Braking method and breaking device for mistakenly stepping on accelerator during braking

Abstract

The invention discloses a braking method for mistakenly stepping on an accelerator during braking, and a braking device using the method and suitable for a situation when the accelerator is mistakenly stepped on during braking. The braking method compares the time Tx required by the accelerator to move from a starting position to an ending position with the preset time T for judging the mistaken stepping on the accelerator so as to judge whether the accelerator is used as a brake; the braking device suitable for the situation when the accelerator is mistakenly stepped on during braking has high working efficiency and precise and scientific monitoring process, judges whether the accelerator is mistakenly stepped on by measuring the time for the accelerator to change at two limiting positions, can also improve the capability of resisting the disturbance of the device, and greatly ensures the stable running of the braking device; simultaneously, an electric structure is adopted to improve the response speed of the device; and compared with the mechanical structure in the past, the braking device not only has high response speed, but also has a simple structure and excellent braking effect, and provides safer and more reliable guarantee for vehicle running.

Description

technical field [0001] The invention relates to a braking method for mistakenly stepping on the gas pedal during braking, and a brake device suitable for the case of mistakenly stepping on the gas pedal when braking, which is obtained by using the method. Background technique [0002] In current automobile driving, the driver often uses the accelerator pedal as the brake pedal in an emergency, which causes extremely serious traffic accidents. At present, automobile exhaust emissions require that brake devices be installed on Euro IV and Euro V cars. Reach the purpose of still being able to brake when stepping on the gas pedal by mistake. Such a structure requires an interlocking mechanism, so its structure is very complicated, which does not meet the conventional design requirements of the car, and changes the conventional driving habits, but reduces the safety of the car, and does not meet the requirements of the mandatory regulations of the car, so the There are many dis...

AI Technical Summary

Problems solved by technology

When stepping on the accelerator normally, the device will be activated and the engine will be stopped if the action is slightly faster, so the ability of the device to distinguish correct and wrong operation is low, which brings inconvenience to the application

Since the body is in a sliding state when the engine stops working, the inertia may still drive a long distance; the brake pedal is activated after the connecting pressure lever is pushed by the accelerator pedal, so the sliding state of the body before braking is extremely dangerous

At the same time, the delay characteristics of the transmission of each link mechanism further lags behind the generation of brakes.

Therefore, the wrong step on the accelerator safety brake device provided in the prior art realizes the function of braking in the event of misoperation to a certain extent, but the whole device has slow reflection speed, low anti-interference ability, and complicated structural design.
