PURPOSE: An electrical parking brake for vehicle is provided to precisely control the cancel of a parking brake by precisely sensing the initial tension of the small load which is hanged on the parking brake. CONSTITUTION: An electrical parking brake for vehicle comprises a housing(101), an electric motor(103), a reduction gear box(105), a screw shaft(107) and a nut shaft(109). The electric motor is installed in one side of the housing. The reduction gear box is connected to the electric motor and is installed in the housing having the reduction gear. The screw shaft is installed within the housing in order to be driven with the reduction gear box. The tension sensing module is installed in one side of the screw shaft or the nut shaft. The cable joint interlinks the tension sensing module and parking cable. The controller receives signals from the tension sensing module and controls the electric motor.
