Safety belt and safety belt wearing identification method and device thereof

Abstract

The embodiment of the invention discloses a safety belt and a safety belt wearing identification method and device thereof. The safety belt comprises a belt body and an identifiable mark arranged on the belt body. The identifiable identifier comprises a first identifier with an infrared reflection function and / or a second identifier with an infrared transmission function. Through the scheme of the embodiment, judgment of the state of the safety belt is not affected by the color of a coat of a person and light in a vehicle, misjudgment is reduced, and cost is reduced.

Description

technical field [0001] The embodiments of the present application relate to vehicle safety technology, and more particularly, to a seat belt and a method and device for recognizing the wearing of the seat belt. Background technique [0002] At present, the identification of the status of the seat belt mainly relies on the lock sensor. When the seat belt tongue is inserted into the lock, the sensor in the lock is triggered to identify the seat belt. However, this method has a drawback: if the occupant uses a separate latch (the one that is not connected to the seat belt) to insert the buckle, the sensor will still send a signal that the seat belt is fastened, and the car will misjudge that the occupant is fastened. bring. [0003] At present, there is also a method of identifying whether the driver has fastened a seat belt through a picture, and this method also has some defects: 1. If the color of the seat belt is similar to the color of the driver's chest, it is difficult ...

Problems solved by technology

However, there is a flaw in this method: if the occupant uses a separate deadbolt (the one that is not connected to the seat belt) to insert the buckle, the sensor will still send out a signal that the seat belt has been fastened, and the car will mistakenly judge that the occupant is fastened. bring

[0003] At present, there is still a method of identifying whether the driver has worn a seat belt through a picture, and this method also has some defects: 1. If the color of the seat belt is similar to the color of the driver's chest clothes, it is difficult to judge the driver's chest according to the picture. Whether there is a seat belt in the front; 2. If the light inside the car is dark or driving at night, the pictures taken may not reflect the real scene inside the car due to too dark light
