A kind of accelerator anti-accidental stepping and active braking system and active braking method thereof

Abstract

The invention discloses an accelerator anti-misstepping and active braking system and an active braking method thereof. The invention provides an anti-misstepping accelerator system, which comprises an active brake electromagnetic tube, an anti-misstepping electromagnetic tube of the accelerator, a base plate, a controller, a front-view camera, a camera at the bottom of the pedal, and a safety button. The two ends of the accelerator anti-misstepping electromagnetic tube are respectively hinged with the base plate and the accelerator pedal. The two ends of the active brake electromagnetic tube are respectively hinged with the base plate and the brake pedal. The structure of the active brake solenoid and the accelerator anti-misstepping solenoid is the same, including the upper lifting lug, the upper iron core, the upper excitation coil, the lower lifting lug, the lower iron core, the lower excitation coil, the main telescopic tube, the return spring and the rubber anti-corrosion dust jacket. The present invention can be used to transform the existing vehicles without automatic braking function, and only through simple installation, the functions of anti-misstepping on the accelerator and automatic braking of the vehicle can be realized; and the present invention can use Electromagnetic repulsion prevents the driver from stepping on the accelerator pedal, and uses electromagnetic attraction for automatic braking.

Description

technical field [0001] The invention belongs to the technical field of automobile active safety technology, and in particular relates to a method and system for preventing misstepping on the accelerator and active braking. Background technique [0002] In recent years, the number of domestic cars has increased year by year, and the number of cars in 2020 will reach 630 million or become the world's number one. The resulting traffic congestion problem is becoming more and more prominent, and the traffic accident rate is also increasing year by year. Among the various causes of traffic accidents, traffic accidents caused by using the gas pedal as a brake account for more than 40%. According to the incomplete statistics of the transportation department, there are about 90,000 accidents caused by using the gas pedal as a brake every year; about 100,000 people are injured; about 25,000 people die. According to statistics, most of the drivers who are easy to step on the accelera...

Problems solved by technology

Although this method can accurately judge misstepping, it needs to change the wiring harness inside the car, which is complicated to install and it is difficult for the car ECU to receive external control commands.
