Description

  The present invention relates to a movable pedal adjusting device for an automobile.

Conventionally, in an automobile, as shown in FIG. 21, the layout of a seat 200, a floor panel 201, and an accelerator pedal (or brake pedal) 202 is designed according to a standard occupant M.
However, there are physique differences among the occupants. For example, when an occupant L with a large physique or an occupant S with a small physique sits on the seat 200, the distance from the occupant to the accelerator pedal (or brake pedal) 202 is different. It is necessary to adjust the driving posture according to each physique.
For example, the above-described seat 200 includes a seat cushion 203, a seat back 204, a headrest 205, and a seat slide device (not shown), and the seat slide device is used for passengers L, M, and S seated on the seat cushion 203. The hip points P11, P12, and P13 are configured to be movable back and forth in a substantially horizontal direction. However, since the positions of the accelerator pedal 202 and the floor panel 201 are fixed, there are the following problems.

That is, the occupants L, M, and S operate the accelerator pedal 202 with scissors on the floor mat 207 laid on the top surface of the floor panel 201. In this case, there is no major problem for the large occupant L and the medium sized standard occupant M, but in the case of the occupant S with a small physique, the foot does not reach the accelerator pedal 202 sufficiently, so the floor mat 207 When the accelerator pedal 202 is operated with a heel on, the accelerator pedal 202 is stepped on at the toe portion, and when the accelerator pedal 202 is depressed, the accelerator pedal 202 moves in the forward direction of the vehicle. Becomes difficult.
In order to solve such problems, it is necessary for the occupant S having a small physique to sit at the front position with respect to the seat cushion 203 and to operate the accelerator pedal 202 after the heel is once lifted from the floor mat 207 surface. As a result, the driving posture had to be unnatural for passengers with a small physique.

  Therefore, it is desired to be able to adjust the seat position and pedal position according to the occupant's physique. For example, in Patent Document 1 below, the pedal position is fixed at a specific position (for example, the maximum depression position). After that, it is disclosed that the seat position and the pedal position corresponding to the occupant's physique are adjusted in conjunction by the adjusting operation means, and according to such Patent Document 1, the optimum according to the occupant's physique is disclosed. It is possible to obtain a correct seat position and pedal position.

However, according to Patent Document 1 described above, there are the following problems.
That is, according to Patent Document 1, when the pedal position is adjusted, the foot must be lifted and held while it is moved from the maximum depressed position where the pedal is fixed to the desired position until it contacts the occupant's foot. There is a problem that an occupant is burdened during the adjustment.

Is set at each position a, d, h, and when the physique is a standard occupant M, it is set at each position b, f, i, and when the physique S is small, each position c, g, j Set to

In the next step S4, it is determined whether or not the accelerator pedal adjustment switch 73 is ON.
When YES is determined in the step S4, the process proceeds to a step S5, where the interlocking state between the accelerator pedal 9 and the engine throttle valve (not shown) is once shut off by a not-shown interlocking cutoff means, and the details are shown in FIG. The reference position of the accelerator pedal 9 indicating is adjusted.
In step S5, the interlock between the accelerator pedal 9 and the throttle valve (not shown) of the engine is cut off because the throttle valve is opened and closed as the reference position of the accelerator pedal 9 described later is adjusted, and undesired engine fluctuations occur. This is to suppress this.

If NO is determined in step S4, the process proceeds to step S6 to determine whether or not the brake pedal adjustment switch 74 is turned on.
When YES is determined in the step S6, the process proceeds to a step S7, and the reference position adjustment of the brake pedal 51 whose details are shown in FIG. 10 is performed.

(Adjustment of accelerator pedal reference position)
FIG. 9 is a flowchart showing details of step S5, that is, reference position adjustment of the accelerator pedal 9. First, in step S501 of FIG. (See a in FIG. 11)

  In step S502, the current position Asen detected by the accelerator pedal position sensor 71, the previously detected temporary storage value Atemp, and the reference position Amem are initialized.

In step S503, the current position Asen detected by the accelerator pedal position sensor 71 is read.
In step S504, it is determined whether the current position Asen read in step S13 is not 0, that is, whether the accelerator pedal 9 is depressed.
When YES is determined in the step S504, the process proceeds to a step S505, and it is determined whether or not the current position Asen and the temporary storage value Atemp match.
When YES is determined in the step S505, the process proceeds to a step S506, and the current position Asen is stored as a temporary storage value Atemp.

In step S507, it is determined whether or not a predetermined time has elapsed since the current position Asen and the temporary storage value Atemp coincided.
When it is determined NO in step S507, the process proceeds to step S508 and the timer T is counted up.
If YES in step S507, that is, if the accelerator pedal 9 is kept constant for a predetermined time (see b in FIG. 11), the process proceeds to step S509, where the current position Asen is stored as the reference position Amem. 11c, the motor 70 is driven so that the depression start position of the accelerator pedal 9 coincides with the reference position Amem.
After storing the reference position Amem, the interlocking cutoff between the accelerator pedal 9 and the engine throttle valve (not shown) is released.

