Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening/closing body control device that controls operating noise of an opening/closing body of a vehicle.

BACKGROUND ART Conventionally, there is known an opening/closing body control device that emits a notification sound such as a buzzer to alert people around the vehicle when an opening/closing body (rear slide door or the like) of the vehicle is activated (for example, Patent Documents 1 to 1). 2).

The opening/closing body control device described in Patent Document 1 is a technique in which noise around the vehicle is collected by a plurality of microphones, and the volume of the notification sound is changed based on the volume of the collected noise. For example, the volume of the notification sound is increased when the surroundings of the vehicle are noisy, and the volume of the notification sound is reduced when the surroundings of the vehicle are quiet.

The opening/closing body control device described in Patent Document 2 is a technique of changing the volume of the notification sound based on the user's swipe operation detected by a plurality of distance sensors provided on the opening/closing body. For example, when the swipe operation is performed at a position far from the distance sensor, the notification sound is set to the standard volume, and when the swipe operation is performed at a position close to the distance sensor, the notification sound is set to a low volume. There is.

JP, 2006-144432, A JP, 2014-177819, A

In the technique described in Patent Document 1, since the notification sound is uniformly set due to the noise around the vehicle, the notification sound does not always match the notification volume expected by the user. For example, when an infant is sleeping with the backrest of the seat tilted in the car, the infant may be awakened by a loud sound.

In the technique described in Patent Document 2, since the notification sound can be changed by the user operation, it is possible to bring the notification sound closer to the notification volume expected by the user compared to the technique described in Patent Document 1. However, the user is required to perform a complicated work of changing the notification volume, which reduces the convenience.

Therefore, there is a demand for an opening/closing body control device that provides the operation sound of the opening/closing body expected by the user without impairing the convenience of the user.

A characteristic configuration of an opening/closing body control device according to the present invention includes a determination unit that determines a sleep state of an occupant who is in a vehicle, and a control unit that controls an operating sound of an opening/closing body opened and closed by a drive device. As a result of the determination by the determination unit, the control unit controls the operation sound of the opening/closing body to be smaller when the occupant is sleeping than when the occupant is not sleeping.

In this configuration, the operating sound of the opening/closing body is changed in association with the sleep state of the occupant. That is, when the occupant is sleeping, the operating sound of the opening/closing body opened and closed by the drive device is controlled to be lower than the normal operating sound when the occupant is not sleeping. Thereby, for example, when there is an occupant such as an infant sleeping in the vehicle, it is possible to prevent the inconvenience that the infant gets up due to a large operating noise. Moreover, since the control unit controls the operating sound of the opening/closing body, the user does not need to set the operating sound, which is highly convenient. Therefore, the opening/closing body control device of this configuration can provide the opening/closing body operating sound expected by the user without impairing the convenience of the user.

Another characteristic configuration is that the operation sound is a notification sound for notifying the outside when the opening/closing body is opened/closed.

If the operation sound of the opening/closing body is used as a notification sound to the outside as in this configuration, for example, when the occupant is sleeping, it is difficult to hear the notification sound and it is difficult to wake up, and people around the vehicle The opening/closing of the opening/closing body can be recognized.

Another characteristic configuration is that the operation sound is a mechanical sound generated when the opening/closing body opens and closes.

If the operation sound is the mechanical sound of the opening/closing body as in this configuration, the operation sound can be reduced by, for example, decreasing the opening/closing speed of the opening/closing body, and the mechanical sound awakens the occupant during sleep. Inconvenience can be prevented.

Another characteristic configuration is that the determination of the sleep state by the determination unit includes a determination of the sleep depth of the occupant, and the control unit determines the sleep depth of the occupant by the determination unit. The point is that the magnitude of the operating noise is changed according to the determination result.

By changing the loudness of the operation sound of the opening and closing body according to the depth of sleep of the occupant as in this configuration, for example, the operation sound is relatively increased for an occupant having a deep sleep and the occupant having a light sleep. It is possible to make the operating noise relatively low. As a result, it is possible to make people around the vehicle recognize that the opening/closing body is opening and closing, without waking up the sleeping occupant. Therefore, the safety around the vehicle and the comfort of the occupant can both be achieved.

In another characteristic configuration, the control unit includes a seat control unit that controls the tilt angle and the operation speed of the backrest by a seat device that changes a tilt angle of the backrest of a seat on which the occupant is seated. The seat control unit, when the determination unit determines that the occupant is sleeping, when the opening and closing body is opened, the tilt angle of the backrest from the tilted posture to the upright posture. The point is that the operating speed to be changed is made smaller than the normal speed.

