  • Motor control device and brake fluid pressure control device for vehicle
    Patent number: 11155251
    Abstract: A motor control device includes a drive control device that controls turning on/off of a motor, and a voltage obtaining device that obtains a voltage across terminals of the motor. The drive control device determines whether or not the motor drive signal is OFF (ST01). If the determination is Yes, the drive control device determines whether or not the voltage across the terminals, which is obtained by the voltage obtaining device, has decreased and reached a target voltage (ST02). If the determination at ST02 is Yes, an ON time is set on the basis of the immediately preceding 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). Low-rotational-speed motor control can be performed while suppressing heat generation in a motor relay.
