Accelerator 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

Technical Field

[0001] The present invention relates to an accelerator device for a vehicle and a vehicle equipped with the same, and particularly to an improvement in an anti-misoperation structure for reducing accidental misoperation between the accelerator and the brake.

Background Art

[0002] As a background art for preventing misoperation between the accelerator and the brake, for example, there is an "Automobile Accelerator Misoperation Prevention Device" described in Patent Document 1 below. This device pivotally attaches the base of the accelerator pedal lever to the accelerator arm, and when a certain downward impact force acts on the opposing parts of the accelerator arm and the accelerator pedal lever, a semi-fixed member that disengages is attached, and a stopper that locks the lowered position of the accelerator arm to a predetermined position is provided. A buffer member is disposed on the accelerator pedal lever or the floor surface. Therefore, when the accelerator pedal is operated normally, it can be depressed smoothly as in the past. However, when the accelerator pedal is mistaken for the brake and suddenly depressed, the movement of the accelerator pedal can be instantaneously stopped.

[0003] According to this, normally, as shown in FIG. 1 of the same publication, when the accelerator pedal is depressed slowly, the accelerator pedal lever and the accelerator arm are integrated by the adsorption of a permanent magnet, and thus a normal accelerator operation is performed. On the other hand, when the accelerator pedal is mistaken for the brake pedal and rapidly depressed, as shown in FIG. 3, the permanent magnet is separated by the impact, and only the accelerator pedal lever is depressed. When the foot is removed from the pedal lever, it returns to the original state by the spring.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the background technology described above, in the case of abnormal pressing where the accelerator pedal is lightly pressed and then suddenly pressed hard as if to apply the brakes, as shown in Figure 4 of the publication, the stopper contacts the floor surface and supports the accelerator arm in that position, while only the accelerator pedal lever is pushed further down, crushing the cushioning member, causing the permanent magnet to separate and stopping the pressing of the accelerator arm. In other words, only the pressing of the accelerator arm stops, and the accelerator does not return to its original position. Furthermore, even though the accelerator pedal has been mistaken for the brake pedal, there is no function to notify the driver of this, making it impossible to correct the pedal misapplication.

[0006] The present invention focuses on the above points, and its purpose is to provide an accelerator device that prevents abnormal acceleration of the vehicle even when the accelerator pedal is mistakenly pressed instead of the brake pedal, and that can also notify the driver of the occurrence of pedal misapplication. [Means for solving the problem]

[0007] The present invention is characterized in that a transmission / interruption mechanism is provided between the pedal mechanism and the accelerator mechanism, thereby interrupting the movement of the accelerator pedal relative to the accelerator lever when the accelerator pedal is abnormally pressed, and restoring the movement of the accelerator pedal to the accelerator lever when the abnormal pressing condition is resolved.

[0008] In the primary configuration, the blocking means uses the magnetic attraction force. Therefore, if the accelerator pedal is abnormally depressed, the magnetic attraction is released, and the movement of the accelerator pedal relative to the accelerator lever is interrupted. Furthermore, when the blocking means is activated, the accelerator mechanism returns the accelerator lever to the deceleration direction. When the abnormal depression is resolved, the lever returns to its original position due to a return spring.

[0009] In another embodiment, the accelerator pedal is positioned so as to extend in the direction of the accelerator lever during idling, and when the shut-off means is activated, the accelerator pedal is in an unusual position or posture, allowing the driver to recognize that the accelerator has been mistakenly pressed instead of the brake. The aforementioned and other purposes, features, and advantages of the present invention will become clear from the following detailed description and accompanying drawings. [Effects of the Invention]

[0010] According to the present invention, when the accelerator pedal is mistakenly pressed abnormally instead of the brake pedal, the accelerator pedal and accelerator lever are disconnected, thereby preventing abnormal acceleration of the vehicle and alerting the driver to the mistake through the impact or other sensation when the pedals are disconnected. [Brief explanation of the drawing]

[0012] The best mode for carrying out the present invention will be described in detail below based on examples. [Examples]

[0013] First, Embodiment 1 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 (A) showing the idling state and Figure (B) showing the abnormally depressed state of the accelerator pedal. In these figures, the accelerator device 10 is configured such that an accelerator pedal depression transmission / blocking mechanism (hereinafter simply referred to as the "transmission / blocking mechanism") 200 is provided between the accelerator mechanism 100 and the pedal mechanism 300. The transmission / blocking mechanism 200 is composed of a fixed part 210 and a movable part 220, with the fixed part 210 provided on the accelerator mechanism 100 side and the movable part 220 provided on the pedal mechanism 300 side.

