Description

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

As a conventional driving posture adjusting device, the position of the pedal is movable in the front-rear direction, and the smaller the physique, the more the driver moves the seat forward and upward, and the pedal moves backward, regardless of the physique difference. A technique is known in which the eye position (eye point) is always set to an appropriate height (see, for example, Patent Document 1).
JP-A-7-96784

  However, in the above prior art, the posture is changed only by the physique, but the requirements required for the driving posture are not only the physique but also the driving style and driving environment, etc. Should be optimized.

  Here, even if the posture should be changed depending on the driving style and driving environment, it is difficult for the driver to adjust the steering position, pedal position, and seat position individually, which is troublesome. It is difficult to adjust in consideration of the balance of the overall posture.

  The present invention has been made paying attention to the above problems, and an object of the present invention is to provide a driving posture adjusting device capable of obtaining a driving posture desired by the driver.

In order to achieve the above-described object, in the present invention, at least the front-and-rear position of the seat and the angle of the seat back are varied, and the driving posture adjusting means for adjusting the driving posture and the eyepoint, and the driving posture adjustment according to a predetermined parameter In a driving posture adjustment device comprising driving posture control means for driving the means,
Provide posture condition input means for the driver to input the posture condition that is the purpose and amount that the driver wants to change the driving posture and eye point,
The driving posture control means adjusts the driving posture and the eyepoint according to the inputted posture condition.

  According to the present invention, since the driving posture and the eyepoint are adjusted according to the posture condition input by the driver, the driving posture according to the posture condition desired by the driver can be obtained.

  Hereinafter, the best mode for carrying out the driving posture adjusting apparatus of the present invention will be described based on the first embodiment.

First, the configuration will be described.
FIG. 1 is a side view illustrating the configuration of the driving posture adjusting apparatus according to the first embodiment, and FIG. 2 is a plan view illustrating the configuration of the driving posture adjusting apparatus according to the first embodiment.

  An accelerator pedal 1 and a brake pedal 2 are fixed to a movable floor 3, and the brake pedal 2 is connected to a booster 5 and a master cylinder 6 by brake transmission means 4 that is a flexible cable. The accelerator pedal 1 is an electronic throttle and is not mechanically connected to an engine not shown.

  The movable floor 3 is engaged on a movable floor slide rail 8 installed under the seat cushion 7a of the seat 7, and can move in the sliding direction (the front-back direction with a gradient) of the movable floor slide rail 8. Therefore, the positions of the pedals 1 and 2 fixed to the movable floor 3 (hereinafter, the heel point assuming the driver's heel position as a representative value of the pedal position) has the same gradient as the movable floor slide rail 8. It will move back and forth. The means for moving this is movable floor drive means 9 which is a motor.

  As shown in FIG. 2, the steering wheel 10 and the steering rod 11 are connected by a steering transmission means 12 which is a flexible cable, and the steering position can be freely moved. The steering is cantilevered by a steering post 13 in the figure, and the steering post 13 rotates in the front-rear direction around the steering post fulcrum 14 below the seat cushion 7a to adjust the position of the steering. Can do. The position adjustment is performed by a steering front / rear position driving means 15 which is a motor coaxially installed on the steering post fulcrum 14. Further, the steering position can be adjusted in the vertical direction by the steering vertical position driving means 16 that adjusts the length of the steering post 13 in the vertical direction.

  In addition, a mechanism for adjusting the height of the seat is provided. As shown in FIG. 1, an X link 17 is provided under the seat cushion 7a, and the lower rear fulcrum 17a of the X link 17 can move on the X link rear fulcrum slide rail 18, and the lower front of the X link 17 The part fulcrum 17b is supported by the movable floor 3. The lower rear fulcrum 17a of the X link 17 is provided with a seat vertical position driving means 19 that is a coaxial motor. By driving the seat vertical position driving means 19, the lower rear fulcrum 17a of the X link 17 By sliding on the link rear fulcrum slide rail 18, the angle of the X link 17 changes, and the seat cushion 7a moves in the vertical direction. The driver's hip point in the figure can be adjusted substantially vertically.

