  • Electric brake booster equipped with a pressure balance detecting device
    Patent number: 11225236
    Abstract: An electric brake booster is equipped with a pressure balance detecting device, which generates braking force. The electric brake booster includes: a first pressure device, which generates pressure as the driver manipulates the brake pedal; a second pressure device, which generates the same pressure as the first pressure device and generates driving power; a master chamber, which receives resultant force of brake pedal effort and driving power of a motor from a master piston that moves in the second pressure device; and a pressure balance detecting device, which detects whether a predetermined ratio is maintained between the pressure of the first pressure device applied to one side of the pressure balance detecting device and the pressure of the master chamber applied to the other side of the pressure balance detecting device.
