Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a driving member such as a joystick used for driving a vehicle and a grip portion for the driving member.

[0002]

2. Description of the Related Art There is known a vehicle in which a joystick (driving operator) such as a stick type provided in a driver's seat is used instead of a steering wheel to perform a driving operation. In such a vehicle, for example, when the driver operates the joystick left and right, the steered wheels are steered to the left and right, and when the joystick is operated back and forth, acceleration / deceleration operation is performed on the vehicle. An operation reaction force is applied to this joystick by a spring, a motor, etc., so that the steering wheel returns to the neutral position by the self-alignment torque, and the accelerator pedal and brake pedal are returned to the zero position by the return spring. The joystick also returns to the neutral position when you release it. This reaction force facilitates the driving operation with the joystick, and gives the driver a feeling that the driving operation is being performed. Further, it becomes easier to perform a delicate driving operation as compared with the case where there is no reaction force.

Most joysticks are operated with one hand. When operating the joystick with one hand, there is a direction in which the joystick is easy to operate (tilt) due to the characteristics of the human body, not to mention the explanation. Specifically, in the case of a general joystick 51 having a grip portion 52 as shown in FIG. 7, an operation of moving the joystick 51 toward the center of one's body, in other words, an operation of moving the joystick 51 to the palm side (tilting). The operation) is easier than the operation of moving it to the back side of the hand. Further, the operation of moving the joystick 51 to the palm side can be performed even with the palm open, but the operation of moving the joystick 51 to the back side of the hand does not grip the grip portion 52 or hook the grip portion 52 with the thumb. And cannot be operated. From this point as well, the operation of the joystick 52 on the back side of the hand is harder to perform than the operation on the palm side. Therefore, it is necessary to take some measures.

To solve this problem, for example, Japanese Patent Laid-Open No. 11-1
Japanese Patent No. 92960 discloses that "the operation in the direction away from the center of the body of the driver is smaller than the operation in the direction toward the center of the body of the driver from the arm operating the joystick. A driving operation device characterized by having operation characteristic changing means for changing the characteristic "is disclosed. Further, there is disclosed "a technique in which a lever-shaped portion of a joystick held by an occupant is provided with a protrusion-shaped push-down portion for facilitating input of a vertically downward force".

[0005]

However, the driving operation device having the above-mentioned operation characteristic changing means requires a processing device for performing a complicated calculation. For this reason, there is a concern about a problem of reduced reliability and a cost problem. Also, regarding the technology to provide a protruding push-down part on the joystick,
I need a separate joystick support mechanism,
The operability of the joystick cannot be improved simply by providing the protrusion-like push-down portion. Therefore, there is a problem in reliability and cost due to the complicated supporting mechanism.

Therefore, it is a main object of the present invention to solve the problems of reliability and cost, and to provide a driving manipulator and a grip for the driving manipulator that can be easily moved to the back side of the hand.

[0007]

In view of the above-mentioned problems, the inventors of the present invention have conducted diligent research and found that the problem can be solved by providing an operation force transmission section for the driving operator on the back side of the hand. The invention was completed. That is, the present invention, which has solved the above-mentioned problems, provides a driving operator for a vehicle that performs a driving operation of a vehicle by gripping a grip provided in a substantially vertical direction in the vicinity of a driver's seat with a hand and operating in the left and right directions. An operating force transmission portion is also provided on the back side of the hand of the grip portion. In this driving operation element, the operating force of the driver is transmitted to the driving operation element by the grip portion. In this driving operation element, the operating force transmission section (in the embodiment described below) provided on the back side of the grip portion is used. The instep-side operation force transmission unit) transmits the operation force of the driver to the driving operator from the back side of the hand. This makes it easy for the driver to move the driver to the back of his / her hand.

Further, according to the present invention, which has solved the above-mentioned problems, a grip portion is provided in a substantially vertical direction on an upper portion of a driving operator provided near a driver's seat, and an operating force transmission portion is provided also on the back side of the hand. Is characterized by. According to the grip portion for the driving operator, the operating force transmitting portion (back side operating force transmitting portion in the embodiment described below) can transmit the operating force of the driver to the driving operator from the back side of the hand. It becomes easy to move the driver to the back side of the hand.

Is detected (output) as. With respect to the operation amount in this case as well, with respect to the neutral state of the joystick 1, the case of tilting to the right is the right steering operation amount, and the case of tilting to the left is the left steering operation amount. Then, the steering operation amount sensor 2 outputs the detected value to the control means 4. By the way, the operation of tilting the joystick 1 in the left-right direction is a steering operation of the vehicle.

