An estimation device detects, by means of a detection unit, electrical characteristics between a plurality of detection points of a vehicle seat provided with a flexible material that has electrical conductivity and that changes in accordance with a change in applied pressure. The estimation unit estimates the posture state of the occupant of the vehicle seat on the basis of the electrical characteristics of the vehicle seat using the learning model. A learning model is obtained by using, as learning data, electrical characteristics when pressure is applied to a vehicle seat and posture state information indicating the posture state of an occupant applying pressure to the vehicle seat, and by learning such that the electrical characteristics are input and the posture state information is output. The electrical characteristics are learned to be input, and the posture state of the occupant corresponding to the input electrical characteristics is output.
估计装置通过检测部来检测具备柔软材料的车辆用座椅的多个检测点之间的电气特性,该柔软材料具有导电性、且电气特性与被赋予的压力的变化相应地变化。估计部使用学习模型,根据车辆用座椅的电气特性来估计车辆用座椅的乘员的姿势状态。对于将对车辆用座椅施加了压力时的电气特性和表示对车辆用座椅施加压力的乘员的姿势状态的姿势状态信息用作学习用数据、以将该电气特性作为输入且输出姿势状态信息的方式进行学习而得到的学习模型,学习为输入电气特性且输出与所输入的电气特性对应的乘员的姿势状态。
