Acceleration device and vehicle

Abstract

[Problem] To provide an acceleration device which, even in the event of abnormally depressing an accelerator pedal erroneously instead of a brake pedal, is capable of preventing abnormal acceleration of a vehicle and also of informing the driver that erroneous pedal depression has occurred. [Solution] When the driver has erroneously stepped strongly on the accelerator pedal 304 instead of the brake, the engagement between a magnet 216 of a fixation part 210 and a magnetic opposing surface 226 of a movable part 220 in a transmission / interruption mechanism 200 are released, and are separated from each other. Accordingly, the motion of the accelerator pedal 304 with respect to an accelerator lever 102 is blocked, and by the action of an accelerator mechanism 100, the accelerator lever 102 returns to a state at idling. At the same time, shocks and sounds generated by the magnet 216 at disengagement are transmitted to the driver, so that the position of the foot of the driver is made different from the normal position. Accordingly, the driver can be aware of erroneous depression of the accelerator pedal instead of the brake pedal.

Description

Accelerator device and vehicle

[0001] The present invention relates to a vehicle accelerator device and a vehicle equipped with the same, and more particularly to an improvement in an erroneous operation prevention structure that reduces accidents caused by mistaking the accelerator for the brake.

[0002] An example of background technology for preventing the confusion of pressing the accelerator instead of the brake is the "Automobile Accelerator Misoperation Prevention Device" described in Patent Document 1 below. This device pivots the base of the accelerator pedal lever to the accelerator arm, attaches a semi-fixed member that separates when a certain downward impact force acts on the opposing part of the accelerator arm and accelerator pedal lever, is equipped with a stopper that locks the accelerator arm in a predetermined lowered position, and has a buffer member disposed on the accelerator pedal lever or floor surface, so that when the accelerator pedal is operated normally, it can be pressed down smoothly as before, but if the accelerator pedal is accidentally pressed down by mistake for the brake, the movement of the accelerator pedal can be stopped instantly.

[0003] According to this, when the accelerator pedal is normally depressed slowly, as shown in Figure 1 of the publication, the accelerator pedal lever and accelerator arm are attracted to each other by the permanent magnet, and normal accelerator operation is performed. However, if the accelerator pedal is mistaken for the brake pedal and depressed quickly, the permanent magnet separates due to the impact, as shown in Figure 3, and only the accelerator pedal lever is depressed. When the foot is released from the pedal lever, the spring returns it to its original state.

[0004] Japanese Unexamined Patent Publication No. 6-156111

[0005] However, in the above-mentioned background art, if the driver lightly depresses the accelerator pedal and then depresses it hard with the intention of braking suddenly, as shown in Figure 4 of the publication, the stopper abuts against the floor and holds the accelerator arm in place, but only the accelerator pedal lever is pushed further downward, crushing the buffer material, separating the permanent magnets and stopping the accelerator arm from being depressed. In other words, only the accelerator arm stops being depressed, but the accelerator does not return to its original position. Furthermore, there is no function to notify the driver that the accelerator pedal is mistaken for the brake pedal, so the driver cannot correct the mistake.

[0006] The present invention has been made in view of the above points, and its object is to provide an accelerator device that can prevent abnormal acceleration of a vehicle even when the accelerator pedal is mistakenly depressed instead of the brake pedal, and can notify the driver that a mistake has occurred.

[0007] The present invention is characterized in that a transmission / shutoff mechanism is provided between the pedal mechanism and the accelerator mechanism, which shuts off the movement of the accelerator pedal relative to the accelerator lever when the accelerator pedal is abnormally depressed, and returns to normal when the abnormal depression state is resolved, transmitting the movement of the accelerator pedal to the accelerator lever.

[0008] According to a main aspect, the blocking means uses the magnetic attraction. Therefore, if the accelerator pedal is abnormally depressed, the magnetic attraction is released, blocking the movement of the accelerator pedal relative to the accelerator lever. When the blocking means is activated, the accelerator lever is returned in the deceleration direction by the accelerator mechanism. When the abnormal depression is resolved, the return spring restores the accelerator.

