The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.
FIG. 1 is a schematic diagram illustrating an automobile accelerator pedal device (first embodiment) according to the present invention.
The accelerator pedal device (first embodiment) 11 is employed in the automobile 12, and when the driver M operates the pedal mechanism 13, the vehicle speed V of the automobile 12 is increased or decreased. The details will be described later.

  The automobile 12 is an MR (mid engine, rear drive) vehicle in which a wheel drive device (engine) 21 is disposed later, and includes an accelerator pedal device 11, an engine 21 connected to the accelerator pedal device 11, a vehicle body 22, and a front wheel 23. A rear wheel 24, a driver seat 25, a driver seat 26, and a wheel brake device 27 for braking the front wheel 23 and the rear wheel 24.

  The wheel brake device 27 is, for example, a hydraulic brake, a hydraulic pressure increasing mechanism 31 connected to the accelerator pedal device 11, and a caliper 32 (front wheel 23) connected to the hydraulic pressure increasing mechanism 31 and disposed on the front wheel 23 and the rear wheel 24. Only).

  The engine 21 is, for example, an existing gasoline engine, which is an inline 4-cylinder, 1500 CC, including a transmission (for example, 4-speed AT), a vehicle speed increasing / decreasing member 36, and an air cleaner 37 connected to the vehicle speed increasing / decreasing member 36. And a gasoline tank 38.

The vehicle speed increasing / decreasing member 36 is a carburetor 41 connected to the intake pipe, and specifically includes a throttle valve 42 provided in the carburetor 41 and a throttle actuator 43 connecting the throttle valve 42.
The throttle actuator 43 operates based on throttle information (signal) of the accelerator pedal device 11 to open and close the throttle valve 42.

  In addition, the vehicle speed increase / decrease member 36 should just be what increases / decreases an engine speed with the accelerator pedal apparatus 11, and the structure is arbitrary.

  Specifically, the accelerator pedal device 11 is a gasoline engine (based on the information of the pedal mechanism 13 disposed in the driver's seat 26, the momentum detection sensor 46 connected to the pedal mechanism 13, and the momentum detection sensor 46). A drive source control unit 47 that controls the wheel drive device 21, and an exercise amount display unit 48 that is connected to the drive source control unit 47 and displays the exercise amount of the driver M.

FIG. 2 is a perspective view of the pedal mechanism (first embodiment) provided in the accelerator pedal device of the present invention. This will be described with reference to FIG.
The pedal mechanism 13 includes a pedal unit 51 that is stepped on with a foot, a support unit 52 that supports the pedal unit 51 in a freely rotatable manner (B-axis direction), and an operation conversion unit that is connected to the support unit 52 and receives force from the pedal unit 51. 53 and a pulling cable 54 connected to the operation conversion unit 53.
The pull cable 54 is connected to the hydraulic pressure increasing mechanism 31 of the wheel brake device 27 and is pulled in the direction of the arrow a1 by the operation conversion unit 53.

  That is, the pedal mechanism 13 includes a motion operation input unit (pedal unit) 51 to which a force resisting the motion load is applied, and a force transmitted from the motion operation input unit 51 is rotated (B axis direction) or linearly moved (X axis or Z axis). And an action conversion unit 53 that converts the direction). Reference numeral 55 denotes a pedal body on which a foot is placed.

  Specifically, the operation conversion unit 53 engages with the normal rotation member 56 that rotates forward (in the direction of arrow a2) when the pedal unit 51 rotates in the normal direction (in the direction of arrow a2). The momentum detection sensor 46 is connected to the forward rotation member 56, and the pulling cable 54 is connected to the ring member 57. The ring member 57 is engaged with the forward rotation member 56 only when the pedal portion 51 is reversely rotated (in the direction of arrow a3) and the normal rotation member 56 is reversely rotated (in the direction of arrow a4). The pulling cable 54 is pulled in the direction of the arrow a1 by the rotation of 57 (the direction of the arrow a4).

The momentum detection sensor 46 is drive-by-wire, for example, measures the number of rotations and angular velocity, detects the momentum, and outputs it to the drive source controller 47, and its configuration is arbitrary.
The drive source control unit 47 employs drive-by-wire with the momentum detection sensor 46, and is connected to the vehicle speed increasing / decreasing member 36 on the gasoline engine (wheel drive device) 21 side, and is set in advance to the pedal unit 51. The throttle opening degree of the vehicle speed increasing / decreasing member 36 (throttle valve 42) is controlled based on the relationship between the pedal rotation speed and the vehicle speed increasing / decreasing member 36 (see FIG. 3).

FIG. 3 is a graph showing the relationship between the pedal rotation speed and the operation amount of the vehicle speed increasing / decreasing member, in which the horizontal axis is the pedal rotation speed Np of the pedal portion 51 and the vertical axis is the throttle opening S of the throttle valve 42. It is.
When the pedal rotation speed Np is zero, the throttle opening S of the throttle valve 42 is zero and the throttle valve 42 is closed.
As the pedal rotation speed Np increases, the throttle opening S of the throttle valve 42 increases.

