Problems solved by technology

[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. Only when safety is ensured can they perform corresponding operations such as overtaking, changing lanes, and driving back to the original lane. In this process, it is relatively easy and convenient for the driver to observe whether there are cars in front and on both sides. However, few car drivers know how to judge the distance between cars through the car rearview mirror.

Embodiment Construction

[0010] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0011] A method for judging distance between vehicles based on automobile rearview mirrors, comprising the following steps:

[0012] (1) How to adjust the exterior rearview mirror: ①Firstly, the driver adjusts the seat to a suitable position, and then observes the rearview mirrors on both sides. After unfolding the rearview mirror, he can observe his own body from the mirror surface, and The body area should not exceed 1 / 4 of the mirror image, which is a reasonable range; ② For height adjustment, in principle, observe the scene behind the car from the rearview mirrors on both sides, so that the far ground plane is in the center of the mirror image. Try not to lower the angle of the right rearview mirror. Although there is nothing wrong with this a...

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. Only when safety is ensured can they perform corresponding operations such as overtaking, changing lanes, and driving back to the original lane. In this process, it is easier and more convenient for the driver to observe whether there are cars in the front and both sides, but few car drivers understand how to judge the distance between cars by the rearview mirror of the car. To this end, we propose a vehicle distance judgment method based on the rearview mirror of the vehicle. 【Content of invention】 [0003] In order to achieve the above object, the technical scheme tha...
