Vehicle brake system for preventing brake noise

摘要

A brake noise detecting portion detects brake noise generated in respective wheels by braking operation in a vehicle by a normal friction brake device in a vehicle running state. When the brake noise is detected in at least one of the wheels, if a brake-noise generation wheel in which the brake noise is generated is at least one of first left and right wheels, first target braking force is reduced by a first brake noise suppression variation amount, whereby it becomes new first target braking force. The new first target braking force is then applied to the first left and right wheels. If the brake-noise generation wheel is at least one of the second left and right wheels, second target braking force is reduced by a second brake noise suppression variation amount, whereby it becomes new second target braking force. The new second target braking force is applied to the second left and right wheels. Subsequently, braking force equivalent to a sum of the first and/or second brake noise suppression variation amount that are used in reduction and setting of the first and/or second target braking force is applied as the target parking braking force to the second left and right wheels by an electric parking brake.