  Since the movable floor slide rail 8 is coupled to the seat cushion 7a, when the seat reference point moves up and down, the movable floor 3 also moves up and down at the same time. A seat front / rear slide rail 19 is provided below the fulcrum of the X link 17 and the seat 7, the steering wheel 10, and the movable floor 3 are moved back and forth integrally by the seat front / rear position driving means 20. Can do.

  Further, a seat back driving means 21 is provided at a connecting portion of the seat cushion 7a and the seat back 7b of the seat 7, and by driving the seat back driving means 21, the seat back angle can be freely adjusted.

  In the first embodiment, the six driving posture adjusting means (movable floor driving means 9, steering front / rear position driving means 15, steering vertical position driving means 16, seat vertical position driving means 19, seat front / rear position driving means 20 and seat described above are used. By means of the back drive means 21), it is possible to adjust the driver's eye point forward and backward, up and down, the seat back angle tilt forward and backward, the hip point forward and backward and up and down, the steering position forward and backward and up and down, and the heel point forward and backward and up and down.

  Control of each driving means for adjusting the position is performed by an attitude adjusting means (driving attitude control means) 22. This posture adjusting means 22 calculates the target posture of the driver based on the posture condition desired by the driver input to the posture condition input means 23. Subsequently, the target value of each driving means is calculated from the target driver posture, and a driving command is output to each driving means. Although the details will be described later, the posture condition input means 23 is a method of inputting posture conditions with a touch panel on the vehicle interior display.

Next, the operation will be described.
[Driving posture adjustment method]
Representative points when adjusting the posture are shown in FIG. First, the eyepoint is determined as the order of determining the posture. Next, the hip point is determined based on the eye point-hip point distance Lu and the upper body tilt angle θb that are uniquely determined by the physique. Here, the body tilt angle θb is an angle with respect to the vertical of the line connecting the eye point and the hip point. Next, the heel point is determined starting from the hip point. The steering position is determined by the positional relationship with respect to the eye point.

  The representative parameters at the time of posture adjustment will be described. The front end position of the roof trim is set as a reference point for the upper level of the forward visibility, and the rear and lower distances from this point to the eye point are set as an eye point rear position Ye and an eye point lower position Ze, respectively. The angle between the eye point and the hip point is the upper body tilt angle θb as described above. The forward and downward distances from the hip point to the heel point are a heel point forward position Yh and a heel point downward position Zh, respectively. Further, the forward and downward distances from the eye point to the steering position are a steer forward position Ys and a steer lower position Zs, respectively. Here, since the driver's lower limb length is determined, the heel point forward position Yh is uniquely determined when the heel point lower position Zh is determined. The relationship is shown in FIG.

  In FIG. 4, when the heel point lower position Zh increases, the heel point front position Yh decreases. That is, there are six independent parameters that define the posture: eye point rear position Ye, eye point lower position Ze, upper body tilt angle θb, heel point lower position Zh, steer front position Ys, and steer lower position Zs. These parameters are assumed to have reference values for a standard posture. The reference values for eye point rear position Ye, eye point lower position Ze, upper body tilt angle θb, heel point lower position Zh, steer front position Ys, and steer lower position Zs are Ye ′, Ze ′, θb ′, Zh ′, Let Ys 'and Zs'.

