摘要： A solenoid valve for a brake system, which has a simplified configuration and can be easily manufactured with reduced manufacturing costs. The solenoid valve includes valve seat member integrally formed with a seat portion having a first orifice, an opening/closing member slidably installed in the valve seat member, the opening/closing member having an inner passage formed through the opening/closing member, an outer passage formed at an outer surface of the opening/closing member, a second orifice formed at one end of the opening/closing member, the second orifice having a smaller diameter than that of the first orifice, and a first opening/closing portion formed at the other end of the opening/closing member to open or close the first orifice, an opening spring to move the opening/closing member, for opening of the first orifice, a sleeve having a first end coupled to an outer surface of the valve seat member and a flange formed at the first end so as to be fixed to a modulator block, a valve core coupled to a second end of the sleeve, opposite to the first end of the sleeve, an armature slidably mounted in the sleeve, the armature having a second opening/closing portion to open or close the second orifice, and a restoring spring to press the armature toward the second orifice.

摘要： Disclosed herein are an electronic parking brake system and a control method thereof. The electronic parking brake system includes brakes, a parking cable to apply braking force to the brakes, a motor to apply tension to the parking cable, a current sensor to sense current of the motor, and an electronic control unit to judge the braking force of the brakes based on the current of the motor, and to control driving of the motor based on the braking force. The electronic parking brake system senses the tension of the parking cable using the small-sized current sensor, thereby easily obtaining a space in which the current sensor is installed and thus reducing a product size of the electronic parking brake system. Further, the electronic parking brake system senses the tension of the parking cable using the inexpensive current sensor, thereby reducing manufacturing costs of the electronic parking brake system and reducing costs of an electronic parking brake system product and a vehicle provided with the same.
