The present invention relates to a steer-by-wire system for operating a steering wheel and a steering column. The present disclosure proposes a steering-by-wire system (100) comprising at least a steering wheel actuator for operating a steering wheel and a steering column. The steering wheel actuates the steering wheel actuator by means of a brushless DC motor (M3). The steering wheel actuator adjusts the steering column in a tilt direction by means of a first brushed DC motor (M1) and adjusts the steering column in a telescoping direction by means of a second brushed DC motor (M2). M1 and M2 are configured to operate via two separate H-bridges (101, 102) having a shared arm (106) of a switch. M3 is configured to operate with two three-phase H-bridges (103), wherein one three-phase H-bridge (105) is a network of switches of M1 and M3.
本发明涉及一种用于操作方向盘及转向柱的线控转向系统。本公开提出了一种线控转向系统(100),其包括至少用于操作方向盘及转向柱的方向盘致动器。所述方向盘借助于无刷DC马达(M3)致动所述方向盘致动器。所述方向盘致动器借助于第一有刷DC马达(M1)沿倾斜方向调节所述转向柱并且借助于第二有刷DC马达(M2)沿伸缩方向调节所述转向柱。M1及M2被配置为经由具有开关的共享臂(106)的两个分开的H桥(101、102)操作。M3被配置为与两个三相H桥(103)一起操作,其中一个三相H桥(105)是M1与M3的开关的网络。