In the first embodiment, based on this reference value, a final parameter value is calculated by multiplying a correction coefficient (hereinafter referred to as a driving posture correction coefficient) according to a driver's instruction. Although the driving posture correction coefficient will be described in detail later, there are six types for each of the six types of parameters, and KYei, KZei, Kθbi, KZhi, KYsi, and KZsi (where i = 1 to 6). The final parameter value is calculated by the following formula.
Ye = Ye'x KYe1x KYe2x KYe3x KYe4x KYe5x KYe6
Ze = Ze 'x KZe1 x KZe2 x KZe3 x KZe4 x KZe5 x KZe6
θb = θb '× Kθb1 × Kθb2 × Kθb3 × Kθb4 × Kθb5 × Kθb6
Zh = Zh '× KZh1 × KZh2 × KZh3 × KZh4 × KZh5 × KZh6
Ys = Ys' x KYs1 x KYs2 x KYs3 x KYs4 x KYs5 x KYs6
Zs = Zs' × KZs1 × KZs2 × KZs3 × KZs4 × KZs5 × KZs6… (1)

[Driving posture adjustment according to posture conditions]
Next, the attitude condition input means 23 and a method for deriving each driving attitude correction coefficient will be described.
FIG. 5 shows a menu screen 24 of the posture condition input means 23. A driving posture adjustment instruction is given in four categories (items). There are four types: 1 driving style, 2 fields of view, 3 space in the vehicle interior, and 4 external driving environment, and selecting one of them will bring up the submenu described below.

(Driving style)
A driving style sub-menu screen 25 is shown in FIG. Here, the degree of sport is specified. When the “sports” button 25a is selected, the degree of sports increases stepwise. On the other hand, when the “slow” button 25b is pressed, the sporting degree gradually decreases. The driving posture is changed according to the degree of sports. When the sporting degree is high, the height of the hip point to the heel point is reduced to facilitate the pedal operability, in particular, the fine pedal operation, and the eye point is lowered and rearward to make it easy to see the road surface condition in the distance. In addition, the height of the steering is increased and the seat back 7b is tilted forward so that force can be easily applied to the operating limb.

  FIG. 7 shows the relationship between the sport level and the driving posture correction coefficient. The number at the end of the sign of the driving posture correction coefficient here is 1. When the sporting degree is increased, the eye point lower position coefficient KZe1 and the eye point rear position coefficient KYe1 are both increased, and the heel point lower position coefficient KZh1, the steer lower position coefficient KZs1, and the body tilt angle coefficient Kθb1 are decreased. The other driving posture correction coefficient is 1.0, and postures other than the above are not changed.

(Visibility)
A view sub-menu screen 26 is shown in FIG. Here, the degree of visibility is designated. When the “nearly visible” button 26a is selected, the degree of visibility increases stepwise. On the other hand, when the "normal" button 26b is pressed, the size is gradually reduced and the normal state is obtained. The position of the eye point is changed according to the sport level. The higher the visibility, the higher the eye point, the better the road surface near the vehicle can be seen. However, since the head approaches the front end of the roof trim, it is a posture in which the annoyance above falls compared to the reference posture.

  FIG. 9 shows the relationship between the degree of visibility and the driving posture correction coefficient. The number at the end of the sign of the driving posture correction coefficient here is 2. When the visibility is higher than a certain level, the eye point lower position coefficient KZe2, the eye point rear position coefficient KYe2, and the body tilt angle coefficient Kθb2 are decreased. The other driving posture correction coefficient is 1.0.

(Vehicle interior space)
FIG. 10 shows a submenu screen 27 relating to the vehicle interior space. This is divided into three items: "front wide", "above overhead" and "rear rear seat". FIG. 11 shows driving posture correction coefficients that are changed when each item is selected. The number at the end of the sign of the driving posture correction coefficient here is 3. Pressing the “front wide” button 27a increases the distance between the instrument panel and the front window with the eye point in the rear. The eye point rear position coefficient KYe3 is increased. When the “overhead” button 27b is pressed, the eye point is lowered to increase the head clearance. Increase eye point lower position coefficient KZe3. When the “rear seat wide” button 27c is pressed, the front and rear spaces of the driver seat are reduced in order to increase the foot space of the rear seat. Although the eye point is put forward, in order to prevent the movable floor 3 from interfering with the vehicle body floor, the height of the hip point to the heel point is increased, that is, the distance between the hip point and the heel point is reduced, and the seat back 7b. To respond. Therefore, the eye point rear position coefficient KYe3 is decreased, the heel point lower position coefficient KZh3 is increased, and the body tilt angle coefficient Kθb3 is decreased.

