The driver circuit uses, for example, an active matrix driving method in which a transistor is attached to each pixel so that the target pixel can be reliably turned on and off, and is based on a display command and display screen data sent from the control circuit 80. To display. Moreover, you may use an organic EL (ElectroLuminescence: electroluminescence) display and a plasma display as a display device. The display unit 21 corresponds to the restricted mode information output unit of the present invention.

  The speaker 23 is connected to a well-known voice synthesis circuit 22 and the digital voice data stored in the memory 90 in accordance with a command from a control program 82p (described later) is converted into analog voice by the voice synthesis circuit 22 and sent out. Note that speech synthesis methods include a recording / editing method in which speech waveforms are stored as they are or after being encoded and connected as necessary, and a text synthesis method in which corresponding speech is synthesized from character input information.

  The slide door opening / closing drive unit 24 is for performing drive control of the motor 25 for automatically opening / closing the slide door 26 based on an opening / closing control command from the control circuit 80, and includes a known motor drive circuit and the like. Is done. The sliding door opening / closing drive unit 24 and the motor 25 correspond to the automatic opening / closing drive means of the present invention.

  The control circuit 80 includes a well-known CPU 81, ROM 82, RAM 83, input / output circuit I / O 84, A / D converter 86, communication I / F (interface) 87, memory 90, and a bus for connecting these components. A line 85 is provided. The CPU 81 performs control based on the control program 82p and data stored in the ROM 82. The control circuit 80 corresponds to the set value update means of the present invention.

  The A / D conversion unit 86 includes a well-known A / D (analog / digital) conversion circuit, and converts analog data input to the control circuit 80 from the above-described various sensors into digital data that can be calculated by the CPU 81, for example. It is.

  The communication I / F 87 is a communication interface circuit such as a LAN (Local Area Network) card for exchanging data with other in-vehicle devices.

  As the memory 90, an electrically rewritable semiconductor storage medium such as a flash memory or a hard disk device is used, and information and data necessary for the operation of the slide door device 100 are stored. Note that the memory 90 holds the stored contents even when the sliding door device 100 is turned off. The memory 90 corresponds to the target door opening setting storage means of the present invention.

  As shown in FIG. 2, the inner switch 31 (31a, 31b) and the outer switch 32 (32a, 32b) are disposed inside and outside the vehicle 101, respectively, and are used to manually open and close the slide door 26. For example, the slide door 26 moves in the closing direction while pressing 31a and 32a, and the slide door 26 moves in the opening direction while pressing 31b and 32b. The inner switch 31 and the outer switch 32 correspond to the restriction mode door opening change setting means of the present invention.

  The automatic opening / closing switch 33 is used for automatically opening / closing the sliding door 26 in the restriction mode of the present invention (details will be described later). The automatic opening / closing switch 33 corresponds to the opening / closing operation unit of the present invention. The automatic opening / closing switch 33 is installed in the driver's seat and the passenger seat (that is, the front seat). Further, the automatic switch 33 may be included in the outer switch 32 at the front of the vehicle 101.

  The mode changeover switch 34 is for switching between a normal mode in which the slide door 26 can be fully opened and a restriction mode in which the target door opening during the opening operation is set smaller than the normal mode. A seesaw switch or a push switch with a lock is used. When the mode changeover switch 34 is in the on state, the limit door mode is set in which the target door opening during the opening operation is set smaller than that in the normal mode. On the other hand, when the mode changeover switch 34 is in the OFF state, the normal mode is set in which the sliding door 26 can be fully opened. The mode changeover switch 34 is installed only in the driver's seat and the passenger seat (that is, the front seat). The mode changeover switch 34 corresponds to the opening / closing operation enabling means, automatic opening / closing drive mode setting means, and restriction mode releasing means of the present invention.

  The slide door position sensor 36 is for detecting the position of the slide door 26. The slide door position sensor 36 includes, for example, a rotation detection unit such as a known rotary encoder or resolver that detects the number of rotations of the motor 25. The moving distance of the slide door 26 when the motor 25 rotates once is determined in advance by the configuration of the moving mechanism (not shown) of the slide door 26. That is, assuming that the fully closed position of the slide door 26 is a reference point, the current position of the slide door 26 can be obtained by measuring the number of rotations of the motor 25 from the reference point.

  The shift position sensor 11 detects the position of a shift lever (not shown) or a transmission gear (not shown). A switch is provided for each position of the shift lever or gear, and the state of the switch changes according to the position of the shift lever or gear of the vehicle 101. In the case of vehicles equipped with automatic transmissions, the current shift position is lit and displayed near the instrument panel of the driver's seat or the shift lever, so the current shift position is identified by detecting the lit position. You may use the method to do.

  The vehicle speed sensor 12 includes a rotation detection unit such as a known rotary encoder, and is installed near the wheel mounting unit, for example, to detect the rotation of the wheel and send it to the control circuit 80 as a pulse signal. In the control circuit 80, the rotational speed of the wheel is converted into the speed of the vehicle 101.

  The rain sensor 13 is for detecting the amount of rainfall and includes a piezoelectric element. For example, as shown in FIG. 3, the vehicle 101 is attached near the opening 26 a formed when the slide door 26 is in an open state.

