1. An apparatus for braking a vehicle, comprising:
a plurality of wheel brakes configured to provide a braking force to one or more front wheels and one or more rear wheels;
a first actuator comprising:
a first hydraulic circuit configured to supply a braking force to at least some of the plurality of wheel brakes,
a first master cylinder configured to adjust a hydraulic pressure of the first hydraulic circuit, and
a first motor;
a second actuator comprising:
a second hydraulic circuit configured to supply a braking force to at least a remainder of the plurality of wheel brakes,
a second master cylinder configured to adjust a hydraulic pressure of the second hydraulic circuit, and
a second motor;
an electronic parking brake (EPB) configured to generate a braking force on the one or more rear wheels;
a regenerative braking system configured to generate a regenerative braking force; and
a first electronic control unit (ECU) configured to, upon determining whether the first actuator and the second actuator malfunction, control at least one of the first actuator, the second actuator, the electronic parking brake, or the regenerative braking system,
wherein the first ECU is configured, upon determining that the second actuator malfunctions, to control the electronic parking brake to provide a braking force to the one or more rear wheels and to control the first actuator to brake at least some of the plurality of wheel brakes, and
the first ECU is configured, upon determining that the first actuator malfunctions, to control the regenerative braking system to generate the regenerative braking force on the one or more front wheels and to control the second actuator to brake at least the remainder of the plurality of wheel brakes.
