Device for preventing false accelerator stepping under condition in need of emergency braking

Abstract

The invention discloses a device for preventing false accelerator stepping under a condition in need of emergency braking. The device comprises a false steeping detection unit, an accelerator position detection unit, a control unit and a brake unit, wherein the false stepping detection unit is arranged below an accelerator pedal and used for detecting the stepped condition of the accelerator pedal; the accelerator position detection unit is used for detecting the position of the accelerator pedal; the control unit is used for receiving signals from the false stepping detection unit and the accelerator position detection unit, and sending out control signals to the brake unit through conversion, analysis and calculation; and the bake unit is connected with the brake pedal through a stay wire and is used for receiving the control signals sent out by the control unit so as to realize the linkage between the brake pedal and the accelerator pedal. By means of the device disclosed by the invention, when false stepping behaviors of a driver occur, a braking function of the accelerator pedal can be obtained through switching rapidly, so that the occurring rate of traffic accidents of the type can be decreased.

Description

technical field [0001] The invention relates to the technical field of automobile braking devices, in particular to a device for preventing accidental stepping on the accelerator when emergency braking is required. Background technique [0002] At present, the accelerator and brake used in vehicles are controlled by the right foot. When driving normally, step on the accelerator with the right foot. When an abnormal situation is found and emergency braking is required, the right foot needs to be lifted to separate the right foot from the accelerator pedal and move to the brake. Pedal, step on hard just to activate brake device, make car stop. However, in an emergency, the driver is overly nervous, especially for a new driver, who makes a mistake and steps on the accelerator by mistake, causing the vehicle not only to not stop, but to rush forward faster, resulting in a more serious accident. How to better avoid the occurrence of such accidents, there are researches in this a...

AI Technical Summary

Problems solved by technology

However, these designs and studies still have the following problems and defects: (1) the existing car body structure needs to be modified; (2) the cost is high and the cost performance is low, which is not conducive to popularization

Due to the lack of effective linkage between the accelerator pedal and the brake pedal, even if a false step can be detected, the accident cannot be effectively avoided
