Description

  The present invention belongs to the technical field of a driving posture adjusting device that adjusts a driving position of a driver.

The conventional driving posture adjusting device includes posture adjusting means for adjusting the position of the steering wheel, the pedal position, and the seat height in order to optimize the field of view and posture of drivers having different physiques. For example, the driver can adjust the three positions by operating an adjustment start operation unit and an adjustment end operation unit provided on the steering wheel to obtain a desired driving posture (for example, Patent Document 1). reference.).
Patent Document 1 Japanese Patent Application Laid-Open No. 7-96784

  However, in the above prior art, the driver must manually adjust the driving posture, which is troublesome. Furthermore, since the driving posture collapses during operation, it is difficult to adjust to a preferred position at one time.

  In order to reduce the burden of adjustment, even if a system that detects the driver's physique on the device side and automatically adjusts the position is used, typical physique values such as height can be detected, It is difficult to detect the length between the joints of the upper and lower limbs (hereinafter referred to as link length) that directly affects the steering position and the accelerator pedal position. Furthermore, there is a problem that the link lengths of the upper limbs and lower limbs vary widely among individuals, and the correlation between the height and the link length is low.

  The present invention has been made paying attention to the above-mentioned problems, and the object of the present invention is to adjust the posture to be able to easily adjust to the user's favorite driving posture at a time and easily obtain the optimum driving posture according to the physique. To provide an apparatus.

In order to achieve the above object, in the present invention, a driving posture adjusting device capable of arbitrarily adjusting three positions of a steering wheel position, a pedal position including at least an accelerator pedal and a brake pedal, and a driver's seat height. In
When the driver manually adjusts the position of either the steering wheel or the pedal while pushing and pulling with the upper limb or the lower limb, the posture adjusting means for adjusting the other two positions based on the adjusted position is provided. Provided.

  In the present invention, the driver can manually adjust the position of the steering wheel or the pedal by pushing and pulling, and the other two positions are adjusted based on the adjusted position. It can be adjusted to your preferred driving posture at a time, and you can easily obtain the optimal driving posture that matches your physique.

  Hereinafter, the best mode for carrying out the present invention will be described based on Example 1 and Example 2.

First, the configuration will be described.
FIG. 1 is a side view showing the configuration of the driving posture adjusting apparatus.
The pedal 11 includes an accelerator pedal 11 a and a brake pedal 11 b, which are fixed to the movable floor 13. The brake pedal 11b is connected to the booster 15 and the master cylinder 16 by brake transmission means 14 which is a flexible cable. The accelerator pedal 11a is an electronic throttle and is not mechanically connected to the engine.

  The movable floor 13 is engaged on a movable floor slide rail 18 installed under the seat cushion 17a of the seat 17, and can move in the sliding direction (the front-back direction with a gradient) of the movable floor slide rail 18.

  Therefore, the position of the pedal 11 fixed to the movable floor 13 (hereinafter, the point where the pedal 11 is stepped on with the sole of the driver is used as the position of the pedal 11) is the front and rear having the same gradient as the movable floor slide rail 18. Will move in the direction. The means for moving this is a pedal position driving means 35 which is a motor.

FIG. 2 is a plan view showing the configuration of the driving posture adjusting apparatus.
As shown in FIG. 2, the steering 20 and the steered rod 21 are connected by a steering transmission means 22 that is a flexible cable, and the position of the steering 20 can be freely moved.

  Further, as shown in FIG. 2, the steering wheel 20 is cantilevered by a middle steering post 20a, and the steering post 20a rotates in the front-rear direction around a steering post fulcrum 23 below the seat 17. Thus, the position of the steering wheel 20 is adjusted.

  The position adjustment trajectory is the position movement direction of the steering wheel 20 in FIG. The position adjustment is performed by a steering position driving means 24 which is a motor coaxially installed on the steering post fulcrum 23. In addition, steering position detection means 31 for detecting the position of the steering 20 is provided.

FIG. 3 shows the steering longitudinal load detecting means 32 for detecting the force by which the driver pushes and pulls the steering wheel 20 in the longitudinal direction of the vehicle.
The steering longitudinal load detecting means 32 is provided on the steering post 20a, and specifically is a strain gauge that measures the distortion of the steering post 20a in the vehicle longitudinal direction.

  In the first embodiment, as a mechanism for adjusting the height of the seat cushion 17a, as shown in FIG. 1, an X link 25 is provided below the seat cushion 17a, and by changing the angle of the X link 25, The position of the sheet 17 can move substantially in the vertical direction.

  A seat position driving means 33, which is a coaxial motor, is provided at the fulcrum below the rear portion of the X link 25. By driving this, the X link rear fulcrum 25a slides on the X link rear fulcrum slide rail 26. Then, the angle of the X link 25 changes and the seat cushion 17a moves obliquely upward.

