Abstract: A vehicle braking device includes a storage unit storing a first relationship between the brake operation amount and a first differential pressure when the brake operation amount is within a range less than a first brake operation amount and is increasing, and a second relationship between the brake operation amount and the first differential pressure when the brake operation amount is within a range less than the first brake operation amount and is decreasing. In the first relationship a relationship in which the first differential pressure increases as the brake operation amount increases, and in the second relationship a relationship in which the first differential pressure is reduced as the brake operation amount is reduced. The first differential pressure per unit reduction in the brake operation amount in the second relationship is greater than the first differential pressure per unit increase of the brake operation amount in the first relationship.

Abstract: A braking force control apparatus includes a fluid pressure generation mechanism, a braking mechanism and an electric control unit. The fluid pressure generation mechanism causes a braking mechanism to generate a required fluid pressure. The braking mechanism applies a braking force depending on the required fluid pressure to each of wheels through the pressing of a braking member against a rotating rotary member due to the required fluid pressure. The electronic control unit performs, when the required fluid pressure is generated and a vehicle state shifts from a running state to a stopped state at a first time point, stop-time boost control to boost the required fluid pressure at and after the first time point.

Abstract: Provided is a vehicle braking control device applicable to a vehicle equipped with an electric-powered parking braking device, a hydraulic braking device and a regenerative braking device. The braking control device comprises a first braking control unit and a second braking control unit. When a parking braking operation is performed while the vehicle is travelling, the first braking control unit implements a first braking process which increases the braking force to the vehicle by operating the hydraulic braking device. When the braking force to the vehicle needs to be increased in a situation where the first braking process is being implemented, the second braking control unit implements a second braking process which increases the braking force to the vehicle by operating the regenerative braking device.
