[Description of Operation of First Embodiment]
Hereinafter, the operation of the driving posture adjusting apparatus according to the present embodiment will be described. In the present embodiment, when it is determined that the vehicle is automatically driven and the driver D1 intends to change the posture, the footrest movable mechanism 24 and the seat seat surface movable mechanism 28 are unlocked. Thus, the driver can extend the lower limbs.

  FIG. 3 is a flowchart illustrating a processing procedure performed by the driving posture adjusting apparatus according to the first embodiment. This process is executed by the controller 50 shown in FIG.

  First, in step S11 of FIG. 3, the controller 50 determines whether or not the vehicle 100 is currently traveling in automatic driving. If automatic operation is in progress (YES in step S11), the process proceeds to step S12. If automatic operation is not in progress (NO in step S11), the process proceeds to step S16.

  In step S12, the information presentation control unit 53 displays on the display unit 54 that the driving operation by the driver D1 is unnecessary, and informs the driver D1 of this content.

  In step S13, the posture change intention determination unit 51 determines whether the driver has an intention to change posture. Hereinafter, an example of determining the presence / absence of posture change will be described with reference to schematic diagrams shown in FIGS. 10 (a) to 10 (c) and FIGS. 11 (a) to 11 (c).

  In FIG. 10A, a load exceeding a predetermined value is detected by the load sensor 25 of the footrest portion 14, and the increase or decrease of the load detected by the seat seat surface load sensor 26 exceeds the predetermined value. In this case, it is determined that there is an intention to change the posture. For example, when the driving time is a long time, the driver D1 wants to extend his lower limbs or toes. In such a case, the load applied to the footrest 14 is inevitably increased. In addition, the load applied to the seat seat surface 11 changes. Therefore, in such a case, it is determined that there is an intention to change the posture.

  FIG. 10B shows a case where a load exceeding a predetermined value is detected by the load sensor 25 of the footrest 14 and the increase or decrease of the load detected by the seatback load sensor 27 exceeds the predetermined value. Then, it is determined that there is an intention to change the posture. In other words, when the driver D1 extends his / her back and tries to extend the toe, the load applied to the footrest portion inevitably increases and the load applied to the seat back 12 changes. Therefore, in such a case, it is determined that there is an intention to change the posture.

  FIG. 10C shows the case where two footrests 14 are provided for the left foot and the right foot, and the posture is changed when a load exceeding a predetermined value is simultaneously applied to the left and right footrests 14. Judge that there is a will. That is, since it can be determined that the driver D1 desires to extend the lower limb that a large load is applied simultaneously on the left and right, in such a case, it is determined that there is an intention to change the posture.

  FIG. 11A shows a case where two sensors (left seat seat load sensor, right seat seat load sensor) are provided on the left and right sides of the seat seat surface 11 and are detected by both sensors. When the load balance changes, it is determined that there is an intention to change the posture. For example, when the driver D1 seated on the seat seat surface 11 moves the center of gravity to either the left or right, the load of one seat surface load sensor increases and the load of the other seat surface load sensor decreases. To do. In such a case, it is determined that the driver D1 is trying to move the body, and it is determined that there is an intention to change the posture.

  FIG. 11B shows a case where two sensors (front seat seat load sensor, rear seat seat load sensor) are provided before and after the seat seat surface 11 and are detected by both sensors. When the load balance changes, it is determined that there is an intention to change the posture.

  FIG. 11C shows a case where two sensors (upper seat back load sensor and lower seat back load sensor) are provided above and below the seat back 12, and the load detected by both sensors is shown. When the balance changes, it is determined that there is an intention to change the posture. Specifically, when the difference between the upper load and the lower load is a positive value, it is determined that there is an intention to change the posture.

  And in this embodiment, when it will be in any one of above-mentioned FIG. 10 (a)-(c) and FIG. 11 (a)-(c), there exists an intention of the attitude | position change by driver | operator D1. Judge. Further, it may be input by the operation input by the input unit 55 that the driver has an intention to change the posture directly. As a result, YES is determined in the process of step S13 in FIG. 3, and the process proceeds to step S14.

  In step S <b> 14, the movable control unit 52 unlocks the footrest moving mechanism 24. As a result, the footrest part 14 can change the inclination angle with the heel position as a fulcrum. Further, the footrest portion 14 can be slid in the front-rear direction. Furthermore, it becomes possible to raise and lower the footrest portion 14 in the vertical direction.

  In step S15, the movable control unit 52 unlocks the seat seat surface movable mechanism 28. As a result, the seat seat surface 11 can change the inclination angle. And in addition to the change of the footrest part 14, by changing the inclination angle of the seat seating surface 11, as shown in FIG. 4, the driver D1 can incline the footrest part 14 using the symbol Q1 as a fulcrum. Since the seat seating surface 11 can be inclined downward, the lower limbs and the toe portion of the foot can be extended. As a result, the whole body can be stretched and stretched. That is, as shown in FIG. 5, during the automatic driving, the driver D1 can stretch the lower limbs and the toes.

  Further, as shown in FIG. 6, the footrest portion 14 is slid upward as shown in FIG. 6 (b) from the position shown in FIG. 6 (a) and the seat seat surface 11 is inclined upward. Can bend and stretch knees.

  Further, as shown in FIG. 7, the footrest portion 14 is slid forward from the position shown in FIG. 7 (a) as shown in FIG. 7 (b), and the front side of the seat seat surface 11 divided forward and backward By moving the seat seat surface 11b downward, the knee can bend and stretch.

  Thereafter, when the automatic operation is finished in step S11 (NO in step S11), in step S16, the controller 50 determines whether the footrest movable mechanism 24 and the seat seat surface movable mechanism 28 are unlocked. Judge whether or not.

  If unlocked (YES in step S16), in step S17, the controller 50 locks the footrest movable mechanism 24 and the seat seat surface movable mechanism 28 and returns them to a state suitable for driving operation. . In this way, the driver D1 can immediately perform the driving operation while taking the driving posture of the vehicle.
