Abstract: A motor control unit includes: a microcomputer that outputs a motor control signal; a driving circuit that supplies driving electric power to the motor based on the motor control signal; and a capacitor provided at an intermediate portion of a power supply line that connects the driving circuit and a driving power supply to each other. The microcomputer carries out electric discharge from the capacitor by supplying electric power generated by electric charges stored in the capacitor to the motor such that torque is generated by the motor and an angular velocity of the motor becomes less than or equal to a prescribed angular velocity, with torque transmission between the motor and the wheel interrupted by the clutch after a driving relay is turned off.

Abstract: A drive circuit device includes a circuit board having a multilayer structure, which includes first to fourth circuit conductor layers, and first to third insulating layers; and heat sinks that dissipate heat of the circuit board to an outside. An upper FET state is embedded in the first insulating layer, and a lower FET state is embedded in the second insulating layer. The upper FET and the lower FET are disposed so that a region in which the upper FET is positioned and a region in which the lower FET is positioned overlap each other in a stacking direction. A lead-out portion is formed at a second circuit pattern of the circuit conductor layer, the lead-out portion extending from the circuit board in a direction orthogonal to the stacking direction, and being connected to the heat sinks so that heat is transferred to the heat sinks.
