The drive-by-wire electric power steering column comprises a steering wheel, a sensor assembly, a shaft assembly, a controller and a load return mechanism, the steering wheel is fixedly installed at one end of the shaft assembly, the load return mechanism is connected with the other end of the shaft assembly, and the sensor assembly comprises a first sensor and a second sensor. The controller is electrically connected with the sensor assembly, the load return mechanism and the external steering execution mechanism. During steering, the controller receives signals collected by the sensor assembly and controls the external steering execution mechanism to implement power-assisted steering after operation, and meanwhile, the controller receives signals collected by the sensor assembly and controls the load return mechanism after operation, so that a damping effect on a steering wheel is achieved; and during non-steering, the load return mechanism drives the steering wheel to return. The steering column and the external steering actuating mechanism are controlled to work completely by means of electronic and electrical elements, so that the mounting position of the steering system is not limited, and the operation space of a driver is large.
本发明提供了一种线控电动助力转向管柱及车辆,包括方向盘、传感器总成、轴总成、控制器和负载回正机构,方向盘固定安装于轴总成一端,负载回正机构与轴总成另一端连接,传感器总成包括第一传感器以及第二传感器,控制器分别与传感器总成、负载回正机构以及外部转向执行机构电性连接;转向时,控制器接收来自传感器总成收集到的信号并经过运算后控制外部转向执行机构实施助力转向,同时控制器接收来自传感器总成收集到的信号并经过运算后控制负载回正机构,对方向盘起到阻尼作用;非转向时,负载回正机构驱使方向盘进行回正。转向管柱与外部转向执行机构完全依靠电子和电器元件来控制工作,使得转向系统安装位置不受限制,驾驶员操作空间大。