[0014] Of these, the accelerator mechanism 100 (genuine throttle) is installed in ordinary passenger cars, and various types are available. For example, it has a function that detects the speed and stroke of accelerator pedal operation using sensors and converts it 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 end of the accelerator lever 102 of the accelerator mechanism 100, and when the pedal mechanism 300 is not pressed, the accelerator mechanism 100 is biased to return to the idling state.

[0015] In contrast, in this embodiment, a transmission / disconnection mechanism 200 is provided instead of the pedal mechanism 300. More specifically, the accelerator lever 102 of the accelerator mechanism 100 is provided with a mounting bracket 212 for the fixing part 210 of the transmission / disconnection mechanism 200. 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, sandwiching 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 arrow FA, and a magnet 216 is provided on this front plate 214. As the magnet 216, for example, neodymium, which has strong magnetic force or attractive force, is used.

[0016] On the other hand, the mounting bracket 212 extends downward, and a movable part 220 is provided on this extended portion 218. The movable part 220 is centered around a movable piece 222. When viewed from the side direction indicated by the arrow FB, the movable piece 222 has a roughly crank shape and is pivotally supported on the extended portion 218 so as to be rotatable about a pivot axis 224. A magnetic opposing surface 226 extends from the upper side of this movable piece 222 so as to face the magnet 216. This magnetic opposing surface 226 is made of a material that magnetically bonds to the magnet 216 of the fixed part 210. In addition, one end of a return spring 230 is fixed to the upper tip of the movable piece 222, and the other end of this return spring 230 is fixed to an L-shaped fixing plate 232. The fixing plate 232, together with the accelerator mechanism 100 described above, is fixed to the chassis or housing side of the automobile by bolt and nut means 234.

[0017] On the other hand, a pedal lever 302 of the pedal mechanism 300 is provided on the lower side of 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 axis 224, and the magnetic opposing surface 226 also rotates against the spring force of the return spring 230. Then, when the driver releases their foot from the accelerator pedal 304, the return spring 230 compresses, 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 the accelerator pedal 304 of the pedal mechanism 300 are in the extension direction of the accelerator lever 102 of the accelerator mechanism 100. That is, the position of the accelerator pedal 304 is almost the same as the state where the transmission / cutoff mechanism 200 of this embodiment is not attached, and the driver can step on the accelerator pedal 304 without discomfort.

[0019] Next, referring also to FIG. 2, the operation of this embodiment will be described. First, in the idling state where the driver is not stepping on the accelerator pedal 304, as shown in FIG. (A) of the same figure, the magnet 216 of the fixed portion 210 of the transmission / cutoff mechanism 200 and the magnetic facing surface 226 of the movable portion 220 are in a coupled state. Further, the return spring 230 is in a contracted state, and the accelerator lever 102 of the accelerator mechanism 100 is in the idling position.

[0020] From this idling state, as shown by the arrow FC in FIG. (B) of the same figure, when the driver steps on the accelerator pedal 304, the movable portion 220 of the transmission / cutoff mechanism 200 rotates in the direction of the arrow FD about the rotation shaft 224. Since the magnet 216 of the fixed portion 210 is coupled to the magnetic facing surface 226 of the movable portion 220, the fixed portion 210 also rotates in the direction of the arrow FD. As a result, the return spring 230 extends and the accelerator lever 102 shifts in the direction of the arrow FE. Then, the throttle (not shown) is opened by the accelerator mechanism 100, fuel is supplied to the engine, the rotation of the engine increases, and the automobile starts to run. If the accelerator pedal 304 is further depressed, the speed increases, and if the accelerator pedal 304 is released, the speed decreases. In this way, the automobile runs.

[0021] In this driving condition, if the driver mistakenly presses the accelerator instead of the brake and forcefully depresses the accelerator pedal 304 instead of the brake, the fixed part 210 and the movable part 220 of the transmission / disconnection mechanism 200 will separate, as indicated by the arrow FF in Figure (C). That is, the connection between the magnet 216 of the fixed part 210 and the magnetic opposing surface 226 of the movable part 220 is broken, and the two separate. As a result, the transmission of the movement of the accelerator pedal 304 to the accelerator lever 102 is interrupted, and the accelerator lever 102 returns to the idling position due to the action of the accelerator mechanism 100, as indicated by the arrow FH. At the same time, the fixed part 210 of the transmission / disconnection mechanism 200 also returns to the idling position, as indicated by the arrow FI (see Figure (A)).

