FIG. 7 is a diagram showing a map.
(A) is a figure which shows the map which set the relationship between a lateral acceleration and a frequency. The frequency Fg of the first tactile sensation presentation unit 32 with respect to the lateral acceleration y can be set. The frequency Fg increases in proportion to the lateral acceleration y. When the lateral acceleration y is 0, that is, when the vehicle 12 is traveling straight, the frequency Fg is 0.

  (B) is a figure which shows the map which set the relationship between a vehicle speed and a frequency. The frequency Fv of the tactile sense presenting means (see FIG. 14) with respect to the vehicle speed Vc can be set. The frequency Fv increases in proportion to the vehicle speed Vc. When the vehicle speed Vc is 0, the frequency Fv is 0.

  FIGS. 8A and 8B are diagrams for explaining the mechanism of the tactile sense presenting means when the steering wheel is turned in the vicinity of the straight traveling state. A curve 62 of the travel lane 61 is shown in the upper stage, the first tactile sense presenting means 32 of the vehicle state transmission device 11 is shown in the middle stage, and the right tactile sense presenting means 46 is developed in the lower stage and schematically shown. This will be described with reference to FIG.

Here, turning the steering wheel 21 in FIG. 1 to the left (counterclockwise) is positive, and turning the steering wheel 21 to the right (clockwise) is negative.
Further, the reference position of the steering wheel 21 when traveling straight is set to Bs (0 ° position), the position where the steering wheel 21 is turned 1/4 turn is set to the plus 90 ° position and the minus 90 ° position, and the steering wheel 21 is turned 1/2 turn. These positions are defined as a plus 180 ° position and a minus 180 ° position, and positions where the steering wheel 21 is turned 3/4 turn are designated as a plus 270 ° position (minus 90 ° position) and a minus 270 ° position (plus 90 ° position). The same applies to the case where the steering wheel 21 is turned once or more than once.
When traveling straight, the 3 o'clock position 45 coincides with the reference position Bs (0 ° position).

  “When turned to the vicinity of the straight traveling state” means when the 3 o'clock position 45 of the steering wheel 21 is turned to the vicinity of the plus 90 ° position or to the vicinity of the minus 90 ° position (270 ° position). is there. In order to accurately determine the rotation range, it is desirable that the rotation range is within the range from the reference position Bs (0 ° position) to plus 75 ° and minus 75 ° position (over 285 °).

When the vehicle 12 shown in (a) starts to enter the left curve 62 of the travel lane 61, the right tactile sense presenting means 46 is activated to form a wave to be transmitted to the hand from left to right (Y-axis direction).
Specifically, when the vehicle 12 starts to enter the left curve 62 formed in the travel lane 61 and gradually decreases in radius, and the driver turns the steering wheel 21 to the left (counterclockwise), the steering angle of the turned steering wheel 21 In addition, the lateral acceleration is detected. Based on these pieces of information, the five linear motion means 51 of Y1 are simultaneously actuated (advanced) to push up the skin cover 53 to form a convex portion 65, so that a lateral acceleration is exerted on the driver by the sense of touch of the right hand H. It is transmitted. Immediately after forming the convex portion 65, the five linear motion means 51 of Y1 simultaneously return (retreat).

  Subsequently, as shown in (b), the Y1 linear motion means 51 returns, and at the same time, the Y2 linear motion means 51 operates to push the skin cover 53 to form the convex portion 66. Apply pressure to the tactile sensation of the palm at a distance. As a result, the lateral acceleration is transmitted to the driver by pressing the tactile sensation of the right hand H. Immediately after forming the convex portion 66, the Y2 linear motion means 51 returns.

9A to 9C are diagrams for explaining the continuation of FIG. The first tactile sense presenting means 32 of the vehicle state transmission device 11 is shown in the upper stage, and the right tactile sense presenting means 46 is developed and schematically shown in the lower stage.
Subsequently, as shown in (a), the Y2 linear motion means 51 returns and at the same time the Y3 linear motion means 51 is activated to form the convex portion 67. Apply pressure to the palm of your hand.

