JP3799126B2 - Accelerator pedal device - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an accelerator pedal device.
[0002]
[Prior art]
In recent years, as a throttle valve control system for internal combustion engines for vehicles such as automobiles, the amount of operation of the accelerator pedal is captured as an electrical signal by a sensor instead of the conventional direct throttle valve operation by the accelerator pedal operation. A so-called electronic throttle-type throttle valve control device having a drive unit that performs predetermined arithmetic processing and then supplies it to an actuator made of an electric motor or the like, and controls the opening and closing of the throttle valve by this actuator, has come to attract attention. It is applied to engine control (Japanese Patent Publication No. 6-24888).
[0003]
[Problems to be solved by the invention]
The prior art has a separate actuator drive unit that controls the opening and closing of the throttle valve, which increases the number of parts and increases the number of mounting and connecting work steps for the vehicle.
[0004]
SUMMARY OF THE INVENTION An object of the present invention is to provide an electronic throttle type throttle valve control system that is compact, compact, and inexpensive.
[0005]
[Means for Solving the Problems]
The above object can be achieved by integrating an actuator drive unit that controls opening and closing of a throttle valve with an accelerator pedal device that includes an accelerator sensor that changes an operation amount of the accelerator pedal into an electric signal.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the accelerator pedal device according to the present invention will be described in detail with reference to examples.
[0007]
FIG. 1 is an explanatory view of an electronic throttle mechanism having an accelerator pedal device according to the present invention.
[0008]
A sensor signal 2 relating to the amount of depression of the accelerator pedal 1 is sent to the engine control module 3, and the engine control module 3 sends to the throttle control module 5 a throttle control signal 4 that matches the operating conditions based on the data of various sensors. This is an electronic throttle configuration in which the opening degree of the throttle valve 8 is controlled by driving the motor 7 of the throttle actuator 6 by this control signal.
[0009]
FIG. 2 shows this electronic throttle type accelerator pedal device.
[0010]
FIG. 3 is a developed sectional view taken along the line 9-9 in FIG. In FIG. 3, the levers 10 and 11 and the holder 12 are fixed so as to rotate integrally with a pedal shaft 14 that is rotatably supported by a housing 13 that is a support. The pedal shaft 14 further includes an accelerator sensor 16 that has a holder 15 that rotates integrally with the pedal shaft 14 and uses the rotation amount of the pedal shaft 14 as an electrical signal.
[0011]
The pedal force of the driver applied to the accelerator pedal 1 (FIGS. 1 and 2) is received by the lever 10 via the lots 17 and 18, and the pedal shaft 14 is rotated in accordance with the driver's stepping amount. .
[0012]
In addition, a torsion spring 19 that preloads the pedal shaft 14 in the rotational direction toward the predetermined (Idle) position is hooked between the lever 10 and the housing 13 when the accelerator pedal 1 is not operated by the driver's foot. Has been.
[0013]
In addition to the above structure, the accelerator sensor 16 has a drive unit 22 that controls the opening and closing of the throttle valve 8 (FIG. 1) in a space partitioned by the housing 13, the gasket 20, and the cover 21. Are connected by pins 23.
[0014]
As described above, the drive unit 22 for controlling the opening and closing of the throttle valve 8 is integrated (built in) into the accelerator pedal device having the accelerator sensor 16, and the accelerator pedal device is installed when the system is attached to the vehicle. By mounting, the drive unit 22 is also included, and a compact system configuration that eliminates the need for mounting connection in a vehicle is achieved.
[0015]
【The invention's effect】
According to the present invention, there are provided a part for attaching a drive unit of an actuator for controlling opening / closing of a throttle valve to a vehicle, and a small and compact electronic throttle type throttle valve control system that requires no mounting work and has a small number of parts. Can do.
