Abstract:
In a motor control device that is used for, for example, an electric power steering system or another vehicle steering system equipped with a motor, a relay circuit (40) that serves as a power supply breaker is provided in a power feed line (Lp2) of a pre-driver (22) of a circuit that is a component of the motor control device. The operation of the relay circuit (40) is controlled by a relay signal (S_rly) output from a microcomputer (21).
