Abstract

Electronic brake system is disclosed. An electronic brake system includes, a pressure sensor including a first pressure sensor configured to measure a hydraulic pressure of the accumulator, a second pressure sensor configured to measure a hydraulic pressure of the first hydraulic circuit, and a third pressure sensor configured to measure a hydraulic pressure of the second hydraulic circuit, a driver including one or more apply valves and release valves configured to control the hydraulic pressures of the first hydraulic circuit and the second hydraulic circuit, a determiner configured to determine that at least one of the first hydraulic circuit and the second hydraulic circuit has failed when an absolute value of a slope of the pressure measured by the first pressure sensor is greater than a preset first threshold value and the pressure measured by the first pressure sensor is less than a preset second threshold value and a controller configured to close apply valves of the first hydraulic circuit and the second hydraulic circuit when the failure has been determined, determine that a leak has occurred in one of the first and second hydraulic circuits having an amount of pressure change greater than that of the other hydraulic circuit measured on the basis of the second pressure sensor and the third pressure sensor, and control braking using only the hydraulic circuit operating normally.
