Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an accelerator pedal device having an accelerator sensor for detecting the depression position of an accelerator pedal and an output adjusting method thereof.

[0002]

2. Description of the Related Art In recent years, an accelerator pedal device mounted on a vehicle or the like has an accelerator sensor which is provided so as to interlock with a depression operation of the accelerator pedal and detects a depression position of the accelerator pedal. That is, the output value (electrical signal) corresponding to the accelerator pedal depression position
Is being generated. Also, on the throttle side that is provided in the engine (power unit) and instructs the engine to output,
A drive device for driving a throttle such as a motor is attached. Then, an electric throttle system is used in which the drive device is drive-controlled based on the output value from the accelerator sensor. Specifically, as the accelerator pedal depression position,
By generating a predetermined output value from the accelerator sensor that corresponds to the fully closed position (before the accelerator pedal is depressed) to the fully opened position (the default depressed position from the fully closed position), the operator's feeling of stepping operation and engine operation Corresponds to the state (output).

[0003]

However, in the conventional accelerator pedal device, there is a difference between the depression position of the accelerator pedal and the output value from the accelerator sensor due to variations in mounting of the accelerator sensor on the accelerator pedal. It is easy to occur. That is, a predetermined output value is not output from the accelerator sensor for a predetermined accelerator pedal depression position (fully open position, fully closed position, etc.).

Further, as the accelerator pedal depression position, there is a depression position set outside the normal depression range from the fully closed position to the fully opened position. For example, there is a case where a kick down stepping position is provided at a further stepping position after reaching the fully open position from the fully closed position. The kick-down depression position is a position where the accelerator pedal is depressed when more output than the engine output set to the fully open position is required. Specifically, for example, when an output value indicating the kick down depression position is input, the gear ratio of the transmission is changed to increase the output.

Therefore, a stepping force operating means for providing a change in the stepping operation force that can be recognized by the operator is provided so that the operator can feel the kickdown stepping position. Then, a predetermined output value from the accelerator sensor corresponding to the change in the stepping operation force is obtained.
However, the stepping force operating means is additionally arranged on the accelerator pedal. Therefore, a change is likely to occur between the change in the stepping operation force and the output value output from the accelerator sensor at that time. As described above, it is difficult to obtain a predetermined output value from the accelerator sensor corresponding to the depression position of the accelerator pedal, which deteriorates the operator's feeling of depressing operation, which is a problem.

Even in the case of an accelerator sensor that detects any one of the fully closed position, the fully open position, and the kick down depressed position as the depressed position of the accelerator pedal, the fully closed position, the fully opened position, and the kick down depressed position described above. If the state of the accelerator pedal position to switch to etc. does not match the information (signal) that informs that the accelerator pedal position has been entered, the operator's feeling of stepping and the output state of the engine do not match and the operator's feeling of stepping is deteriorated So it is a problem.

In view of the above points, an object of the present invention is to obtain a predetermined output value corresponding to a predetermined depression position of the accelerator pedal even when the mounting position of the accelerator sensor or the like is deviated. An object of the present invention is to provide an accelerator pedal device and an output adjusting method thereof.

Another object of the present invention is to provide an accelerator pedal device capable of adjusting the output fluctuation due to the displacement of the mounting position of the accelerator sensor or the like by an electric circuit means, facilitating the output adjustment and improving the output adjustment accuracy. It is to provide the output adjustment method.

[0009]

In order to solve the above-mentioned problems, according to the accelerator pedal device according to claim 1 of the present invention, when the accelerator sensor is adjusted to a predetermined depression position of the accelerator pedal, The present invention is characterized in that it has a function of adjusting to a predetermined output value indicating that it is this predetermined stepping position, and that it has an output adjusting means for outputting the adjusted output value.

It has an adjustable function and outputs the adjusted output value. Therefore, it is possible to provide an accelerator pedal device that does not worsen the operator's feeling of stepping on the pedal.

Prepare The output adjusting means has a function of adjusting to a predetermined output value indicating that the accelerator pedal is at the stepping force change point, and outputs the adjusted output value. It is characterized by

As a result, the output adjusting means has a function of adjusting to a predetermined output value indicating a stepping force change point and outputs the adjusted output value, so that the operator's feeling of stepping operation is deteriorated. It is possible to provide an accelerator pedal device that does not have a problem.

