Abstract

The invention provides a road condition monitoring and safety protection method which is applicable to a safety belt and an electric retractor used for retraction of the safety belt. The method includes the steps: detecting the distances of vehicles by range radars arranged on front and rear bumpers and side door posts of the vehicles, and outputting ranging signals; converting the ranging signals into digital signals; comparing the ranging signals with a reference value, and outputting comparison results; starting and stopping a vibrator mounted below a driver seat according to the comparison results, and enabling the vibrator to generate high-frequency low-amplitude vibrations when the ranging signals are smaller than the reference value; subjecting the ranging signals to acceleration detection by the aid of a virtual timer arranged in a controller, and controlling the electric retractor to retract the safety belt when the acceleration reaches a preset value.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a road condition monitoring and safety protection 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. [0...