Furthermore, as shown in (b), since the Y3 linear motion means 51 is returned and the Y4 linear motion means 51 is activated to form the convex portion 68, the position of the position slightly separated from the previous pressing position is formed. Apply pressure to the palm of your hand.
Similarly, as shown in (c), since the Y4 linear motion means 51 is returned and the Y5 linear motion means 51 is activated to form the convex portion 71, a position slightly away from the previous pressing position. Apply pressure to the palm of your hand. Immediately thereafter, returning to FIG. 8A, the operation is repeated.

In this way, by repeating FIG. 8 (a) → (b) → FIG. 9 (a) → (b) → (c) → FIG. 8 (a), a wave (vibration) of frequency Fg is generated.
In other words, by transmitting a wave from the top (left side) to the bottom (right side) (in the direction of arrow a3) to the sense of touch of the right hand H, it is recognized that it is a lateral acceleration, and by increasing or decreasing the frequency at that time, Can tell the increase or decrease of lateral acceleration.

Next, a case where the steering wheel 21 is further rotated will be described.
FIGS. 10A to 10C are diagrams for explaining the mechanism of the tactile sensation providing means when the steering wheel is turned to the vicinity of the 90 ° position. The first tactile sense presenting means 32 of the vehicle state transmission device 11 is shown in the upper stage, and the right tactile sense presenting means 46 is developed and schematically shown in the lower stage.
“When turned to the vicinity of the 90 ° position” means that the 3 o'clock position 45 of the steering wheel 21 is within the range of the 75 ° position to the 105 ° position from the reference position Bs.

  When the steering wheel 21 is turned to the 90 ° position, the right tactile sense presenting means 46 is orthogonal to the direction (Y axis) presented when the direction of the wave transmitted to the hand is near the straight travel time (near the 0 ° position). By changing the direction (X-axis direction), the wave is formed from left to right.

  Specifically, as shown in (a), when the driver turns the steering wheel 21 to the left (counterclockwise) and the 3 o'clock position (grip part) 45 reaches the 90 ° position, the state is reached. The steering angle and lateral acceleration of the steering wheel 21 are detected, and based on these pieces of information, the five linear motion means 51 of X1 are simultaneously operated (advanced) to push the skin cover 53 and build up to form a convex portion 72. Therefore, the lateral acceleration is transmitted to the driver by the sense of touch of the right hand H. Immediately after forming the convex portion 72, the five linear motion means 51 of X1 simultaneously return (retreat).

  Subsequently, as shown in (b), the X1 linear motion means 51 returns, and at the same time, the X2 linear motion means 51 operates to push the skin cover 53 to form the convex portion 73. Apply pressure to the tactile sensation of the palm at a distance. As a result, the lateral acceleration is transmitted to the driver by pressing the tactile sensation of the right hand H. Immediately after forming the convex portion 73, the X2 linear motion means 51 returns.

  Subsequently, as shown in (c), the X2 linear motion means 51 returns, and at the same time, the X3 linear motion means 51 operates to push the skin cover 53 to form the convex portion 74. Apply pressure to the tactile sensation of the palm at a distance. As a result, the lateral acceleration is transmitted to the driver by pressing the tactile sensation of the right hand H. Immediately after forming the convex portion 74, the X3 linear motion means 51 returns.

FIGS. 11A and 11B are diagrams for explaining the continuation of FIG.
Similarly, as shown in (a), the X4 linear motion means 51 is activated to form a convex portion 75, and subsequently, as shown in (b), the X5 linear motion means 51 is activated. Since the convex portion 76 is formed, a pressure is applied to the palm tactile sensation slightly away from the previous pressing position.