  In the accelerator pedal device 11, the drive source control unit 47 is drive-by-wire. By using drive-by-wire, the degree of freedom in setting the gradient of the line shown in the graph of FIG. The degree of freedom of setting can be increased.

Next, the operation of the accelerator pedal device of the present invention will be described with reference to FIGS.
When the driver M sitting on the driver's seat 26 “turns on” the switch and then steps on the pedal portion 51 in the forward rotation direction (the direction of the arrow a2), the throttle valve 42 opens and the automobile 12 travels due to gasoline combustion. The driver M can exercise.

  Specifically, when the pedal unit 51 is stepped in the forward rotation direction (the direction of the arrow a2), the momentum detection sensor 46 detects, for example, the number of rotations. Therefore, the drive source control unit (drive-by-wire) that has received the number of rotations information. 47) drives the throttle actuator 43 based on the rotational speed information, thereby opening the throttle valve 42 by an amount corresponding to the pedal rotational speed of the pedal portion 51 as shown in FIG. As a result, the automobile 12 can be driven.

  Thus, in the accelerator pedal device 11 of the automobile 12, the wheel drive device (gasoline engine) 21 is detected based on the momentum detection sensor 46 that detects the momentum applied to the pedal mechanism 13 during driving and the information on the momentum detection sensor 46. And a drive source control unit (drive-by-wire) 47 to be controlled. Therefore, when driving the automobile 12, the driver M needs to continuously step on the pedal unit 51. The lack of exercise can be resolved.

Conversely, when the pedal unit 51 is stepped in the reverse rotation direction (the direction of the arrow a3), it rotates by the reverse rotation angle θ, so that the pulling cable 54 is pulled as shown by the arrow a1 and the hydraulic pressure increasing mechanism 31 is activated. As a result, the caliper 32 is operated to press the disc, thereby braking the front wheel 23. At the same time, naturally, although not shown in the drawing, the rear wheel 24 is braked. As a result, it is not necessary to move the foot to another brake pedal, and the pedal change time can be extremely shortened .

  Further, in the accelerator pedal device 11 of the automobile 12, since the pedal portion 51 is disposed at a position where the foot of the driver's seat 25 is stepped on, it is possible to ensure the same foot space as in the case of a conventional accelerator pedal. .

In the accelerator pedal device 11, the momentum display unit 48 can grasp the momentum of the driver M who is driving one by one.
Further, by connecting, for example, a pulse detection sensor for detecting the pulse of the body to the momentum display unit 48 wirelessly, the pulse of the driver M during driving can be grasped one by one. The lack of exercise can be resolved more effectively.

Next, a method for operating the accelerator pedal device for an automobile according to the present invention will be described.
FIG. 4 is a flowchart for explaining the operation method of the accelerator pedal device of the present invention. This will be described with reference to FIG.

ST01: Sit in the driver's seat 25 and rotate the pedal 51 in the forward direction (in the direction of arrow a2 in FIG. 2) with feet.
ST02: The momentum of the driver M is detected. For example, the rotation speed of the pedal unit 51 is detected.
ST03: It is determined whether or not the amount of exercise (for example, the number of rotations) has increased. When it decreases, the process proceeds to ST06. When it increases, the process proceeds to ST04.
ST04: Output vehicle speed increase information.
ST05: The vehicle speed increasing / decreasing member is operated based on the vehicle speed increase information. For example, by driving the throttle actuator 43, the throttle valve 42 is opened by an amount corresponding to the number of forward rotations of the pedal portion 51 as shown in FIG.
ST06: Outputs vehicle speed reduction information when reduction is selected in ST03.
ST07: The vehicle speed increasing / decreasing member is operated based on the vehicle speed decrease information. For example, by driving the throttle actuator 43, the throttle valve 42 is closed by an amount corresponding to the number of forward rotations of the pedal portion 51 as shown in FIG.

  Here, when the pedal unit 51 is rotated, fuel supply is started. However, even if the pedal unit 51 is rotated, a condition may be set in which fuel is not temporarily supplied. For example, when waiting for a signal at an intersection, the pedal unit 51 may be rotated with the power to the momentum detection sensor 46 disconnected by selecting a “stop button” arranged on the instrument panel. , You can exercise during the signal waiting time.

  Thus, in the operation method of the accelerator pedal device 11 of the automobile 12, the vehicle speed increasing / decreasing member 36 (mainly the throttle valve 42) of the wheel drive device (gasoline engine) 21 is controlled according to the momentum of the driver M who is driving. The vehicle speed is increased / decreased. Specifically, the momentum of the driver M is detected, the increase / decrease in the momentum is determined, and when the momentum increases, the vehicle speed increase information corresponding to the momentum is output and the momentum decreases. The vehicle speed decrease information corresponding to the amount of exercise is output, and the vehicle speed increase / decrease member 36 (mainly the throttle valve 42) is controlled based on the vehicle speed increase information or the vehicle speed decrease information. If you step 51 and the amount of exercise increases, the vehicle speed increases. That is, in order to drive the automobile 12, the driver M needs to continuously step on the pedal portion 51, and the lack of exercise of the driver M during driving can be solved.
