Embodiment Construction

[0023] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] A lumbar support control method includes the following steps:

[0025] S1. When a collision occurs, the collision sensor generates a collision signal and transmits it to the airbag controller;

[0026] S2. Then the airbag controller judges whether a rear collision occurs. If no rear collision occurs, the lumbar support 1 is not retracted. If the airbag controller determines that a rear collision occurs,...

Abstract

The invention discloses a lumbar support control method which comprises the following steps S1, when collision occurs, enabling a collision sensor to generate a collision signal and transmit the collision signal to an airbag controller; S2, judging whether rear collision occurs or not by the air bag controller, if not, not withdrawing the lumbar support, and if the rear collision occurs, transmitting a signal to the motor controller by the air bag controller; and S3, enabling a motor controller to issue a driving instruction to the lumbar support motor, so that the action of retracting the lumbar support is realized. According to the scheme, whiplash injuries to passengers during rear collision are reduced, and the safety performance of the whole automobile is improved; according to the scheme, whiplash injuries to passengers during rear collision are reduced, and the safety of the whole automobile is improved.

Description

Technical field [0001] The invention belongs to the technical field of lumbar support control, and more specifically, relates to a lumbar support control method. At the same time, the present invention also relates to a lumbar support control device. Background technique [0002] When a car is involved in a low-speed rear collision, if the lumbar support drum protrudes against the back of the occupant, it will increase the relative back movement of the head, thereby increasing the whiplash injury to the occupant. At present, this influencing factor is not fully considered in the design of car occupant protection at home and abroad. How to reduce the whiplash injury of the occupant is very important when the vehicle has a low-speed rear collision. Summary of the invention [0003] The purpose of the present invention is to solve the shortcomings existing in the prior art, and propose a lumbar support control method and device. [0004] In order to achieve the above objective, the p...