  Then, as shown in FIG. 12, the motor 70 is set and driven by setting the set reference position Amem as the reference position of the accelerator pedal 9, that is, the depression start position for starting the depression of the accelerator pedal.

(Brake pedal reference position adjustment)
FIG. 10 is a flowchart showing the adjustment of the reference position of the brake pedal 51. The adjustment of the reference position of the brake pedal 51 is merely the replacement of the target pedal from the accelerator pedal 9 to the brake pedal 51, and the reference position adjustment itself. Is exactly the same as that of the accelerator pedal 9, and a detailed description thereof will be omitted.
Then, as shown in FIG. 13, the motor 80 is set and driven by setting the set reference position Bmem as the reference position of the occupant's brake pedal 51, that is, the depression start position where the depression of the brake pedal 51 is started. .

As described above, according to the first embodiment, the position Aaen of the accelerator pedal 9 when the passenger is depressed to a desired position and maintained for a predetermined period is stored as the reference position Amem, and the accelerator pedal 9 is depressed. Since the motor 70 is driven so that the start position coincides with the reference position Amem, there is no need to wait for the accelerator pedal 9 to move to the reference position Amem, and the burden on the occupant is suppressed when the position of the accelerator pedal 9 is adjusted. The position of the accelerator pedal 9 can be adjusted to an optimal position according to the occupant's physique.
Further, the brake pedal 51 can provide the same effect as the accelerator pedal 9.

Here, when adjusting the position of each pedal 9, 51, it is desirable to maintain the posture of the occupant. However, when an operation unit for adjusting the position of each pedal 9, 51 is provided on the instrument panel or the like, It is necessary to extend the arm to the operation unit for operation, and the driving posture is destroyed at that time.
On the other hand, in the first embodiment, when the depression position of the accelerator pedal 9 is maintained constant for a predetermined period, the position of the accelerator pedal 9 at that time is stored as the reference position Amem, and the depression of the pedals 9 and 51 is started. Since the motor 70 is driven so that the position coincides with the reference position Amem, the depression start position of each pedal 9, 51 can be adjusted only by operating the accelerator pedal 9, that is, only by operating the foot of the passenger. The pedals 9 and 51 can be adjusted while maintaining the driving posture of the occupant.

  In addition, when the pedals 9 and 51 are adjusted, the initial positions of the pedals 9 and 51 are set to positions that are most accessible to the occupant. The pedal operability of the pedals 9 and 51 for determining the pedal can be ensured, and the depression start position of the pedals 9 and 51 is adjusted to the optimum position according to the occupant's physique while suppressing the burden on the occupant. Can do.

It is a figure which shows a state.

  FIG. 14 is a control block diagram relating to the second embodiment, but the second embodiment is different from the first embodiment in that instead of the accelerator pedal adjustment switch 73 and the brake pedal adjustment switch 74, one adjustment switch 75 for adjusting both pedals is used. Only the point that the detection signal is input to the control unit 100 is the same as in the first embodiment.

(Basic motor control)
In step S21 in FIG. 15, detection signals from the seat position detection sensor 80, the accelerator pedal position sensor 71, the brake pedal position detection sensor 72, and the adjustment switch 75 are read.
In step S22, the motor 60 is driven and controlled to reach the movable floor position corresponding to the seat position read in step S21, and in step S23, the accelerator pedal 9 and the brake corresponding to the seat position read in step 21 are controlled. The motors 70 and 80 are adjusted so that the pedal 51 is located.
That is, as described above, the relationship between the position of the movable floor 10 and the depression start position of the pedals 9 and 51 is adjusted based on the position of the seat cushion 1 adjusted according to the occupant's physique, and the occupant L having a large physique. Is set at each position a, d, h, when the physique is a standard occupant M, it is set at each position b, f, i, and when the physique S is small, each position c, g , J.

In subsequent step S24, it is determined whether or not the adjustment switch 75 is ON.
When YES is determined in the step S24, the process proceeds to a step S25, where the interlocking state between the accelerator pedal 9 and the engine throttle valve (not shown) is once shut off by a not-shown interlocking cutoff means, and the details are shown in FIG. The reference position of the accelerator pedal 9 and the brake pedal 51 indicating is adjusted. Moreover, when it determines with NO by step S24, it returns.
It should be noted that in step S5, the interlock between the accelerator pedal 9 and the engine throttle valve (not shown) is cut off as the throttle valve is opened and closed as the reference position of the accelerator pedal 9 described later is adjusted, as in the first embodiment. This is to suppress the occurrence of a serious engine fluctuation.

