According to one or more embodiments, a steer by wire steering system includes a handwheel, and a handwheel actuator configured to secure a position of the handwheel. The securing includes determininga transition of the steer by wire steering system to an ingress/egress mode. The securing further includes, based on the determination that the steer by wire steering system is in the ingress/egressmode, computing a holding torque command based on a difference in a present angle of the handwheel and a target angle of the handwheel, which is caused by an input torque. Further, the securing includes generating a holding torque corresponding to the holding torque command to secure the position of the handwheel.

    根据一个或多个实施例,一种线控转向系统包括:方向盘;以及方向盘致动器,被构造为固定方向盘的位置。所述固定包括:确定线控转向系统向进入/退出模式的转变。所述固定还包括:基于线控转向系统处于进入/退出模式的确定,基于由输入扭矩引起的方向盘当前角度与方向盘目标角度的差计算保持扭矩命令。此外,所述固定还包括生成与保持扭矩命令相对应的保持扭矩以固定方向盘的位置。