[0009] According to another aspect, the accelerator pedal is provided so as to be in the extension direction of the accelerator lever when the vehicle is idling, and when the accelerator pedal is in an unusual state or position in a state in which the cut-off means has cut off the accelerator, the driver can be notified that the accelerator has been mistaken for the brake. The above and other objects, features, and advantages of the present invention will become apparent from the following detailed description and the accompanying drawings.

[0010] According to the present invention, when the accelerator pedal is mistakenly depressed for the brake, the accelerator pedal and the accelerator lever are disconnected, thereby preventing abnormal acceleration of the vehicle and informing the driver of the mistaken depression by the impact or the like at the time of disconnection.

[0012] The best mode for carrying out the present invention will be described in detail below with reference to examples.

[0013] First, a first embodiment of the present invention will be described with reference to Figures 1 and 2. Figure 1 shows the entire accelerator device of this embodiment, with Figure 1(A) showing the vehicle in an idling state and Figure 1(B) showing the vehicle in an abnormal accelerator pedal depression state. In these figures, the accelerator device 10 includes an accelerator depression transmission / shutoff mechanism (hereinafter simply referred to as the "transmission / shutoff mechanism") 200 disposed between an accelerator mechanism 100 and a pedal mechanism 300. The transmission / shutoff mechanism 200 is comprised of a fixed portion 210 and a movable portion 220, with the fixed portion 210 being disposed on the accelerator mechanism 100 side and the movable portion 220 being disposed on the pedal mechanism 300 side.

[0014] Of these, the accelerator mechanism 100 (genuine throttle) is installed in ordinary passenger cars and is available in a variety of versions. For example, it has a function of detecting the accelerator pedal depression speed and stroke with a sensor and converting them into an electrical signal, and the opening and closing of the electronic throttle is controlled based on this signal. Normally, a pedal mechanism 300 is attached to the tip of the accelerator lever 102 of the accelerator mechanism 100, and when the pedal mechanism 300 is not depressed, the accelerator mechanism 100 urges the engine to return to an idling state.

[0015] In contrast, in this embodiment, a transmission / disconnection mechanism 200 is provided instead of the pedal mechanism 300. More specifically, a mounting bracket 212 for a fixed portion 210 of the transmission / disconnection mechanism 200 is provided on the accelerator lever 102 of the accelerator mechanism 100. The shape and structure of this mounting bracket 212 correspond to the shape of the accelerator lever 102, and in the illustrated example, it is U-shaped so as to sandwich the accelerator lever 102 from the outside. A front plate 214 is provided on the front side of this mounting bracket 212 as viewed from the arrow FA, and a magnet 216 is provided on this front plate 214. The magnet 216 is made of neodymium, which has a strong magnetic or attractive force, for example.

[0016] Meanwhile, the mounting bracket 212 extends downward, and a movable part 220 is provided relative to this extension 218. The movable part 220 is configured around a movable piece 222. When viewed from the side indicated by arrow FB, the movable piece 222 is generally crank-shaped and is rotatably supported by the extension 218 around a rotation shaft 224. A magnetic opposing surface 226 extends from the upper side of the movable piece 222 so as to face the magnet 216. This magnetic opposing surface 226 is made of a material that magnetically couples with the magnet 216 of the fixed part 210. One end of a return spring 230 is fixed to the tip of the upper side of the movable piece 222, and the other end of the return spring 230 is fixed to an L-shaped fixed plate 232. The fixed plate 232, together with the accelerator mechanism 100 described above, is fixed to the chassis or housing of the automobile by bolt and nut means 234.

[0017] Meanwhile, a pedal lever 302 of the pedal mechanism 300 is provided below the movable piece 222, and an accelerator pedal 304 is provided at the tip of the pedal lever 302. That is, when the driver presses down on the accelerator pedal 304, the movable piece 222 rotates around the movable shaft 224, and the magnetic opposing surface 226 also rotates against the spring force of the return spring 230. When the driver relaxes or releases the accelerator pedal 304, the return spring 230 contracts, causing the movable piece 222 to rotate in the opposite direction, and the accelerator pedal 304 returns to its original position.

[0018] The pedal lever 302 and accelerator pedal 304 of the pedal mechanism 300 are arranged in the extension direction of the accelerator lever 102 of the accelerator mechanism 100. In other words, the position of the accelerator pedal 304 is substantially the same as when the transmission / disconnection mechanism 200 of this embodiment is not installed, allowing the driver to depress the accelerator pedal 304 without any discomfort.

