However, the vehicle accelerator pedal operation device of this general structure applies a motor rotation and gear unit to reduce the rotational force and provide an additional power on the pedal, so that the time to reach the target power when providing the additional power is generated.
That is, referring to FIG. 1D, which is a graph of a pedal force of a vehicle acceleration pedal operating device having a general structure, when an extension rod of a rotating arm moves along a slot of a carrier and touches the end of the slot and interferes with it, a force for rotating the carrier is transmitted. Since the power is provided to the driver by the method of operating the power transmission member and the actuator, an error range B is generated in the process of transmitting the force between these components, thereby reaching the target power A to be provided.

In addition, in the case of the vehicle acceleration pedal operating device having a general structure, since a plurality of gears are applied, there is a fear that the deviation between the gears may occur, noise may occur due to the movement of the gear.

In addition, it is preferable that the upper end of the rotating arm is inclined, and more specifically, it is preferable that the upper end contact surface of the rotating arm has an inclination angle of 80 ° to 110 ° with the linear movement axis of the linear motor part.
In this case, the case where the contact surface of the upper end of the rotating arm and the linear moving shaft of the linear motor portion is 90 degrees may be the case that the force applied to the rotating arm by the rotating roller is maximum, but the linear motor portion performs linear motion, and the rotating arm rotates. Because of their movement, the inclination angle cannot be kept at 90 ° during their movement.
In other words, if both the linear motor portion and the rotary arm are in a linear motion, or if both rotational movements are performed, the linear motor portion and the rotary arm may be moved while maintaining the inclination angle at 90 °. Since the point of contact with each other varies with each movement, the angle of inclination cannot be continuously maintained at 90 ° during movement.
Therefore, in order to maximize the force exerted on the rotating arm by the rotating roller, it is preferable that the upper end contact surface of the rotating arm has an inclination angle of 80 ° to 110 ° with the linear movement axis of the linear motor part.

At this time, when a current is applied to the coil part, a magnetic force line is generated in the coil, and the coil guide is linearly moved (L-L direction) by the interaction of the generated magnetic force line with the first magnet part and the second magnet part. On the other hand, applying the current to the coil unit is the case that the driver uses the AAP system according to the present invention, the control of the application of current is possible through the control circuit unit for controlling the above-described linear motor unit, according to the current applied The coil guide may linearly move forward or backward in a space between the second magnet part and the first magnet part.
That is, when a current is applied to the coil, the rotary roller shaft and the rotary roller positioned in the coil guide are linearly moved by the linear motion of the coil guide. Since the operation of the linear motor is well known, a detailed description thereof will be omitted below.
4A is a view showing a state in which a driver drives without using the AAP system according to the present invention (hereinafter, referred to as a passive mode), and FIG. 4B shows the driver using the AAP system according to the present invention. This is a diagram showing a state in which driving is performed (hereinafter referred to as an active mode).
First, referring to FIG. 4A, when the pedal arm (not shown) is rotated counterclockwise by applying a force to the pedal pad (not shown), the
At this time, since FIG. 4A is the passive mode, no current is applied to the
In addition, when the force is removed from the pedal pad (not shown) for deceleration of the vehicle, the
That is, in the passive mode in which the driver operates without using the AAP system according to the present invention, since no current is applied to the linear motor unit, the rotary arm and the pedal arm have a rotational motion independent of the linear motor unit. The rotary roller and the rotary roller shaft move linearly along the direction of movement of the rotary arm.
Next, referring to FIG. 4B, when the pedal arm (not shown) is rotated counterclockwise by applying a force to the pedal pad (not shown) to rotate the vehicle, the rotary arm (2) is rotated about the
However, unlike in FIG. 4A, since FIG. 4B is an active mode, a current is applied to the
As a result, as the rotary roller portion linearly moves in the direction opposite to the rotational direction of the rotary arm, the linear motor portion transmits the pedal force to the rotary arm, and thus the driver transmits the pedal force provided by the linear motor portion through the pedal arm and the pedal. You will be delivered.
In this case, when the driver uses the AAP system, the driver may preset a speed for operating the AAP system. Therefore, when the speed of the vehicle becomes greater than or equal to the preset speed, the driver applies a constant current to the linear motor unit in the linear motor controller. As a result, the linear motor portion can linearly move.
In addition, when the force is removed from the pedal pad (not shown) for deceleration of the vehicle, the
4C is a diagram for explaining a passive mode assuming that a magnet part is not formed on the rotating arm.
First, in order to accelerate the vehicle, when the pedal arm (not shown) is rotated counterclockwise by applying a force to the pedal pad (not shown), as shown in FIG. 4A, the
Meanwhile, since FIG. 4C corresponds to the passive mode as shown in FIG. 4A, no current is applied to the
However, even if the force is removed from the pedal pad (not shown) for deceleration of the vehicle, it is assumed in the case of FIG. 4C that the magnet part is not formed on the rotating arm, and thus, the
Therefore, in the passive mode assuming that no magnet part is formed in the rotating arm, when the force is applied to the pedal pad and the force is removed again, the space Y between the
At this time, when the passive mode is changed to the active mode in a state where the space Y between the
Therefore, the vehicle acceleration pedal operating device according to the present invention forms the rotary roller with a metal material and forms the magnet portion in a predetermined region of the rotary arm, thereby allowing the rotary roller to be magnetized in the magnet portion in any of the passive mode and the active mode. By making a contact, ie, making a linear motor part contact a fixed area | region of a rotating arm, unnecessary discomfort by the collision of a rotating roller and a rotating arm can be improved.
5 is a graph of the power of the accelerator pedal operation device for a vehicle according to the present invention. In this case, in FIG. 5, the X axis represents an operating angle of the pedal, and the speed of the vehicle may increase according to the operating angle of the pedal, and the Y axis represents a load transmitted to the driver. In addition, area A indicates an area providing simple stepping force among loads transmitted to the driver, and area B indicates an area providing vibration among loads transmitted to the driver. However, the area providing the effort and the area providing the vibration are only examples, and the present invention is not limited thereto.
Referring to FIG. 5, it can be seen that the target effort to be provided in real time is reached without generating an error range in both the A and B regions.
That is, in FIG. 1d, which shows a graph of the pedal effort of a vehicle accelerator pedal operating device having a general structure, an error range B occurs in the process of transmitting forces between the components, until the target pedal A is provided. Although the response time is longer, in the present invention, since the linear motor unit directly transmits the turning force to the rotating arm, there is no separate configuration in which the force is transmitted while providing the turning force, thereby providing a real time without generating an error range. It can be seen that the target effort is reached.
Therefore, the vehicle accelerator pedal operation apparatus according to the present invention provides a direct power through the linear motor portion in contact with a predetermined region of the rotary arm, so that the target power can be reached without an error range.
Further, by making the rotary roller of the linear motor portion magnetically contact the magnet portion of the rotary arm, unnecessary discomfort caused by the collision of the rotary roller and the rotary arm can be improved.
While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
