Road condition monitoring method

Abstract

The invention provides a road condition monitoring method. The road condition monitoring method comprises the following steps that range radars arranged on a front bumper, a rear bumper and a side door post of an automobile are used for detecting the distances between the automobile and other automobiles, and ranging signals are output; the ranging signals are converted into digital ranging signals; the ranging signals are compared with a reference value, and comparison results are output; a vibrator installed below a driver seat is started or stopped according to the comparison results, and when the ranging signals are smaller than the reference value, the vibrator vibrates in a high-frequency low-amplitude mode; pressure sensors arranged on the periphery of an automobile frame are used for testing the collision pressure of the automobile, and a pressure signal is output; the pressure signal is converted into a digital pressure signal; acceleration detection is conducted on the ranging signals through a virtual timer arranged in a controller, and when acceleration reaches a set value, an electric coiler is controlled to tighten a safety belt; when the pressure signal reaches a set value, an inner cushion air bag is controlled to be started.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a road condition monitoring method. Background technique [0002] The development of automobiles not only has a huge effect on social economy, but also has an important impact on human life. Automobiles have become the main means of transportation for people to travel, and their convenience is unmatched by airplanes, ships and trains. At present, China's car ownership has become the largest in the world, and more and more families own cars. [0003] The seat belt has a cushioning effect. When the vehicle collides or brakes in an emergency, the seat belt can effectively avoid and reduce injuries and protect the lives of the driver and passengers. [0004] Studies have shown that wearing seat belts while driving can save more than 40% of lives in accidents. The seat belt is an essential safety system of the vehicle and the life belt of the driver. [0005] The force-bearing...