[0019] Next, the operation of this embodiment will be described with reference to Figure 2. First, when the vehicle is idling and the driver is not depressing the accelerator pedal 304, as shown in Figure 2(A), the magnet 216 of the fixed part 210 of the transmission / disconnection mechanism 200 and the magnetic facing surface 226 of the movable part 220 are in a coupled state. Also, the return spring 230 is in a compressed state, and the accelerator lever 102 of the accelerator mechanism 100 is in the idling position.

[0020] From this idling state, as shown by arrow FC in FIG. 1B, when the driver depresses the accelerator pedal 304, the movable part 220 of the transmission / disconnection mechanism 200 rotates in the direction of arrow FD around the pivot shaft 224. Because the magnet 216 of the fixed part 210 is coupled to the magnetically opposed surface 226 of the movable part 220, the fixed part 210 also rotates in the direction of arrow FD. This causes the return spring 230 to expand, and the accelerator lever 102 to shift in the direction of arrow FE. The accelerator mechanism 100 then opens the throttle (not shown), supplying fuel to the engine, increasing engine speed and allowing the vehicle to move. Further depressing the accelerator pedal 304 increases the vehicle's speed, and releasing the accelerator pedal 304 decreases the vehicle's speed. In this manner, the vehicle moves.

[0021] If, under these driving conditions, the driver accidentally depresses the accelerator pedal instead of the brake, mistaking accelerator pedal 304 for the brake and pressing down hard, fixed part 210 and movable part 220 of transmission / disconnection mechanism 200 will separate, as shown by arrow FF in Figure 1C. That is, magnet 216 of fixed part 210 and magnetic opposing surface 226 of movable part 220 will be disengaged, causing the two to separate. This will interrupt the transmission of the movement of accelerator pedal 304 to accelerator lever 102, and as shown by arrow FH, accelerator lever 102 will return to an idling state due to the action of accelerator mechanism 100. At the same time, fixed part 210 of transmission / disconnection mechanism 200 will also return to the idling position, as shown by arrow FI (see Figure 1A).

[0022] That is, when the accelerator pedal 304 is abnormally depressed, the transmission / disconnection mechanism 200 blocks the transmission of movement to the accelerator lever 102, and the engine enters an idling state. Furthermore, when the connection by the magnet 216 is released, the resulting impact is transmitted to the driver through the driver's foot pressing the accelerator pedal 304. The sound of the release generated upon impact is also transmitted to the driver's ears. Additionally, the accelerator pedal 304 assumes a nearly vertical position or posture deep in the footwell below the driver's seat, causing the driver's feet to bend differently than normal. In other words, the driver's feet are bent significantly from the ankles. The shock, sound, and foot position associated with the magnet release make the driver realize that they have mistakenly pressed the accelerator for the brake.

[0023] When the driver releases the accelerator pedal 304, the return spring 230 returns the accelerator pedal 304 to the idling position, and the magnetic opposing surface 226 of the movable part 220 and the magnet 216 of the fixed part 210 are coupled together to return to the idling position shown in FIG. 2A. Then, when the driver applies the brake (not shown), the car stops. When the driver applies the accelerator pedal 304 again, the car accelerates again.

[0024] As described above, this embodiment provides the following advantages: a) When the accelerator pedal is accidentally depressed instead of the brake, the accelerator is released, causing the accelerator to return to deceleration and even idling. This puts the engine brake into effect, slowing the vehicle. b) When the accelerator pedal is accidentally depressed, the driver can tell from the impact or sound of the magnets separating and the angle of the foot that they have mistaken the accelerator for the brake. c) The existing accelerator mechanism can be used as is, and this can be retrofitted to passenger cars.

[0025] Next, a second embodiment of the present invention will be described with reference to FIG. 3 . Elements corresponding to those in the above-described embodiment will be designated by the same reference numerals or the letter A. In this embodiment, as shown in FIG. 3A, a transmission / disconnection mechanism 200A is provided on the accelerator lever 102 of the accelerator mechanism 100. The transmission / disconnection mechanism 200A is composed of a fixed portion 210A and a movable portion 220A. The fixed portion 210A and the movable portion 220A are supported by a rotating portion 250A, with the movable portion 220A rotatably supported on the fixed portion 210A around a rotating shaft 224A. A pedal lever 302A of a pedal mechanism 300A is attached to the movable portion 220A side of the rotating portion 250A. In this embodiment, the pedal lever 302A is bent relative to the accelerator pedal 304A, allowing it to be attached to the rotating portion 250A of the transmission / disconnection mechanism 200A.

