[First embodiment]
(Configuration of driving posture maintenance system)
FIG. 1 is a schematic diagram of a driving posture maintaining system according to a first embodiment of the present invention, and FIG. 2 is a schematic diagram showing a configuration of an instrument panel module according to the first embodiment of the present invention. . For example, the driving posture maintenance system 1 directs the direction of the seat in the traveling direction of the vehicle based on the road conditions and the like, and substantially matches the driving direction of the driver with the direction of the driver's body. Is to stabilize.

  As shown in FIGS. 1 and 2, the driving posture maintaining system 1 mainly includes an instrument panel module 14 as a module in which a seat 10 provided in a vehicle is movable and a steering 12 is provided at a position facing the seat 10. A steering angle detector 16 as a detector for detecting the steering angle of the steering wheel 12, and the steering angle of the steering wheel 12 is acquired from the steering angle detector 16, and the traveling direction of the vehicle is calculated based on the acquired steering angle. And a control unit 20 (to be described later) that calculates the amount of movement of the seat 10 based on the calculated traveling direction of the vehicle and controls the movement of the seat 10 and the instrument panel module 14 based on the calculated amount of movement of the seat 10.

Are generally configured. For example, the seat 10 rotates around a rotation axis 10B passing through a rotation center 10A that is substantially the center of the seat 100. The direction of the seat 10 is, for example, the line-of-sight direction when the driver is seated on the seat 10 and the driver faces the front. Assume that the seat 10 can be moved back and forth and rotated independently of the instrument panel module 14. The seat 10 may be configured to move integrally with the instrument panel module 14.

  The steering 12 is configured such that the traveling direction of the vehicle can be changed by a steer-by-wire system. This steer-by-wire system is different from a system in which a rotation operation with respect to the steering is mechanically converted to change the direction of the vehicle wheel, that is, the traveling direction of the vehicle, and is based on, for example, the steering angle of the steering 12 detected by a sensor or the like. The direction of the wheel of the vehicle is changed, and the direction of the wheel is changed via an actuator such as a motor. By adopting the steer-by-wire system, it is not necessary to mechanically connect the steering wheel 12 and the vehicle wheel, so that the steering wheel 12 can be laid out freely.

The steering angle detector 16 is configured to detect the rotation angle of the steering shaft 120 connected to the steering 12. As shown in FIG. 2, the steering shaft 120 is rotatably supported by the instrument panel module 14 by a support portion 121 provided on the inner wall 142 of the inclined portion 141.

  For example, the movable floor 30 is configured to move up and down by an instrument panel up / down actuator 186 described later. The movable floor 30 may be fixed to the vehicle. In this case, an opening is provided in the floor 31 corresponding to the rack 183, and the instrument panel module 14 moves up and down via the rack 183.

  The drive unit 18 as a module drive unit is provided in the instrument panel module 14 as shown in FIG. The drive unit 18 is configured to move the shaft 180 forward and backward by the control of the shaft 180 rotatably supported by the rotation support units 145 and 146 provided on the inner walls 143 and 144 opposed to the instrument panel module 14, respectively.

  The rack 183 has, for example, an arc shape, is provided on the movable floor 30, and is configured to move up and down integrally with the movable floor 30 via an instrument panel up / down actuator 186.

  FIG. 3 is a configuration block diagram of the driving posture maintaining system according to the first embodiment of the present invention. As shown in FIG. 3, the control unit 20 of the driving posture maintaining system 1 includes a steering angle detection unit 16, a seat position detection unit 103, a seat actuator 104 as a seat drive unit, an instrument panel left / right actuator 181, The instrument panel left / right position detection unit 184, the instrument panel vertical position detection unit 185, the instrument panel vertical actuator 186, the shift position detection unit 300, the vehicle speed detection unit 301, and the navigation device 302 are connected.

  The control unit 20 is a microcomputer including a CPU (Central Processing Unit) and a memory, for example.

