An emergency braking device including an actuator (2), a pressurizing circuit (3) supplying the actuator (2) via a control pressure and a discharge circuit (4). The discharge circuit (4) includes restrictors (13, 14) for controlling the pressure and/or flow rate of the supply fluid of the actuator (2) during a discharge of the actuator. The restrictors (13, 14) are configured to define an intermediate pressure between a low pressure level and the control pressure of the actuator (2).

The invention relates to an emergency braking device comprising an actuator (2), a pressurizing circuit (3) supplying the actuator (2) via a control pressure and a discharge circuit (4), characterized in that the discharge circuit (4) comprises means (13, 14) for controlling the pressure and/or flow rate of the supply fluid of the actuator (2) during a discharge of the actuator, these control means (13, 14) being configured to define an intermediate pressure between a low pressure level and the control pressure of the actuator (2).

a brake control system adapted to prevent or reduce noise is provided.

A brake control system switches a pressure increase mode between first pressure increase that closes a differential pressure valve placed between a master cylinder and a wheel cylinder and activates a pump to increase wheel cylinder hydraulic pressure and second pressure increase that allows brake fluid to leak through the differential pressure valve and activates the pump to increase the wheel cylinder hydraulic pressure, according to the state of a vehicle.
