The electric steering control device comprises a steering control vane handle, an electric steering part, a steering processor, a steering control angle sensor and a steering executing angle sensor, wherein the steering control angle sensor is used for sensing a rotating angle X of the steering control vane handle; the steering executing angle sensor is used for sensing a rotating angle Y of the electric steering part; when the steering control vane handle is rotated by an operator, a rotating angle signal is inputted to the steering processor by the steering control angle sensor; the electric steering part is used for receiving a control signal outputted by the steering processor and correspondingly executing the rotating angle Y; the rotating angle Y is changed following the rotating angle X; and a value of Y:X when X is within a preset control resetting angle scope is less than the value of Y:X when X is beyond the control resetting angle scope. The electric steering control device provided by the invention is used for reducing the difficulty in controlling the vehicle to run straightly and preventing a turning radius of the vehicle from being overlarge, thereby forming ideal balance between the straight running and the turning radius.
