Abstract: A vehicle braking control device of the invention includes, when a direction in which a brake operating member is displaced to increase the hydraulic pressure in a master chamber is assumed to be an operating direction, a correlation value output unit that outputs a correlation value that correlates to an amount of decrease in operational reaction force acting on the brake operating member in a direction opposite to the operating direction during a braking operation, prior to start of the switching control; and a control unit that controls the regenerative braking device so that, as the amount of decrease in operational reaction force indicated by the correlation value being output from the correlation value output unit is large, the regenerative braking force at the start of the switching control decreases.

Abstract: Taking a stroke within a period from when an operation of a brake operating member is started to when a predetermined stroke operation is performed as an ineffective stroke in which the master cylinder pressure is not generated, a control means controls an amount of differential pressure formed by a differential control valve such that a hydraulic braking force that corresponds to a stroke of the brake operating member is generated during the ineffective stroke, and even after the stroke of the brake operating member exceeds the ineffective stroke, increases the wheel cylinder pressure by performing raising of the amount of differential pressure formed by the differential pressure control valve by a predetermined raising amount with respect to the amount of differential pressure during the ineffective stroke.

Abstract: A control apparatus for a vehicle includes processing circuitry. The processing circuitry calculates a target torque such that the greater the amount of brake operation is, the smaller the target torque becomes. The processing circuitry controls the drive motor such that the creep torque is smaller when brake operation is being performed by the driver than when the brake operation is not being performed by the driver. The control circuitry controls the brake device such that, when the brake operation is being performed by the driver, the brake torque approaches a target brake torque. The processing circuitry sets a decrease gradient of the creep torque to be smaller than a decrease gradient of the target torque when the brake operation amount is increased under a condition in which the creep torque is being output by the drive motor.
