The invention discloses a safety handle which comprises a handle body, a handle base and a balancing block, wherein one end of the handle body is hinged with one end of the handle base through a handle body rotary shaft, and the other end of the handle body is provided with a slide bar; a U-shaped notch is formed in a suspension end of the slide bar; the balancing block is composed of a pedestal and a box body with an open-shaped side on the pedestal; the middle of the other side of the box body is provided with a ball head; the ball head on the balancing block abuts against the interior of the U-shaped notch of the slide bar; an electromagnetic locking mechanism is arranged vertically adjacent to the slide bar of the handle body; and the electromagnetic locking mechanism drives a pin column to pass in or through the slide bar of the handle body. The invention further discloses a control method of the safety handle. A warning signal is sent to an automobile body controller through an on-board computer, and the automobile body controller inputs a locking electric signal to the electromagnetic locking mechanism to implement a locking action on the handle body. By adopting the safetyhandle, the handle body can be prevented from opening a door lock and further opening a door due to inertia during the initial collision on the side of a car.
