Hereinafter, an embodiment in which the present invention is applied to a power slide door system of a vehicle such as an automobile will be described with reference to the drawings.
FIG. 1 is a block diagram showing an electrical configuration of the present embodiment. As shown in the figure, a door ECU (Electronic Control Unit) 10 installed in the vehicle body is mainly composed of, for example, a micro controller (MCU), and a power sliding door device 20 also installed in the vehicle body. And are electrically connected. The power slide door device 20 is linked to a slide door 1 as a door through an appropriate transmission mechanism (not shown). The sliding door 1 is supported on a side portion of the vehicle body through an appropriate support member (not shown) so as to be movable in the front-rear direction, and opens and closes the opening for getting on and off in accordance with the movement in the front-rear direction. . The door ECU 10 electrically opens and closes the sliding door 1 by driving control of the power sliding door device 20.

  That is, the power slide door device 20 includes a door motor 21, an electromagnetic clutch 22, and a pair of pulse sensors 23. The door ECU 10 controls the opening / closing operation of the sliding door 1 by drivingly controlling the door motor 21. Further, the door ECU 10 controls the driving of the electromagnetic clutch 22 to switch the power transmission between the door motor 21 and the slide door 1 between connection and disconnection. This is because the power transmission is set to a connected state only when the slide door 1 is electrically opened / closed and the slide door 1 is opened / closed manually to realize a smooth opening / closing operation. . Further, the door ECU 10 determines the rotation direction (forward rotation or reverse rotation), rotation amount and rotation speed of the door motor 21, that is, the opening / closing position of the slide door 1, based on a pair of pulse signals with different phases output from both pulse sensors 23. And the opening and closing speed is detected. The door ECU 10 controls the opening / closing operation of the slide door 1 by the power slide door device 20 based on the pulse signals from the pulse sensors 23.

  The door ECU 10 is electrically connected to a latch mechanism (not shown) that holds the slide door 1 in a fully closed state or a fully open state, and a release motor 11 and a closer motor 12 that are linked via an appropriate transmission mechanism. ing. The release motor 11 transmits the power to the latch mechanism, thereby releasing the holding of the slide door 1 in the fully closed state or the fully open state by the latch mechanism. Thereby, the slide door 1 will be in an openable state or a closeable state. On the other hand, the closer motor 12 transmits the power to the latch mechanism, thereby holding the slide door 1 in the half door state in the fully closed state by the latch mechanism.

  In addition, the door ECU 10 is electrically connected to a control switch 15 installed on the dashboard, for example, facing the driver's seat side. When the control switch 15 is pushed by the driver (user), the door ECU 10 controls the opening / closing operation of the slide door 1 by the power slide door device 20 based on the operation signal. Further, the door ECU 10 is electrically connected to an inside handle switch 16 and an outside handle switch 17 respectively installed on the inside door handle and the outside door handle. The door ECU 10 performs an opening / closing operation of the slide door 1 by the power slide door device 20 based on an operation signal from the inside handle switch 16 or the outside handle switch 17 accompanying the operation of either the inside door handle or the outside door handle. Control. Further, the door ECU 10 is electrically connected to a latch switch 18 installed in the latch mechanism. The door ECU 10 operates from a latch switch 18 according to the operating position of the latch mechanism (the position where the slide door 1 is held in the fully closed state or the fully opened state, the position where the slide door 1 is held in the half door state, or the position where the slide door 1 is released). Based on this detection signal, the opening / closing operation of the sliding door 1 by the power sliding door device 20 is controlled.

  Furthermore, the door ECU 10 is electrically connected to a pressure detection type touch sensor 19 fixed along the edge of the slide door 1, and foreign matter generated by the slide door 1 based on a detection signal of the touch sensor 19. Etc. are detected. The door ECU 10 detects the pinching by the slide door 1 in a well-known manner based on the opening / closing speed of the slide door 1 detected by the pulse sensor 23.