(External driving environment)
FIG. 12 shows a submenu screen 28 related to the external traveling environment. This is divided into five items: “Backlight”, “Night”, “Rain”, “Snow” and “Fog”.

  First, a case where the “backlight” button 28a is pressed will be described. This is anti-glare of sunlight and moves the eye point to a position where sunlight does not hit as shown in FIG. Let θsun be the sun's downward angle. This can be calculated if the vehicle's latitude, date, and time are known.

  FIG. 14 shows the relationship between the sun angle θsun and the driving posture correction coefficient. The number at the end of the sign of the driving posture correction coefficient here is 4. If θsun is equal to or greater than a certain value, the backlight does not enter even at the normal eyepoint. Therefore, the eyepoint is changed according to θsun when it is equal to or smaller than the certain value. As θsun is smaller, the eye point is moved backward and upward, so the eye point rear position coefficient KYe4 is increased and the eye point lower position coefficient KZe4 is decreased.

  Next, a case where the “night” button 28b, the “rain” button 28c, the “snow” button 28d, and the “mist” button 28e are pressed will be described. These are for adjusting the eye point and posture at two angles of visibility deterioration and necessity of eyelid manipulation.

  FIG. 15 shows the relationship between the external driving environment condition and the visibility deterioration degree. The fog is the worst visibility. The eye point is changed according to the degree of visual field deterioration. When the field of view is poor, the eye point is set forward and slightly upward so that the front can be seen well.

  FIG. 16 shows the relationship between the degree of visibility deterioration and the driving posture correction coefficient. The number at the end of the sign of the driving posture correction coefficient here is 5. Both the eye point rear position coefficient KYe5 and the eye point lower position coefficient KZe5 are made smaller.

  FIG. 17 shows the relationship between the external driving environment condition and the necessity level of the dredging operation. The necessity of dredging operation refers to the degree to which a rapid dredging recovery operation is required due to sudden changes in the external driving environment, surrounding obstacles, and the road surface condition. For example, in the case of a snowy road surface, it is necessary to be prepared to cope with the dredging due to freezing, dredging, tire slip, and the like.

  FIG. 18 shows the relationship between the necessity level of the dredging operation and the driving posture correction coefficient. The number at the end of the sign of the driving posture correction coefficient here is 6. The heel point is increased to increase the quick changeover operation and pedal controllability. The heel point lower position coefficient KZh6 is increased, and the steer front position coefficient KYs6 is decreased.

[Attitude adjustment limiter]
Each driving posture correction coefficient is obtained by the method described above, and the eye point rear position Ye, the eye point lower position Ze, the body tilt angle θb, the heel point lower position Zh, the steer front position Ys, the steer using the formula (1). The lower position Zs is calculated. However, in Formula (1), since each correction coefficient is multiplied in parallel, the calculated dimension value may exceed the range of general posture adjustment. For example, when the eye point is put forward, if it is put too far forward, the distance from the front end of the roof trim is too close and the user feels annoyed. Therefore, before changing the posture using each driving means, a limiter is applied to each dimension value with a limit value. As shown in FIG. 19, a minimum value and a maximum value are set for each dimension value.

Next, the effect will be described.
In the driving posture adjusting apparatus of the first embodiment, the effects listed below can be obtained.

  (1) A posture condition input means 23 is provided for inputting a posture condition, which is a purpose and quantity for which the driver wants to change the driving posture and eyepoint, and the posture adjusting means 22 is adapted to the driving posture and eye according to the inputted posture condition. In order to adjust the point, a driving posture and an eye point adapted to the posture condition desired by the driver can be obtained.

