<p><P>PROBLEM TO BE SOLVED: To provide a brake hydraulic pressure control device configured to reduce rush current generated immediately after the start of supplying current to a motor when a main control section for controlling the motor is used as a drive circuit and a sub control section is used as a digital computer. <P>SOLUTION: A control device 40 for controlling a motor 20 to adjust accumulator pressure of an accumulator includes a digital computer 41 and a drive circuit 42. The digital computer 41 starts PWM control to raise an accumulator pressure when the accumulator pressure of the accumulator decreases below a pressure lower limit value. The drive circuit 42 includes a delay circuit 80 for starting the motor control by the drive circuit 42 after the digital computer starts PWM control. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
