  Although not shown, the seat seat 11A of the passenger seat is provided with a seat seat operating means 22 according to FIG. 3 on the left side (the back side of the paper) of the seating portion (12), and the seat selection operation portion Except for the point that 30 and the first to fourth proximity sensors 41 to 44 are omitted, the other configurations are the same as the configuration of the seat 11.

Next, based on the block circuit diagram of FIG. 4, a control system for performing posture adjustment of the seats 11 and 11A configured as described above will be described.
As shown in FIG. 4, the driver's seat ECU 51, the passenger seat ECU 52, and the in-vehicle ECU 53 are electrically connected to the system bus BUS, and communication between the ECUs 51 to 53 is possible. Each of the ECUs 51 to 53 includes, for example, a CPU, a ROM, a RAM, an EEPROM, and the like, and is configured to execute a program for realizing a function for each of the ECUs 51 to 53.

  The driver's seat ECU 51 has a function of controlling various postures of the driver's seat 11. The ECU 51 is connected to the motors 14, 16, 18, and 20, and the slide switch 23, lifter switch 24, tilt switch 25, and reclining switch 27. The ECU 51 is connected to the above-described seat selection switch 29, posture set switch 31, first and second posture designation switches 32 and 33, and first to fourth proximity sensors 41 to 44. ing.

  For example, when an operation signal in a corresponding operation direction is output from the slide switch 23 by the operation of the movement operation unit 26, the ECU 51 controls the drive of the first drive mechanism 15 correspondingly. As a result, the seat 12 of the driver's seat 11 moves in the front-rear direction (in the direction of arrow F1 shown in FIG. 2). When an operation signal in a corresponding operation direction is output from the lifter switch 24 by the operation of the moving operation unit 26, the ECU 51 controls the second drive mechanism 17 correspondingly. Thereby, the seating part 12 of the seat 11 moves in the vertical direction (the direction of arrow F2 in FIG. 2). When an operation signal in a corresponding operation direction is output from the tilt switch 25 by the operation of the moving operation unit 26, the ECU 51 controls the third drive mechanism 19 correspondingly. Thereby, the front-end part of the seating part 12 of the seat 11 is tilted up and down (arrow F3 direction of FIG. 2). Further, when an operation signal in a corresponding operation direction is output from the reclining switch 27 by the operation of the tilt operation unit 28, the ECU 51 controls the drive of the fourth drive mechanism 21 correspondingly. Thereby, the backrest 13 of the seat 11 is tilted in the front-rear direction (the direction of arrow F4 in FIG. 2).

  After the set operation unit 34 illustrated in FIG. 3 is operated and an operation signal that is once turned on is output from the posture set switch 31 illustrated in FIG. 4, the first posture designation operation unit 35 is continuously operated to perform the first posture. When an operation signal that is once turned on is output from the designation switch 32, the ECU 51 stores the current posture of the seat 11 in the storage means 54 as the first posture (position). Further, after the set operation unit 34 is operated and an operation signal that is once turned on is output from the posture set switch 31 shown in FIG. 4, the second posture designation operation unit 36 is continuously operated to perform the second posture. When an operation signal that is once turned on is output from the designation switch 33, the ECU 51 stores the current posture of the seat 11 in the storage means 54 as the second posture (position). For example, after the posture of the seat 11 is arbitrarily adjusted, when the first posture designation switch 32 or the second posture designation switch 33 is operated alone and the aforementioned operation signal is output, the ECU 51 First to fourth drive mechanisms for returning the posture of the seat 11 to the first posture or the second posture based on the data of the first posture or the second posture stored in the storage means 54. 15, 17, 19, and 21 are drive-controlled.

  In FIG. 4, for example, in a state where the position adjustment target is selected by the seat selection switch 29 to the seat 11 of the driver's seat, the ECU 51 receives the operation signals from the switches 23 to 25 and 27 of the seat seat operating means 22. Based on this, the corresponding drive mechanism (motors 14, 16, 18, 20) is driven and controlled. Thereby, the attitude | position of the seat seat 11 of a driver's seat is adjusted.

