Abstract
An electric brake apparatus of the present invention relates to an electronic brake apparatus that includes a pump unit driven based on driving of a motor and a plurality of wheel cylinders each of which receives a fluid pressure generated by the pump unit. The electric brake apparatus includes: a hydraulic circuit disposed between the pump unit and the wheel cylinders; a plurality of wheel valves that regulate a fluid flow between the hydraulic circuit and the wheel cylinders; and an electronic control unit that controls the wheel valves and the motor, wherein the electronic control unit controls the wheel valves and the motor on the basis of an input of a driver's pedaling of a brake pedal and a need for electronic stability control.
Claims8
An electric brake apparatus that includes a pump unit driven based on driving of a motor and a plurality of wheel cylinders, each of which receives a fluid pressure generated by the pump unit, the electric brake apparatus comprising:
- a hydraulic circuit disposed between the pump unit and the wheel cylinders;
- a plurality of wheel valves that regulate a fluid flow between the hydraulic circuit and the wheel cylinders;
- and
- an electronic control unit that controls the wheel valves and the motor,
- wherein the electronic control unit controls the wheel valves and the motor on the basis of an input of a driver stepping on a brake pedal and a need for electronic stability control.
A control method of an electric brake apparatus that includes a pump unit driven based on driving of a motor and a plurality of wheel cylinders, each of which receives a fluid pressure generated by the pump unit, the control method comprising:
- detecting one of an input of a user braking and a need for electronic stability control of a vehicle;
- driving the motor and discharging a fluid into a hydraulic circuit disposed between the pump unit and the wheel cylinders by an electronic control unit;
- controlling a plurality of wheel valves disposed between the hydraulic circuit and the wheel cylinders by the electronic control unit;
- and
- generating braking power for one of a plurality of wheels on the basis of the controlling of the plurality of wheel valves.