[0022] In other words, when the accelerator pedal 304 is abnormally pressed, the transmission / blocking mechanism 200 blocks the transmission of movement to the accelerator lever 102, and the engine goes into an idle state. Also, when the coupling by the magnet 216 is released, the shock is transmitted to the driver from the foot pressing the accelerator pedal 304. The sound of release that occurs at the time of the shock is also transmitted to the driver's ears. In addition, the accelerator pedal 304 becomes almost vertical or in a position deep inside the footwell under the driver's seat, and the driver's foot is in an unusual position. That is, the driver's foot is bent sharply at the ankle. From the shock, sound, and the position of the foot associated with the release of the magnet, the driver realizes that they have mistakenly pressed the accelerator instead of the brake.

[0023] When the driver releases their foot from the accelerator pedal 304, the return spring 230 causes the accelerator pedal 304 to return to the idling position, and the magnetic opposing surface 226 of the movable part 220 and the magnet 216 of the fixed part 210 reconnect, returning to the idling state shown in Figure 2(A). Then, if the driver presses the brake (not shown), the car stops. If the driver presses the accelerator pedal 304 again, the car accelerates again.

[0024] As described above, the following effects can be obtained according to this embodiment. a. When the accelerator pedal is pressed abnormally by mistake instead of the brake, releasing the accelerator causes the accelerator to return to the deceleration direction and even to the idling state. As a result, engine braking is applied, and the vehicle decelerates. b. When the accelerator pedal is pressed too hard, the driver can recognize that they have mistakenly pressed the brake instead of the accelerator based on the impact or sound of the magnet separating and the angle of their foot. c) It can utilize the existing accelerator mechanism and can be retrofitted to passenger cars. [Examples]

[0025] Next, with reference to Figure 3, Embodiment 2 of the present invention will be described. The same reference numerals or the letter A will be used for elements corresponding to those in the embodiments described above. In this embodiment, as shown in Figure (A), a transmission / shutdown mechanism 200A is provided on the accelerator lever 102 of the accelerator mechanism 100. The transmission / shutdown mechanism 200A consists of a fixed part 210A and a movable part 220A. The fixed part 210A and the movable part 220A are supported by a rotating part 250A, with the movable part 220A rotatably supported on the fixed part 210A around a pivot axis 224A. The pedal lever 302A of the pedal mechanism 300A is attached to the movable part 220A side of the rotating part 250A. In this embodiment, the pedal lever 302A is bent relative to the accelerator pedal 304A, thereby enabling attachment to the rotating part 250A of the transmission / shutdown 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 side, but in this embodiment, as shown in Figure (C), it is attached to the fixed part 210A side. The return spring 230A is provided between the fixed part 210A and the movable part 220A.

[0027] Next, the operation of this embodiment will be explained. In the idling state, when the driver is not pressing the accelerator pedal 304A, the fixed part 210A and the movable part 220A of the transmission / disconnection mechanism 200A are coupled together, as shown in Figure (A). From this idling state, when the driver presses the accelerator pedal 304A, as indicated by the arrow FC in Figure (B), the transmission / disconnection mechanism 200A as a whole rotates in the direction of the arrow FE. As a result, the accelerator lever 102 also shifts in the direction of the arrow FE. Therefore, the accelerator mechanism 100 opens the throttle (not shown), fuel is supplied to the engine, the engine speed increases, and the automobile begins to move. Pressing the accelerator pedal 304A further increases the speed, and releasing the accelerator pedal 304A decreases the speed. In this way, the automobile moves.

[0028] In this driving condition, if the driver mistakenly presses the accelerator instead of the brake and forcefully depresses the accelerator pedal 304A instead of the brake, the fixed part 210A and the movable part 220A of the transmission / disconnection mechanism 200A will separate, as shown in Figure (C). That is, as indicated by the arrow FF, when the accelerator pedal 304 is pressed, the connection between the movable part 220A and the fixed part 210A by the magnet 216A is released, the return spring 230A extends, and the movable part 220A rotates relative to the fixed part 210A. As a result, even if the accelerator pedal 304A is pressed, the transmission of the movement of the accelerator pedal 304A to the accelerator lever 102 is interrupted, and as indicated by the arrow FH, the accelerator lever 102 returns to the deceleration direction due to the action of the accelerator mechanism 100, and further returns to the idling state.

[0029] In addition, as in the above embodiment, the detachment of the magnet 216A produces an impact and sound, and the accelerator pedal 304A becomes almost vertical, so the driver realizes that they have mistakenly pressed the accelerator instead of the brake. When the driver releases their foot from the accelerator pedal 304A, as shown in Figure (D), the fixed part 210A and the movable part 220A of the transmission / disconnection mechanism 200A are coupled by the action of the return spring 230A. As a result, the driver is able to perform normal accelerator operation again.

