Accelerator pedal system with tension trigger switch for correcting wrong use of accelerator as brake

Abstract

The invention relates to an accelerator pedal system with a tension trigger switch for correcting the wrong use of an accelerator as a brake and belongs to an accelerator system capable of directly acquiring mistaken accelerator pedaling. A front side of a back side of the accelerator pedal is provided with the tension trigger switch, or a vehicle body part, which is far away from the accelerator pedal, is provided with the tension trigger switch, after an elastic element in the tension trigger switch is deformed by the tension of a switch threshold, two conduction contact elements of the switch can be contacted to produce conduction connection, the position of the tension trigger switch makes the switch threshold and a mistaken pedaling threshold corresponding, and the tension trigger switch is connected with a trigger signal converter. The system has the advantages that a mistaken accelerator pedaling signal can be directly acquired, a tension sensor with a micro electronic circuit is not needed for analyzing different degrees of accelerator pedaling to find out mistaken accelerator pedaling action, and the system has a simple structure and a small size, is fast in response and low in cost, is easy to install, and is the accelerator system which has good reliability and directly acquires the mistaken accelerator pedaling signal.

Description

Technical field [0001] The present invention belongs to the technical field of automobile accelerator systems, in particular to an accelerator system that can directly obtain an accelerator signal of misstepping, and can convert the actuation of a misstep accelerator into an accelerator device that drives a brake mechanism. Background technique [0002] In his authorized patent 20051001077.X "Throttle System Device with Annunciator", the applicant provides a device that can determine whether to remedy the brake after judging whether the throttle is correct or wrong, so that the throttle becomes a Braking can accelerate dual-purpose motor vehicle accelerator pedal system. It is characterized in that an annunciator is provided on any device of the accelerator pedal, the linkage device, and the device of the accelerator pedal corresponding to the vehicle body part. The annunciator is connected with the electric valve that can cut off the engine oil circuit and the electric valve th...

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