  On the other hand, the door ECU 10 is electrically connected to the in-vehicle device 31 mounted on the vehicle body. The in-vehicle device 31 constitutes a wireless communication system with the portable device 36 carried by the user, receives a transmission signal accompanying the pressing operation of the wireless switch 36 a of the portable device 36, and sends this to the door ECU 10. Send. The door ECU 10 controls the opening / closing operation of the slide door 1 by the power slide door device 20 based on a signal from the in-vehicle device 31.

  The door ECU 10 is electrically connected to an LED (Light Emitting Diode) 41 that constitutes a light notification means, and a notification pattern (flashing pattern) of the LED 41 according to the state (door state) of the slide door 1. ) (Light notification control means). For example, the door ECU 10 controls the lighting time of the LED 41, the blinking cycle, the number of repetitions of blinking, and the like. In addition, LED41 is arrange | positioned in the appropriate position which can be recognized from the vehicle periphery (external).

  Further, the door ECU 10 is electrically connected to a buzzer 42 that constitutes a sound notification unit, and controls a notification sound of the buzzer 42. That is, the door ECU 10 is electrically connected to the microphone 43 constituting the sound environment detection means. The microphone 43 inputs sound around the vehicle, and the door ECU 10 detects the environment (for example, noise level and frequency component) based on the sound input from the microphone 43, and based on the sound environment. The volume and frequency of notification (sounding) by the buzzer 42 are controlled (sound notification control means).

  The door ECU 10 is electrically connected to a timepiece 44 that constitutes an ambient environment detection unit and a sound environment detection unit. The door ECU 10 detects the surrounding environment (for example, a time zone such as daytime or nighttime) based on the time input from the clock 44, and selects the notification by the LED 41 and the notification (sounding) by the buzzer 42 based on the surrounding environment. (Selection means). Alternatively, the door ECU 10 detects a sound environment (for example, a time zone) based on the time input from the clock 44 and controls the volume and frequency of notification (sounding) by the buzzer 42 based on the sound environment (sound notification). Control means). Specifically, when the time inputted from the clock 44 is in the time zone from 0:00 am to 6:00 am, the door ECU 10 prohibits notification (sounding) by the buzzer 42. On the other hand, when the time input from the clock 44 is in a time zone other than the above (from 6:00 am to 0:00 am), the buzzer 42 notifies (sounds) according to the sound environment (time, noise level, frequency component, etc.). ) To control the volume and frequency.

  Next, a basic drive control mode of the power slide door device 20 by the door ECU 10 will be described with reference to the flowchart of FIG. That is, for the sake of convenience, description of drive control modes of the release motor 11 and the closer motor 12 by the door ECU 10 is omitted. This process is started when a predetermined operating condition is satisfied when the slide door 1 is fully closed or fully opened. Specifically, when an ignition switch (not shown) is turned on, (a) a main switch (not shown) for setting the power sliding door system to an activated state is turned on, and (b) the battery voltage is set to a predetermined voltage ( For example, 11V) or higher, (c) the condition of either stepping on the shift lever P range or the foot brake, or stepping on the parking brake is satisfied, and (d) the vehicle speed is lower than a predetermined speed (for example, 3 km / h) , (E) The touch sensor 19 is not in a disconnection detection state, and is activated when all of them are established. Alternatively, when the ignition switch is turned off, it is activated when all of (a) the main switch is on, (b) the battery voltage is equal to or higher than the predetermined voltage, and (c) the touch sensor 19 is not in the disconnection detection state. Is done.

  When the processing shifts to this routine, the door ECU 10 determines in S (step) 1 whether or not there is an operation signal indicating an opening / closing operation from the control switch 15, the inside handle switch 16, the outside handle switch 17 or the wireless switch 36a. to decide. When it is determined that there is no operation signal, the door ECU 10 ends the subsequent processing as it is. When it is determined that there is the operation signal, the door ECU 10 starts the opening / closing operation of the slide door 1 in S2. That is, the door ECU 10 drives the electromagnetic clutch 22 to switch the power transmission between the slide door 1 and the door motor 21 to the connected state, and drives the door motor 21 to open and close the slide door 1. At this time, the door ECU 10 drives and controls the door motor 21 based on the pulse signal from the pulse sensor 23.

