The disclosed vehicle braking device controls a hydraulic brake system () and a regeneration brake system () mounted on a vehicle () in accordance with an acceleration value and a brake value, and includes a first divider (), a second divider (), and a controller (). The first divider () divides a driver demand torque set according to the accelerator value into a target coast torque and a remaining torque. The second divider () divides a sum of a deceleration torque set according to the brake value and the target coast torque divided by the first divider () into a hydraulic-brake demand torque and a regeneration-brake demand torque. The controller () controls the hydraulic brake system (), using the hydraulic-brake demand torque, and controls the regeneration brake system (), using a total regeneration brake torque calculated from the remaining torque and the regeneration-brake demand torque. This configuration can improve the feeling of operating the brake, resolving the feeling of the shortage of deceleration.
