The invention discloses a method for dynamically adjusting the shape and the position of a seat surface of an automobile seat, and relates to the field of automobile seat adjusting.The method comprises the steps that firstly, the optimal seat posture corresponding to a current user is obtained through a human-seat coupling model and human body shape data, and the shape and the position of the seat surface of the automobile seat are adjusted based on seat parameter values of the optimal seat posture; on the basis, acquiring automobile seat pressure characteristic data of a current user in a preset time length every set time length, and finely adjusting the current seat posture based on the automobile seat pressure characteristic data: optimizing the constructed target function by using the automobile seat pressure characteristic data through a Bayesian optimization algorithm, and adjusting the current seat posture according to the target function; according to the method, the optimal automobile seat parameter value output by the target function is obtained, the automobile seat is adjusted based on the optimal automobile seat parameter value, personalized adjustment of the automobile seat is achieved based on the body characteristics of the passenger, and on the basis, active adjustment of the shape and the position of the seat face of the automobile seat in the driving process of the user is achieved.

    本发明公开了一种汽车座椅椅面形状与位置的动态调节方法,涉及汽车座椅调整领域,其首先通过人‑椅耦合模型与人体体型数据获取当前用户对应的最优座椅姿态,基于最优座椅姿态的座椅参数值调整汽车座椅的椅面形状与位置;在此基础上,每间隔设定时长,则获取当前用户预设时长内的汽车座椅压力特征数据,并基于汽车座椅压力特征数据微调当前的座椅姿态:通过贝叶斯优化算法利用汽车座椅压力特征数据优化构建的目标函数,得到目标函数输出的最优汽车座椅参数值,并基于最优汽车座椅参数值调整汽车座椅,其基于乘客的身体特征实现了对汽车座椅的个性化调整,并在此基础上,实现了在用户驾驶过程中对汽车座椅椅面形状与位置的主动调节。
