The invention provides a steering wheel hand release detection method and device and a vehicle, and belongs to the technical field of steering wheel hand release detection. The steering wheel out-of-hand detection method comprises the steps that after a steering system of a vehicle is powered on and assisted, a system return torque value of a steering wheel is obtained through learning; detecting an actual aligning torque value of the steering wheel in real time; generating a release state signal according to the system return torque value and the actual return torque value; and whether the steering wheel is in a hand release state or not is judged according to the request turning angle of the steering wheel, the current turning angle of the steering wheel, the hand release state signal and the actual return torque value. The steering wheel hand release detection method can meet the requirement for accuracy of function hand release detection of automatic auxiliary driving.

    本发明提供了一种方向盘脱手检测方法、检测装置及车辆,属于方向盘脱手检测技术领域。该方向盘脱手检测方法包括:在车辆的转向系统上电助力后,通过学习获得方向盘的系统回正扭矩值;实时检测所述方向盘的实际回正扭矩值;根据所述系统回正扭矩值和所述实际回正扭矩值生成脱手状态信号;根据所述方向盘的请求转角、所述方向盘的当前转角、所述脱手状态信号以及所述实际回正扭矩值判断所述方向盘是否处于脱手状态。本发明的方向盘脱手检测方法能够满足自动辅助驾驶的功能脱手检测的准确性要求。