By having a seat control unit like this configuration, for example, when an infant is sleeping by tilting the backrest of the seat, the user can easily hold the infant by raising the backrest together with the opening operation of the opening and closing body. Become. Moreover, when the occupant is sleeping, the operation speed for changing the backrest from the tilted posture to the upright posture is reduced, so that the sleeping occupant is not forced to awaken. Therefore, the convenience of the user and the comfort of the occupant can both be achieved.

[Opening/closing body control device]
The opening/closing body control device X according to the present embodiment includes the above-described determination unit 61 and control unit 6. Hereinafter, the control mode in the opening/closing body control device X will be described in detail.

The sleep state determination unit 61b determines the sleep state of the occupant in the automobile C based on the in-vehicle camera 51 and the like. Then, as a result of the determination by the sleep state determination unit 61b, the opening/closing body control unit 62 of the control unit 6 controls so that the operating sound of the door D becomes smaller when the occupant is sleeping than when the occupant is not sleeping. To do. Here, the operation sound is a notification sound notified to the outside from the notification device 72 when the door D is opened or closed, or a mechanical sound generated when the door D is opened or closed by the door drive unit 73. The volume of the mechanical sound is adjusted by controlling the opening/closing speed of the door driving unit 73 by the opening/closing body control unit 62. Specifically, when the door opening/closing speed is made lower than the standard speed, the mechanical noise becomes small, and when the door opening/closing speed is made higher than the standard speed, the mechanical sound becomes louder.

The opening/closing body control unit 62 changes the loudness of the operation sound of the door D according to the sleep depth (sleep depth) of the occupant determined by the sleep state determination unit 61b. Specifically, when the occupant has a deep sleep depth, the operating sound of the door D is unlikely to wake up, so the opening/closing body control unit 62 prioritizes the attention to the surroundings and operates the door D. Control so that the sound becomes relatively loud. On the other hand, when the sleep depth of the occupant is shallow, there is a high possibility of awakening due to the operation sound of the door D, and thus the necessity of alerting the surroundings by the hazard determining unit 61c and the external environment determining unit 61d is low. After determining, the opening/closing body control unit 62 controls so that the operating noise of the door D becomes relatively small. As a result, it is possible to make people around the vehicle recognize that the door D is opening and closing without waking up the sleeping passenger.

When the sleep state determining unit 61b determines that the occupant is sleeping, the seat control unit 64, when the door D is opened by the door driving unit 73, opens the seat back on which the occupant is seated. The seat device 74 is controlled so that the operating speed for changing from the tilted posture to the upright posture is smaller than the standard speed (normal speed). Thus, for example, when the infant is sleeping with the backrest tilted, the user can easily hold the infant by raising the backrest together with the opening operation of the seat device 74. Moreover, when the occupant is sleeping, the operating speed of the backrest is reduced, so that the sleeping occupant is not forced to awaken.

The hazard determination unit 61c determines whether or not the occupant, luggage, etc. near the door D of the vehicle C detected by the vehicle camera 51 or the like will be harmed by the opening/closing operation of the door D. Then, as a result of the determination by the hazard determination unit 61c, if the hazard is likely to occur and caution is required, further, the external environment determination unit 61d may sound a notification sound based on the surrounding situation. Determine whether or not. Then, as a result of the determination by the external environment determination unit 61d, when the notification sound may be emitted, the notification sound control unit 63 changes the tone color of the notification sound of the notification device 72 or is higher than the standard volume (normal volume). The control such as increasing the notification volume is executed. On the other hand, as a result of the determination by the external environment determination unit 61d, when it is not possible to emit the notification sound, the illumination control unit 65 executes control such as blinking the illumination of the illumination device 75.

The external environment determination unit 61d determines whether or not attention is required by opening/closing the door D based on the external environment of the vehicle C detected by the vehicle exterior camera 52, the distance sensor 53, the raindrop sensor 55, and the like. .. For example, when it is recognized that there is an obstacle near the door D based on the vehicle exterior camera 52 and the distance sensor 53, the external environment determination unit 61d determines that the door D may hit the obstacle by opening the door D. It is determined that attention is required. Then, as a result of the determination made by the external environment determination unit 61d, when attention is required, if the raindrop sensor 55 detects rain, the notification sound control unit 63 controls to increase the notification volume of the notification device 72. Run. As a result of the determination by the external environment determination unit 61d, when the attention is not required, the opening degree of the door D is determined according to the size of the load detected by the vehicle exterior camera 52, and the opening/closing body control unit 62 causes the door drive unit to operate. The opening degree of the door D by 73 is controlled, and the notification sound control unit 63 executes control such that the notification sound volume of the notification device 72 is set to the standard sound volume.

