摘要
Disclosed a steering control system used for an electric forklift, an electric forklift and a method for controlling an electric forklift. The steering control system includes: a brushless DC motor (1); a steering wheel encoder (2), configured to detect a rotating speed signal and a direction signal of a steering wheel of the electric forklift; a power driver (3), connected with the brushless DC motor (1) and configured to drive the brushless DC motor (1); a sampler (4), connected with the brushless DC motor (1) and configured to sample an operation of the brushless DC motor (1) to generate a sampling signal; and a controller (5), connected with the steering wheel encoder (2), the power driver (3) and the sampler (4) respectively and configured to generate a PWM control signal according to the rotating speed signal and the direction signal of the steering wheel, the sampling signal and a predetermined control strategy to control the brushless DC motor.