  The seat position detection unit 103 is disposed, for example, on each of the seat 100, the backrest 101, and the headrest 102, and detects the front and rear position and rotation position of the seat 10 with respect to the instrument panel module 14, and the angle of the backrest 101 and the headrest 102 of the seat 10. It is schematically configured including a sensor.

  For example, the seat actuator 104 is disposed on each of the seat portion 100, the backrest 101, and the headrest 102, and adjusts the front-rear position and the rotational position of the seat 10 with respect to the instrument panel module 14, and the angle of the backrest 101 and the headrest 102 of the seat 10.

  The navigation device 302 includes, for example, a GPS (Global Positioning System), calculates a vehicle position based on radio waves from a plurality of satellites, and shows the current vehicle position on a map displayed on the display unit. is there.

  Hereinafter, the operation of the driving posture maintaining system according to the present embodiment will be described with reference to the drawings. First, the operation when traveling on the right curve will be described. The movement of the seat 10 and the instrument panel module 14 when traveling on the left curve is calculated by the same method as when traveling on the right curve, but the movement direction is reversed.

(Operation on the right curve)
FIG. 4 (a) is a schematic diagram inside the vehicle when traveling straight according to the first embodiment of the present invention, and FIG. 4 (b) is a schematic diagram inside the vehicle when traveling on the right curve. First, the operation of the driving posture maintenance system when shifting from the straight traveling state shown in FIG. 4A to the state of traveling on the right curve will be described. Here, the “body direction” shown in FIGS. 4A and 4B is the direction of the line of sight when facing the front in a state of being seated on the seat 100, and the “line of sight” is the driving direction. The “vehicle traveling direction” is the direction in which the vehicle 3 travels in the same direction as the direction of the wheels 31. Further, the wheel 31 is rotatably supported by, for example, a shaft 32, and the direction of the wheel 31 is determined via an actuator (not shown) and the shaft 32 based on the steering angle of the steering wheel 12 detected by the steering angle detection unit 16. Can be changed.

  As shown in FIG. 4A, when the vehicle 3 is in a straight traveling state, the direction of the driver's body, the line-of-sight direction, and the vehicle traveling direction are substantially the same, and the driver must drive in a stable driving posture. Can do. However, for example, when driving on a right curve, the driver operates the steering wheel 12 with the line-of-sight direction directed to the right side. At this time, the driver's head is tilted to the right with respect to the body, the driver's body direction and line-of-sight direction are different, and the driver's driving posture becomes unstable. The driver must drive on the right curve while the driving posture is unstable.

  The control unit 20 of the driving posture maintaining system 1 acquires the steering angle of the steering wheel 12 from the steering angle detection unit 16, and travels on the right curve when the acquired steering angle is rightward and larger than a certain angle. Is determined to have been started, the traveling direction of the vehicle 3 is calculated based on the acquired steering angle, an adjustment angle γ, which will be described later, is calculated as the amount of movement of the seat 10 based on the calculated traveling direction, and the calculated seat The seat actuator 104 and the instrument panel left / right actuator 181 of the drive unit 18 are controlled based on the adjustment angle γ of 10.

  Specifically, the instrument panel left / right actuator 181 rotates the pinion gear 182 in the same direction as the instrument panel left / right actuator 181 via the shaft 180 (clockwise as viewed from the driver side). The pinion gear 182 meshes with the rack 183, and the left-right direction of the rack 183 is fixed with respect to the vehicle 3. Therefore, the instrument panel module 14 is shown in FIG. 4B as the pinion gear 182 rotates. In this way, it moves to the right along the rack 183.

  Further, the seat 10 rotates in the same direction as the movement of the instrument panel module 14 by driving the seat actuator 104.

  The control unit 20 controls the instrument panel left / right actuator 181 based on the left / right position of the instrument panel module 14 obtained from the instrument panel left / right position detection unit 184 and the calculated movement amount. The control unit 20 controls the seat actuator 104 based on the calculated front and back position and rotation position of the seat 10 acquired from the seat position detection unit 103 and the calculated movement amount.

