Problems solved by technology

[0002] At present, SUVs and sports cars are very popular in the market. The conventional function is to install a pneumatic lumbar support in the side wing area of ​​the seat to clamp the driver tightly by inflating two airbags at the same time. However, there is no terrain-adaptive inflation and deflation function yet. side lumbar support

Abstract

The invention relates to the field of auto parts, in particular to a side lumbar support self-adaptive adjustment system for an automobile seat and a working method thereof. It includes a body all-terrain trigger button module, and is characterized in that: the ECU module is respectively connected to the GPS module and the steering wheel angle sensor module in two ways, and the GPS module is sequentially connected to the vehicle map module, the CAN / LIN protocol module, and the waist support receiving control module. , DC permanent magnet brush motor and shape memory alloy valve module, and finally feed back to the ECU module to process the terrain; the steering wheel angle sensor module is sequentially connected to another CAN / LIN protocol module, another waist support receiving control module, another direct Flow permanent magnet brush motor and another shape memory alloy valve module and finally feedback to the ECU module to process the absolute angle. The invention reduces the displacement in the Y direction of the H point to improve driving safety and maneuverability, realizes precise positioning of the terrain by means of GPS, accurately determines the terrain by an angle sensor, and can be used normally in an environment of ‑40°C~+80°C.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a side lumbar support self-adaptive adjustment system for an auto seat and a working method thereof. Background technique [0002] At present, SUVs and sports cars are very popular in the market. The conventional function is to install a pneumatic lumbar support in the side wing area of ​​the seat to clamp the driver tightly by inflating two airbags at the same time. However, there is no terrain-adaptive inflation and deflation function yet. side lumbar support. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention designs a side lumbar support self-adaptive adjustment system for automobile seats and its working method, which can self-adaptively control the inflation and deflation of the airbags on both sides of the backrest independently according to the curved road conditions. [0004] In order to achieve the above object, ...
