Abstract
An electric truck steer-by-wire system and a net-work uncertainty control method therefor. Said system comprises: a master control electric power module (14), a slave control electric power module (18), a road-sensing motor module (4), a steering wheel (1), an upper steering column (3), a lower steering column (10), a rack and pinion steering mechanism (12), wheels (13), a first steering angle sensor (2), a second steering angle sensor (11), a steering domain controller (8), and a vehicle-mounted CAN network (9). By means of the design of the master and slave controllers and actuating mechanisms, the system combines the advantages of steering angle tracking, torque tracking and current tracking, there-by satisfying the steering response requirements and power requirements of the electric truck, and further enhancing the robustness and fault-tolerant performance of the system under a random network time lag.