  FIG. 5 is a schematic diagram of the interior of the vehicle when traveling on a sharp right curve according to the first embodiment of the present invention. FIG. 5 shows a case where the direction of the seat 10 and the direction of the steering 13 integrated with the instrument panel module 14 are different. Since the seat 10 and the instrument panel module 14 are driven independently, for example, when traveling on a steep curve, it may be dangerous if the directions of the seat 10 and the instrument panel module 14 coincide. At that time, the control unit 10 drives the seat 10 and the instrument panel module 14 in opposite directions based on the amount of movement of the sheet 10 and controls the speed of movement. The movement of the seat 10 and the instrument panel module 14 is performed based on the adjustment angle γ calculated by the following method.

FIG. 6 is a schematic diagram regarding the vehicle speed and the maximum adjustment angle according to the first embodiment of the present invention, and FIG. 7 is a schematic diagram showing the relationship between the adjustment angle and the seat according to the first embodiment of the present invention. FIG. The maximum adjustment angle γ _max is the maximum value of the adjustment angle γ with respect to the vehicle speed V. Further, the adjustment angle γ is an angle formed by a straight line connecting the steering 12 and the rotation center 10A in a straight traveling state and a straight line connecting the steering 12 and the rotation center 10A after the instrument panel module 14 is moved. Note that the maximum adjustment angle γ _max shown in FIG. 6 decreases as the vehicle speed increases. This is because the large movement of the seat 10 during high-speed traveling is rather dangerous. In the following, calculation is performed for the case where the seat 10 and the instrument panel module 14 face the same direction.

For example, the control unit 20 calculates the adjustment angle γ using the following equation (1) based on the maximum adjustment angle γ _max at the vehicle speed V.
Adjustment angle γ = γ _max × steering angle θ / maximum steering angle θ _max (1)
Here, the steering angle θ is a rotation angle based on the steering 12 when traveling straight, and the maximum steering angle θ _max is, for example, an angle obtained by rotating the steering wheel 12 half a turn, that is, 900 °. Note that the steering angle θ is, for example, positive in the case of rightward operation and negative in the case of leftward operation. Therefore, the adjustment angle γ is an adjustment angle that moves the seat 10 and the instrument panel module 14 in the right direction when positive, and an adjustment angle that moves the seat 10 and the instrument panel module 14 in the left direction when negative.

Moreover, the position adjustment amount of the sheet | seat 10 and the instrument panel module 14 is represented by the following formula | equation (2), for example.
Position adjustment amount = 2πr × γ / 360 (2)
Here, as shown in FIG. 7, r is the distance from the portion closest to the driver of the steering wheel 12 to the rotation center 10A.

  The control unit 20 acquires the vehicle speed V from the vehicle speed detection unit 301, calculates the adjustment angle γ using the above equation (1), and adjusts the positions of the seat 10 and the instrument panel module 14 based on the calculated adjustment angle γ. To do. Note that when the vehicle 3 travels at a lower speed than, for example, a highway such as a traffic jam or an urban area, it is generally desirable that the vehicle traveling direction and the line-of-sight direction coincide with each other.

  Next, the control unit 20 continuously adjusts the positions of the seat 10 and the instrument panel module 14 based on the steering angle θ of the steering wheel 12 acquired from the steering angle detection unit 16, and when the vehicle 3 returns to the straight traveling state, The adjustment of the seat 10 and the instrument panel module 14 is finished.

(Operation at high speed)
Next, the operation of the driving posture maintenance system 1 when the vehicle 3 is traveling at high speed will be described.

  For example, when the vehicle 3 is traveling at a high speed, the driver's line of sight is narrowed, and it is known that the driver's line of sight is lowered in a direction closer to the front end of the vehicle 3, that is, lower than at a low speed. Yes. Therefore, the control unit 20 controls the instrument panel up / down actuator 186 to move the instrument panel module 14 downward. At this time, the control unit 20 controls the instrument panel vertical actuator 186 based on the vertical position of the instrument panel module 14 acquired from the instrument panel vertical position detection unit 185.