According to the third aspect of the present invention, the stepping force operating means has an abutting member that abuts a part of the accelerator pedal when the accelerator pedal is stepped on to a predetermined position. Then, the abutment member is deformed from a predetermined position by further depression of the accelerator pedal to generate an additional reaction force and gives a depression stroke to the accelerator pedal. The contact member is deformed along with the stepping stroke, and when the amount of deformation reaches a predetermined amount, the additional drag force is released and the contact force is rapidly reduced.

As a result, the above-mentioned stepping force operating means abuts on a part of the accelerator pedal to give an additional reaction force to the stepping force of the accelerator pedal, and then the additional reaction force is released, thereby depressing the accelerator pedal. It can give a sense of moderation. Further, since it is a mechanism for generating an additional drag force due to contact with the accelerator pedal, the depression force operating means does not affect the return force of the accelerator pedal after giving this moderation feeling. Therefore, it is possible to provide a stepping force operating means capable of smoothly performing the steps from stepping on to returning.

The output adjustment can be facilitated and the output adjustment accuracy can be improved.

According to a seventh aspect of the present invention, the predetermined depression position includes a fully closed position and a fully opened position.

As a result, the output value at the fully closed position, which is the accelerator pedal depression position, and at the fully open position can be adjusted to the predetermined output value.

According to the eighth aspect of the present invention, a preset output value storage unit for storing a preset output value corresponding to a preset depression position of the accelerator pedal is provided, and the preset output value storage unit stores the preset output value in advance. A data input indicating device for modifying the information for obtaining the predetermined output value is connected to the accelerator sensor. The data input instructing device outputs the output value output from the output unit and the default output value stored in the default output value storage unit when the corrected output value storage unit is aligned with the default depression position of the accelerator pedal. It is characterized in that and are stored in association with each other.

It is characterized in that it is transmitted to and stored in the corrected output value storage means.

As described above, since the default output value storage unit is provided inside the accelerator sensor, when the default output value stored in the default output value storage unit is adapted to each specification as different data for each vehicle type, The default output value data stored in the output value storage unit will not be confused. That is, it is possible to accurately and promptly store the output value output from the output unit and the default output value stored in the default output value storage unit in association with each other.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an accelerator pedal device and a method for manufacturing the same according to an embodiment of the present invention will be described in detail with reference to the drawings.

According to the present invention, in an accelerator pedal device mounted on a vehicle or the like and having an accelerator sensor for detecting a depression position of an accelerator pedal, a predetermined output value from the accelerator sensor corresponding to a predetermined depression position of the accelerator pedal is displayed. The present invention relates to an accelerator pedal device that can be obtained and an output adjusting method thereof.

The structure and schematic operation of the accelerator pedal device 1 will be described with reference to FIGS. 1 and 2. FIG. 1 is a process diagram showing a step of stepping on the accelerator pedal device 1 of the present invention. FIG. 1 (a) shows a fully closed position of the accelerator pedal 2, and FIG. FIG. 1C shows a contact start position with the contact member 3, and FIG. 1C shows a state where the accelerator pedal 2 is further stepped on from the state of FIG. 1B to a fully open position, and FIG. It shows a state in which the accelerator pedal 2 is further stepped on from the state of 1 (c) and the additional reaction force by the contact member 3 at the kick down stepping position is released.
FIG. 2 is an explanatory diagram showing the relationship between the step of depressing the accelerator pedal 2 of the present invention, the pedal effort, and the output value of the accelerator sensor 6.

The accelerator pedal device 1 described below
Has a kick-down depression position other than the normal depression range in which the accelerator pedal 2 is normally operated to be depressed from the fully closed position to the fully opened position. This kick-down depression position is provided at a further depression position after the full-closed position is reached to the fully-opened position, and provides more output than the output of the engine (not shown) set at the fully-opened position of the accelerator pedal 2. This is the position to step on when seeking. Specifically, for example, when an output value indicating that the pedal is depressed to the kick-down depression position and the pedal is depressed, the gear ratio of the transmission is changed so that the output is increased. Further, the kick-down stepping position is not normally used, but a stepping force operating means for giving a change in stepping operation force that the operator can recognize so that the operator can feel that the kick-down stepping position is reached. Will be described later).

FIG. 1 (a) shows a state before the accelerator pedal 2 is depressed by the operator, which is a fully closed position of the accelerator pedal 2 shown by point (a) in FIG. The accelerator pedal 2 is fixed to an indicator shaft 5 provided on the indicator member 4 and is rotatable about the indicator shaft 5 as a fulcrum. The pointing member 4 includes an abutting member 3 formed of an elastically deformable leaf spring or the like.
Is fixed. This leaf spring is made of metal or resin material. Further, an accelerator sensor 6 fixed to the indicating member 4 is arranged on the indicating shaft 5, and the accelerator sensor 6 generates an output value (electric signal) corresponding to the depression position of the accelerator pedal 2.