In this way, by repeating FIG. 10 (a) → (b) → (c) → FIG. 11 (a) → (b) → FIG. 10 (a), a wave (vibration) of the frequency Fg is generated.
By transmitting a wave from the front (left side) to the rear (right side) (in the direction of arrow a4) to the sense of touch of the right hand H, it is recognized that the acceleration is lateral acceleration, and the lateral acceleration is increased or decreased at that time. Can tell the increase or decrease.
That is, even if the steering wheel 21 is rotated to the 90 ° position, the wave transmitted to the right hand H can be formed to flow from the left to the right in a certain direction.
Therefore, even when the steering wheel 21 is turned, uniform tactile information can always be obtained and can be transmitted more easily.

FIGS. 12A to 12C are views for explaining the mechanism of the tactile sense presenting means when the steering wheel is turned to the vicinity of the 180 ° position. The first tactile sense presenting means 32 of the vehicle state transmission device 11 is shown in the upper stage, and the right tactile sense presenting means 46 is developed and schematically shown in the lower stage.
“When turned to the vicinity of the 180 ° position” is when the 3 o'clock position 45 of the steering wheel 21 is within the range of 105 ° position (over 105 °) to 255 ° position from the reference position Bs.

  When the steering wheel 21 is rotated to the 180 ° position, the right tactile sense presenting means 46 changes the direction of the wave transmitted to the hand in the reverse direction (going from Y5 to Y1), thereby forming the wave from left to right.

  Specifically, as shown in (a), when the driver turns the steering wheel 21 to the left (counterclockwise) and reaches the 3 o'clock position 45 at the 180 ° position, the steering wheel 21 in that state Steering angle and lateral acceleration are detected, and on the basis of these information, the five linear motion means 51 of Y5 are simultaneously operated (advanced) to push the skin cover 53 and build up to form a convex part 78. Lateral acceleration is transmitted to the driver by H's sense of touch. Immediately after forming the convex part 78, the five linear motion means 51 of Y5 return simultaneously (retreat).

  Subsequently, as shown in (b), at the same time as the Y5 linear motion means 51 returns, the Y4 linear motion means 51 operates to push the skin cover 53 and form the convex portion 81. Apply pressure to the tactile sensation of the palm at a distance. As a result, the lateral acceleration is transmitted to the driver by pressing the tactile sensation of the right hand H. Immediately after forming the convex portion 81, the Y4 linear motion means 51 returns.

  Subsequently, as shown in (c), the Y4 linear motion means 51 returns, and at the same time, the Y3 linear motion means 51 operates to push the skin cover 53 to form the convex portion 82. Apply pressure to the tactile sensation of the palm at a distance. As a result, the lateral acceleration is transmitted to the driver by pressing the tactile sensation of the right hand H. Immediately after forming the convex part 82, the Y3 linear motion means 51 returns.

13A and 13B are diagrams for explaining the continuation of FIG.
Similarly, as shown in (a), the Y2 linear motion means 51 is actuated to form the convex portion 83, and subsequently, as shown in (b), the Y1 linear motion means 51 is actuated. Since the convex portion 84 is formed, a pressure is applied to the palm tactile sensation slightly away from the previous pressing position.

In this way, by repeating FIG. 12 (a) → (b) → (c) → FIG. 13 (a) → (b) → FIG. 12 (a), a wave (vibration) of the frequency Fg is generated.
By transmitting a wave from the bottom (left side) to the top (right side) (in the direction of arrow a5) to the sense of touch of the right hand H, it is recognized that the acceleration is lateral acceleration, and the lateral acceleration is increased or decreased by increasing or decreasing the frequency. Can tell the increase or decrease.
That is, even if the steering wheel 21 is rotated to the 180 ° position, the wave transmitted to the right hand H can be formed to flow from the left to the right in a certain direction.
Therefore, even when the steering wheel 21 is turned, uniform tactile information can always be obtained and can be transmitted more easily.

The tactile sense presenting means when the steering wheel rotates to the vicinity of the 270 ° position operates in the reverse direction to the operation when the steering wheel rotates to the vicinity of the 90 ° position. That is, the linear motion means 51 operates in the order of X5 to X1.
That is, even if the steering wheel 21 is rotated to the 270 ° position, the wave transmitted to the right hand H can be formed to flow from the left to the right in a certain direction.
Therefore, even when the steering wheel 21 is turned, uniform tactile information can always be obtained and can be transmitted more easily.

