- Each of the predetermined first light amount threshold and the predetermined second light amount threshold is specifically determined, for example, based on a change in the amount of light received with dirt or water droplets attached to the sensor surface of the LiDAR 14.
- step S104 If water droplets are detected on the sensor surface in step S104, the procedure moves to step S106, and if no water droplets are detected on the sensor surface, that is, if it seems that dirt other than water droplets is attached to the sensor surface, the procedure moves to step S106. The procedure moves to step S112.
- step S106 the cleaning control unit 22 controls the cleaning actuator 24 to perform air cleaning for a predetermined period of time by injecting high-pressure air onto the sensor surface of the sensor determined to have water droplets attached.
- dirt on the sensor surface is detected even during air cleaning in step S106.
- the injection pressure, injection amount, and predetermined time of high-pressure air in the air cleaning in step S106 are specifically determined, for example, through an experiment in which water droplets are actually attached to the sensor surface and removed. .
- air cleaning may be continued until it is determined in step S108, which will be described later, whether there is an improvement in sensor performance, and if no improvement in sensor performance is found in step S108, control may be performed to stop air cleaning.
- step S108 it is determined whether the sensor performance has been improved in the object detection unit 16 and the automatic driving control unit 20. Specifically, when the sensor is the camera 12, it is determined that the sensor performance has improved when the brightness difference ⁇ B shown in FIG. 5 is less than a predetermined first brightness difference threshold. Furthermore, in the case where the sensor is LiDAR 14, it is determined that the sensor performance has improved when the amount of laser light reflected from the outside of the vehicle is larger than a predetermined first light amount threshold.
- step S108 if the sensor performance has improved, the procedure moves to step S102, and if the sensor performance has not improved, the procedure moves to step S110.
- step S110 the automatic driving control unit 20 reduces the vehicle speed of the vehicle 300.
- the degree of reduction in vehicle speed is influenced by the speed limit of the driving lane, etc., and is, for example, 10 to 15 km/h.
- step S112 the automatic operation control unit 20 determines whether liquid cleaning control is possible. Specifically, even if the sensor to be cleaned is covered with the cleaning liquid, it will not interfere with object detection for autonomous driving. If there is no predetermined target that should not be affected, it is determined that liquid cleaning control is possible.
- the range is specifically determined according to the injection pressure and injection amount of the cleaning liquid of the cleaning actuator 24.
- the sensor to be cleaned does not interfere with object detection for automatic operation even if it is covered with the cleaning liquid, for example, the dirt detected by the dirt detection unit 18 is slight and can be easily removed by spraying the cleaning liquid. If possible, or if only some of the cameras 12A to 12D and LiDARs 14A to 14D, which are multiple sensors, are to be cleaned and the sensors other than those to be cleaned are functioning normally. It is.
- the dirt detected by the dirt detection unit 18 is slight and can be easily removed by spraying cleaning liquid, for example, if the dirt detection unit 18 and the sensor are the camera 12, the brightness difference ⁇ B shown in FIG. This is a case where the brightness difference is approximately equal to the first brightness difference threshold, and if the sensor is LiDAR 14, the amount of laser light reflected from the outside of the vehicle 300 is approximately equal to the predetermined first light amount threshold.
- step S112 if liquid cleaning control is possible, a command to clean the sensor with cleaning liquid is output to the cleaning control unit 22, and the procedure moves to step S114; if liquid cleaning control is not possible, the procedure goes to step S102. Transition.
- step S114 the cleaning control unit 22 determines whether liquid cleaning is possible. Specifically, if liquid cleaning cannot be performed due to constraints on the cleaning actuator 24 side, the determination is "No", and if it is possible, the determination is "Yes".
- the restriction on the cleaning actuator 24 side in step S114 is, for example, when multiple sensors are to be cleaned, it is not possible to clean multiple sensors at the same time due to the limitations of the pump that pumps the cleaning liquid, so some sensors are forced to wait for cleaning. This is the case when the product is stored away, or when the cleaning itself cannot be done due to insufficient cleaning solution.
- step S114 if liquid cleaning is possible, the procedure moves to step S116, and if liquid cleaning is not possible, the procedure moves to step S122.
- step S116 the cleaning control unit 22 controls the cleaning actuator 24 to perform liquid cleaning for a predetermined period of time in which cleaning liquid is sprayed onto the sensor surface of the sensor to be cleaned.