Subsequently, an example of a control flow of the opening/closing body control device X will be described with reference to FIGS. FIG. 2 shows an example in which the operation sound of the rear slide door D is changed according to the sleep state of the occupant.

First, the sleep state determination unit 61b determines whether or not there is an instruction to open the rear slide door D by pressing the slide door opening/closing button of the operation unit 71 or grasping the rear door handle (#21). .. Then, when there is an instruction to open the rear slide door D (Yes in #21), the sleep state determination unit 61b determines the sleep state of the occupant (#22). At this time, the priority determination unit 61a determines that the determination by the hazard determination unit 61c and the external environment determination unit 61d has a higher priority than the determination by the sleep state determination unit 61b, and the hazard determination unit 61c and the external environment determination are performed. The unit 61d determines whether or not attention is required (#23). If there is an occupant, luggage, or the like near the rear slide door D, which causes harm due to the opening/closing operation of the rear slide door D (#23 Yes), the notification sound control unit 63 causes the notification device 72 to notify the alarm device 72. The control for making the notification volume be louder than the standard volume is executed (#24). In addition, when it is recognized that there is an obstacle near the rear slide door D outside the vehicle according to the determination result of the external environment determination unit 61d (#23 Yes), the notification sound control unit 63 sets the notification volume of the notification device 72 to the standard. A control for making a sound louder than the volume is executed (#24).

On the other hand, when the hazard determination unit 61c and the external environment determination unit 61d determine that the alert is not necessary (No in #23), the sleep state determination unit 61b determines whether the sleep depth is shallower than a predetermined depth. Yes (#25). When the sleep depth is shallower than the predetermined depth (#25 Yes), the alarm sound control unit 63 and the opening/closing body control unit 62 indicate that the operation sound of the rear slide door D is a standard set value (normal operation when the occupant is not sleeping). Sound) and is further smaller than the sleep set value (<standard set value) when the occupant is sleeping. Specifically, the notification sound control unit 63 controls the notification sound to be notified to the outside to be extremely small or silent, and the opening/closing body control unit 62 causes the opening speed of the rear slide door D to be higher than the standard speed. It is controlled to be small (#26). On the other hand, when the sleep depth is deeper than the predetermined depth (#25 No), the notification sound control unit 63 and the opening/closing body control unit 62 determine that the operation sound of the rear slide door D is higher than the standard setting value when the occupant is not sleeping. It is controlled to be smaller and larger than the sleep set value (<standard set value) when the occupant is sleeping. Specifically, the notification sound control unit 63 controls the notification sound to be notified to the outside to be slightly smaller than the standard set value, and the opening/closing body control unit 62 sets the opening speed of the rear slide door D to the standard speed. Is controlled in the same manner as (#27). In this way, when the occupant is sleeping, the alarm sound is reduced, so that the sleeping occupant is not forced to wake up. Moreover, since the operation sound of the rear slide door D is changed according to the sleep depth of the occupant, the comfort of the occupant is further improved. The control flow from #21 to #27 in FIG. 2 can be applied not only to the opening operation of the rear slide door D but also to the opening operation of the back door D.

Next, the sleep state determining unit 61b determines whether or not the backrest of the seat of the seat device 74 is tilted (#28). When the backrest of the seat is tilted (Yes in #28), it is determined whether or not the sleep depth is shallower than a predetermined depth, as in #25 (#29). When the sleep depth is shallower than the predetermined depth (Yes in #29), the seat control unit 64 reduces the operation speed for returning the seat backrest from the tilted posture to the upright posture as compared with the standard speed (#30). On the other hand, when the sleep depth is deeper than the predetermined depth (No in #29), the seat control unit 64 sets the operation speed for returning the seat backrest from the tilted posture to the upright posture to the standard speed (#31). In this way, when the occupant is sleeping, the operating speed of the backrest is reduced, so that the occupant during sleep is not awakened by force, and the backrest is caused together with the opening operation of the rear slide door D, The user can easily hold the infant.