  (2) The accelerator pedal 1 and the throttle, the brake pedal 2 and the booster 5 and the steering wheel 10 and the steered rod 11 are connected by a flexible transmission means, and the brake pedal 2 and the accelerator pedal 1 are fixed, and the vehicle floor A movable floor 3 that can move up and down and back and forth, and a seat 7 that can move up and down and back and forth with respect to the movable floor 3, and a movable floor drive means 9 and a steering back and forth position drive means 15 as posture adjusting means, Since the steering vertical position driving means 16, the seat vertical position driving means 19, the seat front / rear position driving means 20, and the seat back driving means 21 are provided, the driving posture according to the posture condition regardless of the physique of the driver. And eye point can be optimized.

  (3) Since the posture condition input means 23 includes input items including driving style, field of view, vehicle interior space, and external driving environment, it is adapted to the driving style and driving environment by an instruction method that is intuitively understandable by the driver. Driving posture and eye point can be realized.

  (4) The posture condition input means 23 can input the degree of driving as a sporting degree Sp as a driving style, and the degree of sporting speed operation can be input. In order to reduce the height difference between the driver's hip point and the movable floor 3, lower the eye point with respect to the vehicle, lower the eye point, raise the steering wheel 10, and reduce the angle of the seat back 7b. As the sports degree Sp is higher, it is easier to operate the minute pedal, to easily see a distant road surface state, and to easily apply force to the operating limb. In addition, the higher the sporting degree Sp, the lower the center of gravity, so that the vehicle maneuverability such as turning performance is improved.

  (5) The posture condition input means 23 can input as the visibility the degree of visibility near the front of the vehicle as the visibility V, and the posture adjustment means 22 increases the eyepoint as the visibility V increases. Is advanced and raised with respect to the vehicle, and the angle of the seat back 7b is reduced, so that the visibility of a nearby road surface can be improved as the visibility V increases.

  (6) The posture condition input means 23 can individually input the degree of widening the front panel, overhead, and rear seat spaces up to the instrument panel and the front window as the vehicle interior space. The higher the degree of widening the front part, the lower the eye point with respect to the vehicle, the higher the degree of overhead, the lower the eye point, and the wider the rear seat, the higher the eye point with respect to the vehicle. In order to increase the height difference between the hip point and the movable floor 3 and reduce the angle of the seat back 7b so that the forward and backward distance of the driving posture is reduced and the angle of the seat back 7b is reduced, A driving posture and eyepoints that take into account the presence or absence of a car can be realized.

  (7) Attitude condition input means 23 includes anti-glare against backlight as an external running environment, and attitude adjustment means 22 estimates the angle of backlight from sun downward angle θsun when anti-glare is selected, The eyepoint can be set to a position where backlight does not enter.

  (8) The posture condition input means 23 includes an environment in which visibility is deteriorated, such as nighttime, rain, snow, fog, etc., as the external running environment, and the posture adjustment means 22 estimates the visibility deterioration degree A from the environment, and As the degree of deterioration A increases, the eye point moves forward and rises with respect to the vehicle. Therefore, the visibility of a nearby road surface can be improved as the visibility is worse.

  (9) The posture condition input means 23 includes an environment where a dredging operation is required for driving in response to environmental changes such as nighttime, rain, snow, fog, etc., and the posture adjusting means 22 requires a dredging operation. The degree of necessity B for the dredging operation B is estimated in order to estimate the degree B from the environment, and to increase the necessity B for the dredging operation, the height difference between the hip point and the movable floor 3 is reduced and the steering wheel 10 is moved backward with respect to the vehicle. The greater the is, the easier it is to perform a stepping operation, pedal operation, steering operation, and the like.

  (10) The posture adjustment means 22 is a driving posture when the target driver posture calculated from the posture condition input to the posture condition input means 23 is outside the range of a general driving posture set in advance. Since the drive amount of each drive means is limited so that the value falls within the above range, an excessive change in driving posture, interference with each member in the vehicle compartment, and the like can be prevented.
