The invention provides a method and device for judging the hand release state of a steering wheel of a vehicle and the vehicle. Acquiring a steering wheel hand torque applied to a vehicle steering wheel by a driver and corresponding to each of a plurality of acquisition moments included in the current driving period; respectively judging whether each steering wheel hand torque and the acquisition moment corresponding to the steering wheel hand torque meet a hand release judgment condition corresponding to the acquired driving road surface type corresponding to the current driving period of the vehicle; and if yes, judging that the driver is in a vehicle steering wheel hand-release state at the acquisition moment when the hand-release judgment condition is met. Through the method, the research and development investment cost of the vehicle is reduced, and the accuracy and efficiency of judging the hand release state of the vehicle steering wheel are improved.
本申请提供了一种车辆方向盘脱手状态的判定方法、装置及车辆,所述判定方法包括:针对车辆在行驶过程中的当前行驶周期,获取所述当前行驶周期所包括的多个采集时刻中的每个采集时刻对应的由驾驶员对车辆方向盘施加的方向盘手力矩;分别判断所述每个方向盘手力矩和该方向盘手力矩对应的采集时刻是否满足采集到的车辆在所述当前行驶周期对应的行驶路面类型所对应的脱手判定条件;若满足,则判定驾驶员在满足脱手判定条件的采集时刻处于车辆方向盘脱手状态。通过上述方法,减少了车辆的研发投入成本,提高了车辆方向盘脱手状态判定的准确性和效率。
