Abstract:
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.
