A device and method for remediating accidental stepping on the accelerator pedal of an automobile

Abstract

In recent years, the accidents that an accelerator pedal is mistakenly stepped happen frequently, most of the devices for preventing mistaken stepping on accelerators judge whether or not an accelerator pedals are mistakenly stepped according to the accelerator pedal change rate. When the accelerator pedals are mistakenly stepped, the rates vary from man to man, so that whether or not the accelerator pedals are mistakenly stepped is not likely to be judged by using a uniform change rate. When the mistaken stepping on accelerator pedals is studied, the researchers find that, in any running state of the vehicle, the opening-degree of the accelerator pedal exceeds 90% when the accelerator pedal is mistakenly stepped, so that judging whether or not the accelerator pedal is mistakenly stepped, according to the opening-degree of the accelerator pedal, is feasible. The invention provides a device which can judge whether or not the accelerator is mistakenly stepped according to the accelerator pedal opening-degree, and immediately sends an accelerator pedal initial signal (position signal of the accelerator pedal when the accelerator pedal is not stepped) to an Electronic Control Unit (ECU) when the accelerator pedal is mistakenly stepped by a driver. In addition, the device further has an accelerator pedal opening-degree-reminding function, when the driver steps on the accelerator pedal with a rush, the condition that the opening-degree of the accelerator pedal exceeds the opening-degree threshold value set for judging whether or not the accelerator pedal is mistakenly stepped is avoided.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to a remedial device and control method for accidental stepping on the accelerator pedal of an automobile. Background technique [0002] In recent years, the accidents of accidentally stepping on the accelerator pedal have continued, but there are almost no devices in the market that can effectively reduce the accidents of accidentally stepping on the accelerator pedal. The difference is very large, and the rate when the accelerator pedal is stepped on by mistake varies from person to person, and it is impossible to use a uniform rate of change to judge. And some people like to step on the accelerator pedal quickly to achieve rapid acceleration when starting at the traffic light, so it is easy to make mistakes to judge whether to step on it by mistake according to the rate of change of the accelerator pedal.

[0002] In recent years, the accidents of accidentally stepping on the accelerator pedal have continued, but there are almost no devices in the market that can effectively reduce the accidents of accidentally stepping on the accelerator pedal. The difference is very large. The rate of accidental stepping on the accelerator pedal varies from person to person. It is impossible to use a uniform rate of change to judge

And some people like to step on the accelerator pedal quickly to achieve rapid acceleration when starting at traffic lights, so it is easy to make mistakes in judging whether to step on it by mistake according to the rate of change of the accelerator pedal

[0003] Patent No. 201510424031.4 proposes a device and method for remediating the wrong step on the accelerator of an intelligent car. This invention proposes to input the parameters of the accelerator pedal in advance to distinguish whether the wrong step on the accelerator occurs. The judgment of false accelerator pedal is effective, but in real life, a car is often not driven by a driver, so when changing the driver, it is necessary to change its built-in parameters, which will increase the cumbersome operation virtually and cause problems. The risk of forgetting to change parameters

[0004] When studying the accidental stepping on the accelerator, it is found that in any running state of the vehicle, when the accelerator pedal is accidentally stepped on, the opening of the accelerator pedal exceeds 90%. Therefore, it is feasible to judge whether the accelerator pedal is accidentally stepped on by the opening of the accelerator pedal. However, some drivers who like the "push back feel" like to step on the accelerator pedal quickly when passing traffic lights or pursuing rapid acceleration. At this time, some accelerator pedal openings will still exceed 90%.
