Description of the Related Art In recent years, it has been widely used to provide an in-vehicle sensor such as an in-vehicle camera at a front portion or a rear portion of a vehicle and use an image or the like captured by the in-vehicle sensor. Since there is a possibility that foreign matter such as water droplets or mud may adhere to the lens surface of such an in-vehicle sensor, an in-vehicle sensor cleaning device that removes foreign matter by injecting a fluid from the sensor cleaning nozzle toward the lens surface has been proposed. Have been. Such an in-vehicle sensor cleaning apparatus removes foreign matter by injecting a cleaning liquid toward a lens surface of an in-vehicle sensor (for example, see Patent Document 1), or injects air toward a lens surface of an in-vehicle sensor. An apparatus that removes foreign matter by using a method (for example, see Patent Document 2) has been proposed.

JP 2001-171491 A JP 2009-83730 A

  By the way, when the foreign matter adhering to the lens surface is a water droplet, the foreign matter can be removed by injecting only air. On the other hand, when the foreign matter adhering to the lens surface is mud or the like, it cannot be removed only by air, and a cleaning liquid must be sprayed. Therefore, for example, it is conceivable that the user injects only air or a fluid containing a cleaning liquid as necessary, but in this case, if the operation is complicated, the user may be confused at the time of operation. There is a risk of doing so.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide an on-vehicle sensor cleaning apparatus that can easily clean a lens surface in a desired mode.

An on-vehicle sensor cleaning device that solves the above-mentioned problems includes a sensor cleaning nozzle for ejecting a fluid toward a lens surface of an on-vehicle sensor mounted on a vehicle to remove foreign matter attached to the lens surface, An air supply unit that supplies air as the fluid to the nozzle, a cleaning liquid supply unit that supplies the cleaning liquid as the fluid to the sensor cleaning nozzle, a control unit that can control the air supply unit and the cleaning liquid supply unit, A single operation switch, wherein the control unit controls the air supply unit to inject only air based on the operation of the operation switch, and the cleaning liquid supply unit to inject cleaning liquid. It is those to switch between the washer mode control for controlling the control unit, a single of said operation switch Based on the work, perform the washer mode control with a preset waiting time expires after the air mode control.

  According to this configuration, a single operation switch is provided, and based on the operation of the operation switch, the control unit controls the air supply unit to inject only air and controls the air supply unit to inject the cleaning liquid. The mode is switched to the washer mode control in which the cleaning liquid supply unit is controlled. Therefore, the user can easily clean the lens surface in a desired mode. That is, for example, when the operation switch is provided separately for each mode, the user needs to consider which operation switch corresponds to each mode, and the user is confused. Accordingly, such confusion during the operation can be suppressed, and the lens surface can be easily cleaned in a desired mode.

  According to this configuration, based on a single operation of the operation switch, the control unit first performs the air mode control, and then performs the washer mode control. For example, first, only air is injected by the air mode control. When the foreign matter such as water droplets on the lens surface is removed, the operation of the operation switch is stopped, whereby the cleaning can be completed without consuming the cleaning liquid. Further, for example, when only air is injected in the air mode control and foreign matter on the lens surface is not removed, the operation switch is continuously operated, and the cleaning liquid is injected in the washer mode control. Foreign matter on the lens surface such as mud that could not be removed can be removed. In this way, a single operation of a single switch allows the user to clean the lens surface satisfactorily without any hesitation, and when the foreign matter can be removed by jetting only air, the cleaning liquid is removed. Consumption can be prevented.

  According to this configuration, the washer mode control is performed when a preset standby time elapses after the air mode control is performed by the control unit based on a single operation of the operation switch. By stopping the operation of the operation switch before the time elapses, the washing can be completed without consuming the washing liquid. That is, for example, if the washer mode control is performed immediately after the air mode control is performed, the timing of stopping the operation of the operation switch is delayed even though the foreign matter can be removed by the injection of only air, which is unnecessary. There is a possibility that the cleaning liquid is consumed in the first step, but this can be prevented.

  In the above-mentioned in-vehicle sensor cleaning device, when the control unit performs the washer mode control, the control unit performs a final air mode control that controls the air supply unit to inject only air regardless of an operation of the operation switch. Is preferred.

  According to this configuration, when the washer mode control is performed, the final air mode control in which the air supply unit is controlled to inject only air is performed by the control unit regardless of the operation of the operation switch. Even if the user does not perform another operation, it is possible to prevent the cleaning liquid from remaining on the lens surface.