Although not shown, a return spring or the like as a return force generating portion is provided so that the accelerator pedal 2 can be returned to the fully closed position which is the initial position of depression when the depression is released after the depression of the accelerator pedal 2. It is provided. That is, the accelerator pedal 2 is moved from the fully closed position to the position shown in FIG.
(A) When the pedal is depressed in the middle F direction, a pedaling force is generated on the accelerator pedal 2 to maintain the position of the accelerator pedal 2 at each position. A characteristic line L1 in FIG. 2 shows the characteristics of the accelerator pedal 2 position and the accelerator pedal 2 pedaling force by the returning force generating portion.

FIG. 1 (b) shows a state in which the accelerator pedal 2 is stepped on and a part of the accelerator pedal 2 and the contact member 3 start contact, and the accelerator shown at point (b) in FIG. This is the stepped position of the pedal 2. The contact member 3 generates an additional reaction force (additional pedaling force) in addition to the pedaling force of the accelerator pedal 2 by the above-described return force generating unit starting from the position of the point (b).

In FIG. 1C, the accelerator pedal 2 is further depressed from the state of FIG. 1B, and the contact member 3 is deformed while abutting on a part of the accelerator pedal 2 to be deformed.
After giving a slight stepping stroke to the
Of the stepped portion 4a provided at the end and the deformable end portion 3 on the contact member 3 side
It shows a state in which a is locked. This locked state is shown at point (c) in FIG. This point is for accelerator pedal 2
Although it is in the middle of its effective stroke (before the fully open position),
This is a position where a command for 100% throttle opening is transmitted to the throttle side that instructs the engine to output.

In FIG. 1 (d), the accelerator pedal 2 is further depressed from the state of FIG. 1 (c), and the contact member 3 is deformed while the stepped portion 4a and the end portion 3a are kept locked. After the additional drag is increased, the amount of deformation reaches a predetermined amount and the locked state between the step portion 4a and the end portion 3a is released. In detail, the end 3a is disengaged from the step 4a, the end 3a is released from the step 4a, and the additional reaction force applied to the accelerator pedal 2 is released. Point P in FIG. 2 indicates the peak point (maximum point) of the additional drag force exerted by the contact member 3, and point (d) in FIG. 2 indicates the state in which the additional drag force exerted by the contact member 3 has been released. Thus, as shown in FIG.
The contact member 3 capable of generating the point, the point P, and the point (d) constitutes the stepping force operating means according to claim 3.

Since the above-mentioned contact member 3 is a mechanism for generating an additional reaction force by contacting with the accelerator pedal 2, the contact member is applied to the return force of the accelerator pedal 2 after the additional reaction force is generated. 3 has no effect. Therefore, it is possible to provide a stepping force operating means capable of smoothly performing the steps from stepping on to returning.

The kick-down depression position described above is shown in FIG.
It is set at a position on the way from the P point in the middle to the (D) point in FIG. That is, the operator generates an additional reaction force by depressing the accelerator pedal 2 to generate an additional reaction force from a position after 100% of the throttle opening to a point P and a point (d) in FIG. To recognize. By recognizing this additional drag, the operator can be given a sense of moderation in operating the accelerator pedal 2. A kick-down depression position is provided immediately after the passage of point P, and this position is shown at point A in FIG. This is the kick-down position A
An output value (electrical signal) corresponding to the point position is transmitted from the accelerator sensor 6 to an output control unit (not shown) of the engine or the like, and the engine is controlled to have a high output. In other words, the recognition of the moderation sensation and the change point for increasing the output of the engine are made to correspond to each other, and the operator's feeling of stepping operation is improved.

Here, when outputting an output value indicating the kick-down depression position, which is the predetermined depression position of the accelerator pedal 2, there are variations in attachment of the accelerator sensor 6 to the accelerator pedal 2, and the accelerator pedal 2 and the abutting member. The relative position with respect to No. 3 and the like occur, and due to these, a deviation easily occurs between the kick down depression position and the output value from the accelerator sensor 6 corresponding to the kick down depression position. That is, the accelerator sensor 6 does not output the predetermined output value at the predetermined kick-down depression position. The L2 characteristic line in FIG. 2 is a characteristic of the output value output from the accelerator sensor 6 with respect to the depression position of the accelerator pedal 2, and is between the output value from the accelerator sensor 6 corresponding to the kickdown depression position. The state where the deviation has occurred is shown. Therefore, an electric circuit means is added that uses the output from the accelerator sensor 6 as it is and corrects the output to a predetermined output value according to a predetermined depression position. That is, the output adjusting means described below is used to adjust from the L2 characteristic line in FIG. 2 to the L3 characteristic line in FIG. 2 so as to correspond to the perception of the moderation sensation and the change point to increase the output of the engine. I was allowed to.

