The invention discloses a brake caliper assembly and a clamping and releasing control method thereof, and belongs to the technical field of automobile brake systems, the brake caliper assembly comprises an actuator and a brake caliper body, the actuator comprises an outer shell, a motor and a reduction gear mechanism, the motor and the reduction gear mechanism are arranged in the outer shell, and an output shaft of the motor is connected with the brake caliper body through the reduction gear mechanism. One or more energy storage parts are installed between the reduction gear mechanism and the outer shell or the brake caliper body, or a plurality of energy storage parts are installed between the reduction gear mechanism and the outer shell and between the reduction gear mechanism and the brake caliper body, so that the motor has reverse release force under the power failure condition. Friction force and assembly clearances among all mechanisms in the actuator can be eliminated, residual clamping force generate