  In the above-mentioned in-vehicle sensor cleaning device, the operation switch is provided so as to be operable between an air mode position and a washer mode position that is located beyond the air mode position, and the control unit includes: It is preferable that when operated to the air mode position, the air mode control be performed, and when the operation switch is operated to the washer mode position, the washer mode control be performed.

  According to this configuration, when the operation switch is operated to the air mode position, the air mode control is performed by the control unit, and when the operation switch is operated to the washer mode position located beyond the air mode position, Washer mode control is performed by the control unit. Therefore, the user first operates the operation switch to the air mode position located before the washer mode position, so that only air is injected by the air mode control to remove foreign matter such as water droplets on the lens surface. In this case, by stopping the operation of the operation switch, the cleaning can be completed without consuming the cleaning liquid. Further, for example, when only air is injected by the air mode control and foreign matter on the lens surface is not removed, the user operates the operation switch to the washer mode position that is beyond the air mode position. In addition, the cleaning liquid is sprayed by the washer mode control, so that it is possible to remove foreign matters on the lens surface, such as mud, which cannot be removed by spraying only air. In this way, for example, when the user can first remove foreign matter by jetting only air without losing the order, consumption of the cleaning liquid can be prevented.

  The vehicle-mounted sensor cleaning device, wherein the air supply unit is an air pump that supplies air to the sensor cleaning nozzle by injecting compressed air by opening a flow path after compressing the air when driven to open the flow path. The cleaning liquid supply unit includes a washer pump that supplies a cleaning liquid when driven to supply the cleaning liquid to the sensor cleaning nozzle, and the control unit controls a timing when the air pump drives the washer pump. It is preferable to synchronize with the timing of injecting air.

  According to this configuration, the control unit synchronizes the timing at which the washer pump is driven with the timing at which the air pump injects air. It can be used only when the air with high cleaning performance is injected. Therefore, it is possible to suitably remove foreign matters such as mud on the lens surface while suppressing the consumption of the cleaning liquid.

  With the vehicle-mounted sensor cleaning device of the present invention, the lens surface can be easily cleaned in a desired mode.

Hereinafter, an embodiment of a vehicle will be described with reference to FIGS.
As shown in FIG. 1, a back door 2 is provided behind the vehicle 1, and the back door 2 is provided with a vehicle-mounted camera 5 as a vehicle-mounted sensor.

The in-vehicle camera 5 has a substantially cubic main body 5a in which an image pickup device (not shown) is housed, and a lens 5b as a lens surface provided on one surface of the main body 5a.
For example, when the shift lever SL of the transmission is operated to the reverse position, the in-vehicle camera 5 transmits a captured image behind the vehicle 1 to the display DSP in the vehicle to display the captured image.

  In the back door 2, a first sensor cleaning nozzle 6 serving as a sensor cleaning nozzle for ejecting the supplied air toward the lens 5 b is supplied to a position adjacent to the vehicle-mounted camera 5. A second sensor cleaning nozzle 7 as a sensor cleaning nozzle for injecting a cleaning liquid toward the lens 5b is provided.

  The first sensor cleaning nozzle 6 is connected via a pipe 8 to an air pump AP provided behind the vehicle 1. When driven, the air pump AP supplies air to the first sensor cleaning nozzle 6 via the pipe 8 (continuously during driving). Note that, in the present embodiment, the air pump AP and the pipe 8 constitute an air supply unit.

  The second sensor cleaning nozzle 7 is connected via a pipe 9 to a washer pump P provided in an engine room of the vehicle 1. When the washer pump P is driven, it supplies the cleaning liquid stored in the washer tank T provided in the engine room to the second sensor cleaning nozzle 7 via the pipe 9. In this embodiment, the washer pump P, the washer tank T, and the pipe 9 constitute a cleaning liquid supply unit.

  Further, the vehicle 1 is provided with a control unit 11 capable of controlling the air pump AP and the washer pump P. The control unit 11 is electrically connected to the air pump AP, the washer pump P, the display DSP, the shift lever SL, the on-vehicle camera 5, the cleaning switch SW as a single operation switch, and the like. Note that the cleaning switch SW of the present embodiment is a lever provided near the steering wheel.

  The control unit 11 controls the air mode control for driving the air pump AP to inject only air to the lens 5b based on the operation of the cleaning switch SW, and controls the washer pump P to inject cleaning liquid to the lens 5b. And the washer mode control to be performed.