The joystick 1 is arranged, for example, near the right side of the driver's seat so that the driver of the vehicle can operate it with his / her right hand. The joystick 1 is a pipe-shaped spindle 1.
B has a structure in which a grip portion 1A is provided on the upper part of the main shaft 1
The lower end of B is supported by a tilting support mechanism so as to be tiltable in the left-right direction and the front-back direction. The grip 1 is composed of a grip body 1Aa held by the palm of the driver and a back side operation force transmission unit 1Ab located on the back side of the hand.
The grip 1A will be described in detail later.

[Brake System] Next, the configuration of the brake system in the drive operation device E will be described. The brake system of this vehicle does not have a brake pedal unlike a normal vehicle.

Further, the brake system of this vehicle does not have a brake booster that utilizes negative pressure of the engine or a master cylinder. Instead, it has a pump for brake fluid pressure generation and a proportional solenoid valve for brake fluid pressure control, such as a traction control system (TCS) or anti-brake lock system (ABS), and the brake fluid pressure generated by the pump is Is applied to the wheel cylinder via a proportional solenoid valve. A brake fluid pressure sensor 12 is attached to the wheel cylinder so that the brake fluid pressure of the wheel cylinder is detected and transmitted to the control means 4. The brake actuator 7 corresponds to the proportional solenoid valve described above, and is driven based on the drive signal generated by the control means 4.

[Throttle System] Next, the configuration of the throttle system in the drive operation device E will be described. The throttle system of this vehicle does not have a throttle pedal (accelerator pedal) unlike a normal vehicle. Instead, the joystick 1 has a role of a throttle pedal, and as described above, when the operation of tilting the joystick 1 in the neutral state to the front is performed, the throttle valve is opened.

The throttle valve of this vehicle is driven by a valve drive motor, and the opening of the throttle valve is monitored by a throttle opening sensor 11.

[Gripping Part of First Embodiment] The gripping part of the first embodiment will be described with reference to FIGS. 1 and 2. FIG. 2 to be referred to is a perspective view showing a grip portion of the first embodiment,
(A) shows a state where the hand is not placed, and (b) shows a state where the hand is placed. In each of the embodiments described below, the grip portion is a main part of the joystick. Therefore, the description of the grip portion is replaced with the description of the joystick. As shown in FIGS. 1 and 2, the grip portion 1A of the first embodiment is provided above the main shaft 1B of the joystick 1. The grip portion main body 1Aa of the grip portion 1A is a portion that is gripped (gripped) by the driver, and the driver can grasp the grip portion main body 1Aa as shown in FIG.
As shown in (b), the operator operates the joystick 1 by holding it with the palm. In the present embodiment, the grip portion 1A is provided with a branch-shaped instep-side operation force transmission portion 1Ab that branches below the grip portion main body 1Aa and extends upward. As shown in FIG. 2 (a), the root side of the instep-side operation force transmitting portion 1Ab branched from the grip body 1Aa has a curved shape, but the branched portion may be bent at a right angle to form an angular state. Good.

A gap c between the grip portion main body 1Aa and the instep-side operation force transmitting portion 1Ab shown in FIG. 2A has a gap through which an open palm can be inserted. This is because if the gap c is narrow, it becomes impossible to grip the grip body 1Aa. Further, when the hand placed in the gap c is moved to another place, it may cause trouble. On the other hand, if the gap c is wide,
It is easy to grip the grip body 1Aa (see FIG. 2B), and it is easy to move the hand placed in the gap c to another place. However, it is not preferable that a large gap c (play interval [ineffective stroke]) still exists between the back of the hand and the back side operating force transmitting portion 1Ab when the grip portion main body 1Aa is gripped. If the instep side operation force transmission unit 1Ab and the back of the hand are not in contact with each other, the joystick 1 is operated from the instep side via the instep side operation force transmission unit 1Ab.
Because it cannot be transmitted to. In addition, the above-mentioned play gap generated between the back of the hand and the back side operation force transmitting portion 1Ab tends to become large when the operation of moving the joystick 1 to the palm side is performed (on the contrary, when the operation of moving the joystick 1 to the back side is performed, The intervals are getting smaller or disappearing).

Therefore, the clearance c is such that the ease of insertion of the palm, the ease of gripping the grip body 1Aa, the size of the palm, and the size of the play interval (ineffective stroke) vary depending on the operating direction of the joystick 1, etc. The shape (width of the gap c) and the like are set in consideration of the above.

By the way, the joystick 1 without holding the grip body 1Aa, that is, with the palm open.
It is often done to move the to the palm side. This is because it is easy for the driver because it is not necessary to grip the grip body 1Aa. In the same manner as above, when the palm is opened (without grasping the grip body 1Aa), only the back of the hand is brought into contact with the back side operation force transmitting portion 1Ab and the joystick 1 is moved to the back side of the hand (that For a driver who prefers to operate the joystick 1), the gap c may be wide.