FIG. 3 is a block diagram showing the output adjusting means 10. After the accelerator sensor 6 is mounted on the accelerator pedal 2, an external device is connected to the accelerator sensor 6 in order to electrically correct the mounting positions of both. Then, the apparent output of the accelerator sensor 6 is adjusted. It is mainly composed of an on-vehicle accelerator pedal device 1, a pedal position measuring means 13 which is an external device, a data input instructing device 14 and the like, and its output is adjusted before shipment of the accelerator pedal device or during vehicle inspection after shipment. It As shown in FIG. 3, the accelerator sensor 6 includes an output unit 11 that generates an output corresponding to the depression position of the accelerator pedal 2, and a corrected output value storage unit 12 (described later). This output unit 11 is
At least the fully closed position, the fully open position, and the kick down position of the accelerator pedal 2 are detected and an output corresponding to each position is generated. The structure is composed of a non-contact mechanism body that changes the output generated by the non-contact principle when the accelerator pedal 2 is depressed to change the depression position of the accelerator pedal 2.

Of course, the structure may be such that the position of each accelerator pedal 2 is detected and output continuously.
Then, in the present embodiment, the Hall element method is used as the non-contact mechanism. The non-contact mechanism (Hall element type) stabilizes the output from the output unit 11 even if the non-contact mechanism is arranged in the environment of the accelerator pedal 2 that is frequently depressed and has a large impact degree of depression. In addition to the Hall element method, a magnetoresistive element method or a differential transformer method may be used. These non-contact mechanism bodies can easily obtain the output linearity of the output value with respect to the depression position of the accelerator pedal 2 and can be configured compactly, which contributes to downsizing of the accelerator sensor 6.

The corrected output value storage means 12 stores the output value output from the output unit 11 when the accelerator pedal 2 is adjusted to a predetermined depression position such as a fully closed position, a fully opened position, and a kick down position. A default output value storage unit (described later) is stored in association with a default output value. This memorizing step (adjusting step) is performed on the accelerator pedal device 1 in which the accelerator sensor 6 and the abutting member 3 are assembled before manufacturing and shipping, with respect to the accelerator pedal device 1, which is an external device, and pedal input measuring means 13 and a data input instruction. This is done by connecting the device 14. In addition to this, when the mounting position of the accelerator sensor 6 or the like again occurs after shipping,
It is also possible to readjust the relationship between the output value and the default output value.

The pedal position measuring means 13 is interlocked with the accelerator pedal 2 and is rotated in synchronism with the accelerator sensor 6 to measure a continuous stepping angle in the process of stepping on the accelerator pedal 2 from the fully closed position. It has a function and a stepping torque measuring function capable of measuring the stepping force of the accelerator pedal 2. Then, the data 13a obtained from both functions is transmitted to the data input instruction device 14. That is, the data 13a transmitted from the pedal position measuring means 13 can specify the depression position of the accelerator pedal 2. For example, the kick-down depression position (A in FIG. 2)
When specifying the point), the point B in FIG. 2 is specified by the torque measuring function. After that, the accelerator pedal 2 is depressed by the amount of the angle from the point A to the point B calculated from the design data by using the angle measurement function, and the point A position is specified.

The data input instructing device 14 is internally provided with a preset output value storage section 15 for storing a preset output value corresponding to a preset depression position of the accelerator pedal 2. That is,
The data input instructing device 14 can specify the predetermined pedaling position of the accelerator pedal 2 from the pedaling angle data and the pedaling torque data received from the pedal position measuring means 13. Therefore, at the time when the accelerator pedal 2 is stepped on and the predetermined stepped position of the accelerator pedal 2 is specified, the default output value corresponding to this stepped position stored in the default output value storage unit 15 and the time when this stepped position is set. Correspond with the output value 11a output from the output unit 11,
Both data 14a are transmitted and stored in the corrected output value storage means 12.