- dirt on the sensor surface is detected even during liquid cleaning in step S116.
- the injection pressure, injection amount, and predetermined time of the cleaning liquid in the liquid cleaning in step S116 are specifically determined, for example, through an experiment in which dirt is actually removed from the sensor surface.
- step S118 the cleaning control unit 22 notifies that the sensor to be cleaned is being cleaned with liquid. This notification is performed because the cleaning liquid covers the sensor surface due to liquid cleaning, which may affect sensor detection, and also because the cleaning liquid is scattered around the vehicle 300. On the other hand, since air cleaning does not directly affect sensor detection or objects existing around the vehicle 300 due to cleaning, the cleaning control unit 22 informs the automatic operation control unit 20 that cleaning is in progress during air cleaning. Notification is not required.
- step S120 it is determined whether the sensor performance has been improved in the object detection unit 16 and the automatic driving control unit 20. Specifically, when the sensor is the camera 12, it is determined that the sensor performance has improved when the brightness difference ⁇ B shown in FIG. 5 is less than a predetermined first brightness difference threshold. Furthermore, in the case where the sensor is LiDAR 14, it is determined that the sensor performance has improved when the amount of laser light reflected from the outside of the vehicle is larger than a predetermined first light amount threshold.
- step S120 If the sensor performance has improved in step S120, the procedure moves to step S102 to restart detection of dirt on the sensor surface, and if the sensor performance has not improved, the procedure moves to step S122.
- the automatic driving control unit 20 switches from automatic driving to driving support. Specifically, it is a warning display of an obstacle detected by the object detection unit 16, a lane departure warning, etc.
- measures such as further reducing the vehicle speed, reducing the level of automatic driving such as prohibiting automatic lane changes, or discontinuing automatic driving may be taken.
- the execution of measures such as reducing the vehicle speed, prohibiting lane changes, etc. to reduce the level of automatic driving, or canceling automatic driving differs depending on the location of the sensor whose dirt could not be removed. For example, if dirt cannot be removed from the sensor surface of the camera 12A or LiDAR 14A that acquires information in front of the vehicle 300, this will have a large impact on automatic driving, so measures are taken to stop automatic driving.
- step S124 the automatic driving control unit 20 determines whether automatic driving has been stopped by the driver. If the automatic operation is stopped in step S124, the automatic operation control unit 20 outputs a command to the cleaning control unit 22 to stop cleaning with the cleaning liquid, and ends the series of processes including liquid cleaning shown in FIG. do. Even when liquid cleaning is terminated, air cleaning may be continued. If the automatic operation is not stopped in step S124, the procedure moves to step S102, and detection of dirt on the sensor surface is restarted.
- the cleaning control unit 22 performs automatic operation to indicate that the sensors are being cleaned. By notifying the control unit 20, even if the sensor to be cleaned is covered with cleaning liquid, the influence on object detection for automatic driving can be suppressed.
- FIG. 6 is a block diagram showing an example of the configuration of the sensor cleaning device 200 according to this embodiment.
- the cleaning ECU 60 including the cleaning control unit 62 is a circuit independent of the automatic operation ECU 50, and the dirt detection unit 18 transmits information on detected dirt on the sensor surface only to the cleaning control unit 62.
- the output is also output to the automatic driving control unit 20, but the other configurations are the same as the first embodiment.
- the same reference numerals are used to omit the detailed explanation.
- the automatic operation control unit 20 receives information about dirt on the sensor surface from the dirt detection unit 18, and determines which sensor is to be cleaned. It is possible to quickly determine the extent to which object detection is affected when the sensor is cleaned with liquid.
- FIG. 7 is a block diagram showing an example of the configuration of the sensor cleaning device 210 according to this embodiment.
- the dirt detection section 18 does not output information on detected dirt on the sensor surface to the cleaning control section 82 of the cleaning ECU 80, but outputs it to the automatic operation control section 20.
- the second embodiment is different from the second embodiment, other configurations are the same as the second embodiment, so the same configurations as the second embodiment are given the same reference numerals and detailed explanations are omitted.
- the automatic operation control section 20 can: Controlling the automatic operation of the vehicle 300 and cleaning the sensor surface are performed comprehensively, thereby contributing to suppressing the influence of liquid cleaning on the automatic operation.
