coil number counter is less than the predetermined number ("YES" at step S15), the controller 31 returns to step S12 and repeats subsequent steps at step S12. If the controller 31, on the other hand, determines that the value of the increased the coil number counter is equal to or greater than the predetermined number ("NO" at step S15), the controller 31 causes the liquid crystal display device 17 to display an error on the screen indicating that the coil operation of the coil nozzle 9 has been performed the predetermined number of times (step S16) . Then the controller 31 resets the value of the coil number counter (step S17) and ends the series of procedures.
[75] If the controller 31 determines that the image does not contain dirt (dirt is removed as a result of the washer operation of the washer nozzle 9) ("NO" at step S12), the controller 31 resets the value of the washer number counter (step S18), then returns to step S1 1 and repeats subsequent steps at step S1 1.
[76] As described above, according to the second embodiment, the lens surface 5a of the lens 5 of the camera 3 can be automatically flushed whenever it is detected that the gear of the motor is switched to reverse position, the ICE switch is switched from the AV state to the P1 state, The Ig switch is switched from the ON state to the OFF state or the picture contains dirt. Furthermore, the error is displayed on the screen when the coil number counter becomes equal to or greater than the predetermined number. Alternatively, if a rinsing time measurement function is included, the error may be displayed on the screen when the rinsing time reaches a predetermined time.
[77] The embodiments described above can be modified or expanded as follows.
[78] The optical sensor is not limited to the camera 3 and may be a sensor, such as a laser, which has a lens and optically measures a physical quantity.
[79] In the embodiments in the case where the value of the coil number counter is equal to e | er greater than the predetermined number, the error message is displayed on the floating crystal display device I7. Alternatively, in such a case, an ambient fault is prepared from a loudspeaker, or a vibration or a static electricity can be generated from a seat or a pull handle by a static electricity or a vibration generator mounted on the seat or the pull handle. Alternatively, these can be used in combination with each other. That is to say, reporting can be performed through any of the senses, hearing or senses.
[80] The configuration shown in FIG. 5 in which the washer operation of the washer nozzle 9 is performed monuely, can be used in combination with the configuration shown in FIG. 7, in which the spoiler operation of the spoiler nozzle 9 is performed automatically.
[81] As shown in FIG. 8A and 8B, a water-repellent treatment may be applied to the surface 5a of the camera 5 for the lens 3 so that the liner can be covered with a water-repellent ion 41. Alternatively, a hydrophilic treatment, a photocatalytic treatment or a primer treatment may be applied to the surface of the camera. covered with a hydrophilic Ioger, a photocatalytic Ioger or a primer layer. In such an approach it is possible to prevent the foreign objects such as water and dirt from sticking to the surface of the surface.
[82] As shown in FIG. 9A and 9B, a housing S2 of a camera cover S1 may be provided with a window washer nozzle S3 arranged parallel to the washer nozzle 9. The washer liquid grounded in the washer fluid tank IS may be supplied to the window washer nozzle S3 through a pipe S4 of the windshield washer spreader opening SS on a window.
[83] As shown in Figs. 10A and 10B, a housing 62 of a camera cover 61 may be provided with a bowl 63 and a tube 64. Once the washer liquid has spread from the spreader opening 11 of the washer nozzle 9 on the lens surface 5a of the lens 5 of the camera 3, the bowl 63 may catch the washer liquid dripping from the lens surface 5a, and the washer fluid that has been trapped by the stack 63 can be emptied through the tube 64. In such an approach, it is possible to prevent the window from becoming dirty through the washer fluid dripping from the lens surface 5a. Alternatively, the bowl may have a hole and the washer liquid dripping from the lens surface 5a may be supplied to the window through the hole so that the window can be flushed.
[84] As shown in FIG. 11A and 11B, a housing 72 of a camera guard 71 may be provided with a hood 73. The hood 73 has a projection for protecting the lens surface 51 from above. With such an approach, it is possible to prevent the foreign objects such as water and dirt (especially raindrops) coming from above, from sticking to the lens surface 5a.
[85] As shown in FIG. 12A and 12B, a housing 82 of a camera guard 81 may be provided with a projection 83 located at a position (directly below the lens 5) adjacent a bottom edge of the lens surface 5a of the lens 5 of the camera 3. In such an approach even if water collected at the bottom edge of the lens surface 5a, the water collected at the bottom edge of the lens surface 5a comes into contact with the projection 83, the water being led under the lens surface 5a and thus removed. 17
[86] The position in which the water collects at the bottom edge of the lens surface 5a varies depending on the curvature and diameter of the lens 5. For this reason shown in FIG. 13A and 13B, a housing 92 of a camera guard 91 may be provided with a projection 93. The projection 93 may be located at the position adjacent the bottom edge of the lens surface 5a of the lens 5 of the camera 3 and moved up and down along a slit 94. For example, the diameter of the lens 5 is large, the projection 93 for a displacement can be reduced, and when the diameter of the lens 5 is small, the projection 93 can be increased for a displacement. By allowing the projection 93 to be moved up and down in this manner, the projection may suitably come into contact with the water regardless of the bend or diameter of the lens 5. For example, the projection 93 may be provided with a male screw part and the gap 94 may be provided with a male screw part.
