MOTOR CONTROL DEVICE AND BRAKE FLUID PRESSURE CONTROL DEVICE FOR VEHICLE
[Problem] To provide a motor control device and a brake fluid pressure control device which provide a technology that enables low-rotational-frequency control of a motor while suppressing the generation of heat. [Solution] A motor control device equipped with a drive control unit that controls the turning on/off of a motor, and a voltage acquisition unit that acquires the voltage across the terminals of the motor. The drive control unit 32 confirms whether the motor drive signal is off (ST01), and if the result is Yes the drive control unit 32 confirms whether the voltage across the terminals as obtained by the voltage acquisition unit 33 has decreased and reached a target voltage (ST02). If the result in ST02 is Yes an On time is set on the basis of the immediately previous Off time (ST03), and the motor drive signal is switched from Off to On (ST04). After the On time elapses the motor drive signal is switched from On to Off (ST05). [Effect] Low-rotational-frequency control of a motor can be performed while suppressing the generation of heat in a motor relay.
