摘要： A vehicle brake hydraulic pressure control apparatus includes a hydraulic pressure adjusting unit, a split road determining section, a differential pressure control section, and a hydraulic pressure adjusting and driving section. The hydraulic pressure adjusting unit individually adjusts brake fluid pressures acting on wheel brakes for wheels. The split road determining section determines whether road surfaces which the wheels are in contact with constitute a split road. In a state where the split road determining section determines during execution of antilock braking control that the road surfaces constitute the split road, the differential pressure control section determines command pressures for the wheel brakes so that differential pressures between the brake fluid pressures of the right and left wheel brakes are equal to or less than a permissible differential pressure. The hydraulic pressure adjusting and driving section controls the hydraulic pressure adjusting unit based on the determined command pressures.

摘要： A wheel deceleration calculating sections individually calculate, as negative values, wheel decelerations of front and rear wheels. If, at a time when the antilock braking control for at least one of the right and left front wheels is started or at a time when the antilock braking control for at least one of the right and left rear wheels is started, (i) a maximum value of the wheel decelerations calculated by the wheel deceleration calculating sections is equal to or larger than a first predetermined value and (ii) a difference between the wheel decelerations of the right and left front wheels or the right and left rear wheels which are in an antilock braking control state is equal to or larger than a second predetermined value, a split road determining section determines that road surfaces constitute a split road.

摘要： One embodiment provides a vehicle brake hydraulic controller including a wheel speed acquiring section; a wheel deceleration calculator; a vehicle velocity calculator; and a locking tendency determination section. The vehicle velocity calculator calculates a vehicle deceleration based on a temporary vehicle deceleration corresponding to an acceleration sensor value and calculates a vehicle velocity based on the calculated vehicle deceleration. The vehicle velocity calculator calculates the temporary vehicle deceleration by offsetting a first correction amount to a deceleration side in relation to the acceleration sensor value. When a brake pedal operation amount by a driver is equal to or smaller than a first threshold and that an absolute value of the wheel deceleration is equal to or larger than an absolute value of a second threshold are met, the first correction amount is set to be smaller than when the conditions are not met.

摘要： A vehicle brake hydraulic pressure control apparatus includes an adding section and a control differential pressure setting section. The adding section adds a feedback differential pressure obtained by executing a PI operation in accordance with a yaw rate deviation which is a difference between a target yaw rate being set to a value at which a vehicle turns to a higher coefficient-of-friction road side and an actual yaw rate and a feedforward differential pressure obtained by adding (i) a differential pressure based on a steering angle and (ii) a differential pressure based on a velocity of a vehicle body and the target yaw rate. The control differential pressure setting section sets a control differential pressure based on a value obtained by the adding section, after a predetermined time elapses since start of differential pressure control.