  “When turned to the vicinity of the 270 ° position” is when the 3 o'clock position 45 of the steering wheel 21 is within the range of 255 ° position (over 255 °) to 285 ° position from the reference position Bs. .

Although described as a wave, the wave may be recognized as a vibration.
Although the description has been given assuming that the amplitude is constant with respect to the lateral acceleration, the amplitude may be variable. By making the magnitude of the amplitude proportional to the lateral acceleration, an increase or decrease in the lateral acceleration can be transmitted.

  Since the vehicle state transmission device 11 includes the driver recognition device 26, when the conditions of the presentation pattern such as the strength of the presentation pattern and the type of information (turning or reverse) are set to personal preference, the driver recognition device 26. Can easily return to their presentation pattern.

Next, the 2nd tactile sense presentation means arrange | positioned at another operation means (accelerator pedal) 22 is demonstrated.
FIGS. 14A and 14B are explanatory views of the second tactile sense presenting means, where FIG. 14A is a cross-sectional view and FIG. 14B is a perspective view. The same components as those in the embodiment shown in FIGS. 2 and 5 are given the same reference numerals and the description thereof is omitted.

The operation means (accelerator pedal) 22 includes second tactile sense presentation means 101.
The second tactile sense presenting means 101 includes a pedal tactile sense presenting means 102 disposed on the accelerator pedal 22 and a floor tactile sense presenting means 104 disposed on the floor panel 103 of the vehicle 12.
The pedal tactile sensation presentation means 102 has a case portion 106 attached to the arm member 105 of the accelerator pedal 22, and first to third row portions 111, 112, 113 are formed in order from the front in the case portion 106. 4 each of the linear motion means 51 are arranged, and the opening 114 through the surface pressure conversion cap 52 of the linear motion means 51 is opened in the pedal plate 115 attached to the case portion 106, and the opening 114 is covered with the cover 116. ing.

  The floor tactile sense presenting means 104 has a linear motion means 51 arranged on the floor panel 103 in the vicinity of the accelerator pedal 22. Specifically, the linear motion means 51 is arranged in parallel to the third row portion 113 of the pedal tactile sense presentation means 102 and behind the position G where the extension line Lp of the pedal plate 115 and the floor panel 103 intersect (in the direction of the arrow). It is arranged.

  FIGS. 15A to 15D are views for explaining the mechanism of the second tactile sense presenting means when the vehicle is accelerated. A cross-sectional view of the second tactile sense presenting means 101 is shown on the left side of the figure, and a plan view of the second tactile sense presenting means 101 is shown on the right side of the figure. This will be described with reference to FIG.

  When accelerating the vehicle 12, the amplitude is constant, and a wave (frequency Fv) from the front (up) to the back (down) is transmitted to the heel from the tactile sensation on the back of the foot F, so that the acceleration is recognized. By increasing or decreasing the frequency Fv at that time, the increase or decrease of the vehicle speed (including acceleration) can be transmitted.

  Specifically, when the shift lever is accelerated by depressing the accelerator pedal 22 in the forward position (for example, 1 or D range), first, the first row of (a) is based on the longitudinal direction detection means 28 and the vehicle speed information. The linearly moving means 51 of the portion 111 is actuated (moved forward) to form the convex portion 117. Subsequently, the linear motion means 51 of the second row portion 112 of (b) operates (advances) to form the convex portion 118, and at the same time the linear motion means 51 of the second row portion 112 moves backward, The linear movement means 51 of the third row portion 113 is actuated (moved forward) to form the convex portion 119. Subsequently, the linear motion means 51 of the floor tactile sense presenting means 104 shown in (d) operates to form the convex portion 121, and the process returns to (a) and repeats. When the acceleration increases, the frequency becomes fast (many), and when the acceleration decreases, the frequency becomes low.