  The control unit 20 changes the driver's line of sight upward by controlling the vertical position of the instrument panel module 14 downward, so that the driver can ensure visibility.

  The control unit 20 may perform a combination of the operation for traveling on the right or left curve and the operation for traveling at a high speed. For example, the control unit 20 may adjust the vertical position together with the adjustment of the left and right positions of the seat 10, and may adjust the angles of the backrest 101 and the headrest 102. Further, the control unit 20 may drive the seat actuator 104 and move the steering 13 in the front-rear direction.

(Effects of the first embodiment)
According to the first embodiment of the present invention, the following effects can be obtained.
(1) Since the left and right positions of the seat 10 and the instrument panel module 14 can be adjusted based on the steering angle θ of the steering wheel 12, the driver can drive in a stable driving posture.
(2) Since the vertical position of the seat 10 and the instrument panel module 14 can be adjusted based on the speed of the vehicle 3, the driver can drive in a stable driving posture even during high-speed driving.
(3) Since the vehicle can be driven in a stable driving posture even when traveling on the right or left curve, the operability of the switch provided on the steering wheel 12 is improved.
(4) Since the seat 10 and the instrument panel module 14 are driven independently, the driver can drive in a more stable driving posture than when the seat 10 and the instrument panel module 14 move together. .

[Second Embodiment]
Hereinafter, a second embodiment of the present invention will be described with reference to the drawings. In the following description, the same components and parts as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and description thereof will be omitted. Further, the operation of moving the instrument panel module 14 is the same as that in the first embodiment, so that it will be omitted.

  The second embodiment is different from the first embodiment in that the seat and the instrument panel module are moved based on the driver's line-of-sight direction.

(Configuration of driving posture maintenance system)
FIG. 8 is a block diagram showing the configuration of the driving posture maintaining system according to the second embodiment of the present invention. As shown in FIG. 8, the driving posture maintenance system 1 includes a camera 210, an image processing unit 211, and a camera actuator 212 in addition to the configuration in the first embodiment.

  FIG. 9A is a schematic diagram of the interior of the vehicle when traveling straight according to the second embodiment of the present invention, and FIG. 9B is a schematic diagram of the interior of the vehicle when starting to travel on the right curve, (C) is a schematic view of the interior of the vehicle when traveling on a right curve. The camera 210 is made of, for example, a CCD (Charge Coupled Device), a CMOS (Complementary Metal Oxide Semiconductor), or the like, and is disposed on the column unit 24 as shown in FIG. The arrangement position of the camera 210 is not limited to that on the column unit 24, and may be a position where the driver's face is always included in the imaging range 213.

  The image processing unit 211 processes the image captured by the camera 210 and calculates the driver's line-of-sight direction.

  The camera actuator 212 is for driving the camera 210 in the vertical direction, for example. For example, when the ignition switch is turned on, the control unit 20 drives the camera actuator 212 up and down so that the driver's face is included in the image acquired via the camera 210 and the image processing unit 211. Adjust the position.

  Hereinafter, the operation of the driving posture maintaining system according to the second embodiment will be described with reference to the drawings.

(Operation)
FIG. 10 (a) is an image of the driver's face imaged when traveling straight according to the second embodiment of the present invention, and FIG. 10 (b) is a driver imaged when starting traveling on the right curve. (C) is an image of the driver's face after the seat position is adjusted while traveling on the right curve.

