Motor vehicle driver safety belt unfastening prompting system

Abstract

The invention discloses a motor vehicle driver safety belt unfastening prompting system. The system comprises a seat pressure sensing module, a safety belt magnetic force sensing module, a vehicle driving state detection module and a safety belt unfastening prompting module, wherein the seat pressure sensing module is used for judging whether a driver sits on the seat or not by detecting the seatpressure; the safety belt magnetic force sensing module judges whether the driver fastens the safety belt or not by detecting the magnetic force on the safety belt; the vehicle driving state detectionmodule judges whether the vehicle is in a driving state or not by detecting the vehicle driving state; and the safety belt unfastening prompting module prompts a driver and passengers to fasten the safety belt. According to the system, through cooperation of all the modules, whether the driver fastens the safety belt or not during vehicle driving can be detected, and the driver is reminded to fasten the safety belt in time. According to the system, the cost can be reduced while the safety belt unfastening recognition performance is improved. The system can accurately remind the driver and passengers to fasten the safety belt, safety risks are reduced, and the detection accuracy is high.

Description

technical field [0001] The invention belongs to the technical field of automobile safety protection, and relates to a prompt system for motor vehicle drivers not wearing safety belts. Background technique [0002] With the continuous development of the automobile industry, the number of cars is getting higher and higher, and there are more and more safety accidents. In order to avoid the safety accident and reduce the harm to the driver and passengers after the safety accident, the current car seat Almost all cars are equipped with seat belts. As the most effective driver and occupant protection device, seat belts occupy an important position in car protection devices. However, many passengers often choose not to wear seat belts for the sake of convenience during the ride, which can easily lead to some accidental tragedies that could have been avoided. [0003] The existing safety belt wearing detection method is mainly based on the method of pressure sensor + electronic bu...

However, many passengers often choose not to wear seat belts for the sake of convenience during the ride, which can easily lead to some accidental tragedies that could have been avoided.

[0003] The existing safety belt wearing detection method is mainly based on the method of pressure sensor + electronic buckle, which is slightly expensive, and the driver often buys a replacement buckle and puts the seat belt behind the method to avoid detection, which is easy to cause mistakes sentence
