AI Technical Summary
Technical Problem
Existing seat motor control methods lack flexibility and cannot meet the needs of different usage scenarios, resulting in seat adjustments that do not meet user requirements.
Method used
Based on vehicle operation data and occupant body shape information, dynamic characteristic equations of a multi-motor system are constructed to determine the candidate setpoint sequence of the motors. The target setpoint sequence is then selected through comprehensive fitness to achieve coordinated control of the multi-motor system.
Benefits of technology
It improves the control precision and response efficiency of the multi-motor system, making the seat adjustment more suitable for actual application scenarios and enhancing ride comfort.

Abstract
This application provides a multi-motor control method, device, electronic device, and storage medium for a seat. The method includes: constructing a dynamic characteristic equation for a multi-motor system of the seat based on current vehicle operating data and the body shape information of the occupant in the seat; the multi-motor system includes multiple motors; for each motor, determining multiple candidate setpoint sequences based on the motor's dynamic characteristic equation; determining the comprehensive fitness of the multiple candidate setpoint sequences, and determining a target setpoint sequence from the multiple candidate setpoint sequences based on the comprehensive fitness; the target setpoint sequence includes the target speed and target position of the motor; and controlling the multi-motor system according to the target speed and target position of each of the multiple motors. This method is used to adaptively and collaboratively control the multi-motor system of the seat according to the actual application scenario, so that the seat adjustment conforms to the actual application scenario.
