Abstract: PURPOSE: A creep torque control system for vehicles and a method thereof are provided to improve driving safety by generating the creep torque of vehicle inversely proportionally to an extent in which a vehicle brake is released. CONSTITUTION: A creep torque control method of a vehicle is comprised of the following steps. A vehicle brake is turned on and stops in an ignition-on status(S10). The creep torque is controlled to 0 in a brake on or off status(S21). The step determines whether the operation of brake is able to be turned off(S30). If the brake is turned off, the creep torque is controlled to be generated. If the creep torque is generated, the vehicle enters into a driving mode. [Reference numerals] (S10) Vehicle stop state(power on/brake on); (S21) Creep torque off; (S30) Brake pedal off; (S40) Creep torque on(inverse proportion to pedal stroke release); (S50) Vehicle driving

Abstract: A position controller for a brake piston of a vehicle is provided to pressurize a brake pad uniformly by appropriately controlling the position of the brake piston based on pressure applied to the brake piston. A positioning controller for a brake piston of a vehicle comprises a caliper housing(1) installed on a vehicle body, a hydraulic piston(2) inserted into the caliper housing, and a hydraulic port(1a) to supply the hydraulic piston with hydraulic fluid and to drain the hydraulic fluid. The hydraulic piston is provided at a leading end thereof with a plurality of piezoelectric elements(3). The piezoelectric elements detect pressure applied to the top/bottom and left/right sides of the hydraulic piston when the hydraulic piston moves forward to compress the brake pad. The caliper housing includes four push rods(4) for correcting the position of the hydraulic piston.
