Problems solved by technology

However, the current way of setting the radar to remind the driver is that the accuracy rate of the early warning is relatively low, and the probability of false alarm is very high, which causes a lot of inconvenience to the driver. In addition, the radar in the prior art is often aimed at a certain angle range. Scanning without a radar system for monitoring, calibrating, confirming and judging

Abstract

The invention provides an automobile anti-collision early warning method, which is realized through an automobile anti-collision early warning device. A central processor controls first-fifth radar sensors to obtain distances between the radar sensors and a barrier respectively; modeling calculation is carried out through a trigonometric function to obtain perpendicular distance from the tail portion of an automobile to the barrier; and when the perpendicular distance is larger than or equal to a threshold value, an alarm is given. Therefore, large range monitoring can be realized, alarm accuracy is high, cost is low, and measurement error is effectively eliminated.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to an automobile anti-collision early warning method. Background technique [0002] Public transportation safety is a matter of great concern to the public, and driving safety is a major issue for car drivers. In many traffic accidents, collision is a frequent accident form, and the ratio of side and rear collisions is very high. Side and rear collisions usually occur at intersections, changing directions, overtaking, reversing, etc., causing great damage to the vehicle and high maintenance costs. How to effectively and accurately remind drivers to prevent automobile collisions has become a very hot issue. [0003] At present, the existing anti-collision methods of automobiles are mainly to install bumpers on the front and rear of the automobile, install airbags and safety belts to protect the driver and passengers, and also by setting radar on the surrounding body of the automobi...
