The invention discloses an electrically controlled limit device for preventing excessive automatic steering of an automobile. The electrically controlled limit device includes a limit device, a sensor and a controller, wherein the limit device is arranged between a steering wheel and wheels, and used for selectively limiting the steering angle of the steering wheel; the sensor is used for obtaining the steering angle of the steering wheel and a torque transmitted between the wheels and the steering wheel; the controller is configured to control the limit device to limit the steering of the steering wheel according to the steering angle and the torque obtained by the sensor. The electrically controlled limit device is additionally mounted on a steering shaft, so as to prevent accidental large-angle deflections of the wheels under ground impact, and improve the automobile traveling safety. The device adopting the technical scheme achieves rapider judgment and lower manufacturing cost, and can prevent the phenomenon that when a driver carelessly reduces the torque of holding the steering wheel, large-angle automatic steering of the automobile is caused by road disturbances; meanwhile, when the driver is able to or resume to control the steering, the device can voluntarily withdraw from the interference, so as to avoid interfering the steering control of the driver.
