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.

Abstract: A parking brake device includes a fluid unit including: a fluid pump that suctions brake fluid from a master cylinder using a first electric motor; and a pressure regulating valve that increases pressure of the brake fluid discharged by the fluid pump and supplies the increased pressure to a wheel cylinder as a brake fluid pressure, the fluid unit causing the brake fluid pressure to press a friction member against a rotating member fixed to vehicle wheels to generate a braking force, an electrically-powered unit that uses a second electric motor and generates the braking force on a parking wheel on which a parking brake is applied among the vehicle wheels, and a controller that controls the fluid unit and the electrically-powered unit. When the parking brake is actuated, the controller increases only the brake fluid pressure corresponding to the parking wheel in the wheel cylinder.

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.