The instep-side operation force transmitting portion 1Ab in the first embodiment is designed to have sufficient rigidity and durability to withstand the operation force. By the way, this grip 1
Since the upper part of the gap c of A is open, there is an advantage that the palm can be easily placed in the gap c and the placed palm can be easily moved to another place.

The operation of the driving operation device E having the grip portion 1A of the first embodiment will be described with reference to FIGS.

When the driver sits in the driver's seat, his / her hand is inserted into the gap c of the grip portion 1A of the joystick 1 and the grip portion main body 1 is inserted.
Hold Aa. Then, the driver performs a driving operation. When accelerating, the joystick 1 is tilted forward to perform a throttle operation. At this time, the joystick 1 is operated in a direction away from the center of the body, but since it is not the operation of moving the joystick 1 to the back side of the hand, the joystick 1 can be easily tilted forward. When the brake is applied, the joystick 1 is tilted backward to perform a braking operation. At this time, since the operation is directed toward the center of the body, the joystick 1 can be easily tilted backward (toward the driver). When turning to the left, the left steering operation is performed to tilt the joystick 1 to the left. At this time, since the operating force can be transmitted to the grip portion 1A (grip portion main body 1Aa) with the palm, the joystick can be easily tilted to the left side (palm side). In these operations, the instep-side operation force transmission portion 1Ab does not interfere.

On the other hand, when bending to the right, the gripping unit body 1
Since the operation force can be transmitted from the back of the hand to the back side operation force transmission portion 1Ab branched from Aa, the joystick can be easily tilted to the right side (back side of the hand). At this time, unlike the case where the grip body 1Aa is firmly gripped and the operation force is transmitted only to the grip body 1Aa, it is easy. If the instep-side operation force transmitting portion 1Ab is not provided, the operation force to the instep side of the hand cannot be transmitted to the joystick 1 unless the grip portion main body 1Aa is firmly gripped, which imposes a physical burden on the driver. Become. Of course, the operation is not easy. That is, according to the present invention, when the joystick 1 is operated on the back side of the hand, the operation force can be transmitted from the back side of the hand to the joystick 1, and it is not necessary to firmly grip the grip body 1Aa. Operation becomes easy.

For this reason, it is preferable that the instep-side operation force transmitting portion 6Ab be made of a material that is thick to some extent or that has a shape-retaining function.
By the way, the belt of the instep-side operation force transmission portion 6Ab may be divided into an upper belt and a lower belt, and both may be stopped by a buckle or Velcro (trademark).

The present invention described above is not limited to the above-described embodiments (first to sixth embodiments) of the present invention, and can be widely modified and implemented. For example, the first
The embodiment, the fifth embodiment, and the sixth embodiment may be provided with a clearance adjusting mechanism for adjusting the width of the clearance c as in the third embodiment and the fourth embodiment. Further, as the gap adjusting mechanism, various ones such as one using a pneumatic mechanism and one using a movable mechanism can be applied in addition to the length adjustment (buckle and velcro tape stop) of the folded portion of the belt of the sixth embodiment. Further, as shown in the first to sixth embodiments, the gap does not always have to be open.

Further, in the present invention, the mounting state (fixed state, mounted state, winding state, etc.) of the instep side operating force transmitting portion with respect to the grip body is not limited in any way, and the instep side operating force transmitting portion is not limited. May be removable from the grip body. Further, the grip portion (grip portion main body) may be removable from the main shaft of the joystick. That is, the mounting state (fixed state, mounted state, winding state ...) Of the grip portion main body (grasping portion) with respect to the main axis of the joystick is not limited in any way. In addition, the grip body (and / or the instep-side operation force transmission unit) may be rotatably attached to the main shaft of the joystick to handle a right-handed driver or a left-handed driver. Further, for example, when the vehicle is running at a high speed at a constant speed, if the throttle is operated on the back side of the hand, the tension generated when the same posture is continued for a long time may be released and the user may be able to relax. In such a case, the grip body (and / or the instep-side operation force transmitting portion) is 90 ° with respect to the main shaft.
It is good to be able to swing around. Further, for example, a mechanism may be provided in the grip body to restrict rotation and swing motion when the grip is gripped.

The present invention is also applicable to vehicles (general vehicles such as passenger cars, special vehicles such as construction machinery and military vehicles), aircraft,
It can also be applied to ships and the like. Further, in the embodiment of the invention described above, the joystick tilts, but it may slide and move in parallel.
