Waist lateral support control method in automobile driving and steering process

Abstract

The invention provides a waist lateral support control method in the automobile driving and steering process. The method includes the steps of initial straight-line driving control, steering control and control of straight-line driving recovery. The method is implemented based on an automobile seat backrest device. The device includes a seat module, a lateral support module and a start module. Theseat module includes a base skeleton, the lateral support module includes a telescopic rod, and the rear end of the telescopic rod is provided with a push rod motor. The front end of the telescopic rod is provided with an elastic airbag, the start module includes a trigger element and a sensing element. The lateral support automobile seat backrest device is the device which can provide unidirectional lateral support for the passengers in the automobile steering process, meanwhile can automatically fit the passenger's waist and back, and provides sufficient back support.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a method for controlling lateral lumbar support during driving and steering of an automobile. Background technique [0002] A car seat is a device for the driver and passengers in the car. The car seat usually includes a skeleton, a spring and a foam core. The spring and foam core set inside can provide good support for the driver and passenger's lower back At the same time, it can also ensure the comfort and stability of the ride; the existing car seats are equipped with lateral support pads that are bent forward at a certain angle on both sides, and their function is to provide passengers with a seat when the car is turning. Provide lateral support to prevent passengers from deviating from the seat due to centrifugal force; however, its bending angle and length are also not suitable for passengers of different sizes, and lateral support will appear for overweight passengers Insuffici...

[0002] A car seat is a device for the driver and passengers in the car. The car seat usually includes a skeleton, a spring and a foam core. The spring and foam core set inside can provide good support for the driver and passenger's lower back At the same time, it can also ensure the comfort and stability of the ride; the existing car seats are equipped with lateral support pads that are bent forward at a certain angle on both sides, and their function is to provide passengers with a seat when the car is turning. Provide lateral support to prevent passengers from deviating from the seat due to centrifugal force; however, its bending angle and length are also not suitable for passengers of different sizes, and lateral support will appear for overweight passengers Insufficient, and for thinner passengers, there will be excessive lateral support, which will hinder their driving operation, so their lateral support can not achieve a good effect; in addition, because the foam core of the car seat uses a molding process, Therefore, the undulating curvature of its surface cannot be adjusted according to the arc of the passenger's waist. For passengers of different heights and weights, the support requirements of the waist are different, so the general-purpose car seat will have insufficient support for the passenger's waist and back. Phenomenon, resulting in passenger discomfort after a long ride; in summary, there are defects
