Abstract: <P>PROBLEM TO BE SOLVED: To provide an electric booster capable of improving the accuracy of control.  <P>SOLUTION: The electric booster calculates a detection value (sensor output signal) of a stroke sensor, which varies in accordance with a treading-in of a brake-pedal, and obtains an offset elimination sensor output signal (step S11) by subtracting, from this sensor output signal, an offset learning value that is obtained through an offset learning, and then generates a control signal addressed to an electric motor, in accordance with the output signal, whereby the electric motor is controlled based on the control signal. The offset elimination sensor output signal that constitutes the generation of the control signal properly reflects the stroke of an input member, and no influence of offset included in the sensor output signal is sustained any more. This enables an accurate detection of a driver's tread-in of the brake pedal, and further the improvement of accuracy in control by putting the electric motor in control through use of the control signal while securing a pedal feeling suitable for the intention of the driver.  <P>COPYRIGHT: (C)2010,JPO&INPIT
