PURPOSE: A brake booster for a vehicle can provide optimum pedal feel and boosting ratio according to vehicle conditions by deforming the piezoelectric element using current. CONSTITUTION: A brake booster for a vehicle comprises a reaction disk(520), a plunger(700), and a piezoelectric element(705). The plunger is positioned opposite the reaction disk. The piezoelectric element is installed on the leading end of the plunger, and controlled by a voltage regulator(920). |
