Pressure-triggered switch type accelerator pedal system for preventing accelerator from being used as brake

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.

Description

technical field [0001] The invention belongs to the technical field of automobile accelerator systems, in particular to an accelerator system capable of directly obtaining a signal of a false accelerator pedal, which can convert the action of a false accelerator pedal into an accelerator device for driving a brake mechanism. Background technique [0002] In his authorized patent 20051001077.X "throttle system device with annunciator", the applicant provides a device that determines whether to remedy the brake after judging whether the throttle action is correct or wrong, so that the throttle can be The utility model relates to a dual-purpose motor vehicle gas pedal system which can be used for braking and accelerating. It is characterized in that an annunciator is arranged on any one of the accelerator pedal, the linkage device, and the accelerator pedal corresponding to the vehicle body parts. The annunciator is connected with the electric valve that can cut off the oil ci...

AI Technical Summary

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