  Specifically, the control unit 11 of the present embodiment first performs the air mode control based on a single operation of the cleaning switch SW (for example, an operation in which a driver sitting in a driver's seat pulls a lever toward the user), and later performs the air mode control. Performs washer mode control. At this time, the control unit 11 performs the washer mode control when a preset standby time Twait elapses after performing the air mode control. In the washer mode control, the control unit 11 of the present embodiment first performs only washer mode control for injecting only the cleaning liquid, and then performs air washer mode control for injecting the cleaning liquid and air. Further, when performing the washer mode control, the control unit 11 performs final air mode control for driving and controlling the air pump AP so as to inject only air, regardless of the operation of the cleaning switch SW.

Next, specific control (processing) by the control unit 11 of the present embodiment will be described.
As shown in FIG. 2, when the cleaning switch SW is operated (turned on), the control unit 11 performs the processing of step S1 and subsequent steps.

That is, when the cleaning switch SW is operated (turned on), in step S1, the control unit 11 drives the air pump AP (air mode control).
Next, in step S2, the control unit 11 determines whether or not the cleaning switch SW is being operated. If it is determined that the cleaning switch SW is not being operated (off), the process proceeds to step S3, where the air pump is operated. The process is ended with the AP and the washer pump P in a non-driving state (OFF). Further, in step S2, when the control unit 11 determines that the cleaning switch SW is continuously operated, the process proceeds to step S4.

  In step S4, the control unit 11 determines whether or not a preset time Ta has elapsed since the air pump AP was driven (air-on time> Ta?). Move to Further, in step S4, if the control unit 11 determines that the preset time Ta has elapsed after driving the air pump AP, the control unit 11 shifts to step S5 to put the air pump AP in a non-driving state (off), and in step S6 Move to

  In step S6, the control unit 11 determines whether or not the cleaning switch SW is being operated. If it is determined that the cleaning switch SW is not being operated (off), the process proceeds to step S3, where the air pump AP and the air pump AP are operated. The process is terminated with the washer pump P in the non-driving state (off). If the control unit 11 determines in step S6 that the cleaning switch SW has been continuously operated, the process proceeds to step S7.

  In step S7, the control unit 11 determines whether or not a preset standby time Twait has elapsed since the air pump AP was turned off (off) in step S5 (air-off time> Twait?). If it is determined that there is not, the process proceeds to step S6. Further, in step S7, when the control unit 11 determines that the preset standby time Twait has elapsed since the air pump AP was in the non-driving state (off) in step S5, the control unit 11 proceeds to step S8 and drives the washer pump P. (Washer mode control and only washer mode control), and then the process proceeds to step S9.

  In step S9, the control unit 11 determines whether or not the cleaning switch SW is continuously operated. If it is determined that the cleaning switch SW is not operated (OFF), the process proceeds to step S10. In step S10, the control unit 11 drives the air pump AP for a preset time Tf while keeping the washer pump P in a non-driving state (off) (final air mode control), and shifts to step S3, where the air pump AP Then, the process is ended with the washer pump P in the non-driving state (OFF). On the other hand, in step S9, when the control unit 11 determines that the cleaning switch SW is continuously operated, the process proceeds to step S11.

  In step S11, the control unit 11 determines whether or not a preset time Tw has elapsed since the washer pump P was driven in step S8 (washer-on time> Tw?), And determines that it has not elapsed. Then, the process proceeds to step S9. Further, in step S11, when the control unit 11 determines that the preset time Tw has elapsed after driving the washer pump P in step S8, the control unit 11 proceeds to step S12 to drive the air pump AP (washer mode control). And the air washer mode control), and then proceeds to step S13.

  In step S13, the control unit 11 determines whether or not the cleaning switch SW is being operated. If it is determined that the cleaning switch SW is being operated, step S13 is repeated, and the cleaning switch SW is not operated. If (OFF) is determined, the process proceeds to step S10. In step S10, as described above, the control unit 11 drives the air pump AP for a preset time Tf (final air mode control), shifts to step S3, and deactivates the air pump AP and the washer pump P. The process ends as a state (off).

Next, the operation of the thus-configured on-vehicle sensor cleaning device will be described.
For example, as shown in FIG. 3, when the cleaning switch SW is operated (turned on) (timing t1), the air pump AP is driven, and only air is injected from the first sensor cleaning nozzle 6 to the lens 5b.

  Then, when a preset time Ta elapses after driving the air pump AP, the air pump AP is turned off (off). Then, when a preset standby time Twait elapses after the air pump AP is turned off (off), the washer pump P is driven, and only the cleaning liquid is injected from the second sensor cleaning nozzle 7 to the lens 5b.

