Abstract

A motor control unit (1) controls an operation of a motor (2) connected to a wheel (4) via a clutch (3) that allows or interrupts torque transmission between the motor (2) and the wheel (4). The motor control unit (1) includes: a microcomputer (11) that outputs a motor control signal S_m; a driving circuit (12) that supplies driving electric power to the motor (2) based on the motor control signal S_m; and a capacitor (C) provided at an intermediate portion of a power supply line (Lp) that connects the driving circuit (12) and a driving power supply (15) to each other. The microcomputer (11) carries out electric discharge from the capacitor (C) by supplying electric power generated by electric charges stored in the capacitor (C) to the motor (2) such that torque is generated by the motor (2) and an angular velocity of the motor (2) becomes less than or equal to a prescribed angular velocity, with torque transmission between the motor (2) and the wheel (4) interrupted by the clutch (3), after a driving relay (16) is turned off.
