Problems solved by technology

The first disadvantage of this technology is that in the continuously changing pressure signal felt by the annunciator, when the signal acquisition device for judging and taking out the false accelerator pedal signal is faulty, it may make an error in the judgment of the false accelerator pedal signal, resulting in the failure of the system. poor reliability
The second disadvantage of this technology is to use the signal output line to control the electric valve, and use the electric valve to shut off the engine oil supply pipe, ignition circuit, motor power supply, etc. of the vehicle, so that the driver has a long time to step on the accelerator by mistake until the vehicle is stopped. The wrong trip is far away, and this slow response is not conducive to preventing car accidents from happening
The third disadvantage of this technology is to use the signal output line to control the electric valve, and use the electric valve to cut off the engine oil supply pipe, ignition circuit, motor power supply, etc. of the vehicle, so that the engine will stop rotating and work completely, causing the brake system and steering of the car to be damaged. system, anti-skid and other safety systems have all stopped working, so shutting off the engine of the vehicle with a false accelerator pedal signal is not conducive to performing error-correcting emergency braking when there is a false accelerator pedal
[0003] In his patent application 201110030092.4 "A Device for Automatically Correcting Misstepped Accelerators to Brakes with the Coordination of Electric Appliances and Machinery", the applicant disclosed a device including sensors and signal analyzers And the device of the brake starting mechanism, its disadvantages are that there are many microelectronic devices to obtain the signal of the accelerator pedal by mistake, and the reliability is reduced; the disadvantage is that in the brake starting mechanism, the circular motion of the motor is changed For reciprocating motion, the straight rack is used to change the motion mode, because to ensure the reciprocating motion of the straight rack positioning, it is necessary to have a frame that fixes the relative position of the motor and the straight rack. This frame is bulky and it is difficult to find a suitable position. installation, and complex structure, high cost and poor reliability

Embodiment 1

[0057] Embodiment 1. The spring-type pressure trigger switch is located on the back of the accelerator pedal, and the gas pedal system with pressure trigger switch is used for correcting the wrong step on the accelerator.

[0058] like figure 1 , 4 , 5, 6,

[0059] [1] The structure of the switch: the structure of the pressure trigger switch 1 of this embodiment is that the spring type pressure trigger switch 1 includes a sliding cylinder 26, an inner hollow coil spring 27, a cross-shaped piston 28 and two conductive contacts 25; Type coil spring 27 is located among the slide tube 26, and the two ends of hollow type coil spring 27 contact the bottom of slide tube 26 and the piston disc of cross-shaped piston 28 respectively; At the top, one section of the middle post 29 of the cross-shaped piston 28 stretches out from the middle hole of the top cover 31 of the middle hole in the sliding cylinder 26. The other section of 29 is located in the coil of the hollow coil spring 27...

Embodiment 2

[0070] Embodiment 2. The spring-type pressure trigger switch 1 is located at the corresponding car body part on the back of the accelerator pedal, and the gas pedal system with pressure trigger switch is used for correcting the wrong step on the accelerator.

Abstract

The invention relates to a pressure-triggered switch type accelerator pedal system for preventing an accelerator from being used as a brake, which belongs to an accelerator system capable of directly acquiring a false accelerator stepping signal. A pressure-triggered switch is arranged on the front or back of an accelerator pedal or on a body part corresponding to the accelerator pedal, and the pressure-triggered switch is a switch which enables two conductive contacts to be in contact with each other to conduct electricity after an elastic element in the switch is deformed by switch threshold pressure, the position where the pressure-triggered switch is arranged ensures that a switch threshold corresponds to a false stepping threshold, and the pressure-triggered switch is connected with a trigger signal converter. The pressure-triggered switch type accelerator pedal system has the advantages that: the pressure-triggered switch type accelerator pedal system can directly acquire the false accelerator stepping signal, and does not need a pressure sensor with a microelectronic circuit to analyze accelerator stepping acts with different weights to find out false accelerator stepping acts, the response of the system is quick, the structure is simple, the cost is low, the size is small, and the system is easy to mount, and is a highly-reliable accelerator system which can directly acquire the false accelerator stepping signal.