  The wiper switch 14 is used to instruct a wiper drive, and is attached to the steering column as a lever switch, for example, as shown in FIG. The wiper switch 14 can select, for example, four operation modes of OFF, INT (intermittent operation), Lo (low speed operation), and Hi (high speed operation), and wiper drive control is performed according to the operation mode. Is called. The wiper switch 14 corresponds to the ambient state information acquisition unit and the rainfall state detection unit of the present invention.

  The obstacle sensor 15 is for specifying whether or not there is an object that hinders getting on and off the vehicle as shown in FIG. For example, non-contact type object detection such as a known phased array radar, a sonar used to detect obstacles around the vehicle, or a light-reflective photo interrupter in which a light emitting unit and a light receiving unit are integrated. Means are used and are mounted near the entrance. The distance between the vehicle and the object is measured, and it is determined whether or not the distance is a value capable of getting on and off. For example, when the obstacle is a guardrail, the distance between the vehicle and the guardrail is measured, and it is determined that it is possible to get on and off when a predetermined threshold value such as 75 cm is exceeded. The obstacle sensor 15 corresponds to the obstacle specifying means of the present invention.

  The room temperature sensor 16 and the outside air temperature sensor 17 include a known thermistor and thermocouple. For example, as shown in FIG. 2, the room temperature sensor 16 is attached to a position where it is difficult to receive direct sunlight from the center console. In the case of an air conditioner-equipped vehicle, a temperature sensor used for air conditioner operation control may also be used. For example, as shown in FIG. 2, the outside air temperature sensor 17 is attached to a place where the heat of the engine is difficult to stay, such as behind the front grill of the engine room of the vehicle 101. When engine rotation control is performed based on the outside air temperature, the outside air temperature sensor may also be used. The room temperature sensor 16 corresponds to the ambient state information acquisition means and vehicle interior temperature detection means of the present invention, and the outside air temperature sensor 17 corresponds to the ambient state information acquisition means and vehicle exterior temperature detection means of the present invention.

  The sliding door automatic opening / closing main process will be described with reference to FIG. This process is included in the control program 82p and is repeatedly executed together with other processes of the control program 82p. First, information on the switches (inner switch 31, outer switch 32, automatic opening / closing switch 33, mode changeover switch 34) related to the opening / closing operation of the slide door 26 is acquired (S11).

  When it is detected that a switch operation related to the opening / closing operation of the sliding door 26 is performed (S12: Yes), a sliding door operation permission determining process for determining whether the opening / closing operation of the sliding door 26 is permitted is performed. Execute (S13, described later).

  When it is determined that the opening / closing operation of the slide door 26 is permitted (S14: Yes) and the automatic opening / closing switch 33 is operated (S15: Yes), the state of the mode switch 34 is checked. When the mode switch 34 is in the on state, that is, the restriction mode (S16: Yes), an automatic opening / closing operation process for automatically opening / closing the sliding door 26 is executed (S17, described later). Details of the subsequent target door opening update setting process (S18) will be described later.

  The sliding door operation permission determination process corresponding to step S13 in FIG. 4 will be described with reference to FIG. First, vehicle speed information is acquired from the vehicle speed sensor 12 (S31). For example, when the vehicle speed is 0 km / h (S32: Yes), it is determined that the vehicle 101 is stopped, and shift position information is acquired from the shift position sensor 11 (S33).

  When the shift position is “parking” (S34: Yes), the obstacle information is acquired from the obstacle sensor 15 (S35). When there is no obstacle that hinders getting on and off around the slide door 26 (S36: Yes), the opening / closing operation of the slide door 26 is permitted (S37). This permission information can be referred to in other processes by setting an opening / closing operation permission flag that secures an area in the RAM 83, for example.

  On the other hand, when the vehicle 101 is not stopped (S32: No), when the shift position is not “parking” (S34: No), or when there is an obstacle around the slide door 26 (S36: No), the slide door 26 is not permitted (S38). At this time, the opening / closing operation permission flag is cleared.

  In addition, it is good also as a structure which does not include the presence or absence of an obstruction in the conditions of opening / closing operation permission. In this case, steps S35 and S36 are skipped.

The automatic opening / closing operation process corresponding to step S17 in FIG. 4 will be described with reference to FIGS. First, ambient state information reflecting the ambient state of the vehicle is acquired (S51). Next, a target door opening is set based on the acquired ambient state information (S52). The target door opening is set using one or more of the following.
(1) The target door opening is set based on the amount of water droplets detected by the rain sensor 13 (that is, the amount of rainfall). The relationship between the amount of rainfall and the target door opening is expressed as shown in FIG. 7, for example. Based on this relationship, the target door opening is obtained from a data table or a calculation formula stored in advance in the memory 90. In the example of FIG. 7, the ratio to the rainfall amount that sets the target door opening degree to “fully closed” is used as a parameter.
(2) The target door opening is set based on the position of the wiper switch 14. The relationship between the position of the wiper switch 14 and the target door opening is expressed as shown in FIG. 8, for example. This relationship is stored in the memory 90 in advance.
(3) The target door opening is set based on the temperature difference between the inside air temperature and the outside air temperature measured by the room temperature sensor 16 and the outside air temperature sensor 17. The relationship between the temperature difference and the target door opening is expressed as shown in FIG. 9, for example. Based on this relationship, the target door opening is obtained from a data table or a calculation formula stored in advance in the memory 90.

