The invention discloses an anti-pinch method and device for an automobile seat and a storage medium, the method comprises a sensing step, a decision step and an execution step, and the method comprises the following steps: S1, sensing: collecting current data when a motor in a seat system moves, and processing the current data to obtain current data In; converting the processed current data into a current change rate delta I; hall sensor data in a seat system are collected, Hall pulse counting is obtained, integration is converted into an absolute position P, and then the speed change rate delta V is obtained; s2, decision making: setting a current change threshold value delta It, setting a speed change threshold value delta Vt, and judging that the seat system needs to enter an anti-pinch state only when delta I is greater than delta It and delta V is greater than delta Vt; after it is judged that anti-pinch needs to be triggered, the execution module controls the corresponding motor to operate reversely till the reverse operation distance reaches a set value, and then the seat system exits from the anti-pinch state. According to the invention, the stability problem of an anti-pinch algorithm is solved, and the error reversal rate in the movement process is reduced.
本发明公开了一种汽车座椅防夹方法、装置及存储介质,方法包括感知步骤、决策步骤和执行步骤,如下:S1感知:采集座椅系统中电机运动时的电流数据,对电流数据进行处理,得到电流数据In;将处理后得到的电流数据转换为电流变化率ΔI;采集座椅系统中霍尔传感器数据,获得霍尔脉冲计数,积分转换为绝对位置P,进而得到速度变化率ΔV;S2决策:设置电流变化阈值ΔIt,设置速度变化阈值ΔVt,只有当ΔI>ΔIt且ΔV>ΔVt时,判断座椅系统需要进入防夹状态;S3执行:在判断需要触发防夹后,执行模块控制相应的电机反向运行,直至反向运行距离达到设定值,随后座椅系统退出防夹状态。本发明解决防夹算法的稳定性问题,降低了运动过程中的误反转率。