  Assuming that the driver's hip point is the position of the seat 17, the position of the seat 17 moves in the position movement direction of the seat 17 in FIG. Since the movable floor slide rail 18 is coupled to the seat cushion 17a, when the position of the seat 17 moves up and down, the movable floor 13, that is, the position of the pedal 11 also moves up and down at the same time. Further, the seat back angle of the seat 17 can be manually adjusted, but has a seat back angle detecting means 34 for detecting the seat back angle θ.

  In the first embodiment, the movable floor driving means 19, the steering position driving means 24, the seat position driving means 33, the movable floor slide rail 18, the X link 25 and the like are all disposed under the seat 17 and are configured integrally with the seat 17. doing.

  This is aimed at ease of assembly work when the present apparatus is mounted on a vehicle and effective use of the space under the seat 17. In addition, by attaching the movable floor slide rail 18 under the seat 17, when the movable floor 13 is lowered to the lowest position, the movable floor slide rail 18 can be lowered to substantially the same position as the vehicle floor 27.

  The position adjustment of the position of the pedal 11, the position of the steering wheel 20, and the position of the seat 17 is performed by the posture adjusting means 28 for controlling the pedal position driving means 35, the steering position driving means 24, and the seat position driving means 33, respectively.

  In addition, when the driver sits on the seat cushion 17a and the driver sits down, the load on the buttocks of the driver is detected, and the height, which is a representative value of the physique, is estimated and output to the posture adjusting unit 28.

  The posture adjustment means 28 is the height of the driver obtained by the physique detection means 29, the state of the vehicle obtained by the key position detection means 30, and the force in which the driver pushes and pulls the steering 20 in the longitudinal direction of the steering wheel 20. Based on the load, target values of the position of the pedal 11, the position of the steering wheel 20, and the position (height) of the seat 17 are calculated, and a drive command is output to each drive unit.

Here, the concept of the driving posture adjusting method by the posture adjusting means 28 will be described.
In the first embodiment, an automatic adjustment mode in which the height of the driver is detected and the positions of the pedal 11, the steering wheel 20, and the seat 17 are automatically adjusted, and a manual adjustment mode in which the driver manually adjusts is combined. is there.

As described above, when the respective positions are automatically adjusted only by the height, there is a possibility that the optimal position of the driver cannot be adjusted because the variation of the upper limb and the lower limb with respect to the height is large. In particular, the position of the pedal 11 is sensitive to the appropriate position, and must be accurately adjusted to the appropriate position of the driver.
Therefore, in the first embodiment, the final fine adjustment is performed manually, and the position is automatically adjusted to a position where manual adjustment is easy in the previous automatic adjustment.

  Here, the concept of manual adjustment will be described. As described above, when adjusting the driving posture, the position of the pedal 11 is important, but the physical factor of the driver that controls the position of the pedal 11 is the link length of the lower limb. The link length of the lower limbs varies greatly with respect to the height, but is considered to have a high correlation with the link length of the upper limbs.

  For example, people with long legs have long hands. The link length of the upper limb is a main factor that determines the position of the steering wheel 20. After all, it is considered that the position of the steering wheel 20 is highly correlated with the position of the pedal 11.

  Further, as a method capable of adjusting the posture without breaking the driving posture, it is considered best to adjust the position by pushing and pulling the position of the steering wheel 20 and particularly pulling the steering wheel 20 that is easy to apply force and finely adjust.

  Therefore, in this manual adjustment mode, the driver pulls (or pushes) the steering wheel 20 to determine an appropriate steering wheel 20 position, and automatically adjusts the position of the pedal 11 in conjunction with the manually adjusted steering wheel 20 position. It shall be.

FIG. 4 shows the automatic adjustment mode before the manual adjustment mode.
In the automatic adjustment mode before the manual adjustment mode, the position of the steering wheel 20 and the position of the pedal 11 are adjusted slightly forward (in a direction far from the driver) from the appropriate position estimated from the height, so that any driver can operate the steering wheel 20. Pull for manual adjustment.

  As shown in FIG. 4, when the driver gets on and off, the position of the steering wheel 20 is S0, the position of the pedal 11 is P0, and the position of the seat 17 is C0. Here, the steering 20 and the pedal 11 are retracted to the front end side in the vehicle front-rear direction so that the driver can easily get on and off, and the position of the seat 17 is lowered to the lowest point.

