Brake system for vehicle

A brake system for a vehicle, the brake system comprising:

• first brake devices respectively provided in two vehicle wheels of a vehicle and configured to perform a braking operation by transmitted liquid pressure;
• second brake devices respectively provided in the other two vehicle wheels of the vehicle and configured to perform a braking operation by an embedded electromechanical actuator;
• a reservoir configured to store a pressing medium;
• a master cylinder comprising a master chamber, and a master piston provided in the master chamber and provided to be displaceable by a brake pedal;
• a hydraulic actuator configured to generate the liquid pressure by an electrical signal outputted in response to a displacement amount of the brake pedal;
• a hydraulic circuit configured to control the liquid pressure to be transmitted to the first brake device;
• a first electronic control unit configured to control the hydraulic actuator and the hydraulic circuit so that the first brake device generates a braking force in response to the displacement amount of the brake pedal;
• and
• a second electronic control unit configured to control the electromechanical actuator so that the second brake device generates a braking force in response to the displacement amount of the brake pedal.

A brake system for a vehicle, the brake system comprising:

• a hydraulic actuator hydraulically connected to a first brake device provided in a first wheel related to a first axle of a vehicle;
• a first motor configured to operate the hydraulic actuator;
• a power transmission mechanism mechanically connected to a second brake device provided in a second wheel related to a second axle different from the first axle;
• a second motor configured to operate the power transmission mechanism;
• a first control unit configured to control the first motor to supply liquid pressure to the first brake device or recover the liquid pressure on the basis that an output signal of a pedal displacement sensor of the vehicle is received;
• and
• a second control unit configured to control the second motor to operate or release the second brake device in response to a control signal on the basis of the output signal of the pedal displacement sensor of the vehicle,
• wherein the first control unit is connected directly to the pedal displacement sensor, and
• wherein the second control unit is not connected directly to the pedal displacement sensor.
