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.

Abstract: A torque sensor including a first step formed on an inner peripheral surface of a sensor housing, a second step formed on an outer peripheral surface of a detection coil assembly, the first and second steps axially supporting each other, and a groove formed on the outer peripheral surface of the detection coil assembly at a position adjacent to the second step such that the groove faces an inner surface portion of the first step, so that the first step penetrates the groove while being plastically deformed when the detection coil assembly is pressed toward the first step, thereby causing the detection coil assembly to be fixed to the inner peripheral surface of the sensor housing. Since the detection coil assembly is fixed in the sensor housing through the structural modification of the sensor housing and detection coil assembly, without using a separate fixing member, it is possible to effectively achieve the fixing of the detection coil assembly, and thus, to reduce the number of elements in the torque sensor.