  When the driver gets in, the height H of the driver is detected, and the steering position, pedal position, and seat position are automatically adjusted to positions S ′, P ′, and C ′ in the drawing, respectively. The steering position S ′ and the pedal position P ′ are positions farther from the driver than the average appropriate position of the height H. The position C ′ of the sheet 17 is an average appropriate position of the height H.

  Thereafter, when the driver pulls the steering wheel 20 and adjusts it to the appropriate steering position Sb, the pedal position automatically moves to the position Pb in conjunction therewith.

  When manual adjustment is completed, the seat position automatically moves up and down to match the adjusted steering position. The seat position is adjusted so that the driver's eye point (eye height) is almost the same for any physique driver.

  When the driver manually adjusts the steering wheel 20, if the seat position moves, the driver may be confused. Therefore, the position of C ′ that is automatically adjusted in advance is the average appropriate position of the detected height H, After manual adjustment of the steering position, C ′ is automatically finely adjusted.

Next, a specific adjustment method will be described.
FIG. 5, FIG. 6, and FIG. 7 show the characteristics of each position with respect to the detected height H during automatic adjustment.

FIG. 5 shows the relationship between the height H and the steering position S.
As the height decreases, the steering position is set to the rear of the vehicle. This characteristic is linearly connected with the smallest height (here 1450 mm) as Smax and the largest height (here 1900 mm) as Smin.

  When the detected height is H, first, an average aptitude position SH is obtained from this characteristic. Next, a position obtained by subtracting Sσ from the position SH, that is, a position where the position of the steering wheel 20 is moved away from the driver by Sσ is S ′, and the steering position is adjusted to S ′ during automatic adjustment.

  Here, Sσ is a value of the standard deviation of the steering position distribution when a person of the same height matches the appropriate steering position. That is, in the case of normal distribution, the position corresponds to about 84th percentile.

FIG. 6 shows the relationship between height H and pedal position P.
The pedal position is set to the rear of the vehicle as the height decreases between Pmin and Pmax. When the detected height is H, the average aptitude position PH is obtained from this characteristic.

  Next, a position obtained by subtracting Pσ from the position PH, that is, a position where the pedal position is moved away from the driver by Pσ is P ′, and the pedal position is adjusted to P ′ at the time of automatic adjustment. Here, Pσ is a standard deviation value of the pedal position distribution when a person of the same height matches the appropriate pedal position.

FIG. 7 shows the relationship between the height H and the position C of the sheet 17.
In order to make the height of the eye point constant regardless of the height, the smaller the height, the higher the sheet position C, that is, the position where the eye point is higher. As described above, the sheet position is set to C ′ as the average suitability position CH, and is adjusted to C ′ during automatic adjustment.

FIG. 8 shows the relationship between the amount by which the driver manually adjusts the steering position and the pedal position interlocking amount during manual adjustment.
The amount by which the driver manually adjusts the steering position during manual adjustment is the amount of difference between the manually adjusted position and the automatically adjusted steering position S ′, and is hereinafter referred to as ΔS. Further, the amount of movement of the pedal 11 in conjunction with the adjustment amount of the steering position is a difference amount of the position at the time of interlocking with the automatically adjusted pedal position P ′, and is hereinafter referred to as ΔP.

  At this time, the pedal position interlocking amount ΔP at the time of manual adjustment is proportionally increased as the steering position movement amount ΔS at the time of manual adjustment increases.

FIG. 9 shows the relationship between the position movement amount ΔS of the steering wheel 20 during manual adjustment and the seat position interlocking amount ΔC during manual adjustment.
As in the case of the pedal position interlocking amount ΔP, ΔS and ΔC have a proportional relationship. However, since the seat 17C ′ after the automatic adjustment is an average appropriate position of the height H, manual adjustment is performed when ΔS is Sσ. The sheet position interlocking amount ΔC at that time is set to zero.

Further, the appropriate steering position of the driver needs to be corrected by the seat back angle θ because the shoulder position changes when the seat back angle θ changes. Therefore, the maximum value Smax of the steering position and the minimum value Smin of the steering position used in FIGS. 5, 8, and 9 are determined by the seat back angle θ.
FIG. 10 shows the relationship between the seat back angle θ and the maximum value Smax of the steering position, and FIG. 11 shows the relationship between the seat back angle θ and the minimum value Smin of the steering position. The characteristic is that Smax and Smin increase as θ increases between θmin and θmax.

Next, the operation will be described.

  In step S16, the pedal position driving means 35 is driven so that the pedal position P = P ′ + ΔP, and the process proceeds to step S17.

  In step S17, the steering longitudinal load detecting means 32 determines whether or not the steering longitudinal load is a constant value. If YES, the process proceeds to step S12. If NO, the process proceeds to step S18.

  In step S18, the seat position movement amount ΔC during manual adjustment is calculated from the steering position movement amount ΔS based on FIG. 9, and the process proceeds to step S19.

