Automobile Braking System with Micro-clutch Type Accelerator Error Correction Device

Abstract

A pressure trigger switch-type accelerator pedal system used to correct mistaken use of an accelerator for braking, classed as an accelerator system able directly to obtain a signal indicating that the accelerator has been pressed incorrectly. A pressure trigger switch (1) is provided on the front surface or rear surface of the accelerator pedal (16), or alternatively, a pressure trigger switch (1) is provided at the part of the car bodywork (21) corresponding to the accelerator pedal (16); when a spring element in the pressure trigger switch is deformed by pressure at the switching threshold, two conducting contact elements of the switch are brought into contact, generating a switch that is switched on so that it conducts electricity; the position in which the pressure trigger switch (1) is disposed enables the switching threshold to correspond to the threshold for incorrect accelerator-pedal use; the pressure trigger switch (1) is connected to a trigger signal converter (35). The present accelerator pedal system is able directly to obtain a signal indicating that the accelerator has been pressed incorrectly, and there is no need to use a pressure sensor with a microelectronic circuit to analyse actions of accelerator-pressing at different pressures to determine whether the accelerator has been pressed incorrectly; the system has a fast response speed, simple structure, low cost and small volume; the system is easy to install, and is a reliable system for obtaining a signal indicating incorrect pressing of an accelerator.

Description

technical field [0001] The invention belongs to the technical field of brakes for automobiles, in particular to a brake system for automobiles capable of transforming the mechanical action of stepping on the gas pedal by mistake into an automatic braking mechanical action. Background technique [0002] In his authorized patent 200510022077.X "throttle system device with annunciator", the applicant provides a device that has the ability to judge whether the throttle action is correct or wrong before determining whether to remedy and brake, so that the throttle can be controlled. A motor vehicle accelerator pedal system capable of moving and accelerating. It is characterized in that an annunciator is arranged on any one of the accelerator pedal, the linkage device and the vehicle body device. The annunciator is connected with the electric valve that can cut off the engine oil circuit and the electric valve on the wheel brake. This technology proposes to use electronic settin...

Problems solved by technology

The first disadvantage of this technology is that the continuously changing pressure signal sensed by the annunciator is taken out of the misstepped accelerator signal. When the signal acquisition device fails, it may cause errors in the judgment of the misstepped accelerator signal, resulting in poor reliability of the system.

The second disadvantage of this technology is to use the signal output line to control the electric valve, and use the electric valve to control the vehicle's engine oil supply pipe, ignition circuit, motor power supply and other power sources of the vehicle, so that the driver will accidentally step on the accelerator until the vehicle is stopped. Long, the vehicle has a long trip to make an error, and this slow response is not good for preventing traffic accidents.

[0003] In his patent application 201110030092.4 "A Device for Automatically Correcting Misstepped Accelerators to Brakes with Electric Appliances and Machinery", the applicant disclosed a device including a sensor, a signal analyzer and a brake activation mechanism. There are many microelectronic devices for stepping on the accelerator signal, and the reliability is reduced; the second disadvantage is that in the brake starting mechanism, the circular motion of the motor is changed into the reciprocating motion of the brake rope, and the straight rack is used to change the motion mode, because it needs The reciprocating motion of the positioning of the straight rack requires a frame that fixes the relative position of the motor and the straight rack. This frame is bulky and difficult to find a suitable position for installation, and has a complex structure, high cost and poor reliability.