  On the other hand, a slide motor 14A, a lift motor 16A, a tilt motor 18A, and a tilt motor 20A similar to the motors 14, 16, 18, and 20 connected to the driver seat ECU 51 are connected to the passenger seat ECU 52. . Then, in a state where the posture adjustment target is selected for the passenger seat 11 </ b> A by the seat selection switch 29, the ECU 51 is based on the operation signals from the switches 23 to 25 and 27 of the seat seat operating means 22. A command signal is output to the passenger seat ECU 52 via the BUS in order to drive and control the corresponding driving mechanism (motors 14A, 16A, 18A, 20A) on the passenger seat side. The passenger seat ECU 52 receives the command signal and controls the driving mechanism (motors 14A, 16A, 18A, 20A) on the corresponding passenger seat side. As a result, the posture of the passenger seat 11A is adjusted.

  The passenger seat ECU 52 includes a slide switch 23A, a lift switch 24A, a tilt switch 25A, and a reclining that are the same as the slide switch 23, lifter switch 24, tilt switch 25, and reclining switch 27 connected to the driver seat ECU 51. A switch 27A is connected. The passenger seat ECU 52 controls driving of the corresponding drive mechanism (motors 14A, 16A, 18A, 20A) based on the operation signals from the switches 23A to 25A, 27A regardless of the operation state of the seat selection operation unit 30. It is supposed to be. As a result, the posture of the passenger seat 11A is adjusted.

  A display means 55 and a speaker 56 installed in the vehicle (for example, a center console) are connected to the vehicle ECU 53. As the display means 55, for example, a display such as an LCD, LED, EL, or plasma is used to display the seats 11, 11 </ b> A whose posture is to be adjusted and other information. As the in-vehicle ECU 53, the display unit 55, and the speaker 56, for example, the ECU, the display unit, and the speaker of the navigation system may be shared.

Next, various functions for executing the present invention provided in the driver seat ECU 51 of FIG. 4 will be described.
As shown in FIG. 1, on the screen 57 of the display means 55, a first display area 57A for displaying a three-dimensional image (perspective view) of the seat 11 and other images and various character information, the seat seat operation Images of each operation unit having the same shape as the front shape of the moving operation unit 26, the tilt operation unit 28, the sheet selection operation unit 30, the set operation unit 34, and the first and second attitude designation operation units 35 and 36 of the means 22 , Defined as switch images 26G, 28G, 30G, and 34G to 36G), a second display area 57B is provided. In each of the switch images 26G, 28G, 30G, and 34G to 36G, a white arrow that suggests a posture adjustment direction, character information, and the like are also drawn as function information. Further, in the upper corner of the first display area 57A, the seat selected by the seat selection switch 29 (driver seat seat 11 or passenger seat seat 11A) is set as “driver seat” or “passenger seat”. A third display area 57C for displaying characters is provided. In the storage means 54, data of the various switch images 26G, 28G, 30G, 34G to 36G and data such as various animations are stored in advance.

  As shown in FIG. 4, the driver seat ECU 51 is provided with display control means 61. The display control unit 61 is provided with a switch image display unit 62. The switch image display unit 62 has the following functions. That is, in FIG. 3, when the operator's finger approaches one of the operation units 26, 28, 30, 34, 35, 36, the operation corresponding to the operator's finger is performed by the proximity sensors 41 to 44. It is detected that the part is approaching. Based on the detection signal of the proximity sensor, the switch image display unit 62 reads the various switch image data stored in the storage unit 54 in advance, and switches images 26G and 28G in the second display area 57B of the display unit 55. , 30G, 34G-36G.

  Further, the display control means 61 is provided with a switch selection display section 63 as an area information display section for displaying a specific switch image among the switch images 26G, 28G, 30G, 34G to 36G so as to be selectable. . The switch selection display unit 63 functions as follows. That is, in FIG. 3, for example, when the operator's finger approaches the sheet selection operation unit 30 for the sheet selection switch 29, the operator's finger approaches the selection operation unit 30 by the third proximity sensor 43. Is detected. Based on the detection signal of the proximity sensor 43, the switch selection display unit 63 reads out the colored portion data stored in the storage means 54 in advance, and the outer periphery of the switch image 30G displayed in the second display area 57B shown in FIG. The ring-shaped coloring part 65 as area information is displayed on the part. Then, by this coloring unit 65, among the various switch images 26G, 28G, 30G, and 34G to 36G displayed in the second display area 57B, the switch image 30G corresponding to the sheet selection operation unit 30 that the operator is trying to operate. Is easily discriminated in comparison with other switch images. When a plurality of proximity sensors among the first to fourth proximity sensors 41 to 44 are detected and operated simultaneously, the colored portions 65 are respectively displayed on the corresponding switch images.

