The invention provides a motor control device, a motor device, a wiper device, and a motor control method, which can obtain sufficient output performance corresponding to a driving mode while protecting the motor device. The motor control device includes: a drive control unit that switches between a first drive mode and a second drive mode to control motor drive, and that controls an output duty ratio so as not to exceed a duty ratio upper limit value; and an upper limit value setting unit that sets a low rotation duty upper limit value in a low rotation region in which the rotation speed is equal to or less than the rotation threshold value, a maximum duty upper limit value corresponding to the maximum output value of the drive output, and an upper limit value of a transition period from the low rotation duty upper limit value to the maximum duty upper limit value in a high rotation region. When switching between the first drive mode and the second drive mode, slope information indicating a change amount of the upper limit value with respect to a change in the rotational speed during the transition is changed in accordance with the drive mode.

    本发明的马达控制装置、马达装置、雨刷装置、及马达控制方法,在保护马达装置的同时,获得与驱动模式对应的充分的输出性能。马达控制装置包括:驱动控制部,在第一驱动模式与第二驱动模式之间进行切换,以控制马达驱动,并且以不超过占空比上限值的方式对输出占空比进行控制;以及上限值设定部,设定旋转速度为旋转阈值以下的低旋转区域中的低旋转占空比上限值、与驱动输出的最大输出值对应的最大占空比上限值、以及高旋转区域中的自低旋转占空比上限值向最大占空比上限值的转移期间的上限值,以作为占空比上限值,当在第一驱动模式与第二驱动模式之间进行切换时,根据驱动模式变更表示转移期间的上限值相对于旋转速度变化的变化量的斜率信息。