  First, when the vehicle 3 is in a straight traveling state, as shown in FIG. 9A, the vehicle traveling direction, the line-of-sight direction, and the body direction are the same. As shown in (a), the driver's face 215 is imaged in front. For example, the image processing unit 211 sets the reference line 217 in the image 214 with reference to the driver's nose 216, calculates the area ratio of the left and right faces based on the reference line 217, and calculates the calculated left and right face areas. When the ratio is close to 1: 1, it is determined that it is facing the front, and when the calculated left and right face area ratio is biased, the smaller one, for example, as shown in FIG. When the face area is smaller than the right face, it is determined that the face is facing right, that is, the line-of-sight direction is the right direction. In addition, the image processing unit 211 calculates the gaze direction in the vertical direction, for example, by calculating the displacement amount of the eye position with reference to the driver when traveling straight. Note that the method of calculating the driver's line-of-sight direction is not limited to the above, and may be performed by a known method such as template matching.

  Here, since it is also assumed that the driver instantaneously changes the line-of-sight direction, the image processing unit 211 calculates the line-of-sight direction only when the line-of-sight direction does not change for a certain period of time. Further, since it is also assumed that the driver looks aside, the control unit 20 compares the steering angle of the steering wheel 12 with the calculated line-of-sight direction, and determines that the driver is looking aside when the difference exceeds a predetermined value. The seat 10 and the instrument panel module 14 are not adjusted.

  Next, when the driver starts traveling on the right curve, the driver changes the line-of-sight direction to the right as shown in FIGS. 9B and 10B. At this time, the driver's body direction and line-of-sight direction are different, resulting in an unstable driving posture.

  The image processing unit 211 performs image processing on the image 214 captured by the camera 210, calculates the gaze direction of the driver by the above gaze direction calculation method, and outputs the calculation result to the control unit 20.

  The control unit 20 calculates the adjustment angle γ based on the input calculation result, drives the seat actuator 104 and the instrument panel left / right actuator 181 based on the adjustment angle γ, and moves the seat 10 and the instrument panel module 14. As a result of the movement of the seat 10 and the instrument panel module 14, the driver captures an image 214 of the face from the front of the driver by the camera 210 as shown in FIGS.

  The control unit 20 continuously adjusts the positions of the seat 10 and the instrument panel module 14 and ends the adjustment of the seat 10 and the instrument panel module 14 in the left-right direction when the vehicle 3 goes straight. Note that when the control unit 20 acquires the speed of the vehicle 3 from the vehicle speed detection unit 301 and determines that the speed of the vehicle 3 is high, the seat 10 and the instrument panel module 14 are the same as in the first embodiment. Adjust the vertical direction of.

(Effect of the second embodiment)
According to the second embodiment of the present invention, the following effects can be obtained.
Since the positions of the seat 10 and the instrument panel module 14 can be adjusted based on the driver's line-of-sight direction calculated based on the image 214 captured by the camera 210, the driver can drive in a stable driving posture. .

  The present invention is not limited to the above-described embodiments, and various modifications and combinations can be made without departing from or changing the technical idea of the present invention.

  In each of the above-described embodiments, for example, depending on the road condition such as a curve or a slope acquired from the navigation device 302, the adjustment angle calculated according to the steering angle of the steering 12, and / or the driver's line-of-sight direction. The positions of the seat 10 and the instrument panel module 14 may be adjusted based on the calculated adjustment angle.

  In each of the above-described embodiments, for example, the control unit 20 may adjust the positions of the seat 100, the backrest 101, and the headrest 102 of the seat 10 based on the calculated adjustment angle.

  In each of the above embodiments, for example, the control unit 20 may adjust the position of the seat 10 and the instrument panel module 14 based on the shift position acquired from the shift position detection unit 300. For example, when the shift position is in the reverse position (reverse), the adjustment angle is calculated in the same manner as described above, but the direction is reversed.

  In each of the above embodiments, for example, the driving posture maintenance system 1 may include a switch that stops use of the driving posture maintenance system 1, and may be configured to stop use by turning off the switch.

  In each of the above-described embodiments, the seat 10 and the instrument panel module 14 are driven independently. However, for example, the seat 10 and the instrument panel module 14 may be integrated via the connecting portion 22 or the like. When integrated, the drive unit 18 may be disposed on the seat 10 side.
