A vehicle distance judgment method based on automobile rearview mirror

Abstract

The invention discloses an automobile rearview mirror-based distance judgment method, comprising the following steps: adjusting outside rearview mirrors, concretely, 1, firstly a driver adjusting the seat to an appropriate location, and at the moment, observing the rearview mirrors on both sides, wherein the reasonable range refers to that after the rearview mirrors are unfolded, the driver can observe the automobile body through the mirror surfaces, and the area of the automobile body does not exceed a quarter of the mirror image; 2, adjusting the height, that is, in principle, the distance horizon is positioned at the center of the mirror image when the scene behind the automobile is viewed from the rearview mirrors on both sides, making sure that the angle of the rearview mirror on the right is not adjusted too low, which is not wrong, the angle shall not be adjusted too low, and the reasonable range refers to that the area of a road surface does not exceed two thirds of the area of the mirror surface by taking the distance horizon as the benchmark; and 3, adjusting the central rearview mirror in the automobile easily, concretely, keeping the correct sitting posture and mapping rear windows on the center of the rearview mirror. The automobile rearview mirror-based distance judgment method is fully functional, clear in logic and easy to judge, and the driving safety of the automobile is greatly improved.

Description

【Technical field】 [0001] The invention relates to a method for judging the distance between vehicles, in particular to a method for judging the distance between vehicles based on automobile rearview mirrors. 【Background technique】 [0002] At present, car drivers know that before overtaking, changing lanes, or driving back to the original lane, they need to observe the distribution of vehicles around them.