In this way, the second tactile sense presenting means 101 can present a sensation that vibration waves are transmitted from the toes to the heel when accelerating.
Further, in the case of forward movement, since waves (tactile information) are transmitted from the toes to the heel, it is possible to correspond to the state of the vehicle 12 and to convey more easily.

  FIGS. 16A to 16D are views for explaining the mechanism of the second tactile sense presenting means when the vehicle is decelerated. A cross-sectional view of the second tactile sense presenting means 101 is shown on the left side of the figure, and a plan view of the second tactile sense presenting means 101 is shown on the right side of the figure.

  When the vehicle 12 is decelerated, the amplitude is constant, and a wave (frequency Fv) from the back (down) to the front (up) is transmitted from the heel of the foot F to the toe, so that it is recognized that the vehicle is decelerating. By increasing or decreasing the frequency Fv, it is possible to convey the increase or decrease of the vehicle speed (including deceleration).

Specifically, when the accelerator pedal 22 is returned and decelerated, based on the vehicle speed information, the linear motion means 51 of the floor tactile sense presentation means 104 in (a) is first operated, and then the third row part in (b). 113, the linear motion means 51 of the second row portion 112 of (c) is actuated, and the linear motion means 51 of the first row portion 111 of (d) is actuated. The tactile sense presenting means 101 can present a feeling as if a vibration wave is transmitted from the heel to the toe when decelerating.
In addition, since the direction of the wave to be presented during forward movement is different from the direction of the wave to be presented during backward movement, the tactile information can be transmitted in an easy-to-understand manner.
When the deceleration increases, the frequency becomes faster (more), and when it decreases, the frequency becomes lower.

  The second tactile sense presenting means 101 forms a wave from the heel to the toe when decelerating, but may be set so that a wave is formed from the heel to the toe when the vehicle 12 is moved backward. . Selection of reverse or deceleration is performed by the presentation form selection switch 36.

  Although the second tactile sense presenting means 101 arranged on the operating means (accelerator pedal) 22 has been described that the operating state changes corresponding to the forward or backward movement of the vehicle 12, the operating means (steering wheel) 21 It is also possible to operate the first tactile sense presenting means 32 (consisting of the left tactile sense presenting means 44 and the right tactile sense presenting means 46) arranged in the same manner as the second tactile sense presenting means 101, and the steering wheel 21. It is also possible to change the direction (X axis, Y axis) and direction even when the angle is turned by 90 ° or more. A similar effect can be imparted to the hand.

  Whether the first tactile sensation presentation unit 32 (left tactile sensation presentation unit 44 and right tactile sensation presentation unit 46) presents information when turning (turns) or information when moving forward or backward is selected. This is done with the switch 36.

Next, the third tactile sense presenting means will be described.
FIG. 17 is a perspective view of the third tactile sense presenting means.
The third tactile sense presenting means 131 has three linear motion means 51 arranged on the seat cushion 132 of the driver's seat 15. The linear motion means 51 is disposed at the front end portion 134 of the seat cushion 132 that supports the thigh 133 (see FIG. 18), and the linear motion means 51 is disposed at the center portion 136 of the seat cushion 132 that supports the hip 135. The linear motion means 51 is disposed at the rear end 137 of the seat cushion 132 to be supported.

FIGS. 18A and 18B are diagrams illustrating the relationship between the third tactile sense presenting means and acceleration.
When the third tactile sense presenting means 131 accelerates, the third tactile sense presenting means 131 operates following the operation of the second tactile sense presenting means 101 and transmits a wave to the hip 135, so that the vehicle speed (including acceleration) is determined by the movement of the wave. By recognizing that, the frequency Fv at that time can be increased or decreased to convey the increase or decrease in vehicle speed (including acceleration).

  Specifically, when acceleration is detected, the pedal tactile sensation presentation unit 102 in (a) forms a wave from the toe as described above, and then the floor tactile sensation presentation unit 104 in (b) projects the convex portion 121. Is formed and transmitted to the bag, and then the third tactile sense presenting means 131 is continued.