[0026] A magnet 216A is provided on the contact surface between the fixed part 210A and the movable part 220A. It may be provided on either surface, but in this embodiment, it is attached to the fixed part 210A side as shown in Fig. 1C. In addition, a return spring 230A is provided between the fixed part 210A and the movable part 220A.

[0027] Next, the operation of this embodiment will be described. When the vehicle is idling and the driver is not depressing the accelerator pedal 304A, the fixed portion 210A and the movable portion 220A of the transmission / disconnection mechanism 200A are coupled, as shown in FIG. 1A. From this idling state, when the driver depresses the accelerator pedal 304A, as shown by arrow FC in FIG. 1B, the entire transmission / disconnection mechanism 200A rotates in the direction of arrow FE. This causes the accelerator lever 102 to also shift in the direction of arrow FE. This causes the accelerator mechanism 100 to open the throttle (not shown), supplying fuel to the engine, increasing engine speed and allowing the vehicle to move. Further depressing the accelerator pedal 304A increases the vehicle's speed, and releasing the accelerator pedal 304A decreases the vehicle's speed. In this manner, the vehicle moves.

[0028] If, under these driving conditions, the driver accidentally depresses the accelerator instead of the brake, mistaking accelerator pedal 304A for the brake and pressing it hard, as shown in Figure 1C, fixed part 210A and movable part 220A of transmission / disconnection mechanism 200A will separate. That is, when accelerator pedal 304 is depressed as indicated by arrow FF, magnet 216A disengages movable part 220A from fixed part 210A, and return spring 230A expands, causing movable part 220A to rotate relative to fixed part 210A. As a result, even if accelerator pedal 304A is depressed, the transmission of the movement of accelerator pedal 304A to accelerator lever 102 is interrupted, and accelerator lever 102 returns to the deceleration direction due to the action of accelerator mechanism 100 as indicated by arrow FH, eventually returning to an idling state.

[0029] In addition, as in the previous embodiment, the driver realizes that he has mistakenly pressed the accelerator pedal for the brake pedal, as the magnet 216A is released, causing an impact and noise, and the accelerator pedal 304A becomes almost vertical. When the driver then releases his foot from the accelerator pedal 304A, the fixed part 210A and the movable part 220A of the transmission / disconnection mechanism 200A are connected by the action of the return spring 230A, as shown in Figure 1(D). This allows the driver to resume normal accelerator operation.

[0030] As described above, according to this embodiment, even if the driver accidentally steps on the accelerator pedal instead of the brake pedal, abnormal acceleration is prevented and the driver is informed that the pedal has been mistaken for the brake pedal. Furthermore, the existing accelerator mechanism can be used as is, and the system can be retrofitted to passenger cars.

[0031] Next, a third embodiment of the present invention will be described with reference to FIG. 4. Elements corresponding to those in the above-described embodiments will be designated by the same reference numerals or the letter B. This embodiment differs from the embodiment in FIG. 3 in that a return spring 230B is provided between the accelerator mechanism 100 and the movable part 220A. The basic operation is the same as that of the second embodiment.

[0032] Next, a fourth embodiment of the present invention will be described with reference to Figures 5 and 6. While the above-described embodiments are based on a suspended accelerator, this embodiment is based on an organ-type accelerator with pedals located on the floor. Figure 5 shows a perspective view, and Figure 6 shows a side view. In these figures, the accelerator device 12 is configured such that a transmission / disconnection mechanism 600 is provided between an accelerator mechanism 500 and a pedal mechanism 700.

[0033] Of these, accelerator mechanism 500 has the structure of an existing organ-type accelerator, and is equipped with an accelerator lever 504 protruding from floor surface 502 of the automobile, and a lever pedal 506 that operates this accelerator lever 504. When accelerator lever 504 is pressed with lever pedal 506, the throttle opens, and when released, a spring mechanism (not shown) returns lever pedal 506, closing the throttle. These points are the same as known organ-type accelerator mechanisms.

