A control device(100) serving as a torque estimation device includes a storage device (120) and a processing circuit (110). The storage device (120) stores data of a trained neural network. The trained neural network is trained using training data including data of an actually-measured torque that is measured, data of an accelerator operation amount in a period of a predetermined length up to a time point of measurement of the actually-measured torque, and data of an acceleration of a vehicle from the time point of measurement of the actually-measured torque onward. The processing circuit (110) inputs, to the trained neural network stored in the storage device (120), input data including the data of the accelerator operation amount and the data of the acceleration of the vehicle, to estimate a torque generated in a power transmission member (300).

    本公开提供一种转矩推测装置。作为转矩推测装置的控制装置(100)具备存储装置(120)和处理电路(110)。存储装置(120)中存储有使用教师数据训练得到的已学习神经网络的数据,该教师数据包括测量得到的实测转矩的数据、实测转矩的测量时间点以前的既定长度的期间中的加速踏板开度的数据、以及实测转矩的测量时间点以后的车辆的加速度的数据。处理电路(110)将包括加速踏板开度的数据和车辆的加速度的数据的输入数据输入到存储于存储装置(120)的已学习神经网络,推测在变速器(300)中发生的转矩。
