Side waist support self-adaptive adjusting system for automobile seat and working method thereof

Abstract

The invention relates to the field of automobile parts, in particular to a side waist support self-adaptive adjusting system for an automobile seat and a working method thereof. The system comprises avehicle body all-terrain trigger key module which is characterized in that an ECU module is divided into two paths and is respectively connected with a GPS module and a steering wheel angle sensor module, the GPS module is sequentially connected with a vehicle-mounted map module, a CAN / LIN protocol module and a waist support receiving control module, a direct current permanent magnet brush motorand a shape memory alloy air valve module and is finally fed back to the ECU module to process the terrain; the steering wheel angle sensor module is sequentially connected with another CAN / LIN protocol module, another waist support receiving control module, another direct current permanent magnet brush motor and another shape memory alloy air valve module and is finally fed back to the ECU moduleto process an absolute angle. Compared with the prior art, the system has the advantages that the Y-direction displacement of the H point is reduced so as to improve the driving safety and the controllability, the accurate positioning of the terrain is achieved by using the GPS, the terrain is accurately judged through the angle sensor, and the system can be normally used under the environment of40 DEG C to 80 DEG C.

Description

Technical field [0001] The invention relates to the field of auto parts, in particular to a side lumbar support self-adapting adjustment system for car seats and a working method thereof. Background technique [0002] At present, SUVs and sports sedans are particularly popular on the market. The conventional function is to install pneumatic lumbar support in the seat side wing area to clamp the driver by inflating two air bags at the same time, but there is no adaptive terrain charging and discharging function yet. Side lumbar support. Summary of the invention [0003] In order to overcome the shortcomings of the prior art, the present invention designs a side lumbar support adaptive adjustment system for car seats and a working method thereof, which can adaptively and individually control the inflation and deflation of the air bags on both sides of the backrest according to the curved road conditions. [0004] In order to achieve the above objectives, a side lumbar support adaptiv...