[87] As shown in FIG. 14A and 14B, a housing 102 of a camera cover 101 may be provided with a transparent protective glass 103. The protective glass 103 may be located on the front of the housing 102 facing the lens 5 of the camera 3. The washer fluid supplied from the washer fluid tank 15 to the washer nozzle 9 through the tube Can be spread from the spreader opening 11 on a glass surface 103a of the protective glass 103.
[88] As shown in FIG. 15A and 15B, a water-repellent treatment can be applied to the glass surface 103a of the protective glass 103 so that the glass surface 103a can be covered 18 with a water-repellent layer 1 1 1. Alternatively, a hydrophilic treatment, a photocatalytic treatment or a bottom paint treatment may be applied to the glass surface 103a so that the glass surface 103a can be covered with a hydrophilic layer, a photocatalytic layer or a bottom paint layer. With such an approach, it is possible to prevent the foreign objects such as water and dirt from sticking to the glass surface 103a. Furthermore, even if the foreign objects such as water and dirt are attached to the glass surface 103a, the rinsing operation of the rinsing nozzle 9 is performed so that the glass surface 103a can be secretly rinsed.
[89] As shown in FIG. 16A and 10B, a housing 122 of a camera guard 121 may be provided with a drying mechanism 125 (a drying means in the present invention). The drying mechanism 125 includes a windshield wiper 123 for drying the glass surface 103a of the protective glass 103 and a motor 124 for running the windshield wiper 123. The drying mechanism 125 may dry the glass surface 103a of the protective glass 103 during or after the washer liquid has spread on the glass surface 103a of the protective glass 103 1 of such a rinse nozzle 9. With such an approach sweet it is possible to prevent the washer liquid from sticking to the glass surface 103a of the protective glass 103. Alternatively, if the protective glass 103 is not present, a drying mechanism for drying the lens surface 5a of the camera lens 5 be.
[90] As shown in FIG. 17A and 17B, a housing 132 of a camera guard 131 may be provided with a rotating mechanism 135 (a rotating means in the present invention). The rotating mechanism 135 includes a sealed bearing 133 and a motor 134 for causing the protective glass 103 to rotate. The rotating mechanism 135 can cause the protective glass 103 to rotate during or after the washer liquid has spread from the spreading opening 11 of the washer nozzle 9 on the glass surface 103a of the protective glass 103. .
[91] If the protective glass is placed for 103 years, dies as in a door mirror, a person in the vehicle can reach it, it being preferable to take measures to prevent the person from reaching it. Due to this rinse, the rotating mechanism 135 may be configured to rotate the protective glass 103 on the condition that the window is closed. With such an approach, it is possible to prevent a problem caused by the person touching the protective glass 103 which rotates. In this case, it is not always necessary for the window to be closed. It does not matter if the window is slightly open, unless the window is closed to a position so that it can prevent a user from moving the protective glass 103 by leaning out of the window. In this case, air can be let in through the window. The position to which the window should be closed can be determined based on a relationship between where the protective glass 103 is placed in the vehicle and how much a user can lean out of the window. 20
[92] As shown in FIG. 18A and 18B, a housing 142 of a camera guard 141 may be provided with a vibrating mechanism 145 (an ultrasonic vibrating means or a subsonic vibrating means in the present invention).
[93] As shown in FIG. 19A and 19B, a housing 152 of a camera guard 151 may be provided with an air diffusion mechanism 156 (an air diffuser in the present invention). The air spreading mechanism 156 includes an air nozzle 153, a tube 154 and an air pump 155 for spreading air on the glass surface 103a of the protective glass 103. The air spreading mechanism 156 may spray air on the glass surface 103a of the protective glass 103 during or after the rinsing liquid has spread from the spray nozzle. the washer nozzle 9 on the glass surface 103a of the protective glass 103. In such an approach, it is possible to prevent the washer liquid from remaining stuck on the glass surface 103a of the protective glass 103.
[94] The drying mechanism 125 explained in FIG. 16A and 16B, the rotating mechanism 135 explained in FIG. 17A and 17B, the vibration mechanism 145 explained in FIG. 18A and 18B and the air spreading mechanism 156 explained in FIG. 19A and 19B may be configured to operate in accordance with the operating status of a vehicle windshield wiper. The drying mechanism 125, the rotating mechanism 135, the vibration mechanism 145 and the air diffusion mechanism 156 can operate for a period of time when the vehicle windshield wipers are operating. In such an approach, it is possible to prevent raindrops from sticking to the surface 5a 21 or the glass surface 103a.
