The invention provides a motor control device, a motor unit, and a vehicle. A motor control device according to one embodiment of the present invention is provided with: a motor drive circuit having an upper arm and a lower arm; an arithmetic processing device that controls the motor drive circuit; a replacement circuit that replaces the arithmetic processing device; and a mode switching unit that switches a control mode between a first control mode in which the motor drive circuit is controlled by the arithmetic processing device and a second control mode in which the motor drive circuit is controlled by the alternative circuit, in accordance with the state of the arithmetic processing device. When the state of the arithmetic processing device changes from the normal state to the abnormal state, the mode switching unit switches the control mode from the first control mode to the second control mode. In the second control mode, the replacement circuit controls the switching of the switching elements included in the upper and lower arms in accordance with the states of the upper and lower arms.

    本发明提供马达控制装置、马达单元以及车辆。本发明的一个方式的马达控制装置具有:马达驱动电路,其具有上侧臂和下侧臂;运算处理装置,其对马达驱动电路进行控制;替代电路,其代替运算处理装置;以及模式切换部,其根据运算处理装置的状态而在由运算处理装置控制马达驱动电路的第1控制模式与由替代电路控制马达驱动电路的第2控制模式之间切换控制模式。在运算处理装置的状态从正常状态变化为了异常状态时,模式切换部将控制模式从第1控制模式切换为第2控制模式。在第2控制模式下,替代电路根据上侧臂和下侧臂的状态来控制包含于上侧臂和下侧臂中的开关元件的切换。