First, in step S251 of FIG. 16, the accelerator pedal 9 and the brake pedal 51 are occupants. Is moved to the initial position where it is most accessible. Further, at this time, the motors 70 and 80 are free, and can be depressed beyond the operation stroke from the initial position.
In step S252, as shown in FIG. 17, when the accelerator pedal 9 and the brake pedal 51 are moved to the initial position that is most accessible to the occupant, the difference between the initial position and the maximum depression position for each pedal 9, 51, That is, the operation strokes Aconst and Bconst are set.
In step S253, the current position Asen detected by the accelerator pedal position sensor 71, the already stored reference position Amem, the current position Bsen detected by the brake pedal position sensor 72, and the already stored reference value Bmem are used. initialize.

In step S254, the current position Asen of the accelerator pedal 9 is read, and in step S255, it is determined whether the current position Asen read in step S254 is not 0, that is, whether the accelerator pedal 9 is depressed.
When YES is determined in the step S255, the process proceeds to a step S256 so as to read the current position Bsen of the brake pedal 51.
In step S257, it is determined whether the position of the brake pedal 51 is not 0, that is, whether the brake pedal 51 is depressed.
When it is determined YES in step S257, that is, when the brake pedal 51 is depressed after the accelerator pedal 9 is depressed to the maximum depression position, the depression start position for starting depression from the maximum depression position It is determined that it is necessary to determine a reference position, and the process proceeds to step S258.
If NO is determined in step S257, the process returns to the step before S256.
After storing the reference position Amem, the interlocking cutoff between the accelerator pedal 9 and the engine throttle valve (not shown) is released.

  In step S258, the reference position Amem of the accelerator pedal 9 is determined. That is, as shown in FIG. 17, the reference position Adem is determined by subtracting the difference Aconst set in step S252 from the current position Asen corresponding to the maximum depression. The position Amem is determined, and the motor 70 is driven so that the position of the accelerator pedal 9 coincides with the reference position Amem.

If NO is determined in step S255, the process proceeds to step S259, and the current position Bsen of the brake pedal 51 is read.
In step S260, it is determined whether or not the position of the brake pedal 51 is not 0, that is, whether or not the brake pedal 51 is depressed.
When YES is determined in the step S260, the process proceeds to a step S261 so as to read the current position Amem of the accelerator pedal 9.
In step S262, it is determined whether or not the position of the accelerator pedal 9 is not 0, that is, whether or not the accelerator pedal 9 is depressed.
When YES is determined in step S262, that is, when the accelerator pedal 9 is depressed after the brake pedal 51 is depressed to the maximum depression position, the depression start position for starting depression from the maximum depression position It is determined that it is necessary to determine a reference position, and the process proceeds to step S263.
If NO is determined in step S262, the process returns to before step S261.

  In step S263, the reference position Bmem of the brake pedal 51 is determined. That is, as in the case of the accelerator pedal 9, the reference position Bmem that becomes the depression start value by subtracting the difference Bconst set in step S252 from the current position Bsen corresponding to the maximum depression position. At the same time, the motor 80 is driven so that the position of the brake pedal 51 matches the reference position Amem.

As described above, according to the second embodiment, the reference position Amem in which the value obtained based on the position Asen of the accelerator pedal 9 and the difference Aconst when the occupant is depressed to the maximum depression position corresponds to the depression start position. Since the motor 70 is driven so that the depression start position of the accelerator pedal 9 coincides with the reference position Amem, there is no need to wait for the accelerator pedal 9 to move to the reference position Amem. In the adjustment, the position of the accelerator pedal 9 can be adjusted to an optimum position according to the occupant's physique while suppressing the burden on the occupant.
Further, the brake pedal 51 can provide the same effect as the accelerator pedal 9.

Here, when adjusting the position of each pedal 9, 51, it is desirable to maintain the posture of the occupant. However, when an operation unit for adjusting the position of each pedal 9, 51 is provided on the instrument panel or the like, It is necessary to extend the arm to the operation unit for operation, and the driving posture is destroyed at that time.
In contrast, in the second embodiment, when the brake pedal 51 is depressed after the accelerator pedal 9 is depressed to the maximum depression position, a reference position Amem corresponding to the depression start position is obtained from the maximum depression position and stored. Since the motor 70 is driven so that the depression start position of each pedal 9, 51 coincides with the reference position Amem, only the operation of the accelerator pedal 9 and the brake pedal 51, that is, only the operation of the occupant's foot, The stepping start position of 51 can be adjusted, and the pedals 9 and 51 can be adjusted while maintaining the driving posture of the occupant.

  In addition, when the pedals 9 and 51 are adjusted, the initial positions of the pedals 9 and 51 are set to positions that are most accessible to the occupant. The pedal operability of the pedals 9 and 51 for determining the pedal can be ensured, and the position of the pedals 9 and 51 can be adjusted to the optimal position according to the occupant's physique while suppressing the burden on the occupant. .