  Subsequently, in S <b> 3, the door ECU 10 determines whether or not the slide door 1 is caught. If it is determined that there is a pinch, the door ECU 10 performs a well-known pinch handling process (for example, reverse driving of the door motor 21) in S4 and ends the subsequent process. On the other hand, if it is determined in S3 that there is no pinching, in S5, the door ECU 10 determines whether or not the slide door 1 is in the fully open position or the fully closed position.

  Here, if it is determined that the slide door 1 is not in the fully open position or the fully closed position, the door ECU 10 returns to S3 and repeats the same processing. If it is determined in S5 that the slide door 1 is in the fully open position or the fully closed position, the door ECU 10 stops the opening / closing operation of the slide door 1 in S6 and ends the subsequent processing.

  That is, when the opening / closing operation of the sliding door 1 is started in S2, the door ECU 10 continues the opening / closing operation of the sliding door 1 until the sliding door 1 reaches the fully open position or the fully closed position unless it is determined that there is pinching. To do.

In the present embodiment, the door ECU 10 drives the buzzer 42 and the like in accordance with the opening / closing operation (door state) of the slide door 1. This is to allow users around the vehicle to recognize the door state.
Specifically, when the control switch 15 or the wireless switch 36a is pushed while the slide door 1 is fully closed or fully opened, or the inside door handle or the outside door handle is operated, the door ECU 10 Prior to the start of the opening / closing operation, the buzzer 42 is blown for a predetermined time. Further, in the closing operation of the slide door 1, the door ECU 10 sounds the buzzer 42 intermittently during the operation.

  Further, when the sliding door 1 is opened when the sliding door glass (not shown) is open, the sliding door 1 is held at an intermediate stopper position for mechanically stopping the sliding door 1 at an intermediate position. When the state continues for a predetermined time, the door ECU 10 ends the holding and blows the buzzer 42 for a predetermined time to switch to the manual state. Note that the door ECU 10 performs brake control for a predetermined time after switching to the manual state. This brake control is intended to make it difficult to open the sliding door 1 in the opening direction, and repeatedly opens and closes the electromagnetic clutch 22 repeatedly. Thereby, for example, when the vehicle suddenly starts, the sliding door 1 can be prevented from being opened due to inertia, and the user can be made aware.

  Further, when any of the sliding doors 1 is opened or closed based on the pressing operation of the control switch 15 or the wireless switch 36a or the opening / closing operation of the inside door handle or the outside door handle, the door ECU 10 Prior to the reversing operation, the buzzer 42 is blown for a predetermined time.

  Further, the buzzer 42 is operated after the control switch 15 or the wireless switch 36a is pushed with the slide door fully closed or fully opened, or after the inside door handle or the outside door handle is operated with the slide door fully opened. During the sounding, the door ECU 10 sounds the buzzer 42 for a certain time without starting the operation of the slide door 1 when any of the above-described operating conditions is removed.

  Furthermore, when any of the above operating conditions is removed during the opening / closing operation of the slide door 1 based on the pressing operation of the control switch 15 or the wireless switch 36a or the operation of the inside door handle or the outside door handle, the door ECU 10 The opening / closing operation of the sliding door 1 is stopped, and the buzzer 42 is blown for a predetermined time. And door ECU10 performs brake control only for the definite period of time.

  In this embodiment, in addition to the basic opening / closing operation (door state) of the slide door 1, the door ECU 10 detects the start of the operation of the slide door 1 regardless of the operation of the control switch 15 or the like. The open / close operation (so-called assist operation) of the sliding door 1 also drives the buzzer 42 and the like in accordance with the above.

  When the door ECU 10 determines that the above-described pinching is present, the door ECU 10 stops the opening / closing operation of the slide door 1 and blows the buzzer 42 for a predetermined time prior to the reversing operation. In particular, when the door ECU 10 determines that there is pinching in the same direction twice, the door ECU 10 stops the opening / closing operation of the slide door 1 and blows the buzzer 42 for a predetermined time to switch to the manual state. Note that the door ECU 10 performs brake control for a predetermined time after switching to the manual state.

