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.

Abstract: A brake fluid pressure control device for a vehicle that includes a wheel speed obtaining device to obtain wheel speed, and a vehicle body deceleration calculating means to calculate a vehicle body deceleration on the basis of the wheel speed. If a condition is satisfied in which the vehicle body deceleration continues to stay at a low rate of less than or equal to a predetermined threshold value for a predetermined period of time, the pressure increasing rate in pressure increasing control is altered to a higher value than before the condition is satisfied. The brake fluid pressure of a brake caliper can quickly be brought close to the fluid pressure of a master cylinder. Therefore, it is possible to improve the brake responsiveness when the brake is re-operated by the driver during the ABS control, thereby reducing the driver's feeling of wrongness and strangeness.
