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.

    本发明揭示了一种铰接式车辆线控转向系统及方法,所述系统包括第一电子转向控制单元,第二电子转向控制单元,信号源单元,转向油缸总成,多个液压管路及其上的电子控制阀总成,电子转向油泵总成,以及转向油壶总成;信号源单元与第一电子转向控制单元和第二电子转向控制单元相连接,以提供转向指令;第一电子转向控制单元和第二电子转向控制单元皆与电子转向油泵总成相连接,并依据转向指令使得电子转向油泵总成工作,电子转向油泵总成连接至电子控制阀总成,使得电子控制阀总成控制各液压管路的接通或断开,转向油缸总成分别与各液压管路和转向油壶总成相连接,以进行转向动作。本发明能够实现线控转向系统的全冗余。