FIGS. 19A to 19C are diagrams for explaining the continuation of FIG.
As shown in (a), immediately after the linear motion means 51 of the floor tactile sense presenting means 104 returns (retracts), the linear motion means 51 of the front end portion 134 disposed on the seat cushion 132 operates (advances). Since the surface material 138 stretched on the front end part 134 is raised and the thigh convex pressure part 141 is formed, the back 143 of the thigh 133 is pushed, and information (feeling of waves continuing from the heel) is transmitted to the back 143 of the thigh 133 be able to.

  Subsequently, as shown in (b), immediately after the linear motion means 51 of the front end portion 134 returns (retracts), the linear motion means 51 of the central portion 136 operates (advances) and stretches to the central portion 136. Since the front surface material 138 is energized and the front buttocks convex pressure portion 145 is formed, the buttocks 135 are pushed, and information (feeling of waves continuing from the thighs 133) can be transmitted to the buttocks 135.

Subsequently, as shown in (c), immediately after the linear motion means 51 of the central portion 136 returns (retracts), the linear motion means 51 of the rear end portion 137 operates (advances) and moves to the rear end portion 137. The stretched surface layer material 138 is energized to form the rear butt convex pressure portion 147, so that the butt 135 is pushed and information (feeling of the wave that continues from the front) can be transmitted to the butt 135. Immediately after the linear motion means 51 at the rear end 137 returns (retracts), the process returns to FIG. 18A and the operation of the linear motion means 51 is repeated.
When the acceleration increases, the frequency becomes fast (many), and when the acceleration decreases, the frequency becomes low.

As described above, when the third tactile sense presenting means 131 is accelerated, the third tactile sense presenting means 131 is activated following the operation of the second tactile sense presenting means 101, and the wave is transmitted from the thigh 133 to the buttocks 135. At this time, it is possible to present a sense that the vibration wave is transmitted to the toe → the heel → the back 143 of the thigh 133 → the buttocks 135, and the propagation range to the tactile sense can be expanded.
In addition, since it is transmitted from the back 143 of the thigh 133 to the buttocks 135, the waves flowing to the tactile senses of the thigh 133 and the buttocks 135 can be directly transmitted, and tactile information can be transmitted more easily.

The third tactile sense presenting means 131 operates when accelerated, but it is also possible to transmit a wave from the buttocks to the toes when decelerating.
In addition, the third tactile sense presenting means 131 can be operated when the vehicle 12 is bent or when a slip occurs between the tire and the road surface.

  FIGS. 20A and 20B are views for explaining the fourth tactile sense presenting means, where FIG. 20A is a plan view, and FIG. The same components as those in the embodiment shown in FIGS. 2 and 5 are given the same reference numerals and the description thereof is omitted.

  The fourth tactile sense presenting means 161 has a pin 162 that moves forward (Z-axis direction) and retreats (Z-axis direction) by the linear motion means 51, and the pin 162 is disposed higher than the upper surface 163 of the steering wheel 21 by a height H1. In addition, a convex protrusion (hooking portion) 165 is formed at a corner 164 located above the upper surface 163 of the steering wheel 21.

FIGS. 21A and 21B are comparative diagrams comparing the presence / absence of a catching portion of the fourth tactile sense presenting means.
(A) is a comparative example, and the comparative example tactile sense presenting means 171 does not have the catching portion 165. Since the tip of the pin 162 tends to be pulled toward the outside of the steering wheel 21 (in the direction of the arrow b1) by the hand 172, the bending force (stress) generated on the pin 162 tends to increase.
(B) is the fourth tactile sense presenting means 161 of the present invention, and the hand 172 contacts the catching portion 165 as indicated by the arrow b3, so that the hand 172 is regulated and held by the catching portion 165. Therefore, the bending force (stress) generated in the pin 162 can be reduced.

FIG. 22 is another configuration diagram of the fourth tactile sense presenting means, and is a cross-sectional view corresponding to FIG. Components similar to those in the embodiment shown in FIG. 20 and FIG.
Another form 161B of the fourth tactile sense presenting means is characterized in that the pin 162 is disposed lower than the upper surface 163 of the steering wheel 21 by a height H2, and the catching portion 165 is formed on the upper surface 163 of the steering wheel 21. To do.
Another form 161B exhibits the same effect as the fourth tactile sense presenting means 161.

