Abstract

The invention discloses a method of judging accelerator instead of brake and a method of automatic brake. The method is implemented by a single chip microcomputer with preset program, and a set of misoperation detecting system, a set of oil circuit controlling system and a set of brake controlling system, which are connected with the single chip microcomputer; the misoperation detecting system includes an acceleration sensor disposed on lower surface of the accelerator, a distance detecting sensor disposed on front terminal of vehicles, and an inclination sensor disposed on vehicle body; the oil circuit controlling system includes an oil-cut solenoid valve which is connected with and controlled by the single chip microcomputer; the brake controlling system includes an armature disposed ona connecting rod of the brake board, an electromagnet adjacented with the armature is disposed on rear of the connecting rod, circuit loop of the electromagnet is connected with and controlled by thesingle chip microcomputer. The method increases judgement condition of error brake of vehicles, such that judgement of error accelerator of drivers is more accurate, reliable, which avoids accidents caused by inaccurate judgement.

Description

technical field [0001] The invention relates to a method for judging whether a driver steps on the gas pedal by mistake when braking an automobile and an automatic braking method. Background technique [0002] With the rapid development of my country's economy, people's living standards continue to improve, and their purchasing power continues to increase. More and more cars "enter" families. In recent years, the number of automobiles in my country has risen linearly and has exceeded tens of millions. With the development of the automobile industry, the safety problem of automobile driving has become more and more prominent, especially the traffic accidents caused by the driver's misoperation during driving, which has aroused great concern of the society. [0003] At present, the accelerator pedal and brake pedal of automobiles are controlled alternately by one foot, which easily causes novice drivers and careless old drivers to mistake the accelerator pedal for braking whe...