FIG. 3 shows an example of changing the notification form at the time of opening/closing the door when there is a risk of opening/closing the door D.

First, the hazard determination unit 61c recognizes the remote key 1 as a result of the collation performed by the collation unit 3 and issues an instruction to open/close the rear slide door D by gripping the rear door handle or a back door open operation button of the remote key 1. It is determined whether or not there is a back door opening operation instruction by pressing (#32). Then, when there is a door opening/closing instruction (a generic name of opening/closing operation instruction of the rear slide door D and a back door opening operation instruction, hereinafter referred to as “door opening/closing instruction”) (#32 Yes), the hazard determination unit 61c determines that It is determined whether the opening/closing operation causes harm (#33). Specifically, when the occupant leans on the rear slide door D and is sleeping, the hazard determination unit 61c calls attention to the fact that the occupant may be involved in the opening operation of the door D by opening the door D. Is determined to be necessary (Yes in #34). In addition, when the luggage is leaning on the back door D, the hazard determination unit 61c determines that caution is necessary because the luggage may fall outside by opening the back door D (#34 Yes). ). Furthermore, when the occupant or a person outside the vehicle is in the movable range of the door D or the window, the hazard determination unit 61c needs to be alerted that the occupant may be caught during the closing operation of the door D or the window. (#34 Yes).

Next, the external environment determination unit 61d determines whether or not notification is possible depending on the situation of the surrounding environment (#35). As an example, when the external environment determination unit 61d determines that the automobile C is stopped in a residential area at night (No in #35), it is not appropriate to emit the notification sound, so the illumination control unit 65 causes the illumination device 75 to emit light. Flashes to call attention (#37). On the other hand, when the external environment determination unit 61d determines that the car C is stopped in the daytime commercial area (#35 Yes), the notification sound control unit 63 causes the notification device to have a small effect even if the notification sound is emitted. The notification sound (tone) of 72 is changed to a warning sound or the notification sound volume is increased (#36). As a result, it is possible to call attention to the person and eliminate the hazard.

FIG. 4 shows an example of changing the notification form and the opening degree of the door D when the door D is opened and closed according to the surrounding environment.

As a result of the verification by the verification unit 3, the remote key 1 is authenticated, and an instruction to open/close the rear slide door D by holding the rear door handle or an instruction to open the back door by pressing the back door open operation button of the remote key 1 is issued. It is determined whether there is any (#41). Then, when the door opening/closing instruction is given (#41 Yes), the external environment determination unit 61d determines whether the opening/closing operation of the door D affects the surrounding environment (#42). If there is an obstacle in the vicinity of the door D, the external environment determination unit 61d determines that it is necessary to call attention because the door D may hit the obstacle by opening the door D (#43 Yes). Next, the external environment determination unit 61d determines whether or not rain has been detected by the raindrop sensor 55 (#44). When rain is detected (#44 Yes), the notification sound control unit 63 executes control such that the notification volume of the notification device 72 is increased (#45). As a result, there is no inconvenience that the alarm sound cannot be heard due to the rain sound, and the attention can be surely given to the surrounding people. On the other hand, when rain is not detected (No in #44), the notification sound control unit 63 executes control to set the notification sound volume of the notification device 72 to the standard sound volume (#46).

As a result of the determination in #43, if attention is not required (No in #43), the external environment determination unit 61d determines whether or not rain has been detected by the raindrop sensor 55 (#47). When rain is detected (Yes in #47), the external environment determination unit 61d determines the opening degree of the door D according to the size of the load detected by the vehicle exterior camera 52 (#48). When the load is small as a result of the determination by the external environment determination unit 61d, the opening/closing body control unit 62 performs control to reduce the opening degree of the door D to be smaller than the normal opening degree in a range in which the load can be loaded (# 49). As a result, when the cargo is stored in the vehicle, it is possible to prevent rain from entering the vehicle and flooding the vehicle. On the other hand, as a result of the determination of #47, if rain is not detected (#47 No) or as a result of the determination of #48, if the load is large (#48 No), the opening/closing body control unit 62 controls the opening degree of the door D. The control for making the normal opening (maximum) is executed (#50).

As explained above, the opening/closing control of the door D suitable for various scenes is executed by the opening/closing body control device X in the present embodiment. The control flow of the opening/closing body control device X described above can be appropriately combined as necessary.
