The invention provides a deceleration control device, an industrial vehicle, a deceleration control method, and a storage medium, which can alleviate discomfort feeled by an operator due to deceleration operation during uphill. A deceleration control device for an industrial vehicle includes a storage unit that stores a predetermined torque threshold value, a speed calculation unit, a torque calculation unit, a difference calculation unit, and a deceleration correction unit. When a deceleration operation is performed, a speed calculation unit calculates a target speed, and a torque calculation unit calculates a torque command value. When the calculated torque command value exceeds the torque threshold value, the difference calculation unit calculates the difference between the torque command value and the torque threshold value, and the deceleration correction unit corrects the deceleration on the basis of the calculated difference so that the calculated torque command value becomes equal to or less than the torque threshold value. The torque calculation unit corrects the torque command value, and the motor operates on the basis of the corrected torque command value, thereby decelerating the uphill vehicle at a deceleration equal to or greater than a deceleration based on gravity.
本发明提供一种减速控制装置、工业车辆、减速控制方法及存储介质,减轻因上坡中的减速操作而使操作员感到的不适感。减速控制装置用于工业车辆,包括:存储规定的转矩阈值的存储部、速度算出部、转矩算出部、差分算出部、以及减速度修正部。当进行减速操作时,速度算出部算出目标速度,转矩算出部算出转矩指令值。当算出的转矩指令值超过转矩阈值时,差分算出部算出转矩指令值与转矩阈值的差分,减速度修正部基于算出的差分,对减速度进行修正以使算出的转矩指令值成为转矩阈值以下。转矩算出部对转矩指令值进行修正,马达基于修正后的转矩指令值来运行,由此使上坡中的车辆以基于重力的减速度以上的减速度进行减速。
