The invention discloses an electric forklift and a steering control system and method thereof. The steering control system comprises a steering motor, a drive module, a signal collecting module and a controller module, wherein the steering motor provides power to the steering of the electric forklift; the drive module is connected with the steering motor; the signal collecting module comprises a first proximity switch and a direction sensor, the signal collecting module acquires starting and stopping signals according to the distance between the first proximity switch and a steering wheel sector area and acquires the rotation phase of a steering wheel according to the detecting signals of the direction sensor; the controller module is respectively connected with the drive module and the signal collecting module and used for controlling the starting and stopping of the steering motor through the drive module according the starting and stopping signals and controlling the operation of the steering motor through the drive module according to the rotation phase after the steering motor is started so as to control the electric steering of the electric forklift. The steering control system has the advantages that steering motor real-time response can be achieved, mechanical operation is reduced, and steering efficiency is increased.
