Title:
A braking force control device for vehicles
Document Type and Number:
Japanese Patent JP5974447
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent a driver from feeling discomfort during brake operation when the piston speed, as a moving speed of a master cylinder piston, is high.SOLUTION: A vehicle braking force control device includes a brake pedal 1, an electric booster 2, a master cylinder 3, a deviation calculation unit 60, a pedal stepping force calculation unit 61, and a target deceleration calculation unit 69. The deviation calculation unit 60 calculates a transitional change in pedal stepping force which becomes larger as the piston speed of a primary piston 11 becomes higher, as a correction value H. The pedal stepping force calculation unit 61 calculates a control pedal stepping force by correcting the pedal stepping force (e-ACT reaction force) based on the master cylinder pressure, with the correction value H.