Next, the notification mode by the door ECU 10 will be described with reference to the flowchart of FIG.
As shown in FIG. 3, when the process proceeds to this routine, in S11, the door ECU 10 obtains information on the surrounding environment (time zone) based on the time inputted from the clock 44, and the sound based on the surrounding environment. It is determined whether or not the notification by the buzzer 42 is performed. Then, when it is determined that notification by sound is performed, the door ECU 10 determines the sound environment (time zone, noise level, frequency component) based on the sound input from the microphone 43 and the time input from the clock 44 in S12. In S13, a sound notification method is set based on the acquired sound environment information. That is, the door ECU 10 sets the volume and frequency of notification (sounding) by the buzzer 42.

  On the other hand, when it is determined in S11 that notification by sound is not performed, the door ECU 10 sets a notification method using light (LED 41) in S14. That is, door ECU10 sets the alerting | reporting pattern (flashing pattern) by LED41 according to a door state.

  In S15, the door ECU 10 drives and controls the buzzer 42 or the LED 41 in accordance with the sound or light notification method set in S13 or S14. As a result, the buzzer 42 sounds at the notification volume and frequency set, or the LED 41 is turned on (flashes) with the notification pattern set.

As described above in detail, according to the present embodiment, the following effects can be obtained.
(1) In the present embodiment, for example, when notification by sound is preferable due to surrounding conditions, the door ECU 10 deselects the drive of the buzzer 42, that is, does not perform notification by sound, and gives it to the user. Discomfort can be eliminated.

  (2) In the present embodiment, for example, when there is an unfavorable surrounding environment (time zone) in which sound notification is not preferable, the door ECU 10 automatically deselects the drive of the buzzer 42, that is, from sound notification to light notification. By switching to, operability can be improved. For example, in a situation where the slide door 1 is operated in a time zone such as midnight, when the vehicle position and the house are adjacent to each other, concern for the neighborhood can be eliminated by eliminating the notification sound.

  (3) In this embodiment, the door ECU 10 can make the user easily recognize the corresponding door state by controlling the notification pattern (lighting pattern) by the LED 41 according to the door state.

  (4) In the present embodiment, the door ECU 10 controls the sound volume and frequency of the notification by the buzzer 42 based on the detected sound environment, thereby notifying the user with the optimal notification sound according to the sound environment. be able to.

In addition, you may change the said embodiment as follows.
As shown in FIG. 1, the illuminance sensor 51 may detect the illuminance as the surrounding environment.

  As shown in FIG. 1, an operation switch 52 may be provided as an operation unit that can be switched between sound notification and light notification by the user. In this case, the door ECU 10 selectively switches between sound notification and light notification based on the operation state (operation signal) of the operation switch 52. By changing in this way, the operation switch 52 can be used to switch between notification by sound and notification by light, and notification in a manner that matches the user's request can be performed. For example, as a situation where you do not want to make a sound, when you put a sleeping child (infant) on the vehicle (or remove it from the vehicle), you will be notified by sound regardless of the time zone, etc. It can be lost.

  In the embodiment, for example, when notification by sound is preferable depending on the door state (for example, a situation in which the notification time is long), the door ECU 10 does not select the drive of the buzzer 42, that is, does not perform notification by sound. It may be.

  In the embodiment, the door ECU 10 may control any attribute of the notification sound generated by the buzzer 42 or a combination thereof based on the detected sound environment. Note that “sound attributes” refer to sound volume (sound pressure, sound intensity), sound pitch (frequency), sound type (tone color, waveform of sound signal), and the like.

  In the above-described embodiment, the sound notification is performed in place of or in addition to the buzzer 42, for example, an arbitrary sound generator that can be recognized from the surroundings of the vehicle, such as a speaker or a horn built in the navigation system or the audio system, You may carry out in combination.

  In the above embodiment, the light notification is performed by using any lighting device that can be recognized from around the vehicle, such as a dome lamp (room lamp), a head lamp, a tail lamp, or a combination thereof, instead of or in addition to the LED 41. Also good.

In the embodiment, the timepiece 44 may be built in a navigation system, for example, or may be installed on a dashboard.