  Then, when a preset time Tw has elapsed after driving the washer pump P, the air pump AP is driven, and air is injected from the first sensor cleaning nozzle 6 to the lens 5b. At this time, air and the cleaning liquid are simultaneously jetted to the lens 5b.

  When the operation of the cleaning switch SW is stopped (timing t2), the air pump AP is driven for a preset time Tf while the washer pump P is not driven (off), and the lens from the first sensor cleaning nozzle 6 Only air is injected into 5b.

Next, the characteristic effects of the above embodiment will be described below.
(1) A single cleaning switch SW is provided, and based on the operation of the cleaning switch SW, the control unit 11 controls the air mode to drive the air pump AP to inject only air, and to inject the cleaning liquid. The mode is switched between washer mode control in which the washer pump P is drive-controlled. Therefore, the user can easily clean the lens 5b in a desired mode. That is, for example, when the operation switch is provided separately for each mode, the user needs to consider which operation switch corresponds to each mode. By being one, it is possible to suppress such confusion at the time of operation, and it is possible to easily clean the lens 5b in a desired mode.

  (2) Based on a single operation of the cleaning switch SW (for example, an operation in which a driver sitting in a driver's seat pulls a lever toward the user), the control unit 11 first performs air mode control, and then performs washer mode control. Is Therefore, for example, first, when only air is injected by the air mode control and foreign matter such as water droplets on the lens 5b is removed, the operation of the cleaning switch SW is stopped to complete the cleaning without consuming the cleaning liquid. Can be done. Further, for example, when only air is ejected by the air mode control and foreign matter on the lens 5b is not removed, the operation of the washing switch SW is continued, and the washing liquid is ejected by the washer mode control to eject only the air. Foreign matter of the lens 5b such as mud that could not be removed can be removed. By doing so, a single operation of the single cleaning switch SW (for example, an operation in which the driver sitting in the driver's seat pulls the lever forward) can clean the lens 5b satisfactorily without the user getting lost. When the foreign matter can be removed by jetting only air, consumption of the cleaning liquid can be prevented.

  (3) Based on a single operation of the cleaning switch SW, the control unit 11 performs the washer mode control when a preset standby time Twait elapses after the air mode control is performed. By stopping the operation of the cleaning switch SW until Twwait has elapsed, the cleaning can be completed without consuming the cleaning liquid. That is, for example, if the washer mode control is performed immediately after the air mode control is performed, the timing for stopping the operation of the cleaning switch SW is delayed even though the foreign matter can be removed by the injection of only air. There is a possibility that the cleaning liquid is consumed as needed, but this can be prevented.

  (4) In the washer mode control, the control unit 11 first performs only the washer mode control for injecting only the cleaning liquid, and then performs the air washer mode control for injecting the cleaning liquid and air. When it is removed, unnecessary air injection can be prevented.

  (5) When the washer mode control is performed, the final air mode control in which the air pump AP is driven and controlled to inject only air is performed by the control unit 11 regardless of the operation of the cleaning switch SW. However, it is possible to prevent the cleaning liquid from being left attached to the lens 5b without performing another operation.

The above embodiment may be modified as follows.
In the above-described embodiment, in the washer mode control, the control unit 11 first performs only the washer mode control for injecting only the cleaning liquid, and then performs the air washer mode control for injecting the cleaning liquid and the air, but is not limited thereto. Instead, in the washer mode control, the control may be changed to another control as long as the fluid including the cleaning liquid is ejected.

  For example, as shown in FIG. 4, in the washer mode control, only the air washer mode control may be performed. That is, in this example, when the standby time Twait has elapsed, the air pump AP and the washer pump P are simultaneously driven and controlled, and the air and the cleaning liquid are simultaneously jetted to the lens 5b. In this case, for example, the cleaning liquid can be used only when air for improving the cleaning performance is jetted. Therefore, it is possible to preferably remove foreign substances such as mud on the lens 5b while suppressing consumption of the cleaning liquid.

  In the above embodiment, the sensor cleaning nozzle has two nozzles (injection ports) as the first sensor cleaning nozzle 6 for injecting air and the second sensor cleaning nozzle 7 for injecting the cleaning liquid, but is not limited thereto. However, the configuration of the sensor cleaning nozzle may be changed.

  For example, as shown in FIG. 5, a pipe 8 connected to an air pump AP and a pipe 9 connected to a washer pump P are connected together, and only a single injection port is used for air, cleaning liquid only, air and cleaning liquid. Alternatively, the movable nozzle 21 may be capable of ejecting a fluid in which the fluid is mixed and the nozzle 5 can be moved to an optimum position with respect to the lens 5b by the supply pressure of the fluid.

