Embodiment 1

[0063] In order to solve the problem that the adjustment inertial force of the electric seat of the car in the prior art is relatively large, which reduces the driving experience of the driver and passengers, and at the same time, in order to make the adjustment of the speed more accurate, such as figure 1 As shown, the present invention proposes a speed control method for an electric seat, which adjusts the front and rear positions of the seat through a brushless motor, including steps:

[0064] S1: Obtain the initial position signal of the electric seat and the real-time position signal during the adjustment process through the Hall magnetic encoder, and obtain the real-time speed signal of the brushless motor;

[0065] S2: Obtain the position planning curve of the electric seat, the speed planning curve and the target speed of the brushless motor according to the initial position signal and the target position signal.

[0066] Wherein, the target position of the electric se...

Embodiment 2

[0102] In order to better understand the technical content of the present invention, this embodiment illustrates the present invention in the form of system structure composition, such as figure 2 As shown, a speed control system for an electric seat, which adjusts the front and rear positions of the seat through a brushless motor, including:

[0103] Hall magnetic encoder, used to obtain the initial position signal of the electric seat and the real-time position signal during the adjustment process, and obtain the real-time speed signal of the brushless motor;

[0104] The drawing unit is used to obtain the position planning curve of the electric seat, the speed planning curve and the target speed of the brushless motor according to the initial position signal and the target position signal;

[0105] The control unit obtains its current position expectation value on the position planning curve according to the real-time position signal, and obtains its current speed expectat...

Abstract

The invention discloses a speed control method and system for an electric seat, relating to the field of motor adjustment, which divides the speed control of the electric seat adjustment process into three stages, which are respectively the flexible incremental stage, the uniform speed maintenance stage and the flexible In the decreasing stage, through the third-order expansion state observation and proportional control, the total disturbance of the observer can be returned to the observer as a return parameter, thereby reducing the steady-state error, so that the driver and passengers can obtain a better driving experience. The adjustment of the electric seat is more in line with the position planning curve. At the same time, through the setting of the electric seat retraction mechanism, the seat can be retracted in time when it encounters an obstacle, avoiding objects being clamped, and avoiding accidental injury to the driver and passengers while also avoiding damage to the seat.

Description

technical field [0001] The invention relates to the field of motor regulation, in particular to a speed regulation method and system for an electric seat. Background technique [0002] Car seat is an important part of car interior parts, which is related to the comfort of the driver. In today's society, the requirements for car driving comfort are increasing day by day, and the electric seat can facilitate the driver and occupant to accurately adjust the seat position before and during driving, so as to relieve the physical condition and improve the safety and comfort. Electric seat adjustment can achieve different position adjustment requirements, such as front and rear, height or angle adjustment, to meet the position requirements of different drivers for the seat, and the adjustment is more convenient, safe, and position accuracy is more accurate. [0003] The front and rear adjustment motor of the car electric seat is to adjust the front and rear positions of the seat i...