The accelerator sensor 6 having the corrected output value storage means 12 in which the data 14a is stored has an output value 11b which is output from the output section 11 to the corrected output value storage means 12 when the accelerator pedal 2 reaches a predetermined depressed position. (Fig. 2
The stored default output value 12a ((f) in FIG. 2) is derived from (e) and is output.

FIG. 4 shows an example of data stored in the corrected output value storage means 12, in which the output value (accelerator sensor raw output) 11b at the kick down depression position is 3.1D.
C. With respect to V, 3.5 DC.
It is adjusted to V.

As described above, the accelerator pedal device 1 having the corrected output value storage means, when the accelerator pedal device 1 is adjusted to the predetermined depression position of the accelerator pedal, has a predetermined output value indicating that it is at the predetermined depression position. Can be stabilized and output. As a result, the predetermined output value is used as a signal to change the gear ratio of the transmission, for example, so that the operator's feeling of stepping operation and the operating state (output) of the engine are made to correspond to each other. I am allowed to.

When the accelerator sensor 6 has a structure for continuously detecting the fully open position and the position from the fully closed position to the fully open position in addition to the fully closed position and the kick down position, a large number of stepped positions You may make it memorize | store the output of the output part 11 and predetermined output value corresponding to. Also,
As the data that can be stored, a format in which the deviation from the output value is stored instead of storing the default output value itself may be used.

(Modification) The output adjusting means 10 shown in FIG.
May be configured as the output adjusting means 20 shown in FIG. The output adjusting means 20 is configured such that the output adjusting means 10 has the predetermined output value storage unit 15 integrated with the accelerator sensor 6.
Specifically, the accelerator sensor 6 has a preset output value storage unit 15 for storing a preset output value corresponding to a preset depression position of the accelerator pedal 2, and a corrected output value storage unit 15 stores the corrected output value via the preset output value storage unit 15. A data input instructing device 14 for correcting information for obtaining a predetermined default output value to be stored in the means 12 is connected to the accelerator sensor 6, and the data input instructing device 14 causes the default pedal output 2 to the default output value storage unit 15. The output value output from the output unit 11 when it is adjusted to the predetermined stepping position of No. 3 and the default output value stored in the default output value storage unit 15 are associated with each other, and the associated data is stored as the default output value storage. From the unit 15 to the corrected output value storage means 12
It is configured so that it is transmitted to and stored in. The relationship between the data input instructing device 14 and the pedal position measuring means 13 is the same as in the above-described embodiment.

That is, the data input instructing device 14 in the output adjusting means 20 causes the default output value storage unit for the accelerator sensor 6 at the time when the accelerator pedal 2 is depressed and the predetermined depression position of the accelerator pedal 2 is specified. The default output value corresponding to the stepped position stored in 15 and the output value 11a output from the output unit 11 when the stepped position is matched are made to correspond to each other, and both data are stored in the corrected output value storage means 12. The signal 14a is sent to instruct to transmit and store 15a.

With the configuration of the output adjusting means 20, if the preset output value corresponding to the preset depression position of the accelerator pedal 2 stored in the preset output value storage unit 15 is adapted to various specifications which are different for each vehicle type, for example. , The data stored in the default output value storage unit 15 is not confused,
The output value output from the output unit 11 and the default output value stored in the default output value storage unit 15 can be accurately and quickly stored in association with each other.

In carrying out the present invention, the predetermined pedal depression position of the accelerator pedal 2 may be, for example, the accelerator pedal 2 other than the above-described kick-down depression position (point A).
May be in the fully closed position (position not stepped on). By transmitting the predetermined output value indicating the fully closed position from the output unit 11 to the engine side, the idle rotation on the engine side is accurately operated at the set rotation. Further, since this idle rotation corresponds to the fully closed position of the accelerator pedal 2, the rattling of the output is eliminated without deviating the depression of the accelerator pedal 2 from the increase in the output of the engine. In other words, the predetermined depression position of the accelerator pedal 2 is set variously such as the fully open position of the accelerator pedal 2 so as to make the correspondence with the output generation side on the engine side accurate. An example of data stored in the corrected output value storage means 12 is shown in FIG. 4, and the output value (accelerator sensor raw output) 11b at the fully closed position is 0.8 DC. The default output value 12a is set to 1.
0DC. It is adjusted to V. Further, both output values 11b and 12a are shown in (g) and (h) of FIG. 2, respectively.

In carrying out the present invention, the contact member 3
Is an elastically deformable leaf spring or the like, but the abutting member 3 for generating this moderation suffices to generate a moderation sensation when the accelerator pedal 2 is depressed, and various shapes and configurations are devised.
