BRAKING CONTROL DEVICE FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a braking control device for a vehicle, the braking control device achieving highly accurate braking force control by securing a sufficient booster negative pressure regardless of the traveling state or braking operation state of the vehicle.

SOLUTION: The braking control device for the vehicle is equipped with: a brake booster 12 for increasing and transmitting an operation force generated by the operation of a brake pedal 11 by using the negative pressure of intake air of an engine 101; and a master cylinder 13 for outputting as a braking force, a master cylinder pressure generated with an operation force increased by the brake booster 12. When the slip ratio of a wheel is higher than a preset judgment value, or when a road surface friction coefficient is lower than the preset judgment value, a brake ECU 116 drives the engine 101 by the engine 101 or a generator 103 to adjust the intake negative pressure to a high level.
