A Combined Electronic Accelerator Pedal

Abstract

The invention discloses a combined electronic accelerator pedal. The combined electronic accelerator pedal comprises a carpet type part and a suspension type part, wherein the carpet type part comprises a carpet type pedal arm, a carpet type pedal base and a universal transmission component; the suspension type part comprises a suspension type pedal arm, a suspension type pedal base, a side cover, a shell, a sliding block 1, a sliding block 2, a spring base, an elastic sheet, a base sheet, an inner spring, an outer spring, a sealing ring, a wear-resistant piece, a rotating shaft, hardware terminals, self-tapping screws and a universal transmission component side cover. The electronic accelerator pedal can more accurately reflect the intention of drivers, reduces the damage of the drivers to the electronic accelerator pedal in the driving process, prolongs the service life of the electronic accelerator pedal and reserves the driving comfort brought by the carpet type pedal by means of the carpet type part.

Description

technical field [0001] The invention relates to the field of pedals, in particular to a combined electronic accelerator pedal. Background technique [0002] With the improvement of social and economic level, people's demand for life is also constantly improving. Nowadays, vehicles have become a necessary tool for people to travel. In recent years, with the increasing number of various vehicles, people have higher and higher requirements for car performance. With the increase of the intelligence of cars, more and more sensors are used in cars. Accelerator pedal is an important part of automobile intelligent control. When the motor vehicle needs to accelerate, the driver manipulates the electronic accelerator pedal, and the electronic accelerator pedal position sensor generates a corresponding voltage signal and transmits it to the electronic accelerator pedal controller. The working mode, pedal movement and change rate analyze the driver's intention, process the input signa...

AI Technical Summary

Problems solved by technology

[0003] The current electronic accelerator pedals are roughly divided into two types: suspension type and carpet type. The carpet type is much better than the suspension type in terms of comfort and handling performance. Most high-end vehicles use carpet type pedals, although carpet type pedals are better than suspension types. However, the suspended and carpeted pedals are the products of the ideal design concept, and there are practical defects. As we all know, when the driver manipulates the electronic accelerator pedal with his foot, he steps on the arm of the electronic accelerator pedal. , the position and direction of the foot may not be in the center of the design of the pedal arm and the pedal base, which will cause uneven force on the pedal arm (because we design both the suspension type and the carpet type pedal arm and the pedal base) According to the ideal state), when the pedal arm with uneven force operates under the action of the pedal force, the pedal arm must tilt along the center of gravity of the driver's foot, and it may be left or right. When the pedal arm is tilted, a displacement deviation will inevitably occur relative to the ideal state of the pedal arm (the displacement of the pedal in the normal state and the displacement of the pedal in the tilted state), this deviation does not cause the car to not drive according to the driver's intention , so that the car driver is in an ideal state of illusion, which is a kind of deception to the driver. When the pedal arm is unevenly stressed for a long time, it will inevitably lead to the deviation of the pedal arm towards the center of gravity of the driver's habitual force. The friction between the arm and the side of the pedal base will cause noise when the electronic accelerator pedal of the car is in use, and it is more likely to cause the electronic accelerator pedal to be stuck, threatening the driver's life safety

It can be seen that no matter whether it is a suspension type or a carpet type, there are hidden dangers of the above safety and deceiving drivers.
