The invention discloses an articulated vehicle steer-by-wire system and method. The system comprises a first electronic steering control unit, a second electronic steering control unit, a signal source unit, a steering oil cylinder assembly, a plurality of hydraulic pipelines, electronic control valve assemblies on the hydraulic pipelines, an electronic steering oil pump assembly and a steering oil can assembly. The signal source unit is connected with the first electronic steering control unit and the second electronic steering control unit so as to provide a steering instruction; the first electronic steering control unit and the second electronic steering control unit are both connected with the electronic steering oil pump assembly and enable the electronic steering oil pump assembly to work according to a steering instruction, and the electronic steering oil pump assembly is connected to the electronic control valve assembly so that the electronic control valve assembly can control connection or disconnection of hydraulic pipelines. The steering oil cylinder assembly is connected with the hydraulic pipelines and the steering oil can assembly so as to conduct steering action. According to the invention, full redundancy of the steer-by-wire system can be realized.
