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.

Abstract: A braking device for a vehicle includes a friction brake device, a regeneration bake device, a control portion which controls the friction braking force and the regeneration braking force through a cooperative control and a state judging portion which judges whether a vehicle state is in a stopped state or a non-braking operation state where the braking operation is not performed, The control portion executes a factor change control which suppresses an increase of change inclination of the friction braking force by changing a factor relating to a friction used when the hydraulic pressure is converted into the friction braking force to an increasing side and returns the factor to a value at a non-operation of the factor change control when the vehicle state is judged to be in the stopped state or the non-braking operation state by the state judging portion.

Abstract: Provided is a vehicular brake apparatus capable of suppressing the occurrence of pedal shock. In this vehicular brake apparatus, a master cylinder forms a second hydraulic chamber neighboring to a first hydraulic chamber through a seal member. The seal member is arranged at a position facing the first hydraulic chamber and the second hydraulic chamber to be movable in the axial direction relative to the master cylinder. A first hydraulic pressure generating portion executes a movement restriction hydraulic pressure control such that when the operation information obtained by the operation information obtaining portion indicates that the brake operating member is not operated, the first hydraulic pressure which is higher than the second hydraulic pressure is generated in advance and consecutively, the larger a value relating to an operating amount in the operation information obtained by the operation information obtaining portion, the higher the first hydraulic pressure is generated.
