[Problem] An object of the present invention is to provide a motor control unit that driving-controls a motor having the dual-system windings, even in a case that one driving control system is an abnormality (including a failure), turns-ON of one common reverse-connection protection-FET by a driving signal of the other normal driving control system, and achieves a miniaturization and a reduction in costs, an electric power steering apparatus that is equipped with the motor control unit, and a vehicle. [Means for solving the problem] The present invention is the motor control unit, comprising: an MCU to control the motor having dual-system motor windings, dual-system inverters to drive the respective dual-system motor windings via dual-system driving sections, and one reverse-connection protection-FET that is connected between the dual-system inverters and a power supply, wherein the reverse-connection protection-FET is turned-ON or turned-OFF by a logical sum of gate driving signals from the dual-system gate driving sections.
