Description

TECHNICAL FIELD

[0001] The present application relates to the field of automotive technology, in particular to a front seat test system device for a car. BACKGROUND

[0002] The comfort and intelligence of a car seat, as an important part of a car, directly affect the level of advancement of the car. The car seat carries the largest part of the interaction between the person and the car. The level of the seat and the intelligence of the seat itself can greatly reflect the level of advancement of a car or even a class of cars. Based on the above factors, car manufacturers assign special connotations to car seats when the car project is established. The appearance, service life, comfort, technology, intelligence, and even assembly and maintenance are defined one by one. The car seat determines the way of judging people and objects through the conduction of the pressure sensing part.

[0003] Most of the pressure sensing judgments of the front seat on the market are one-level judgments, that is, only by judging whether the total weight exceeds a certain weight to determine whether there is a person or an object on the front seat. This judgment method has a large misjudgment rate, such as being unable to determine whether a backpack containing certain objects or a shopping bag full of objects is placed on the seat or a child or an adult is sitting on the seat. The weight sensor detection basis is insufficient, which affects the accuracy and reliability of the seat object weight sensing, and brings certain hidden dangers to the quality control of car production.