[0034] Next, transmission / disconnection mechanism 600 is configured mainly with movable piece 610. Movable piece 610 is provided parallel to accelerator pedal 710 of pedal mechanism 700, and has a bent portion 612 bent at its lower end toward lever pedal 506 of accelerator mechanism 500. The lower end of bent portion 612 abuts against lever pedal 506 of accelerator mechanism 500. An arm 614 extends from the upper end of movable piece 610.

[0035] Meanwhile, pedal mechanism 700 is centered around accelerator pedal 710, the lower end of which abuts against floor surface 502. Triangular restricting plates 712 are provided on both sides of the lower end of accelerator pedal 710 to restrict its downward movement. An arm 714 extends from the upper end of accelerator pedal 710. A return spring 730 is provided between this arm 714 and the arm 614 on the movable piece 610 side of transmission / shutoff mechanism 600. Furthermore, a magnet 720 is provided on the rear surface of upper pedal 710 facing the movable piece 610, and a magnetic opposing surface 620 is provided on one side of the movable piece 610.

[0036] Next, the operation of this embodiment will be explained. When the engine is idling and the driver is not depressing the accelerator pedal 710, as shown in Figures 5(A) and 6(A), the magnetic opposing surface 620 of the movable piece 610 and the magnet 720 of the accelerator pedal 710 are coupled together, and the return spring 730 is also compressed, so that the movement of the accelerator pedal 710 is transmitted to the lever pedal 506 via the transmission / shutoff mechanism 600.

[0037] 5(B) and 6(B), when the driver depresses accelerator pedal 710, the lower end of movable piece 610 of transmission / shutoff mechanism 600 presses lever pedal 506 of accelerator mechanism 500, which opens the throttle (not shown), supplies fuel to the engine, increases engine speed, and the automobile begins to move. Further depressing accelerator pedal 710 increases the speed, and releasing accelerator pedal 710 decreases the speed.

[0038] In this driving state, if the driver mistakenly steps on the accelerator instead of the brake and steps hard on accelerator pedal 710, mistaking it for the brake, the magnet 720 on the accelerator pedal 710 side and the magnetic opposing surface 620 on the movable piece 610 side will separate, as shown by arrows FQ in Figures 5(C) and 6(C), cutting off the transmission of the movement of accelerator pedal 710 to accelerator lever 504, and the accelerator lever 504 will return to the idling state due to the action of accelerator mechanism 500, as shown by arrow FR.

[0039] That is, when accelerator pedal 710 is depressed abnormally, transmission of movement to accelerator lever 504 is interrupted by transmission / interruption mechanism 600, and the engine enters an idling state. When the connection by magnet 720 is released, the resulting impact is transmitted to the driver through the foot pressing accelerator pedal 710. The release sound generated at the time of the impact is also heard by the driver. The impact and sound accompanying the release of the magnet make the driver realize that they have mistakenly pressed the accelerator for the brake.

[0040] When the driver releases the accelerator pedal 710, the return spring 730 returns the movable piece 610 to the idling position, and the magnetic opposing surface 620 of the movable piece 610 and the magnet 720 are coupled together to return to the idling position shown in FIGS. 5A and 6A. Then, when the driver applies the brake (not shown), the car stops. And when the driver applies the accelerator pedal 710, the car accelerates again. This embodiment can also achieve the same technical effects as the previous embodiment.

[0041] <Other Embodiments> The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention. For example, the following are included: (1) The shapes and dimensions of the components shown in the above embodiments are merely examples, and modifications can be made to achieve the same effect. (2) The strength of the magnetic attraction force shown in the above embodiments is set appropriately depending on the degree of accelerator pedal depression that is determined to be abnormal. It may also be set for each driver. (3) Although the present invention is primarily applicable to automobiles, it is applicable to all vehicles that accelerate and decelerate using an accelerator pedal.

[0042] According to the present invention, when the accelerator pedal is accidentally depressed by mistake for the brake, the accelerator pedal and accelerator lever are disconnected, which prevents the vehicle from accelerating and also lets the driver know that they have mistakenly depressed the accelerator pedal by the impact or the like that occurs when the pedal is disconnected. This is suitable as an accelerator device for a vehicle that reduces accidents caused by mistaking the accelerator for the brake.