  In the example of FIG. 7 (the same applies to FIG. 9), if the relationship between the rainfall up to now and the target door opening is approximated by a straight line A (that is, a linear function), the rainfall is substituted into the linear function. The target door opening can be calculated.

  Returning to FIG. 6, based on the set target door opening, a command is sent from the control circuit 80 to the sliding door opening / closing drive unit 24, and the sliding door 26 is opened (S53). At this time, the display unit 21 displays that the automatic opening / closing operation of the slide door 26 is being performed in the restriction mode.

  FIGS. 11 to 13 show display examples of the display unit 21. FIG. 11 shows a display example when the automatic open / close switch is operated when the peripheral state information is acquired using the rain sensor 13. The fact that it is the restriction mode and the opening degree of the slide door 26 are displayed. The target door opening of the left and right sliding doors can be set differently depending on how the rain falls.

  FIG. 12 shows a display example when the automatic open / close switch is operated when the peripheral state information is acquired using the wiper switch 14. The fact that it is the restriction mode and the opening degree of the slide door 26 are displayed. In this case, the target door openings of the left and right sliding doors are the same.

  FIG. 13 shows a display example when an obstacle that prevents getting in and out is detected around the slide door 26 on the side to be opened in the restriction mode. In this case, the state of the slide door on the opposite side may be displayed.

  In addition, the message displayed on the display unit 21 in FIGS. 11 to 13 may be output from the speaker 23 as a voice message. Text data that is the basis of the voice message is stored in the memory 90 in advance.

  Returning to FIG. 6, the sliding door position information is acquired from the sliding door position sensor 36 (S54). When the sliding door 26 moves to the position set by the target door opening degree (S55: Yes), an automatic opening / closing operation flag that secures an area is set in the RAM 83 (S60), and the sliding door opening / closing drive is performed from the control circuit 80. A command is sent to the unit 24, and the opening operation of the slide door 26 is stopped (S59).

  On the other hand, when the slide door 26 has not moved to the position set by the target door opening degree (S55: No), the switch information related to the opening / closing operation of the slide door 26 is acquired (S56). When an operation such as the inner switch 31 or the outer switch 32 that is not related to automatic opening / closing is performed, or when the mode change switch 34 is turned off and the restriction mode is released (S57: Yes), the target The door opening is set as the current door opening and stored in the memory 90 in association with the acquired ambient state information (S58). FIG. 14 shows a display example on the display unit 21 at this time. Thereafter, a command is sent from the control circuit 80 to the slide door opening / closing drive unit 24, and the opening operation of the slide door 26 is stopped (S59).

  When the restriction mode is canceled, the target door opening degree may not be changed.

  In the example of FIG. 7 (the same applies to FIG. 9), when the slide door 26 is stopped at a position different from the target door opening by the operation of another switch by the user, the current slide door 26 is opened as indicated by a cross. The degree is stored as the target door opening together with the rainfall. The calculation of the target door opening from the next time is performed not by the straight line A but by a newly approximated straight line B (primary function).

  Further, in the example of FIG. 8, when the position of the wiper switch 14 is INT, the target door opening degree of the sliding door 26 is ½ of the fully opened position, but the opening degree of the sliding door 26 is 1/2 of the fully opened position. When another switch is operated at the position of 3, the target door opening in the case of INT is updated to 1/3 of the fully opened state.

  After the sliding door 26 is automatically opened and closed, the opening position of the sliding door 26 may be changed to achieve a new target door opening. The target door opening update setting process corresponding to step S18 of FIG. 4 will be described with reference to FIG. First, when the automatic opening / closing operation flag is set (S71: Yes), the automatic opening / closing operation flag is cleared (S72), and the timer is started (S73).

  Next, slide door position information is acquired from the slide door position sensor 36 (S74). Then, when the inner switch 31 or the outer switch 32 is operated and the position of the slide door 26 is changed from the position where it was stopped in the automatic opening / closing operation process previously executed (S75: Yes), the ambient state information is acquired (S76). ). Then, the current door opening (the position of the slide door 26) is set as the target door opening, and stored in the memory 90 in association with the acquired ambient state information (S77). FIG. 15 shows a display example on the display unit 21 at this time.

  Returning to FIG. 10, when the predetermined time has not elapsed (S78: No), switch information relating to the opening / closing operation of the slide door 26 is acquired (S79). Then, when a switch operation is performed such that the mode changeover switch 34 is turned off and the restriction mode is released (S80: Yes), this process ends.

  On the other hand, when the predetermined time has elapsed (S78: Yes), this process ends.

  Although the embodiments of the present invention have been described above, these are merely examples, and the present invention is not limited to these embodiments, and the knowledge of those skilled in the art can be used without departing from the spirit of the claims. Various modifications based on this are possible.