Next, a vehicle state transmission device 11B according to another embodiment will be described.
FIGS. 23A and 23B are diagrams illustrating a vehicle state transmission device according to another embodiment, and are diagrams corresponding to FIG. 1. (A) is a figure explaining an outline, (b) is a b arrow view of (a). The same components as those in the embodiment shown in FIGS. 1 to 22 are designated by the same reference numerals and description thereof is omitted.

The vehicle state transmission device 11B according to another embodiment includes a transmission unit 34B.
The transmission unit 34B is included in the vehicle state detection device 25, and includes a vehicle stop detection unit 301 that detects the stop of the vehicle 12, an adjustment start unit 302 that inputs an adjustment start of the operation amount of the tactile sense presentation unit 32, and an operation amount. The vehicle 12 stops on the basis of the adjustment amount input means 303 that inputs and decreases the increase / decrease of the vehicle, the stop information of the vehicle stop detection means 301, the start information of the adjustment start means 302, and the increase / decrease information of the adjustment amount input means 303. And a simulation operating means 304 for outputting simulated information for operating the tactile sense presenting means 32 to the execution means 38 in the same manner as when traveling.

The “operation amount” is the number of frequencies and the amplitude.
The vehicle stop detection means 301 may be any device that detects that the vehicle 12 is stopped. For example, a vehicle speed detection device (not shown) that detects the vehicle speed included in the vehicle state detection device 25 described above. It may also serve as a mechanism for detecting the operation of a side brake (not shown). By serving also, weight reduction and cost reduction can be achieved.

  The adjustment start means 302 specifies any one of the operation means, that is, the steering wheel 21, the accelerator pedal 22, and the driver's seat 15 when adjustment is necessary. "ON / OFF" An operation unit 307 that also serves as a switch and performs a turning operation is provided, for example, disposed on the center console 308.

The adjustment amount input means 303 is used to input an increase / decrease. For example, the adjustment amount input unit 303 includes a plus part 311 and a minus part 312, and an increase is input by pressing the plus part 311, and a decrease is input by the minus part 312. The map conditions in FIG. 7 are changed. In other words, the gradient of the map is increased based on the plus information of the plus portion 311, and the gradient of the map is reduced based on the minus information of the minus portion 312.
It is also possible to translate the gradient at a constant rate.

  When the vehicle 12 is stopped, the simulation operating unit 304 outputs a map based on the increase / decrease of the adjustment amount input unit 303 and preset vehicle travel conditions (change in lateral acceleration, change in vehicle speed).

  FIG. 24 is a schematic flowchart used for a vehicle state transmission device according to another embodiment. Since ST01 to ST07 have already been described, description thereof will be omitted, and ST08 and subsequent will be described.

ST08: It is determined whether or not the vehicle is stopped. If not stopped, the process returns to ST01. When it is stopped, the process proceeds to ST09.
ST09: Read the signal from the adjustment start means 302.
ST10: It is determined whether the signal of the adjustment start means 302 is “ON” or “OFF”. When it is “OFF”, the process returns to ST01. If “ON”, the process proceeds to ST11.
ST11: An operation means is selected by the adjustment start means 302.
ST12: The operation amount of the selected tactile sensation presentation unit 32 is adjusted by plus / minus of the adjustment amount input unit 303. When changing the pattern, for example, when changing the wave traveling left and right shown in FIGS. 8 to 13, the presentation form selection switch 36 is used.

ST13: The map condition is changed based on the plus information or the minus information.
ST14: The tactile sense providing means 32 is operated based on the map whose condition has been changed, thereby adjusting while experiencing.
ST15: The signal from the adjustment start means 302 is read.
ST16: It is determined whether or not the adjustment start means 302 is “OFF”. If “ON”, the process returns to ST01. If it is “OFF”, the process proceeds to ST17. “OFF” indicates that the adjustment is complete.
ST17: Writing to the map.
Next, ST08 to ST17 will be specifically described.

