The present invention is a steering system for use in test driving of an automated vehicle, comprising a manual steering device configured to manually steer the vehicle, a steering axle (30) attached to the manual steering device, and a direct drive motor (35) controllably affecting torque on the steering axle (30), the direct drive motor (35) has an axis of rotation (37) coaxial with the steering axle (30). The steering system is characterized in that it has at least two predetermined states characterizing different driving conditions, where each predetermined state has at least one predetermined disengagement limit, and in that it further comprises a controller assembly operable based on a control parameter, the controller assembly being configured to detect an actual predetermined state of the vehicle, and the controller assembly initiates a disengagement of the direct drive motor (35) if at least one predetermined disengagement limit corresponding to the actual predetermined state is reached based on a difference between the specified value of the control parameter and the actual value of the control parameter. The invention also relates to a detachment method, as well as a data processing system, a computer program product and a computer readable medium for performing the method.
本发明是一种用于在自动车辆的测试驾驶中使用的转向系统,包括手动转向装置,其构造成手动转向车辆,转向车桥(30),其附接到手动转向装置,以及直接驱动马达(35),其可控制地影响转向车桥(30)上的扭矩,其中,直接驱动马达(35)具有与转向车桥(30)同轴的旋转轴线(37)。转向系统的特点在于它具有表征不同的驾驶状况的至少两个预定状态,其中每个预定状态具有至少一个预定的脱离限制,以及它还包括基于控制参数可操作的控制器组件,该控制器组件构造成检测车辆的实际预定状态,以及控制器组件在以下情况下启动直接驱动马达(35)的脱离,即,基于控制参数的规定值和控制参数的实际值之间的差值,如果达到与实际预定状态对应的至少一个预定的脱离限制的情况。本发明还涉及一种脱离方法,以及执行该方法的数据处理系统、计算机程序产品和计算机可读介质。