  In step S21, it is determined whether the key is OFF. If YES, this control is terminated, and if NO, the process proceeds to step S1.

[Attitude adjustment control action]
At the time of boarding, the flow proceeds from step S1 to step S20 to step S21 in the flowchart of FIG. That is, in step S20, the steering position, the pedal position, and the seat position are adjusted to S0, P0, and C0 that are positions where the driver can easily get on and off.

  When the driver turns the key to start the engine, the flow proceeds from step S1, step S2, step S3, step S4, step S5, step S6, step S7, step S8, and step S9. That is, in step S9, the steering position is adjusted to S ', the pedal position is set to P', and the seat position is set to C 'so as to obtain an optimum posture based on the height H of the driver.

  Subsequently, when the driver pushes and pulls the steering wheel 20 and manually adjusts the position, step S10 → step S12 → step S13 → step S14 → step S15 → step S16 → step S17 → step S18 → step The flow proceeds to S19. That is, in step S14, the steering position movement amount ΔS at the time of manual adjustment is calculated. In step S15, the pedal position movement amount ΔP corresponding to ΔS is calculated.

Next, the effect will be described.
In the driving posture adjusting apparatus according to the first embodiment, the following effects can be obtained.

  (1) The posture adjusting means 28 adjusts the pedal position and the seat position based on the steering position movement amount ΔS at the time of manual adjustment by the driver's push-pull operation. It can be adjusted to your preferred driving posture, and you can easily obtain the optimal driving posture that matches your physique.

  (2) The posture adjustment means 28 allows the driver to manually adjust the steering position when the steering longitudinal load is greater than or equal to a certain value between the time of getting on and the time of departure. Can make a positive decision.

  (3) The posture adjusting means 28 adjusts the steering position, pedal position and seat position according to the height H of the driver when the driver gets on, and then adjusts the steering position manually when the driver manually adjusts the steering position. Adjust the two positions. That is, the last fine adjustment is manually performed, and the automatic adjustment before the automatic adjustment is automatically performed to a position where manual adjustment can be easily performed, so that an optimal driving posture slightly different for each driver can be surely obtained.

  (4) The posture adjustment means 28 adjusts the steering position and the pedal position to a position farther from the average appropriate position SH of the driver's height when the driver gets on the vehicle. It can be performed by a pulling operation that does not break the driving posture and is easy to apply force.

  (5) When the driver gets on, the posture adjusting means 28 adjusts the steering position and the pedal position to positions far from the average appropriate positions SH and PH of the driver's height, and the seat position is the average of the driver's height. The eye point can be kept constant regardless of the height difference of the driver because the adjustment is made to the appropriate position CH.

  (6) When the driver manually adjusts the steering position, the posture adjusting means 28 changes the other two positions in accordance with the seat back angle θ, so that the driver's shoulder position due to the change in the steering position. Can be accurately grasped based on the backrest angle θ, and an optimal driving posture can be obtained.

  In the first embodiment, in the manual adjustment mode, the driver pushes and pulls the steering wheel 20 in the vehicle front-rear direction to adjust, and the pedal position is automatically adjusted in conjunction with this. This is based on the fact that human upper limb link length and lower limb link length are highly correlated. According to this idea, it is conceivable that the driver adjusts the pedal position and interlocks the steering position accordingly.

FIGS. 13 to 15 show a case where the driver adjusts the position of the pedal 11 and interlocks the position of the steering wheel 20.
The method for adjusting the pedal position of the driver uses the floor longitudinal load detection means 36 shown in FIG. This is means for detecting the load in the front-rear direction of the kite, and when the driver applies a force in the front-rear direction to the kite, the position of the brake pedal 11b moves in the direction in which the force is applied. The hook is shaped to be caught at the front and rear, making it easy to apply force in the front-rear direction.

  In conjunction with this adjusted pedal position, the steering position and seat position are automatically adjusted. FIG. 14 shows the relationship between the pedal position movement amount ΔP and the steering position interlocking amount ΔS during manual adjustment, and FIG. 15 shows the relationship between the pedal position movement amount ΔP and the seat position interlocking amount ΔC. As shown in the figure, both have characteristics proportional to the amount of movement of the pedal 11 position adjusted by the driver.

  Next, the effect will be described.

  In the driving posture adjusting apparatus of the second embodiment, the following effects can be obtained in addition to the effects described in (1) and (3) to (6) of the first embodiment.

  (7) The posture adjustment means 28 allows the driver to manually adjust the pedal position when the floor longitudinal load is greater than or equal to a certain value between the time of getting on and the departure of the vehicle. Can be reliably determined.