  In the above embodiment, the air pump AP is configured to continuously supply air to the first sensor cleaning nozzle 6 during driving. However, the present invention is not limited to this. For example, the air pump AP compresses air when driven. A configuration in which compressed air is injected by opening the flow path (opening the valve) later to supply air to the first sensor cleaning nozzle 6 may be adopted.

  In this case, for example, as shown in FIG. 6, it is preferable that the control unit 11 synchronize the timing at which the washer pump P is driven with the timing Tx at which the air pump injects air. That is, in this example, when a preset time Tw has elapsed since the washer pump P was driven, the air pump is driven, and the air is intermittently at the timing Tx while the cleaning switch SW is operated (ON). The cleaning liquid is jetted in synchronization with the jetting.

  In this way, the cleaning liquid is not used during the time when the air pump is compressing the air, and the cleaning liquid is used only when the air for improving the cleaning performance is injected (at the timing Tx). it can. Therefore, it is possible to preferably remove foreign substances such as mud on the lens 5b while suppressing consumption of the cleaning liquid.

  In the above embodiment, air mode control is first performed, and then washer mode control is performed based on a single operation using a single cleaning switch SW as a lever (for example, an operation in which a driver sitting in the driver's seat pulls the lever forward). However, the present invention is not limited to this. For example, a single operation switch having another configuration may be used. Further, for example, the air mode control and the washer mode control may be performed by different operations of a single operation switch. In this case, different operations are preferably performed in the same direction.

  For example, as shown in FIGS. 7A to 7C, a single operation switch may be changed to a push button switch SWz provided on an instrument panel, a steering wheel, or the like. As shown in FIG. 7A, the push button switch SWz of this example has a normal position Y1 before being pressed, and an air mode position Y2 of a one-stage pressed position as shown in FIG. 7B. As shown in FIG. 7 (c), it is possible to operate a washer mode position Y3 which is a position further operated (pressed) in the same direction and which is beyond the air mode position. When the push button switch SWz is operated to the air mode position Y2 (see FIG. 7B), the control unit 11 of this example performs the air mode control, and performs the washer mode position Y3 (see FIG. c)), the washer mode control is performed.

  In this way, when the push button switch SWz is operated to the air mode position Y2, the air mode control is performed by the control unit 11, and the push button switch SWz is moved to the washer mode position beyond the air mode position Y2. When the operation is performed at Y3, the control unit 11 performs the washer mode control. Therefore, the user first operates the push button switch SWz to the air mode position Y2 located before the washer mode position Y3, so that only air is ejected by the air mode control and water droplets or the like on the lens 5b are discharged. By stopping the operation of the push button switch SWz when the foreign matter is removed, the cleaning can be completed without consuming the cleaning liquid. Further, for example, when only air is injected by the air mode control and the foreign matter on the lens 5b is not removed, the user pushes the push button switch SWz to the washer mode position Y3 which is beyond the air mode position Y2. By performing the operation (further pressing), the fluid including the cleaning liquid can be ejected by the washer mode control. This makes it possible to remove foreign matter of the lens 5b, such as mud, which could not be removed by jetting only air. In this way, for example, when the user can remove foreign matter by jetting only air without preventing the user from making a mistake in the order (without wondering which direction to operate), consumption of the cleaning liquid can be prevented. Can be.

  In the above-described embodiment, the control unit 11 performs the washer mode control when a preset standby time Twait elapses after performing the air mode control. However, the present invention is not limited to this. For example, the control unit 11 performs the air mode control. Immediately after that, the washer mode control may be performed (without waiting for the waiting time Twwait).

  In the above embodiment, when the control unit 11 performs the washer mode control, the control unit 11 performs the final air mode control for driving and controlling the air pump AP to inject only air regardless of the operation of the cleaning switch SW. The final air mode control may not be performed.

  In the above embodiment, the in-vehicle sensor is the in-vehicle camera 5 provided on the back door 2, but is not limited thereto. For example, the in-vehicle sensor may be embodied as another in-vehicle sensor such as an in-vehicle camera provided in front of the vehicle. Is also good.

  According to the configuration, in the washer mode control, the control unit first performs only the washer mode control for injecting only the cleaning liquid, and then performs the air washer mode control for injecting the cleaning liquid and the air. When the foreign matter can be removed, unnecessary injection of air can be prevented.
