Field: Transport (Mechanical engineering)
Classification: CPC B | IPC B

Claim 5:
6. A method of controlling an electrohydraulic brake, comprising:
sensing, by a stroke sensor, a pedaling amount of a brake pedal;
generating, by an electronic control unit, a first braking signal when the pedaling amount is less than or equal to a first reference, and generating and transmitting, by the electronic control unit, a second brake signal to an electronic stability control (ESC) system when the pedaling amount is greater than the first reference; and
opening or closing a plurality of inlet valves disposed in the ESC system in response to the first or second braking signal to change a pressure of a brake fluid discharged from a main master cylinder to brake a plurality of wheel brake assemblies,
wherein the generating and transmitting a first braking signal and a second brake signal to an ESC system includes
controlling the ESC system so that a fluid pressure supplied to the ESC system brakes only part of the plurality of wheel brake assemblies when the first braking signal is received, and controlling the ESC system so that the fluid pressure supplied to the ESC system brakes all of the plurality of wheel brake assemblies when the second braking signal is received, and
wherein an increasing rate of a braking force applied to only the part of the plurality of wheel brake assemblies when the first braking signal is received is different from an increasing rate of a braking force applied to a remaining part of the plurality of wheel brake assemblies when the second braking signal is received.