  (Definition) In this specification, the “area information” means information for distinguishing the specific switch image 30G from the other switch images 26G, 28G, and 34G to 36G as in the coloring portion 65 described above. As this "area information", only the switch image corresponding to the switch to be operated among the switch images other than the coloring unit 65 is displayed with high luminance, and other switch images are displayed with low luminance. In addition, there are various sort display information different from the normal switch image, such as displaying character information on the switch image. Also, image information that displays the position of the operator's hand in a pseudo manner according to the detection state of the hardware switch, specifically, the operator's hand shape is superimposed on the switch image like a mouse cursor on a personal computer. There is image information to be displayed together. Further, the display control means 61 is provided with an animation display section 66. The animation display unit 66 has the following functions. That is, in the storage means 54, the seat seat 11 of the driver's seat (or the passenger seat) to be operated from the three-dimensional overhead image representing the entire vehicle shown in FIG. A series of animation data up to a three-dimensional close-up image of the seat 11A is stored in advance. In FIG. 3, for example, an operator's finger approaches one of the operation units 26, 28, 30, 34 to 36 of the seat 11 of the driver's seat, and the corresponding proximity sensors 41 to 44 are used. When the approach of a finger is detected, based on the detection signal of the proximity sensor, the animation display unit 66 first causes the indoor ECU 53 to notify that the animation display operation is performed from the sound of the speaker 56. Through the speaker 56. Subsequently, the animation display unit 66 reads animation data stored in advance in the storage means 54. The animation display unit 66 displays an animation in the first display area 57A based on the read data. As a result of the above processing by the animation display unit 66, a three-dimensional seat seat image 11G, for example, a close-up of the seat seat 11 of the driver's seat, which is about to be operated as shown in FIG. 1, is finally displayed as a still image. .

Next, the control mode by the driver's seat ECU 51 will be described with reference to the flowchart of FIG.
First, in the initial screen state in which nothing is displayed in the first to third display areas 57A, 57B, and 57C of the display means 55 shown in FIG. 1 (or information related to the seat seat posture adjustment is not displayed). 6, whether or not the operator's fingers have approached the operation units 26, 28, 30, 34 to 36 of the hardware switches (23 to 25, 27, 29, 31 to 33) is first determined. To be determined by detection signals of the fourth proximity sensors 41 to 44. If it is detected by the corresponding proximity sensor (third proximity sensor 43) that the finger of the operator of the seat 11 has approached one of the operation units (here, the seat selection operation unit 30), YES is determined in step S1. The following processing is performed. That is, the switch image data is read from the storage means 54 by the function of the switch image display section 62 of the display control means 61 shown in FIG. 4, and the switch images 26G, 28G are displayed in the second display area 57B shown in FIG. , 30G, 34G to 36G are displayed in a layout. In synchronization with this, in step S3, the coloring unit 65 is displayed on the outer periphery of the switch image (switch image 30G) corresponding to the corresponding operation unit (sheet selection operation unit 30) by the function of the sorting display unit 63. The Therefore, the coloring unit 65 indicates which hardware switch the operator is trying to operate by visually observing the display of each switch image 26G, 28G, 30G, 34G to 36G in the second display area 57B shown in FIG. Can be easily grasped.

  Next, in step S4, when the operator actually operates the sheet selection operation unit 30 shown in FIG. 3, an operation signal is output from the corresponding sheet selection switch 29. At this time, when the operation target is selected as the passenger seat 11A (motors 14A, 16A, 18A, 20A) in the initial state, the driver seat seat 11 (motors 14, 16, 18, 20) is selected. And the characters “driver's seat” are displayed in the third display area 57C. At this time, the driver's seat ECU 51 recognizes the operation signals from the switches 23 to 25 and 27 as those on the driver's seat side and drives and controls the corresponding drive mechanisms (motors 14, 16, 18, and 20). . On the other hand, when the driver's seat 11 is selected as the operation target in the initial state, the seat is switched to the passenger seat 11A, and the characters “passenger seat” are displayed in the third display area 57C. In FIG. 1, the characters “driver's seat” are displayed in the third display area 57C by the process of step S5. At this time, the driver seat ECU 51 recognizes the operation signals from the switches 23 to 25 and 27 as those on the passenger seat side, outputs a command signal to the passenger seat ECU 52, and passes through the passenger seat ECU 52. Corresponding drive mechanisms (motors 14A, 16A, 18A, 20A) are controlled.

  Further, in synchronism with the above-described operation, in step S6, the function of the animation display unit 66 notifies the user that the animation is displayed in the first display area 57A of the screen 57 by sound output from the speaker 56.
