Abstract

A control method for an automotive seat is applied to a child safety seat. The method includes: acquiring a distance between an automotive door and the seat after the automotive door is opened; determining that the distance is greater than or equal to a preset threshold; and controlling the seat to rotate to a preset position. The control method acquires the distance between the automotive door and the seat to determine whether the automotive door is open, and compares the acquired distance with the preset threshold to determine whether the automotive door is open to a certain angle. In this way, the control method determines whether a user intends to use the child seat. When the acquired distance between the automotive door and the seat is greater than or equal to the preset threshold, the control method controls the seat to rotate automatically to an execution position.

Description

CROSS REFERENCE TO THE RELATED APPLICATIONS This application is based upon and claims priority to Chinese Patent Application No. 202310744103.8, filed on Jun. 21, 2023, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD The present application relates to the technical field of automotive seats, and in particular to a control method for an automotive seat. BACKGROUND Child safety seats are designed to facilitate parents in taking care of and protecting children. At present, in order to further facilitate parents in placing children on child safety seats, there are some rotatable child safety seats emerging on the market. When the parent want to place a child on the seat, the seat can be rotated to a suitable angle to align with the automotive door, making it easy for the parent to place the child directly onto the seat from the automotive door. However, for the child safety seat with the rotation function on the market, the rotation of the seat requires manual activation of a button. In actual use, the parent may hold the child or carry other objects, making it inconvenient for the parent to activate the button. Therefore, the rotatable child safety seat needs further improvement. SUMMARY In response to the above technical issues, the present application provides a control method for an automotive seat. The control method provides an automatic rotation function for a seat, such that when an automotive door is opened, the seat can rotate automatically without the need for manual activation, greatly facilitating the use of a parent. An embodiment of the present application provides a control method for an automotive seat, applied to a child safety seat, and including: acquiring a distance between an automotive door and the seat after the automotive door is opened;determining that the distance is greater than or equal to a preset threshold; andcontrolling the seat to rotate to a preset position. Compared with the prior art, in the present application, the control method acquires the distance between the automotive door and the seat to determine whether the automotive door is open, and compares the acquired distance with the preset threshold to determine whether the automotive door is open to a certain angle. The preset threshold indicates the distance between the automotive door and the seat when the automotive door is opened to a certain angle. Through the preset threshold, the control method can determine whether the user has opened the automotive door enough and whether the user intends to place a child on the seat or take the child away from the seat. When the acquired distance between the automotive door and the seat is greater than or equal to the preset threshold, it indicates that the user intends to use the seat. At this point, the seat can be controlled to rotate automatically to an execution position, making it easy for the user to use the seat. In the present application, the control method determines whether the seat needs to rotate automatically based on the opening degree of the automotive door, avoiding the error of rotating when the automotive door is slightly opened, and improving the accuracy of automatic rotation of the seat. In addition, the seat can rotate automatically for user convenience, greatly facilitating user experience. In some optional embodiments, before acquiring the distance between the automotive door and the seat after the automotive door is opened, the method includes: acquiring, by a sensor, a distance between the automotive door and the seat when the automotive door is closed as an initial distance. In some optional embodiments, after acquiring the initial distance, the method includes: determining the preset threshold based on the initial distance. In some optional embodiments, before controlling the seat to rotate to the preset position when determining that the distance is greater than the preset threshold, the method includes: waiting for a first preset time. In some optional embodiments, the method further includes: acquiring, by sensors on two sides of the seat after the seat is mounted, a left distance and aright distance between the automotive doors and the seat when the automotive doors are closed;comparing the left distance and the right distance to determine an in-vehicle mounting position of the seat; andalternatively,manually setting the in-vehicle mounting position of the seat. In some optional embodiments, the seat is connected to a control panel for controlling seat modes; the method further includes:choosing an automatic control mode for the seat, such that the seat enters the automatic control mode, and the seat is configured to rotate automatically towards the automotive door and reset automatically;alternatively,choosing a manual control mode for the seat, such that the seat enters the manual control mode, and the seat is merely configured to rotate manually towards the automotive door and rotate manually to reset; andal
