Abstract

The invention discloses an automobile rear-ending avoidance alarming device and method. The alarming device comprises a millimeter wave radar, a single chip microcomputer and an alarming indicating unit, wherein the alarming indicating unit is composed of a lamp driving circuit and an alarming indicator lamp; the single chip microcomputer can output control signals to the lamp driving circuit the positions and speeds of the automobile as well as an automobile ahead, which are collected by the millimeter wave radar. By means of the positions and speeds of the automobile and the automobile ahead and a trained Sugeno-type fuzzy inference system model loaded in the single chip microcomputer, the alarming method can help obtain an expected acceleration of the automobile, when the single chip microcomputer determines that the expected acceleration is smaller than a set acceleration, the single chip microcomputer outputs control signals to drive the alarming indicator lamp to flicker and accordingly to timely issue alarm to the driver of the rear automobile before the automobile brake suddenly, so that the rear-ending accident due to untimely reaction of the driver of the rear automobile can be effectively avoided, further driving security can be enhanced.

Description

technical field [0001] The invention relates to an automobile safety technology, in particular to an early warning device and an early warning method for preventing rear-end collisions of automobiles, which are used to guide drivers to adopt safe driving behaviors and reduce the risk of secondary rear-end collisions by rear vehicles. Background technique [0002] The important research direction in road traffic safety is the research of the automobile itself, which specifically includes two aspects: one is the passive safety technology of the automobile, that is, the technical measures adopted to reduce the loss of property or personnel after the accident; the other is the active safety technology of the automobile. Safety technology refers to the measures taken to prevent accidents before accidents happen. The progress of automobile passive safety technology, such as enhancing the strength of automobile frame structure, adding safety devices such as airbags and safety belts...