Here, a case where “frequency / lateral acceleration” is already set and used in the first tactile sense presenting means 32 of the steering wheel 21 will be described.
Whether or not the vehicle 12 is stopped is determined based on, for example, whether or not the vehicle speed is 0 km / H. When the vehicle 12 is stopped, the operation unit 307 of the adjustment start unit 302 is moved from the “OFF” position to the “steering wheel” position. By turning the knob, the operation for specifying the operation unit to be adjusted is performed simultaneously with the start (ON) of the adjustment.
Next, when the plus part 311 of the adjustment amount input means 303 is pressed, the frequency increases based on the plus information. For example, with respect to the gradient of the map in FIG. 7, the gradient (angle) of the map is increased based on the plus information, and thus the frequency is increased.

  Subsequently, the map is repeatedly output in correspondence with the adjusted map and the minimum to maximum of the lateral acceleration set in the simulation operating means 304. Since the execution means 38 operates the first tactile sense presenting means 32 arranged on the steering wheel 21 based on the information of the simulation actuating means 304, the driver can operate from the minimum to the maximum when the vehicle 12 is stopped. The degree of stimulation can be adjusted within the range.

  When changing the presentation pattern of the first tactile sense presenting means 32, the presentation form selection switch 36 is used in the same manner as in ST06. For example, the current “frequency / lateral acceleration” can be changed to “frequency / vehicle speed”.

  When the adjustment is completed, when the operation unit 307 of the adjustment start unit 302 is returned to the “OFF” position, the determination is input. Based on the determination information, the conditions of the adjusted map are set and the adjustment is performed. Processing is complete.

  The adjustment process for increasing the frequency of the first tactile sensation presentation unit 32 of the steering wheel 21 has been described. However, when the frequency is decreased or the accelerator pedal 22 is specified, the stimulation is adjusted based on the same idea.

  The adjustment start unit 302 and the adjustment amount input unit 303 arranged on the center console 308 are used for adjustment, but the adjustment start unit 302 and the adjustment amount input unit 303 are not attached, and information necessary for the adjustment is obtained using the navigation device 114. You may enter.

Next, the fifth tactile sense presenting means 321 will be described.
FIGS. 25A and 25B are views for explaining the fifth tactile sense presenting means, where FIG. 25A is a side view and FIG. 25B is a perspective view. The same components as those in the embodiment shown in FIG.

The operation means (accelerator pedal) 322 has fifth tactile sense presentation means 321.
The fifth tactile sense presenting means 321 includes a vibration generating mechanism 324 attached to the accelerator pedal 322.
The accelerator pedal 322 is an existing one. A pedal plate 325 is attached to the arm member 105, and a vibration generating mechanism 324 is disposed on the upper portion 328 of the back portion 327 facing the front portion 326 on which the foot F is placed.

  The vibration generating mechanism 324 may be any mechanism that generates vibration, and is, for example, one in which an unbalance weight 332 is attached to the output shaft of the electric motor 331. Reference numeral 333 denotes a case that covers the electric motor 331.

  The fifth tactile sense presenting means 321 exhibits the same effect as the second tactile sense presenting means 101. That is, when accelerating, the pedal plate 325 vibrates by the vibration generating mechanism 324, so that the vibration is transmitted to the foot F and information can be transmitted.

Further, in the fifth tactile sense presenting means 321, the pedal plate 325 vibrates by the vibration generating mechanism 324, so that it is not necessary to directly press the foot F to vibrate.
Further, since the vibration generating mechanism 324 is disposed on the back portion 327 of the pedal plate 325, the fifth tactile sense presenting means 321 (vibration generating mechanism 324) does not directly touch the shoe sole of the occupant and is wet on a rainy day. And can prevent the negative effects of sand and dust.

  The vehicle state transmission device of the present invention is suitable for a device that is operated when driving a vehicle.
