Problems solved by technology

[0003] The inventor found in the process of realizing the present invention that for traditional headrests, passengers cannot adjust their softness and hardness according to their own preferences, and it is difficult to meet the comfort requirements of different passengers; The flocculent material has a small deformation and cannot provide enough buffer space for the neck, which is easy to damage the neck and has a low safety factor

Embodiment 1

[0017] figure 1 A flow chart showing a control method of a car seat headrest according to an embodiment of the present invention, which includes:

[0018] S110, receiving driving input information, and generating an inflation command or a deflation command according to the driving input information;

[0019] For example, the received driving input information may be a voice instruction, a button instruction, and the like. In an embodiment of the present invention, the driving input instruction is an instruction input by a passenger.

[0020] If the received driving input information is deflation information, a deflation command is generated. If the received driving input information is inflation information, an inflation instruction is generated.

[0021] S120. Control the inflator to inflate or deflate the airbag according to the inflation command or deflation command.

[0022] For example, according to the inflation instruction, the inflator is controlled to inflate the ...

Embodiment 2

[0025] On the basis of the first embodiment of the present invention, a further improvement is made. Optionally, after S120, S130 may also be included, such as figure 2 As shown, specifically:

[0026] S210, detecting the first air pressure in the inflation pipeline;

[0027] The total air pressure in the inflation pipeline can be detected, and the total air pressure can be regarded as the first air pressure. If the airbag includes multiple sub-airbags, it is also possible to detect the sub-air pressure in the sub-inflation pipeline corresponding to each sub-airbag, and use each sub-air pressure as the first air pressure.

[0028] S220, when the first air pressure is greater than the first predetermined air pressure or the first air pressure is less than the second predetermined air pressure, control the inflator to stop inflating or deflated the airbag;

[0029] Specifically, when the first air pressure is greater than the first predetermined air pressure, the inflatable p...

Embodiment 3

[0033] On the basis of Embodiment 2 of the present invention, further improvements have been made, such as image 3 As shown, optionally, S110 includes:

[0034] S310, receiving the driving acceleration;

[0035] Receive the detected driving acceleration during the running of the vehicle in real time. The driving acceleration can be received from the on-board computer or from the acceleration sensor.

[0036] S320, when the driving acceleration is greater than the predetermined acceleration, generate a deflation instruction.

[0037] For example, the driving acceleration of the vehicle is 8 m / s^2, the predetermined acceleration is 4 m / s^2, 8 > 4, and a deflation command is generated, then the control device controls the operation of the inflator to deflate the airbag , reduce the hardness of the airbag, so that when the passenger's neck touches the airbag, the airbag can play a good buffer role to ensure that the passenger's neck is not damaged.

Abstract

The embodiment of the invention discloses a method and device for controlling car seat back cushions and car seats. The method comprises the steps of receiving driving car input information, generating an inflation instruction or a deflation instruction according to the driving car input information, and controlling inflation parts to inflate or deflate airbags of the back cushions according to the inflation instruction or the deflation instruction. According to the provided method and device for controlling the car seat back cushions and the car seats in the embodiment, by adjusting the air pressure in the airbags in the back cushions, passengers can adjust the softness and hardness degree of the seat back cushions according to their own preference, and requirements of different passengers for the comfort degree can be better met.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of automobiles, in particular to a method and device for controlling a headrest of an automobile seat and an automobile seat. Background technique [0002] At present, people spend more and more time in cars, so they have higher and higher requirements for ride comfort, especially for seat comfort. In order to increase comfort, passengers generally install a pillow at the headrest of the seat, and the inside of the pillow is filled with a certain amount of flocculent material. [0003] In the process of realizing the present invention, the inventor found that for traditional headrests, passengers cannot adjust their softness and hardness according to their own preferences, and it is difficult to meet the comfort requirements of different passengers; The floc material has a small amount of deformation and cannot provide enough buffer space for the neck, which is easy to damage the neck ...
