An apparatus for updating a pre-stored setting value for controlling boost power of an electric booster, the apparatus comprising:
- a control unit including a processor;
- and
- a storage medium recording one or more programs configured to be executable by the processor;
- a measuring unit configured for measuring braking characteristics including pedal stroke, deceleration, and hydraulic pressure applied from the electric booster to a braking unit during braking through a braking test of a vehicle, and
- wherein the control unit is configured for updating the pre-stored setting value so that the deceleration includes desired target deceleration based on the measured braking characteristics,
- wherein the pre-stored setting value is proportional to the pedal stroke, and is a value for setting a magnitude of the hydraulic pressure.
