The invention relates to the technical field of vehicles, in particular to a hand release detection method and device for a vehicle steering wheel, and the method comprises the steps: obtaining a first angular acceleration of the end part, connected with the steering wheel, of a torsion bar, and obtaining a second angular acceleration of the other end opposite to the end part; calculating real-time rotational inertia and damping of the steering wheel according to the first angular acceleration and the second angular acceleration based on a preset kinetic equation; according to the real-time rotational inertia and damping, the actual state of steering wheel operation of the driver is recognized, and the actual state is determined to be a hand-held state or a hand-released state. According to the embodiment of the invention, the real-time rotational inertia and the dynamic damping of the steering wheel can be monitored, so that the actual condition that the driver holds the steering wheel is judged, the misjudgment phenomenon in the traditional hand-out detection process is avoided, the hand-out detection accuracy is improved, and the method is more reliable and accurate.
本申请涉及车辆技术领域,特别涉及一种车辆方向盘的脱手检测方法及装置,其中,方法包括:获取扭杆与方向盘相连的端部的第一角加速度的同时,获取与端部相对的另一端的第二角加速度;基于预设动力学方程,根据第一角加速度和第二角加速度计算方向盘的实时转动惯量及阻尼;根据实时转动惯量及阻尼识别驾驶员对方向盘操作的实际状态,确定实际状态为手握状态或者脱手状态。本申请实施例可以通过监测方向盘的实时转动惯量与动态阻尼,从而判断驾驶员手握方向盘的实际情况,避免了传统脱手检测过程中的误判现象,提高脱手检测的精确性,更加可靠准确。
