Abstract
An electronically controlled brake system for automobiles is disclosed. This brake system has a low/intermediate pressure accumulator, which is connected to both the NC-type solenoid valves and the oil suction line so as to store pressurized oil discharged from the wheel brakes during an ABS pressure reducing mode, and feed the stored pressurized oil to the inlet of an oil pump during an ABS pressure increasing mode. This accumulator also stores pressurized oil outputted from the oil pump to feed the stored pressurized oil to the inlet of the oil pump during an ESP mode. The low/intermediate pressure accumulator of this invention thus acts as a low pressure accumulator during an ABS mode, and acts as an intermediate pressure accumulator during an ESP mode. Due to such a low/intermediate pressure accumulator, it is possible to reduce the number of parts making up the brake system.