[0030] As described above, according to this embodiment, even if the accelerator pedal is mistakenly pressed instead of the brake pedal, abnormal acceleration is prevented, and the driver can be aware that they have mistakenly pressed the brake pedal instead. Furthermore, the existing accelerator mechanism can be used as is, and it can be retrofitted to passenger cars. [Examples]

[0031] Next, with reference to Figure 4, Embodiment 3 of the present invention will be described. The same reference numerals or the letter B will be used for elements corresponding to those in the embodiments described above. This embodiment differs from the embodiment in Figure 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 in Embodiment 2. [Examples]

[0032] Next, with reference to Figures 5 and 6, Embodiment 4 of the present invention will be described. The embodiments described above are for suspended accelerators, but this embodiment is an example of an organ-type accelerator with pedals 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 / blocking mechanism 600 is provided between the accelerator mechanism 500 and the pedal mechanism 700.

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

[0034] Next, the transmission / blocking mechanism 600 is centered around a movable piece 610. The movable piece 610 is provided parallel to the accelerator pedal 710 of the pedal mechanism 700, and its lower end has a bent portion 612 that curves toward the lever pedal 506 of the accelerator mechanism 500. The lower end on the bent portion 612 side is in contact with the lever pedal 506 of the accelerator mechanism 500. An arm 614 extends from the upper end of the movable piece 610.

[0035] On the other hand, the pedal mechanism 700 is centered around the accelerator pedal 710, the lower end of which is in contact with the floor surface 502. In addition, triangular restricting plates 712 are provided on both sides of the lower end of the accelerator pedal 710 to restrict its downward movement. An arm 714 extends from the upper end of the accelerator pedal 710. A return spring 730 is provided between this arm 714 and the arm 614 on the movable piece 610 side of the transmission / blocking mechanism 600 described above. Furthermore, a magnet 720 is provided on the back surface of the upper pedal 710, on the side facing the movable piece 610, and a magnetic opposing surface 620 is provided on the side facing the movable piece 610.

[0036] Next, the operation of this embodiment will be described. In the idling state when the driver is not pressing 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, 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 / blocking mechanism 600.

[0037] From this idling state, as shown by the arrow FP in Figures 5(B) and 6(B), when the driver presses down the accelerator pedal 710, the lower end of the movable piece 610 of the transmission / cutoff mechanism 600 pushes the lever pedal 506 of the accelerator mechanism 500. The accelerator mechanism 500 opens the throttle (not shown), fuel is supplied to the engine, the engine speed increases, and the car starts moving. Pressing the accelerator pedal 710 further increases the speed, and releasing the accelerator pedal 710 decreases the speed.

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

[0039] In other words, if the accelerator pedal 710 is pressed too hard, the transmission / blocking mechanism 600 blocks the transmission of movement to the accelerator lever 504, and the engine goes into idle mode. Also, when the coupling by the magnet 720 is released, the shock is transmitted from the foot pressing the accelerator pedal 710 to the driver. The sound of the release that occurs during the shock is also transmitted to the driver's ears. From these shocks and sounds associated with the release of the magnet, the driver realizes that they have mistakenly pressed the accelerator instead of the brake.

[0040] When the driver releases their foot from the accelerator pedal 710, the return spring 730 causes the movable piece 610 to return to its idling position, and the magnetic opposing surface 620 of the movable piece 610 and the magnet 720 reconnect, returning to the idling state shown in Figures 5(A) and 6(A). Then, when the driver presses the brake (not shown), the vehicle stops. Also, when the driver presses the accelerator pedal 710, the vehicle accelerates again. This embodiment also provides the same technical effects as the previous embodiment.

[0041] <Other Embodiments> The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention. For example, the following are also included. (1) The shapes and dimensions of the parts shown in the above embodiment are examples only and can be modified to produce similar functions. (2) The strength of the magnetic attraction force shown in the above embodiment should be set appropriately according to the degree to which the accelerator pedal depression is judged to be abnormal. Alternatively, it may be set individually for each driver. (3) Although the present invention is primarily intended for automobiles, it is applicable to all vehicles that use an accelerator pedal for acceleration and deceleration. [Industrial applicability]

[0042] According to the present invention, when the accelerator pedal is abnormally pressed by mistake instead of the brake pedal, the accelerator pedal and accelerator lever are disconnected. This prevents the vehicle from accelerating, and the driver can recognize the mistake due to the impact of the disconnection, making it suitable as a vehicle accelerator device that reduces accidents caused by mistakenly pressing the accelerator instead of the brake.
